Using a chemical spray technique, an n-type WO3 polycrystalline thin film was prepared with optimizing parameters (molarity concentration of 80 mM and a substrate temperature of 350 °C). Study the physical properties of WO3 thin film via UV-Visible spectroscopy, XRD, Field Emission-Scanning Electron Microscope, Energy Dispersive X-ray Spectroscopy, Atomic Force Microscopy, and current-voltage. Tungsten oxide was deposited on glass surfaces at different molarities ranging from 50–90mM. In the UV-Visible spectrum of the WO3 thin film, it was found that the transmittance, reflectivity, and energy gap decreased (78%–53%), (9.63%–5.02%), and (3.40eV–2.63 eV), respectively. The X-ray diffraction of the WO3 film at the optimized was poly-crystalline and had a monoclinic phase, and the preferred orientation (hkl) was 200 at 2 = 24.19. From the image FESEM and EDX, it was found that it has a multi-fibrous network. The average diameter of the fiber is 266 nm, and the ratio of tungsten to oxygen (W/O) is 2.6, with a stoichiometric of 68.6% at the 80 mM concentration. The Atomic Force Microscopy shows that the WO3 thin layer has a nanostructure. The average surface roughness was 5.3 nm, and the Root Mean Square was 8.6 nm. The WO3 film had the lowest resistivity value of 2.393 × 108W cm, and the activation energy was 0.298 eV, among the parameter of the current voltage at substrate temperature and concentration optimum.

REVERSE osmosis in saline water conversion ,SOLAR cells ,SOLAR energy ,REVERSE osmosis ,ENERGY consumption - Abstract
One of the most affordable and readily available energy sources is solar energy. Humanity is in danger due to the lack of freshwater. Finding novel approaches to these issues that make use of solar energy has grown in popularity as a research area. The previous work presented was made to cool solar cells to increase their performance. The reverse-osmosis system is then fed by the cooling water. This study investigated the ideal conditions for cooling water fed into a reverse-osmosis system. Two identical solar cells were used for the current experiments. Water was used to cool one of the two cells. Measurements were made of the cell surface temperature, output voltage, current, and power. It was calculated to find the electrical efficiency of both cooled and uncooled cells. The cooled cell produced a maximum power of 6.75 W, according to the results. At 1:00 p.m., the gain power reached its maximum. The greatest efficiency gain, 50.2%, was observed at 4:00 p.m. Throughout the work that was presented, there was an 8% decrease in cell surface temperature. The water application value engine (WAVE) was used to simulate a reverse-osmosis system. The program's findings demonstrated that energy consumption dropped as feed water temperature rose. The findings of a case study conducted in a real water-desalination plant were confirmed. [ABSTRACT FROM AUTHOR]

Objectives: To assess antibacterial effects of silver diamine fluoride (SDF) and fluoride varnish treatment against Streptococcus mutans and Lactobacillus acidophilus. Materials and Methods: The antibacterial effectiveness of SDF (group A) and fluoride varnish (group B) against S. mutans was investigated in an in vitro microbiological investigation, with distilled water (group C) serving as the positive and negative controls. After 24 hours of incubation, the antibacterial efficiency was assessed using the agar well diffusion technique, and the diameter of the zones of inhibition (ZOI) was quantified. Sumba mare's milk from MRS broth was extracted and then placed into a test tube. L. acidophilus was grown on Sumba mare's milk from MRS broth. On this media, each testing agent was poured and tested for the inhibitory zone. The obtained data was statistically analyzed. Results: SDF group had a higher mean zone of inhibition against S. mutans and Lactobacillus followed by fluoride varnish, and there was no ZOI in the case of distilled water. Intergroup comparison was significant. Conclusion: When compared to fluoride varnish, the SDF teeth remineralizing agent had greater antibacterial activity against S. mutans. [ABSTRACT FROM AUTHOR]

