The aim of this study is to determine the change of some physical properties (oven-dry density, weight loss, swelling and anti-swelling efficiency) and mechanical properties (compression strength parallel to grain, bending strength, modulus of elasticity in bending, janka-hardness (cross-section, radial, tangential), impact bending strength and tension strength perpendicular to grain) of wild cherry woods after heat treatment under different durations. Specimens are exposed to temperature levels of 212 °C for time spans of 1,5 and 2,5 h. Based on the findings in this study, the results showed that oven-dry density, swelling, compression strength parallel to grain, bending strength, modulus of elasticity in bending, janka-hardness (Cross-section, Radial, Tangential), impact bending strength and tension strength perpendicular to grain values decreased with increasing treatment time.

Wild cherry wood (Cerasus avium) lumber with a nominal thickness of 5 cm from Duzce region in Turkey was dried through conventional kiln drying using two different programs which are unprotective drying schedules, and protective drying schedules. The aim was to obtain the most desirable kiln schedule for keeping the wood quality at an appropriate level up to final moisture content of 12±2% was reached. Intensity of warping (twist, bow, cup, crook) occurrence, superficial, internal and end checks, residual stresses, drying rate, and moisture gradient in the dried woods were measured, and the results were analyzed. The results showed that there was a more homogeneous moisture profile, fewer occurrences of superficial checks, and absence of internal checks in the protective drying schedules due to low warping values compared to the unprotective drying schedules. Therefore, it seems that protective drying schedules might be recommended as optimum program for wild cherry lumber drying at commercial scale from Duzce region.

In this work, we consider the time-harmonic Maxwell's equations and their numerical solution with a domain decomposition method. As an innovative feature, we propose a feedforward neural network-enhanced approximation of the interface conditions between the subdomains. The advantage is that the interface condition can be updated without recomputing the Maxwell system at each step. The main part consists of a detailed description of the construction of the neural network for domain decomposition and the training process. To substantiate this proof of concept, we investigate a few subdomains in some numerical experiments with low frequencies. Therein the new approach is compared to a classical domain decomposition method. Moreover, we highlight current challenges of training and testing with different wave numbers and we provide information on the behaviour of the neural-network, such as convergence of the loss function, and different activation functions.

Objetivo: examinar el efecto de la técnica de tos de mediana intensidad durante la inyección subcutánea de heparina de bajo peso molecular sobre la severidad del dolor y la satisfacción individual en pacientes de cirugía general. Método: estudio prospectivo, cuasi experimental, que incluyó a 100 pacientes a los que se les prescribió una inyección subcutánea de heparina de bajo peso molecular una vez cada 24 horas. Cada paciente recibió dos inyecciones por el mismo investigador utilizando técnica de inyección estándar con técnica de tos de intensidad media y solo técnica de inyección estándar. Resultados: hubo una diferencia estadísticamente significativa entre las puntuaciones medias de los pacientes sobre la intensidad del dolor y los niveles de satisfacción después de las inyecciones administradas por las dos técnicas (p= 0,000). Además, se encontró que el género afectó la severidad del dolor relacionado con la inyección, pero no afectó el nivel de satisfacción individual. Conclusión: se encontró que la técnica de tos de intensidad media reduce la severidad del dolor y aumenta la satisfacción del paciente de cirugía general que reciben inyecciones subcutáneas de heparina de bajo peso molecular. Registro del ensayo: NCT05681338.

An obvious characteristic of computer games is stress, competition, and physiological alterations in the body. It is regarded as an important subject including those factors in e-sports, getting progressively popular in the digital era. The psychological and physiological impacts of e-sports, conducted in a competitive ambiance, on the body and mind over the course of competitions are not yet known. The aim of the paper is determining the impacts of players performing in e-sports games on some biochemical and hormonal factors shaped in the body during the game. In the group of research, there are twenty electronic sports volunteer players playing in e-sports games. Samples are gathered from the players in the study thirty minutes before and after electronic sports games. Given the results, it is concluded that e-sports players' ACTH, cortisol, and testosterone levels rose substantially.

