Numerical Study on the Extrapolation Method for Predicting the Full-scale Resistance of a Ship with an Air Lubrication System

Frictional resistance comprises more than 60% of the total resistance for most merchant ships. Active and passive devices have been used to reduce frictional resistance, but the most effective and practical device is an air lubrication system. Such systems have been applied in several ships, and their effects have been verified in sea trials. On the other hand, there are some differences between the results predicted in model tests and those measured in sea trials. In this study, numerical analyses were carried out for a model and a full-scale ship. A new extrapolation method was proposed to improve the estimation of the full-scale resistance of a ship with an air lubrication system. The volume of fluid (VOF) method was considered for the numerical models of the air layer. The numerical method was validated by comparing the experimental data on the air layer pattern and the total resistance.

Human Health and Worker Productivity: Evidence from Middle- Income Countries

This study strives to scrutinise the influence of various indicators of health status on labour productivity. It is primarily the worker’s health condition which determines the economic growth rate of a country. The study investigates to what extent these indicators of health influence output per person for 75 middle-income countries (MIC) for 1991-2016. The empirical results exhibit improved health status is associated with increased productivity. Results also reveal that physical capital and education has a positive impact on productivity, whereas participation in the labour force has a negative impact on output per person. An important finding of this study is that the impact of health on productivity is considerably greater in upper-middle-income countries (UMIC) in comparison to lowermiddle-income countries (LMIC). The main findings of the study are robust to other determinants of productivity. This study suggests that policy makers should focus on improving the health in MIC.

EMPIRICAL STUDY OF THE ACCEPTANCE OF ERP SYSTEM IN PUBLIC SECTOR SERVICE-BASED ORGANIZATIONS OF PAKISTAN

Investment on Enterprise Resource Planning (ERP) systems has increasing trend in Pakistani organizations. Acceptance of entirely new technological system such as an ERP seems very critical in these organizations. In this study, the acceptance of ERP system was examined with Technology Acceptance Model (TAM) after the addition of user satisfaction dimension. Data was collected through field survey from 211 ERP end users from the public sector service organizations of Pakistan. For testing measurement and path models, partial least squares structural equation modelling (PLS – SEM) technique was applied. Findings indicate the positive and significant impact of user satisfaction on perceived usefulness (PU) and perceived ease of use (PEOU). In the same lines, PU and PEOU has positive influence on intention to use and finally intention to use positively increases the usage of ERP system in these organizations. Based on the findings, some practical implications were also discussed.
Lipopolysaccharide Affects the Proliferation and Glucose Metabolism of Cervical Cancer Cells Through the FRA1/MDM2/p53 Pathway

Previous studies have found that LPS and FRA1 play opposite roles in cervical cancer. In addition, LPS functions by regulating the expression of FRA1 in many disease models, but there is currently no study of their relationship in the energy metabolism of tumor cells. This study, therefore, investigates the effects of LPS on FRA1-mediated glucose metabolism and the possible mechanisms it may have in cervical cancer cells. We constructed FRA1 stable overexpressing/ empty vector cervical cancer cell lines, where glucose consumption, the level of lactic acid production and the expression of energy metabolism related molecules were detected under the stimulation of LPS. At the same time, the changes in proliferation ability of cervical cancer cells were detected. We discovered that LPS promotes glucose consumption, lactic acid production, pentose phosphate bypass, and inhibits aerobic oxidation, by inhibiting the expression of FRA1; and that LPS promotes the growth of cervical cancer cells. Our results indicate that LPS affects the proliferation and glucose metabolism of cervical cancer cells through the FRA1/MDM2/p53 pathway.
Cocrystals and Salts of Gabapentin: pH Dependent Cocrystal Stability and Solubility

Thirteen new multicomponent crystals (cocrystals and salts) of an anticonvulsant drug gabapentin with various carboxylic acid coformers have been discovered using the reaction crystallization method (RCM). These new forms are characterized by X-ray powder diffraction (XRPD), Raman and infrared spectroscopy, and differential scanning calorimetry (DSC). Crystal structures with 3-hydroxybenzoic acid (3HBA) 1, 4-hydroxybenzoic acid (4HBA) 2, salicylic acid 3, 1-hydroxy-2-napthoic acid (1H2NA) 4, and RS-mandelic acid 5 are also determined. While there is proton transfer from coformer to gabapentin in crystals 3−5, no proton transfer occurs in 1. Partial proton transfer is observed in crystal structure 2. Multicomponent crystals 1−5 are thermodynamically stable and do not transform to gabapentin hydrate in water suggesting that the multicomponent phases have equal or lower solubility than the components. pH has been shown to be an important variable in controlling solubility and stability.

