Study on Chemical Constituents and Antioxidant Activity of Anthocyanins from Ipomoea batatas L. (Purple Sweet Potato)

Anthocyanins extracted from purple sweet potatoes (Iponwea batatas L.) were purified through AB-8 resin column. The extract contains 11 kinds of anthocyanins by HPLC-DAD analysis. The majority of the anthocyanins are acylated cyanidin and peonidin. The objective of this study was to investigate the antioxidant activities of anthocyanins from purple sweet potatoes by different analytical methods: the α, α-diphenyl-β-picrylhydrazyl (DPPH) radical-scavenging effect and superoxide anions radical-scavenging effect, reducing power and antioxidant effect on lipid peroxidation in a linoleic acid model system. At a concentration of 0.5 g/L, the reducing power of anthocyanins, L-ascorbic acid (L-AA) and butylated hydroxytoluene (BHT) reached 0.572, 0.460 and 0.121, respectively. The result displayed that anthocyanins possessed excellent reducing power. The fact that half inhibition concentrations (IC50) of anthocyanins scavenging DPPH radical and superoxide anions radical were 6.94 and 3.68 mg/L respectively indicates that anthocyanins were effective in scavenging DPPH and superoxide anions radical. In addition, anthocyanins could significantly inhibit the peroxidation of lipid.
The non-destructive method of identifying adhesion between a repair overlay and concrete substrate using artificial intelligence

Concrete elements that are exposed to adverse environmental impacts require some non-structural surface repair after some time. After the removal of the corroded surface layer of concrete, a repair overlay is applied in this place, usually of variable thickness. The effectiveness of such repairs with regards to bonding is assessed in construction practice by measuring the value of pull-off adhesion with the use of the pull-off method. However, the repair overlay in this method is damaged at every tested measuring point. This shortcoming significantly affects the reduction of the number of measuring points, which in turn limits the verification of the effectiveness of repair works. In order to eliminate this disadvantage, a non-destructive evaluation of pull-off adhesion between the repair overlay and the surface of the repaired element was proposed. This method is based on the comprehensive use of several research methods and then followed by "corelating" them with the aid of artificial intelligence. The results and analysis obtained in this field are the subject of the paper.
Early Repayment of fixed-rate Mortgages – there is no free Lunch

Providing consumers with the right of early repayment of fixed-rate mortgages at little or no additional charge has been a long-standing demand of consumer groups in mortgage finance. But, given that investors in pools of fixed-rate mortgages face reinvestment risk for the funds they receive (do not receive) from prepayments, there can be no free lunch. Either the additional risk is reflected through an interest rate markup, which renders mortgage loans considerably more expensive – the situation in the US fixed-rate market. Or, to avoid higher rates, the lender adopts call protection strategies, e.g. by charging an indemnity – the situation in the European markets.
Heterosis for seed yield and its components in sesame (Sesamum indicum L.)

An experiment was conducted to know the nature and magnitude of heterosis for seed yield per plant and its eleven yield attributing components. The experimental material used in a study consisted of 37 test entries comprised of 28 hybrids developed from eight diverse parental lines and one standard check (G.TIL 4). The crosses were made in 8 x 8 diallel fashion without reciprocals, to obtain sufficient seeds of the 28 F1 hybrids. The high, significant and positive standard heterosis for seed yield per plant and some of its component traits were recorded in the crosses viz. AT 347 x G.TIL 4, AT 377 x AT 396, AT 396 x AT 404 and AT 376 x AT 377, Such crosses could be exploited for practical heterosis breeding programme in sesame. On the basis of per se performance and high heterotic response involved in the expression of yield and its components, the four crosses viz., AT 347 x G.TIL 4, AT 377 x AT 396, AT 396 x AT 404 and AT 376 x AT 377 appeared to be most superior. These hybrids recorded 22.86, 22.77, 20.51 and 17.17 per cent higher yield respectively, over standard parent (G.TIL 4) in desirable direction for seed yield and some components traits of seed yield. Therefore, these four crosses could be exploited for heterosis breeding programme to boost the seed yield in sesame.
Gamma rays from gravitationally boosted neutralinos at the galactic center

Neutralinos may be gravitationally boosted near the supermassive black hole at the galactic center so that they can have enough collision energy to annihila te into a stau pair. Since in some phenomenologically favored supersymmetric models the mas s splitting between the neutralino and the lightest stau is a few GeVs, this channel may be allowe d. In addition, staus can only decay into a tau lepton and another neutralino. We discuss the m echanisms behind this phenomenon and the gamma-ray spectrum and flux generated by the tau pair.
Target-Free, Flow-Based Calibration for Stereoscopic PIV

An improvement of the process of stereo-PIV calibration is presented. The central feature of the proposed technique is that the calibration of the stereoscopic system is based upon the measurement of a calibrated flow. This is achieved through a first two-dimensional calibration of the measurement plane using a single target point, followed by a perspective and laser sheet thickness optimization that makes use of the measurement of a known flow, e.g. a uniform flow. This technique results in three-dimensional measurements of enhanced accuracy with a simpler calibration phase, which compensates for the mechanical misalignment and eliminates the errors deriving from the classical target dot identification. The technique is particularly well suited for towing tanks and other large facilities, and is applied to the tip vortex system generated by a submarine bridge fin.

