Influence of Side Spoilers on the Aerodynamic Properties of a Sports Car

This paper discusses the capabilities of side spoilers to improve the aerodynamic properties of a sports car exposed to a non-zero yaw angle flow. In such conditions, the aerodynamic drag and lift both increase with the introduction of a side force and a yawing moment, which contribute to the decrease of the car’s handling properties and force the car to change its driving path. Elements mounted on the side of the car make it possible to obtain an asymmetric aerodynamic load distribution and generate additional forces that can be used to counter these effects. The performance of the side spoilers was analyzed at yaw angles ranging from 0° to 15° using the results of numerical calculations. It was established that the side spoilers made it possible to generate at low yaw angles aerodynamic forces that exceeded those caused by a crosswind.
The complete mitochondrial genome of Amphiesma optatum

Abstract In this study, we obtained and described the complete mitochondrial genome sequence of Amphiesma optatum. The total length is 17,259 base pairs. Similar to most Colubridae mitochondrial genomes, there are 37 genes including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), and 2 ribosomal RNA genes (rRNA). In addition, it contains two control regions (D-loop) rich in A–T base. The total base composition of mitochondrial DNA is 34.3% for A, 26.5% for C, 12.8% for G, and 26.4% for T, and the percentage of GC content is 39.3%. These data further reveal the phylogenetic relationship between Amphiesma optatum and other species in the Colubridae family.

The significance of context and victim–offender relationship for Swedish social workers’ understandings of young men’s violent victimization

This article investigates how social workers’ interpretations of contextual factors and the relationship between victim and offender affect their understanding and assessment of male violent victimization. The study was designed as a multiple case study with a qualitative comparative approach. Focus group interviews supported by vignettes were used to collect data. Interviews were carried out with professional Swedish social workers working with victimized men and women at support units for young crime victims in Sweden. The results show that the social workers consider the violence that the young men are subjected to in cases of street violence and interpersonal violence to be unavoidable or even ‘natural’. The violence was in some cases considered to be dependent on the men’s own agency and in others on their lack of agency, when displaying traits of both more traditional and less traditional forms of masculinity respectively. The social workers’ talk about young male crime victims is interpreted as contributing to making the men appear as less legitimate victims. Even though the social workers argued that the victims’ own behaviour should not lead to any special considerations concerning help efforts, the possibility of upholding such a demarcation between explanations ascribed to the violent incident and help measures offered is problematized in the article.
Multi-objective evolutionary algorithm on simplified bi-objective minimum weight minimum label spanning tree problems

As general purpose optimisation methods, evolutionary algorithms have been efficiently used to solve multi-objective combinatorial optimisation problems. However, few theoretical investigations have been conducted to understand the efficiency of evolutionary algorithms on such problems, and even fewer theoretical investigations have been conducted on multi-objective combinatorial optimisation problems coming from real world. In this paper, we analyse the performance of a simple multi-objective evolutionary algorithm on two simplified instances of the bi-objective minimum weight minimum label spanning tree problem, which comes from real world. Though these two instances are similar, the analysis results show that the simple multi-objective evolutionary algorithm is efficient for one instance, but it may be inefficient for the other. According to the analysis on the second instance, we think that the restart strategy may be useful in making the multi-objective evolutionary algorithm more efficient for the bi-objective problem.
EXTENDED UTAUT2 MODEL ON FACTORS INFLUENCING OF MOBILE COMMERCE ACCEPTANCE IN YANGON, MYANMAR

Today, wireless telecommunication is well designed and there is significant evidence on the critical growth of wireless technologies in developing countries including Myanmar. However, the usage of mobile services and transactions such as mobile payment, mobile wallet, electronic business are still low in Myanmar. This research attempts to investigate the factors influencing Mobile Commerce acceptance in Yangon, Myanmar and examines the differences in acceptance level among three generation groups (Generation X, Generation Y and Generation Y). A conceptual framework was developed based on an extended Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) for M-Commerce, and two additional variables such as disturbance concerns and perceived trust on behavior intention on use of M-commerce. A survey data was collected from 405 the respondents who owned the mobile phone with M-Commerce knowledge in Yangon, Myanmar by using judgmental, quota and convenience sampling methods. The Simple and Multiple Linear Regression and One-Way ANOVA were used. Findings indicated that the five independent factors such as performance expectancy, social influence, facilitating conditions, price/value, habit from technology acceptance theory positively significantly influence the behavioral intention towards MCommerce acceptance. The two extended variables such as disturbance concerns negatively significantly, and perceived trust positively significantly influence the behavioral intention towards M-Commerce acceptance. Among significant factors, habit is the most influencing on M-Commerce acceptance and Generations such as X and Y are sensitive on trust while using M-Commerce.
Indonesian kalkulator of oocytes (IKO): A smart application to determine our biological age

