Exploring Human Resource management practise through the Qatar HR Forum; framing the influence of 'Tharaba' culture and the development of Qatar-centric competencies for HR professionals practising in Qatar

Qatarisation policy has emerged from the Qatar National Vision 2030 and has become embedded into organisations’ core strategic visions. Qatarisation aims to place knowledgeable local Qataris into senior professional roles to lead their country. Human Development is a core pillar of the National Vision and is an expected responsibility of each organisation and its employees. This responsibility directly impacts the Human Resource Management (HRM) function and HRM professionals developing talent in Qatar. This is a challenge due to a lack of Qatar-centric frameworks available to HR Professionals practising in Qatar and a lack of understanding of influences on HRM Practises. The research focused on overcoming this challenge and contributing to a sustainable framework solution for HR professionals in Qatar. There were three main aims; to review HR literature while exploring the fundamental principles and context of the HR professional practise in Qatar; to explore ways HR practitioners in the Qatar HR Forum could drive and support a change in HRM practise, and to contribute to professionalising HRM Practise in Qatar. A qualitative interpretivistic approach explored the experiences and perceptions of HR professionals practising in Qatar, who are members of the Qatar HR Forum, through surveys, interviews, and focus groups, to understand the complexities of HRM in Qatar. The findings show that distinctive expatriate and Qatari influences need to be considered with a new framing of how Qatari culture might influence and impact current and future HRM practises. This has been conceptualised as ‘Tharaba Culture’ – ذرابه , which encompasses behaviours, customs, and unwritten expectations that locals acknowledge as their culture. It is based on influences such as family ties, leadership status, expected norms and non-negotiable behaviours, engulfed in the wisdom of the respected elders formulated from tribal descent. The research further impacts practise, with a significant outcome being the development of a Qatar-centric HR competency framework, which will provide a foundation for HR professionals to meet the unique challenges and complexities of HRM practise in Qatar

Numerical Studies for Solving Fractional Riccati Differential Equation

In this paper, finite difference method (FDM) and Pade\u27-variational iteration method (Pade\u27- VIM) are successfully implemented for solving the nonlinear fractional Riccati differential equation. The fractional derivative is described in the Caputo sense. The existence and the uniqueness of the proposed problem are given. The resulting nonlinear system of algebraic equations from FDM is solved by using Newton iteration method; moreover the condition of convergence is verified. The convergence\u27s domain of the solution is improved and enlarged by Pade\u27-VIM technique. The results obtained by using FDM is compared with Pade\u27-VIM. It should be noted that the Pade\u27-VIM is preferable because it always converges to the solution even for large domain

Pre-Participation Musculoskeletal and Cardiac Screening of Male Athletes in the United Arab Emirates

This study presents the results of pre-participation musculoskeletal and cardiac screening using the Lausanne recommendations, which include a personal and family history, physical examination and electrocardiography. Cross sectional study using the Lausanne screenings and the European Society of Cardiology (ESC) recommendations carried out at Al-Ahli club in Dubai, United Arab Emirates. 230 male athletes participating in organised sports were included. Exclusion criteria were those under 14 or over 35 years old, females and athletes with established cardiovascular disease. Primary outcome are the results of Lausanne screening with outline of the negative, positive and false positive results and number needed to screen. Secondary outcomes include the results of musculoskeletal and neurological screening. A total of 174 (76%) athletes had a negative screening result. Fifty-four athletes (23%) underwent additional testing. Forty-seven athletes (20.4%) had false positive screening results. Seven athletes (3%) had a positive screening result and four athletes (2%) were restricted from sport. The number of athletes needed to screen to detect one lethal cardiovascular condition was 33 athletes. The Lausanne recommendations are well suited for the United Arab Emirates. The number needed to screen to detect one athlete with serious cardiovascular disease is acceptable at 33

Investigation of the performance of a Solar Powered Adsorption Heat Pipe

An adsorption heat pipe was designed and built from a stainless steel tube of 32 mm outer diameter, 30 mm inner diameter and 1000 mm long, the inner surface of the tube was coated by 10 mm thickness of active carbon, which was assumed to be the adsorbent, while the adsorbent was assumed to be the methanol, or acetone. The adsorption heat pipe consist of three zones, namely adsorption/ desorption, adiabatic and evaporation/condensation zones. Electrical heater with variables capacity is used to heat up the unit generator during desorption process, water was used to cool the condenser, while air was used to cool the generator. Two types of adsorption pair are used, namely active carbon-methanol and active carbon-acetone. The effect of heat input to the generator on the heat pipe surface temperature and evaporator temperature are studied. The results showed that the adsorption heat pipe can work at a relatively low temperature namely 70-100 oC, the time required for cooling process in the range of 18 to 24 minutes, and activated carbon – Acetone pair gave a good behavior for the heat pipe due to the short cycle– time compared with that for activated carbon – Methano

Numerical Studies for Fractional-Order Logistic Differential Equation with Two Different Delays