Deep eutectic solvents are characterized as natural, green, biodegradable, non-flammable, non-volatile, non-toxic, odorless, colorless, easy to prepare, and easy to recycle after use. They present an opportunity to introduce new techniques for the pulping process. This study investigated the possibility of using a green deep eutectic solvents from sorghum stalks for pulp and paper production. Choline chloride/ethylene glycol was used in the preparation of eutectic mixtures in molar ratios of 4/10, 5/10, and 6/10. These eutectic mixtures were then applied as cooking liquor to sorghum stalks at two different cooking times (140 and 160 minutes). In addition, the traditional pulping methods of soda and kraft cookings were carried out using sorghum stalks and the pulps were compared with the deep eutectic solvents pulps. The results showed that the pulp production using deep eutectic solvents was accomplished successfully. Some properties of deep eutectic solvents pulps were comparable to those of the soda and kraft pulps. deep eutectic solvents can play an essential role in cleaner pulp production.

Black pine (Pinus nigra) is a significant raw material source for the forest products industry in Turkey. The purpose of this research was to study some chemical, anatomical, physical, and mechanical properties of wood obtained from juvenile black pines planted in Kavaklıdere - Muğla, originating from five different locations: Muğla, Balıkesir, Denizli, Bursa, and Kütahya. Although pines originating from Muğla and Balıkesir were good in terms of wood properties, those from Denizli, Bursa, and Kütahya exhibited no remarkable features. Black pine of Muğla origin was recommended for planting in Kavaklıdere and similar habitats, whereas pines of Denizli, Bursa, and Kütahya origins were not recommended. However, pine of Balıkesir origin may be an alternative to that of Muğla origin for black pine plantations at Kavaklıdere and similar sites.

This article analyses the correlation between populism and immigration in the EU. After examining the literature on the current state of the populist movements in the EU, along with the results of comparative fieldwork carried out in Germany, France, Italy, Greece and the Netherlands, the article seeks to understand and explain how the debates on immigration, refugees, mobility and Islam influence the rise of far-right populism in Europe. To do this, the main components of the populist discourse in Europe on immigrants and refugees are described, and the socioeconomic, political and cultural factors in populist extremism are analysed along with the resentment about diversity, multiculturalism, Islam, immigration and mobility held by the followers of populist parties in the five European countries chosen.

There is still a need to improve the production sequences of micro fibrillated and nano fibrillated celluloses to obtain more economic and better quality products. The aim of this study was to improve the production efficiency and quality of micro fibrillated and nano fibrillated celluloses by examining the enzyme (xylanase endo-1,4-) employed in pretreatment sequences. Fairly homogeneous nano fibrillated cellulose with a width of 35 ± 12 nm was produced in this study. Sequences employed to produce micro fibrillated and nano fibrillated celluloses decreased the cellulose crystallinity of bleached kraft pulp and lower total crystalline index and lateral order index values were observed for micro fibrillated and nano fibrillated celluloses in FTIR examinations. Lower crystallinities were also defined by 13C-NMR (46.2 ppm), which was substantiated with C6 peaks in the amorphous domain. Sequences to produce micro fibrillated and nano fibrillated celluloses resulted in shorter fiber dimensions with less ordered cellulose structure leading lower thermal degradation that reveal main polymer chain source from cellulose units. Dynamic mechanical thermal analysis results showed that the initial and maximum storage modulus of the nano fibrillated and micro fibrillated celluloses films were improved by 114% and 101%, respectively. The storage modulus of micro fibrillated and nano fibrillated celluloses films were 4.96 GPa and 2.66 GPa at temperature of 235°C, respectively.

