The role of sublimation as a driver of climate signals in the water isotope content of surface snow: Laboratory and field experimental results

Abstract. Ice core water isotope records from Greenland and Antarctica are a valuable proxy for paleoclimate reconstruction, yet the processes inﬂuencing the climate signal stored in the isotopic composition of the snow are being revisited. Apart from precipitation input, post-depositional processes such as wind-driven redistribution and vapor-snow exchange processes at and below the surface are hypothesized to contribute to the isotope climate signal. Recent ﬁeld studies have shown that surface snow isotopes vary between precipitation events and co-vary with vapor isotopes, which demonstrates that vapor- snow exchange is an important driving mechanism. Here we investigate how vapor-snow exchange and sublimation processes inﬂuence the isotopic composition of the snowpack. Controlled laboratory experiments under dry air ﬂow show an increase of snow isotopic composition of up to 8 ‰ δ18O in the uppermost layer, with an attenuated signal down to 3 cm snow depth over the course of 4–6 days. This enrichment is accompanied by a decrease in the second-order parameter d-excess, indicating kinetic fractionation processes. Using a simple mass-balance and diffusion box model in conjunction with our observed laboratory vapor isotope signals, we are able to reproduce the observed changes in the snow. This conﬁrms that sublimation alone can lead to a strong enrichment of stable water isotopes in surface snow and subsequent enrichment in the layers below. To compare laboratory experiments with realistic polar conditions, we completed four 2–3 day ﬁeld experiments at the East Greenland Ice Core Project site (Northeast Greenland) in summer 2019. High-resolution temporal sampling of both natural and isolated snow was conducted under clear-sky conditions, and demonstrated that the snow isotopic composition changes on hourly timescales. A change of snow isotope content associated with sublimation is currently not implemented in isotope-enabled climate models and is not taken into account when interpreting ice core isotopic records. However, our results demonstrate that post-depositional processes such as sublimation play a role in creating the climate signal recorded in the water isotopes in surface snow. This suggests that the ice core water isotope signal may effectively integrate across multiple parameters, and the ice core climate record should be interpreted as such.
The Effect of Procedural Guidance on Students' Skill Enhancement in a Virtual Chemistry Laboratory.

Various cognitive aids (such as change of color, arrows, etc.) are provided in virtual environments to assist users in task realization. These aids increase users’ performance but lead to reduced learning because there is less cognitive load on the users. In this paper we present a new concept of procedural guidance in which textual information regarding the procedure of a task is provided to users. The users convert this information into physical actions to complete the task, which enhances their learning by creating a consolidated mental model. We use Multimodal Virtual Chemistry Laboratory, where students simulate a chemistry experiment with the help of procedural guidance. Evaluations reveal that the proposed guidance enhances students’ learning and consequently increases their performance in real-world situations.
Increasing Civic Engagement Through Civic Education: A Critical Consciousness Theory Perspective

There is a growing need for increased civic engagement in developing countries. We argue that civic education has not met this need in Nigeria because it is uncritical, but it can be reformed through critical consciousness theory emphasizing knowledge and critical thinking. However, for civic education reforms, we need to understand the relationship between sociodemographic factors and civic engagement. Therefore, we investigated the influence of six sociodemographic factors (gender, location, age, income, education, and ethnicity) on two civic engagement constructs—environmental civility and community volunteering—using the responses of 372 respondents on the Civic Engagement Scale. Results revealed that community volunteerism is mainly influenced by age, gender, and location, while environmental civility is mainly influenced by location and education, and there is a generally low level of civic engagement. The implications of these findings for a critical civic education aimed at increasing critical consciousness and civic action are discussed.
Monitoring of six grape genotypes in response to salt stress in an arid region in Tunisia: morphological parameters