To prevent or reduce the drawback effect and prolong the life of PVC and preserve its composition and efficiency, compounds are incorporated with PVC. In this work, three highly aromatic anti-cancer Schiff base compounds in symbol (C2, C3 and C5) were applied to photostabilize of PVC against photodegradation, by added it to the polymer in the form of Schiff bases, to increase the stability of polymer when irradiated with ultraviolet (UV) light, (λmax = 365 nm) at 30 ºC, with the intensity of the light wavelength at 1920 lux for a long duration. The PVC was blended with Schiff's base in concentration (0.5 %wt.), with thickness films (40 μm) were made from the blended materials. Several methods were used, including infrared spectroscopy, surface examination of irradiated films to know the effect of additives on PVC photostabilization and conductivity of films were measured by LCR meter. The results showed that the additives significantly reduced the photodegradation of PVC. C2 compound as additive, stabilize PVC more than other additives, it can absorb harmful radiation, deactivate hydrogen chloride, and scavenge high-energy species such as peroxides. Several mechanisms of photostabilization for C2 compound have been suggested. Therefore it is acting as stabilizers for PVC. [ABSTRACT FROM AUTHOR]

This paper presents the development of a flexible wire bending machine designed to overcome limitations associated with traditional counterparts. Traditionally, wire bending machines are often designed for specific purposes, necessitate complex coding, are prohibitively expensive, or are constrained to producing two-dimensional shapes. To address these challenges, our study begins with an extensive review of existing research in the field, followed by the selection of a concept derived from this analysis. The methodology encompasses the entire design and manufacturing process. Initial research guides the concept selection, which is then translated into a practical design using SolidWorks simulations. The theoretical foundation involves mathematical formulations for each machine component, ranging from the wire feeding system to the bidirectional and 3D bending mechanisms. Main actuators are chosen based on calculated parameters, and the machine is assembled, incorporating a CNC system. The machine is tested first without wire and subsequently with the bending of an aluminum (1350-H26), 3.2 mm diameter wire, copper with 3.25 mm diameter and steel with 2.5 mm diameter. The results demonstrate high accuracy performance and underscore the significance of considering spring back and bend allowance for precision in both 2D and 3D wire configurations. This study not only contributes to the design and fabrication of a flexible wire bending machine but also addresses the shortcomings of traditional counterparts, making wire bending more accessible, versatile, and cost-effective.

The microbial polymeric biofilm matrix belongs to a single microbial species or multiple microbial species that are directly or indirectly responsible for over 80% of all microbial infections. A six-month laboratory study was conducted to extract the biofilms from Klebsiella pneumoniae and Candida albicans isolates to study their properties and their toxic effects on blood lymph. The results showed that treating 20 samples of K. pneumoniae and 100 samples of C. albicans biofilms with gentamicin and fluconazole antibiotics led to the inhibition of biofilm production for all the studied isolates by 74.9% and 64.32%, respectively. The results of screening electron microscopy (SEM) showed that the diameters of some K. pneumoniae cells ranged from 0.18-0.47 µm, while the diameters of C. albicans cells ranged from 121.82-133.89 nm. Fourier-Transform Infrared Spectroscopy (FTIR) of biofilmrevealed the presence of compounds in the matrix of the biofilm of K. pneumoniae, such as mannans and carboxylate (C=O), indicating the presence of sugar acids, proteins, and hydrocarbons. The results of the analysis of the biofilm produced by C. albicans showed a high percentage of sugars, as well as carboxyl and 2' acetyl. The Biofilm produced by K. pneumoniae inhibited the lymphocytes by 34.8% from the 150 μL sample. The lymphocytes showed higher inhibitory activity against C. albicans alone and against the combined biofilm of C. albicans and K. pneumoniae, where the highest percentage of inhibition reached 74.82% and 69.5% for the two treatments, respectively, at a sample volume of 100 µL. This leads to the conclusion that the biofilms of K. pneumoniae and C. albicans are responsible for over 80% of microbial infections. The use of antibiotics such as gentamicin and fluconazole led to the inhibition of biofilm production by up to 74.9% and 64.32% respectively, indicating the effectiveness of antibiotics in controlling biofilm growth.

