A High-Resolution Foreground Model for the MWA EoR1 Field: Model and Implications for EoR Power Spectrum Analysis

Abstract The current generation of experiments aiming to detect the neutral hydrogen signal from the Epoch of Reionisation (EoR) is likely to be limited by systematic effects associated with removing foreground sources from target fields. In this paper, we develop a model for the compact foreground sources in one of the target fields of the MWA’s EoR key science experiment: the ‘EoR1’ field. The model is based on both the MWA’s GLEAM survey and GMRT 150 MHz data from the TGSS survey, the latter providing higher angular resolution and better astrometric accuracy for compact sources than is available from the MWA alone. The model contains 5 049 sources, some of which have complicated morphology in MWA data, Fornax A being the most complex. The higher resolution data show that 13% of sources that appear point-like to the MWA have complicated morphology such as double and quad structure, with a typical separation of 33 arcsec. We derive an analytic expression for the error introduced into the EoR two-dimensional power spectrum due to peeling close double sources as single point sources and show that for the measured source properties, the error in the power spectrum is confined to high k ⊥ modes that do not affect the overall result for the large-scale cosmological signal of interest. The brightest 10 mis-modelled sources in the field contribute 90% of the power bias in the data, suggesting that it is most critical to improve the models of the brightest sources. With this hybrid model, we reprocess data from the EoR1 field and show a maximum of 8% improved calibration accuracy and a factor of two reduction in residual power in k-space from peeling these sources. Implications for future EoR experiments including the SKA are discussed in relation to the improvements obtained.
Effects of natural nitrite source from Swiss chard on quality characteristics of cured pork loin

Objective This study was conducted to evaluate quality characteristics of cured pork loin with natural nitrite source from Swiss chard. Methods Pork loin was cured in brine and the ratio of water and fermented Swiss chard (FSC) solution in the brine was changed by 4:0 (control), 3:1 (T1), 1:1 (T2), 1:3 (T3), 0:4 (T4), and pickled samples with 0.012% sodium nitrite (PC, positive control) and nitrite free brine (NC, negative control) were considered as the control. Results The pH values of cured pork loins with FSC were decreased with increasing addition level of FSC. Cooking loss was not significantly different among all treatments. T4 had the lowest value in moisture content and lightness value and the highest value in curing efficiency. The redness value of T4 was not significantly different from that of PC in raw. After cooking, however, it was higher than that of PC. The yellowness value of cured pork loin added with FSC was increased with increasing level of FSC. Volatile basic nitrogen content of cured pork loin added with FSC was higher than PC and NC. Thiobarbituric acid reactive substance value of cured pork loin added with FSC was decreased with increasing FSC level. Residual nitrite level and shear force were increased with increasing FSC level. In the sensory evaluation, sensory score for flavor, off-flavor, chewiness, juiciness, and overall acceptability were not significantly different among all treatments. However, sensory score for color was increased when the concentration of FSC added to pork loin was increased. Conclusion The FSC solution had a positive effect on redness and lipid oxidation. As shown by the results in protein deterioration and sensory, Swiss chard can replace sodium nitrite as natural curing agent.
Predation of the introduced cladoceran Cercopagis pengoi on the native copepod Eurytemora affinis in the northern Baltic Sea

We studied the potential of an introduced species, the predatory cladoceran Cercopagis pengoi, to influence native zooplankton populations in the Baltic Sea. Feeding rates (FRs) of different instars of C. pengoi on Eurytemora affinis, a dominant copepod species, were determined experimen- tally. The FRs of C. pengoi varied from 0.7 to 4.8 prey predator -1 d -1 and were significantly higher in older instars. Based on the experimental results and long-term zooplankton abundance data from the Gulf of Finland, we estimated the in situ predation rates. Our results imply that at maximum abun- dance, the C. pengoi population feeding in dense prey patches could consume as many as 10 5 E. affi- nis m -3 d -1 . This could explain the observed drastic decrease in copepod abundances in the eastern Gulf of Finland, the region with the highest C. pengoi abundance after the expansion of this species. Such a decline may strengthen food competition between other zooplanktivores, i.e. planktivorous fish and mysids, feeding on the same copepod prey in regions where C. pengoi may reach high abun- dances. In the Gulf of Finland, especially in the eastern parts, a collapse of E. affinis, a key species in the pelagic system, would cause major changes in virtually all trophic levels, because the food web structure is simple with only a few species of zooplankton, planktivores, and piscivores.
Pharmacoepidemiology: Using randomised control trials and observational studies in clinical decision‐making

