Impact of eight closures in controlled industrial conditions on the shelf life of two (red and rosé) wines

Aims: The management of O2, CO2 and SO2 at bottling and the choice of closure are two key factors of the shelf life of bottled wines before bringing them to market. The impact of eight closures (four screw caps, two synthetic stoppers and two technical stoppers) was evaluated on a red Merlot/Tannat wine. The results of a rose wine are also discussed. Methods and results: Analytical monitoring (O2, CO2, SO2, aphrometric pressure, L*, a*, b*) was carried out over 538 days of storage at 20°C, along with two sensory analyses at 10 and 17 months. The average wine total O2 content at the time of bottling was 2 mg/L. Intra- and inter-procedure variability was controlled, including for dissolved CO2 content. Conclusion: Unlike closures with the highest Oxygen Transmission Rate (OTR), the two technical stoppers and the two screw caps with Saranex seal, harboring the lowest OTR, matched with the wines exhibiting a low total O2 content at equilibrium (from 4 to 18 months after bottling), with more free SO2 and less color change. However, the OTR gradient (5 to 67 µg/d) observed through the physicochemical analyses was not necessarily confirmed by the two sensory analyses. Significance and impact of the study: This study puts into perspective the impact of closure OTR on the sensory characteristics evolution of wine consumed within the first two years, especially when total O2 at bottling exceeds 1.5 mg/L.
Self supervised learning improves dMMR/MSI detection from histology slides across multiple cancers

Microsatellite instability (MSI) is a tumor phenotype whose diagnosis largely impacts patient care in colorectal cancers (CRC), and is associated with response to immunotherapy in all solid tumors. Deep learning models detecting MSI tumors directly from H&E stained slides have shown promise in improving diagnosis of MSI patients. Prior deep learning models for MSI detection have relied on neural networks pretrained on ImageNet dataset, which does not contain any medical image. In this study, we leverage recent advances in self-supervised learning by training neural networks on histology images from the TCGA dataset using MoCo V2. We show that these networks consistently outperform their counterparts pretrained using ImageNet and obtain state-of-the-art results for MSI detection with AUCs of 0.92 and 0.83 for CRC and gastric tumors, respectively. These models generalize well on an external CRC cohort (0.97 AUC on PAIP) and improve transfer from one organ to another. Finally we show that predictive image regions exhibit meaningful histological patterns, and that the use of MoCo features highlighted more relevant patterns according to an expert pathologist.
Croissance de cristaux facettes : cas de WC-Co

Les carbures cementes wc-co sont constitues de deux phases : une phase liante, solution solide a base de co, et une phase wc, majoritaire presentant generalement des grains facettes. Ils sont prepares par metallurgie des poudres et une densification quasi totale est obtenue par frittage avec phase liquide. Durant cette etape, une evolution microstructurale, nefaste pour les proprietes mecaniques, se produit. Cette evolution correspond a une croissance des grains de wc normale (augmentation uniforme de la taille) et anormale (apparition de tres gros grains), et apparait bloquee par l'ajout en faible quantite de certains elements dits inhibiteurs tels que v ou cr. Afin de cerner le(s) mecanisme(s) mis en jeu, l'influence de divers parametres sur la croissance est caracterisee par analyse qualitative (meb, met) et quantitative. Cette derniere est realisee par analyse d'images meb en mesurant les distributions de taille d'intercepts dans la phase wc. Les facteurs etudies sont : la granulometrie de la poudre wc, la composition du liant (rapport c/w), la presence de la phase graphite ou m 6c, un ajout de v ou cr, la fraction de liant, la densite a vert des comprimes, le broyage du melange de poudres, la temperature de frittage et la vitesse de refroidissement. Un minimum de deux temps de frittage (dont un de quelques minutes) est realise. A partir des resultats experimentaux, le grossissement parait produit principalement par dissolution-precipitation, la contribution de la coalescence restant limitee. L'analyse de l'enthalpie libre du liquide a base co montre une grande metastabilite, qui explique la croissance faible et limitee pour des particules microniques et la croissance anarchique dans les populations submicroniques, et une stabilite un peu moins grande pour les compositions riches en c, coherence avec la croissance plus reguliere pour de telles compositions. Cette analyse suggere en outre que la germination de graphite peut activer la germination 2d de wc.
Energy storage and control optimization for an electric vehicle

Two big issues involving electric vehicles are energy supply and power management control. To deal with the energy supply problem, this paper proposes the application of a hybrid energy source system, composed of battery pack and ultracapacitor bank. The power management control between the energy supplies was defined by a fuzzy logic with inference rules optimized through genetic algorithm. The genetic algorithm optimizes lower and upper limits of membership functions aiming to reduce the hybrid energy source system total mass while maximizing the electric vehicle drive range and performance. Through the Pareto frontier, we found the best trade‐off solution.
The Status of Serum Zinc, Magnesium and Calcium in Type 2 Diabetic Patients and Their Correlation with Renal Function.