The study sought to examine the impact of financial structure on the market value added of Iraqi tourism companies. The study adopted a quantitative approach by analyzing the financial data of a sample of Iraqi tourism companies for the period from 2004 to 2018. To measure the financial structure, three variables were used: Leverage Ratio, Equity to Total Assets Ratio and Short - Term Financing to Total Equity Ratio. The paper found that tourism companies differ in their reliance on debt in relation to property rights. It also found that there is a limited dependence of most of the study sample companies on fixed-cost loans in finance, in particular longterm loans. In addition, any improvement in the market value of the entity in relation to it carrying value will lead to an increase in the market value added. This study provides a better understanding of the relationship between financial structure in tourism companies and their market value added for researchers, practitioners and managers in the sector. Moreover, the results of this study are a working guide for financial managers in tourism companies and for the general investors in the tourism sector in determining the structure of financing or when making decisions to borrow or invest, because such decisions will directly affect the market value added of the company and the price of its shares in the financial markets. This study is one of the first studies that discuss the relationship of financial structure to market value added in the tourism sector in Iraq and is thus the starting point in exploring the determinants of financial structure in this important sector.

For urinalysis teaching and routine clinical imaging of urine, urine microscopic test needs slides that can be clearly examined for long term, which is still under focus. This study hypothesized, that poly(vinyl chloride) (PVC) and polystyrene (PS) could be able to reserve the urine components for a long time. Therefore, we explored, for the first time upon our knowledge, the potential of PVC and PS polymers to adhere the cover slide. The physical properties, viscosity, average molecular weight, the tensile strength and intrinsic viscosity of the polymers were determined. A normal slide (8 × 3 cm × 1 mm) was used to test a urine sample in the presence of either 3% PVC in tetra hydro‐furan(THF) or 3% PS. The results of imaging the PVC and PS slide indicate a clear and transparent vision. The PVC urine slide maintains normal components of urine up to a year, which did not observe in the PS slide. These results suggest that PVC is an effective polymer to protect urine compositions from hydrolyses or decomposition, which makes this novel urine slide a successful candidate for long‐term teaching of urinalyses.

- Abstract
Digital platforms are one of the educational resources that were used in education prior to Covid-19 pandemic. Nevertheless, the pandemic has led to a complete shift to learning via digital platforms, and therefore they have become a strategic alternative for sustainable education. Given that previous studies regarding the impact of digital platforms on learning outcomes have yielded conflicting results, the present study aims to determine whether or not digital platforms improve learning outcomes. To achieve this aim, meta-analysis approach was used through the examination of the overall effect size of these platforms on the learning outcomes besides the examination of the effect size of a set of mediating variables including study period, subject area, student rating, and publication type. Thirty studies published between 2015 and 2021 comparing learning via digital platforms and learning in traditional classrooms were accounted for. The focus on this period of time was because the fourth industrial revolution took place in that time where the use of digital platforms in teaching was prosperous. Findings showed that the overall effect size using the random effect model (g = 0.278; p < 0.001; α = 0.05) was small and positive, from (0.123–0.433) in favor of learning via digital platforms, and so no evidence regarding publication bias could be discovered in these data. The result of the current study may be useful to universities and e-learning centers on how to use digital platforms to improve learning outcomes. [ABSTRACT FROM AUTHOR]

The spread of COVID-19 has led to the closure of all educational institutions and a complete shift to distance learning using digital platforms, which succeeded in playing a major role in sustaining enhancement of educational goals during the crisis. Several studies have directed attention towards examining the factors that enhance the sustainability of digital platforms in enhancing learning outcomes during the pandemic, whether through technological or educational design elements or through the integrative design of all platform tools and educational strategies. Accordingly, the current study was proposed with the aim of identifying the role of digital platforms in improving learning outcomes during the pandemic, and thus the sustainability of learning, through a systematic review of several qualitative and quantitative studies conducted on digital platforms during the crisis. The systematic review was based on twenty three studies, which divide as seventeen studies devoted to studying the efficiency of technological and educational design elements, and six studies for dealing with the efficiency of the integrated design of digital platforms in enhancing learning outcomes. The results have demonstrated the role of some digital platforms such as Moodle, Google classroom, Microsoft Teams, Edx, Canavas, Teachsus, and CCtalk in achieving sustainable learning during the pandemic. However, the most important learning outcomes that were enhanced are knowledge, satisfaction, interaction, participation, and higher-order thinking skills, and performance skills, motivation, in addition to attitudes, perceptions, communication skills, and self-efficacy. The technological design elements that were based on gamification variables, flipped classes and mini video also were shown to have a role in enhancing the learning outcomes. The educational elements that were based on problem-based learning, cooperative learning activities, discovery learning, integrating synchronous and asynchronous learning, and formative assessment were shown to have a significant role in enhancing learning outcomes.

