PHYTOCHEMICAL AND BIOLOGICAL STUDY OF (Senecio glaucus subsp. coronopifolius ) (MAIRE) C. ALEXANDER GROWING IN EGYPT

Senecio glaucus subsp. coronopifolius (Maire) C. Alexander is wild annual herb distributed in the Egyptian deserts. Total phenolic and flavonoid content of plant root were determined using both HPLC and colorimetric analysis. Syringic acid and hesperidin (1378.802 and 6638.247 mg / 100 gm. dried plant root powder, respectively) were of the highest concentration compounds resulted from HPLC analysis of total phenolic and flavonoid content. The colorimetric estimation of total phenolic and flavonoid content resulted in concentration of (98.23 ± 0.28 mg/gm. expressed as Gallic acid equivalent (GAE) and 35.9± 0.17 mg/gm. expressed as quercetin equivalent (QE), respectively). GC-MS analysis of un-saponifiable matters and fatty acid methyl esters of the plant leaves indicated that octacosane (11.85%) and linolenic acid methyl ester (31.07%) (polyunsaturated fatty acid) were the major identified compounds, respectively. The DNA of the plant was analyzed using twelve random decamer primers. A total of 52 random amplified polymorphic DNA (RAPD) markers were identified. Root extracts (ethyl acetate, acetone and methyl alcohol) were subjected to determine the antimicrobial behavior and also their cytotoxic activity, by using (3(4, 5dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide) (MTT) assay against colon carcinoma cell lines (HCT-116). Among the fore mentioned extracts, root ethyl acetate extract gave appreciable antibacterial and antifungal behavior and also had promising cytotoxic activity with IC50 = 7.39 ±1.2 μg/ml. Root methyl alcohol extract showed antioxidant activity with IC50 = 79.57 ± 0.74 μg/ml, using 2, 2-diphenyl-1picrylhydrazyl (DPPH) assay.
An Examination of Parental College Expectations’ Mediating Role between Children’s Savings Accounts and Children’s Educational Attainment by Income Level

Even though ownership of a Children’s Savings Account (CSA), children’s academic achievement, and parental college expectations are potentially key components for closing the inequality gap in education, the interdependence of these elements is not yet fully understood. Guided by the Theory of Planned Behavior, we utilize structural equation modeling (SEM) in this cross-sectional study to examine the mediating role of parental college expectations on the relationship between ownership of a Harold Alfond College Challenge (HACC) account and parents’ perception of children’s math and reading abilities by the level of household income. Although it is currently a universal, opt-out CSA program available to all babies born in Maine, HACC started in 2008 as an opt-in program, and it is this timeframe that is the focus of the current study. SEM models utilizing survey data from a sample of Maine parents reveal a positive association between the Alfond Grant enrollment and parental college expectations among low-to-moderate income families. Moreover, parental expectations are found to be a complete mediator between having a HACC account and parental perceptions of children’s math ability (but not reading ability) among low-to-moderate income students. No findings were significant for high income families. Correlational evidence from this study suggests that HACC may complement schools’ academic objectives in Maine, particularly about improving parents’ perceptions of their child’s math performance among low-to-moderate income families. This study highlights the need for more rigorous research on HACC and its potential effects on children’s educational attainment.
Effect of pelleted browse-based feed with a basal diet of Andropogon gayanus for sheep on intake, nutrient digestibility and some haematological and blood biochemical parameters.

The study was designed to evaluate the nutritional quality of pelleted diets based on four of the major feed resources fed to small ruminants by farmers in the Accra Plains. Leaves of Samanea saman, Acacia auriculiformis and Ficus exasperata and cassava peels were dried, mixed with other ingredients and pelleted. A preference trial showed sheep accepted all the four supplements with a marked preference for cassava peelsbased (CP-B) and Samanea saman-based (SL-B) supplements compared with Acacia auriculiformis-based (AL-B) and Ficus exasperata-based (FL-B) supplements (P<0.05). The supplements were subsequently fed to Eight West African Dwarf sheep on a basal diet of Andropogon gayanus (Gamba grass) hay in Latin square design. Dry matter intakes (DMI) did not differ by the type of supplement (P>0.05). However, crude protein intake (CPI) was higher (P<0.05) in sheep fed AL-B and FL-B than those fed SL-B and CP-B. Dry matter and neutral detergent fibre (NDF) digestibility were lowest (P<0.05) for sheep fed CP-B. Dietary treatments did not affect haematological parameters, except for neutrophil percentage which was higher (P<0.05) in sheep fed CP-B than those fed SL-B. Animals fed CP-B had the lowest monocyte concentrations (P<0.05). Furthermore, all the serum biochemical parameters were not affected by dietary treatment except total protein concentration which was highest (P<0.05) in sheep fed on AL-B. It is concluded that the feed resources available to the small ruminant keepers can be used to prepare pelleted supplements that are acceptable to sheep and help sustain appreciable performance on low quality forages during the dry season without any deleterious effects on intake, digestibility, physiology and health.