Purpose: This study aimed to valorize the grape genotypes in the oasis of Tozeur, Tunisia, by exploring their salinity tolerance. Research method: The principal genotypes: Arbi, Chetoui, Guelb Sardouk, Kahla, Sfaxi and Muscat d’Italie were subject to two salt treatments: a gradual stress by adding 25 mM NaCl every week until the final doses of 75,100 and 150 mM NaCl and a shock by applying 50 and 100 mM NaCl from the treatment onset. The shoot length and the number of leaves were monitored during salt treatments. Findings: The first mortalities were registered at the 3rd week for Sfaxi under gradual stress conditions, Guelb Sardouk, and Kahla under salt shock. The effects of 75 mM NaCl gradually added were expressed only by the decline of leaves number for the genotypes Chetoui, Kahla, and Sfaxi, while those of low salt shock (50 mM NaCl) were manifested by plant height and leaves number reductions. Salinity damages were aggravated by increasing the salinity. Another response was observed for the studied genotypes: they kept their vegetative apparatus almost unaffected to preserve the photosynthetic capacity. Research limitations: No limitations were founded. Originality/Value: The adverse effects of salinity were more relevant at the end of the stress particularly under the high salt dose (150 mM NaCl). The salinity of irrigation water for our grape genotypes shouldn’t reach 150 mM NaCl. The genotype Arbi was the most tolerant genotype while Kahla was the most sensitive to salinity.

Age-Group Differences in Reactive Strength and Measures of Intra-day Reliability in Female International Footballers

The aim of this present study was to compare the reactive strength index (RSI) characteristics and trial to trial reliability of U17, U19 and Senior female international soccer players. Fifty – seven elite female soccer player participated in the study, (age: 18.1 + 3.1 years; height: 167.5 + 6.3 cm; weight: 61.84 + 7.7 kg). Participants performed 3 maximal repetitions of the 10/5 repeated jump test (10/5RJT) following a specific warm-up and familiarisation protocol. Senior players possessed higher levels of RSI with large effect size present when compared with the U17 (P= 0.043, ES = .97) and U19 (ES = 0.85) age groups. Trivial differences (ES = 0.17) in RSI existed between the U17 and U19 age categories. Trial-to-trial analyses demonstrated 10/5 RJT RSI to possess adequate levels of reliability with a range of mean coefficients of variance (CV) of 3.1 – 7.3 % and intraclass correlation (ICC) between 0.95 – 0.98 present across all three age groups. However, large variations in the between – athlete CV for RSI were revealed ranging from 1 – 27 %, 0.4 – 10.3%, and 1 – 7 % for U17, U19 and senior age groups respectively. These results suggest that age group can distinguish reactive strength capabilities. In addition, female international footballers with higher levels of RSI appear to produce more reliable measures of RSI via the 10/5 RJT.
Effect of Glycine Supplementation of Mandarah Laying Hens Diets on Production Performance and Egg Quality

The current research was conducted to study the effect of dietary supplemental of glycine (gly) levels 0.1 and 0.2 % on modulating productive performance in Mandarah (M) during laying period from 28 to 40 weeks (wks.) of age. The 1st treatment (T1) was fed the basic diet and served as the control treatment with no additional gly. The 2nd and 3rd treatments were fed the basic diet supplemented with 0.1 and 0.2 % gly/kg diet, respectively. Results indicated that hens fed (T2} and (T3) supplementation significantly improved feed conversion ratio for all intervals except from (28 to 30 wks. of age) compared to control. Egg number, egg weight and egg mass values were significantly increase in M hens fed diets containing T2 or T3 compared to control T1 during the whole period studied. Egg quality {shell (thickness and %), albumen %, yolk (% and index)} were significantly affected due to T2 and T3 supplementation to hens. Significant increases have been recorded in abdominal fat % and triglyceride (TG) values of hens in T2 and T3 compared to T1 (control) values at 40 (wks.) of age. Significant decreases have been recorded in litter traits (pH, moisture, nitrogen and ammonia %) of hens of T2 compared to control (T1) values at 40 wks. of age. The results of the current research indicated that gly supplementation during the laying period promoted the productive performance and had beneficial effects on quality of poultry litter.
The integration of corporate social responsibility and marketing concepts as a business strategy: evidence from SEM-based multivariate and Toda-Yamamoto causality models

