Perceptions and Sentiments About Electronic Cigarettes on Social Media Platforms: Systematic Review
Authors: Kwon Misol , Park Eunhee 
Published: September 2019

Background
Electronic cigarettes (e-cigarettes) have been widely promoted on the internet, and subsequently, social media has been used as an important informative platform by e-cigarette users. Beliefs and knowledge expressed on social media platforms have largely influenced e-cigarette uptake, the decision to switch from conventional smoking to e-cigarette smoking, and positive and negative connotations associated with e-cigarettes. Despite this, there is a gap in our knowledge of people’s perceptions and sentiments on e-cigarettes as depicted on social media platforms.

Objective
This study aimed to (1) provide an overview of studies examining the perceptions and sentiments associated with e-cigarettes on social media platforms and online discussion forums, (2) explore people’s perceptions of e-cigarette therein, and (3) examine the methodological limitations and gaps of the included studies.

Methods
Searches in major electronic databases, including PubMed, Cumulative Index of Nursing and Allied Health Literature, EMBASE, Web of Science, and Communication and Mass Media Complete, were conducted using the following search terms: “electronic cigarette,” “electronic vaporizer,” “electronic nicotine,” and “electronic nicotine delivery systems” combined with “internet,” “social media,” and “internet use.” The studies were selected if they examined participants’ perceptions and sentiments of e-cigarettes on online forums or social media platforms during the 2007-2017 period.

Results
A total of 21 articles were included. A total of 20 different social media platforms and online discussion forums were identified. A real-time snapshot and characteristics of sentiments, personal experience, and perceptions toward e-cigarettes on social media platforms and online forums were identified. Common topics regarding e-cigarettes included positive and negative health effects, testimony by current users, potential risks, benefits, regulations associated with e-cigarettes, and attitude toward them as smoking cessation aids.

Conclusions
Although perceptions among social media users were mixed, there were more positive sentiments expressed than negative ones. This study particularly adds to our understanding of current trends in the popularity of and attitude toward e-cigarettes among social media users. In addition, this study identified conflicting perceptions about e-cigarettes among social media users. This suggests that accurate and up-to-date information on the benefits and risks of e-cigarettes needs to be disseminated to current and potential e-cigarette users via social media platforms, which can serve as important educational channels. Future research can explore the efficacy of social media–based interventions that deliver appropriate information (eg, general facts, benefits, and risks) about e-cigarettes.

Abstract

Objective: The purpose of this study was to investigate the benefits of two different Selenium based supplements on patients with chronic autoimmune thyroiditis.

Methods: We conducted a prospective study on 50 patients with chronic autoimmune thyroiditis, who were divided into three different treatment groups, one group taking Selenium 100 μg, one Procor T (a combination of Selenium 100 μg and other elements like copper, Zinc and Q10 Conenzyme) and one control group taking Placebo pills. We measured on two follow up visits the antibody levels (anti-thyroidperoxidase- TPO Ab) and offered each patient a standardised questionnaire regarding the thyroid-related quality of life (THYPROro).

Results: At the 6 months follow up visit there was a statistically significant decrease in the antibody levels for each treatment group compared to the base levels. The THYPROro questionnaire scores showed an improvement in most aspects regarding the quality of life as well, but there was no significant difference between the placebo and the treated groups in the magnitude of this improvement.

Conclusions: Based on our results, we could not identify a certain benefit in improving quality of life with the supplementation of Selenium, as the improvements were at a similar level for the patients who took Placebo pills. Further studies with more patients, as well as taking the Selenium defficiency in consideration (by measuring the basal serum level of Selenium for each patient) would be required to find the target group of patients who could have most benefits of Selenium-based supplementation.

Published: September 2019

Abstract
Surgery associated with lymphadenectomy may sometimes result in a lymphorrhagia, which usually resolves spontaneously within a few days, sometimes becoming a refractory complication to the treatment. In the case of large flows, particular attention should be paid to hydro-electrolytic and protein losses. We present the case of a patient with persistent lymphorrhagia after a cephalic duodenopancreatectomy for a pancreatic head tumor. From the 5th postoperative day, the patient had a milky-like secretion on the subhepatic drainage tube. The discharge rate was variable, between 500 and 1500 ml per day, requiring parenteral administration of amino acids, plasma and electrolyte solutions. The postoperative progression was slowly favorable, with the patient discharge on the 25th day following surgery. There are several treatment options for a lymphorrhagia following an extended lymphadenectomy, from intensive parenteral therapy to peritoneal-venous shunt or ligation of the lymphatic vessel responsible for the production of lymphorrhagia. In this case the conservative treatment had a favorable result.
Funding Modalities for Timber Housing in Brazil

Published: September 2019

Abstract
This paper investigated the existence and participation of public and private real estate credit lines for timber house funding in Brazil. The analysis was completed through face-to-face interviews with Brazilian timber housing producers. Semi-structured questionnaires were applied in this survey method to obtain a sectorial approach of the industry. Accesses to full financing for timber housing and credit for the acquisition of construction materials were the main two issues studied. About 107 producers were fully evaluated from all sectors. Half of the studied companies offer full housing finance and, simultaneously, most loans still come from private banks. Credit directed to raw materials emerges as the most common method of accessing funding for timber-based construction despite the lower economic value of this form of credit compared to other, more complete financial options. Public banks disseminate partial credit more frequently because of lower rates and lower restrictions, such as the absence of insurance requirements against risks from these construction ventures. Full funding proliferation will stimulate this market.
On some products in pro-categories and shape categories
Authors: Pop I. 
Published: September 2019