ABSTRACTBACKGROUND AND OBJECTIVES: Strabismus surgery is a frequently performed pediatric ocular procedure. A frequently occurring major problem in patients receiving this treatment involves the oculocardiac reflex. This reflex is associated with an increased incidence of postoperative nausea, vomiting, and pain. The aim of this study was to investigate the effects of a sub-Tenon's block on the oculocardiac reflex, pain, and postoperative nausea and vomiting.METHODS: 40 patients aged 5-16 years with American Society of Anesthesiologists status I-II undergoing elective strabismus surgery were included in this study. Patients included were randomly assigned into two groups by using a sealed envelope method. In group 1 (n = 20), patients did not receive sub-Tenon's anesthesia. In group 2 (n = 20), following intubation, sub-Tenon's anesthesia was performed with the eye undergoing surgery. Atropine use, pain scores, oculocardiac reflex, and postoperative nausea and vomiting incidences were compared between groups.RESULTS: There were no significant differences between groups with regard to oculocardiac reflex and atropine use (p > 0.05). Pain scores 30 min post-surgery were significantly lower in group 2 than in group 1 (p < 0.05). Additional analgesic needed during the postoperative period was significantly lower in group 2 compared to group 1 (p < 0.05).CONCLUSIONS: In conclusion, we think that a sub-Tenon's block, combined with general anesthesia, is not effective and reliable in decreasing oculocardiac reflex and postoperative nausea and vomiting. However, this method is safe for reducing postoperative pain and decreasing additional analgesia required in pediatric strabismus surgery.

Background: Fibroblast growth factor 23 (FGF-23) is a phosphorus-regulating hormone. In chronic kidney disease (CKD), circulating FGF-23 levels are markedly elevated and independently associated with mortality. Left ventricular hypertrophy (LVH) is a potent risk factor for mortality in CKD, and FGFs have been implicated in the pathogenesis of myocardial hypertrophy. In addition, the effect of anemia on CV disease and LVH is well known in CKD. A relation between iron and FGF-23 metabolism is mentioned in a few studies. The aim of this study was to test the association of FGF-23 levels with echocardiographic (ECHO) and iron parameters in peritoneal dialysis patients (PD). Methods: In this cross-sectional study, 61 subjects with PD (29 women and 32 men, mean age: 46.9 ± 13.3 years, mean PD vintage: 69.5 ± 39 months) underwent echocardiograms to assess left ventricular mass index (LVMI). Medical treatments and average values of the basic laboratory results of the last 6 months for all patients were recorded. Serum FGF-23 concentrations were measured using intact FGF-23 (iFGF-23) human enzyme-linked immunosorbent assay (ELİSA) kit. According to the median levels of serum FGF-23 the patients were grouped into two (FGF-23 high and low groups). Results: Significant positive correlation was recorded between serum FGF-23 levels and LVMI (P = 0.023). There was also significant difference in terms of hemoglobin (12.1 ± 2 versus 11.0 ± 2, P = 0.017), transferrin saturation (TSAT) (24.9 ± 16.8 versus 19.5 ± 10.8, P = 0.042) between low and high FGF-23 group. Also in linear regression analysis the negative relation between FGF-23 and hemoglobin is persisted (r = 0.199, P = 0.045). Conclusions: FGF-23 is associated with LVMI, anemia and low TSAT in patients with PD. Whether increased FGF-23 is a marker or a potential mechanism of myocardial hypertrophy and anemia in patients with end-stage renal disease (ESRD) requires further study.

RESUMOObjetivoA artrite gostosa e a febre familiar do Mediterrâneo (FFM) compartilham algumas características clínicas e patológicas, como ser classificada como uma doença autoimune inflamatória, ter associação com o inflamassoma, manifestar artrite intermitente de curta duração e boa resposta a tratamentos com colchicina e anti-interleucina-1. Como o gene da febre familiar do Mediterrâneo (MEFV) é o fator causador da FFM, este estudo teve como objetivo investigar a prevalência de mutações do gene MEFV e seu efeito sobre as manifestações da doença em pacientes turcos com artrite gotosa.MétodosForam incluídos no estudo 97 pacientes com diagnóstico de artrite gotosa primária (93 M e 4 F; 54 [37-84] anos) e 100 controles saudáveis (94 M e 6 F; 57 [37-86] anos). Todos os indivíduos foram submetidos à análise do genótipo à procura de variações no MEFV. Também foi registrado o número de crises de gota, o uso de diuréticos e a história de nefrolitíase e presença de tofos.ResultadosA frequência de portadores de mutações no MEFV em pacientes e controles foi de 22,7% (n = 22) e 24% (n = 24), respectivamente. A comparação entre os pacientes e os controles não produziu diferença estatisticamente significativa em termos de frequência de portadores de mutações no MEFV (p = 0,87). As frequências alélicas de mutações no MEFV nos pacientes foram de 11,9% (n = 23) e 14% (n = 28) nos controles (p = 0,55). A presença de variantes do MEFV não mostrou qualquer associação com as características clínicas da artrite gotosa. A análise por subgrupos de pacientes revelou que aqueles com artrite gotosa com mutações tinham frequências semelhantes de tofo, história de nefrolitíase e podogra em comparação com os indivíduos sem mutações (p > 0,05).ConclusõesAs mutações no gene MEFV não exercem um papel relevante em pacientes turcos com artrite gotosa.