زمینه مطالعاتی: یونجه یکی از مهمترین گیاهان علوفه­ای است که در تغذیه دام به شکل علوفه خشک در ایران استفاده می­شود. با این حال، مقدار قابل توجهی از مواد مغذی یونجه به دلیل تیمارهای مکانیکی در طی فرآیند خشک کردن و ذخیره­سازی از بین می­روند. تولید سیلوی یونجه در سال­های اخیر مورد توجه بیشتر دامداران قرار گرفته است. یونجه یکی از علوفه­هایی است که به دلیل داشتن سطح بالای پروتئین، ظرفیت بافری بالا و کربوهیدرات محلول در آب پایین سیلو کردن آن مشکل می­باشد و افزودنی­های سیلو در زمان سیلو کردن باید مورد استفاده قرار گیرد. از مواد افزودنی با خاصیت محافظتی (برپایه اسیدهای آلی) برای جلوگیری از رشد قارچ و مخمر در سیلاژ و افزایش پایداری هوازی استفاده شده است. اخیرا استفاده از گیاهان معطر و محصولات آنها به دلیل اثرات ضد قارچ، ضد باکتری و آنتی­اکسیدان آنها افزایش یافته است. هدف: این آزمایش به منظور بررسی اثرات اسانس­هسته­لیموترش بر خصوصیات شیمیایی و پایداری­هوازی سیلاژ یونجه انجام شد. روش کار: یونجه در مرحله گلدهی برداشت شد و با یک چاپر به اندازه­های 3 تا 5 سانتی متر خرد شد و در آزمایشگاه به مدت 24 ساعت پژمرده شد. پس از دوره پژمردگی، به سه زیر نمونه تقسیم شد. تیمارهای ­­آزمایشی شامل تیمار یونجه بدون ­افزودنی (شاهد)، یونجه بعلاوه 60 میلی­گرم در کیلوگرم اسانس لیموترش و یونجه­ بعلاوه 120 میلی­گرم در کیلوگرم اسانس هسته­لیمو بودند که به مدت 60 روز در دمای اتاق سیلو شدند. در پایان روز 60، سیلوها باز شدند و بلافاصله pH و ماده خشک اندازه­گیری و باقیمانده نمونه­ها برای اندازه­گیری خاکستر، ADF، NDF و CP در فریزر با دمای 20- درجه سانتیگراد ذخیره شد. آزمایش تولید گاز با استفاده از روش آزمایشگاهی با 5 تکرار در 2 ، 4 ، 6 ، 8 ، 12 ، 16 ، 24 ، 36 ، 48 ، 72 ، 96 و 120 ساعت اندازه گیری شد. داده­های بدست­آمده در قالب طرح­آماری کاملا تصادفی آنالیزگردید. نتایج: نتایج نشان داد که افزودن اسانس­هسته لیمو در هر دو سطح 60 و 120میلی­گرم بر کیلوگرم به سیلاژ یونجه میزان pH سیلو را به طور معنی­داری (05/0p P). اسانس­هسته لیمو باعث افزایش پایداری­هوازی سیلو نسبت به شاهد شد. افزودن اسانس در سطح 60 میلی­گرم گاز تولیدی را نسبت به تیمار شاهد کاهش داد. در کل، داده­های بدست آمده نشان دهنده اثر مثبت اسانس هسته لیمو روی کیفیت سیلاژ یونجه و خصوصیات تخمیری است. نتیجه­گیری­کلی: نتایج این مطالعه نشان داد که افزودن اسانس هسته لیمو بر سیلاژ یونجه باعث افزایش پایداری هوازی سیلو نسبت به شاهد شد. اسانس هسته لیمو تاثیر معنی­داری بر روی ازت امونیاکی و پروتئین خام داشت. سطوح مختلف اسانس هسته لیمو میزان pH را تحت تاثیر قرار داد و به طور قابل­توجهی کاهش یافت. افزودن اسانس هسته لیمو ترش در سطح بالا باعث افزایش میزان تولید گاز و فراسنجه­های تخمیری تولید گاز گردید.
Hyporheic exchange mechanism driven by flood wave

