Effect of different salt concentration on the physical properties of frozen thawed egg yolk

Freezing can enhance the storage time of liquid egg products, but egg yolk undergoes an irreversible textural and structural change when it is cooled to – 6 8 C. In this study, the effects of different salt concentrations on the physical properties of frozen-thawed egg yolk were investigated. The pasteurised liquid egg yolk (LEY) was treated with 4, 5, and 6% of NaCl before freezing and it was stored at – 18 8 C for 4 weeks. The colour, pH, and rheological characteristics (firmness, consistency, cohesiveness, and index of viscosity) of yolk samples were evaluated before and after freezing. Salt treatment resulted in preventing gelation, with decreasing firmness, consistency and viscosity compared to control samples. The pH of all yolk samples increased during frozen storage. The lightness value decreased in treated samples and increased in the control sample after freezing. The results indicated that the applied salt concentrations could inhibit protein aggregation of LEY induced by freezing during the storage period. At least 5% salt concentration could reduce effectively the changes in rheological properties.
Understanding the Intrinsic Surface Reactivity of Single-Layer and Multilayer PdO(101) on Pd(100)

We investigated the intrinsic reactivity of CO on single-layer and multilayer PdO(101) grown on Pd(100) using temperature-programmed reaction spectroscopy (TPRS) and reflection absorption infrared spectroscopy (RAIRS) experiments, as well as density functional theory (DFT) calculations. We find that CO binds more strongly on multilayer than single-layer PdO(101) (∼119 kJ/mol vs 43 kJ/mol), and that CO oxidizes negligibly on single-layer PdO(101), whereas nearly 90% of a saturated layer of CO oxidizes on multilayer PdO(101) during TPRS experiments. RAIRS further shows that CO molecules adsorb on both bridge-Pdcus and atop-Pdcus sites (coordinatively unsaturated Pd sites) of single-layer PdO(101)/Pd(100), while CO binds exclusively on atop-Pdcus sites of multilayer PdO(101). The DFT calculations reproduce the much stronger binding of CO on multilayer PdO(101), as well as the observed binding site preferences, and reveal that the stronger binding is entirely responsible for the higher CO oxidation activity o.
The Relationship Between Perceived Social Support and the Psychological Well-Being of Pregnant Women Expecting Their First Child (Primigravida)

Psychological well-being is a very important factor in maintaining positive emotions. One way to maintain psychological well-being is through positive perception of social support, which can come from family, friends, and significant others. The purpose of this study is to determine the relationship between perceived social support and the psychological well-being of pregnant women expecting their first child ( primigravida ). This research uses quantitative method with measuring instrument in the form of a psychological scale consisting of two parts. This study involved 154 respondents, who were pregnant women expecting their first child. The results show that there was a positive relationship between perceived social support and the psychological well-being of pregnant women expecting their first child, with a value of r = . 423 and a value of p = . 000. The conclusion of this study is that the higher the perceived social support, the higher the psychological well-being of pregnant women expecting their first child. Conversely, the lower the perceived social support, the lower the psychological well-being of pregnant women expecting their first child.
Formation of ultra-low resistance contact with nickel stanogermanide/heavily doped n+-Ge1−xSnx structure

We examined the formation of Ni(Ge1−xSnx)/n+-Ge1−xSnx contacts with Sb- and P-doped Ge1−xSnx epitaxial layers with various electron concentrations and investigated the crystalline structure and contact resistivity. The fully maintained strain and no serious degradation of the crystallinity were confirmed in the Sb-doped Ge1−xSnx layer after Ni stanogermanidation, while the Sn content slightly decreased. The contact resistivity of Ni(Ge1−xSnx)/Sb-doped Ge1−xSnx interface achieved a value lower than the P-doped samples, in spite of high Sn contents with a Ni germanidation temperature of 350 °C. The ultra-low contact resistivity as low as 10−9 Ω cm2 was obtained with the Ni(Ge1−xSnx)/Sb-doped Ge0.935Sn0. 065 sample with an electron concentration of 1.8 × 1020 cm−3.

