Abstract

Bacillus megaterium is a spore forming bacteria that is mostly used as a probiotic in aquaculture. Spore formation for probiotic production using carbon source is costly. This research evaluated the effect of different carbon doses of tapioca (Manihot esculenta) flour on vegetative cells, spore production, sporulation efficiency and spore germination of B. megaterium. Experiments were carried out in Aquaculture Laboratory, University of Brawijaya. In flasks, 50 ml of growth media were used and were inoculated with 1% of B. megaterium (2.6 x 108 cells/ml). The cultures were mixed (120 rpm) and incubated at 37 °C for 120 hours with 4 different treatments of carbon doses (5, 10, 15 and 20 g/L, respectively). The results showed that the highest vegetative cells (8.4 x 107 cell/ml) and spore production (4.1 x 107 spore/ml) of B. megaterium were found at 15 g/L carbon dose. However, it was not followed by high sporulation efficiency (only 49.01%). The high spore germination was observed in more than 5 g/L carbon dose. Thus, 5-15 g/L carbon doses of tapioca flour could positively enhance vegetative cells, spore production, sporulation efficiency and spore germination of B. megaterium and could be used as a potential source of probiotics in aquaculture.

Published: February 2020

Abstract
This study was aimed to observe the effect of cryopreservation on gastrula-staged embryo of African catfish. The gastrula-staged embryos were treated 5% (v/v) solutions concentration of dimethyl sulfoxide, propylene glycol, honey, and combined cryoprotectants, respectively and preserved at temperatures of -4 and -196ºC (in liquid nitrogen) for 30 min, 1 h, 2 h, 3 h, 4 h, 5 h, and 6 h, respectively. Thawing of embryos was conducted in freshwater at temperature of 28ºC. After thawing, the embryos were incubated in the aquaria at 28ºC temperature. The result showed that the cryopreservation of gastrula-staged embryo at temperatures of -4 and -196ºC affects damage and hatching percentages of African catfish embryos. The percentage of catfish embryo damage increases with the length of preservation at temperature of -4ºC for all treatments. A combination of DMSO+honey and PG+honey has the lowest damage percentage and the highest hatching rate of catfish embryo compared to other treatments (p<0.05). Meanwhile, total embryo damage occurs since the first 30 min of preservation at temperature of -196ºC for all treatments. Cryoprotectant toxicity and inability to protect the embryo are thought to be a cause of damage and death of catfish embryos on preservation, especially at temperature of -196ºC.

Published: February 2020

Abstract
Fishery-based lobster production decreased substantially due to over-exploitation and urge fishermen to catch smaller-size. In early 2015, the Ministry of Marine Affairs and Fisheries restrained catch of species up to 8 cm carapace length or at least 200 g weight. This study to identify species and individual size within catch of two different fishing gears at different fishing ground. “Krendet”, demersal pot (trap) was operated from the cliff of strong reef crest that connected to land-coast with a strong rope. Outside the cliff, fishermen operated gill net. Catch species were identified based on morphology and meristic. Species composition was calculated based on number of each species within catch. The results showed that there were six species was catch: Panulirus penicillatus, P. homarus, P. longipes, P. ornatus, P. versicolor, and P. polyphagus. It represents all lobster species of Indonesia. P. homarus dominated the catch at fishing ground outside the pinnacle (63%), and near cliff species was dominated by P. penicillatus (69%). Regarding size regulation, only 42% of catch met the carapace length of > 8 cm. Carapace length-weight relationship does not always meet the criteria. These results indicated that part of lobster fishery were exploited undersize exposing the stock under risk.

Abstract
This study aimed to screen probiotic candidates for the capacity to degrade ammonia content in the manure of laying hens. Seven bacteria previously isolated from broilers’ intestine were assigned to a completely randomized design. A fresh culture of each bacterial isolate was cultured to reach optical density at OD600:0.5. One ml suspension was inoculated into 100 ml samples (2g manure diluted in 100 ml of sterilized distilled water) and incubated for three days. Ammonia concentrations in each sample were measured daily using Ammonium/Ammonia-Test sera ammonia kits. The results showed that the ammonia concentration in all bacteria-treated samples was significantly lower than ammonia content in control, P<0.05). The average amount of ammonia in the control was 1.00±0.44 mg/l, while isolate I1-treated sample was 0.03±0.00 mg/l, isolate I2 0.02±0.00 mg/l, isolate I3 0.02±0.00 mg/l, isolate I4 0.04±0.01 mg/l, isolate I5 0.04±0.01 mg/l, isolate I6 0.02±0.01 mg/l and isolate I7 0.05±0.00 mg/l. The best three ammonia degrading capacity among the seven isolates were I2, I3, and I6. Based on the phenotypical characteristics, these bacteria were identified as Nitrosomonas sp. (I2), Nitrosobolus sp. (I3), and Nitrosococcus sp. (I6). Therefore, these three bacteria were recommended for probiotic candidates in laying hen.