Background: The use of smartphones and its associated application provides new opportunities for physicians. In current situations, there are still few applications are designed in the field of infertility and Assisted Reproductive Technologies (ART). A study conducted on 1616 subjects proved that AMH (Anti-Mullerian Hormone) could be used to predict a woman’s biological age earlier than Follicle-Stimulating Hormone (FSH) and Antral Follicle Count (AFC). In this study, we describe the AMH nomogram that has been developed into a mobile application as “Indonesian Kalculator of Oocytes” (IKO). The software required to create IKO application was the Android 4.0. 3 Ice Cream Sandwich and Java Application Development. The hardware specification that needed to develop the IKO apps were a 4.0-inch screen, 512 MB RAM (random-access memory), and CPU (central processing unit) with dual core 1.2 Ghz. The application is built using the Android SDK (Software Development Kit) and Java Application Development. In this app.
Ceramic Binder Jetting Additive Manufacturing: A Literature Review on Density

The objective of this review paper is to summarize the current status and identify the knowledge gaps in ceramic binder jetting additive manufacturing, with a particular focus on density. This paper begins with an overview of ceramic binder jetting. Then, it discusses different aspects of density, including various terminologies, measurement methods, and achieved values. Afterward, it reviews two categories of techniques to increase the part density: material preparation techniques (powder granulation, mixing powders of different sizes, using slurry feedstock, and mixing different materials) and postprocessing techniques (sintering, chemical reaction, infiltration, and isostatic pressing). Finally, it presents the knowledge gaps in the literature.
Approach of Electrostatic Interaction Based Layer-by-Layer Assembly of Cationic Guar Gum and Poly (Carboxylic acid)

The present study evaluated the possibility to form thin film of cationic guar gum (CGG) associated with poly (carboxylic acid) such as carboxymethyl cellulose (CMC) and poly (acrylic acid) (PAA) through layer-by-layer (LbL) assembly. The thin film thickness and morphology show dependence on pH value, ionic strength and temperature. For pH 3 to pH 4 CGG and poly (carboxylic acids) assemble and form thin film through LbL. For neutral pH region and high pH values CGG and poly (carboxylic acids) do not interacted. In contrast to synthetic polyelectrolyte complex thin film, such as polystyrene sulfonate (PSS)/ poly (diallyldimethylammonium chloride) (PDDA) and PSS/ poly (allylamine hydrochloride) (PAH), the LbL assembly of CGG/CMC and CGG/PAA take place only at low salt concentrations. Deposition at high temperature (up to 60°C) results thicker CGG/ poly (carboxylic acids) films.
Satisfaction with Life Scale: New Psychometric Evidence in a Romanian Emerging Adults Sample

The purpose of the article was the adaption and the validation of Satisfaction with Life Scale in correlation with measures of the curiosity and the Big Five personality traits in the case of a sample of emerging adults. In addition to SWLS, we applied inventories for curiosity (CEI-II) and Big Five personality traits (BFI-10) on a group of students emerging as adults (N = 520; age = 19,70). Both the exploratory factor analysis and the confirmatory factor analysis showed an adequate fit of a single-factor model (χ2/df = 2,19; CFI = .99; RMSEA = .049). This structure was confirmed by a multigroup confirmatory factor analysis and gender invariant. SWLS shows acceptable internal consistency (α = .79). Supporting its criterion-related validity, the SWLS correlated positively with curiosity and its factors, stretching and embracing, with all the personality traits, extraversion, agreeableness, conscientiousness, except for openness, and negatively with neuroticism. The results show that SWLS is fit for the work with emerging adults.

