The current study investigated the correlation among sperm production (milt volume, spermatocrit and sperm count), sperm motility characters and biochemical composition of seminal plasma during different seasons to estimate the quality of semen in the Spotted scat (Scatophagus argus). The sperm of 120 males were collected over a period of 2 years seasonally viz., summer, pre-monsoon, monsoon and post-monsoon. During the collection period, it was observed that there were significant (p 0.05) seasonal variations in the semen quality including sperm motility and production more in the summer season than other seasons. The osmolality of seminal plasma varied from 343.33 to 370.33 mOsm/kg. The pH of seminal plasma elevated from 7.37 to 7.63 during monsoon and summer seasons. The motility of S. argus sperms correlated with the concentration of biochemical compounds viz., Ca

OBJECTIVE To examine patient laboratory testing compliance by tracking time to submission of laboratory requisitions in Southern Alberta, Canada as part of a quality improvement initiative. METHODS Data was collected retrospectively from patients from the Chinook Primary Care Network in Alberta, Canada, who received a laboratory requisition consisting of a complete blood count (CBC) test order between September 1, 2016 and August 31, 2017. To allow for all laboratory requisitions created to be submitted within one year, the study collection period was from September 1, 2016 to August 31, 2018. Patient age, sex, and dates of laboratory requisition creation and submission were collected. The days-to-test-submission served as a marker of compliance. Association of age, sex, and clinic location with time to laboratory requisition completion was determined using Cox regression analysis. RESULTS During the study period, 70.4% (n = 1607) of laboratory requisitions created were completed within one year, and over half (50.5%) of the laboratory requisitions ordered were completed within two weeks. There were no significant associations between time to laboratory requisition submission and sex or clinic locations (P > 0.05), but there were significant associations between patients who were 20-49 or 70-79 and increased laboratory requisition compliance (P

Air pollution of indoor and outdoor environments is one of the most important environmental problems in metropolises and industrial cities. The study explores the effects of air quality on the well-being of students at Shahid Beheshti University in Tehran. The sampling of the particles was carried out in four seasons in 2017–2018. The concentration of PM≥11, PM7-11, PM4.7–7, PM3.3–4.7, PM2.1–3.3, PM1.1–2.1, PM0.7–1.1, PM0.4–0.7 and PM≤0.4 in inside and outside building was evaluated simultaneously using a direct measurement device. The length of each collection period varied from 6 to 72 h. The samples were studied by SEM/EDS and imaging was performed and the surface of particles. The effects of air quality on students were collected using a questionnaire. Based on the results, there was cough, throat irritation and psychological problems for students, especially those with asthma and respiratory problems. There were more symptoms during the summer and autumn. The life of the building, the use of natural ventilation and inadequate cooling devices are the main factor in increasing the concentration of indoor particles in the educational building. According to the result of sampling in the outside environment, the highest concentration of the particles occurred in summer and the lowest concentration in spring and winter. Due to the presence of natural ventilation in the spring and summer seasons, the trend of variation of the concentration inside the building was similar to the outside.

Sixty, finishing broilers aged 35 days were used to determine the Apparent, Nitrogen corrected and True metabolisable energy value of thevetia oil. The oil was subjected to heat treatment of 110°C for 25 minutes. Four experimental diets consisting of a basal diet and three other diets in which thevetia oil was substituted for 2.5, 5.0 and 10.0% of the basal diet. The experiment lasted for 10 days, made up of a 7-day adjustment period and a 3-day total collection period. Protein and fibre retention were significantly (P

We study the impacts of the use of trade credit on SME financial performance and operational distress in a sample of 74,036 SMEs across 19 EU countries between 2006 to 2015. Under the premise that trade credit acts as a substitute for bank credit, our results show that supplying trade credit improves profitability, but we show little evidence that such an investment is more profitable for bank credit richer SMEs, although such firms did redistribute more bank fund through trade credit to their customers. For receivers, we show that the use of trade credit finance alleviates operational distress, especially for those SMEs facing liquidity constraints, such as those which have less access to bank credit or under credit tightened periods. This distress reduction effect is also reflected in their profitability indicators. However, the longer the average collection period and credit period, the less effective the trade credit effects respectively on improving SME profitability and reducing operational distress.

