The use of a sprinkler irrigation system is becoming more popular to reduce water
consumption and increase irrigation efficiency. Irrigation uniformity plays an important role in the
performance of the sprinkler irrigation system. The use of low operating pressure instead of high
operating pressure system offer many benefits including energy and water saving. An experimental
study was performed using two systems; a square 12x12 m system and a rectangular 10x12 m system
to investigate irrigation uniformity based on soil moisture content of the sprinkler irrigation system
under low operating pressure. In addition, irrigation uniformity was compared based on water
application and soil moisture content. In this study, different low operating pressures (62, 82, 102 and
122 KPa) were selected. Different nozzle diameters (4, 5, 6 and 7 mm) and different riser heights (0.5,
0.75, and 1.0 m) were also used. The soil moisture content uniformities of 10 min after irrigation are
more dependent on the initial soil moisture content uniformity than any other design factor. It is also
less influenced by water application uniformity.

Thermophotovoltaic conversion using heat to generate electricity in photovoltaic cells based on the detraction of thermal radiation suffers from many engineering challenges. The focus of this paper is to study the nanostructure of AlGaAsSb for thermophotovoltaic energy conversion using lattice-matched heterostructures of GaSb-based materials in order to overcome the current challenges. The XAFS spectroscopy technique was used to analyze electronic structures and optical properties of GaSb, (Al, In) GaSbAs. The XAFS spectroscopy analysis showed a powerful decay at peak intensity that reveals to be related to a loss in Sb amount and light As atoms replaced in Sb atoms by 25%. Moreover, it was found that Al/In doped samples have highly symmetric data features (same atomic species substitution). The narrow direct bandgap energy, Eg of Al0.125Ga0.875Sb0.75As0.25 material raised (0.4-0.6 eV) compared to conventional photovoltaic cell bandgap energy (which is generally less than 0.4 eV) with weak absorption coefficients. The thermoelectric properties of AlGaAsSb computed via Botlztrap code showed that the electrons made up the majority of the charge carriers in AlGaAsSb. This nanostructure material exhibited a higher and acceptable figure of merit and demonstrated a promising thermoelectric material for solar thermophotovoltaic applications.

Arch Med Sci, 2014 May 12;10(2):294-9.
PMID: 24904663 DOI: 10.5114/aoms.2012.31297

Coeliac disease (CD) is a common diagnosis among children and adults in Iraq; however, removal of gluten from the diet is essential for patients with CD. The aim of this study, the first such study in Iraq, was to assess the serological and histological recovery profiles of coeliac patients, in both children and adults groups after commencing a gluten-free diet (GFD) for at least 1 year ± 1 month.
Fulltext Simple and rapid molecular techniques for identification of amylose levels in rice varieties

Cheng A, Ismail I, Osman M, Hashim H

Int J Mol Sci, 2012;13(5):6156-66.
PMID: 22754356 DOI: 10.3390/ijms13056156

The polymorphisms of Waxy (Wx) microsatellite and G-T single-nucleotide polymorphism (SNP) in the Wx gene region were analyzed using simplified techniques in fifteen rice varieties. A rapid and reliable electrophoresis method, MetaPhor agarose gel electrophoresis (MAGE), was effectively employed as an alternative to polyacrylamide gel electrophoresis (PAGE) for separating Wx microsatellite alleles. The amplified products containing the Wx microsatellite ranged from 100 to 130 bp in length. Five Wx microsatellite alleles, namely (CT)(10), (CT)(11), (CT)(16), (CT)(17), and (CT)(18) were identified. Of these, (CT)(11) and (CT)(17) were the predominant classes among the tested varieties. All varieties with an apparent amylose content higher than 24% were associated with the shorter repeat alleles; (CT)(10) and (CT)(11), while varieties with 24% or less amylose were associated with the longer repeat alleles. All varieties with intermediate and high amylose content had the sequence AGGTATA at the 5'-leader intron splice site, while varieties with low amylose content had the sequence AGTTATA. The G-T polymorphism was further verified by the PCR-AccI cleaved amplified polymorphic sequence (CAPS) method, in which only genotypes containing the AGGTATA sequence were cleaved by AccI. Hence, varieties with desirable amylose levels can be developed rapidly using the Wx microsatellite and G-T SNP, along with MAGE.