- Abstract
Although the economic value of glass products and its importance to the Saudi National Economy is vast, not much information is available about the current state of the art of the industry. Likewise, little information is available about geography, potential sites for mining sand and the sand quality. This paper attempts to bridge this gap by presenting a feasibility study of fabricating normal glass and glass ceramics from Saudi Arabia's domestically available raw materials. It discusses the current status of the glass industry in Saudi Arabia and the Middle East region. It also gives a brief explanation about the sand topography in Saudi Arabia. In order to determine the feasibility of fabricating glass using these raw materials, experimental data on the fabrication of normal glass and glass ceramics from indigenously available raw materials was obtained and reported as part of the findings of this paper. Firstly, normal transparent glass was able to be fabricated without any apparent large defects using sand collected from the Ar Rayis region in Saudi Arabia. Four nano-sized crystallization catalysts, namely VC, WC, TiC and Y
2 O3 , were added to the constituents of the glass in 3 wt.%. For VC, the crystallization process was limited. The glass ceramics of WC consisted of multi-dimensional edges crystals which covered all the matrix. Gray crystalline whiskers were obtained by addition of TiC. The Y2 O3 - glass ceramics consisted of multi-directionally rosette crystals. Finally, the microhardness values of the added crystallization catalysts glass ceramics were obtained and found to be much higher compared to normal glass. The results show that glass of high quality can be produced specifically for the Ar Rayis region which would be of interest to researchers, the glass industry personnel and potential investors.

- Abstract
Gamified platforms have a great role in motivating students to proceed with enthusiasm in learning events and activities. The COVID-19 pandemic has generated some tensions and pressures that were reflected on students’ engagement in learning when studying through digital platforms. Accordingly, this research examines the impact of using gamified platforms on engagement in learning during the COVID- 19 pandemic. The quasi-experimental approach was used to compare the first experimental group that used the G1-Gamified platforms and the second experimental group that used the same platform but not gamified and was referred to as G2-Non-gamified platforms. The research sample in the quantitative study consisted of 60 students from the tenth grade in Jeddah, who were randomly distributed to the two research groups. A measure of engagement in learning has been developed and consisted of three themes with a total of 24 items. The results showed the preference of the first experimental group, which used gaming platforms, in improving indicators of engagement in learning through educational platforms during the pandemic. The research recommended the need to employ digital incentives such as points, badges, levels, and leaderboards in digital platforms to increase the effectiveness of these platforms in improving learning outcomes.

Aim: To digitally evaluate the marginal adaptation of different types of all‐ceramic crowns on two different marginal configurations such as Shoulder and Chamfer of the prepared teeth. Methods: The marginal fit of the crown specimens on the model of the prepared teeth were assessed using the dual scan replica technique. Two plastic teeth were prepared; one having a Shoulder finishing line (A), while the other with a Chamfer finish line (B). Three types of different all‐ceramic crowns, layered zirconia, monolithic zirconia, and pressed lithium disilicate, were fabricated for each prepared tooth (A) and (B). Measurements for assessing the marginal discrepancy were done on four designated points on the mesial, distal, buccal, and palatal surface of the superimposed image. Results: The average marginal gap was the largest in the layered zirconia group, followed by monolithic zirconia, while pressed lithium disilicate crowns showed the least marginal gaps. Crowns with Chamfer finish lines were better fitting (less marginal gap) than the shoulder finish lines across all the groups. Conclusions: Chamfer finish lines produced better fitting restorations, and heat‐pressed lithium disilicate crowns showed better adaptation at the margins than both layered zirconia and monolithic zirconia.

Objectives: To build a lamotrigine (LTG) physiologically based pharmacokinetic (PBPK) model (LTG PBPK) and compare it to the clinical data from South Asian Indian patients and use this model to understand the drug interactions of LTG and explore the optimal doses. Methods and Material: The PBPK model was developed using the PK-Sim software platform and qualified with LTG plasma concentration data from an Indian study. The European population database was chosen as the patient setting in the software. Physiochemical data of LTG and enzyme kinetic data were incorporated from the literature. Dosing protocols were as per the previous study. Interaction models for drug interactions with carbamazepine and valproate were also simulated. Results: Most of the model predicted concentration-time profiles of LTG at steady-state were well within the observed concentrations. The developed models were suitably qualified. The drug interaction model was used to assess the impact of induction and inhibition of the pharmacokinetic profile of LTG. Conclusions: The predicted plasma concentrations of the developed PBPK models using the European population database were very similar to the data from Indian patients. The developed LTG PBPK models are applicable in predicting the impact of drug interactions and can yield appropriate LTG doses to be administered. [ABSTRACT FROM AUTHOR]

