Stability of the Trolox Equivalent Antioxidant Capacity (TEAC) of Human Milk Frozen at –20°C for 6 Months

The practice of storing human breast milk (HM) for later use has substantially increased over the last few decades because it allows lactating mothers to continue breastfeeding despite lifestyle changes. Several studies have focused on the safety and nutritional value of milk during the period from the time of storage to that of consumption. To date, few studies have investigated the effect of the storage duration on the antioxidant capacities of stored HM. This study aimed to evaluate the impact of different storage times on the Trolox equivalent antioxidant capacity (TEAC) of frozen HM (−20°C). HM samples from 186 healthy women were collected from women who had term deliveries and a lactating duration between 1 and 24 months. The TEAC values of the frozen HM stored for 1, 2, 4, and 6 months were determined using a working 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) solution. The mean TEAC level of an HM sample, which was frozen and stored at −20 °C for 1 month (1.86 ± 0.82 mM), was compared to those of samples stored for different lengths of time. No significant difference in the mean TEAC values was observed after frozen storage for 2 months (1.88 ± 0.86 mM), 4 months (1.96 ± 0.93 mM), and 6 months (1.91 ± 1.01 mM) (p > 0.05). These results suggest that in cases in which HM needs to be stored for more than 1 month, the storage of frozen HM at −20 °C appears to be the optimal condition for preserving the antioxidant capacity of HM for up to 6 months.
Proton irradiation parameters and chemical separation procedure for the bulk production of high-specific-activity 186gRe using WO3 targets

Abstract Rhenium-186g (T1/2= 89.2 h) is a β− emitter suitable for therapeutic applications. Current production methods rely on reactor production via 185Re(n,γ) which results in low specific activities, thereby limiting its use. Production by p,d activation of enriched 186W results in a 186gRe product with a higher specific activity, allowing it to be used for targeted therapy with limited receptors. A test target consisting of pressed, sintered natWO3 was proton irradiated at Los Alamos (LANL-IPF) to evaluate product yield and impurities, irradiation parameters and wet chemical Re recovery for proof-of-concept for bulk production of 186gRe. We demonstrated isolation of 186gRe in 97% yield from irradiated natWO3 targets within 12 h of end of bombardment (EOB) via an alkaline dissolution followed by anion exchange. The recovery process has potential for automation, and WO3 can be easily recycled for recurrent irradiations. A 186gRe batch yield of 42.7 ± 2.2 μCi/μAh or 439 ± 23 MBq/C was obtained after 24 h in an 18.5 μA proton beam. The target entrance energy was determined to be 15.6 MeV. The specific activity of 186gRe at EOB was measured to be 1.9 kCi (70.3 TBq) mmol−1, which agrees well with the result of a previous 185,186mRe co-production EMPIRE and TALYS modeling study assuming similar conditions. Utilizing enriched 186WO3, we anticipate that a proton beam of 250 μA for 24 h will provide batch yields of 256 mCi (9.5 GBq) of 186gRe at EOB with specific activities even higher than 1.9 kCi (70.3 TBq) mmol−1, suitable for therapy applications.
The Dosimetric Evaluation of An In-House Software Developed For Metal Artefact Reduction On Two Different Radiotherapy Treatment Planning Systems

Metal Artefact Reduction (MAR) is very important in terms of dose calculation in radiotherapy. It was aimed to develop an in-house MAR software as an alternative to commercial software programs and to examine its effectiveness by comparing it with the SMART-MAR software which was available commercially. A phantom containing metal with high atomic number was designed and computed tomography (CT) images of this phantom were taken (Without-MAR images). The obtained CT images were processed with the SMART-MAR software and the developed In-House MAR software. Processed images were compared in terms of Hounsfield unit (HU), absolute dose values ​​in the Accuray and CMS XiO treatment planning systems, and gamma evaluation. The best HU improvement was observed in the developed In-House MAR. The maximum mean percentage differences in absorbed doses at the determined points in Accuray was found 33.3% and 32.5% between Without MAR - SMART MAR and Without MAR- In-House MAR, respectively. The In-House MAR software developed by using MATLAB was shown similar results with the SMART MAR software. Although in-house MAR software needs to be investigated clinically, it is more advantageous than commercially available software in terms of being cost-free, applicability in a shorter time and without reconstruction.
Revisited – possible remains of the 1202 earthquake in Galilee: the Frankish village of Castellum Regis/Miʿilyā