INTRODUCTION: The rates of multiresistant bacteria colonization or infection (MRB+) development in intensive care units are very high. The aim of this study was to determine the possible association between the risk of development of nosocomial infections and increased daily nurse workload due to understaffing in intensive care unit. METHODS: We included 168 patients. Intensity of workload and applied procedures to patients were scored with the Project de Recherché en Nursing and the Omega scores, respectively. The criteria used for infections were those defined by the Centers for Disease Control. RESULTS: Of the 168 patients, 91 (54.2%) were female and 77 (45.8%) were male patients. The mean age of female and male was 64.9 ± 6.2 years and 63.1 ± 11.9 years, respectively. The mean duration of hospitalization in intensive care unit was 18.4 ± 6.1 days. Multiresistant bacteria were isolated from cultures of 39 (23.2%) patients. The development of MRB+ infection was correlated with length of stay, Omega 1, Omega 2, Omega 3, Total Omega, daily PRN, and Total PRN (p < 0.05). There was no correlation between development of MRB+ infection with gender, age and APACHE-II scores (p > 0.05). CONCLUSION: The risk of nosocomial infection development in an intensive care unit is directly correlated with increased nurse workload, applied intervention, and length of stay. Understaffing in the intensive care unit is an important health problem that especially affects care-needing patients. Nosocomial infection development has laid a heavy burden on the economy of many countries. To control nosocomial infection development in the intensive care unit, nurse workload, staffing level, and working conditions must be arranged.

Sweet corn (Zea mays L. var. saccharata) attracts people with its amazing flavour. Adverse environmental factors decrease plant's cob yield and quality. A more effective production can be made by using resistant varieties and adjusting the sowing and plating periods. In this study, the effect of direct seed sowing and cultivating with seedlings in three different times (5, 15 and 25 May) on the sweet corn's cob yield and certain quality features have been investigated. In the research hybrid sweet corn varieties; 2201, Challenger, Merit, Sunshine and Yellow Baby were used. Ear weight, ear yield, ear length, ear diameter, sequence in ear, kernel numbers in the sequence, dry weight, TSS, chroma and hue values have been identified in the study. The values obtained from cultivation with seedling have been found higher in all of the parameters except for TSS. With the progress of cultivation period while TSS and hue values in kernels have increased (9.72 to 20.94) chroma values have decreased. Husked ear weight values have changed between 184.69 to 224.11 g in varieties. The highest ear yield (3594.33 kg da-1) has been obtained from Merit by seedling planting cultivation on 15 May.

This study examined the suitability of boron derivatives as pretreatment chemicals with regard to their efficiency in the enzymatic saccharification of sunflower stalks. It was hypothesized that the utilization of boron derivatives might improve enzymatic digestibility. The aim of this study was to examine the effect of NaOH and the boron derivatives sodium borohydride [NaBH4], calcined tincal [Na2B4O7(1-5)H2O], colemanite [CaB3O4(OH)3H2O], boron oxide [B2O3], borax decahydrate [Na2B4O710H2O], disodium octaborate tetrahydrate [Na2B8O134H2O] and boric acid [H3BO3] on enzymatic saccharification. Results showed that the boron derivatives prevented peeling reactions and preserved more glucan; however, the NaOH removed the highest amounts of xylan and lignin from the structure. Significant xylan removal was observed with H3BO3, while B2O3 was as effective as NaBH4 and NaOH for selective lignin removal. The highest enzymatic saccharification yield (59,5%) resulted with the 2% NaOH pretreatment, whereas slightly lower yields were achieved with some boron derivatives (1% NaBH4-45%; 2% B2O3-40,2%; and 2% H3BO3-36,7%).