Background. Dental professional's competency comprises a comprehensive management of the oral health care of their patients, and an evaluation of competence level is an important step towards assessing the quality of the graduating dentists. This study assessed the level of self-rated competencies of dental graduates from Saudi dental colleges. Methods. A cross-sectional study was conducted online through a structured questionnaire that consisted of three domains of "Knowledge, Skills, and Values." The study population was dental graduates who have studied the same curriculum and were working in Saudi dental settings. Dental graduates included interns, general practitioners, and specialists/consultants, both male and female, grouped into age groups (20-24, 25-29, and ≥30 years), Saudi/non-Saudi, with qualifications (Bachelor, Master, and Fellowship/Board), working in any region inside Saudi Arabia. Results. Complete responses received from 197 graduates were analyzed. ≥75% of the respondents felt that they were well prepared for 40% and half of the respondents felt that they were not well prepared in 50% competencies in the domain of "Knowledge." ≥75% of the respondents felt that they were well prepared for 36% and 50% were not well prepared in 36% competencies in the domain of "Skills." ≥75% of the respondents felt that they were well prepared for 67% competencies in the domain of "Values." Statistically, mean values were significant (p ≤ 0.001) for female genders and nonsignificant for qualification and rank categories. The overall mean scores for self-perceived competencies for the domains of "Knowledge," "Skills," and "Values" were 8.9 ± 3.1 , 12.8 ± 3.3 , and 5.5 ± 2.1 , respectively. Participants showed the highest level of "Knowledge" in medical problem diagnosis and least level in basic life support. The highest level of "Skills" was noted in the differential diagnosis and lowest in the dental emergency management. Most participants had shown a value for service to humanity. Conclusions. Dental graduates of this study sample perceived themselves well prepared for many aspects of dental practice and have highlighted areas that need improvement in their training at the undergraduate level.

The relationship between Zn and Cd uptake by plants is somewhat controversial according to the lack of information about this subject. The objective of this study was to increase our scientific understanding of soil about plant factors controlling Zn and Cd bioavailability and uptake. This experiment was carried out in the winter season of 2019. It aimed to solve the mystery of the Zn and Cd relationship in soil and plant uptake. Five plant species were under observation (carrot – Daucus carota, radish – Raphanus sativus, wheat – Triticum aestivum L., lettuce – Lactuca sativa and bean – Vicia faba). Plants were planted in plastic pots containing 2 kg sandy loam soil with duplicate and exposure to six Zn:Cd ratios (1:0.5, 1:1, 2:1, 3:1, 4:1 and 5:1) with increasing elements molar ratio of Zn to Cd in soil. After 45 days, plants were harvested. Zn and Cd were determined in roots and shoots. Results showed, that at low molar ratios of Zn:Cd in soil, the relationship between these metals in soil is almost synergistic and both elements are accumulated easily in plant tissues, but at high molar ratios, the relationship between these metals is almost antagonistic where Cd be more competitive to Zn uptake by plants. It was concluded that the 2:1 Zn:Cd ratio in the soil is the border between synergistic and antagonistic relationships. [ABSTRACT FROM AUTHOR]