J Environ Public Health, 2019;2019:9896410.
PMID: 31061664 DOI: 10.1155/2019/9896410

Background: Heat stress disorders may cause negative health outcome and subsequent productivity reduction especially in those who work under direct sunlight for an extended number of hours.
Objective: This study assessed the impact of heat on the health and productivity among maize farmers in a hot tropical country.
Methods: A cross-sectional study was conducted among 396 maize farmers, randomly selected across Gombe province, Nigeria. The wet bulb globe temperature monitor (WBGT) Model QuesTemp036 was used in determining the heat index. Health was determined using a validated questionnaire, while productivity was determined by recording work output based on the number of ridges cultivated during the working hours.
Results: The farms recorded mean heat index with standard deviation (SD) of 31.56 (2.19) and 34.08 (1.54) in the hours of 9 am to 12 pm and 12-3 pm respectively, which exceeded the threshold level set by the ACGIH. Heavy sweating (93.2%), tiredness (48.5%), dizziness (34.1%), and headache (40.4%) were experienced by the respondents almost on daily basis. The finding further showed a significant difference in the farmers' productivity during the three time duration of the work day (p < 0.001). The productivity was significantly higher between the hours of 6-9 am (p < 0.001) and 12-3 pm (p < 0.001), compared to the hours of 9 am to 12 pm (p < 0.001). The factors that significantly predict the productivity outcome include temperature (p < 0.001), gender (p < 0.001), age (p=0.033), and BMI (p=0.008).
Conclusion: The farmers were frequently experiencing heat exhaustion which decreased their productivity.

PMID: 35089947 DOI: 10.1371/journal.pone.0262313

OBJECTIVES: This study is designed to determine the knowledge, attitude, and practice of food poisoning and its factors among postgraduate students in Universiti Putra Malaysia.
METHODS: A cross-sectional study was conducted among 212 respondents who were selected through simple random sampling. Data was generated using a validated and reliable self-administered questionnaire.
RESULTS: The majority of the respondents are male, aged less than 35 years old, non-Malaysian, single, first-degree holders, not working, received a monthly income of less than 3264 Malaysian Ringgit, aware of food poisoning outbreak and the sources of their information of the food poisoning outbreak were television, the internet, newspaper, Online journals, friends, Facebook, community, nurse, drinking raw milk for the second time, information from their parents, relatives, restaurant, and radio. Majority had previous history of food poisoning illness but didn't correctly confirm the causes of their food poisoning illness. Majority had poor knowledge, acceptable attitude, and good practice of food poisoning. A significant association was observed for citizen, marital status, awareness of food poisoning outbreak, and previous history of food poisoning illness with knowledge. Gender and awareness of food poisoning outbreak were significantly associated with attitude. Attitude and practice were significantly associated. Logistic regression revealed that being married, awareness of food poisoning outbreak, and previous history of food poisoning illness are predictors for good knowledge. Female respondents and awareness of food poisoning outbreak are predictors for acceptable attitude.
CONCLUSION: Documentation of the identified poor knowledge and factors affecting knowledge, attitude, and practice provides essential information on the baseline indicators towards the risk of food poisoning among the respondents. A relevant interventional program is highly recommended to prevent the potential risks of food poisoning outbreak among them.

PMID: 24470797 DOI: 10.1155/2013/940201

Stevia rebaudiana Bertoni is a member of Compositae family. Stevia plant has zero calorie content and its leaves are estimated to be 300 times sweeter than sugar. This plant is believed to be the most ideal substitute for sugar and important to assist in medicinal value especially for diabetic patients. In this study, microcutting techniques using a mist-chamber propagation box were used as it was beneficial for propagation of Stevia and gave genetic uniformity to the plant. The effects of different treatments on root stimulation of Stevia in microcuttings technique were evaluated. Treatments studied were different sizes of shoot cuttings, plant growth regulators, lights, and shades. Data logger was used to record the mean value of humidity (>90% RH), light intensity (673-2045 lx), and temperature (28.6-30.1°C) inside the mist-chamber propagation box. From analysis of variance, there were significant differences between varieties and treatments in parameters studied (P < 0.05). For the size of shoot cuttings treatment, 6 nodes cuttings were observed to increase root number. As compared to control, shoot cuttings treated with indole butyric acid (IBA) had better performance regarding root length. Yellow light and 50% shade treatments showed higher root and leaf number and these conditions can be considered as crucial for potential propagation of Stevia.
Fulltext Neonatal intestinal obstruction secondary to a floppy Meckel's diverticulum successfully treated by minimal access surgery

Aziz DA, Sehat SI, Osman M, Zaki FM

BMJ Case Rep, 2012;2012.
PMID: 23242081 DOI: 10.1136/bcr-2012-006956

Meckel's diverticulum has several known complications including diverticulitis and perforation. The presence of mesodiverticular band or a band from the diverticulum to the anterior abdominal wall is also described and can cause obstruction or rotation of the small bowel leading to volvulus. Meckel's diverticulum is also well known as the lead point for intussusception. It may be lined by ectopic gastric mucosa and can cause life-threatening gastrointestinal bleeding. We report a neonate who presented with acute intestinal obstruction secondary to a large, mobile Meckel's diverticulum which due to a direct compression effect on the adjacent small bowel caused mechanical intestinal obstruction. Diagnosis was confirmed at laparoscopy, and treated by curative surgical resection. This is the first report of a large mobile Meckel's diverticulum causing small bowel obstruction due to direct compression that was managed by minimally invasive surgical resection.