Spatial, Social, and Institutional Determinants of Child Delivery Place in Rural Mozambique*

Whereas the coverage of prenatal care in much of rural sub-Saharan Africa has greatly increased, institutional deliveries continue to lag behind as a substantial share of rural women give birth outside clinic settings and without professional obstetric care. This study uses data from rural southern Mozambique to examine the probability of having a non-institutional delivery as a function of individual and household characteristics, location and characteristics of maternal and child health facilities, and past experiences with clinics. Spatial and multivariate regression analyses are employed to determine both additive and interactive effects of these factors. The results show significant additive effects of selected individual/household characteristics and of spatial/environmental characteristics but no effects of clinic experience. The implications of the results are discussed and steps for future analysis are outlined. * Acknowledgment: The support of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (grants #R21HD048257, R01HD058365 R01HD058365-03S1) is gratefully acknowledged.
Knowledge, attitude and practice towards scientific research among undergraduate students of a medical college in Delhi

Medical education in India over a period has largely remained unchanged with a very low emphasis on research and publication. Research, as we know, forms an important foundation for producing doctors with an understanding of evidence-based medicine. This anomaly in education is quite prominently visible at UG level than PG with very little research opportunities available. For PG; there are still some relevant opportunities to conduct research. Scientific research is defined as systematic collection, interpretation and evaluation of data in a planned manner. Indian council of medical research is the apex body for promoting medical research in India, who started their STS program to increase aptitude for medical research. The number of students availing STS has progressively increased from 495 in 2005 and 613 in 2007 to 889 in 2008. Various studies have shown that performing research allows medical students to gain critical thinking skills, ability to evaluate literature, ABSTRACT
Isolation and Identification of Mycotoxigenic Organisms in Poultry Feed from Selected Locations in Abia State, Nigeria

Feed contamination by fungi can lead to nutrient losses and detrimental effects on animal health and production. This present study was designed to isolate and identify the mycological contamination of poultry feeds in some selected parts of Abia state (farms and feed depots in Umuahia north, Osisioma and its environs). A total of 120 samples were collected and used for the study. The samples were screened and processed using spread plate technique. The isolates were identified using slide culture technique. From the samples collected, the fungi contamination in feed samples from depots in Umuahia was 50%, Osisioma 78% and in farms it was 85%. Five fungi organisms were isolated from the feed sample which includes Aspergillus, Penicillium, Fusarium, Original Research Article Nwiyi et al.; AJRAVS, 3(4): 1-9, 2019; Article no.AJRAVS. 50095 2 Mucor and yeast which were seen in almost all the feed samples. Aspergilllus (87%) recorded the highest percentage occurrence, followed by Penicillium (27%), Fusarium (24%), yeast (5%) and Mucor (2%). The total fungi load was significant at 2.0 × 10 5 CFU/g=1 for feed samples from Umuahia North Local government Area, 7× 10CFU/g=1 from Osisioma feed depot and 1× 10 6 CFU/g=1 from poultry farms thereby making the feed samples unsafe for poultry consumption. Therefore, there is need for screening of feeds in these locations in Abia state due to its high fungal load and percentage contamination.
Determination of optimum temperatures and activation energies of inulin hydrolysis by endo-inulinase Aspergillus niger