Published: February 2020

Abstract
Hypertension is the most prevalent non-communicable disease in Indonesia. Stress is one of the modifiable risk factors of hypertension. Work stress is a complaint or disorder of physical, psychological, or social conditions, related to work and can be experienced by workers. This study was aimed to investigate the correlation between work stress and hypertension among industrial workers. A cross-sectional study in 100 male workers in the production department of a manufacturing industry in Bekasi, Indonesia, was conducted. The measurement of work stress was obtained by Work Stress Questionnaire (WSQ) and categorized as workers with work stress and without work stress. Hypertension was defined according to 2018 ESC/ESH Guidelines for the management of arterial hypertension. The relationship of variables was analyzed by chi-square test and stated as prevalence ratio (PR). The confounder of age was adjusted using logistic regression. The prevalence of hypertension was significantly higher in workers with work stress, PR = 5.58, 95% CI 1.54–20.23 (p=0.005). Adjusted PR after adjusting for age was 6.27, 95% CI 1.71–23.06 (p=0.006). In conclusion, there is a significant correlation between work stress and hypertension among industrial workers.

Published: February 2020

Abstract
The reduced number and function of Endothelial Progenitor Cells (EPC) in stable coronary artery disease (SCAD) patients aggravate endothelial dysfunction and inhibit neovascularization, thus leading to atherosclerosis. Garlic is currently believed to increase the number and function of EPCs. Therefore, this in vitro study was conducted to analyse the effect of garlic extract (Allicin) on the proliferation of EPCs in patients with SCAD. Mononuclear cells were isolated from peripheral blood of eight SCAD patients and cultured on CFU-Hill media for three days. Samples were divided into 2 groups: a group treated with Allicin and a control group. The treatment group was then divided into 3 subgroups which received 10, 50, and 100 mg/ml of doses and incubated for 48 hours. EPC proliferation was assessed using MTT Cell Proliferation Assay. Immunohistochemical method of CD34+ were performed for EPC identification. Data was analysed using an independent T test and ANOVA. MTT Assay showed significant increase in EPC proliferation in Allicin group compared to control group (0.2811±0.008 vs 0.194±0.151, p<0.05) and significant improvements were observed in each dose increment. CFU-Hill quantification shows the addition of EPC colony in high-dose Allicin. Immunohistochemical method shows positive CD34+ expression. Allicin increases EPC proliferation dose-dependently from peripheral blood of SCAD patients.

Published: February 2020

Abstract
Coronary heart disease (CHD) causes high mortality and morbidity in many countries. Immature platelet reactivity is one of the major causes of CHD thrombus formation due to its larger size and stronger aggregation properties than normal platelets. Though still controversial, diabetes mellitus (DM), which is one of the CHD risk factors, is mentioned to have a strong association with a high immature platelet level. Since studies on immature platelet in stable CHD are limited, the authors intended to search for the difference between immature platelet level in DM and non-DM patients with stable CHD. This research was an observational analytic study with a cross-sectional design; 31 samples of CHD patients who underwent coronary catheterization were obtained. The characteristics of the data was collected by completing a pre-operation form and the immature platelets were counted using an automated cytometry tool, SYSMEX XE 2100. They were analyzed using Pearson’s statistical analysis. There was no significant correlation between the immature platelet levels of DM and non-DM patients with stable CHD (p>0.05). There was a significant positive correlation between HbA1C and the immature platelet level (Immature Platelet Fraction, p <0.05; Immature Platelet Count, p <0.01) in stable CHD patients.

Published: February 2020

Abstract
The aim of this study is to investigate the effect of black tea administration on serum adiponectin level in male Wistar fed with atherogenic diet (AD). This study was designed as a true experimental design that assigns 20 rats, and divides them into four groups as follows: P1 (AD 3 months); P2, P3, and P4 (3 months AD + black tea extract administration at dosage 0.015gr/day, 0.03gr/day, 0.045gr/day, respectively). Serum adiponectin level was measured using ELISA method. This study demonstrated that there is an elevation trend of adiponectin level as the dose elevated. However, serum adiponectin level in AD-only group (380.6ng/mL) was not significantly different with treatment group (386.93ng/mL, 404.27ng/mL, and 416.6ng/mL in P2, P3, and P4, respectively) (ANOVA, p = 0.352). Furthermore, there was no significant association between the dosage of black tea and adiponectin levels (Pearson correlation test, p = 0.073, r = 0.373). We concluded that black tea extract increased serum adiponectin level insignificantly in atherogenic diet rats.
Induction hardening of steels with use of the device for incremental forming of round bars HDQT-R 30-12
Authors: Peković M , Vrtáček J , Janda T , Volkmannová J 
Published: February 2020

