RENEWAL REWARD PROCESSES

Abstract : The paper considers a process in which rewards are being earned and for which there exist time points at which the process begins anew--that is, that there exists an embedded renewal process. An expression for the asymptotic mean reward earned during any time interval is then obtained. In the final section the special case of a regenerative reward process is considered and a simple expression is presented for the long run average reward earned per unit time.
External Environmental Factors and Organizational Productivity in Selected Oil Service Firms in Port Harcourt

External environment is a firm’s aggregate of factors, exogenous to the organization that may have potential to affect organizational performance. The main objective of the study was to examine the effect of external environmental factors on organizational productivity in oil service firms in Port Harcourt, River State. Resource dependency theory was employed as the theoretical framework for the study. The study adopted survey research design. The population of the work constituted 1875 employees from 20 randomly selected oil service firms. The sample size for the study was 330 arrived at using Taro Yamane formula. The data generated through questionnaire were analyzed using multiple regression analysis. The findings revealed that technological factors have significant effect on organizational productivity and that political factors have significant effect on organizational productivity. The study further indicated that economic factors have significant effect on organizational productivity and that socio-cultural factors have significant effect on organizational productivity. It was therefore concluded that external environmental factors have significant effect on organizational productivity in oil servicing firms in Port Harcourt. The study recommended among other things that oil service firms should be proactive in dealing with the changes and trends in external environmental environment. The found on organizational The study also on organizational productivity. The study found that economic factors have significant effect on organizational productivity. The study further revealed socio-cultural effect on organizational productivity. Based on the foregoing, the study concludes that external environmental factors have on organizational in
agronomy Exercise, Urban Food Production, Preparation and Consumption: Implications, Beneﬁts and Risks to Grow-Your-Own (GYO) Gardeners

: This study is the ﬁrst to consider, and estimate, the inﬂuence of gardening routines on exposures to both health beneﬁts and health risks. This holistic approach helped to contrast the healthy lifestyle of gardening with health risks from exposures to potentially toxic elements such as Cd and Pb in urban environments. A total of 120 participants who grew their own produce in an urban setting were recruited to the study. A detailed questionnaire was developed that included sections on gardening activity, cultivation and consumption of produce, consumption of commercially grown produce, and other lifestyle factors. Administered alongside the questionnaire was the Short Form 36 (v2) as a standardised tool for measuring physical and mental health. Fruit and vegetable consumption was found to be correlated with the amount of gardening individuals did in autumn/winter and was greater than fruit and vegetable consumption, on average, in the UK general population. Levels of physical activity were also found to be higher in our study than regional averages, whilst BMI was lower than average. This is the ﬁrst study to ﬁnd a relationship between gardening more regularly (in autumn/winter) and the physical component of the Short Form 36, and this relationship was elevated compared to non-gardening populations. The physical component scores from this study were also signiﬁcantly higher for older participants, compared to means from a Western population. This ﬁnding supports studies suggesting that gardening may be more beneﬁcial for the elderly generation. These beneﬁts were assessed in the context of potential exposures estimated from the type and frequency of produce being consumed. The beneﬁt of maintaining a healthy lifestyle is likely to outweigh the health risks of gardening on soils mildly contaminated with Cd and Pb but requires formal consideration within a risk management framework.

TCRM_A_234772 715..726

Joseph J Cuthbert 1 Pierpaolo Pellicori 2 Andrew L Clark 1Department of Academic Cardiology, Hull York Medical School, Hull and East Yorkshire Medical Research and Teaching Centre, Castle Hill Hospital, Kingston upon Hull HU16 5JQ, UK; 2Robertson Institute of Biostatistics and Clinical Trials Unit, University of Glasgow, University Avenue, Glasgow G12 8QQ, UK Abstract: One of the defining features of heart failure (HF) is neurohormonal activation. The renin-angiotensin-aldosterone-system (RAAS) and sympathetic nervous system (SNS) cause vasoconstriction and fluid retention and, in response, the secretion of natriuretic peptides (NPs) from volume and pressure-overloaded myocardium promotes vasodilation and diuresis. Inhibition of the RAAS with either angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) has been the cornerstone of medical treatment for HF with a reduced ejection fraction (HFrEF) but, until recently, it was unclear how the beneficial effects of NPs may be augmented in patients with HF. Neprilysin, a metalloproteinase widely distributed throughout the body, plays a role in degrading the gross excess of circulating NPs in patients with HF. Early studies of neprilysin inhibition suggested possible physiological benefits. In 2014, the PARADIGM-HF trial found that sacubitril-valsartan, a combination of the ARB valsartan, and the neprilysin inhibitor sacubitril, was superior to enalapril in patients with HFrEF, reducing the relative risk of cardiovascular (CV) death or first hospitalisation with HF by 20%. Almost half of the patients with HF symptoms have a “preserved” ejection fraction (HFpEF); however, the PARAGON-HF study found that sacubitril-valsartan in patients with LVEF ≥45% had no effect on CV death or first and recurrent hospitalisations with HF compared to valsartan. Guidelines across the world have changed to include sacubitril-valsartan for patients with HFrEF yet, nearly 6 years after PARADIGM-HF, there is still uncertainty as to when and in whom sacubitril-valsartan should be started. Furthermore, there may yet be subsets of patients with HFpEF who might benefit from treatment with sacubitril-valsartan. This review will describe the mechanisms behind the outcome benefit of sacubitril-valsartan in patients with HFrEF and to consider its future role in the management of patients with HF.
Role of vitamin D, interleukin-17A and interleukin-10 levels in women with recurrent miscarriage