The archaeological remains in two Frankish period sites in Western Galilee prove that the 1202 earthquake, which was extensively mentioned in contemporary texts, had significant impact in Galilee. The earthquake was not specifically mentioned as affecting Western Galilee, but the archaeological remains show that it was severe–violent with high intensity, probably VIII+. The damage seems likely to have been great enough to affect the socio-economic situation of the inhabitants, which contributed to the sale of many properties to the Teutonic Order during the 1220s. The shock in Galilee seems likely to have been in a north–south axis
Copolyethersulfones of 1,4:3,6-dianhydrohexitols and bisphenol A

Abstract The synthesis of biosourced copolyethersulfones by polycondensation of 1,4:3,6-dianhydrohexitol monomers and bisphenol A is reported. Structures and properties of these copolymers were investigated in each case. In the first part, the impact of the position of the two hydroxyl groups of isosorbide, isomannide, and isoidide is discussed. In the second part, we focused on improving the cost/thermal properties balance by introducing controlled proportions of bisphenol A as comonomer. The addition of bisphenol A serves two purposes. The first one is to maintain good thermal and mechanical properties of resulting copolymers. The second reason is to insure low-cost route to copolyethersulfones for a potential use in industrial applications. All the products have been fully characterized by NMR spectroscopy, MALDI-TOF spectrometry, and viscosimetry. The thermal properties were studied by differential scanning calorimetry (DSC).
Media Studies, Audiovisual Media Communications, and Generations: The Case of Budding Journalists in Radio Courses in Greece

In this article, the quality of media studies education through effective teaching utilizing audiovisual media technologies and audiovisual content (audiovisual media communications) to budding journalists as adult learners (18 years and older) is researched, with results primarily intended for application in radio lessons at all educational levels and disciplines (including adult education). Nowadays, audiovisual media communications play an important role in the modern and visual-centric way of our life, while they require all of us to possess multiple-multimodal skills to have a successful professional practice and career, and especially those who study media studies, such as tomorrow’s new journalists. Data were collected after three interactive teachings with emphasis on educational effectiveness in technology-enhanced learning, through a specially designed written questionnaire with a qualitative and quantitative form (evaluation form), as case study experiments that applied qualitative action research with quasi-experiments. The results (a) confirmed (i) the theory of audiovisual media in education, as well as (ii) the genealogical characteristics and habits of budding journalists as highlighted in basic generational theory, something which appears to be in agreement with findings of previous studies and research; and (b) showed that (i) teaching methodology and educational techniques aimed primarily at adult learners in adult education kept the interest and attention of the budding journalists through the use of such specific educational communication tools as audiovisual media technologies, as well as (ii) sound/audio media, as audiovisual content may hold a significant part in a lecture.
Innovative Inorganic Binder Systems for the Production of Cores for Non-Ferrous Metal Alloys Reflecting the Product Quality Requirements

The aim of this study is the evaluation of the parameters of core mixtures using different binder systems with regard to the collapsibility of cores after casting and the resulting product quality of castings reflecting surface requirements based on non-ferrous alloys. The research compares organically bonded core mixtures based on phenol-formaldehyde resins for the production of cores with the shell molding (resin coated sand), currently used in the production of aluminum alloy castings in the Brembo Czech s.r. o. , and mixtures using innovative inorganic binder systems based on geopolymers; GEOPOL® W. The aim of the research is to compare the advantages and disadvantages of these binder systems in order to evaluate the potential of inorganically bonded mixtures to replace organically bonded mixtures, which would lead to a significant reduction in the environmental impacts of industrial production of castings.
The Effect of Inquiry-Based Learning on Academic Success: A Meta-Analysis Study

Inquiry Based Learning (IBL) is a student-centered strategy within the constructivist learning approach. This strategy is an important approach that makes students active inside and outside the classroom, and enables students to work in groups, conduct research, present their research, and increase their academic success. When the literature is reviewed, there are many studies that show that IBL increases the academic success of students. The aim of this study is to make the meta-analysis of articles and theses carried out in Turkey between the dates of 01.01. 2000 and 01.03. 2020 that investigate the impact of IBL on the academic achievement. In this study, meta-analysis method was used to determine the effects of IBL on students’ academic achievement based on grade levels and publication types. The studies evaluated within the scope of this study were created by using the databases of Google Scholar and the National Thesis Center of the Council of Higher Education. To this end, 30 studies were selected in accordance with year, method, data, and publication type criteria. In this study, the thesis and article evaluation form developed by the researchers was used as the main means of data collection. Comprehensive Meta-Analysis (CMA) program was used to analyze the data. According to the results of this study, it is concluded that IBL significantly increases the academic achievement and the effect sizes are meaningful when grade levels are compared. That is, IBL at high school level is more effective than other educational levels, and when the effect sizes are examined, there are no significant differences based on the types of publication (i.e., articles and theses).
Effects of timber harvest on survival and movement of stream salamanders in a managed forest landscape

