Influence of Demographic Variables on Immigrants Health Status

The aim of this empirical investigation is to assess Bangladeshi temporary migrant’s general health status in Malaysia and factors affecting their health. The study was carried out through the quantitative method. A survey was conducted among 300 Bangladeshi migrant workers from construction, manufacturing and service sectors. The result indicates that the Bangladeshi temporary migrant workers reported positive self-reported health status with percentages good, very good and excellent. It was also found that the construction and service sector workers reported slightly better health status than manufacturing workers. Result showed that married workers have more health problems than singles. In addition, the low level of education creates more health problems among Bangladeshi workers. It was found that highly educated Bangladeshi workers are more likely to safeguard a sound health status. This study suggest considering Bangladeshi immigrants’ health behaviours, health status and health needs, there should be early health promotion and necessary prevention and/or intervention to improve their health conditions.
Antioxidant Activity and Effect of Sa-khan (Piper, Piperaceae) on the Normal Human Proximal Tubular Epithelial Cell Line

The oxidative damage to proximal tubular epithelial cells may lead to renal dysfunction. This research aimed to investigate antioxidant activity of the Sa-khan crude extract (SCE) and evaluated its effect on cell viability of proximal tubular epithelial cells. The total phenolic content of the SCE was determined using Folin-Ciocalteu method. The free radical scavenging activity of the SCE was investigated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. The effect of the SCE on HK-2 cells, the human proximal tubular epithelial cell line, was investigated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The SCE showed the total phenolic content of 17.35 ± 0.40 mg GAE/g extract. In addition, the SCE exhibited scavenging activity on DPPH (IC50 = 1.15+0.071 mg/mL). Moreover, eleven spots of antioxidant compounds were detected when the two-dimensional thin-layer chromatography combined with the DPPH spray technique was performed. Furthermore, the SCE at the concentration of 0.125 mg/mL could promote the proliferation of HK-2 cells over various durations. Together, these results indicate that the SCE may contain compound(s) with potential health benefits. Keywords: Sa-khan, normal human proximal tubular epithelial cell, antioxidant activity
Arbuscular Mycorrhizal Fungi as Potential Agents in Ameliorating Heavy Metal Stress in Plants

Heavy metal accumulation in plants is a severe environmental problem, rising at an expeditious rate. Heavy metals such as cadmium, arsenic, mercury and lead are known environmental pollutants that exert noxious effects on the morpho-physiological and biological attributes of a plant. Due to their mobile nature, they have become an extended part of the food chain and affect human health. Arbuscular mycorrhizal fungi ameliorate metal toxicity as they intensify the plant’s ability to tolerate metal stress. Mycorrhizal fungi have vesicles, which are analogous to fungal vacuoles and accumulate massive amount of heavy metals in them. With the help of a pervasive hyphal network, arbuscular mycorrhizal fungi help in the uptake of water and nutrients, thereby abating the use of chemical fertilizers on the plants. They also promote resistance parameters in the plants, secrete a glycoprotein named glomalin that reduces the metal uptake in plants by forming glycoprotein–metal complexes, and improve the quality of the soil. They also assist plants in phytoremediation by increasing the absorptive area, increase the antioxidant response, chelate heavy metals and stimulate genes for protein synthesis that reduce the damage caused by free radicals. The current manuscript focuses on the uptake of heavy metals, accumulation, and arbuscular mycorrhizal impact in ameliorating heavy metal stress in plants.
Spring and autumn phenology in sub-mesothermal beech stands from the southwestern extremity of the Carpathians

