Authors: Wang Jianjun , Zhu Xiaoyan , Wang Xiaoling , Li Xi 
Published: February 2022

Abstract

Objective: To explore the values of PCT and STREM-1 combined with clinical pulmonary infection score (CPIS) for evaluating ventilator-associated pneumonia (VAP) in elderly patients.

Methods: A total of 120 eligible patients were selected as VAP group, and 60 other patients without VAP were selected as control group. According to APACHE II scores, VAP group was divided into low-, medium-, and high-risk groups. The correlations of PCT, STREM-1, and CPIS with APACHE II score were analyzed. The values of PCT and STREM-1 combined with CPIS for evaluating prognosis were analyzed using ROC curves.

Results: In the VAP group, serum PCT and STREM-1 levels and CPIS after mechanical ventilation significantly exceeded those of the control group and before mechanical ventilation (P<0.05). These values were higher in the high-risk group than in medium- and low-risk groups (P<0.05). They were positively correlated with APACHE II score (P<0.001). These values of the death group were significantly higher than those of the survival group 1, 3, 5, and 7 d after treatment (P<0.05). AUC of PCT and STREM-1 combined with CPIS for assessing prognosis was 0.892 (P<0.001).

Conclusions: Serum PCT and STREM-1 levels and CPIS significantly increase in elderly patients with VAP, which rise with aggravation. Their combination has higher values for prognostic evaluation.
Expression of tight junction transmembrane protein Claudin-1 in gastric carcinoma and effects on tumor cell proliferation, invasion and migration
Authors: Lv Jun , She Zhuocui , Cai Ang 
Published: February 2022

Abstract

Background: Claudin-1 is involved in various cancers, but its expression and role in gastric carcinoma remain unclear.

Materials and Methods: Gastric carcinoma and adjacent normal tissues were harvested from 60 patients. Claudin-1 expression was detected by RT-qPCR. The expressions in human gastric carcinoma MKN45, SGC7901 and MKN28 cells and immortalized human gastric epithelium GES-1 cells were determined by RT-qPCR and Western blotting. Claudin-1 was overexpressed in SGC7901 cells by lentiviral transfection, and they were divided into Control (untransfected), normal control (NC) (transfected with lentiviral vector) and Claudin-1 (transfected with Claudin-1 overexpression lentivirus) groups. The proliferation, invasion and migration of gastric carcinoma cells were detected through cell counting kit-8, Transwell and wound healing assays, respectively. The effects of Claudin-1 on the expressions of epithelial-mesenchymal transition (EMT) marker proteins E-cadherin and N-cadherin were detected by Western blotting. Ten 4-week-old male BALB/c nude mice were subcutaneously injected with lentivirus-treated SGC7901 cells to establish the transplanted tumor model, and the effect of overexpression of Claudin-1 was explored.

Results: The expression of Claudin-1 in gastric carcinoma tissues was significantly lower than that in adjacent tissues (P<0.05). Overexpression of Claudin-1 significantly inhibited the proliferation, invasion and migration of SGC7901 cells, increased the expression of E-cadherin, and decreased that of N-cadherin (P<0.05). Overexpression of Claudin-1 in the mouse model significantly inhibited the growth of subcutaneous transplanted tumors (P<0.05).

Conclusion: Claudin-1 has low expression in gastric carcinoma tissues. Overexpression of Claudin-1 inhibits the proliferation, invasion, migration, and EMT of gastric carcinoma cells, and subcutaneous tumorigenesis in nude mice.

Published: February 2022

Abstract
Cataract represents the reduction of the transparency of the crystalline lens. Cataract surgery is the most commonly performed surgical procedure worldwide. One of the most common postoperative complication of successfully performed cataract surgery is a development of posterior capsule opacification (PCO). In the postoperative period, lens epithelial cells (LECs) undergo proliferation, migration and differentiation, which is clinically manifested by the development of PCO. Inflammation has a central role in these processes. Cytokines, such as transforming growth factor β, fibroblast growth factor, interleukin 1, interleukin 6, matrix metalloproteinases have a huge effect on the activity of LECs. Understanding these processes can find a great usage in clinical practice. By prescribing anti-inflammatory therapy in the early postoperative period, the incidence of PCO can be significantly reduced.
Performance Evaluation of the Fruit and Vegetable Subsectors in the Azerbaijani Economy: a Combinatorial Analysis Using Regression and Principal Component Analysis
Authors: Niftiyev Ibrahim 
Published: February 2022