With escalating anthropogenic alteration of landscapes worldwide, managed forests are increasingly important as providers of ecosystem services and wildlife habitat. Therefore, it is crucial to maintain a balance between producing forest products and biodiversity conservation. Several studies have reported negative effects of forest management on terrestrial plethodontid salamanders, but fewer have focused on stream-dwelling species or evaluated mechanisms for shifts in their abundance (e.g., mortality vs. movement). We used a before – after – control – impact design to examine the effects of clear-cut harvesting on a semi-aquatic stream-breeding salamander endemic to the Ouachita Mountains, Desmognathus brimleyorum . We conducted a three-year capture – mark – recapture (CMR) study at three streams within a managed pine ( Pinus spp.) landscape in west-central Arkansas, USA. Loblolly pine ( Pinus taeda ) stands surrounding two of the streams were clear-cut (leaving a 14 – 21 m wide forested buffer on each side of the stream) midway through the study; the third stream served as a control site and remained unharvested. We estimated apparent survival using open CMR models and compared salamander movement over time and between harvested and control streams. Overall, our models revealed seasonal and temporal variation in salamander survival and abundance, but little evidence for strong immediate effects of timber harvesting on post-metamorphic salamanders within two years postharvest. However, there was increased salamander movement at sites where forest harvest occurred. Our results suggest that streamside buffers of at least 14 – 28 m on either side of a stream are effective for minimizing immediate effects of forestry activities on juvenile and adult stream-dwelling salamanders, when timber harvest occurs in the winter months. These results will inform management decisions aimed at conserving biodiversity and ecosystem integrity in managed forest landscapes while also ﬁ lling a critical gap in the knowledge of stream salamander demographic parameters.
Testing the expectations hypothesis and explaining the determinants of term premia: evidence from the Indian money market

ABSTRACT The pure expectations hypothesis states that the current yields on bonds with different maturities reflect investor expectations of future interest rates. Analysing the short-term inter-bank rates in a Vector Error Correction Model (VECM), the study could reject the pure as well as the general expectations theory in case of the 1 month and 3 months rates but not in case of 14 day rates. The term premia is found to be time-varying. The study attempts to quantify and decompose the term premia, inherent in the money market rates. The study uses the market spreads derived from the swap market, T-Bills, and CD markets to understand the level of decomposition of the term premia. A latent factor model was used to break down the term premia and decompose the same into credit and liquidity risk factors by using information from related money market instruments.
Silicon-controlled Rectifier-based Electrostatic Discharge Protection Circuit with Additional NPN Parasitic Bipolar Junction Transistor for 5-V Application

This paper proposes a novel protection circuit based on a silicon-controlled rectifier (SCR) to prevent electrostatic discharge (ESD) at low voltages. The proposed device consists of an additional NPN parasitic bipolar transistor operated via application of an N+ diffusion region and a well breakdown voltage, to reduce the high trigger voltage caused by the well breakdown voltage of the existing SCR structure. Furthermore, the proposed device exhibits an improved trigger voltage, holding voltage, and dynamic resistance component when compared with existing parasitic PNP bipolar transistors. The proposed ESD protection circuit was manufactured using a 0.18 μm bipolar-CMOS-DMOS; it exhibited a significant improvement in electrical characteristics such as trigger voltage (8.1 V) and holding voltage (3.55 V), according to the results of transmission line pulse measurement. Hence, it is deemed to be suitable for 5-V-class applications.
Surface area and layer charge of smectite from CEC and EGME/H2O-retention measurements

The total specific surface area (TSSA) and smectitic layer charge (Qs) calculated from the structural formulae and unit-cell dimensions of 12 pure smectite samples were used as a reference in the design and evaluation of TSSA and Qs measurement techniques based on cation exchange capacity (CEC), H2O retention at 47% RH, and ethylene glycol monoethyl ether (EGME) retention. A thermogravimetric analysis-mass spectrometry (TGA-MS) technique was used to study the release of H2O from smectite on heating, and to introduce a correction for H2O remaining in the smectite after heating to 110°C, because the sample weight at this temperature has been used routinely as a reference in CEC and EGME sorption measurements. A temperature of 200°C was found to be the optimum reference for such measurements.A good agreement between Qs from the structural formula and from CEC was obtained when this correction was applied. The TSSA of smectite was measured with similar accuracy (mean error of ±5–7%) by three techniques: (1) using mean H2O coverage; (2) using mean EGME coverage; and (3) using a combination of H2O coverage and CEC. A reduction of the mean error from 5–7% to 4% can be obtained by averaging these measurements, and a further reduction to 3% by introducing corrections for the dependence of H2O and EGME coverage on layer charge. The study demonstrates that Ca2+-smectite samples at 47% RH have H2O contents corresponding to 88–107% of the theoretical mass of a monolayer and offers an explanation of this variation.
Financial Performance and Gender Diversity: The Moderating and Mediating Effect of CSR Disclosure and Expenditure of Listed Firms in India

