Effect of different irrigation strategies on vine physiology, yield, grape composition and sensory profiles of "Vitis vinifera" L.Cabernet-Sauvignon in a cool climate area

Aim: The efficacy of partial root zone drying (PRD) and regulated deficit irrigation (RDI) on vine physiology, yield components, fruit composition and wine sensory profiles of ‘Cabernet-Sauvignon’ was investigated in a cool climate region in Ontario, Canada.Methods and results: Field experiments were conducted in a Cabernet-Sauvignon block in Niagara-on-the-Lake, ON Canada between 2006 and 2008. There were five treatments : non-irrigated control, PRD, full irrigation [100 % of crop evapotranspiration (ETc)] and two levels of RDI (50 and 25 % ETc). Treatments started immediately after fruit set and continued until post-veraison. Soil and vine water status were apparently controlled not only by the amount of water but also by the irrigation strategy used. In the PRD treatments, soil moisture, leaf water potential, and transpiration rate were generally lower than in 100 % ETc but higher than non-irrigated and RDI treatments. Almost all treatments were different than in non-irrigated vines in fruit composition and wine sensory attributes. Wine sensory attributes differed considerably due to the amount of irrigation water applied in 2007. RDI strategies were more consistent than the PRD treatments in their effect on vine water status, grape composition and wine sensory profiles. Inconsistent patterns across seasons for some variables indicated that besides soil and vine water status, there were other factors that impacted vine physiology, yield components and berry composition.Conclusions: RDI treatments improved wine quality when compared with full or either non-irrigated treatments. Overall, use of RDI irrigation or PRD during dry and warm years can improve grape composition in cool climates.Significance and impact of the study: To the best of our knowledge, this is the first evaluation of PRD and RDI on Cabernet-Sauvignon in a cool humid climate. It suggests that although RDI strategies are more effective, PRD also has value, particularly in dry seasons.
Preparation, Characterization, and Evaluation of Poly(p-azidoaniline) as Thermal Stabilizer for Low Density Polyethylene Films

ABSTRACT A series of electrically conducting low density polyethylene/poly(p-azidoaniline) blends containing different loadings of poly(p-azidoaniline) was prepared. The resistance of these blends to accelerated thermal oxidation at 90°C for different time intervals was investigated. The thermal degradation mechanism was determined by attenuated total reflection-Fourier transform infrared technique. The values of melting temperature (Tm), enthalpy of fusion (ΔHm), and degree of crystallinity showed significant increase upon poly(p-azidoaniline) addition. X-ray diffraction patterns also confirmed increase in degree of crystallinity upon blend formation. Furthermore, scanning electron microscopy observations showed efficient thermal stabilization of low density polyethylene/poly(p-azidoaniline) blends. The mechanical properties showed significant role of poly(p-azidoaniline) as thermal stabilizer for low density polyethylene. GRAPHICAL ABSTRACT

Influence of coating and packaging material on physicho-chemical characters and shelf life of custard apple (Annona squamosa L.)

Present investigation to study the influence of coating and packaging material on physico-chemical characters and shelf life of custard apple (Annona squamosa L.) cv. Balanagarframed in Factorial Completely Randomized Design (FCRD) with twelve treatments and three replications was during conducted during 2018. The experiment comprised of two factors namely coating (with and without wax coating) and 50 µ low density polyethylene bags (with 0.5%, 1%, 1.3% and 2% perforation, without perforation) and Punnet box. Matured fruits of uniform size, firm, free from pest, diseases and injuries were selected. For coating, fruits were dipped in aqueous solutions of bees wax for 5 minutes and dried for 30 minutes at room temperature. According to the treatment, fruits were packed in polyethylene bags and punnet and observation on changes in physic-chemical characters during storage on2nd, 4th, 6th, and 8th day and shelf life were recorded. Results revealed that there was significant impact of interaction among wax coating and packaging material on all parameters studied. When considered interaction, the treatment C2P5i.e. fruits coated with wax and packed in 50 µ low density polyethylene bags without perforation, had maximum TSS, total sugars, and minimum reduction of moisture per cent. This treatment registered the highest TSS (25.05 0Brix), total sugar (22.24%), least reduction in moisture (77.26%) and shelf life of 8 days. Overall results indicated the wax coating and packaging of custard apple fruits in 50 µ polyethylene bags (without perforations) improved the shelf life and at the same retained quality of fruits and the treatment combination C2P5i.e. fruits coated with wax and packed in 50 µ low density polyethylene bags without perforation was found to be promising.
Accuracy of ultrasound-guided fine needle aspiration cytology (US-FNAC) to detect axillary involvement in breast cancer