A series of four experiments were conducted in carried out with cockerels but can also be which 30g DM of whole palm kernel (WPK) performed with broiler chickens and laying hens and of Palm Kernel Oil Sludge (PKOS) were (Johnson and McNab, 1983). Differences force-fed to laying hens and adult broilers between broilers and laying hens (Peterson et chickens. The length of the collection periods `` al., 1976 and adult cockerels) Mollah et al was the same (24, 30, 48 and 60hr) for both 1983) have been reported. These differences ingredients. The ingredients and their faecal may be a result of differences in nitrogen (N) materials were used to determine the apparent balance between the different bird types metabolisable energy (AME) and the true (Askbrant, 1988). metabolisable energy (TME) and their nitrogen (N) corrected forms (AMEn and TMEn). However, a possible deficiency in the rapidTMEn). bioassay for determining TME using adult Results showed that in both ingredients, at the rooster (Sibbald, 1976) is that a portion of the 48 hr collection period, no difference in the teed may be retained, explaining some of the AME and AMEN, TME and TMEn were found differences observed between AME and TME in the bird types. Complete passage of the test values. Extension of the collection period, ingredients was ensured at the 48 hr collection depending on the specific ingredient being period. The AME and AMEn values of WPK tested, was recommended for feeds which with laying hens were: 5.08 and 4.98 Kcal/kg exhibit slow rate of passage, from various DM; while those for the broiler chickens were: studies (Sibbald 1979a, b, c). This suggestion 4.88 and 4.31 Kcal/kg DM; those for PKOS was based on the reasoning that the control bird AME and AMEn with Jaying hens were: 3.14 may be in a state of tissue catabolism which and 2.98Kcal/kg DM,with the broiler chickens could increase the metabolic faecal energy the values were 3.12 and 2.96 Kcal/kg DM (FEM) plus endogenous urinary energy (UEE) respective.y. TME and TMEN values of WPK with extended fasting period (Kessler and with laying hens were 6.42 and 6.11 Kcal/kg Thomas, 1981). Since high fat diets exhibit DM; corresponding values with broiler chickens were: 6.41 and 6.09 Kcal/Kg DM. slow rate of passage (Mateos and Jerty, 1981), TME and TMEn for PKOS with laying hens it becomes necessary to investigate the time were 4.37. 4.12 Kcal/kg DM. 4.36 and 4.13 required for the whole palm kernel meal and its Kcal/kg DM, respectively were the sludge to be completely cleared from the corresponding values for broiler chickens. No alimentary tract of birds while determining their interaction between ingredients and birds was unknown bioavailable energy levels. found but there were interactions among the The purpose of the present study was, therefore bioavailable energy systems and the bird types. to determine the bioavailable energy (AME and TME) of whole palm kernel and palm kernel oil layers, broilers.

This paper presents the results of the survey and analysis of receivables practices in manufacturing companies: a case of Nepalese pharmaceuticals companies. The survey is based on the structured questionnaire completed by 209 pharmaceuticals executives of which 44 were under corporate level, 98 were under business level and 67 were operational level. The major issues dealt in the survey are concerned with the application of credit control policy, application of credit customer grading form, application techniques used to grant credit, application of "best practice" tips for effective credit control and opinion on practice of credit limit. Survey results showed that pharmaceuticals companies have desired to establish credit control policy with continuous practice of using credit application to screen new customer and renew them yearly. However, the practice of average collection period was not satisfactory in the companies. The choice of "references" for grading credit customer and ratio analysis were evident to grant credit.

Nowadays great deal of research is physiological field is conducted on experimental animals and there is a lot of criticism from the wide public on methods used. Therefore, recently there is a lot of effort focused on the welfare of the animals. Main aim of this study is to determine the effect of experimental sample collection method on the selected parameters of stress. In the experiment two sample collections of rabbit blood from marginal ear vein were realized – first using standard method with one person fixing the animal and other collecting the blood using gently fixating the animal. In the second groups experimental method of inserting the experimental animal into a sack and further collection in dark was realized. During the experiment the levels of cortisol – main stress indicator in organism and other health parameters of animals including mineral profile and haematological parameters were observed. Our results show no significant changes in levels of cortisol but also a decreasing tendency in the sample from the second (dark) collection. Haematological parameters were generally in the reference values and any significant changes except levels of lymphocytes and percent of lymphocytes which shown significant increase in the second collection period were found. Also the levels of mean corpuscular haemoglobin and percent of neutrophils unveiled a significant decrease in values. Values of mineral profile parameters have indicated no significant changes except the levels of phosphorus. Based on the result we can state that the experimental sample collection has no effect on blood parameters of the animals but we spectated a statistically insignificant decrease in the levels of cortisol which can suggest that the dark collection is possibly less stressful to the animals.