A numerical method for solving the fractional-order logistic differential equation with two different delays (FOLE) is considered. The fractional derivative is described in the Caputo sense. The proposed method is based upon Chebyshev approximations. The properties of Chebyshev polynomials are utilized to reduce FOLE to a system of algebraic equations. Special attention is given to study the convergence and the error estimate of the presented method. Numerical illustrations are presented to demonstrate utility of the proposed method. Chaotic behavior is observed and the smallest fractional order for the chaotic behavior is obtained. Also, FOLE is studied using variational iteration method (VIM) and the fractional complex transform is introduced to convert fractional Logistic equation to its differential partner, so that its variational iteration algorithm can be simply constructed. Numerical experiment is presented to illustrate the validity and the great potential of both proposed techniques

Engineering of biomimetic mineralized layer formed on the surface of natural dental enamel

The problem of engineering a biomimetic mineralized layer on the surface of native dental tissue (bio-template) was considered in our work. The formation of the mineralized layer on a biotemplate is achieved with the use of nanocrystalline carbonate-substituted calcium hydroxyapatite (HAp), calcium alkali, and a complex of polyfunctional organic and polar amino acids. By applying the set of structural and spectroscopic methods of analysis we have confirmed the formation of a mineralized biomimetic HAp layer on the surface of bio-template with properties resembling those of natural hard tissue. The thickness of the biomimetic mineralized layer varies from 300 to 500 nm, while the direction of some ncHAp nanocrystals coincides with that of the apatite crystals in the enamel. We also demonstrated that the engineered mineralized HAp layer was characterized by homogeneous micromorphology and enhanced nanohardness in the region of the enamel rods exceeding those of native enamel. The development of a strategy for biomimetic engineering and a technique for enamel surface pre-treatment to enable tissue mineralization has huge potential in dental applications. © 2022 The AuthorsRussian Science Foundation, RSF: 21-75-10005; Ministry of Science and Higher Education of the Russian Federation: N 075-15-2021-1351This work was funded by the Russian Science Foundation , grant number 21-75-10005 ;The access to scientific equipment and methodology was provided under support of the Ministry of Science and Higher Education of Russia, Agreement N 075-15-2021-1351

Genome-Wide Association Study for Identification and Validation of Novel SNP Markers for \u3ci\u3eSr6\u3c/i\u3e Stem Rust Resistance Gene in Bread Wheat

Stem rust (caused by Puccinia graminis f. sp. tritici Erikss. & E. Henn.), is a major disease in wheat (Triticum aestivium L.). However, in recent years it occurs rarely in Nebraska due to weather and the effective selection and gene pyramiding of resistance genes. To understand the genetic basis of stem rust resistance in Nebraska winter wheat, we applied genome-wide association study (GWAS) on a set of 270 winter wheat genotypes (A-set). Genotyping was carried out using genotyping-by-sequencing and ~35,000 high-quality SNPs were identified. The tested genotypes were evaluated for their resistance to the common stem rust race in Nebraska (QFCSC) in two replications. Marker-trait association identified 32 SNP markers, which were significantly (Bonferroni corrected P \u3c 0.05) associated with the resistance on chromosome 2D. The chromosomal location of the significant SNPs (chromosome 2D) matched the location of Sr6 gene which was expected in these genotypes based on pedigree information. A highly significant linkage disequilibrium (LD, r2) was found between the significant SNPs and the specific SSR marker for the Sr6 gene (Xcfd43). This suggests the significant SNP markers are tagging Sr6 gene. Out of the 32 significant SNPs, eight SNPs were in six genes that are annotated as being linked to disease resistance in the IWGSC RefSeq v1.0. The 32 significant SNP markers were located in nine haplotype blocks. All the 32 significant SNPs were validated in a set of 60 different genotypes (V-set) using single marker analysis. SNP markers identified in this study can be used in marker-assisted selection, genomic selection, and to develop KASP (Kompetitive Allele Specific PCR) marker for the Sr6 gene

Factors Associated with High Prevalence of Intestinal Protozoan Infections among Patients in Sana'a City, Yemen

Intestinal protozoan diseases in Yemen are a significant health problem with prevalence ranging from 18% to 27%. The present study is a cross-sectional study aimed at determining the factors associated with the high prevalence of intestinal protozoan infections among patients seeking health care in Sana'a City, the capital of Yemen. (0.4%). Multivariate analysis using forward stepwise logistic regression based on intestinal protozoan infections showed that contact with animals (OR = 1.748, 95% CI = 1.168–2.617) and taking bath less than twice a week (OR = 1.820, 95% CI = 1.192–2.779) were significant risk factors of protozoan infections. infections being most common. Statistical analysis indicated that low personal hygiene and contact with animals were important predictors for intestinal protozoan infections. As highlighted in this study, in order to effectively reduce these infections, a multi-sectoral effort is needed. Preventive measures should include good hygienic practices, good animal husbandry practices, heightened provision of educational health programs, health services in all governorates including rural areas. Furthermore, it is also essential to find radical solutions to the recent water crises in Yemen