IMPACT OF PRODUCTIVITY AND REAL EFFECTIVE EXCHANGE RATE ON THE COMPETITIVENESS OF MANUFACTURING EXPORTS: THE CASE OF CAMEROON

The manufacturing industry in Cameroon is analyzed in this paper. The study, using data from the National Institute of Statistics of Cameroon, covering the period 1993-2008, focuses on the impact of productivity and real effective exchange rate on the competitiveness of manufacturing exports. A production function and an export function are estimated in order to determine the total factor productivity in each industry and manufacturing to measure the effect of productivity and real effective exchange rate on manufacturing exports. The results indicate that the arms meat industry and fish, textile and clothing are the branches where the total factor productivity is important. The export function was estimated for the branches of manufacturing industry; it appears that the total factor productivity has a positive and significant effect at 5%. The real effective exchange rate is significant at 10% after a robust estimate. The manufacturing export performance therefore depends on the one hand appropriate exchange rate and also productivity.
Analysis of Surface Roughness of 2507 Super-Duplex Stainless Steels During Dry CNC Turning Using Deep Cryogenically Treated ISO K313 Wc/Co Inserts

Cryogenics is derived from Greek word “Kryos” which means cold and is combined with the shortened form of English word “Genic” which means to generate. Cryogenics is the Science and Technology that relates to temperature zone below (-1500 C) to near zero Kelvin. In the present study, the analysis of surface roughness of 2507 Super-duplex Stainless steel was done while dry CNC turning using ISO K313 WC/Co inserts which were Deep Cryogenically treated. The Cutting speed (90, 110, 130 m/min), Feed (0.04, 0.06, 0.08 mm/min) and Depth of Cut (0.40, 0.60, 0.80 mm/rev) were the input parameters each having three levels. The results showed that the CT (Cryogenically Treated) inserts performed significantly better and improved the Surface finish of 2507 Super-Duplex Steels than the UT (Untreated inserts). Taguchi’s L9 Orthogonal Array, S/N ratio and Analysis of Variance (ANOVA) were employed in investigating and analysing the data obtained fromexperimentation for evaluating the surface Roughness of steel and also to find the optimal cuttingconditions.

Preventing Postoperative Seroma formation in Abdominal wall Hernia by Intraoperative Hypertonic Saline Irrigation, early Report

Seroma formation (SF) is a common post-operative complication of many operations [1]. Extensive dissection area resulting in a big dead space predispose the accumulation of fluid and the formation of a postoperative seroma and is one of the greatest risk factors for its formation. The larger the surgical intervention, the more likely it is that seromas appear. Plastic and Reconstructive surgeons use techniques like extensive dissecting, development and reposition of myo/fascio/cutaneous flaps and harvesting tissues in order to reallocate them to another area in the body, often leaving a dead space behind them. Therefore, seromas are particularly common after reconstructive surgeries.
Varietal variation of hexane soluble chemical components of Indian mango (Mangifera indica L.) fruit pulp

Hexane soluble non-polar chemical components of fruit pulp of seven Indian Mangifera indica L. varieties were investigated and analyzed by GC-MS. The varieties were ‘Amrapali’, ‘Himsagar’, ‘Fazli’, ‘Langra’, ‘Goplapkhas’, ‘Gopalbhog’, ‘Mohanbhog’. Twenty one aromatic components were identified and some were unidentified components. Multivariate analysis of the identified components indicated that the mango varieties were different on the basis of these non-polar metabolites. The ten most important contributory metabolites for varietal variation were delta-3-carene, beta-myrcene, 1R-alphapinene, beta-pinene, humulene, isocaryophyllene, longifolene, undecane, tetradecane, and alpha pinene.
Modeling longevity risk – the central European case

A longevity risk is any potential risk attached to the increasing life expectancy of pensioners and policy holders, which can eventually translate in higher than expected pay-out-ratios for many pension funds and insurance companies. One important risk to individuals who are spending down savings, is that they will live longer than expected and thus exhaust their savings, dying in poverty or burdening relatives. The main aim of this paper is to point out the view of many random aspects of the problem. We use stochastic approach which is similar to the one applied in modern finance, quantile risk measures, namely the Value at Risk in modeling longevity risk. The calibrations are made for financial and longevity or mortality (equivalently) data from chosen central European countries.
Multivariate analysis approach to select parents for hybridization aiming at yield improvement in Indian mustard (Brassica juncea L.) genotypes