The research carried out was aimed at assessing the phenological behavior of beech (Fagus sylvatica L.) in the southwestern area of the Carpathians, in sub-mesothermal forest sites, which are different from the majority mesothermal ones of this species. The data obtained can be used for predicting the phenological changes of the species, especially in the Carpathian area, under the future influence of expected climate change. Assessments for spring and autumn phenology (buds burst-BB and foliation, flowering and leaves senescence) were carried out in 3 phenological research areas located at 200 m, 700 m and 1200 m. At each altitude level, 100 trees of I and II Kraft classes were phenologically characterized: 50 trees on the south-facing slope (sunny exposure) and 50 on the north-facing slope (shade exposure). The phenological data were interpreted in relation to climate data (average temperature) recorded in each area by a HOBO U23 Pro v2 sensor. The site conditions of sub-mesothermal climate in the low altitude area led to DOY (day of the year) for BB (buds burst) values below 100. The phenological differentiation of populations is evident in relation to the altitude, while the influence of the exposure is much lower. The gradient values based on altitude sectors highlighted the nonlinearity of the development of foliation phenophase: 1.6 days/100 m at low altitude, where the beech is under the impact of the sub-mesothermal climate and 4.4 days/100 m between 700 and 1200 m altitude. Thus, it has been proven that the foliation onset depends on the cumulation of temperatures in relation to the DOY moment and on the values recorded throughout the vegetative rest. The altitudinal gradient values which are influencing the flowering also differentiate the stands. The leaves senescence has a delay of 1.8 up to 2.4 days per 100 meters altitude, and the length of the vegetation season is reduced more sharply in the upper half of the analyzed altitudinal transect. Our data may be used for predicting the phenological changes, especially in the Carpathian area, under the expected climate change.
Utilisation of raw palm oil mill effluent (POME) as a renewable substrate for fermentative H2 production: Optimisation using statistical approach

Fermentative H 2 production was studied using raw POME as the substrate with heat-shock pre-treated POME anaerobic sludge acted as the inoculum. The effect of crucial operating variables (initial pH of medium, incubation temperature, and inoculum size) on H 2 production was studied using Box−Behnken Design. A second-order polynomial regression model was generated to evaluate H 2 production trend under conditions tested. The model analysis revealed the high significance of linear effects of initial pH, incubation temperature, and inoculum size ( P < 0.01) towards H 2 production. Similar results indicated that the interaction effect between initial pH and inoculum size, and interaction effect between incubation temperature and inoculum size were highly significant ( P < 0.01). The regression model suggested that the optimum conditions were set to a pH value, incubation temperature and inoculum size of 6.4, 58.0°C and 8.0% v/v, respectively. In order to validate the optimum conditions determined by the model, heat-shock pre-treated POME anaerobic sludge was incubated with raw POME under optimum conditions. Validation experiment showed that a cumulative H 2 volume of 239.0 mL was produced. Microbial community analysis of inoculum showed that mixed consortia between Clostridium sp. and other obligate anaerobic non-spore forming bacteria, mostly belonging to the Firmicutes and Bacteroidetes phyla were identified as the major H 2 -producers and were hugely responsible towards fermentative H 2 production.
Detection of Streptococcus pneumoniae in Sputum Samples by Real-Time PCR

Conventional laboratory culture-based methods for diagnosis of Streptococcus pneumoniae are time-consuming and yield false negative results. Molecular methods including real-time (RT)-PCR rapid methods and conventional PCR due to higher sensitivity and accuracy have replaced traditional culture assay. The aim of the current study was to evaluate lytA gene for the detection of Streptococcus pneumoniae in the cerebrospinal fluid of human patients with meningitis using real-time PCR assay. In this cross-sectional study, a total of 30 clinical specimens were collected from patients in a period from September to December 2018. In order to evaluate the presence of lytA gene, conventional and real-time PCR methods were used without culture. From 30 sputum samples, five (16.66%) isolates were identified as S. pneumoniae by lytA PCR and sequencing. In this research, an accurate and rapid real-time PCR method was used, which is based on lytA gene for diagnosis of bacteria. Based on the sequencing results, the sensitivity for the detection of lytA gene was 100% (5/5).
Translation Resilient Opportunistic WiFi Sensing