Background/purpose Trimethoprim-sulfamethoxazole (TMP-SMZ) is broadly administered to treat multiple infections, and the paucity of effective treatment alternatives for infections caused by Klebsiella pneumoniae has led to a renewed interest in TMP-SMZ. The aim of this study is to evaluate the antibacterial efficacy of TMP-SMZ against K. pneumoniae. Methods The resistance genes of K. pneumoniae clinical isolates were investigated by PCR, followed by conjugation experiments and multilocus sequence typing. Results The resistance rate of K. pneumoniae to TMP-SMZ decreased over the collection period from 26.7% (88/330) to 16.9% (56/332). The high carrying rates (173/175, 98.9%) of resistance determinants (sul genes or dfr genes) were the main mechanisms of TMP-SMZ resistance isolates, with sul1 (142/175, 81.1%) and dfrA1 (119/175, 68.0%). Only class 1 integron was detected, the prevalence of which in TMP-SMZ resistant K. pneumoniae was 63.4% (111/175). Conclusion These results provided insights into the antimicrobial efficacy of TMP-SMZ against K. pneumoniae, also illustrating the wide distribution of SMZ and TMP resistance genes among resistant K. pneumoniae. Simultaneously, the present study highlights the significance of reasonable administration and effective continued monitoring.

Data on the crude protein requirements of elk doe are nonexistent and the data are essential for their management in Korea. Therefore, this study was conducted to evaluate the crude protein requirement for maintenance of elk doe. Three female elk deer were used in 3 × 3 Latin square design with three diets containing three levels of crude protein (CP) that contained low crude protein (approximately 12%), medium crude protein (15%), and high crude protein (18%). Each three elk doe trials included a 14-day preliminary period and a 5-day collection period. Crude protein intake was 4.83, 6.26, and 9.00 g/d for 12%, 15%, and 18% of CP level, respectively. Crude protein balances were 1.04, 1.41, and 4.14 for 12%, 15%, and 18% of CP level, respectively. The maintenance requirement for CP from the regression equation between CP intake and CP balance were 3.70 g/BW0.75.

Several pathologies, such as cancer, predispose the depletion of nutritional status, which makes it essential to offer a balanced diet, which highlights the role of minerals, due to their relevance in contributing to the treatment and recovery of patients. The objective of the study was to determine the levels of calcium (Ca), potassium (K), magnesium (Mg), sodium (Na) and phosphorus (P) in hospital meals (general, bland and pasty) and in an additional meal called complement oral food (CAO) that contained foods with added proteins, carbohydrates and / or fibers, and also evaluate the suitability of each macromineral in relation to nutritional recommendations (DRIs). Samples were collected in duplicate from six daily meals and from CAO on two non-consecutive days, from a hospital in Belo Horizonte (MG). Macrominerals were determined by an optical emission spectrometer with inductively coupled plasma (ICP OES). Statistical analyzes were performed using Stata 11.0 and the statistical significance was established as p

Objective: The objective was to determine standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) in cereal grains and various co-products fed to growing pigs.Methods: Ten feed ingredients tested were barley (9.3% CP), lupin kernels (31.1% CP), and wheat (11.3% CP) as cereal grains, and 2 sources of corn gluten feed produced in China (21.6% CP) and Korea (24.6% CP), corn gluten meal (65.3% CP), lupin hulls (11.6% CP), rice bran (14.5% CP), soybean meal (44.8% CP), and wheat bran (15.4% CP) as co-products. Ten experimental diets were formulated to contain each ingredient as a sole source of N and an N-free diet was used to correct basal endogenous losses of CP and AA. All diets also contained 0.5% Cr2O3 as an indigestible index. A replicated 11×6 incomplete Latin square design with 11 dietary treatments, 6 periods, and 22 animals was employed. Twenty-two barrows with an initial body weight of 64.6±4.9 kg were equipped with a T-cannula in the distal ileum. An experimental period consisted of a 4-d adaptation period and a 2-d collection period.Results: The SID of CP in the barley, lupin kernels, wheat, 2 sources of corn gluten feed, corn gluten meal, lupin hulls, rice bran, soybean meal, and wheat bran were 84.7%, 90.5%, 90.4%, 77.4%, 74.6%, 89.5%, 90.4%, 74.4%, 86.9%, and 63.4% (standard error of the mean [SEM] = 5.3, p = 0.006), respectively. The respective SID values of Lys were 75.5%, 88.4%, 83.9%, 74.7%, 62.4%, 80.3%, 83.9%, 78.5%, 88.0%, and 71.2% (SEM = 3.3, p