Indian mustard (Brassica juncea L.) germplasm consisting twenty accessions including one National and two zonal check cultivars were evaluated for quantitative traits. The present study was conducted to investigate genetic diversity and correlation among studied genotypes of B. juncea L. based on agromorphological at research farm of TCA Dholi, Dr RPCAU, Pusa, Bihar (India). To investigate the genetic diversity based on morphological characters, data was recorded on eighteen quantitative traits. The calculated data was analyzed through two complementary methods, i.e. PCA (Principal Component Analysis) and cluster analysis. Among all the studied cultivars, significant diversity as well as analysis of dispersion was recorded for different agro-morphological characters. Among all the parameters, maximum variance was recorded forseed yield per plant, biological yield per plant, test weight, harvest index and siliqua on primary branches, secondary branches as well as on primary mother axis. Among all the characters, seed yield had significant and positive association with physiological maturity (1.12G & 0.43P), number of secondary branches (1.00G & 0.78P), silique on secondary branches (0.96G & 0.57P), number of primary branches (0.95G & 0.67) and biological yield per plant (0.90G & 0.81P), plant height (0.74G & 0.46P), silique on primary mother axis (0.73G & 0.49P), silique on primary branches (0.72G & 0.53P), length of primary mother axis (0.52G & 0.29P) at genotypic and phenotypic level. Using cluster analysis all the genotypes were divided into five major groups. It was observed that out 8 of 18principal components with an Eigen value of ≥1.0 calculated for 89.17%% of the total diversity observed between twenty accessions of Indian mustard (B. juncea L.). The contribution of first three PCs in the total PCs was 31.94, 47.29 and 60.00 respectively. Among all the investigated clusters, cluster I and cluster IV showed greatpotential for plant height, number of primary branches, number of secondary branches, siliqua on primary branches, siliqua on secondary branches, siliqua on primary mother axis, biological yield/plant and seed yield/plant respectively, so these genotypes are recommended for future breeding programs for achieving promising results.
Théorie `-adique globale du corps de classes∗

La théorie globale du corps de classes, telle qu’elle fut développée notamment par Takagi, Artin et Chevalley, a pour but principal la description arithmétique des extensions abéliennes d’un corps de nombres donné, à l’aide des seuls éléments de ce corps. Dans sa formulation la plus ancienne, celle de Takagi, elle interprète ainsi le groupe de Galois d’une extension abélienne finie L/K de corps de nombres comme groupe de congruences attaché à un diviseur fL/K construit sur les places ramifiées dans cette extension. Cette description, aujourd’hui encore la plus efficace pour apprécier numériquement une situation donnée, souffre cependant d’être limitée au seul cas des extensions finies. L’introduction par Chevalley des groupes d’idèles, qui relie de façon lumineuse point de vue local et point de vue global, permet de pallier agréablement cette difficulté. Mais d’autres problèmes surgissent alors :
Conflicts of Climate Change Mitigation Actions with the Sustainable Development Goals

Despite a strong connection between the Paris Agreement and the 2030 Agenda for Sustainable Development, climate change mitigation actions and sustainable development objectives are oftentimes not aligned efficiently, causing conflicts between the objectives. This thesis creates a systematic overview of conflicts of three renewable energy technologies with the Sustainable Development Goals (SDGs) by a literature review in Web of Science. The technologies solar energy, wind energy and hydropower function as examples for climate change mitigation actions. Out of 530 screened articles, 63 demonstrated conflicts. The systematic overview reveals that conflicts are different for each technology, but conflicts in regard to biodiversity loss and the degradation of natural habitats (SDG 15) and inequalities (SDG 10) were frequently identified for all technologies. The results of the systematic overview suggest that the site selection and the decision-making process on the construction of renewable energy projects are crucial stages to avoid conflicts with the SDGs. 20_Wuppertaler Studienarbeiten Wuppertal Institut für Klima, Umwelt, Energie gGmbH 6 | Wuppertal Institut Content
Risk factors associated with reproductive disorders in dairy cows in Algeria

In Algeria, there is a lack of information about the prevalence of reproductive health disorders in dairy farms. In this light, the aim of the present study was to determine the effect of parity, body condition score (BCS), calving season, calves’ status at delivery and gender of the calf on the prevalence of dystocia, retained fetal membranes (RFM) and metritis under Algerian field conditions. The study took place from October 2016 to April 2019. It was conducted on 449 dairy cows from 22 commercial dairy farms located in Algerian highland regions (Medea, Tiaret and Tissemsilt areas). The prevalence of dystocia, RFM and metritis was 12%, 16.9%, and 11.8%, respectively. Cows with BCS ≤2.75 were the most affected by RMF (Odds ratio [OR] = 3.66). The main risk factors for RMF were calving abnormalities (OR=3.03), calving in warm season (May to October) (OR= 1.85) and the birth of male calves (OR= 1.75) (P<0.05). Stillbirth, dystocia and RFM were identified as potential risk factors for metritis (P<0.05). These findings confirm again the importance of herd management in prevention of these reproductive disorders.