Trace elements play significant roles in the metabolism of insulin. The aim of this study is to investigate the level of serum zinc, magnesium and calcium in type 2 diabetes mellitus and relate them with the functionality of kidneys. 200 diabetic individuals and 50 healthy controls were enrolled. For each individual, blood sugar, serum urea and serum creatinine were determined. In addition, serum zinc, magnesium and calcium were determined for each individual via flame atomic absorption spectrometry. Significant differences were found in the level of serum zinc and magnesium between diabetic and healthy control groups. However, there was not any difference in the level of serum calcium between the two groups. It is not certain whether the low level of serum zinc and magnesium cause diabetes or they are the consequence of development of diabetes. The level of serum trace elements did not correlate with the functions of kidneys.
Phenolic profiles, antioxidant and antimutagenic activities of Solanum lycopersicum var. cerasiforme accessions from Mexico

ABSTRACT The fruit of 18 Solanum lycopersicum var. cerasiforme accessions from Mexico were evaluated for total phenolics (TP) by the Folin-Ciocalteau assay, phenolic profiles by high performance liquid chromatography-diode array detection-mass spectrometry (HPLC-DAD-MS), antioxidant activity (AoxA) by 2,2´-azino-bis(3-ethylbenzothiazolin)-6-sulfonic acid (ABTS), 2,2-diphenil-1-pycrilhydrazyl (DPPH), and oxygen radical absorbance capacity (ORAC), and antimutagenic activity (AmuA) by the Ames assay. TP was measured as Gallic Acid Equivalents (GAE) and the AoxA as Trolox Equivalents (TE). TP varied from 37 to 86 mg GAE 100 g−1 fresh weight (fw). The AoxA by ABTS (568-1187 µmol TE 100 g−1 fw) and DPPH (157-350 µmol TE 100 g−1 fw) correlated with TP and the levels of caffeoylquinic acids and rutin. The AmuA did not correlate with the levels of phenolics. Some accessions had higher AoxA and AmuA than those reported for commercial cultivars and also showed high levels of caffeoylquinic acids and rutin; thus, their consumption could have good health promoting effects.
Students’ perspective on the effectiveness of the third-year accounting project in developing SAICA competencies.

Examiners have identified gaps in certain pervasive and technical skills when analyzing students’ answers for the South African Institute of Chartered Accountants’ (SAICA) Initial Test of Competency (ITC). It has been observed that students are not able to apply logical thinking, argue and reach conclusions on issues, which are some of the skills expected from the profession. This results in newly-qualified chartered accountants (CAs) being under-prepared to work in the industry. This study aimed to establish students’ perceptions of how the University of Zululand’s (UniZulu) third-year Bachelor of Commerce in Accounting Studies project enhanced these competencies in preparation for the CA qualification. The project aims to develop the personal attributes and professional skills set out in the SAICA Competency Framework. Personal attributes include working effectively as a team, planning, effectively managing the project and treating others professionally. Professional skills involve gathering, analyzing and critically interpreting information and ideas in order to make sound decisions to solve problems and communicate effectively. A quantitative approach was employed and the study population consisted of third-year UniZulu Accounting students. A questionnaire was developed to address the identified issues. The study’s results that are supported by the literature indicate that working on projects is a more effective tool than lectures in developing these competencies and enhancing students’ understanding of the profession’s requirements.