Weighing up sources of evidence is a key skill for clinical decision‐makers. Randomised controlled trials (RCTs) and observational studies each have advantages and disadvantages, and in both cases perceived weaknesses can be improved through modifications of design and analysis. In the field of pharmacoepidemiology, RCTs are the best way to determine whether an intervention modifies an outcome being studied, largely because randomisation reduces bias and confounding. Observational studies are useful to investigate whether benefits/harms of a treatment are seen in day‐to‐day clinical practice in a wider group of patients. Although observational studies, even in a small cohort, can provide very useful clinical evidence, they may also be misleading (as shown by subsequent RCTs), in part because of allocation bias. There is an unmet need for clinicians to become well versed in appraising the study design and statistical analysis of observational pharmacoepidemiology (OP) studies, rather like the medical training already offered for RCT evaluation. This is because OP studies are likely to become more common with the computerisation of healthcare records and increasingly contribute to the evidence base available for clinical decision‐making. However, when the results of an RCT conflict with the results of an OP study, the findings of the RCT should be preferred, especially if its findings have been repeated elsewhere. Conversely, OP studies that align with the findings of RCTs can provide rich and useful information to complement that generated by RCTs.

EFFECT OF SPIRULINA (SPIRULINA PLATENSIS) ADDITION ON TEXTURAL AND QUALITY PROPERTIES OF COOKIES

Nowadays scientists are looking for new food ingredients that are not seasonal and are rich in bioactive compounds, such as microalgae. The aim of this study was to enrich wholegrain cookies with microalgae (Spirulina platensis) powder. 1%, 2% and 3% of spirulina was used to fortify the cookies. Their physical, textural and sensory properties were analyzed. The addition of even small amounts of the microalgae (1%) changed color of the cookies significantly to intensive green. Decrease of moisture content and hardness of the cookies was correlated with addition of microalgae powder. It was observed that hardness measured by sensory analysis increased with the spirulina content. Microalgae had a negative impact on the overall sensory quality.

Investigation of Global Methylation in Peripheral Blood from Breast Cancer Patients

Breast cancer is the most frequent malignancy with high mortality among woman around the world. Global DNA methylation has been investigated by multiple studies and suggested as a screening biomarker for cancer. DNA methylation for two repetitive elements, LINE1 and Alu, was investigated in whole blood DNA from 229 breast cancer patients and 151 controls by using MassARRAY EpiTyper assay. Results showed that the mean methylation level of investigated CpG sites of LINE1 in peripheral blood from breast cancer patients was lower than that in controls (P=8.78E-06), especially for one specific CpG site (LINE1_CpG_1 with P=3.64E-10). ROC curve analysis of LINE1_CpG_1 methylation and LINE1 mean methylation was used to estimate the potential clinical utility of LINE1 methylation, area under the curve (AUC) was 0.73 (95% confidence interval (CI): 0.68-0.79) and 0.68 (95% CI: 0.62-0.74), respectively. In addition, the highest increased risk was observed in the lowest quartile of LINE1_CpG_1 methylation and LINE1 mean methylation (odds ratio (OR)=38.47 and 5.94; 95% CI: 8.77-168.64 and 2.94-11.98; P for trend=1.42E-07 and 1.33E-05 respectively). For Alu, significant hypomethylation of Alu_CpG_13 and Alu_ CpG_14 in peripheral blood of breast cancer cases compared to controls was observed (P=0.002 and P=0.006). For the combined analysis, the AUC of the 10 most important CpG sites of LINE1 and Alu is 0.77 (95% CI: 0.72-0.83). Our study indicates that hypomethylation of specific CpG sites in LINE1 and Alu elements in peripheral blood DNA could be potential biomarkers for breast cancer risk. Further multicenter prospective studies are needed to verify these results.
Correlations and path coefficient analyses of yield and yield related traits in common bean genotypes (Phaseolus vulgaris L.) at Abaya and Yabello, Southern Ethiopia