The climatic conditions, global environmental crises and disasters and the exacerbation of the pollution problem have prompted global economic and financial organizations such as the International Monetary Fund, the World Bank and the Organization for Economic Cooperation and Development to reconsider traditional economic models, Which resulted from it the emergence of the concept of green economy. Which made the economy more efficient by increasing the productivity of used resources and directing investments towards sustainable management of natural resources to increase their economic and environmental productivity and their ability to create green jobs and support the poor to the maximum extent possible. Because of the modernity of this economy, developing countries requested not to impose a single model that includes developed and developing economies at the United Nations Conference (Rio + 20) held in the Brazilian capital, Rio de Janeiro in 2012, and the necessity to create a broad concept for a green economy that is flexible and takes into account the disparity in levels of economic development and transformation policies Towards a green economy. Many scientific studies have proven that the development of the relationship between man and the environment was characterized by an increase and an imbalance between environmental degradation and human progress. The earth, with all its surrounding organisms, is the natural home of man who gets it, and many studies and research revealed that the environments in which a person lives can be It causes an increase or decrease in stress on his body, as the uncomfortable environment causes feelings of anxiety or sadness in contrast to a comfortable environment, and a person finds pleasure in nature regardless of his age or culture, and more than two-thirds of people choose to be in a natural environment to get rid of psychological pressure and cure many diseases Psychological and physical. The research aims to activate the role of the green economy in achieving sustainable develop ment and focus on the health aspect. To achieve the aim of the study, the descriptive and analytical approach was used to study the reality of the trend towards a green economy in Iraq and its role in achieving development. A quantitative approach is used to analyze and interpret the impact of the green economy on sustainable development. And through the benchmarks, it was found that there is a relationship between the sustainable development indicators and the green economy index. [ABSTRACT FROM AUTHOR]

LINEAR algebra , *MAGMAS , *APPLICATION program interfaces , *PROCESS optimization , *MATHEMATICS - Abstract
With the acquisition and widespread use of more resources that rely on accelerator/wide vector–based computing, there has been a strong demand for science and engineering applications to take advantage of these latest assets. This, however, has been extremely challenging due to the diversity of systems to support their extreme concurrency, complex memory hierarchies, costly data movement, and heterogeneous node architectures. To address these challenges, we design a programming model and describe its ease of use in the development of a new MAGMA Templates library that delivers high-performance scalable linear algebra portable on current and emerging architectures. MAGMA Templates derives its performance and portability by (1) building on existing state-of-the-art linear algebra libraries, like MAGMA, SLATE, Trilinos, and vendor-optimized math libraries, and (2) providing access (seamlessly to the users) to the latest algorithms and architecture-specific optimizations through a single, easy-to-use C++-based API.

Short tandem repeat (STR) markers are highly being used for identification of human being in addition to paternity and other forensic cases. The X-chromosome STR (X-STR) markers are a powerful supplementary system particularly in deficiency paternity analysis. Several X-linked microsatellites have been assessed but more studies are necessary to verify the population statistics. In our study, we report allele frequencies of 13 X-linked microsatellites (DXS8378, DXS9898, DXS8377, HPRTB, GATA172DO5, DXS7423, DXS6809, DXS7132, DXS101, DXS6789, DXS9902, DXS6807, and DXS7424) in the Iraqi arab population. fifty Blood samples were collected from healthy unrelated males. A total number of alleles were detected for for all 13 X-STR loci were (83) and the related frequencies ranging from 0.0200 to 0.5000. Heterozygosity ranged from 0.652 to 0.858. Large values were observed, at least 0.999999994, in combined powers of discrimination. The results powerfully suggest that all the X-linked microsatellites defined here can possibly support the autosomal systems that used in parentage analysis and different forensic case work.

Cases of deficiency paternity, characterized by missing of the alleged father, are a task for forensic genetics. Recently these cases were determined using sets of extremely polymorphic autosomal short tandem repeats (STRs), which indicate to powerful likelihood ratios (LR). Some difficult cases emerge whenever the kinship highly remote or if the another hypotheses are not properly formulated because of the absence of information. In these situations, beyond the routinely used marker set, laboratories usually enlarge the number and/or the type of markers analysed. A set of 14X-STRs is further advantageous than 21 autosomal STRs (AS STRs) biallelic markers. Furthermore, the utility of X-STRs was also appear in cases shows that in father-daughter duos and merely a close family member of the alleged parent (father or mother) is existing for testing. Here we present a cases with biological daughter of the alleged father and her mothers and putative grandmother was the genotyped relative are available for reconstructing his haplotype. Aiming to increase the Paternity Index (PI), Probability of Paternity (PP), and obtain more reliable results. The result of X STR showed that the missing person (father) share 50% genotype with the donors (daughter)and (his mother) at each locus, there are no alleles in any one of these 13 loci conflict with the alleles inherited from her father and Posterior Probability of paternity was (99.999958%) that is mean the missing person was biological father for this donor daughter.