The aim of this research was to evaluate bee pollen load samples collected in Tuzla Canton regarding physicochemical composition and antioxidant properties, with relation to collecting area and time of collection. Bee pollen load samples were collected in two periods: March/April and May/June at 13 locations, dried and analysed for protein, free fat, ash, moisture, total polyphenol and total flavonoid content, and antioxidant properties. The results showed that bee pollen collected in March/April had lower content of proteins, but higher content of total polyphenols and higher antioxidant activity, while total flavonoid content was not influenced by collection period. The location had significant influence on bee pollen properties.

BACKGROUND: In helicopter critical care and emergency medical services (HEMS) transportation, organizations aim for efficiency of the dispatch process. Most HEMS organizations do not provide transport under instrument flight rules (IFR), due to equipment and training cost. Boston MedFlight (BMF) provides IFR HEMS transport. We set out to determine if response time of IFR transport was superior to ground transport.METHODS: A retrospective analysis of quality improvement data was performed. Data was collected by two observers sitting in the BMF control room in varying shifts. A process map of the dispatch process, from the dispatch call to the vehicle en route was developed. Critical points in the dispatch process were determined and a variety of time differences to determine the length of processes in the dispatch calculated. We compared median time differences between visual flight rules (VFR) flight and IFR flight, between IFR flight and ground transport, and between VFR and Ground for these points using a Mann-Whitney U-test.RESULTS: During the study collection period, 443 transports occurred, of which 109 transports happened while the observers were present: 37 ground, 57 VFR, and 15 IFR. Due to weather, six IFR transports were declined. The overall time from dispatch call to vehicle en route was significantly increased for IFR flights [median: 30 min:8 s (interquartile range 19:06–49:04)] over both VFR flights [11:36 (9:24–17:06); P vs. IFR: 0.001] and ground transports [9:39 (6:59–14.51); P vs. IFR: 0.001]. Most of this increase was accounted for by increases in the time from dispatch to crew acceptance, and from rotor start to vehicle en route.DISCUSSION: IFR conditions resulted in significantly increased dispatch times over both VFR flight and ground transport. The increase is likely a result of weather check, filing an IFR flight plan, and IFR release. Dispatch algorithms should be adjusted for this time delay of IFR transports.Kamine TH, Thomas L, Davis C, Cohen J.

Election polls are the de facto mechanisms to predict political outcomes. Traditionally, they are conducted with personal interviews and questionnaires. This process is costly and time consuming, demanding the development of alternative approaches faster and less expensive. On the other hand, social media emerge as important tools for people to express their opinions about candidates in electoral scenarios. In this context, there is an increasing number of election prediction approaches using social media and opinion mining, modeling this problem in different ways. In this work, we present a survey on approaches to election predictions and discuss many possibilities of decisions in the general process of constructing solutions to this end, including the quantity of collected data, the specific social media used, the collection period, the algorithms and prediction approaches adopted, among others aspects. Our overview allowed us to identify the main factors that should be considered when predicting elections outcomes supported by social media content, as well as the main open issues and limitations of the approaches found in the literature for data science communities. In brief, the main challenges that we have found include but are not limited to: labeling data reliably during the short period of electoral campaigns, absence of a robust methodology to collect and analyze data, non-availability of domain (labeled) datasets, a lack of a pattern to evaluate the obtained results and exploration of new machine learning algorithms and methods for tackling the peculiarities of this scenario.