Abstract
Azerbaijan has an oil-led economy, which according to the well-known resource curse and Dutch disease hypotheses decreases the role of non-oil tradable sectors. Nevertheless, the government has actively fostered the growth of non-oil tradable sectors as the export orientation of Azerbaijan is being leveraged by the recently adopted economic policies. However, performance evaluations at the subsectoral level remain rare. The present paper evaluates the performance of the fruit and vegetable subsectors in Azerbaijan from 1995 to 2020 based on multiple key indicators, such as production, profitability, and productivity via principle component analysis (PCA). The purpose of the study was to provide a comparison of two key subsectors in Azerbaijan that are strong candidates for non-oil tradable exports. The results revealed that the vegetable subsector outperformed the fruit subsector in terms of production and profitability from 1999 to 2014; however, it experienced a sharp decline from 2014 to 2015 (the period of the rapid commodity price downturns), which gives rise to the question of whether the extractive industry negatively affected the subsector. Compared to the vegetable subsector, production and profitability in the fruit subsector demonstrated a more stable upward trend. In addition, labor input in both sub-sectors decreased over time, indicating efficiency gains via new technology transfers and productivity enhancements. Ordinary Least Squares (OLS) results demonstrated a strong and statistically significant negative relationship between the performance of the vegetable subsector with the oil revenue boom period (2008–2015).
Are People Willing to Voluntarily Contribute to Public Goods? The Results from the Behavioral Game Experiment.
Authors: Sirakovová Eva , Čaplánová Anetta 
Published: February 2022

Abstract
In the paper, we discuss the possibilities of alternative provision of public goods using the individual voluntary contributions. We use the data from the behavioral public goods game based on the model of voluntary contribution mechanism. We examine how people’s decisions about voluntary contributions to public goods change when the environment changes. The participants of the game were divided into small (5 persons) and large (10 persons) groups. During the game participants were asked to invest experimental money to different types of accounts, i.e. private account, Group account 1 and Group account 2. Using the game, we also examine the impact of a provision point on voluntary contributions. Based on the analysis of the data from this behavioral game, we found that the provision point is effective only if the participants are members of a small group. When the participants were members of both a small group and of a large group the provision point was not effective. When the income of participants was considered, we found that participants with higher experimental income were less willing to voluntarily contribute to financing of a public good.
Work-Study-Life Balance – the Concept, its Dyads, Socio-Demographic Predictors and Emotional Consequences
Authors: Vokić Nina Pološki , Bilušić Milka Rimac , Perić Iva 
Published: February 2022

Abstract
The concept of working students meeting triple demands of their work, studies and private life has not been sufficiently described or empirically supported in the literature, although combining work and study is not only a necessity for many students, but a common phenomenon among them. As well, studies so far focused on the dyads of work-nonwork relationship, predominantly on the work-study conflict/balance and rarely on the study-life conflict/balance, while the triad of work-study-life balance (WSLB) is understudied. This study is the first one to empirically examine the WSLB concept, defined as a balance of conjoining three ‘categories of student commitment’ – their work obligations, demands of their studies and their private life, using a methodology grounded in the work-life balance (WLB) theory. We conducted a cross-sectional quantitative study on a sample of 235 students, focused on the most relevant dyads of the WSLB concept, socio-demographic predictors and emotional consequences of WSLB. Our five key findings are: (1) it is possible to balance work, studies and private life, (2) work-study balance (WSB) is critical for achieving WSLB, (3) all subgroups of students based on their socio-demographic characteristics are equally (un)successful in achieving balance between and among various life aspects, (4) WSLB is significantly participating in students’ emotional state in terms of their happiness, unhappiness and relaxation, and (5) the study-life balance (SLB) dyad is the most relevant dyad for the students’ emotional state.