To study the hyporheic exchange driven by a single peak flood‐induced water level fluctuation (i.e., flood wave), a method combining numerical simulation with theoretical derivation was proposed based on the Inbuk Stream, Korea, where flooding occurs frequently. The hyporheic exchanges induced by different flood waves were investigated by varying amplitude (A), duration (T), wave type parameter (r), and rising duration (tp), which were adopted from the real‐time stream stage fluctuations. Additionally, the idea of constant upstream flood volume (CUFV) condition for flood waves was put forward, and the effects of “Botan” (T/A) and peak number (N) on hyporheic exchange were studied. The results showed that the hyporheic exchange flux (q) was controlled by the water level h (sine‐type) and its change rate v (cosine‐type), and was proportional to the polynomial of them q ∝ (ω∙h + v), where ω is the angular frequency of the flood wave. Based on this mechanism, the influence principles on hyporheic exchanges of the typical flood wave parameters (A, T, r and tp) as well as T/A and N under CUFV condition were clarified. The main characteristic variables of hyporheic exchange, which were maximum aquifer storage and residence time, were positively correlated. They also had positive relations to the integral of the flood wave over time, which increased when the wave became higher, wider, rounder and less skewed. However, when CUFV condition was imposed, the residence time was positively correlated with T/A, whereas the maximum aquifer storage was negatively correlated with T/A. With the increase in N, water exchanged more frequently and some water returned to the stream early, leading to the slight decrease in maximum aquifer storage and residence time. These findings enriched the theory of hyporheic exchange driven by surface water fluctuation and be of great significance to enhance pollutant degradation in the hyporheic zone downstream of reservoirs.
Equilibrium Temperatures and Directional Emissivity of Sunlit Airless Surfaces With Applications to the Moon

Solar irradiance dominates the heat flux incident on airless planetary bodies. In thermal equilibrium, surface roughness affects the temperature distribution by changing the incidence angle local to each slope. In order to simulate temperatures and thermal emissions at different phase angles, existing thermophysical models usually employ computationally expensive techniques such as ray tracing. Here we derive the equilibrium surface temperature distribution of sunlit Gaussian rough surfaces, providing an exact solution for the Sun at the zenith and an approximate solution for the general case. We find that although the slope distribution of realistic airless surfaces is often non‐Gaussian, their temperature distribution is well modeled assuming a Gaussian slope distribution. We additionally present closed‐form expressions that describe the radiation emitted from rough surfaces at different emissions angles and employ them to radiometrically estimate the roughness of the lunar surface using measurements obtained by Lunar Reconnaissance Orbiter (LRO) Diviner. Our model may also be applied to studying the roughness of resolved and unresolved surfaces on other airless planetary bodies.
ANGKA HARAPAN HIDUP DI ERA DESENTRALISASI (KABUPATEN/KOTA JAWA BARAT)

This study aims to explains the development of life expectancy (AHH) in West Java Regency / City. Variable of life expectancy in this study is influenced by income (GRDP), access to clean water, mean of years schooling and poverty. The scope of the study was separated into two regional classifications in West Java that were in a condition of life expectancy under the age of 71 and 72 years. The research method used is the panel data method and The Generalized Least Square (GLS) model. The results of this study explain the variable income (GRDP), access to clean water and mean of years schooling have a positive and significant effect on AHH under the age of 71 years. Meanwhile, the independent variables that have a positive and significant influence on life expectancy below 72 years are income (GRDP) and poverty. Income variable (GRDP) becomes an independent variable that affects AHH at age 71 and 72 years.
Environmental Policy and Heterogeneous Labor Market Effects: Evidence from Europe