This study is entitled Analysis of Uncollectible Accounts Receivable Turnover Rate at CV Suryamas in OKU Regency, with the formulation of the problem is how to analyze uncollectible accounts on the turnover rate of accounts receivable at CV Suryamas in OKU Regency. The method used in this research is descriptive method. This method is used by means of research prioritizing systematic observation of existing activities to obtain appropriate and targeted results by using the analysis tools for the bad debts ratio and the accounts receivable turnover ratio. The results showed that the risk of uncollectible receivables from CV Suryamas in 2015-2019 was 0.11%. While CV Suryamas' receivables turnover in 2015-2019 was seen from the average collection ratio of 121.78%. When viewed, the ratio of non-performing receivables is 0.11%, which means that there is less risk of uncollectible receivables and the average collection ratio reaches 100%. Based on the analysis of the uncollectible accounts receivable ratio to the CV Suryamas receivable turnover ratio in OKU Regency during 2015-2019, it shows that the management of uncollectible accounts has been strived to run properly. This can be seen from the ratio of arrears whose value is less than 3% and the collection ratio reaching 100%, although the receivable turnover ratio has an impact on the inefficient use of business capital and the average collection period ratio also estimates bad debts at 60%.

Restaurantes podem propiciar doenças veiculadas por alimentos, assim, medidas de controle devem ser realizadas. Objetivou-se quantificar coliformes totais, termotolerantes e bactérias heterotróficas mesófilas na superfície da bancada da pia de manipulação, e bioaerossóis fúngicos em unidade de alimentação em uma instituição de ensino, antes e durante o processamento dos alimentos, e após higienização do local de trabalho.

AbstractRestaurants can provide food-borne diseases, so control measures must be taken. The objective of this study was to quantify total coliforms, thermotolerant bacteria and mesophilic heterotrophic bacteria on the sink basin surface, and fungal bioaerosols in a feeding unit at a teaching institution, before and during food processing, and after cleaning the workplace. Samples were collected by swab and air by exposure for 15 minutes of acidified PDA plates on different days of the week totaling sixteen samples. Total (35°C, 24/48 h) and thermotolerant coliforms (45 °C, 24 h) were quantified by inoculation of serial dilutions in VB and EC broth, respectively, and the results expressed as MLN/cm2. The counts of mesophiles (35 °C, 48 h) were performed on PCA agar and the results expressed in CFU/cm2. Anemophilous fungi cultured at 25°C for seven days were expressed in CFU/15 min. The results were analyzed in ASSISTAT 7.6 betas software. It was verified a count > 103 MLN/cm2 for total coliforms during the processing, and after sanitization, decay of 16% in relation to the initial average. Reduction of 56.3% was observed for thermotolerant coliforms. The number of mesophiles remained ≥ 3 log cycles, regardless of the collection period (before, during or after processing). 54.2% of the air samples had high counts for fungi (> 50 CFU/15 min). The results indicate the possible generation of risks and occurrence of alimentary toxinfections. When properly performed, hygiene is effective in reducing microbial load. It is suggested better procedures monitoring performed by the handlers. Keywords: Aerosols. Coliforms. Mesophiles.

his experiment was conducted to study the effect of biological and chemical treatments of olive trees by-products on chemical composition, degradability, cell wall constituents, digestibility and nutritive value and its feeding effect on productive performance of growing sheep. Eighteen (½ Finnish Landrace × ½ Rahmani) lambs with average body weight 18.00±0.40 kg and 4 months old were used in this study for 120 days. Lambs were distributed into three similar groups (6 lambs each) and randomly assigned to three experimental rations. The three respective rations composed of concentrate feed mixture (CFM) + olive trees by-products, the control ration (R1) contained untreated olive tree by-products; (R2) treatedolive trees by-productswith EM1 and (R3)treated olive trees by-products with El-mofeed. The digestibility and nutritive values of experimental rations were determined using nine adult Ossimi rams. Rumen liquor and blood samples were collected at the end of collection period. The results showed that nutrient digestibility and feeding values (TDN and DCP) were higher (P 0.05) differences were found in blood constituents (total protein, albumin, globulin, GOT, GPT and urea) among the different experimental groups. Blood sereum constituents were generally normal in all experimental groups. Growth performance with respect to total body weight gain and average daily gain (ADG) were improved by biological and chemical treatments. The same trend was observed for feed conversion and economic efficiency and the best values were recoded with R2. It was concluded that inclusion of biologically treated olive trees by-products to rations of growing (½ Finnish Landrace × ½ Rahmani) lambs could improve their performance especially treatment of olive trees by-products.

