Afterward, 18S rDNA was amplified using specific primers to identify the nematode. <strong>Results: </strong>The Nblast analysis based on the small subunit ribosomal DNA showed 99% similarity with a population of <em>Xiphinema index </em>(JQ026520) from Iran (Kerman Province). In addition, phylogenetic analysis using the neighbor-joining method as implemented in mega x software was done. The phylogenetic analysis put the Iranian populations of <em>X. index </em>together with another <em>X. index </em>with a 100-bootstrap value. <strong>Conclusion: </strong>Despite 18S rDNA are a helpful marker for <em>X. index</em> identification, however, this species' diversity needs to be investigated to determine the impact of this nematode on the yield loss of the crops associated with it.</p> Mehrnoush Aminisarteshnizi Copyright (c) 2022 Transylvanian Review http://creativecommons.org/licenses/by-nc-nd/4.0 http://transylvanianreviewjournal.com/index.php/TR/article/view/927 Wed, 28 Sep 2022 19:56:13 +0300 Computational analysis for optimum multiphase flowing bottom-hole pressure prediction http://transylvanianreviewjournal.com/index.php/TR/article/view/907 <p>Computer intelligent models are the order of the day for the manipulation of data to better understand the trend of complex situations under the questioned industry. The petroleum engineering is faced with multiple datasets from production logging tools and predictive analysis without these computer intelligent tools can be devastating. Errors of margins under these circumstances cannot be easily prevented, which may lead to some biases in the decision-making processes, thereby affecting the cost of operations and services in the industry.<strong> </strong>This study used an open-source dataset from a production well logging tool to evaluate and affirm the accuracy of a computer intelligent model, suitable for processing complex problems. However, an artificial neural network under the feedforward function and a model fitting-multilinear regression were used for this predictive analysis. Conclusively, the predictive analysis, whiles considering the coefficient of determination for these two models resulted that, the artificial neural network- feedforward function was better in predicting the flowing bottom-hole pressures than the multilinear regression. Multiphase flow under bottom-hole pressures can further be computed using CFD to determine variations of pressure drops, predicting flow patterns and geometry to enhance prudent decision-making analysis.<strong></strong></p> Ugochukwu I.

Technical efficiency and its components are measured with The Data envelopment analysis (DEA) based CCR and BCC models. The Lerner index is used to measure competition among the Pakistani banks. For econometric estimation, the bootstrap truncated regression is used. The results of the study showed that the competition, risk, size, taxation, diversification, operational cost management, banking development, trade openness and infrastructure development significantly affected the Technical efficiency. The comparative study indicates that the state-owned banks have higher technical efficiency than the private, foreign and Islamic banks.

The aim of this study was to explore the challenges faced regarding the separation at source (S@S) programme by a major municipality in South Africa.</p><p><strong>Materials and Methods</strong></p><p>A qualitative study was conducted among a purposeful sample of 15 employees of a Separation at Source (S@S) recycling project in the City of Johannesburg (CoJ), South Africa. <strong></strong></p><p><strong>Findings </strong></p><p>Four major themes and several sub-themes emerged for an analysis of the data, namely, recycling regulations, recycling participation rates, recycling behaviours and recycling challenges. Recycling behaviour emerged as the most important theme in this study and attitudes to recycling was the most important sub-theme.</p><p><strong>Conclusion</strong></p>These findings will benefit the CoJ since it provides insights into the challenges faced when implementing waste management programmes. It is recommended that the CoJ provide structure and support to employees responsible for the implementation of recycling programmes to ensure optimal outcomes. It should also increase efforts at creating greater awareness of the importance of recycling and invest in educational campaigns targeted at teaching residents the importance of recycling and how to recycle effectively. Moreover, the CoJ should create strategies to ensure that recycling is convenient for residents and the effort and time taken to recycle must be minimized. Most importantly, the CoJ should increase recycling rates by encouraging organizations and institutions to implement S@S in the workplace. Krishna K.

Free-living can be classified as bacterivores, fungivores, omnivores, and predators and thus contribute to fundamental ecological processes in the soil, such as decomposition and nutrient cycling. <strong>Materials and Methods: </strong>Seven nematode species were identified from the soil samples during a survey on free-living nematodes in five almond (<em>Prunus dolcis Mill</em>.) orchards. The samples were collected across the orchards in the central part of Iran. <strong>Results: </strong>Out of the 15 soil samples collected in 2017, the most prevalent nematodes encountered were <em>Cephalobus persegnis</em> (2345), <em>Butlerius butleri </em>(560), and <em>Panagrolaimus rigidus </em>(230). The CCA results indicated that<em> C. persegnis, B. butleri, </em>and<em> Mesorhabditisi </em>sp. were more affected on K%, Ca%, Carbon%, Silt%, and Clay% found in Kharaji Teshneez orchards. However, <em>P. rigidus</em>, <em>Aporcelaimellus </em>sp<em>., Prismatolaimus </em>sp., and <em>Geomonhystera </em>sp. were dominant in substrates characterized by Na%, pH (KCl), Mg%, and Sand% in Saman, Chelvan, and ChamAli orchards. <strong>Conclusion: </strong>The diversity of free-living nematodes in Saman, ChamAli, and Chelvan was higher than in other orchard localities. Many free-living nematodes on the rhizosphere of almond tress may be due to the regular application of organic manure.</p> Mehrnoush Aminisarteshnizi Copyright (c) 2022 Transylvanian Review http://creativecommons.org/licenses/by-nc-nd/4.0 http://transylvanianreviewjournal.com/index.php/TR/article/view/926 Wed, 28 Sep 2022 19:49:22 +0300 Closed-Form Solution of European Option under Fractional Vasicek Model http://transylvanianreviewjournal.com/index.php/TR/article/view/916 <span>This paper specifically deals with how the powerful tools of fractional calculus are applied to compute European option prices under the Fractional Vasicek Model.</span> Seham Al.