In this paper, we use a data-driven approach to predict the "green potential" of ISCO occupations based on their corresponding skills. With this information, we can investigate the relationship between environmental regulations and occupation-level employment in the manufacturing sector of 19 European countries for the period 1992-2010. Our empirical results highlight heterogeneous occupational employment changes in response to an increase in environmental policy stringency. More specically, we nd a decrease in labor demand for occupations with relatively low green potential and an increase for occupations with relatively high green potential. Thus, at least in the short term, greening the economy may create winners and losers across occupations and countries.
Ownership Comes with Responsibility – the Impact of Ownership Characteristics on CSR

This article provides a novel methodology to investigate the influence of share ownership on corporate decision making. Quantifying the characteristics of firms’ owners based on their measurable investment habits enables us to assess their predominant preferences. We demonstrate that a preference by owners for eco-social investments is a positive force in their firms’ CSR performance. In contrast, firms exhibit a lower CSR performance when owners show a higher degree of heterogeneity in terms of eco-social preferences. Furthermore, we find that universal as well as long-term ownerships significantly encourage CSR, hence confirming prominent theoretical concepts.
Effect of Seed Treatments and Storage Containers on Viability and Vigour of Rice (Oryza sativa L.) Variety ADT (R) 46 Seeds

Rice (Oryza sativa L.) is an important stable food crop for about 60% of the world's population. The production and supply of quality seed in rice plays a vital role to meet the growing population. It has been shown experimentally that only by using good quality healthy seed, rice yield could be increased by 10-15% (Akter et al., 2015). In rice, there is no much problem in seed storage if the crop is well maintained during production period. Paderes et al., (1997) reported that the germination of rice varieties in storage does not suffer much as compared to other cereals. However, rice seed stored for long-term is invariably exposed to different climatic adversities like extreme summer, winter and monsoons etc. requires a great deal of effort to safeguard it.
Time‐lagged impacts of extreme, multi‐year drought on tidal salt marsh plant invasion

Climate change is projected to increase the frequency of extreme drought events, which can have dramatic consequences for ecosystems. Extreme drought may interact with other stressors such as invasion by non-native species, yet little research has explored these dynamics. Here, we examine the physical mechanisms and temporal scale underlying a dieback of an invasive non-native plant, Lepidium latifolium, in tidal salt marshes of the San Francisco Bay, California, USA, during an extreme, multi-year drought occurring from 2012 to 2015. Using generalized additive mixed models (GAMMs), we explored the relationship between eight years of estuarine salinity data and ﬁ ve years of L. latifolium density data from three marshes spanning a gradient of salinity across the San Francisco Bay. We found a signi ﬁ cant time-lagged (3 yr) effect of estuarine salinity on L. latifolium density, with high salinities preceding reduc-tions in L. latifolium densities and low salinities preceding increases. The most dramatic change in stem density, a 54% reduction in 2015, was preceded by a salinity increase of 43% from 2011 to 2012. We found the L. latifolium decline was driven by impacts on mature, rather than young, plants. Additionally, we tested the importance of local precipitation in driving L. latifolium densities in a one-season rain exclusion experiment. We found 100% exclusion of precipitation during one rainy season (January – mid-May) did not have a signi ﬁ cant impact on densities of mature stands of L. latifolium . Our ﬁ nding that estuarine salinity was a key driver of L. latifolium invasion dynamics suggests sea level rise, like extreme drought, may hinder L. latifolium invasion, as it will also raise estuarine salinities. Further, our study highlights the importance of temporal lags in understanding climate change impacts on biological invasions, which has received very little study to date.
ABIOTIC NITRATE AND NITRITE REACTIVITY WITH IRON OXIDE MINERALS