This study conducted a comparative analysis on working capital management and performance ofindustrial and consumer goods firms in Nigeria. Precisely, the study compared effect of average collectionperiod and average payment period on return on capital employed of selected industrial goods and consumergoods firms. 20 firms were randomly selected over a period of 10 years data were collected from annualreport of the firms. This study used static data analyses to analyze data. Result showed average collectionperiod and average payment period exert insignificant positive effect on return on capital employed ofindustrial goods firms, while both average collection period and average payment period exert insignificantnegative effect on return on capital employed of consumer goods firms. Independent t-test result showedsignificant mean difference between coefficient estimate corresponding to industrial and consumer goodsfirms. This study concluded that there exists significant difference between the effect of working capitalmanagement on performance of industrial goods firms and consumer goods firms when performance ismeasured in terms of return on capital employed. Hence firms in both sub-sectors should be strategic whenmanaging working capital, by setting higher average payment period in a manner that will not crowd-outtheir credit worthiness.

This study assessed working capital management and performance of listed manufacturing firms in Nigeria 20 firms were sampled, over 10 years. The study employed static data analyses and panel Granger causality test. Result showed that average collection period exerts insignificant negative effect on return on capital employed of the sampled firms, while average collection period also exerts insignificant negative effect on earnings per share of the sampled firms. The result further showed that, average payment period exerts insignificant positive effect on return on capital employed of the sampled firms, but average payment period exerts insignificant negative effect on earnings per share of the sampled firms. The study concluded that, average collection period and average payment exert insignificant effect on return on capital employed of listed manufacturing firms in Nigeria, also; average collection period and average payment period exert insignificant effect on earnings per share of listed manufacturing firms in Nigeria. Hence manufacturing firms in Nigeria should objectively manage average collection period and also maintain a consistent improvement in return on capital employed and earnings per share of listed manufacturing firms in Nigeria.

This paper aims to study the dynamic relationship between dependent variables of trade credit (net trade credit to total assets and net trade credit to sales), and six independent variables (profit margin, liquidity ratio, and the dummies collection, credit, size, and crisis) using panel vector autoregression during the period 2004-2013 considering data from eight European countries. The results indicate that net trade credit is negatively influenced by crises, forcing firms to use it less due to survival effects but imposing higher trade restrictions. Notwithstanding, net trade credit to sales is positively influenced by the liquidity ratio and profit margin, and vice-versa, but has a negative relationship with credit and collection dummies, imposing credit shortenings and forcing reliance on short-term credit. For the overall period, firms seem to have sold more than having bought on credit due to tightening trade credit, an effect of the financial crisis.

Latex is a colloidal suspended of rubber particle in rubber tree (Hevea brasiliensis). Technically, the capacity of rubber productivity can be determined by latex collectionperiod after being tapped. The objective of research was to obtain the differences of latex collection period. The study was conducted in September-November 2017 at the Sungei Putih Research Center in Experimental Estate with PB 260 (7 years tapped) on BO-2 (S/2 d3.ET2.5% Ga1.0 6/y(m)).The experimental designused a Randomized Block Design (RBD) with four treatments of latex collection periodi.e 20, 40, 60, 80 minutes after being tapped with three replicates respectively. The parameters observed was gram/tree/tapping (g/p/s), kg/ha/years, latex flow rate (ml/minutes) and total solid content (%).The results showed that latex collection period was significantly different to g/p/s, kg/ha/years and latex flow rate. Total solid content (TSC) was not significantlydifferent in all treatments. The latex collection period of 20 minutes after being tapped had higher productivity than 40, 60, 80 minutes.

The purpose of this research is to learn and explain about the effect of management control system on the increasing of performance, working process and receivables. Management control system has significant impact in affecting company’s accomplishment and how it runs the productions ahead. It also covers management of receivables in determining credit policies, receivables turnover, and monitoring of receivables aging. Management control system contains supervising of human resources which undeniably important when running the production operational. Human resources give ideas and improvisations on upcoming issues faced by the company to achieve its targets and how it contributes to assist in problem solving. Based on the study, a conclusion can be made that management control system have significant impacts on supervision of human resources, monitoring activities, human resources performance measurements, performance evaluation, credit policies, receivables turnover and monitoring of receivables aging. The analysis uncovers the causes and obstacles that restricted company from achieving its goals. For instance, receivable turnover in 2014 had experienced a decline of 0.62% from previously 12.97% to 12.35% in 2015. Nonetheless, the average collection period can still be considered effective due to being collected before due date.