Predictive Relationships Between Incivility Behaviors Faced by Guidance Counselors and Subjective Well-Being and Life-Domain Satisfaction

In this study, it was aimed to determine the predictive relationships between the incivility behaviors faced by guidance counselors and subjective well-being (SWB) and life-domain satisfaction. The design of the study was based on the relational survey model. The study group was selected using the disproportionate appropriate sampling method. A total of 350 (198 females and 152 males) guidance counselors, who were in charge in schools and the Guidance and Research Center, were recruited for this study. The "School Incivility Scale-SIS" developed by Yildirim, Unal and Surucu (2013) to measure the rude behaviors faced by guidance counselors, and the "Subjective Well-Being Scale" developed by Tuzgol Dost (2005a) to determine the subjective well-being level, and "Personal Wellbeing Index-A" adapted into Turkish by Şimsek (2011) to determine satisfaction in life-domains were used to collect data. The results revealed that the most significant variable affecting the SWBs of guidance counselors was incivility, and there was a negative linear relationship between SWB and incivility. It was determined that the most important variable affecting life-domain satisfaction was SWB, and there was a positive linear relationship between life-domain satisfaction and SWB. It was determined that the second most important variable affecting life-domain satisfaction is incivility, and there is a negative linear relationship between life-domain satisfaction and incivility.
A Unified MIMO Optimization Framework Relying on the KKT Conditions

A popular technique of designing multiple-input multiple-output (MIMO) communication systems relies on optimizing the positive semidefinite covariance matrix at the source. In this paper, a unified MIMO optimization framework based on the Karush-Kuhn-Tucker (KKT) conditions is proposed. In this framework, with the aid of matrix optimization theory, <xref rid="theorem1" ref-type="theorem">Theorem 1</xref> presents a generic optimal transmit covariance matrix for MIMO systems with diverse objective functions subject to various power constraints and different levels of channel state information (CSI). Specifically, <xref rid="theorem1" ref-type="theorem">Theorem 1</xref> fundamentally reveals that for a diverse family of MIMO systems, the optimal transmit covariance matrices associated with different objective functions under various power constraints can be derived in a unified generic water-filling-like form. When applying <xref rid="theorem1" ref-type="theorem">Theorem 1</xref> to the case of multiple general power constraints, we firstly equivalently transform multiple power constraints into a single counterpart by introducing multiple weighting factors based on Pareto optimization theory. The optimal weighting factors can be found by the proposed modified subgradient method. On the other hand, for the imperfect MIMO system with statistical CSI errors, we firstly address the non-convexity of the robust optimization problem by following the idea of alternating optimization. Finally, our numerical results verify the optimal solution structure in <xref rid="theorem1" ref-type="theorem">Theorem 1</xref> and the global optimality of the proposed modified subgradient method, as well as demonstrate the performance advantages of the proposed alternating optimization algorithm.
Community Knowledge and Perception on Climate Change and Drinking Water Supply in Nzoia River Basin, Kenya

Nzoia River Basin is one of the regions in Kenya that is highly vulnerable to climate change. An understanding of community knowledge and perception on climate change and drinking water supply will provide strategic directions for national and county government policy, adaptation strategies and development of community-based guidelines on climate change. This study assessed community knowledge and perception on climate change and drinking water supply in Nzoia River Basin. A cross-sectional survey design was used. Three counties were randomly selected from the basin for study with Busia representing the lower catchment, Kakamega middle catchment and Trans Nzoia upper catchment. The study was carried out from May, 2017 to September, 2017. Multistage random sampling technique was used to select the 403 households administered with questionnaires. An observation checklist was used by the interviewers to collect household- and community-related information. The study results revealed that the community largely comes from low socio-economic background: only 24 % had post secondary education or higher, the majority were small scale farmers, housewives, casual workers and househelps (58 %), and only 25 % earned a monthly income above Ksh. 20,000 (equivalent to US $200). The majority of the participants 81 % had some knowledge about climate change but 19 % did not. On level of knowledge about climate change, 70% know a little/something about climate change, 21% know nothing about climate change and 9% know a lot about climate change. Majority of respondents, 76% receive climate change news from mass media (radio, newspaper and magazines, television); and 81 % point out that climate change will have public health risks in the community. The knowledge level about climate change in the basin was average. National and county governments should work with the sector stakeholders in the basin to improve community knowledge and perception regarding climate change, drinking water supply and health needs with proper content. The results of this study will go a long way in bridging the gap between policy formulation and building adaptive capacity to climate change in the basin.
Effects of Ozone Treatment on the Storage Quality of Post-Harvest Tomato

Abstract Effects of ozone treatment on the storage quality of post-harvest tomato were investigated. The tomatoes packed in microporous film were treated with 4.29 mg·(m3)−1, 8.57 mg·(m3)−1, 12.86 mg·(m3)−1 and 17.14 mg·(m3)−1 ozone gas for 1 h at 0℃. The firmness, ethylene, vitamin C (VC), malonaldehyde (MDA), ascorbate peroxidase (APX), peroxidase (POD) and aromatic compounds were tested to determine the proper ozone concentrations. Compared with other treatments, 17.14 mg·(m3)−1 ozone could maintain the firmness of tomato, depress ethylene, keep the content of VC and aromatic compounds, and inhibit the accumulation of MDA and activity of POD and APX, which had a good fresh-keeping effect on tomato.
TEACHER PERSPECTIVES ON HIGH SCHOOL IN ACEH PROVINCE ABOUT NATURAL DISASTERS