Antioxidant Evaluation of Baccharis patens and Baccharis psiadioides Essential Oils

Abstract The chemical composition of the essential oil of Baccharis patens Baker leaves was analyzed for the first time in the literature, by GC-MS and GC-FID. The antioxidant activity of B. patens and B. psiadioides (Less.) Joch. Müll. essential oils was determined by DPPH radical scavenging method. The oil was a complex mixture of terpenes, with 57 identified compounds. Sesquiterpene hydrocarbons were the main fraction (37.13%). Thymol, a standard antioxidant, showed 90% of antioxidant activity at 20 mg/mL. At a higher concentration, 100 mg/mL, B. patens and B. psiadioides essential oils resulted in 42% and 50% of antioxidant activity, respectively. Comparable antioxidant activity of the essential oils may be due to the similar low activity of their major compounds.
The effect of amphipilic lignin derivatives addition on enzymatic hydrolysis performance of kraft pulp from sorghum bagasse

Previously, the chemical characteristics of isolated lignin from Acacia mangium black liquor of kraft pulping was characterized. This lignin was blended with natural rubber latex (NR-L) as adhesive in laminated wood. In addition, lignin has potency for biosurfactant materials by modification of the hydrophobic into hydrophilic properties. Therefore, this study was intended to develop lignin as material for amphipilic lignin derivatives (A-LD) biosurfactant by reacting lignin with epoxilated polyethylene glicol (PEG). A-LD addition in slurries was used to improve the enzymatic hydrolysis (EH) of kraft pulp sweet bagasse sorghum (SSB). The main observation in EH performance was to investigate the effect of lignin isolation method (one and two step) in A-LD and A-LD loading addition on reducing sugar yield (RSY) of SSB kraft pulp. The pulp was hydrolyzed at 50°C and 150 rpm for 72 h with 10 FPU cellulase loading in the shaking incubator. A-LD from one (L1S) and two step (L2S) lignin was added with A-LD loading of 0, 1, 2, 5, and 10% (b/v). The RSY of hydrolyzate has been observed after EH. A-LDs addition in EH of SSB kraft pulp enhanced RSY. L1S worked better in reaction performance with PEDGE compared to L2S and LS. A better performance was showed by PEDGE 500 than that of PEDGE 6000. Generally, the higher A-LDs loading resulted higher RSY. The highest RSY (81.33%) was resulted in addition of 10% A-LD L1S using PEDGE 500. A 5% A-LD loading was more considered to be added in EH because the RSY was comparable with 10% A-LD loading.
The Mediating Effects of Trustworthiness on Social‑Cognitive Factors and Knowledge Sharing in a Large Professional Service Firm

Abstract: This paper extends the findings of a large empirical study of organizational information and knowledge sharing that examined the interplay of several notable social and cognitive factors, including trust, shared language, shared vision, tie strength, homophily, and relationship length. Initial data analysis examined the direct, relative, and collective effects of these social and cognitive factors on organizational knowledge sharing factors (Evans, 2012). The results of this analysis demonstrated that co‑worker trust influences, in a statistically significant way, each factor used to operationalize organizational knowledge sharing, namely: willingness to share knowledge, willingness to use knowledge, and perceived receipt of useful information/knowledge (Evans, 2013). This study presents the results of a secondary data analysis, which examines whether perceived trustworthiness in co‑workers acts as a mediating variable between the previously mentioned social‑cognitive variables and knowledge sharing factors. Data were collected from 275 knowledge workers (legal professionals and paralegals) engaged in shared legal project work, at one of Canadas largest multijurisdictional law firms. The nature of their work requires a significant reliance on co‑workers, across offices nationwide, for both explicit and tacit information and knowledge. The nature of projects allows respondents to objectively evaluate the outcomes, gaining a better sense of the perceived effects of knowledge shared. A method put forward by Baron and Kenny (1986), which includes hierarchical multiple regression analysis, was used to test for the mediating effects of perceived co‑worker trustworthiness. The results of the study showed that the relationship between shared language and shared vision on information and knowledge sharing is mediated through perceived trustworthiness. Moreover, this mediation is subject to the nature of the relationship between co‑workers. For shared language, the role of co‑worker relationship is still more nuanced as perceived trustworthiness was found to have a mediating effect between shared language and knowledge sharing in relationships between co‑workers with whom they worked well together on projects only. There is no apparent mediation of trust for shared language in negative co‑worker relationships, which demonstrates one of the few interesting effects found to be dependent on the nature of the co‑worker relationship.
Phytochemical profile and antimicrobial properties of volatile compounds of Satureja calamintha (L) Scheel from northern Algeria