Relationships between Media Exposure and Knowledge, Attitude, and Practice on HIV/AIDS: A Cross Sectional Survey of Adolescent Islamiyya Girls in Nigeria

Muhammad Hamid A, Tamam E, Nizam Bin Osman M

Health Commun, 2020 04;35(4):419-429.

Exposure to HIV/AIDS media among adolescents in sub-Saharan Africa was reported as low in the early 2000s, but now given developments in technology and program appeal, there emerges a need for reassessment. Given that communication, particularly through the media plays a major role in stemming the spread of the epidemic, this study examines the HIV/AIDS media exposure, knowledge, attitude, and practice (KAP) of adolescent Islamiyya girls in northern Nigeria as a predominantly Muslim society. The objectives of the study were to (1) identify the girls' major sources of information on HIV/AIDS; (2) assess their exposure to HIV/AIDS media and their HIV/AIDS knowledge, attitude and practice; and (3) verify relationships between media exposure and HIV/AIDS KAP. Based on the Advertising Research Foundation's Hierarchy of Effects model, hypotheses were posed to test the relationships. A questionnaire survey was administered on a randomly selected sample of 500 Islamiyya girls in Bauchi, Nigeria, from an estimated population of 35,000. Results were analyzed using descriptive statistics and partial least squares structural equation modeling. The results showed media exposure is not a significant predictor of HIV/AIDS practice, but it is a significant predictor of HIV/AIDS knowledge. And HIV/AIDS knowledge significantly predicted both HIV/AIDS attitude and practice. HIV/AIDS attitude also significantly predicted HIV/AIDS practice. It is thus concluded that among Nigerian adolescent girls, exposure to HIV/AIDS media is a necessary but not a sufficient predictor of HIV/AIDS KAP.

Diabetes mellitus contributes to male sexual dysfunction and infertility by modulating oxidative damage. To date, a number of studies have demonstrated antioxidant properties of Hibiscus sabdariffa Linn. This study was designed to investigate the effects of H. sabdariffa UKMR-2 variety on sperm functioning of streptozotocin-induced diabetic rats. Male Sprague-Dawley rats were allotted into four groups, namely control group (C), H. sabdariffa extract (HSE) group, diabetes group (D) and diabetes plus HSE group (D+HSE). HSE (100 mg/ kg/body weight) was administered orally for 28 consecutive days. After 28-days of supplementation, the rats were sacrificed to obtain epididymal sperm. Administration of HSE significantly lowered the level of fasting blood glucose and increased plasma insulin level in D+HSE group as compared to D group (p<0.05). Sperm quality in the D+HSE group was improved with significantly higher sperm concentrations (p<0.05) and sperm motility (p<0.001) as well as lower percentage of sperm abnormality (p<0.05) as compared to the diabetic group. Plasma follicle-stimulating hormone (FSH) level was significantly elevated (p<0.05) in D+HSE group than in D group while no significant alteration in plasma testosterone and luteinizing hormone (LH) level were seen between groups. In conclusion, this study suggested that H. sabdariffa UKMR-2 variety has a potential protective role against diabetes-induced sperm damage.

Int J Lab Hematol, 2019 Jun;41(3):418-423.
PMID: 30938931 DOI: 10.1111/ijlh.13009

INTRODUCTION: Haemoglobin (Hb) levels are used to assess eligibility for blood donation but are not correlated with iron status. The percentage of hypochromic red cells (%Hypo-He) has been suggested as a useful screening parameter for iron deficiency. The aim of this study was to determine the cut-off level and accuracy of %Hypo-He screening among blood donors.
MATERIALS AND METHODS: A total of 170 blood donors were recruited into the study. Blood donors were classified into three groups: normal, latent iron deficiency and iron deficiency anaemia based on their Hb, serum ferritin and transferrin saturation (TSAT) levels. The diagnostic performance of %Hypo-He was evaluated with a validation group comprising 160 blood donors.
RESULTS: Receiver operating characteristic (ROC) curve analysis showed that %Hypo-He is an excellent parameter for detecting iron deficiency, with an area under the curve (AUC) of 0.906, a confidence interval (CI) of 0.854-0.957 at a cut-off of 0.6%, and 74.51% sensitivity and 88.24% specificity. A moderate negative correlation between %Hypo-He and TSAT (ρ = -0.576 [P
Allicin has significant effect on autoimmune anti-islet cell antibodies in type 1 diabetic rats