Introduction: Pulmonary aspergillosis is the main respiratory fungal infection however; its diagnosis is missed or delayed in critically ill non‐neutropenic patients. Despite the utility of fiberoptic bronchoscopy for the evaluation of tracheobronchial aspergillosis (TBA) in immunocompromised patients has been extensively studied, however its utility in critically ill non‐neutropenic patients is underestimated. Objectives: To assess the bronchoscopic changes suspected TBA relative to the microbiological and histopathological aspects in critically ill non‐neutropenic patients admitted to respiratory intensive care unit (RICU). Methods: We prospectively studied 139 critically ill non‐neutropenic patients admitted to RICU and had a clinical suspicion of broncho‐pulmonary Aspergillus infection. Those patients were subjected to clinical and bronchoscopic assessment for the evaluation of suspected TBA. Microbiological culture of bronchoalveolar lavage (BAL) and histopathological examination of tracheobronchial biopsies were done. Results: Bronchoscopic changes suspected TBA were found in 48.2% of patients (67/139), where Aspergillus infection was confirmed microbiologically in 59.7% (40/67) and histopathologically in 56.7% (38/67). Of these changes, whitish plaques ± ulcers, pseudomembrane and/or sticky secretion with hyperemic mucosa were detected in 68.7%, 26.9% and 16.4% respectively. These changes were mostly seen in the main bronchi (54/67; 80.6%). The sensitivity, specificity, positive, negative predictive values and overall accuracy of these bronchoscopic changes as compared with BAL fluid results were 83.3%, 70.3%, 53.2%, 91.2% and 74.1% respectively. Conclusions: Bronchoscopy could be a reliable procedure for TBA diagnosis in critically ill non‐neutropenic patients. Whitish plaques ± ulcers were the prominent bronchoscopic changes with reasonable diagnostic accuracy for prediction of TBA. [ABSTRACT FROM AUTHOR]

ntroduction: Asthma attacks all age groups but often starts in childhood. Asthma is a chronic disease characterized by recurrent attacks of breathlessness and wheezing, and occurs in people of all ages. It is the most common chronic disease among children. Many publications have shown an association between severity of asthma symptoms and obesity in children and adults. The aim of the study is to assess the symptoms of asthma and the relationship to obesity among secondary school students in Fallujah City. Method: A cross-sectional study was done during March 2018. We assessed 47 students with asthma from nine secondary schools across Fallujah city, Anbar governorate, Iraq. Simple random sampling technique has been used to select the nine schools. Results: With a total of 47 subjects with asthma, 20 (42%) male and 27 (57.4%) female subjects have been included in the study. The age of subjects was between (15-23 years with mean 17 ±1.8). With a total of 47 participants with asthma, 33 (70.2%) participants had attacks of cough or wheeze more than a couple of times per week in the last month. The corresponding weight categories of those 33 participants were as follows: six were obese, nine of over-weight,14 were normal-weight and four of under-weight. Those who had attacks of cough or wheeze less than a couple of times per week in the last month were 14 (29.8%) participants and their corresponding weight class were: None of them were obese, four were overweight, eight of normal-weight and two were under-weight. Conclusion: Obesity could be a risk factor for severe asthma symptoms among the subjects. Recommendation: Further national study is needed for assessment the association between obesity and severity of asthma symptoms among students in secondary schools. [ABSTRACT FROM AUTHOR]

Research aims: This study examines the relationship between total quality management (TQM), the role of the management accountant and organisational performance among the service sector in Malaysia. Design/Methodology/Approach: This study collects data from 100 private service organisations in Malaysia via a self-administered printed questionnaire. Data collected are analysed using partial least squares (PLS) 3.0. Research findings: The results reveal that TQM has a positive significant impact on organisational performance. The TQM's practice of focussing more on customers and the designing of services also show significant effects on organisational performance. This study finds that management accountants do not moderate the relationship between TQM and organisational performance. Theoretical contribution/Originality: This study expands the previous literature by examining the role of the management accountant as a moderator between TQM and organisational performance. Practitioner/Policy implications: The results derived from this study can be used to facilitate the application of TQM in service organisations so as to enhance their organisational performance. The findings can also assist managers in the service organisations to determine the functions of their management accountants because this can impact on the successful adoption of TQM. Research limitation/Implications: The limitations of this study includes its scope which is confined to only the service industry. Future research should expand further to cover other industries.