Valeriana amurensis Smir. ex Kom. widely distributed in the northeast region of China and some region in Russia and Korea, and its underground parts (roots and rhizomes) being used to cure nervous system diseases such as insomnia. The active components including the essential oil and iridoids of underground parts were investigated in different harvest periods in order to evaluate the quality for the roots and rhizomes of V. amurensis. The content of the essential oil was obtained by hydrodistillation and bornyl acetate in the oil was quantitated by GC-EI. The iridoids, valepotriates were determined by potentiometric titration and the main component, valtrate was quantitated by HPLC-UV. The factors of biomass were considered in the determination of collection period. Statistical analysis of results showed that, the highest content of the essential oil per plant was 22.69 μl in withering period and then 21.58 μl in fruit ripening period, while the highest contents of bornyl acetate, valepotriates and valtrate per plant were 2.82 mg, 31.90 mg and 0.98 mg in fruit ripening period separately. Fruit ripening period was decided as the best harvest period for the content of active constituents and output of drug, and it would provide scientific basis for the artificial cultivation of V. amurensis.

This paper examines the relationship between management functions and the profits thus generated in Murata Manufacturing Co.,Ltd. The fabrication sector (manufacturing subsidiary) acquires the factory’s profits in this company through internal transfer pricing, while the headquarters,which includes R&D, keeps its own profits. The capital investment economic calculation (return on investment and collection period) was considered from the perspective of capital investment because the achievement of the fabrication sector was evaluated in the creation of the factory’s profits. Capital investment is managed through an economic calculation of capital investment in this company. However, problems have occurred from the return on investment and the collection period because of the company’s large-scale capital investment after fiscal year 2015. In addition, a new index of R&D efficiency (headquarters’ pofits/research and development spending) was used as performance metrics for the R&D section. R&D efficiency has declined in this company on the edge of fiscal year 2015, in fiscal year 2016 and in fiscal year 2017. This is because the headquarters’ profits decreased due to increased manufacturing costs because of the large-scale capital investment in fiscal years 2015 and 2017, reduced gross profits, and a drop also in the gross operating profit. Thus, trends in capital investment influence R&D efficiency.

BACKGROUND Pediatric orthopaedic surgery has become increasingly subspecialized over the past decade. The purpose of this study was to analyze the volume of pediatric sports medicine cases performed by surgeons applying for the American Board of Orthopaedic Surgeons (ABOS) Part II certification exam over the past decade, comparing caseloads according to the type(s) of fellowship completed. METHODS The ABOS database was reviewed for all surgeons applying for the ABOS Part II certification exam from 2004 to 2014. Fellowship training of the candidates was recorded as Pediatrics, Sports, and Dual-Fellowship (fellowship in both Pediatrics and Sports). All other candidates were categorized as "Other". A total of 102,424 pediatric cases (patients below 18 years) were reviewed to identify sports medicine cases performed by CPT code. Multiple linear regression and Mann-Whitney U tests were used to determine trends in case volume overall and according to fellowship training for all patients, patients ≥13 and patients

Saliva has an important role in maintaining oral health. The mucous membranes are lubricated and protected by the salivary glycoproteins and mucoids. Saliva accomplishes its mechanical cleansing and protective functions through various physical and biochemical mechanisms. Low salivary secretion rate increases the risk for various diseases in the mouth, especially dental caries. Saliva can be collected under both resting and stimulated conditions. Flow rate is usually calculated by dividing the volume of saliva per minute. The duration of the collection period is important, since the flow rate can vary with time. Measurement of whole saliva may be superior and more relevant than measurement of individual gland secretion. The reliability, validity, and correlation between different methods for measuring the flow rate of whole saliva have been studied. The salivary output of parotid glands is usually collected in a two-chambered type of suction and collection cup according to Lashley.

Background Unintentional Injuries comprise the fifth leading cause of death in Nepal in 2017, an increase of 23% compared to 1990. In Nepal, there is minimal community-derived evidence of home or occupational injuries. Our aim was to describe the epidemiology of injuries in the Makwanpur district, including the causes and risk factors associated with those injuries. Methods A cross-sectional, household survey was undertaken in three administrative areas of Nepal between April-June, 2019. Data were collected electronically about non-fatal and fatal injuries in the previous three months and five years, respectively. Results 17,593 individuals from 3,327 households were surveyed; 394 people were injured. 136/394 (34.5%) injuries occurred in homes, 109 (27.7%) were work-related. 225 (55.8%) were males, the age range was 0–87 years, 123 (30.7%) were child injuries, (0–17 yrs). The most commonly reported injury was falls (n=173, 43.9%), stumbling and tripping were the most common reasons and 73 (42.2%) occurred at home. More injuries occurred in rural administrative areas than urban areas, especially occupational injuries (occupational: chi-square=22.05, p=0.000; home: chi-square=13.89, p Conclusions Home and occupational fall injuries are common, especially in rural areas. Understanding the context of falls, especially identifying and working with particular occupational groups where they are prevalent, may identify risk factors and help target messages about primary falls prevention and interventions. Learning Outcomes Using hand-held computers and local enumerators for data collection in sample areas resulted in minimal missing data and monitoring of data quality during the collection period.