Osman M, Adnan A, Salmah Bakar N, Alashkham F

Pol J Pathol, 2012 Dec;63(4):248-54.
PMID: 23359194 DOI: 10.5114/pjp.2012.32772

The research purpose was to experimentally investigate the effect of allicin administration on the levels of main type 1 diabetes (IDDM) autoantibodies which are anti-islet cell antibodies (ICA) with an attempt to find a relation between this immunological effect and histological and/or biochemical findings. We have evaluated, with the help of ELISA kits, the levels of ICA and serum insulin in male Sprague-Dawley rats with Streptozotocin-induced IDDM in addition to pancreatic histological findings. The four groups (6 rats each) under study received or not different intraperitoneal doses of allicin for a period of 30 days. Daily intraperitoneal administration of allicin (either at as low dose of 8 mg/kg or high dose of 16 mg/kg) for up to 30 days to type 1 diabetic rats effectively reduces levels of anti-islet cell antibodies and in addition, reduced the level of insulin due to damaged Langerhans islet cell was significantly increased in the serum due to a repairing tissue process in pancreatic tissues. These experimental results suggest that allicin treatment has a therapeutic protective effect against autoimmune reactions occurring in IDDM. The data may provide new strategies for using allicin to be recommended as an excellent candidate in the clinical management, control, and prevention of IDDM.

PMID: 28813631 DOI: 10.1139/gen-2017-0100

While it is crucial for developing countries like Malaysia to achieve self-sufficiency in rice (Oryza sativa L.), it is equally critical to be able to produce high-quality rice, specifically fragrant rice, which demands are often met through importation. The present study was aimed at developing high-yielding fragrant rice, in a timely and cost-effective manner. A marker-assisted backcross (MABC) approach was optimised to introgress the fragrance gene (fgr) into two high-yielding Malaysian varieties, MR84 and MR219, within two years utilising less than 50 molecular markers. Coupled with phenotypic screening, one single foreground marker (fgr-SNP) and 48 background markers were selected and utilised, revealing recovery of at least 90% of recurrent parent genome (RPG) in merely two backcross generations. Collectively, the yield potential of the developed BC2F2 lines (BLs) was higher (P > 0.05) than the donor parent, MRQ74, and similar (P < 0.05) to both the recurrent parents, MR84 and MR219. In addition, some of the developed BLs showed good grain quality, such as having long grain. We believe that this is the first report comprising the validation and utilisation of the single functional marker system (fgr-SNP) in introgressing the fgr gene into different rice varieties.

PMID: 31453284 DOI: 10.1016/j.dib.2019.104266

This paper provided spectroscopic data that is relevant with research article entitled "Synthesis and structural characterization of 6-(N-methyl-pyridin-2-ylcarbamoyl)-pyridine-2-carboxylic acid methyl ester Isomer" (Kadir et al., 2017) [1]. From the reported study, four new ligand of monoamide isomers were successfully synthesized using acyl chloride methods. The monoamide compounds namely 6-(3-methyl-pyridin-2-ylcarbamoyl)-pyridine-2-carboxylic acid methyl ester (L1), 6-(4-methyl-pyridin-2-ylcarbamoyl)-pyridine-2-carboxylic acid methyl ester (L2), 6-(5-methyl-pyridin-2-ylcarbamoyl)-pyridine-2-carboxylic acid methyl ester (L3) and 6-(6-methyl-pyridin-2-ylcarbamoyl)-pyridine-2-carboxylic acid methyl ester (L4) were fully characterized by Fourier Transform Infrared (FTIR), 1H Nuclear Magnetic Resonance (1H NMR) and 13C Nuclear Magnetic Resonance (13C NMR), Ultraviolet Visible (UV-Vis) and elemental analyzer (CHNS).
Fulltext Sedimentology, petrography, and reservoir quality of the Zarga and Ghazal formations in the Keyi oilfield, Muglad Basin, Sudan

Makeen YM, Shan X, Ayinla HA, Adepehin EJ, Ayuk NE, Yelwa NA, et al.

Sci Rep, 2021 01 12;11(1):743.