Este artículo intenta explicar los criterios que sustentan la idea de que la contabilidad china ha sido conformada durante el pasado siglo con arreglo a factores culturales, económicos y políticos. Asimismo se propone estudiar los fenómenos históricos experimentados por la contabilidad china en el transcurso de los años, y evaluar comparativa y críticamente los efectos culturales de los mismos con las transformaciones políticas y económicas que han tenido influencia en el desarrollo de la contabilidad china. La sociología de la ciencia es el elemento determinante para analizar las transformaciones experimentadas por la contabilidad. Los factores políticos están referidos a factores culturales. En una primera época vinieron determinados bajo la presión del régimen comunista y de un gobierno de dirección central; en una segunda época se configuraron siguiendo el modelo de liberalización y de economía de mercado. El gobierno llamó a este modelo: “Política de puertas abiertas”. En los últimos años y en época reciente esta política ha conservado su influencia y ha forzado al gobierno chino a promulgar una nueva normativa contable en armonía con los principios contables internacionales. El sistema contable chino está ahora mucho más cerca de los “International Accounting Standards” de lo que estaban las prácticas del pasado; pero, a pesar de ello, conserva sus características y sus rasgos colectivistas y conservadores tradicionales. Los fundamentos culturales son los que sostienen e informan todavía el sector de la contabilidad china.

Muchos estudios recientes han afirmado que China integra en su sistema contable sus reglas tradicionales, sus intereses culturales y su estilo de vida. La “cultura” sería el punto dominante en su sistema contable. Hofstede, Gray, Mueller y otros investigadores empíricos de la contabilidad, que enfatizan la influencia de los efectos culturales en la configuración de los sistemas contables nacionales, sostienen que la Contabilidad China ha sido dominada por la “Cultura” China. Este trabajo presenta tres de entre las variables culturales chinas, a saber, Confucianismo, Feng Shui, Budismo, Yin-Yang, etc., que han marcado los comportamientos y las técnicas contables chinas. En China, el sistema contable se basó tradicionalmente en las prácticas confucianistas y en la antigua sabiduría; estos elementos todavía influyen en el sistema actual. En este artículo se estudian las influencias desde una perspectiva histórica en relación con las variables culturales chinas. Las influencias examinadas se centran en los metódos de la teneduría de libros, en las prácticas contables, en la información contable, etc. La evidencia suministrada por la literatura indica que, a pesar de los cambios en los regímenes de gobierno y en los estilos de gestión empresarial en China, las características principales de las influencias culturales sobre la contabilidad han sobrevivido. De este modo, la polaridad Yin-Yang todavía equilibra la contabilidad china. La lógica económica china se ha transformado para adaptarse a las prácticas de mercado, pero el misticismo chino ha mantenido su lógica en la República Popular China

ABSTRACT The objective of this study was to determine the sexual parameters in young bucks with different sexual activity and the effect of experience (age) on sexual parameters in bucks. Fifteen young, sexually inexperienced (SI) and five adult, sexually experienced (SE) Saanen × Hair goat crossbred bucks were used in this study. Bucks were individually exposed to three estrus does for 15-min periods during four sexual performance tests, which were carried out every other day to determine some sexual behavior traits such as flehmen response, reaction time, and ejaculation efficiency. Sexually inexperienced young bucks were evaluated based on their sexual activity (active (AC) vs inactive (IA)) and presence of horn. It was found that AC bucks had significantly higher serum testosterone concentrations (31.5 vs 21.5 ng/mL) and weight loss (114.2 vs 51.2 g/day) than IA bucks. In addition, weight loss was significantly correlated with ejaculation efficiency in young bucks. On the other hand, horned bucks tended to have higher ejaculation efficiency with significantly longer reaction time than polled bucks. For experience (age) classes, SE bucks had higher testosterone concentration (76.0 vs 31.5 ng/mL) and weight loss (16.7 vs 8.6%) than SI active young bucks. However, the effect of experience on other sexual performance traits was found to be limited. Overall, these results indicate that testosterone concentration may affect sexual performance of young bucks in the mating season. Age-related sexual experience is not a determining factor for sexual performance in bucks. However, sexual performance data alone may not reflect reproductive outcomes without semen data.