The paper presents a comparative analysis to determine the optimal temperatures and the activation energies for various origin endo-inulinases from Aspergillus niger. The parameters were estimated based on the literature of the activity curves vs. temperature for hydrolysis of inulin. It was assumed that both the hydrolysis reaction process and the deactivation process of endo-inulinase were first-order reactions by the enzyme concentration. A mathematical model describing the effect of temperature on endo-inulinases from Aspergillus niger activity was used. Based on the comparison analysis, values of the activation energies Ea were in the range from 23.53 ± 3.20 kJ/mol to 50.66 ± 3.61 kJ/mol, the deactivation energies Ed were in the range from 88.42 ± 5.03 kJ/mol to 142.87 ± 2.75 kJ/mol and the optimum temperatures Topt were obtained in the range from 317.12 ± 0.83 K to 332.55 ± 0.72 for endo-inulinase A. niger.
How to Predict Recidivism in Young Offenders: Comparing Logistic Regression, Random Forest, and Boosted Classification Trees and Examining Possible Risk Factors

One important goal of a young offender institution in Germany is to encourage the young offenders (YO) to not commit another crime in the future. In order to enhance the effectiveness of interventions that aim at this goal, research is needed concerning the question under what circumstances a YO recidivates. Traditionally, logistic regression is used in order to analyze recidivism data. Here it is argued that the use of tree-based statistical methods might yield new insights for the prediction of recidivism. It is hypothesized that boosted classification trees yield better predictions than random forest, and that random forests yield better predictions than logistic regression. This study involved 643 YO that were released from the German young offender institution Regis-Breitingen. Predictors included in this study were demographic information, the interventions a YO participated in, an assessment by professionals and a self-assessment. The outcome criterion was whether or not the YO received a new court decision (except for acquittal) within two years after release. The results showed that there was no difference in predictive performance between the methods. All methods performed poorly. Static risk factors for recidivism were younger age and a shorter amount of time spent in the young offender institution. Dynamic risk factors for recidivism included the YO having no place in work, vocational training or school after release, having a need to continue structured transition management after release as well as having participated in delictor problem specific measures. A possible reason for poor predictive performance is heterogeneity of the YO. Implications for further research and policy making are discussed.
Trends and practices in prescribing anti-psychotropic medications in hospitalized patients with psychiatric disorders in a secondary care hospital in Ras al Khaimah

Background: Advances in the psycho-pharmacotherapy enhance the development of newer and better drugs in the management of psychiatric disorders. However, their proper utilization, safety and efficacy and adverse effects in the clinical practice needs continuous study. The study aimed to assess the trends and practice of prescribing psychotropic medications in hospitalized patients in a secondary care hospital in Ras Al Khaimah. Methods: A prospective observational study was carried out for a period of six months in a psychiatry department. All the patient details including the demographic data and prescribing pattern of antipsychotic medication were collected from the patient case records and were later analysed by using descriptive statistics. Results: A total of 50 patient’s prescription were analysed during the study period. Male (54%) predominance was noted over females (46%) with majority (64%) of patients were in the age group of 21-40 years. Schizophrenia (35.8%) was the most common psychiatric disorders followed by affective disorders (30.86%). The average number of psychiatric drugs per prescription was found to be 3.38±1.23. Antipsychotics (43.36%) were the commonly prescribed class of medications followed by mood stabilizers (12.38%) and anxiolytics (11.06%) with olanzapine (n=26), sodium valproate (n=21) and clonazepam (n=9) being frequently prescribed medications. Escitalopram (n=9) was the most commonly used anti-depressants. Combination therapy (86%) is preferred over monotherapy (14%). Conclusions: This study helps to assist in ensuring rational drug therapy and reducing the incidence of drug related problems and medication errors and thereby enhancing the quality of care in patients with psychiatric disorders.
TRADITIONAL STUDY AND SEROPREVALENCE OF THEILERIA SPP. IN CAMELS IN MIDDLE OF IRAQ (WASIT, AL-QADISIYAH AND AL-NAJAF ALASHRAF)