Background: RPL is a common early pregnancy complication that is characterized as three or more pregnancy losses occurring before the 20th week of gestation. RPL is a common early pregnancy complication that is characterized as three or more pregnancy losses occurring before the 20th week of gestation. Recurrent miscarriage (RM) is a common occurrence, affecting 15–25% of all pregnancies. The study's goal was to assess vitamin D, interleukin-17a, and interleukin-10 levels in women who had several miscarriages and investigate the relationship between biomarkers to determine the final outcome of pregnancy. Methods: A case control study that included three study groups; thirty five women with RPL, thirty non-aborted pregnant (NAP) women and twenty five apparently healthy women. Patients were selected from those attending Bint Al-Huda Teaching Hospital and Suq Al-Shuyukh General Hospital at Thi-Qar Province (Iraq) during the period between October 2021 and July 2022 after stringent application of the eligibility criteria. Serum samples was collected form each subjects and was evaluated for serum VD, IL-17A and IL-10 levels via enzyme-linked immunosorbent assay (ELISA). Results: The results revealed that serum VD and IL-10 levels in the RPL group were significantly lower than in the healthy control group (HC).
Scientific Initiation as a strategy for the development of Scientific Literacy in basic education students: reflections from the Cientista Aprendiz

Scientific initiation has benefits for scientific education, but few studies focus on schools. Thus, we investigated a Program of Scientific Initiation offered by a private school in São Paulo. We aimed to identify: i) a number of students that were participated in this program (2006 to 2019); ii) the areas and themes that were researched by the participants; iii) possible gender differences. We analyzed some documents, did some statistical tests, and did an Open Data Categorization. We identified the growth of student enrollments, indicating an enlargement of their interest in scientific topics. We also identified a greater number of researches in Biological Sciences, but gender differences were not identified, just an asymmetry in the areas of interest of students. More spaces for the development of the Nature of Science in schools are necessary, as well as the constant dialogue about the insertion of women in scientific careers.
In vitro, evaluation of some medicinal plants extracts against Fusarium oxysporum f. sp. lycopersici

This work evaluates the efficacy of aqueous and ethanolic extracts of fourteen medicinal plants as antifungal agents against Fusarium oxysporum f. sp. lycopersici . Extracts were used at five concentrations (0.0, 0.5, 1.5, 2.5, 5% w/v). Allium sativum was the most efficient when used in both aqueous and ethanolic extracts, followed by Datura stramonium whereas the least effective species were Lantana camara and Ficus elastica . In general, the ethanolic extract exhibited a more potent inhibitory effect on the growth of F. oxysporum f. sp. lycopersici than the aqueous extract, and this was particulary evident for Citrus reticulata, Eucalyptus rostrata , Mentha piperita, Cupressus macrocarpa and Eugenia jambolana . However, Allium sativum and Datura stramonium were the most potent species in addition to Malva parviflora , Althaea rosea, Nigella sativa and Artemisia herba-alba . The dose-response relationship differed according to plant species and the extract used.
Instability of a moving contact line

We study a solid plate plunging into or being withdrawn from a liquid bath, to highlight the fundamental difference between the local behavior of an advancing or a receding contact line, respectively. It is assumed that the liquid partially wets the solid, making a finite contact angle in equilibrium. In our hydrodynamic description which neglects the presence of the outer gas atmosphere, an advancing dynamic wetting line persists to arbitrarily high speeds. The receding wetting line, on the other hand, vanishes at a critical speed set by the competition between viscous and surface tension forces. In the advancing case, we apply existing matching techniques to the plunging plate geometry, to significantly improve on existing theories. For the receding contact line, we demonstrate for the first time how the local contact line solution can be matched to the far-field meniscus. In doing so, we confirm our very recent criterion for the instability of the receding contact line. The results of both the advancing and the receding cases are tested against simulations of the full model equations.
The Characteristics of Coconut Oil Products Based on Papaya Juice and Duration Fermentation using Rhizopus sp.