Authors: Al-Rubaie Sundus Khudair , Abdulhay Hind Suhail 
Published: February 2022

Bioethanol is an attractive fuel with higher potential for energy security and environmental safety. Olive solid residues were used as a raw material for the production of bioethanol through the use of different preliminary treatments . Separate treatments with cellulose, hydrochloric acid (HCl 5%), sulfuric acid (H2SO4 2%), and liquid ammonia NH4OH (20%) were used to convert cellulose and hemicellulose into monosaccharaides. The production of ethanol was observed during the fermentation process using R. minuta under anaerobic conditions. After 3 days of fermentation, lowest concentrations of ethanol of 0.233, 0.249, 0.261, and 0.275 g/ l were produced from olive waste powder sample as a result of separate pretreatment with cellulase, hydrochloric acid (HCl 5%), sulfuric acid (H2SO4 2%), and liquid ammonia NH4OH (20%), respectively, whereas the untreated sample showed ethanol yield of 0.264 g/ l.. The highest ethanol concentrations for the same samples were 0.510, 0.564, 0.737, and 0.696 g/ l, respectively, whereas that for the untreated samples was 0.445 g/ l. The highest concentration of ethanol produced (0.737 g/ l) was achieved after 3 days of fermentation of olive solid waste pretreated with H2SO4 2% at 30 oC and pH 5. The average yield of ethanol resulted from these saccharification and fermentation processes following the pretreatment of olive solid waste was 0.59 g/10 g dry olive solid residues.

Published: February 2022

Anthropometri adalah bagian dari ergonomi yang mempelajari dimensi tubuh manusia. Dalam perkembangannya saat ini, Anthropometri masih kesulitan dalam melakukan proses pengukuran terutama untuk mengukur gerakan tubuh manusia (Anthropometri Dinamis), yang disebabkan oleh keterbatasan alat ukur yang ada.
Software Motion Capture merupakan salah satu alat ukur Anthropometri Dinamis terlengkap yang penulis ketahui sampai saat ini. Tapi karena harganya yang mahal yaitu & Rp. 1 Milyar (Karya Agung - Technical Supplier and Education Supporter, tahun 2006) maka tidak setiap Universitas dapat memilikinya. Sedangkan alternatif lain yaitu dengan menggunakan alat ukur Anthropometri Dinamis secara manual pun yang ada saat ini masih terbatas hanya dapat mengukur 2 variabel Anthropometri Dinamis dari 21 Variabel. Berdasarkan kondisi diatas maka diperlukan perancangan alat ukur Anthropometri Dinamis manual sebagai alternatif lain.
Berdasarkan hasil identifikasi kebutuhan didapatkan karakteristik alat ukur anthropometri dinamis yang diinginkan yaitu yang valid, handal, multifungsi, aman, nyaman, mudah digunakan, tahan lama, portable serta harganya murah. Dan karena keterbatasan waktu dan keterbatasan pengetahuan penulis, maka alat ukur yang dirancang dalam penelitian ini hanya dapat mengukur 6 variabel Anthropometri Dinamis yang dikelompokan pada sendi leher sebanyak 3 variabel dan pergelangan tangan sebanyak 3 variabel.

Peralatan spray driver belum begitu luas penggunaannya di dalam industri keramik. Hanya ada dua contoh yang ingin dikemukakan, itupun hanya berkaitan dengan bahan baku pembuatan keramik, yaitu alumina dan pewarnaan keramik (ceramics colors). Makalah ini ingin menyajikan sedikit teori, karakteristik operasi dan contoh rancangan alat sederhana serta perkembangan pemakainya pada industri di Indonesia.
Spray Drying adalah pengeringan larutan dan bubur (slurries) dengan cara mendispersikan larutan, dalam bentuk tetesan (â€œ "â€œF' ke dalam aliran panas. Ada tiga proses dasar yang akan menentukan sukses tidaknya pengeringan, yakni atomisasi cairan, pencampuran antara gas dengan tetesan cairan, dan pengeringan cairan. Selain itu, dalam metoda perancangan ketiga peristiwa di atas, tergantung pada:

Bentuk dan ukuran partikel yangdiinginkan.
Sifat fisik umpan.
Temperatur maksimum yang bisa dicapaioleh gas-masukan (inlet-gas) dantemperatur produk.

Sampai saat ini pelaratan pengering jenis ini masih banyak diimpor. Problema utama untuk menguasai ilmu dan rekayasa terletak pada teknologi atomisasi (pendispersian) larutan sesuai dengan diameter partikel produk yang diinginkan dan pendistribusian gas-masukannya.