The Indonesian government has made efforts to restore the structure and development of school responses, including increasing knowledge, skills, and disaster management operating systems in schools. School leaders and teachers are expected to balance the need for standard operating procedures with the ability of organizational structures to respond to specific problems caused by disasters. Teacher enhancement is expected to provide a more active role for students and overcome their stress in post-disaster situations. This study aimed to examine the perspective of high school teachers on knowledge of natural disasters and natural disaster mitigation. A descriptive statistical approach is used to describe and explain teacher knowledge and mitigate natural disasters. Explaining how much influence or relationship between teachers' knowledge on disaster mitigation is done. The sample in this study was high school teachers in Aceh province, with 389 teachers. The research data collection used an instrument in the form of a questionnaire. The results showed that the perspective of high school teachers regarding knowledge of natural disasters was in the high category on average; the average teacher knew general knowledge of natural disasters, signs of catastrophe, classification of natural disasters, and causes of natural disasters. Not much different from the results of the teacher's perspective regarding natural disaster mitigation in the very high category, planning in the mitigation process, policies, operational disaster procedures, signs of disaster evacuation have been recognized by SMA teachers in Aceh province. The level of knowledge of high school teachers with mitigation has a significant relationship, so the higher the knowledge of high school teachers about natural disasters, the more high-school teachers can mitigate against natural disasters.Keywords: Teacher's Perspective, Natural Disaster Knowledge, Natural Disaster Mitigation, Regression Analysis
Post-synthetic modification of metal–organic frameworks for chiral gas chromatography

Chiral metal–organic frameworks (MOFs) show great potential in chiral catalysis and separation. However, their application is still hindered by the limited availability of chiral MOFs and chiral recognition centers due to the great challenges for direct synthesis of chiral MOFs with designed chiral recognition sites. Here we report a post-synthesis approach for the facile preparation of chiral MOFs for chiral gas chromatography. Five chiral MOFs with an identical parent framework but different chiral recognition sites were synthesized via grafting various chiral recognition sites of ligands onto MIL-101–NH2. The chiral MOF-coated capillary columns gave good resolution for the separation of diverse racemates with superior separation to the commercial chiral capillary columns. The results reveal that the post-synthesis approach is convenient to fabricate target chiral MOFs with pre-designed functions with the ability to avoid blind synthesis of chiral MOFs via direct synthesis and to facilitate the evolution of chiral stationary phases in chiral chromatography.
Evaluation of Yangon city tap water quality and the efficacy of household treatment

Yangon was one of the first cities in Asia to establish a tap water system. However, the city's water supply infrastructure now lags far behind those of other regions as a consequence of political instability over the last six decades. The installation of disinfection facilities in the tap water system and the enactment of the Myanmar National Drinking Water Quality Standard (MNDWQS) were accomplished only recently during the short period of democratic government. Due to the lack of reliable published information, the suitability of the tap water for drinking remains unclear to city residents. The quality of tap water and bottled water in the central business district was examined to assess compliance with the MNDWQS. The results showed that 95% of tap water delivered to homes was contaminated with Escherichia coli or coliform bacteria. Only 14% of bottled water was free of E. coli and coliform contamination. The efficacy of household treatment devices was tested, and ceramic purifiers (CPs) and reverse osmosis (RO) devices were found to be highly (>99%) effective for E. coli elimination. RO devices performed better in terms of dissolved organic carbon reduction at 60% compared with 43% reduction with CPs.
Effect of Swirl Strength on the Flow and Combustion Characteristics of Pulverized Biomass Flames

ABSTRACT This article reports on the effect of swirl intensity on the flow and combustion characteristics of pulverized olive waste (OW) burning. Numerical simulations are carried out using the computational fluid dynamics (CFD) Commercial Software “Fluent ANSYS14” by choosing appropriate model parameters. The biomass furnace consists of a vertical cylinder equipped with a swirling co-flow injection burner. The particles of pulverized biomass (OW) are injected transversally into the furnace just near the co-flow exit, via four square-shaped injection nozzles. The non-premixed combustion model with mixture fraction/PDF model for turbulence-chemistry interactions is used. Standard k-ε turbulence model closure, discrete phase model (DPM) for tracking the motion of individual particle and P-1 radiation model for flame radiation inside the combustor are used in the numerical simulation. Four different swirl numbers Sn = 0.38, 0.95, 1.2 and 1.42 are used in this study in order to investigate the swirl intensity effect on the flow and combustion behavior. The results showed that the flow and the flame characteristics such as axial velocity, streamlines, gas temperature, flame length and CO2, CO and O2 concentrations are affected by the swirl intensity.
Psychological Effects of COVID-19 on Pregnant Women and New Mothers Living in a US Hotspot