The aim of this study was to identify and diagnosis of Theileria spp. in camels, based on microscopic examination and serological diagnosis by using indirect enzyme-linked immunosorbent assay (iELISA). The period of study was extended from 1 December, 2018 to 31 August, 2019, a total of 270 blood samples were collected from camels of both sexes, with different ages. Blood samples were collected from massacres and herds scattered in three provinces of Wasit, Al Qadissiyah and Al Najaf Al Ashraf in middle of Iraq. The microscopic examination revealed Theileria infection rate 28.88%. On the other hand the percentage of infection by Theileria spp. based on the serological diagnosis was recorded to be 59.70%. In addition statistically was recorded higher rates at >6 years (31.85%) than <6 years (21.95%) with significant differences (P<0.05). The prevalence was 15(22.38%) in male, whereas in female it elevated to 63(31.03%). The difference in prevalence due to sex was significant (P< 0.05). The results showed that the high prevalence in camel could increase the likelihood of the transmission of blood parasites diseases to other animals. Also it is very important to adopt new methods for camel prevention from protozoan blood infection as well as, the promotion and education to the risk of blood parasites for camel and others animals.
Modeling of combined discrete/continuous processes

The dynamic behavior of processing systems exhibits both continuous and significant discrete aspects. Process simulation is therefore a combined discrete/continuous simulation problem. In addition, there is a critical need for a declarative process modeling environment to encompass the entire range of processing system operation, from purely continuous to batch. These issues are addressed by this article. A new formal mathematical description of the combined discrete/continuous simulation problem is introduced to enhance the understanding of the fundamental discrete changes required to model processing systems. The modeling task is decomposed into two distinct activities: modeling fundamental physical behavior, and modeling the external actions imposed on this physical system. Both require significant discrete components. Important contributions include a powerful representation for discontinuities in physical behavior, and the first detailed consideration of how complex sequences of control actions may be modeled in a general manner.
USING OF TRADITIONAL AND QUANTITATIVE CYTOCHEMICAL METHODS FOR IDENTIFICATION AND ENZYME CHARACTERIZATION OF SOME E.COLI SEROGROUPS CAUSING ENTERITIS IN BUFFALOES

Received at: 1/6/2014 Accepted: 11/8/2014 Enteritis is most fatal disease especially for neonatal and young buffalo calves. Out of 150 fecal samples, 100 from diarrheic and 50 from non diarrheic (apparently healthy) buffalo calves were collected from private farms for isolation and identification of E.coli using morphological, cultural, biochemical and serological examination. Further cytochemical enzyme characterization of the different identified serogroups were carried out through the cytochemical quantitative determination of bacterial mitochondrial Adenosene-tri phosphatase (ATP-ase) and succinic dehydrogenase (SDH-ase) enzyme activities for their possible variations among the isolated and identified E.coli serogroups. Four values to each of E.coli serogroup (2 for each enzyme) as optical densities (OD.) could be obtained : (ATPase activity & Actual ATP-ase reaction and SDH-ase activity & Actual SDH-ase reaction) for E.coli-serogroups: E.coli O26, E.coli O55, E.coli O78, E.coli O86 and E.coli O111 as following: (0.595 & 0.285 and 0.560 & 0.210), (0.565 & 0.265 and 0.550 & 0.200), (0.590 & 0.255 and 0.540 & 0.190), (0.590 & 0.205 and 0.490 & 0.180) and (0.600 & 0.160 and 0.560 & 0.150) nm respectively. It was observed that the SDH-ase enzyme activity differentiate between the majority of the studied E.coli-serogroups for the significant (P≤0.05) variations between their enzyme activities (except between the serogroups E.coli O26 and E.coli O111 which showed the same (non-significant) SDH-ase activity, but ATP-ase enzyme activity could not differentiate between the different E.coli serogroups because of its non-significant variations among different serogroups (except with the serogroup E.coli O55 which showed the significant lower ATP-ase enzyme activity and noted to be lower pathogenic than the other E.coli serogroups), so that the actual ATP-ase enzyme activities (the difference between the OD. after and before incubation period) may be used for differentiation between different serogroups. Further cytochemical characterization to other bacterial enzymes and to other E.coli serogroups should be carried out as additional tool for a definite differentiation and characterization of E.coli serogroups causing enteritis in buffalo calves.
Speeding behaviour of adolescents and the image of a typical person who speeds

The aim of this study was to increase our understanding of what motivates young people to take risks in traffic but also why young men are more likely to get involved in road crashes. The participants aged 16-19 years (N=945) completed an online survey. The questions were influenced by the Theory of planned behaviour (TPB) and the Prototype willingness model (PWM) and included a scenario describing a person riding a moped at 65 km/h in an urban area, in which the speed limit
