Abstract
Urea formaldehyde (UF) resins are brittle and to improve their tensile properties poly(vinyl alcohol) (PVA) has been used to modify the UF resin. An easy improved procedure was developed to make PVA modified UF resin on the basis of conventional synthesis of UF resin. Prepolymer of UF was mixed with different weight percentages of PVA (1-5%) to synthesize modified UF resin which can be used to make adhesive for forest products. Both UF and modified UF resins were characterized by FTIR, physico-mechanical and thermal properties analyses. Modified UF resin containing 2 wt. % PVA exhibited better results than the UF.

Published: January 2022

Abstract
This study examined the effect of induction heating on the microstructure and corrosion characteristics of hybrid friction stir welded AISI 410 stainless steel. Five joints have been produced with different friction stir welding parameters like welding speed, spindle speed, plunge depth, and induction power. Their microstructures were evaluated using a scanning electron microscope, and chemical composition was examined using energy-dispersive X-ray spectroscopy (EDX). The rate of corrosion was found out via the weight loss method in a 1 M HCL solution. The hybrid friction stir welding method used for this work is induction assisted friction stir welding; the results show that this method could produce sound AISI 410 stainless steel Joints. The experiment results show that the joint made at a spindle speed of 1150 rpm, welding speed 40 mm/min, plunge depth 0.5 mm, and in-situ heat by induction 480°C show a better corrosion resistance property with a fine grain structure.

Published: January 2022

Abstract
Alloys of FeNiSiB soft magnetic materials containing variable Fe and Ni contents (wt.%) have been produced by melt spinning method, a kind of rapid solidification technique. The magnetic and structural properties of FeNiSiB alloys with soft magnetic properties were investigated by increasing the Fe ratio. X-ray diffraction analysis and SEM images shows that the produced alloy ribbons generally have an amorphous structure, together with also partially nanocrystalline regions. It was observed that the structure became much more amorphous together with increasing Fe content in the composition. Among the alloy ribbons, the highest saturation magnetization was obtained as 0.6 emu/g in the specimen with 50 wt.% Fe. In addition, the highest Curie temperature was observed in the sample containing 46 wt.% Fe.

Published: January 2022

AbstractPurposeThis study deals with missions, significant policies, operational approaches, and training programs learned from Singapore's experiences, thus contributing to a more profound knowledge of entrepreneurship in order to establish suggestions and boost the implementation of entrepreneurship and incubator business, particularly in universities in Indonesia. This study purposes to understand in-depth the practical implementation approaches of university incubation centres to facilitate entrepreneurship in Singapore. Insights were obtaining following a literature review approach.Design/methodology/approachData for this study were collected from a variety of sources, including government documents, university reports, global related entrepreneurship research websites (GEI, Global Entrepreneurship Monitor [GEM], 2019), and related journals (e.g., Entrepreneurship, Incubators, and University Incubators).FindingsSynthetically, incubation centres possess the following primary missions: (1) they integrate professionals in various fields to promote industry partnerships and engagement; (2) they provide training to new entrepreneurs for achievement enhancement, mainly to help them acquire missing business knowledge; (3) they encourage start-ups to engage with one another in the culture of incubators, to enlist more people to join in supporting and expanding the society; (4) they commercialise intellectual properties and promote the commercialisation of inventions and innovations for the future market; (5) they bridge academic professors with industry entrepreneurs for technology upgrades and business transformation. To summarise, University Incubation Centres in Indonesia should strive to emulate the best practices of some Singaporean universities and do everything possible to help their tenants accelerate their entrepreneurial processes. In order to be competitive, an incubator must extend its network and partner with successful industries, funding agencies, industries, and universities.

Abstract
Apart from currently available therapeutics for the treatment of diabetes mellitus, much attention has been paid to discover phytochemicals from natural resources, mainly due to their low side-effects. Hypericum perforatum hairy root (HR) transformed with Agrobacterium rhizogenes A4 represent prospective experimental system enriched in xanthones, known as potent antidiabetic agents. Thus, the aim of this study was to evaluate HR extracts for their potential antihyperglycemic activity in streptozotocin (STZ)-induced diabetic rats, also compared to the effects of wild-growing Hyperici herba (HH). We conducted an acute-toxicity study, multiple dose study, and 24h blood glucose measurements after a single dose administration of HH and HR (200 mg/kg) in diabetic rats. Furthermore, we examined the effects of 14-days administration of HH and HR extracts on blood glucose levels, metabolic parameters, enzyme, and lipid status in healthy and diabetic rats. Both extracts produced a fall of about 70% in blood glucose level after 24h of administration. Two-week treatment with HH and HR induced a significant decrease (70-72%) in blood glucose levels. Moreover, we found an improvement of the dysregulated metabolic parameters (body weight, food, and water consumption and urine output). Serum enzyme (AST, ALT, and γ-GT) and lipid profile parameters (CHOL, TAG, and HDL) were also improved by both extracts. These findings might provide a new insight for managing diabetic hyperglycemia and dysregulated serum enzyme and lipid profile, using extracts from transgenic roots cultures from H. perforatum.
The influence of post-deformation annealing temperature on the mechanical properties of low-carbon ferritic steel deformed by the DRECE method
Authors: Kowalczyk Karolina 
Published: January 2022