Purpose: To undertake the phytochemical screening of Satureja calamintha (L.) Scheel. , and evaluate the antimicrobial activities of its volatile compounds. Methods : Qualitative phytochemical analysis of the plant was performed using standard methods. The extraction of essential oils (EOs) was conducted using steam distillation, while the chemical composition was determined using gas chromatography-mass spectrometry (GC-MS). The antimicrobial activities of the oils were evaluated against ten bacterial and six fungal strains using disc-diffusion assay and poisoned food technique, respectively. Results: After steam distillation, the extraction yield was 0.54 ± 0.11 %. GC-MS analysis identified approximately 99.99 % of the EOs. The three most abundant compounds identified were l-menthone (32.10 %), neo-menthol (32.07 %) and pulegone (22.35 %). The oils had significant (p < 0.05) antimicrobial activities against the tested bacterial and fungal strains, except Bacillus cereus and Candida albicans. The lowest minimum inhibitory concentration (MIC) for bacteria was 0.007 % (v/v) against Enterococcus faecalis and Klebsiella pneumoniae , whereas for fungi, it was 0.500 % (v/v) against Candida albicans. Moreover, Enterococcus faecalis and Listeria innocua had the lowest minimum bactericidal concentration (MBC) at 0.125 % (v/v), in contrast to the lowest fungicidal concentration (MFC) for Candida albicans at 0.500 % (v/v). Conclusion: These results demonstrate that EOs from Satureja calamintha (L.) Scheel. possess significant antimicrobial activities which might be useful for therapeutic and pharmaceutical applications. Keywords: Satureja calamintha , Phytochemicals, Essential oils, Antimicrobial activity, Steam distillation
Determination of Sm‐Nd Isotopic Compositions in Fifteen Geological Materials Using Laser Ablation MC‐ICP‐MS and Application to Monazite Geochronology of Metasedimentary Rock in the North China Craton

In this study, we report both 143Nd/144Nd and 147Sm/144Nd values in twelve minerals (apatite, titanite, monazite and eudialyte) based on analyses over 4 years using LA‐MC‐ICP‐MS. The positive correlation between the measured βSm and βNd (r2 = 0.9981) over this time in our laboratory demonstrates the excellent long‐term stability of the method. Compared with the normal method, Sm and Nd signal intensities were improved by a factor of 2.9 with the use of X skimmer and Jet sample cones in combination with the addition of nitrogen at 3–6 ml min−1 to the central gas flow. The enhancement of signal intensity benefits the accurate in situ determination of the Sm‐Nd isotopes of samples poor in these elements. 143Nd/144Nd values were also determined in two manganese nodules and GSMC Co‐rich crust with low mass fractions of Nd (94–293 μg g−1). Generally, most of the obtained Sm‐Nd isotopic compositions in these geological materials are consistent with published values. ‘External reproducibility’ (2s) of 143Nd/144Nd and 147Sm/144Nd was typically better than 0.06‰ and 2.5‰, respectively, demonstrating that the Durango, Otter Lake, NW‐1 and MAD apatites, the Khan, and OLT‐1 titanites, MGMH#117531 monazite and LV01 eudialyte are promising candidate reference materials for in situ Sm‐Nd isotopic determinations. The Trebilcock, Mae Klang and 44069 monazites are only suitable for in situ Nd isotopic determinations because of their heterogeneous Sm/Nd compositions. The heterogeneous Sm‐Nd composition of titanite BLR‐1 demonstrates that it is not a suitable reference material for in situ Sm‐Nd isotopic determinations. Deep‐sea samples (NOD‐A‐1 and NOD‐P‐1 manganese nodule, GSMC Co‐rich crust) with low mass fractions of Nd also show homogenous Nd isotopic compositions. Sm‐Nd isotopic ratios of a monazite (MQG‐22) from the North China Craton were measured as a case study and gave a 147Sm‐143Nd isochron age of 1792 ± 35 Ma (MSWD = 3.2) consistent with the published metamorphic age of the host metasedimentary rocks. The results for both candidate reference materials and geological samples demonstrate that the in situ LA‐MC‐ICP‐MS analytical protocol described is feasible and robust for research in geological evolution.
Related Party Transactions and Earnings Management: An Empirical Examination of Selected Companies in India