Abstract
This paper has two parts. In the first part we present a case in which we can calculate in a simple way the product of two inverse systems as object in a pro-category of a category with directed products, without counting systems at the same set of indices. In the second part, which is related to some papers of Keesling [4], Kodama [5], Mardešić [7], and Dydak-Mardešić [10], we give a sufficient condition by which a directed product of a category 𝒯 is transformed by a shape functor S : 𝒯 → Sh(𝒯, 𝒫) into a directed product. This theorem is applied to the toplogical shape category Sh(Top) where some examples are obtained.
Enhanced Evolutionary Computing Assisted Robust SLA-Centric Load Balancing System for Mega Cloud Data Centers
Authors: Govardhan P. , Srinivasan P. 
Published: September 2019

Abstract
Considering significance of a robust and Quality of Service (QoS) centric cloud computing, virtualization assisted load-balancing has been found a potential solution. However, assuring optimal Virtual-Machine (VM) migration with minimum violation of Service-Level-Agreement (SLA) and QoS degradation has been the challenge for academia-industries. VM allocation or scheduling being an NP-hard problem has been solved by numerous heuristic approaches such as classical Genetic Algorithm (GA), Ant Colony Optimization (ACO), etc. However they have been found confined due to local minima and convergence issues, especially for Mega Data Centres (MDCs). To alleviate such issues, in this paper an enhanced Evolutionary Computing algorithm named Adaptive Re-sampling GA (ARGA) algorithm has been developed that in conjunction with a stochastic prediction based dynamic load–measurement and Maximum Correlation (MC) assisted VM selection perform optimal load balancing over IaaS MDC infrastructures. The proposed ARGA VM allocation model with dual-level dynamic threshold assisted load estimation and MC based VM selection has exhibited lower SLA violation, performance degradation, downtime and minimum VM migration as compared to classical ACO based load balancing.

Published: September 2019

Abstract
In this paper, Cd0.3Zn0.7S thin film has been electrodeposited from aqueous bath containing CdSO4, ZnSO4, Na2S2O3 and EDTA, having pH ~ 14. The structural, optical, morphological, surface wettability and photoluminescence properties of the film were investigated. The XRD pattern showed that the film consisted of mixed phases of CdS and ZnS with polycrystalline structure. The bandgap of the film was evaluated as 2.69 eV. The AFM study revealed that the Cd0.3Zn0.7S thin film contained spherical grains with root mean square roughness of 6.09 nm. The water contact angle measurement showed that the thin film was hydrophilic in nature. Moreover, the PL study revealed that the excitation wavelength was 460 nm.

Abstract
Enzymatic preparation from culture of keratinolytic Bacillus cereus PCM 2849 was applied for hydrolysis of whole chicken feathers, after sulphitolytic pretreatment. This process was optimized using a three-factor Box-Behnken design, where the effect of substrate concentration, sulphite concentration during pretreatment and reaction temperature was evaluated on the release of amino acids. Obtained results revealed the highest impact of reaction temperature, followed by substrate content and sulphite during pretreatment. Optimal process conditions were established, i.e. temperature 44.4°C, feathers 4.7% and treatment with 25.3 mM sulphite. Amino acid composition of the obtained hydrolysate was analyzed. Glutamic acid (9.21 g·kg−1) and proline were dominant, however significant amount of branched-chain amino acids was also observed. The FTIR analysis of residual substrate revealed the cleavage of disulphide bonds in keratin through the presence of thioester residues. The absence of reduced cysteine residues was confirmed, along with minor changes in proportions of keratin substructures.

Instituições Experimentais de Arte na Europa nos anos noventa e dois mil
Authors: Marziale Nicole Palucci 
Published: September 2019

Este artigo propõe uma contextualização acerca de propostas realizadas em museus e centros de arte, a partir dos anos 1990, principalmente no âmbito europeu, para promover programas experimentais dentro de seus contextos institucionais. Tais propostas surgem em decorrência de ou como resposta a acontecimentos como: a gradual transformação das estruturas museológicas tradicionais em direção à possibilidade de emergência de novos modelos; a internalização das propostas de duas gerações de artistas engajados com a Crítica Institucional, que levaram à constituição de Instituições de Crítica; o surgimento da figura do curador independente; a reação dessas instituições diante da crescente influência do capitalismo globalizado e corporativo sobre a dinâmica das instituições de arte. É abordado, como exemplo de instituição experimental, o caso do basis voor actuele kunst (BAK). Observa-se, ainda, como muitas dessas experiências sofreram alterações como cortes orçamentários, mudanças de direcionamento político e substituição de diretores, o que levou diversos autores a indagar acerca da possibilidade de continuidade dessas experimentações institucionais.