Renal dysfunction in HIV positive patients on highly active antiretroviral therapy (HAART)

BACKGROUND: The use of HAART has turned HIV/AIDS into a chronic disease and people live longer. They now present with complications related to the treatment, ageing process and the virus itself. Renal dysfunction is a recognized complication in HIV infected patients on HAART and can present as acute kidney injury or chronic kidney disease. METHODS: A cross sectional study was conducted at Parirenyatwa Hospital on patients receiving HAART. Inclusion criteria were age â‰¥ 18 years and provision of an informed consent. Clinical data was recorded. Body mass index, CD4 count, serum creatinine, urine for dipstick proteinuria and protein: creatinine ratio was collected. Creatinine was calculated using the Cockcroft-Gault formula. Renal dysfunction was defined as Creatinine clearance (CrCl)< 60mL/min. RESULTS: A total of 122 patients with complete data were analysed. 69% were females. Mean age of patients was 37.7 Â±11.3 years and Body mass index was26.0 Â±5.2 kg/mÂ². Renal dysfunction defined as CrCl< 60mL/min was found in 18.9 %,(n =23/122). Microalbuminuria was found to be a risk factor for renal dysfunction [OR 4.24 95% CI 1.00-17.04] p < 0.049. CONCLUSION: Renal dysfunction is common among patients on HAART and micro albuminuria is a risk factor for developing renal dysfunction. For patients on HAART routine urine protein: creatinine ratio and calculation of creatinine clearance should be done at regular intervals to monitor if the patients are developing renal dysfunction.
Performance Analysis of IEEE 802.11p for Continuous Backoff Freezing in IoV

With the rapid development of cloud computing and big data, traditional Vehicular Ad hoc Networks (VANETs) are evolving into the Internet of Vehicles (IoV). As an important communication technology in IoV, IEEE 802.11p protocols have been studied by many experts and scholars. In IEEE 802.11p, a node’s backoff counter will be frozen when the channel is detected as busy. However, most studies did not consider the possibility of continuous backoff freezing when calculating delay. Thus, in this paper, we focus on the performance analysis of IEEE 802.11p for continuous backoff freezing. Specifically, we establish an analytical model to analyze the broadcast performance in the highway scene where vehicles can obtain traffic density from roadside units through Vehicle to Infrastructure (V2I) communications. We first calculate the relationship between vehicle density and the number of vehicles. Then, we derive the relationship between the number of vehicles and packet delay according to Markov chains. Next, we utilize the probability generating function (PGF) to transform traditional Markov chains into z domain under the situation of non-saturation. Finally, we employ the Mason formula to derive packet delay. As compared with the performance without considering the continuous backoff freezing, the simulation results have demonstrated that our analytical model is more reasonable.
Use of conductive zip and Velcro as a polarisation reconfiguration means of a textile patch antenna

Α feasibility study of using components such as conductive Velcro tape and zip fastener to change the polarisation of a textile patch antenna from linear (LP) to circular (CP) is presented. The antennas are designed to operate at 2.3–2.5 GHz frequency band, are made using felt substrate and conductive cloth and their size is 100.4 mm × 74.2 mm × 4.26 mm. It is proved, via simulations and measurements, that such components are strong candidates as means for polarisation reconfiguration of textile antennas. Both Velcro and zip textile patch antennas at the LP mode yield axial ratio (AR) larger than 10 dB at the operating frequency range. In the CP mode, the Velcro antenna gives AR equal to 3.1 dB at 2.35 GHz and the zip antenna 1 dB at 2.31 GHz. Repeatability measurements of interchanging polarisation modes (LP–CP) for both antennas have been conducted presenting acceptable repeatability. Great advantage of both antennas (Velcro and zip) is that the polarisation can be changed at will by a simple manipulation (detach the Velcro or unzip); thus, providing to the user the flexibility of adjusting the antenna characteristics depending on wearable application and environment of operation.
Grassroots innovations in the informal economy: insights from value theory

ABSTRACT The scholarship on innovation hitherto has prioritized exchange value, scalability and large scale commercialization, overlooking the other significant human centric values discussed in 'value theory'. Consequently, innovations in the informal economy are often undermined due to their inability to generate exchange values. This paper identifies and examines the suitability of the nuanced set of values discussed in value theory for informal sector grassroots innovations. Based on ten years of ethnographic research in different parts of Jammu and Kashmir in India, we find that these innovations generate a diverse set of values, ranging from use value to socially embedded reciprocal exchange value to different forms of relational and non-relational intrinsic values. At a juncture when strengthening alternative innovation approaches occupies a priority, these findings have important bearing on innovation policy scholarship.
Severe Hand Foot and Mouth Disease in Vietnamese Children: Clinical Features and Management Strategies