Received on: July 2, 2020 | Accepted on: November 6, 2020 DOI: https://doi.org/10.5935/2526-8732.20200044 Introduction: Axillary involvement is one of the main prognostic factors in breast cancer. This study aimed to assess the accuracy of ultrasound-guided fine needle aspiration cytology (US-FNAC) to detect axillary involvement in breast cancer and to compare with other methods of axilla assessment: axillary palpation (AP) and isolated axillary ultrasound (A-US). Methods: A retrospective accuracy study was performed using data from medical records of patients assisted at a breast cancer service in Recife, Brazil, between 2013 and 2017. A histopathological result (sentinel lymph node and/or axillary dissection) was adopted as a gold standard. Sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of the AP, the A-US and US-FNAC were calculated. Results: 206 tumors were analyzed. The AP was truly positive in 34.0% of the results similar values were obtained for A-US (36.4%). The lowest incidence of false negative was in the US-FNAC (16.5%). Axillary involvement was identified in 82 (39.8%) cases. The US-FNAC was performed in 79 cases, 51 (64.5%) were identified as true positive and 13 (16.5%) were false negative. When analyzing the comparative results of AP, A-US and the US-FNAC of the axilla with histopathology, it was observed that AP presented an accuracy of 69.9% (95%CI=63.1-76.1), better than the A-US, which its accuracy was 68% (95%CI=61.1-74.3). The US-FNAC showed high specificity (100%, 95%CI=81.9-100%), of PPV at 100% (95%CI=94.3-100%), but with a low NPV (53.6%, 95%CI=33.9-72.5). The best NPV was the AP (59.7%, 95%CI=50.5-68.4). The US-FNAC accuracy was 83.5% (95%CI=73.591.0). Conclusion: The good accuracy associated to the high specificity and the PPV of the US-FNAC suggests it to be a promising examination in the diagnosis of axillary involvement in breast cancer and an ally to better define therapeutic conducts.

RL-Recruiter+: Mobility-Predictability-Aware Participant Selection Learning for From-Scratch Mobile Crowdsensing

Participant selection is a fundamental research issue in Mobile Crowdsensing (MCS). Previous approaches commonly assume that adequately long periods of candidate participants’ historical mobility trajectories are available to model their patterns before the selection process, which is not realistic for some new MCS applications or platforms. The sparsity or even absence of mobility traces will incur inaccurate location prediction, thus undermining the deployment of new MCS applications. To this end, this paper investigates a novel problem called “From-Scratch MCS” (FS-MCS for short), in which we study how to intelligently select participants to minimize such a “cold-start” effect. Specifically, we propose a novel framework based on reinforcement learning, named RL-Recruiter+. With the gradual accumulation of mobility trajectories over time, RL-Recruiter+ is able to make a good sequence of participant selection decisions for each sensing slot. Compared to its previous version, RL-Recruiter, Re-Recruiter+ jointly considers both the previous coverage and current mobility predictability when training the participant selection decision model. We evaluate our approach experimentally based on two real-world mobility datasets. The results demonstrate that RL-Recruiter+ outperforms the baseline approaches, including RL-Recruiter under various settings.
The Differentiated Impact of the Institutional Environment on Eco-Innovation and Green Manufacturing Strategies: A Comparative Analysis Between Emerging and Developed Countries

This article argues that institutional environments have different impacts on the association between a strategic orientation to eco-innovation and green manufacturing (GM), depending on the countries’ degree of development and type of market. A survey drew 172 responses from manufacturing firms from emerging countries (Brazil and India) and 130 responses from developed countries (Germany and the USA). The results showed that institutional regulatory pressures impact firms in emerging markets at a strategic level, putting pressure on an orientation aimed at eco-innovation. In contrast, consumer market pressures have an effect on developed markets at the execution level, directly impacting GM activities. The main contribution of this article demonstrates that different institutional environments consist of induction factors applied to the competitive strategy of innovation management (strategic orientation for eco-innovation) and engineering (GM). Our results reveal that institutional impulses generated by the dimensions of consumer pressure or by a market's regulatory framework may differ. In this sense, the patterns of institutional maturity and environmental maturity of the markets are equally important in inducing the development of eco-innovative and GM capabilities. The evidence provides insights for managers in both developed and emerging markets about the drivers of institutional environments in different contexts and about how management strategies aimed at eco-innovation and GM should be guided.
Strategic Dual Citizenship: Global Dynamics of Supply and Demand