ABSTRACT The objective of this study was to determine the effect of supplemented organic selenium at different levels to concentrate feed of Norduz ewes in late pregnancy on maternal serum, placenta, colostrum, and offspring serum concentrations. This study was conducted using two-year-old 35 Norduz ewes. Ewes were randomly assigned to one of three dietary treatments for 57 days prepartum and at the seven days postpartum. Group 1 was fed a standard pregnant sheep concentrate basal diet without any additional Se supplement (control). Experiment groups were fed diets supplemented with 0.150 mg/kg, 0.300 mg/kg, and 0.450 mg/kg organic selenium to the same basal diet. Results showed that addition of selenium to gestating ewe diets increased Se in serum after one week of feeding. Ewes supplemented with 0.300 and 0.450 mg/kg Se had increased placenta, serum, and colostrum Se levels compared with those fed the control diet (P

Objectives: The aim of this study is to evaluate the efficacy, safety and postoperative outcomes of the recently developing endoscopic techniques of Bi-Vap (Richard Wolf®) saline vaporization of the prostate and bipolar plasmakinetic TURP in BPE over 90 ml. METHODS: In total, we included 147 patients treated with BiVap (Richard Wolf®) saline vaporization of the prostate (n=75) and bipolar plasmakinetic TURP(n=72). The inclusion criteria were Qmax ≤10 mL/s,IPSS ≥16, and prostate volume over 90 ml. Operation, hospitalization and catheter removal time were noted. Postoperative complications including urinary tract infection, transient hematuria, severe dysuria, and fever >38°C, urinary incontinence and urethral stricture were also noted. All patients were evaluated at the postoperative month 3. Preoperative and postoperative values of IPSS score, QoL score, IIEF-5, PVR, Qmax and Qave were compared. Statistical analyses were performed using SPSS 18.0 program and statistical significance was set at p<0.05., Results: The groups were similar with respect to preoperative age, height, weight, creatinine, PSA, prostate volume, IPSS score, Qmax, Qave, QoL score, PVR and IIEF-5 values. The mean operation time was significantly higher (<0.001) removal were significantly lower (0.001) compared to group 1. The groups were similar regarding at postoperative month 3 IPSS score, Qmax, Qave,QoL score, PVR and IIEF-5 values. The only exception was the rate of severe dysuria, which was significant lyhigher in group 2. CONCLUSION: Both BiVap (Richard Wolf®) saline vaporization of the prostate and bipolar plasmakinetic TURP are safe and highly effective minimal invasive techniques, which can be used in the surgical treatment of BPE over 90 ml. Although the longer operation time and higher rate of postoperative irritative symptoms, Bi-Vap (Richard Wolf®) saline vaporization of the prostate seems to be a potential alternative to other techniques with shorter length of stay and time to catheter removal.

Nicolau syndrome (NS) is a rare complication of intramuscular, intraarticular or subcutaneous injection of particular drugs leading to ischemic necrosis of the surrounding skin, soft tissue and muscular tissue. Benzathine penicilin one of the most widely used antibiotic for upper respiratory tract infections and has been rarely reported to cause NS. Here we describe a 4 year old boy with diagnosis of NS after the injection of benzathine penicillin who was successfuly treated with unfractionized heparin (enoxaparine) and pentoxifylline. The practitioners should pay attention for unnecessary use of benzathine penicillin to avoid from probable complications., (Sociedad Argentina de Pediatría.)