Background: This study investigated COVID-19 related psychological distress among expectant and new mothers, with and without infection, in metropolitan New York. It also examined the trajectories of participants' distress during pregnancy and postpartum, and the moderating effect of socioeconomic status (SES). Methods: An online survey was conducted April through June 2020 among expectant and new mothers with infants (<12 months) (N=642). Associations between infection status and psychological symptoms, suicidal ideation, and substance use were examined. Changes in distress related to COVID-19 infection and SES were then examined. Results: We found elevated anxiety and depression among infected compared to uninfected women. Similarly, infected, compared to uninfected women, had elevated risk for suicidal thoughts (quite often, AOR=3.97, sometimes AOR=13.2), and for substance use [alcohol (AOR=3.30); tobacco (AOR=4.54); cannabis (AOR=7.01); heroin (AOR=7.09); cocaine (AOR=10.05)]. Differences in trajectories of distress across pregnancy between the two groups were significant. Among infected women, distress was consistently high throughout. Among uninfected women, it started low and intensified toward the end of pregnancy. SES further moderated the impact of infection on distress. During earlier trimesters, infected/low SES women had greatest, and uninfected/high SES women had lowest, levels of distress. Their trajectories converged nearing childbirth.Conclusions: New and expectant mothers, especially those infected, have suffered substantial psychological distress due to the pandemic. Moreover, SES moderated the trajectory of distress. Infected women who also had low SES experienced the highest distress levels among all groups. Mitigating strategies are imperative to alleviate this distress.
Atmospheric Compensation of PRISMA Data by Means of a Learning Based Approach

Atmospheric compensation (AC) allows the retrieval of the reflectance from the measured at-sensor radiance and is a fundamental and critical task for the quantitative exploitation of hyperspectral data. Recently, a learning-based (LB) approach, named LBAC, has been proposed for the AC of airborne hyperspectral data in the visible and near-infrared (VNIR) spectral range. LBAC makes use of a parametric regression function whose parameters are learned by a strategy based on synthetic data that accounts for (1) a physics-based model for the radiative transfer, (2) the variability of the surface reflectance spectra, and (3) the effects of random noise and spectral miscalibration errors. In this work we extend LBAC with respect to two different aspects: (1) the platform for data acquisition and (2) the spectral range covered by the sensor. Particularly, we propose the extension of LBAC to spaceborne hyperspectral sensors operating in the VNIR and short-wave infrared (SWIR) portion of the electromagnetic spectrum. We specifically refer to the sensor of the PRISMA (PRecursore IperSpettrale della Missione Applicativa) mission, and the recent Earth Observation mission of the Italian Space Agency that offers a great opportunity to improve the knowledge on the scientific and commercial applications of spaceborne hyperspectral data. In addition, we introduce a curve fitting-based procedure for the estimation of column water vapor content of the atmosphere that directly exploits the reflectance data provided by LBAC. Results obtained on four different PRISMA hyperspectral images are presented and discussed.
Predominance of blaTEM and tetA genes in antibiotic-resistant Escherichia coli isolates from Laguna Lake, Philippines

Lakes are one of the sinks of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs); however, information on ARB and ARGs in lakes in the Philippines is scarce. In this study, Escherichia coli was isolated from the largest freshwater lake in the Philippines, Laguna Lake, to detect antibiotic resistance and the presence of ARGs. Broth microdilution assay (BMA) and molecular identification of five environmentally prevalent ARGs (strA, blaCTX-M, blaSHV, blaTEM, and tetA) were performed. The majority (75.70%) of the isolates harbored at least one of the targeted antibiotic genes. Multiplex PCR detected about 49.07% of the isolates had genes for extended-spectrum β-lactamases (ESBL), which were mostly represented by blaTEM (47.66%). The genes strA and tetA were observed in this study with detection frequencies of 29.91 and 45.33%, respectively. About 95.69% of thermotolerant E. coli isolates were non-susceptible to six different antibiotics using BMA. Nearly 37% of the isolates were found to be multidrug-resistant (MDR) with most isolates resistant to ampicillin (81.72%). Furthermore, the occurrence of ESBL genes was significantly correlated with tetA genes (P = 0.013). To date, this study is the first to report on the presence of MDR and thermotolerant E. coli in Laguna Lake, Philippines.