Coconut oil is a basic human need. Coconut oil can be made both traditional and enzymatically. Enzymatic manufacture of coconut oil is the separation of oil in coconut milk using protein-breaking enzymes called proteolytic enzymes. Enzymatic production of coconut oil has the advantages of easy-to-obtain raw materials, does not require much energy, and simple processing. This study was conducted to determine the effect of time and amount of papaya juice used with the coconut oil yields obtained. The results of the study at a time of 3 days with a volume of 75 ml of papaya juice, it was obtained that the volume of coconut oil was the most, which was 11.4 ml. Making coconut oil using coconut milk and papaya juice mixed and added 2 grams of tempeh yeast then measured the pH to pH 4. Next, the glass is closed so that air does not enter during the fermentation time of 3-5 days. After being fermented then separated between water and pulp from making coconut oil. Next, pulp from making coconut oil is heated to produce oil. In addition, the free fatty acid test and the saponification number test were also carried out to determine whether the coconut oil produced complies with the quality requirements of SNI 2902-2011. This indicates that some treatment effect of coconut oil compiles is possible, a quality requirement of SNI 2902-2011.
Large N gauge theories and AdS/CFT correspondence

In the first part of these lectures we will review the main aspects of large N QCD and the explicit results obtained from it. Then, after a review of the properties of N=4 super Yang-Mills, type IIB string theory and of AdS space, we briefly discuss the Maldacena conjecture. Finally in the last part of these lectures we will discuss the finite temperature case and we show how "hadronic" quantities as the string tension, the mass gap and the topological susceptibility can be computed in this approach.
Tripling the capacity of a point‐to‐point radio link by using electromagnetic vortices

In this paper we report the results from outdoor experiments showing that it is possible to increase the data transmission capacity using at least three coherent, orthogonal beams on the same frequency, 17.128 GHz, each in a unique orbital angular momentum state. Each beam was encoded with the digital modulations used in present‐day telecommunications. We achieved an error‐free throughput of 3 × 11 Mbit/s with four‐Quadrature Amplitude Modulation over a 7 MHz bandwidth over 100 m and 150 m long links.
The association between school-aged children’s self-reported levels of playfulness and quality of life: a pilot investigation

ABSTRACT Playfulness and quality of life (QoL) appear to be related constructs; however, no studies have explored the potential association between them to date. Playfulness and QoL are important practice-related concepts for education and therapy professionals who work with children and their families. This study examined the potential links between children's self-reported playfulness and QoL. Thirty-one typically developing children aged 8–12 years (average age 10 years and 9 months, standard deviation = 1.12; 61.29% female) completed the Children's Perceptions of Their Play and the KIDSCREEN-52 instruments. It is noted that the onset of the COVID-19 pandemic during 2020 made participant recruitment and the execution of the study challenging. Data were analyzed using Spearman rho correlations and linear regression with bootstrapping. Data analysis results revealed statistically significant associations and predictive relationships between QoL-related physical wellbeing to active play and free time; QoL-related psychological wellbeing to the child's overall playfulness; the child's reported levels of QoL-related autonomy and their free time; and the child's QoL-related school environment to planned activities (p < .05 & p < .01). The study findings provide preliminary evidence that significant correlation and predictive relationships exist between aspects of children's self-reported playfulness and quality of life.
Validity and Practicality of Chemical Equilibrium Electronic Student Worksheets Based on Guided Discovery Learning to Increase the Critical Thinking Ability