The Zarga and Ghazal formations constitute important reservoirs across the Muglad Basin, Sudan. Nevertheless, the sedimentology and diagenesis of these reservoir intervals have hitherto received insignificant research attention. Detailed understanding of sedimentary facies and diagenesis could enhance geological and geophysical data for better exploration and production and minimize risks. In this study, subsurface reservoir cores representing the Zarga formation (1114.70-1118.50 m and 1118.50-1125.30 m), and the Ghazal formation (91,403.30-1406.83 m) were subjected to sedimentological (lithofacies and grain size), petrographic/mineralogic (thin section, XRD, SEM), and petrophysical (porosity and permeability) analyses to describe their reservoir quality, provenance, and depositional environments. Eight (8) different lithofacies, texturally characterized as moderately to well-sorted, and medium to coarse-grained, sub-feldspathic to feldspathic arenite were distinguished in the cored intervals. Mono-crystalline quartz (19.3-26.2%) predominated over polycrystalline quartz (2.6-13.8%), feldspar (6.6-10.3%), and mica (1.4-7.6%) being the most prominent constituent of the reservoir rocks. Provenance plot indicated the sediments were from a transitional continental provenance setting. The overall vertical sequence, composition, and internal sedimentary structures of the lithofacies suggest a fluvial-to-deltaic depositional environment for the Ghazal formation, while the Zarga formation indicated a dominant deltaic setting. Kaolinite occurs mainly as authigenic mineral, while carbonates quantitatively fluctuate with an insignificant amount of quartz overgrowths in most of the analyzed cores. Integration of XRD, SEM, and thin section analysis highlights that kaolinite, chlorite, illite, and smectite are present as authigenic minerals. Pore-destroying diagenetic processes (e.g. precipitation, cementation, and compaction etc.) generally prevailed over pore-enhancing processes (e.g. dissolution). Point-counted datasets indicate a better reservoir quality for the Ghazal formation (ɸ = 27.7% to 30.7%; K = 9.65 mD to 1196.71 mD) than the Zarga formation (17.9% to 24.5%; K = 1051.09 mD to 1090.45 mD).

PMID: 24222756 DOI: 10.1155/2013/935981

Six parents of Jatropha curcas were crossed in half diallel fashion, and the F 1s were evaluated to determine the combining ability for nine germination parameters. The ratio between general combining ability (GCA) and specific combining ability (SCA) variances indicated preponderance of additive gene action for all the characters except germination percentage, time of 50% germination, seedling length, and seedling vigor index. The parents P 1 and P 2 were the best general combiner for most of the characters studied. The cross P 1 × P 5 was the best specific combiner for speed of emergence, germination percentage, germination energy, germination index, and seedling vigor index, the cross P 2 × P 5 for mean germination time, time of 50% germination, and seedling length, and the cross P 4 × P 5 for number of days to first germination. The germination percentage varied from 58.06 to 92.76% among the parents and 53.43 to 98.96% among the hybrids. The highest germination (98.96%) was observed in hybrid P 2 × P 4, and none of the hybrids or parents showed 100% germination. The highest germination index (GI) and seedling vigor index (SVI) were found in hybrid P 1 × P 5 and P 2 × P 5, respectively. The results of this study provide clue for the improvement of Jatropha variety through breeding program.

Public Underst Sci, 2011 Sep;20(5):674-89.
PMID: 22164706

Despite considerable research in advanced countries on public perceptions of and attitudes to modern biotechnology, limited effort has been geared towards developing a structural model of public attitudes to modern biotechnology. The purpose of this paper is to identify the relevant factors influencing public attitudes towards genetically modified (GM) soybean, and to analyze the relationship between all the attitudinal factors. A survey was carried out on 1,017 respondents from various stakeholder groups in the Klang Valley region. Results of the survey have confirmed that attitudes towards complex issues such as biotechnology should be seen as a multifaceted process. The most important factors predicting support for GM soybean are the specific application-linked perceptions about the benefits, acceptance of risk and moral concern while risk and familiarity are significant predictors of benefit and risk acceptance. Attitudes towards GM soybean are also predicted by several general classes of attitude.
Cutaneous larva migrans: a neglected disease and possible association with the use of long socks

Hamat RA, Rahman AA, Osman M, Unyah NZ, Abdullah WO, Isa NH

Trans R Soc Trop Med Hyg, 2010 Feb;104(2):170-2.
PMID: 19732927 DOI: 10.1016/j.trstmh.2009.07.019

Cutaneous larva migrans is a common parasitic skin disease that can be easily prevented by wearing 'protective' footwear. However, this has been under-emphasized in terms of what constitutes the protective footwear. Even though the disease resolves spontaneously, the significant duration of the disease along with severity of pruritus make treatment unavoidable. Here, we present a very long-standing creeping eruption, which puzzled many attending clinicians handling the case, and the possibility of long socks as a causal effect on the development of cutaneous larva migrans infection.