Research background: This paper integrates the marketing and corporate social responsibility concepts by investigating how the previous studies de-bated CSR as a business strategy. This discussion extended from academics to business practices. Hence, this study investigated the concept of CSR as a business strategy in a multifactorial fashion in the marketing field. Purpose of the article: This study evaluates the modified model of CSR initiatives as business and marketing strategy and their impact on customers' buying behavior. For this purpose, we have taken dimensions of Carroll's pyramid of CSR as marketing strategies. We have also examined the influence of brand loyalty and cause-related marketing as mediating variables and technology as a moderator between dimensions of Carroll's pyramid and customers' buying behavior. Methods: We employed modified theoretical & conceptual model for evaluating the direct and indirect hypothesized relationship. We have collected 693 responses from the structured and adapted questionnaire. The survey was done among marketing and senior managers of the Asian Oeconomia Copernicana, 12(1), 125–157 126 pharmaceutical industry. We employed SEM-based multivariate modeling to examine the hypothesized relationship. Findings & value added: The finding of this research exhibited that dimensions of Carroll’s pyramid of CSR have a positive and significant impact on customers' buying behavior. The results further demonstrated that brand loyal-ty and cause-related marketing positively and significantly impact mediators between CSR dimensions and customers’ buying behavior. Finally, the technology has a significant influence as a moderator between exogenous and endogenous factors. The undertaken study demonstrated important theoretical and practical implications. The modified conceptual framework has provided several new dimensions for future researchers to use and replicate in different economic sectors. On the other hand, practitioners of the pharmaceutical industry should incorporate Carroll's CSR pyramid as business strategies to gain the trust and respect of their customers.

Autoimmune thyroiditis and multiple nutritional factors

Autoimmune thyroiditis (AT) is considered to be the most common autoimmune disease. It is currently accepted that genetic susceptibility, environmental factors, and immune disorders contribute to its development. With regard to nutritional factors, evidence implicates high iodine intake and deficiencies of selenium and iron with a potential relevance of vitamin D status. To elucidate the role of nutritional factors in the risk, pathogenesis, and treatment of AT, PubMed and the Cochrane Library were searched for publications on iodine, iron, selenium, and vitamin D and risk/treatment of AT. Chronic exposure to excess iodine intake induces autoimmune thyroiditis, partly because highly iodinated thyroglobulin (Tg) is more immunogenic. Selenoproteins are essential to thyroid action. There is evidence from observational studies and randomized controlled trials that selenium/selenoproteins can reduce thyroid peroxidase (TPO)-antibody titers, hypothyroidism, and postpartum thyroiditis. AT patients are frequently iron deficient, since autoimmune gastritis, which impairs iron absorption, is a common co-morbidity. In recent years, evidence has emerged pointing to various roles for vitamin D, including, proliferation and differentiation of normal and cancer cells, cardiovascular function, and immunomodulation. Vitamin D deficiency has been especially demonstrated in AT patients. Lower vitamin D status has been found in AT patients than in controls, and inverse relationships of serum vitamin D with TPO/Tg antibodies have been reported. Adequate selenium intake is vital in areas of iodine deficiency/excess, and in regions of low selenium intake a supplement of 50–100 μg/day of selenium may be appropriate. Myo-inositol and selenium are able to restore the euthyroid state as well as improve the wellbeing of AT with subclinical hypothyroidism. Bearing in mind also the safety of these two molecules’ usage, accentuated by the absence of side effects, the Myo-Ins-Se combination can be considered a very efficacious and safe therapy for AT treatment.
Artisanal buffalo milk curd from Charfassion upazila of Bholadistrict in Bangladesh as a potent source of bifidobacteria