OF DISSERTATION ABIOTIC NITRATE AND NITRITE REACTIVITY WITH IRON OXIDE MINERALS Under iron (Fe)-reducing conditions where aqueous Fe and unreduced solid Fe-oxides commonly coexist, soil Fe oxidation has been shown to be coupled with nitrate (NO3) reduction. One possible secondary reaction is the involvement of NO3 and nitrite (NO2) with Fe-oxide minerals found in many natural environments. Yet, spectroscopic measurements and kinetic data on reactivity of NO3 and NO2 with Fecontaining oxide minerals such as goethite (α-FeOOH), and magnetite (Fe3O4) are not found in the literature. The reactivity of goethite and magnetite with NO3 and NO2 was studied over a range of environmentally relevant pH conditions (5.5-7.5) with and without added Fe(aq) under anoxic conditions. Laboratory experiments were conducted using stirred batch experiments and reaction products were analyzed using ion chromatography (IC), gas chromatography (GC), ultraviolet visible near infrared spectroscopy (UV-VIS-NIR), x-ray diffraction (XRD), scanning electron microscopy (SEM), Mössbauer, and Attenuated total reflection-Fourier transform infrared (ATRFTIR) spectroscopy. Nitrate removal by goethite and magnetite was much slower when compared with NO2. There was a pH-dependence in the reduction of NO2, and the initial rate of NO2 removal was nearly 2 and 8 times faster at pH 5.5 than at pH 7.5 by magnetite and goethite, respectively. Nitric oxide (NO) and nitrous oxide (N2O) were identified as products when NO2 has reacted with magnetite, whereas N2O is the major reaction product in the experiment with goethite. In comparison to experiments containing magnetite or goethite alone, addition of Fe greatly accelerated the NO2 removal rate. Wet chemical experiments combined with the Mössbauer study reveals that NO2 reduction to NO and subsequently to N2O by magnetite occurs via a heterogeneous electron transfer process. ATR-FTIR and diffuse reflectance spectroscopy (DRS) results from the studies with goethite indicate that NO2 was removed from solution by adsorption in a surface complex involving the oxygen atoms, and a portion of the nitrite is reduced to NO and N2O. This study suggests that under anaerobic conditions soil and sediments that contain goethite, magnetite, and other Fe-oxides can catalyze abiotic NO2 reduction and the kinetics data from this study can be used to predict the NO2 removal under such conditions.

Automatic Attribute Learning for Person Re-Identification

Attribute based person re-identification is more robust to image appearance changes than low-level visual feature based methods. However, manual person attribute annotation has low efficiency, poor scalability and poor discrimination. Therefore, a scalable automatic attribute learning method for person re-identification is proposed. Firstly, the mapping matrix of person attributes is designed and generated automatically according to the principles of discernibility, sharing and low redundancy. Then the visual features are extracted using convolutional neural network and attribute classifiers are trained to detect person attributes, and the attribute based representation of person is generated. Finally, the person re-identification is carried out by comparing the similarity of the attribute based representations. Extensive experiments have been carried out on two common datasets Market-1501 and Duke MTMC-reID with the comparison to the Sate-of-the-Arts methods, the method achieved the best performance, which proves the superiority and effectiveness of the method.
Predictive Role of Cardiac Troponin I, Creatine Kinase-Mb and Electrocardiogram in Early Assessment of Acute Cardiotoxicity in Patients Poisoned by Cardiotoxic Drugs and Toxins

Background: In spite speedy development of clinical toxicology researches and protocols cardiovascular failure in severe acute intoxication remains a leading cause of death. Early cardiovascular risk assessment in acutely intoxicated patients is a must nowadays. This study aims to evaluate the role of ECG, serum cardiac troponin I (cTnI) and creatine kinase myocardial band (CK-MB) for early detection of cardio-toxicity in acutely poisoned patients. Methods: Prospective study was carried on100 patients with acute cardiotoxicity by drugs and toxins known to cause cardiac injury admitted to Sohag University hospitals, informed written consent has been obtained from each patient; ECG and biochemical analysis of serum cTnI and CK-MB were estimated in all studied patients. Results: (90%) of studied patients had complete free recovery, (4%) discharged with complications and (6%) of patients died. ECG test can be used as a predictor of mortality and had sensitivity 100%, specificity 46.8% and negative predictive value (NPV) 100%. Serum cTnI was highly significantly increased with death hence could be used as predictors of outcome. While serum CK-MB couldn't be used as an outcome predictor. ROC curve analysis to assess serum cTnI as a predictor of mortality of acute cardiovascular toxicity with cut off > 1.0 ng/ml had sensitivity 100%, specificity 89.4% and NPV 100% with excellent diagnostic characteristic (accuracy rate 96.4%). There is no significant difference of serum CK-MB and serum cTnI among cardiac drugs toxicity patients and non-cardiac toxins patients. Conclusion: the study concluded that ECG and serum cTnI can be used as a predictor of mortality. Also, the protocol of management will be same in acute cardiotoxicity by cardiac drugs and non-cardiac drugs and toxins. Recommendation: the study recommends combining of ECG changes and serum cTnI as they can early detect acute cardiovascular effects in acutely poisoned patients.