The growing toleration of dual citizenship changes the basic rules governing citizenship attribution. It creates new possibilities for legal connections between states and individuals, including overlapping memberships and belonging from a distance. In this chapter, I argue that the legitimisation of dual citizenship leads to the adoption of strategic policies on the part of states (the “supply” side) as well as on the part of eligible individuals (the “demand” side). Numerous states use dual citizenship policies to select new citizens that do not live on their territory and do not intend to relocate or give up their original citizenship. These include the descendants of emigrants (e.g. Italian descendants in South America who are now offered Italian citizenship), cross-border co-ethnics (such as ethnic Hungarians in the countries surrounding Hungary), as well as millionaires from developing countries who can now – for a hefty sum – acquire citizenship from a country where they have never set foot. From the perspective of eligible individuals, such schemes offer opportunities to strategically expand their scope of rights and opportunities by acquiring a second citizenship that is ranked higher in the global hierarchy of citizenship value. The expected benefits may include global travel freedom, an insurance policy and broader economic opportunities. These developments, which impact both states and individuals, weaken the traditional association between citizenship and national identity.
Classical Maple Syrup Urine Disease successfully treated with living donor liver transplantation

Maple syrup urine disease (MSUD) is a disease that causes ketoacid accumulation in body. Diffusion-weighted imaging (DWI) is an important imaging modality for the diagnosis. Two children were diagnosed with MSUD at the neonatal period. They had uncontrolled ketosis and epileptic seizures although they were in compliance with their medical nutrition. Their DWIs were similar and showed high signal intensity localized within the myelinated white matter areas. Both of the patients were treated with living donor liver transplantation. The patients with classic form of MSUD are normal at birth. If the disease is not diagnosed and treated early, it can lead to serious neurological complications. Most researchers conclude that, the best choice for detecting MSUD encephalopathy in newborns is DWI. The traditional treatment of MSUD had been a protein-restricted diet until the liver transplantation became an alternative and better option for the cure of the patients.
Effects on Oxygen‐barrier Properties of Pretreating Paperboard with a Starch–Poly(Vinyl Alcohol) Blend before Polyethylene Extrusion

Polyethylene (PE) extrusion coating was performed on paperboard pre‐coated with water‐borne barrier coatings based on starch–poly(vinyl) (PVOH)–plasticizer blends in order to investigate that how the addition of a plasticizer to the pre‐coating affects the oxygen‐barrier properties of the board after PE extrusion coating. The plasticizers used were glycerol, polyethylene glycol (PEG) and citric acid (CA). Photomicrographs showed that the barrier coating layers were rather smooth, but defects were observed in the starch–PVOH layers when a plasticizer was added. Starch–PVOH layers had oxygen‐barrier properties similar to those of pure PVOH without plasticizers. When a sufficient number of layers (four layers) were applied to cover defects, the starch–PVOH layers containing CA showed oxygen transmission rate (OTR) values similar to those of starch–PVOH layers without plasticizer. The adhesion of PE to pre‐coated paperboard decreased when a plasticizer was added to the pre‐coating recipes. PE extrusion coating resulted in a reduction in the OTR in the case of pre‐coating formulations containing plasticizers. A lower OTR after polyethylene extrusion was observed with PEG as plasticizer than with CA as plasticizer. This could be explained by the increase in brittleness due to cross‐linking under the high temperature load during the extrusion process. Dynamic mechanical analysis of the films showed a substantial increase in storage modulus between 100°C and 200°C for CA‐containing starch–PVOH films. The contact angle of diiodomethane on the pre‐coating layer decreased when a plasticizer was added to the coating recipe indicating an increase in wetting of the PE melt. Addition of PEG to the pre‐coating led to a greater wetting than the addition of CA, and this may have sealed some defects in the pre‐coating leading to lower OTR values.
Prevalence of Depression and Associated Factors among Adults on Antiretroviral Therapy In Public Hospitals of Kembata Tembaro Zone, South Ethiopia