The study examines the moderating and mediating effect of corporate social responsibility (CSR) disclosure and CSR expenditure on the association between listed firms’ financial performance and gender diversity. There are 80 listed firms with 800 firm-year observations from 2010 to 2019 that qualified for the study using the Indian stock market. The first finding shows a negative association between financial leverage and gender diversity. The second finding shows that the implementation of CSR disclosure hurts the improvement of gender diversity. The third finding shows that CSR expenditure improves gender diversity of listed firms in an emerging market. The fouth finding shows that CSR expenditure positively mediates the negative association between financial leverage and gender diversity. The fifth finding shows that CSR disclosure does not mediate the association between financial performance (return on assets, price to book ratio and financial leverage). The sixth finding shows that CSR expenditure negatively moderates the negative association between return on assets and gender diversity.
Dietary conjugated linoleic acid supplementation alleviates high lipid-induced intestinal damage in grass carp (Ctenopharyngodon idella)

High lipid diet has been shown to increase the intestinal permeability and inflammatory properties in mammals, and the conjugated linoleic acid (CLA) could alleviate the symptoms caused by high lipid diet. However, the information about the impact of high lipid diet on the intestine of fish was limited, and the effect of CLA on intestinal changes induced by high lipid diet in fish is still unknown. Therefore, an 8-week feeding trial was conducted to investigate CLA's potential effects against high lipid diet-induced intestinal physical and immune barrier damage in grass carp (Ctenopharyngodon idella). Three isonitrogenous diets, including fish meal-control diet, control diet supplemented with 3.5% soybean oil as high lipid diet (HL), and HL replaced with a 2.5% CLA diet (CLA) formulated. Compared to the control group, HL significantly increased the expression of pro-inflammation genes (TNF-α, IL-8, IL-1β, NF-κB p65, IκBα, IKKα, IKKβ, and IKKγ) and down-regulated the gene expression of anti-inflammation cytokine (IL-10). The expression of intestinal tight junction proteins (ZO-1, occludin, claudin c, and claudin b) in fish fed with high lipid diets was lower than those fed with control diets. In the CLA group, the gene expression of pro-inflammation cytokines was decreased, and the expression level of the anti-inflammation cytokine was increased, compared with those in HL group. Moreover, feeding with high lipid diets induced fish intestine and dietary CLA damage could alleviate the symptom as shown by HE staining. In conclusion, this research revealed that CLA could mitigate high lipid diet-induced inflammation and permeability in the intestine of grass carp.
Assessment of the Education Environment of the Saudi Board of Family medicine, KSA. 2020

Background: Competent educational environment for medical postgraduate is crucial to ensure sound clinical outcome. The quality of the educational environment is influenced by many factors, physical, social and intellectual. The current study aimed at assessing the educational environment in a postgraduate Saudi Board for Family Medicine in Jeddah. Methodology: Through cross sectional study design, all residents in the Saudi Board of Family medicine in Jeddah were invited to participate in the study; they were asked to fill a predesigned adopted valid questionnaire based on the Scan of Postgraduate Educational Environment Domain (SPEED) which is used to assess the quality of the Post Graduate Medical Education. Data were collected during gathering of the residents in a usual didactic teaching day. A total of 186 residents responded, making a response rate 93%. Results: Out of all participants (n=186), females formed two thirds of the residents (60.8%), their mean age was 27.6±2.27 years, with an almost equal representation of the four residency levels. The highest scores about the quality of the educational process was observed in the item regarding the supervisors being respectful towards the registrars (mean score 4.1 out of 5), followed by the being approachable and helpful (mean score 4.0). The lowest scores were observed regarding presence of staff in general who have positive impact on the educational environment (mean score 3.2), followed by availability of good clinical supervisors all the time (mean score 3.3). The overall mean score accounted for 3.6± 0.56, although it was higher in females (3.7±0.642) than males (3.5±0.661), and in those in R1 (3.7±0.509) and R4 (3.7±0.605), however, these differences are not statistically significant p>0.05. Also, no statistically significant correlation between and age and overall mean score was observed. Conclusion and recommendations: The Saudi Board residents for Family Medicine considered their educational environment as more positive than negative with potential areas for improvement. Although females perceived the educational environment better than male trainees, no significant changes observed along the different stages of the program. It is recommended to use these findings in reforming the educational environment in the Saudi Board.