Low back pain is one the most common musculoskeletal problem experienced among nurses.</p><p> <strong>Aim</strong>: The aim of this study was to explore the prevalence of low back pain among nurses in Jordan and to determine the associated risk factors and consequences.</p><p><strong> Methods</strong>: A cross-sectional study was conducted involving 526 nurses working in various government and non-government healthcare settings in Jordan. A modified version of The Nordic Musculoskeletal Disorder Questionnaire was used to obtain the information about demographic data, work related activities and details on low back pain.</p><p> <strong>Results</strong>: A total of 374 (71.1%) of the nurses experienced low back pain of which 58.6% classified their pain as acute, and 68% of the nurses evaluated their pain as "moderate and severe". It was determined that 56.6% of nurses working in in-patient departments had higher average of pain scores. The results also revealed that the factors significantly associated with low back pain among nurses included: Age, experience, working setting, duration of low back pain, nature of job, and number of working hours.</p><strong>Conclusion</strong>: The high prevalence of low back pain requires the need for nurses and managers to enhance risk awareness, improve physical and psychosocial working conditions, and promote a safer work environment.

The development of communication skills is fundamental in health professionals and one of the recommended techniques to organize this process is SBAR (Situation-Background-Assessment-Recommendation). However, no validated instruments are known to assess the achievement of communication competencies. Materials and methods: The methodology considered four stages. Literature review, the basic criteria of the instrument were established according to 65% agreement of the reviewed authors. Judgment by internal experts, who review the initial instrument and make observations. Judgment by external experts, who review the completed items and make suggestions. And pilot, where the instrument is tested on thirty-seven students. Results: Ten criteria were eliminated in the first and second stages. After the validation of external experts, the wording of some criteria was modified according to observations of content, clarity and relevance, obtaining the instrument for piloting. The statistical analysis of the pilot was done in Excel, the answers of the 37 students in the 35 total criteria of the instrument, obtaining that the instrument has a high internal consistency, obtaining a Cronbach's alpha of 0.83. Conclusion: A validated instrument will standardize the evaluation of the delivery of information with SBAR in nursing students, allowing conclusions to be drawn and facilitating decision-making in relation to the training requirement of these poorly studied communication skills in CS.

This study investigated laboratory findings and the effect of different drugs on the survival of COVID-19 patients.</p> <p><strong>Methods</strong></p> <p>This was a retrospective single center study of 203 COVID19 inpatients. Patients included in this study were adults with moderate to severe COVID-19 symptoms including respiratory manifestations.</p> <p><strong>Results</strong></p> <p>Among 203 patients 88(43.3%) died while 115 (56.7%) survived. Among 65 patients on Favipiravir, 39 of patients died. Mortality in patients taking Azithromycin, Meropenem, Ceftriaxone and Linezolid were 28%, 64.2%, 23.9% and 65% respectively. Imipenem-Cilastatin Sodium was administered by 14 patients, only 4 of those were recovered. Fifty-seven patients on azithromycin survived and 16 died, while 88% out of the 25 patients taking Moxifloxacin survived. Survival in the 48 patients taking vancomycin was 20.8%. There was a significant difference between survival and death in all laboratory parameters. Statistical analysis also showed independent predictors of mortality per drug. Higher survival rates were also noted in patients on Dexamethasone, but not in hydrocortisone or prednisolone. The use of Enoxaparin, rather than clopidogrel, aspirin or heparin was also shown to be related to lower mortality.</p> <p><strong>Conclusion</strong></p> <p>The data gives an overview about the pharmacological management of hospitalized COVID-19 patients. The study findings might help to identify the drugs with positive outcome and lower mortality.</p> Amer Ayed Alahmadi, Najwa Mahmoud Almaghrabi, Waleed Talal Obaid, Maisaa Muhammad A.

A link was posted on the researcher’s social media pages and emailed to peers at work and the university where the researcher was a student. The survey included questions which required respondents to rank on a scale of 1-5, statements related to each CSR category.</p> <p>Results</p> <p>It became evident that contrary to Carroll’s CSR framework/pyramid, South African consumers perceive CSR in the following order: Legal, Economic, Philanthropic and Ethical, which could be influenced by inter-alia, South African legislation such as Black Economic Empowerment, the King Code of Corporate Governance and because South African consumers perceive philanthropic responsibilities to be more important than ethical ones. The only CSR category which had a partial influence on consumer support, was philanthropic responsibilities, which is in line with the notion that philanthropy is more highly valued in developing countries.</p> <p>Conclusion</p> <p>South African banks can use the findings from this study to better allocate their CSR resources.</p> N.