Chemical equilibrium is an abstract chemical material that includes concepts and calculations. The purpose of this study was to develop and produce chemical equilibrium electronic student worksheets based on guided discovery learning to improve students’ critical thinking skills and fulfill the criteria for validity and practicality. This research and development use the Plomp model which consist of three stages, namely the preliminary research phase, prototyping phase, and the assessment phase. The validity and practicality of the teaching materials developed were obtained through research instruments in the form of validation and practicality questionnaires. Validation was carried out by 6 material expert validators and three media expert validators while practicality was carried out by 40 students of 11thgrade high school students and three chemistry teachers. The data analysis technique used is Aiken’s V technique for validity and the percentage technique for practicality. The results of the analysis of the material expert validation and media expert validation data based on the average Aiken’s V value showed a result of 0.84 and 0.89 with a very valid category. The results of the practicality of the electronic student worksheets were 84.87 and 92.11 with a very high category
Michigan Marijuana Legalization: Correlations Among Cannabis Use, Mental Health, and Other Factors

Introduction: There are health implications with the statewide legalization of recreational marijuana that are still not fully understood and require further examination. This study evaluates the prevalence of marijuana use in patients being treated for a variety of conditions and whether correlations exist between marijuana use, mental health conditions, and concomitant use of psychotropic medications. Methods: Data were collected from an electronic medical record (EMR) as part of a retrospective chart audit. A total of 500 charts were reviewed during a six-month timeframe from December 1, 2018 to May 31, 2019 with the start date approximating the timing of when marijuana became recreationally legalized in the State of Michigan. Results: This study demonstrated a point prevalence of 15.8% since 79 of the 500 charts reviewed had marijuana use documented. Additionally, marijuana users were more likely to have a history of cocaine use, schizophrenia, antipsychotic use, and tobacco use. Conclusion: Trends identified in this study provide a comparison point for the local prevalence of marijuana use immediately post state-wide legalization, with a projected increasing trend due to the removal of legal barriers.
Remarks on definition of Khovanov homology

Mikhail Khovanov in math.QA/9908171 defined, for a diagram of an oriented classical link, a collection of groups numerated by pairs of integers. These groups were constructed as homology groups of certain chain complexes. The Euler characteristics of these complexes are coefficients of the Jones polynomial of the link. The goal of this note is to rewrite this construction in terms more friendly to topologists. A version of Khovanov homology for framed links is introduced. For framed links whose Kauffman brackets are involved in a skein relation, these homology groups are related by an exact sequence.
Moishezon twistor spaces on 4CP^2

In this paper we classify all Moishezon twistor spaces on 4CP^2. The classification is given in terms of the structure of the anticanonical system of the twistor spaces. We show that the anticanonical map satisfies one of the following three properties: (a) birational over the image, (b) two to one over the image, or (c) the image is two-dimensional. We determine structure of the images for each case in explicit forms. Then we intensively investigate structure of the twistor spaces in the case (b), and determine the defining equation of the branch divisor of the anticanonical map.
Life-Purpose Orientations and Academic Misconduct Among University Students in Mexico

Academic misconduct has been conceptualized as students’ engagement in various types of proscribed behaviors, such as plagiarism and cheating on assignments and tests or exams (e.g., Stephens et al., 2021). While most of the current literature on academic misconduct has focused on developed countries, the problem is rampant across the world (Krou et al., 2021), especially in developing countries (e.g., Gaytán & Quintanilla-Domínguez, 2014; Stephens et al., 2010). Gaytán and QuintanillaDomínguez (2014), for example, found that the rate of academic misconduct in Mexican universities was significantly higher than the estimated rate in the United States. More recently, GuerreroDib et al. (2020) found that students who reported engaging in academic misconduct were more likely to be dishonest in nonacademic contexts. Surprisingly, despite the extent of academic misconduct and its association with other forms of dishonesty, little else is known about the problem in Mexico. In order to help fill this void, the present study examined the relationship between life-purpose orientations and academic misconduct among university students in Mexico. Based on a meta-analytic investigation, Krou et al. (2021) concluded that academic misconduct is a motivated behavior with sense of purpose as a key variable that influences students’ goals, drives, and values. Research on purpose has shown that university students’ academic motivations are often informed by their life’s purpose (e.g., Sharma et al., 2021; YukhymenkoLescroart & Sharma, 2020). While conceptualizing the motivational mechanisms that might influence academic misconduct, Murdock and Anderman (2006) emphasized the importance of helping students reflect on their lives’ underlying goals and the overarching question of “What is my purpose? ” (p. 130). We posit that students’ purpose might shape their motivations for pursuing higher education, and, hence, students’ behaviors related to academic misconduct might vary depending on their life purpose orientations. However, more studies are needed to tease out the role of students’ purpose orientations in determining their decision to engage in academic misconduct. Hill et al. (2010) conceptualized purpose orientations as the constellations of multiple but related life goals. Empirical studies on purpose