A number of publicized accounting frauds around the world, such as Satyam fraud (India), Enron failure (USA), Tyco failure (Ireland), show that firms use Related Party Transactions (RPTs) to manage earnings for financial reporting purposes or to divert firms’ resources to their controlling shareholders at the expense of minority shareholders. This study aims to explore the relationship between RPTs and earnings management practices of selected companies in India. The amount of discretionary accruals derived from modified Jones models (Dechow et al., 1995) is used as a proxy to measure earnings management. Based on 218 firm-year observations taken from BSE-200 index based companies for the financial year 2014 and 2015, this study finds that there is a statistically significant relationship between RPTs and earnings management. The findings also reveal that the effect of new RPT regulations in mitigating earnings management is not significant.
EFFECT OF VARIOUS RATES OF BORON ON YIELD AND QUALITY OF HIGH-GRADE SUGAR BEET VARIETIES

Cukrova řepa je kulturni plodina kladouci vysoke naroky na půdni vlastnosti, pravidelna a vcasně uplatňovana agrotechnicka opatřeni, spravný výběr odrůd ve vztahu k chorobam listů a bulev, ochranu a spravne hnojeni vychazejici z výsledků chemických a mikrobiologických rozborů. Kromě hnojeni makroprvky (dusik, fosfor, draslik) je velmi důležite aplikovat bor jako mikroprvek. Nedostatek boru vede ke sniženým výnosům bulev a obsahu cukru v řepě. Je to proto, že se bor podili na procesu transportu cukru do bulev rostliny. Největsi potřeba boru je v obdobi intenzivniho růstu listů od uzavřeni řadků (konec května a zacatek cervna) po dosaženi maximalni plochy listů (polovina cervence). Zavaděni nových výnosných odrůd cukrove řepy vyžaduje ve větsině připadů (v zavislosti na dostupnosti boru v půdě) větsi davku boru. Výzkum byl proveden na dvou lokalitach během dvou vegetacnich let (2015, 2016). Experimenty byly provedeny ve schematu dělených bloků ve 12 variantach a 4 opakovanich na dvou různých půdnich typech. Byla použita tato osetřeni: A) odrůdy cukrove řepy (A1 – Jadranka, KWS, A2 – Antek, Strube, A3 – Protecta, Syngenta-Hill, A4 – Boomerang, SESVanderHave) ; B) hnojeni borem (B1 – kontrola, B2 – 1 kg/ha B, B3 – 2 kg/ha B). Hnojeni bylo provedeno na zakladě chemicke analýzy půdy. Oba půdni typy byly hnojeny takto: na půdni typ typicka hnědozem bylo aplikovano 95 kg/ha N, 65 kg/ha P2O5, 220 kg/ha K2O a na půdni typ organozemni glej bylo aplikovano 85 kg/ha N, 50 kg/ha P2O55, 200 kg/ha K2O. Bor byl aplikovan na listy v podobě boritanu sodneho (Borax, 37 % boritanu sodneho ; Ekoprom d.o.o.). Byla provedena dvě osetřeni listů, jedno před uzavřenim řadků a druhe o 14 dnů později. Po sklizni byly odebrany vzorky pro urceni výnosu kořene i kvality řepy. Ve srovnani s kontrolni variantou dosahly obě varianty hnojeni borem statisticky významně vyssich výnosů, cukernatosti a výnosu cukru na obou půdnich typech a u vsech testovaných odrůd. Zatimco na půdnim typu typicka hnědozem bylo nejlepsich výsledků u vsech testovaných parametrů dosaženo variantou B3 (2 kg/ha B), v připadě půdniho typu organozemni glej nebyly mezi variantou B2 (1 kg/ha B) a B3 (2 kg/ha B) zjistěny žadne statisticky významne rozdily, kromě výnosu cukru.
Leadership and employees’ productivity: Measuring an impact of three selected leadership styles on employees’ productivity in the banking sector of Bahawalpur, Pakistan

This study was founded on the need to establish the influence of three leadership styles on employee productivity at banking sector of Bahawalpur. To achieve objectives of study, a descriptive survey was used to determine the influence of three leadership styles (task-oriented leadership, autocratic leadership, charismatic leadership) on employee productivity. Target population of study included all managers and employees of Bahawalpur’s Banks. A sample size of 234 was selected from a population of 586 managers and employees. Data was analyzed using correlation and regression analysis. Results of study showed that all three leadership styles have a positive relation with employee productivity. Study found that a unit increase in autocratic leadership style, task-oriented leadership style and charismatic leadership style leads to increase in employee productivity. Study, therefore, recommends that leaders know what is important for subordinates and organization as a whole and encourage employees to see opportunities and challenges around them creatively. Study suggests that a similar study can be done in other banks of Punjab and Pakistan by using other leadership styles.