Passive wireless sensing using WiFi signals has become a very active area of research over the past few years. Such techniques provide a cost-effective and non-intrusive solution for human activity sensing especially in healthcare applications. One of the main approaches used in wireless sensing is based on fine-grained WiFi Channel State Information (CSI) which can be extracted from commercial Network Interface Cards (NICs). In this paper, we present a new signal processing pipeline required for effective wireless sensing. An experiment involving five participants performing six different activities was carried out in an office space to evaluate the performance of activity recognition using WiFi CSI in different physical layouts. Experimental results show that the CSI system has the best detection performance when activities are performed half-way in between the transmitter and receiver in a line-of-sight (LoS) setting. In this case, an accuracy as high as 91% is achieved while the accuracy for the case where the transmitter and receiver are co-located is around 62%. As for the case when data from all layouts is combined, which better reflects the real-world scenario, the accuracy is around 67%. The results showed that the activity detection performance is dependent not only on the locations of the transmitter and receiver but also on the positioning of the person performing the activity.

A study on pattern of placentation in post caesarean pregnancy

During the past few decades the world wide incidence of caesarean births has increased markedly. Approximately 1 out of 4 women will have a caesarean delivery and it is the most frequently performed surgical procedure in the United States. World wide variation exists in rates for caesarean delivery; currently range from 10-40% of all deliveries, whereas WHO has suggested that there is no increase in health benefits associated with caesarean rates more than 10-15%. About 1/3 of the caesarean sections are repeat procedures. Repeat caesarean sections are associated with increased morbidity, but little has been done to investigate the complications that are specifically associated with repeat caesarean sections. Perhaps the greatest risk to future pregnancies is an increase in disorders caused by abnormal placentation including placenta previa, placenta accreta.
Hur motiverar gymnasieelever sina bedömningar av trovärdiga och vilseledande digitala nyheter

In this study, we investigate how ca. 400 students, age 16-19, determine the trustworthiness of false, biased and credible news. We examine their justifications of their assessments of the credibility with regard to the source (who? ), the content (what? ), the design (how? ) and the underlying purposes (why? ). We find that students’ patterns of justifications can be linked to different assessments. For example, students finding junk news credible may have special problems separating different kinds of sources. Students who fail to debunk a manipulated image often rely on what they see in the image in contrast to students who determine credibility upon what is not in the image. We also find that testitems used in previous research can be linked to aspects of civic online reasoning not identified in previous research. We identify complex potentials and pitfalls among students important for education and further research.
The Role of Renewable Energy Resources in Sustainability of Water Desalination as a Potential Fresh-Water Source: An Updated Review

Desalination is becoming a practical option to meet water demand in an increasing number of locations that are facing water scarcity. Currently, more than 150 countries in the world are already using desalination technologies, which account for about one percent of the world’s drinking water. Although for specific regions, desalination is the only feasible solution to close the supply–demand gap (for example the production of desalinated seawater in the Middle East is predicted to rise almost fourteen-fold by 2040), the sustainability of desalination systems is still remarkably under question. This review aims first to investigate the technical and economic trends and environmental and social aspects of desalination systems and then, in the second stage, to give an overview of the role of renewable energy technologies in the sustainability of the future water systems with an increasing share of desalination.
Development of Lightweight Concrete using Industrial Waste Palm Oil Clinker

Concrete is a major material used in the construction of buildings and structures in the world. Gravel and sand are the major ingredients of concrete but are non-renewable natural materials. Therefore, the utilisation of palm oil clinker (POC), a solid waste generated from palm oil industry is proposed to replace natural aggregate in this research to reduce the demand for natural aggregates. One mix of ordinary concrete as control concrete; while four mix proportions of oil palm clinker concrete were obtained by replacing 25 %, 50 %, 75 %, and 100 % of gravel and sand of control concrete with coarse and fine oil palm clinker respectively by volume, with same cement content and water cement ratio. Compressive strength test was carried out of concretes with different percentages of oil palm clinker; whereas water absorption test according to respective standard, were carried out to determine the durability properties of various mixes. Based on the results obtained, the study on the effect of percentage of clinker on strength and durability properties was drawn. According to ACI classification of light weight concrete only the 100 percentage replacement can achieve the definition of light weight concrete since its density less than 1900 kg/m3 and strength larger than 17 MPa. Eventually the 25 % replacement of the normal aggregate by the OPC will improve the strength and durability of the concrete.