Abstract
The paper presents observations on the mechanical properties characterizing low-carbon steel subjected to deformation by the dual rolls equal channel extrusion (DRECE) method and annealed for 60 min in different temperature variants in the range of 450–700°C. The DRECE process was carried out up to seven passes at ambient temperature. The investigations carried out revealed that the strength of the steel strips increases corresponding to the rise in the number of DRECE passes applied. The yield strength (YS) after seven passes is >2.5 times higher compared to the material in the initial state (before the deformation process). However, the tensile ductility decreased significantly after the DRECE. In order to obtain favorable mechanical properties, the steel strips were subjected to annealing. Our study demonstrates that after being processed by the DRECE method, low-carbon steel can be subjected to low-temperature annealing to ensure that it is endowed with high strength, while maintaining the characteristic good ductility of the material. The results of the research were analyzed in the context of an investigation into the microstructure change, assessed by scanning transmission electron microscopy (STEM), induced in low-carbon steel subjected to the DRECE process and low-temperature annealing.
Influence of flame straightening on the properties of welded joints made of X2CrNi22-2 duplex steel
Authors: Lange Artur 
Published: January 2022

Abstract
The study investigates the optimal conditions associated with flame straightening of welded joints in duplex steel grade X2CrNi22-2. The research aimed to assess the influence of heat, applied during flame straightening of welded structures in X2CrNi22-2 grade steel, on the properties of the welded joints. Based on the macroscopic, microscopic, and strength tests conducted on welding joints in X2CrNiN22-2-grade duplex steel that have been subjected to flame straightening, it was ascertained that post-welding flame straightening of this grade of steel, at a treatment temperature of 730°C, should not take place for >1 min. The temperature of 730°C has been chosen as a reference because of the assumption that the welded joints are heated to the temperature of 700–730°C during straightening with an acetylene-oxygen flame. The paper scrutinizes the questions of (i) what changes occur in the welded joints as a result of flame straightening carried out in this temperature range and (ii) what impact those changes have on the joint strength. The results of our study indicate that the duration of post-welding flame straightening of X2CrNiN22-2-grade duplex steel, at a treatment temperature of 730°C, should not exceed 1 min.

Authors: Li Chengshuai , Ma Wencheng 
Published: January 2022

Abstract
New extractive distillation configurations, which use low transition temperature mixtures (LTTMs) as entrainers, have attracted widespread attention among scholars due to their green processes. Furthermore, the design and comparison of different processes can promote the application of new solvents in the future. In this study, two extractive distillation processes, the extractive distillation column (ED) and the extraction dividing wall column (EDW), were selected from previous work. The separation process of acetonitrile (ACN)-water ternary mixtures was studied, and GC3:1(choline chloride/glycolic acid mixture (molar mass 1:3)) and EC2:1((choline chloride/ethylene glycol 1:2 molar mass) were used as entrainers. Minimum consumption energy and the purity of ACN and water were set as the goals, and our sensitivity analysis and economic evaluation results showed that both ED and EDW were effective. As a result, LTTMs can be used in extractive distillation for azeotrope separation.

Published: January 2022

Background: Acute pancreatitis (AP) is an inflammation of the pancreas, a serious emergency with no definitive treatment. It may progress to infected necrosis, non-pancreatitis infection, also death that may occur within the first 1 to 2 weeks. The use of prophylactic antibiotics in AP to prevent complications remains a controversy. The objective of this meta-analysis is to assess the benefit of prophylaxis antibiotics administration to prevent the complication.Method: Trials were identified by searching the medical database. Literature range is within the year 1975 to 2021. Review Manager 5.4.1 was used to analyse data extraction and risk of bias of included studies were elaborated. Risk ratio (RR) was calculated with 95% confidence interval (CI). P 0.05 was considered significant.Results: Twenty trials with a total of 1.287 patients of AP were analysed; 646 patients treated with antibiotic prophylaxis and 641 patients treated with placebo. Prophylaxis antibiotics were found to have significant difference between the two groups. The administration of prophylaxis antibiotics lower the risk of non-pancreatic infections (RR = 0.77; 95% CI: 0.62–0.95; p 0.05) and infected pancreatic necrosis (RR = 0.74; 95% CI: 0.58-0.94; p 0.05). Meanwhile, prophylaxis antibiotics were found to be insignificant to lower the risk of mortality (RR = 0.75; 95% CI: 0.54-1.03; p 0.05). Conclusion: Prophylaxis antibiotics lower the risk of non-pancreatic infections and infected pancreatic necrosis, but did not lower the risk of mortality.