In addition, several risk models, including the newly defined united risk model and quasi-periodic risk model with interest rate, are studied. 2010 AMS Mathematics Subject Classification: Primary: 91B30; Secondary: 60K10.
Pharmacognosy and radical scavenging potential of different plant parts of Anastatica hierochuntica

The present study was accomplished to explore the proximate analysis and mineral composition in stem, seed and leaves of Anastatica hierochuntica while quantification of secondary metabolites and free radical scavenging were assayed on various extracts of the Anastatica hierochuntica plant material. Proximate analysis exposed the presence of high protein (14.95%) and fat (8.24%) content in seeds, whereas high ash (17.32%) and fibre (13.5%) content in Stems, while Leaves was reported with highest carbohydrate (42.68%) and moisture (14.87%) contents. Results of elemental analysis by ICP shows that leaf has documented to be the highest source of Na(198 ppm), K(395ppm), Ca(346 ppm), Fe(8 ppm), Ba(1069 ppb), Co(25.11 ppb) and Mn(917.43 ppb)while seed for Mg(25 ppm), Ni (66.3 ppb)and Zn(602.2 ppb) whereas Cu(286.2 ppb) was recorded highest in stem. Gallic acid (GA) was taken as standard for phenol, tannin, non-tannins and Quercetin (Q) for flavonoid content. The total phenol was higher in aqueous extracts of leaf (32.25 GAE/g), while non-tannins in aqueous extract of seed (19.84 GAE/g) whereas tannins in aqueous extract of stem (17.36 GAE/g) and flavonoid in methanol extract of leaf (1108.552 QE/g). Trolox and Ascorbic Acid were used as standards for DPPH and ABTS free radical scavenging assays, IC50 value of DPPH assay for seeds methanolic extract was 293 μg/ml which was comparatively lower than trolox (362μg/ml) but Ascorbic acid IC50 value(205 μg/ml) for ABTS assay was lower compared to methanolic extract of seeds(380 μg/ml). These outcomes legitimizes its application in folkloric medicine and scientifically recommends the beneficial use of the plant in the treatment/management of human ailments.
Putrescine as a polyamines and its role in abiotic stress tolerance: A Review

Climate change and global warming consequently causes environmental stresses affecting plant growth and productivity worldwide. Latest estimates suggest that two thirds of the yield potential of major crops are lost due to unfavourable environmental factor or abiotic stressors. Food shortage will be the common phenomenon in near future as the world population will reach about 10 billion by 2050. Therefore in order to feed the burgeoning population it is an urgent need to develop crop plants with enhanced vigour and high tolerance to various unfavourable environmental abiotic stressors. Maintaining yield stability under adverse environmental conditions is a major challenge faced by the modern agriculture in which the polyamines play a very important role in mitigating the devastating effect of various environmental factors. Polyamines (PAs) (putrescine, spermidine and spermine) are group of phytohormone-like aliphatic amine natural compounds with aliphatic nitrogen structure and present in almost all living organisms including plants. Among Polyamines, putrescine has more importance since it is the principal component and precursor for tertiary and quaternary PAs. Earlier studies proved that it is having role in diverse physiological processes such as flower development, embryogenesis, organogenesis, senescence, and fruit maturation and biotic and abiotic stress tolerance. Many studies suggested the probable mechanism of abiotic stress tolerance induced by putrescine which includes assisting an compatible solutes proline, glycine betaine and GABA in dehydration tolerance, stabilization of macromolecules and organellar membrane, inducig the production of antioxidant enzymes, playing as signal molecules in ABA regulated stress response pathway, regulators of several on channels, role in metabolic regulation of ammonia toxicity and nitric oxide (NO) production and regulating programmed cell death. Therefore, genetic manipulation of crop plants with genes encoding enzymes of polyamine biosynthetic pathways may provide better stress tolerance to crop plants. Furthermore, the exogenous application of PAs is also another option for increasing the stress tolerance potential in plants. Here, we have described the synthesis and role of various polyamines in abiotic stress tolerance in plants.