The present study explored the traditionally prepared fermented buffalo milk curd to isolate and characterize Bifidobacterium sp. towards developing future probiotics. Standard methods have been applied to identify Bifidobacterium sp. using bifidobacteria selective media, bifidobacteria specific mupirocin resistance test, phosphoketolase activity and commercial biochemical kit. The strains further confirmed by xfp gene PCR amplification. The growth dynamics of the identified isolates was also determined by monitoring the turbidity of the cultured media spectrophotometrically. A total of 20 isolates obtained from selective media were found gram positive, catalase negative, rod or v-shaped, non-motile and identified as presumptive bifidobacteria. All the isolates were resistant (zone diameter <10 mm) to the antibiotic mupirocin. However, the phosphoketolase activity of the isolates were varied significantly (p<0.05). A high, moderate and weak/no phosphoketolase activity was exhibited by 35%, 20% and 45% isolates, respectively. In the contrary, fourteen isolates (70%) amplified well with phosphoketolase activity encoded xfp gene and produced a PCR product of 704 bp. Combining the findings of these three tests, only six isolates (30%) displayed mupirocin resistance, high phosphoketolase activity and amplification with xfp gene. Of these six isolates biochemical test confirmed three isolates as Bifidobacterium mongoliense and two as Bifidobacterium pseudolongum subsp. globosum. The exponential phase growth rate of the six isolates also varied significantly (p<0.05) and ranged from 0.16±0.01/h to 0.34±0.02/h. Traditionally prepared buffalo milk curd from Charfassion upazila of Bhola district, Bangladesh could be a potent source of Bifidobacterium sp. However, species-specific identification and elucidation of probiotic potential are pivotal for future industrial use.

Molecular and Morphological Variations Induced by Gamma Rays in Yardlong Bean

Yardlong bean (Vigna unguiculata (L.) Walp. sub. sp. sesquipedalis) is a climber annual Vigna crop of Leguminosae family with chromosome number 2n = 2x = 22. It’s known as long-podded cowpea, asparagus bean, pea bean, snake bean, garter bean and Chinese long bean. It has ability to fix atmospheric nitrogen with its symbiotic bacteria (Rhizobia) and increases productivity of the soil (Pandey et al., 1989). It is much more a climbing and trailing plant than the cowpea, often reaching 9-12 feet in height and it is characterized by its very long pods 30-90 cm in length with seeds usually 8–12 mm long. It is commonly cultivated T study was carried out to identify the genetic variations in yardlong bean plants irradiated by various doses (75, 150, 300, 450 and 600Gy) of gamma rays using RAPD and ISSR markers techniques as well as, their effect on some vegetative traits were studied. ten RAPD and 10 ISSR markers were used in this investigation. The obtained results showed that the ten RAPD primers produced 117 bands only 94 of them were polymorphic while 23 bands were monomorphic. The percentages of polymorphism among primers ranged from 0.0% to 100%. All of the RAPD primers produced unique bands except OPK-06 primer which did not produced any unique bands. Meanwhile, 62 amplified bands including 26 polymorphic and 36 monomorphic bands were generated by ten ISSR primers. All of the ISSR primers did not produce any unique bands except ISSR4 primer which produced only one unique band, these results demonstrated that this unique sequence could be used as a molecular marker associated with gamma irradiation. The field results showed that the emergence percentage decreased with increasing doses up to 600Gy treatment which gave the lowest emergence percentage. Inconstant values of vegetative characteristics were obtained after each treatment with gamma ray doses; 300Gy treatment gave the highest value of plant height, number of branches, pod length and number of seeds per pod compared to control and other treatments. The values of coefficients of phenotypic and genotypic variation, heritability and expect genetic advance did not follow regular increase or decrease with the radiation doses in both seasons. The present data demonstrate that using gamma rays to induce DNA polymorphism in this plant genome which might be lead to appearance of a desired phenotype and genetic characteristics which could be used in yardlong bean improvement programs.