Common bean is among the major crops grown in southern Ethiopia including Borana zone where the majority of the farmers are Agro-pastoralist and produce the crop mainly for home consumption. However, scarcity of varieties that fit to the environment is one of the major production constraints. Therefore, this experiment was conducted to evaluate 36 common bean genotypes in triple lattice design to generate information on the association of yield and yield related traits, and to determine the direct and indirect effects of yield related traits on grain yield. Thousand seeds weight, seed number per plant, seed number per pod and number of primary branches per plant showed positive and highly significant correlations with grain yield. Moreover, thousand seed weight, seeds per plant and seeds per pods had high positive direct effects on grain yield both at genotypic and phenotypic levels. This suggested the importance of considering these traits during selection to improve grain yield in subsequent generations. In contrast, the negative direct effects of days to flowering and maturity as well as the negative indirect effects of these traits via other traits on grain yield suggested the need to select genotypes for early flowering and maturity for the study area.
Transport and environment in Asian cities: Reshaping the issues and opportunities into a holistic framework

Asian cities have witnessed rapid urbanization and an unprecedented rate of motorization in the last decade. Because of this, negative externalities of urban transport such as congestion and environmental impacts have become serious concerns. A number of past studies in this field have shown that health risks are high in key Asian cities, especially from particulate matters and other pollutants for which urban transport is gradually becoming the dominant source. In this context, this paper presents an overview of the environmental implications of urban transport in Asian cities and what is behind them. It also discusses the emerging policy issues and the commonalties and differences in these cities, including discussions of successes and failures and what have been the underlying reasons. Since mitigation of greenhouse gases has become an international concern in recent years, issues and opportunities for mitigation from the Asian urban transport sector are presented. Finally, this paper discusses ASIF (activity, structure, energy intensity, fuel factors), a holistic transport policy framework for cities, and further proposes a broader framework that adds new dimensions to the ASIF framework. This paper shows that such a framework not only provides guidelines to policymakers on where to start on the transport-environment puzzle but also provides a framework to evaluate the implications of various policies on environment and associated factors.
Relevance of Prosocial Behaviours to Rural Entrepreneurship Development in Nigeria

With the current scourge of unemployment and the poverty condition in Nigeria, rural entrepreneurship has had a cushion effect on the depressing economic condition of the nation. Rural entrepreneurship represents the informal sector of the economy which is characterised by small scale businesses involving petty traders and artisans. Interestingly, most research efforts on business development and effectiveness have focused mainly on businesses within the formal sector with no consideration for those in the informal sector. Although prosocial behaviours have been considered as crucial to the success of any business endeavour, these behaviours were investigated and labelled as Organizational Citizenship Behaviour (OCB) within the formal sector with no reference to rural entrepreneurship. Hence, this paper introduced the concept of Entrepreneurial Prosocial Behaviours (EPB) as those types of behaviours essential for the development of rural entrepreneurship. It examined the nature of rural entrepreneurship in Nigeria, the theoretical explanation of entrepreneurial prosocial behaviours, its dimensions and relevance to the success of rural entrepreneurship in Nigeria. This paper concluded that prosocial behaviours are crucial to the development of small business units and recommended that such be cultivated among rural entrepreneurs. Further, this paper recommended that empirical research be conducted to validate Entrepreneurial Prosocial Behaviours (EPB) as a construct.
Prevalence and Risk Factors of Obesity and Hypertension Among University Students in Rajshahi City, Bangladesh