The tests currently used for the identification of SARS-CoV-2 include specimens taken from the upper and lower respiratory tract. Although recommendations from the World Health Organization prioritise the usage of a nasopharyngeal swab (NS), nasopharyngeal aspirates (NPA) are thought to be superior in identifying SARS-CoV-2 in children. To our knowledge, however, no paediatric study has been published on the subject. The aim of this study is to evaluate the diagnostic performances of NS referred to NPA for SARS-CoV-2 in children. We calculated the sensitivity and specificity of the NS referred to the NPA of the whole sample and considered both age and collection period as covariates in different analyses. We collected 300 paired samples. The NS had a specificity of 97.7% and a sensitivity of 58.1%. We found similar results for the group of subjects ≥ 6 years old, while for subjects < 6 years old, the sensitivity was 66.7% and the specificity 97.8%. Considering period as a covariate, the sensitivity and specificity for patients hospitalised in March (31 patients, 52 records) were 70.0% and 97.6%, while for patients involved in the follow-up (16 patients, 57 records), they were 57.2% and 89.7%. The NS has a low sensitivity in detecting SARS-CoV-2 in children when referred to the NPA, whereas its specificity is high. Our results suggest that in children under 6 years of age, NSs should be preferred whenever possible. Though statistically not significant, the sensitivity of the NS rises when performed before the NPA.

Background N,N-Diethyl-3-methylbenzamide (DEET) topical mosquito repellents are effective personal protection tools. However, DEET-based repellents tend to have low consumer acceptability because they are cosmetically unappealing. More attractive formulations are needed to encourage regular user compliance. This study evaluated the protective efficacy and protection duration of a new topical repellent ointment containing 15% DEET, MAÏA® compared to 20% DEET in ethanol using malaria and dengue mosquito vectors in Bagamoyo Tanzania. Methods Fully balanced 3 × 3 Latin square design studies were conducted in large semi-field chambers using laboratory strains of Anopheles gambiae sensu stricto, Anopheles arabiensis and Aedes aegypti. Human volunteers applied either MAÏA® ointment, 20% DEET or ethanol to their lower limbs 6 h before the start of tests. Approximately 100 mosquitoes per strain per replicate were released inside each chamber, with 25 mosquitoes released at regular intervals during the collection period to maintain adequate biting pressure throughout the test. Volunteers recaptured mosquitoes landing on their lower limbs for 6 h over a period of 6 to 12-h post-application of repellents. Data analysis was conducted using mixed-effects logistic regression. Results The protective efficacy of MAÏA® and 20% DEET was not statistically different for each of the mosquito strains: 95.9% vs. 97.4% against An. gambiae (OR = 1.53 [95% CI 0.93–2.51] p = 0.091); 96.8% vs 97.2% against An. arabiensis (OR = 1.08 [95% CI 0.66–1.77] p = 0.757); 93.1% vs 94.6% against Ae. aegypti (OR = 0.76 [95% CI 0.20–2.80] p = 0.675). Average complete protection time (CPT) in minutes of MAÏA® and that of DEET was similar for each of the mosquito strains: 571.6 min (95% CI 558.3–584.8) vs 575.0 min (95% CI 562.1–587.9) against An. gambiae; 585.6 min (95% CI 571.4–599.8) vs 580.9 min (95% CI 571.1–590.7) against An. arabiensis; 444.1 min (95% CI 401.8–486.5) vs 436.9 min (95% CI 405.2–468.5) against Ae. aegypti. Conclusions MAÏA® repellent ointment provides complete protection for 9 h against both An. gambiae and An. arabiensis, and 7 h against Ae. aegypti similar to 20% DEET (in ethanol). MAÏA® repellent ointment can be recommended as a tool for prevention against outdoor biting mosquitoes in tropical locations where the majority of the people spend an ample time outdoor before going to bed.