BackgroundCurrently, people living with Human Immunodeficiency Virus have longer life expectancies with the use of antiretroviral therapy. However; depression is the most common in these patients, which has markedly resulted to poor health outcomes due to reduced adherence to treatment and deterioration of medical outcomes, including treatment resistance, increase the demand for the utilization of medical resources and increase the morbidity and mortality. The aim of this study was to assess the prevalence and associated factors of depression among adult people living with HIV attending antiretroviral therapy clinic in public hospitals at KembataTembaro Zone, South Ethiopia,2020.MethodAn institution based cross sectional study was conducted in public Hospitals of KembataTembaro Zone from March 1/2020-April30/2020. Systematic random sampling technique was used to select the study participants. Data were collected using a pretested and structured questionnaire. Multivariable Logistic regression was performed to assess factors associated with depression using odds ratio at 95% confidence interval and P-value < 0.05. ResultsThe prevalence of depression was 44.3% (95% CI: 39.4% − 49.2 Being female (AOR = 2.03, 95% CI: 1.21,3.40), living alone (AOR = 3.09,95%CI :1.68,5.68), Having HIV related stigma (AOR = 2.85, 95% CI: 1.73, 4.71), poor social support (AOR = 2.55, 95% CI: 1.48, 4.78), CD4 count less than 350 cell/ul (AOR = 2.66, 95% CI: 1.48, 4.58) and Poor medication adherence (AOR = 2.19,95% CI: 1.32, 3.65) were factors significantly associated with depression.ConclusionThe prevalence of depression was high. Being female, living alone, having HIV related stigma, Poor social support, CD4 count less than 350 cell/ul and poor medication adherence were associated with depression. Depression should be included as part of the routine consultation of HIV patients to ensure early detection and treatment.
133Cs Nuclear Magnetic Resonance Relaxometry as a Probe of the Mobility of Cesium Cations Confined within Dense Clay Sediments

133Cs nuclear magnetic resonance is used to quantify the mobility of cesium counterions confined within the interlamellar space of synthetic Hectorite clay under controlled hydration conditions. The degree of lamellae ordering within the macroscopic clay sediment is determined by analyzing the variation of the 133Cs NMR spectra as a function of the sample orientation in the static magnetic field. Furthermore, a detailed analysis of the 133Cs NMR spectra allows one to determine the order of magnitude of the quadrupolar and heteronuclear dipolar couplings monitoring the NMR relaxation of the cesium cations confined within clay sediments. Finally, a lower limit to the average residence time of the cesium cations within the clay interlamellar space is determined by using 133Cs NMR relaxation measurements under spin-locking conditions.
Missing clinical trial data: the evidence gap in the safety of potential COVID-19 drugs

Background: Several drugs are being repurposed for the treatment of the coronavirus disease 2019 (COVID-19) pandemic based on in vitro or early clinical findings. As these drugs are being used in varied regimens and dosages, it is important to enable synthesis of existing safety data from clinical trials. However, availability of safety information is limited by a lack of timely reporting of clinical trial results on public registries or through academic publication. We aimed to analyse the evidence gap in safety data by quantifying the number of missing clinical trial results for drugs potentially being repurposed for COVID-19 by conducting a rapid review of results posting on ClinicalTrials.gov and in academic publications. Methods: ClinicalTrials.gov was searched for 19 drugs that have been identified as potential treatments for COVID-19. Relevant clinical trials for any prior indication were listed by identifier (NCT number) and checked for results and for timely result reporting (within 395 days of the primary completion date). Additionally, PubMed and Google Scholar were searched to identify publications of results not listed on the registry. A second, blinded search of 10% of trials was conducted to assess reviewer concordance. Results: Of 3754 completed trials, 1516 (40.4%) did not post results on ClinicalTrials.gov or in the academic literature. 1172 (31.2%) completed trials had tabular results on ClinicalTrials.gov. A further 1066 (28.4%) completed trials had results from the literature search, but did not report results on ClinicalTrials.gov. Key drugs missing clinical trial results include hydroxychloroquine (37.0% completed trials unreported), favipiravir (77.8%) and lopinavir (40.5%). Conclusions: There is an important evidence gap for the safety of drugs being repurposed for COVID-19. This uncertainty could cause a large burden of additional morbidity and mortality during the pandemic. We recommend caution in experimental drug use for non-severe disease and urge clinical trial sponsors to report missing results retrospectively.
Modified asphalt production from the hydrocarbon resin, SBS and LDPE

Modern highway transportation faces many challenges such as high traffic density, heavy load and high speed thus the asphalt pavements are founded to be subjected to various types of distress. That can be done by looking for good material to be added to the asphalt mix such as polymers LDPE, SBS and HR as shown by some researchers. The main objective of the work is to find new bitumen mix which is compatible with the Iraqi standard and saved the environment. The result indicates an improvement in most of the modified bitumen with HR, SBS and LDPE. 10% WCO, 88% bitumen and 2% HR give 60 mm Penetration, 99.3% solubility, 95 ductility, 44 C softening point and 288 flash point were seen to be optimum with the selected standard. At the end, the study indicates that a good quality bitumen can be achieved using HR, SBS and LDPE.