Obesity has become a new challenge for health care providers in the world, which leads to reduced life expectancy or increased health problems. The aim of the present study was to assess the prevalence and risk factors of obesity and hypertension among the undergraduate and postgraduate students in Rajshahi city. About 675 students were interviewed by standard questionnaires with their verbal consents. In this study, we found that a major portion of the population (13.93% which is about 94 students out of 675) were overweight and 61 students (9.04%) were obese at different stages on the basis of Body Mass Index (BMI) values where 75.41% and 31.15% were male and female students, respectively. About 31.15% of the obese students came from families with monthly income of 31000-40000 taka and 29.50% obese students have at least one obese parent. We also observed that about 32 students (52.46%) out of 61 obese students were pre-hypertensive and 34.43% obese students were stage I hypertensive patient. In this study, we found that the most common risk factors of obesity and hypertension among university students were sedentary life style, physical activity less than 30 min/day, smoking, frequent intake of soft drinks, fast food and food rich in fats (Junk food). This may be the first health survey conducted regarding obesity and hypertension among these university students in Bangladesh, which might be helpful for health workers to raise awareness among the mass people.

The impact of mineral dust on cloud formation during the Saharan dust event in April 2014 over Europe

Abstract. A regional modeling study on the impact of desert dust on cloud formation is presented for a major Saharan dust outbreak over Europe from 2 to 5 April 2014. The dust event coincided with an extensive and dense cirrus cloud layer, suggesting an influence of dust on atmospheric ice nucleation. Using interactive simulation with the regional dust model COSMO-MUSCAT, we investigate cloud and precipitation representation in the model and test the sensitivity of cloud parameters to dust–cloud and dust–radiation interactions of the simulated dust plume. We evaluate model results with ground-based and spaceborne remote sensing measurements of aerosol and cloud properties, as well as the in situ measurements obtained during the ML-CIRRUS aircraft campaign. A run of the model with single-moment bulk microphysics without online dust feedback considerably underestimated cirrus cloud cover over Germany in the comparison with infrared satellite imagery. This was also reflected in simulated upper-tropospheric ice water content (IWC), which accounted for only 20 % of the observed values. The interactive dust simulation with COSMO-MUSCAT, including a two-moment bulk microphysics scheme and dust–cloud as well as dust–radiation feedback, in contrast, led to significant improvements. The modeled cirrus cloud cover and IWC were by at least a factor of 2 higher in the relevant altitudes compared to the noninteractive model run. We attributed these improvements mainly to enhanced deposition freezing in response to the high mineral dust concentrations. This was corroborated further in a significant decrease in ice particle radii towards more realistic values, compared to in situ measurements from the ML-CIRRUS aircraft campaign. By testing different empirical ice nucleation parameterizations, we further demonstrate that remaining uncertainties in the ice-nucleating properties of mineral dust affect the model performance at least as significantly as including the online representation of the mineral dust distribution. Dust–radiation interactions played a secondary role for cirrus cloud formation, but contributed to a more realistic representation of precipitation by suppressing moist convection in southern Germany. In addition, a too-low specific humidity in the 7 to 10 km altitude range in the boundary conditions was identified as one of the main reasons for misrepresentation of cirrus clouds in this model study.

Current Trends in Research on Human Milk Exchange for Infant Feeding

Breastfeeding is critical for the healthy growth and development of infants. A diverse range of infant-feeding methods are used around the world today. Many methods involve feeding infants with expressed human milk obtained through human milk exchange. Human milk exchange includes human milk banking, human milk sharing, and markets in which human milk may be purchased or sold by individuals or commercial entities. In this review, we examine peer-reviewed scholarly literature pertaining to human milk exchange in the social sciences and basic human milk sciences. We also examine current position and policy statements for human milk sharing. Our review highlights areas in need of future research. This review is a valuable resource for healthcare professionals and others who provide evidence-based care to families about infant feeding.