Non-cirrhotic portal hypertension (NCPH) is a heterogeneous group of liver disorders leading to portal hypertension. There are multiple approaches to managing portal hypertension' clinical complications to treat/prevent spontaneous hemorrhage by mitigating thrombocytopenia. Portal hypertension complications have been traditionally managed with serial endoscopic variceal ligation (EVL) or with invasive open surgical procedures such as orthotopic liver transplantation (OLT) or portosystemic shunting, splenectomy.6–9 There are several risks associated with splenectomies, such as hemorrhagic complications or intraoperative blood loss.5,6,14 Partial Spleen Embolization (PSE) ‎may overcome the limitations of splenectomy and provide patients with an alternative treatment. An eighteen-year-old male has a splenomegaly history since he was 12 years old and has recurring hematemesis and melena. After performing abdominal computed tomography, laboratory studies, and several endoscopies, the results indicated secondary hypersplenism due to non-cirrhotic portal hypertension. The patient had 13 endoscopies and 2 EVL in 5 years. Despite adequate treatment, the patients developed recurrent variceal bleeding and no improvement in blood function. The patient underwent PSE at Integrated Cardiovascular Center in Dr. Cipto Mangunkusumo, General Hospital, Jakarta, Indonesia. It was performed through the femoral access with a PVA (polyvinyl alcohol) embolus. The procedure went successful, and there was no major complication with the patient. Twenty days after the patient had an abdominal CT scan, it showed no abscess, and the spleen volume was reduced by 20%. Long-term results over a year after the procedure are presented. PSE is a safe, effective, semi-invasive alternative to splenectomy in non-cirrhotic portal hypertension because it preserves functional spleen mass and avoids postprocedure accelerated liver disease or encephalopathy.

<p>Religion functions are to build brotherhood, yet religions can also be a source of <br />conflict.The rejection of Piodalan Ritual carried out by Maha Lingga Padma Buwana<br />Community by a number of Mangir Lor Sub-village residents, is a socio-religious conflict. The research aims to find out and explain why there is the rejection of Piodalan Ritual, and how the government together with the community resolve the conflict. The research uses a case study approach. Data collection techniques include interviews, observations, documentation, and triangulations. Primary data sources are from structural officials of government and cultural leaders of the community. Secondary data sources are from documents, reference books, and historical records. Analysis of qualitative data in interactive and continuous manners includes data reductions, data presentations, and conclusions. The result shows that the conflict between Mangir residents and Mahalingga Padma Buwana Community is the lack of communication and different perceptions regarding the Piodalan Ritual. The government and the community resolve the conflict by utilizing the local wisdom values, rembuk desa (deliberation), rukun (harmony), and ngajeni (respect).</p><p> </p>
A review of COVID-19 transmission dynamics and clinical outcomes on cruise ships worldwide, January to October 2020
Authors: Willebrand Kathryn S , Pischel Lauren , Malik Amyn A , Jenness Samuel M , Omer Saad B 
Published: January 2022

Background
Cruise ships provide an ideal setting for transmission of SARS-CoV-2, given the socially dense exposure environment.

Aim
To provide a comprehensive review of COVID-19 outbreaks on cruise ships.

Methods
PubMed was searched for COVID-19 cases associated with cruise ships between January and October 2020. A list of cruise ships with COVID-19 was cross-referenced with the United States Centers for Disease Control and Prevention’s list of cruise ships associated with a COVID-19 case within 14 days of disembarkation. News articles were also searched for epidemiological information. Narratives of COVID-19 outbreaks on ships with over 100 cases are presented.

Results
Seventy-nine ships and 104 unique voyages were associated with COVID-19 cases before 1 October 2020. Nineteen ships had more than one voyage with a case of COVID-19. The median number of cases per ship was three (interquartile range (IQR): 1–17.8), with two notable outliers: the Diamond Princess and the Ruby Princess, which had 712 and 907 cases, respectively. The median attack rate for COVID-19 was 0.2% (IQR: 0.03–1.5), although this distribution was right-skewed with a mean attack rate of 3.7%; 25.9% (27/104) of voyages had at least one COVID-19-associated death. Outbreaks involving only crew occurred later than outbreaks involving guests and crew.

Conclusions
In the absence of mitigation measures, COVID-19 can spread easily on cruise ships in a susceptible population because of the confined space and high-density contact networks. This environment can create superspreader events and facilitate international spread.