Hand, Foot and Mouth Disease (HFMD) plays a major role in childhood morbidity and mortality in Vietnam and the Asia-Pacific region. The spectrum of severe disease and predictors for poor outcome are not well understood, and the evidence-base for management of hypertension in severe cases is lacking. In this thesis I describe the clinical features, their evolution over time, and the viral serotype/genotype findings, among 1272 HFMD cases admitted to PICU at the Hospital for Tropical Diseases (HTD), Ho Chi Minh City, during the the 2011-2012 Vietnam outbreak. Fever, skin rash, and myoclonic jerks happened in the early stage while the more severe features, including hypertension, tachypnea, irregular breathing, pulmonary edema and shock occurred after day 3. Most severe features were associated with EV-A71 infection rather than with Coxsackieviruses (CV). However having mouth ulcers without skin lesions was associated with CV infection. The C4 genogroup of EV-A71 was associated with more severe neurological involvement. Risk factors present within 24 hours of PICU admission that were associated with subsequent deterioration to severe outcome were skin lesions and tachypnea, while presence of mouth ulcers alone was protective. I also describe the development and execution of a randomized controlled trial of a novel treatment, MgSO4, for severe HFMD with hypertension secondary to ANS dysregulation. However, only 26 of the planned 190 patients were enrolled before the outbreak was controlled, and with this small number we found no evidence of benefit in this trial. In another approach, I assessed the efficacy of MgOS4 on severe hypertension among 33 patients treated with open-label MgSO4 compared to 12 patients of similar clinical severity who did not receive this intervention, and found a significant reduction in mean arterial pressure among the MgSO4 recipients. However, It is clear that with the small sample size, these data are insufficient to address the important question originally posed. Using our pre-prepared protocol as a basis, a much larger trial could be developed at short notice in the event of another outbreak, to properly evaluate whether MgSO4 has a role in controlling the blood pressure in severe HFMD.
Étude de la transférabilité d'un programme de prévention primaire des blessures du coude au baseball vers le lancer de javelot

Le lancer de javelot predispose les athletes aux blessures du coude. Dans le sport, des programmes de prevention visant a ameliorer la condition physique permettent de diminuer l’incidence des blessures. Cependant, il n’en existe pas concernant celles du coude pour les lanceurs de javelot. La biomecanique du lancer au baseball etant proche de celle du lancer de javelot, ce travail s’interesse aux programmes de prevention de ce sport dans l’optique de les transferer au lancer de javelot. Methodes : une revue de la litterature a ete realisee pour identifier les programmes de prevention primaire des blessures du coude au baseball. Leurs caracteristiques ont ensuite ete analysees pour evaluer leur transferabilite vers le lancer de javelot. Resultats : un seul programme de prevention a ete selectionne : le programme Yokohama Baseball-9 (YKB-9). Discussion-Conclusion : la majorite des facteurs de risque utilises dans le programme YKB-9 correspond au lancer de javelot. Cependant son efficacite a ete montree dans une population possedant des caracteristiques differentes de celles des lanceurs de javelot. De plus, certains facteurs de risque utilises dans ce programme de prevention sont discutables. Au vu de ces elements, une adaptation du programme YKB-9 est proposee pour les lanceurs de javelots.
Business fixed investment of Chinese manufacturing firms in the post-financial crisis era

ABSTRACT I document the investment decline of Chinese manufacturing firms after 2011, following the end of the 4 trillion fiscal stimulus program and expansionary monetary policies for combating the 2008–2009 financial crisis. I employ a difference-in-difference strategy to show that state-owned enterprises (SOEs) acted as investment stabilizers. In the post-crisis era, SOEs’ investment rates fell less compared to their private counterparts. Moreover, they had a smaller chance of exiting the market than private firms. In the face of monetary tightening, SOEs enjoyed a much smaller increase in the interest rates of their long-term debts. Although these may fuel the growth of the SOE sector relative to the private sector, and thus raised concerns for capital misallocation, the adverse effect on reallocation was dampened by shadow banking.