An Autonomous Home Energy Management System Using Dynamic Priority Strategy in Conventional Homes

With the growth in smart technology, customers have a chance to contribute to demand response programs and reduce their bills of electricity actively. This paper presents an intelligent wireless smart plug demonstration, which is designed to control the electrical appliances in the home energy management system (HEMS) application with a response to the utility company’s signal. Besides, a linear model of an energy management system utilizing a dynamic priority for electrical appliances is used as an energy management strategy. This can be useful for decreasing energy consumption in peak hours. Proposed hardware is tested with two different price strategies such as real-time pricing and a combination of this and incremental block rate (IBR) pricing. A small one-story house with ordinary electrical appliances is used as a test-bed for the proposed hardware and strategy. Initial results show that intelligent plugs can decrease the energy cost by 9% per day with an effective peak-to-average ratio deduction compared to the domicile without deploying intelligent plugs and controllers.
Accelerating the development of phase‐change random access memory with in‐fab plasma profiling time‐of‐flight mass spectrometry

We demonstrate the potential of using plasma profiling time‐of‐flight mass spectrometry (PP‐TOFMS) to accelerate process developments for phase‐change random access memory (PCRAM) applications, which require advanced materials with composition‐driven properties. We assess the performances of PP‐TOFMS for the chemical depth‐profiling of GeSbTe phase change materials, first after deposition steps to investigate the top surface layer and the incorporation of silicon into the amorphous matrix, then after the thermal annealing step to refine in situ capping strategies, and finally in close loop with etching process steps. Comparison of reference‐free semiquantitative PP‐TOFMS analysis based on ion beam ratio with Rutherford backscattering spectrometry shows remarkable agreement (~10% relative). PP‐TOFMS proves to be a fast screening tool, which allows process monitoring and selection of samples that indeed need more complex analysis.
Successful business models for service centres: an empirical analysis

PurposeThe purpose of this paper is to analyse the fit between the strategy of service centres and their business model (BM) and to identify the BM components' characteristics and links that allow it to stand out in terms of service delivery and business performance.Design/methodology/approachThis study applies an inductive qualitative multiple case study approach through the empirical analysis of top-performing Italian service centres operating in the Medium–Heavy Commercial Vehicle sector.FindingsResearch findings underline that the BM components of top performers are consistent amongst each other and with the adopted strategy and make a positive impact on the firm's performance. In particular, top performers are characterised by a solid financial structure based on equity, formalised and flexible organisational structures and processes, clarity in strategic direction and long-term orientation, grounded capabilities, competences and skills, trustful relationships with main service partners and a comprehensive set of managerial mechanisms.Research limitations/implicationsThis paper presents some limitations, typical of qualitative research based on case studies. Future works may include other dimensions of performance for identifying top performers, and extend the empirical analysis to different sectors and national contexts.Originality/valueThis paper supports the relevance of contingency theory – particularly the strategy-structure-performance paradigm – in the analysis of the role of a BM in successful servitization strategies of service centres. It highlights that the BMs of the top-performing companies are characterised by some common elements. From a practical perspective, the authors provide insights that can be useful for designing successful service-based BMs for service networks.
A New Framework of IND-CCA Secure Public Key Encryption with Keyword Search

In the era of cloud computing, public key encryption with keyword search (PEKS) is an extremely useful cryptographic tool for searching on encryption data, whose strongest security notion is indistinguishability encryption against chosen ciphertext attack (ind-cca). Adballa et al. presented a transformation from identity based encryption (IBE) to PEKS in the Theory of Cryptography Conference 2010. This paper proposes a new framework of ind-cca secure PEKS in the standard model. Our main technical tool is a newly introduced notion of smooth projective hash function with key mapping, in which the hash key hk is mapped into another mapping projection key mhp besides the classical projection key hp. Finally, we provide an instantiation of our framework based on symmetric eXternal Diffie–Hellman assumption.
