Power-law entropy-corrected HDE and NADE in Brans-Dicke cosmology

Considering the power-law corrections to the black hole entropy, which appear in dealing with the entanglement of quantum fields inside and outside the horizon, the holographic energy density is modified accordingly. In this paper we study the power-law entropy-corrected holographic dark energy in the framework of Brans-Dicke theory. We investigate the cosmological implications of this model in detail. We also perform the study for the new agegraphic dark energy model and calculate some relevant cosmological parameters and their evolution. {As a result we find that this model can provide the present cosmic acceleration and even the equation of state parameter of this model can cross the phantom line $w_D=-1$ provided the model parameters are chosen suitably}.Comment: 14 pages, 2 figure, accepted by IJT

Children of Iraqi Refugees: Risk Profile for Substance Abuse

What is the risk profile of children of Iraqi refugees? Among adult refugees, higher prevalence of mental disorders has been associated with shorter time since resettlement and exposure to more potential traumatic events (PTE). We hypothesized that similar associations would hold in the children of Iraqi refugees

The Variations in the Altitudes Between the Sea Level and Ajloun Impact Heart Variables, but not Angiotensin Ii

Background: hypertension affects many people worldwide and it is highly prevalent in Jordan. Living at different areas with different attitudes may have impacts in hypertension. Study objectives: to identify the prevalence of hypertension in two areas in Jordan with different attitudes and to determine the impact of attitudes in hypertension and angiotensin II to be able to determine the appropriate antihypertensive drug for such population. Methodology: a cross-sectional study design was conducted to collect data from participants. The study included 1000 participants, 500 from each area. A constructed questionnaire was used in this study. Blood samples were taken from participants to assay for angiotensin II. Blood pressure was measured for all patients. Data was analyzed using SPSS version 20. Data was presented as means, frequencies, percentages. The relationship between variables was examined using independent T-test. Significance was considered at alpha level 0.05). Conclusions: living in high altitude is associated with increased potential to have increased levels of cardiac parameters independently of the level of angiotensin II and the therapeutic options for patients with hypertension should be taken into account

System-level determinants of immunization coverage disparities among health districts in Burkina Faso: a multiple case study

<p>Abstract</p> <p>Background</p> <p>Despite rapid and tangible progress in vaccine coverage and in premature mortality rates registered in sub-Saharan Africa, inequities to access remain firmly entrenched, large pockets of low vaccination coverage persist, and coverage often varies considerably across regions, districts, and health facilities' areas of responsibility. This paper focuses on system-related factors that can explain disparities in immunization coverage among districts in Burkina Faso.</p> <p>Methods</p> <p>A multiple-case study was conducted of six districts representative of different immunization trends and overall performance. A participative process that involved local experts and key actors led to a focus on key factors that could possibly determine the efficiency and efficacy of district vaccination services: occurrence of disease outbreaks and immunization days, overall district management performance, resources available for vaccination services, and institutional elements. The methodology, geared toward reconstructing the evolution of vaccine services performance from 2000 to 2006, is based on data from documents and from individual and group interviews in each of the six health districts. The process of interpreting results brought together the field personnel and the research team.</p> <p>Results</p> <p>The districts that perform best are those that assemble a set of favourable conditions. However, the leadership of the district medical officer (DMO) appears to be the main conduit and the rallying point for these conditions. Typically, strong leadership that is recognized by the field teams ensures smooth operation of the vaccination services, promotes the emergence of new initiatives and offers some protection against risks related to outbreaks of epidemics or supplementary activities that can hinder routine functioning. The same is true for the ability of nurse managers and their teams to cope with new situations (epidemics, shortages of certain stocks).</p> <p>Conclusion</p> <p>The discourse on factors that determine the performance or breakdown of local health care systems in lower and middle income countries remains largely concentrated on technocratic and financial considerations, targeting institutional reforms, availability of resources, or accessibility of health services. The leadership role of those responsible for the district, and more broadly, of those we label "the human factor", in the performance of local health care systems is mentioned only marginally. This study shows that strong and committed leadership promotes an effective mobilization of teams and creates the conditions for good performance in districts, even when they have only limited access to supports provided by external partners.</p> <p>Abstract in French</p> <p>See the full article online for a translation of this abstract in French.</p

A Methodological Approach to Assessing the Tribological Properties of Lubricants Using a Four-Ball Tribometer

Based on the analysis of standards for the testing of lubricants, both liquid and plastic, on a four-ball tribometer, and the analysis of the parameters by which lubricants are evaluated, this paper proposes a methodology and an integral parameter for the estimation of tribological properties. The methodological approach proposed in this paper allows for the integration of a variety of parameters provided in the standards for the testing of lubricants into one indicator. Herein, we show that the developed technique is based on the energy approach and takes into account the specific wear work of the test material (steel balls) in the lubricating medium to be investigated. The results of laboratory tests of a wide range of lubricants are presented: hydraulic fluids, motor and transmission oils of various purposes and classifications. It is shown that the magnitude of the integral parameter can be used to assess the effectiveness of anti-wear and anti-scuff additives in base lubricants, as well as the ranges of their applications. This allows for differentiation and quantitative evaluation of the effectiveness of such additives. The obtained results allow us to state that all tests according to the developed method are reproducible and homogeneous, which is confirmed using the Cochran criterion. The coefficient of variation during testing does not exceed 18%. We show that the presented methodology and the integral parameter can be used in the first stage of the laboratory selection tests of new lubricants and additives of various origins, reducing the costs of their development and implementation

Indications for Surgery, Activities After Surgery, and Pain Are the Most Commonly Asked Questions in Anterior Cruciate Ligament Injury and Reconstruction

PURPOSE: To leverage Google\u27s search algorithms to summarize the most commonly asked questions regarding anterior cruciate ligament (ACL) injuries and surgery. METHODS: Six terms related to ACL tear and/or surgery were searched on a clean-installed Google Chrome browser. The list of questions and their associated websites on the Google search page were extracted after multiple search iterations performed in January of 2022. Questions and websites were categorized according to Rothwell\u27s criteria. The Journal of the American Medical Association (JAMA) Benchmark criteria were used to grade website quality and transparency. Descriptive statistics were provided. χ(2) and Student t-tests identified for categorical differences and differences in JAMA score, respectively (significance set at P \u3c .05). RESULTS: A total of 273 unique questions associated with 204 websites were identified. The most frequently asked questions involved Indications/Management (20.2%), Specific Activities (15.8%), and Pain (10.3%). The most common websites were Medical Practice (27.9%), Academic (23.5%), and Commercial (19.5%). In Academic websites, questions regarding Specific Activities were seldom included (4.7%) whereas questions regarding Pain were frequently addressed (39.3%, P = .027). Although average JAMA score was relatively high for Academic websites, the average combined score for medical and governmental websites was lower (P \u3c .001) than nonmedical websites. CONCLUSIONS: The most searched questions on Google regarding ACL tears or surgery related to indications for surgery, pain, and activities postoperatively. Health information resources stemmed from Medical Practice (27.9%) followed by Academic (23.5%) and Commercial (19.5%) websites. Medical websites had lower JAMA quality scores compared with nonmedical websites. CLINICAL RELEVANCE: These findings presented may assist physicians in addressing the most frequently searched questions while also guiding their patients to greater-quality resources regarding ACL injuries and surgery