Abstract
Induction hardening is mainly used for treating parts in which high hardness, wear-resistance, and ductile core are required, such as spur gears, wind turbine rings, and bearings. Innovative induction hardening processes are also developed for complex automotive components, such as camshafts and crankshafts. In the process, steel is heated by passing high-frequency alternating current through a coil which is equivalent to the primary winding of a transformer. The material to be heat-treated is equivalent to a short-circuited secondary winding. The HDQT-R 30-12 device for incremental forming of round bars includes modules which can be used for heat-treating bars after rolling or even without rolling. Heating is provided by five induction coils at a faster rate than in a chamber furnace. In addition, there is less oxidation of the material surface. This paper presents findings related to microstructures and hardnesses in 42CrMo4, 13CrMo4, and S235JR steel grades after heating at different inductor coil power settings with subsequent hardening in a water bath.

Abstract
Piezoresistive pressure sensors are widely used in various fields such as in industries, automobiles, medical applications and many others. To get proper input from the sensors we must have a good sensor having good sensitivity in every type of environmental conditions. The behavior of the sensor also depends upon its thickness, area, material properties etc. This paper is based on the piezoresistive micro pressure sensor having greater sensitivity made of silicon material. Using finite element analysis (FEA) and ANSYS the sensitivity is determined on different dimensions with different loading conditions. The piezo resistors of silicon material are arranged in different patterns and the sensitivity of each plate is determined by having all the results best design for the sensor is achieved.

Published: February 2020

Abstract
The construction of Ubiquitous Power Internet of Things expands the content and scale of data in distribution network. In order to meet the demand of intelligent operation and maintenance of distribution terminals, this paper proposes a method of mining association rules in data to realize evaluation of distribution terminal units. In this method, firstly, the Apriori algorithm with directional constraint of terminals’ functional module is used to mine the correlation indicators system under each divided functional module of terminals. Secondly, the comprehensive measurement of confidence and lift degree is used to increase the objectivity of evaluation’s weights of indicators which found by mining associations rules. Then, combined with the fuzzy comprehensive evaluation method, according to the correlation indicators system, the status evaluation of intelligent distribution terminals is realized. Finally, the historical status data of the actual disabled terminals are selected to verify the good effectiveness of the method that described in this paper.
‘Endless Wonder’ for Whom?: Adaptation, Transformation, and Magical Libraries
Authors: Anjirbag Michelle Anya 
Published: February 2020

Abstract
Books such as Polly Shulman’s The Grimm Legacy series, and made-for-television films and television series such as The Librarians and Warehouse 13 incorporate the idea of a library or repository where artefacts connected to various stories are stored that facilitates new adventures, not through retelling, but by using the space of the library as a contact point for people to encounter the artefacts, linking the past and the present. Though not adaptations per se, they challenge ideas of adaptation, transformation, and fidelity, and offer a new way to access different narratives. The library embedded in the book is a focal point for a societal nostalgia for libraries as potential spaces for knowledge and wonder, reflecting the push to protect libraries in contemporary society. The library artefacts become mechanisms for new, wondrous experiences, connected to and informed by knowledge from the past. The mechanism of the fantasy relies on a meta-construction of the library within the story as a portal, insofar as it relies on the recognizability of the stories embedded within the narrative as symbolically constructed ‘artefacts’. The library here is not just an archive, but a contact zone for wonder in an increasingly digitized age, and a departure point for a new fantastic journey. These narratives become as much about adapting the library as a concept—recalling, renewing, and renegotiating the potential for wonder, discovery, and egalitarian access to knowledge that they can symbolize—as they are about incorporating old stories into new narratives.
Deglobalizing Rule of Law and Democracy: Hunting Down Rhetoric Through Comparative Law
Authors: Bussani Mauro 
Published: February 2020

Abstract
Notwithstanding the well-known differences that run through cultures and traditions, the West has never stopped trying to export its own law into the rest of the world. During and after the colonial era similar endeavors were spreading Western views on how legal issues are to be understood and handled, thereby broadening the West’s area of influence on global legal affairs. More recently, these efforts have overlapped with (and have been blurred by the rhetorical veil of) so-called legal globalization. The focus of this Article is on the attitudes and methods underpinning the ongoing Western attempts to transplant the two pillars of Western civilization, i.e., democracy and the rule of law, into outside contexts. Confronted with processes that concern different legal systems, this Article cannot but take a comparative law approach. Such an approach entails a careful consideration of the historical and contextual factors and will enable an analysis of data that are usually either discarded or underrated in mainstream legal debates. Thus notions, ideas, and debates about the rule of law and democracy will be reappraised from a comparative law point of view in order to both unearth their intimate legal foundations and to scrutinize their potential for being transplanted outside Western societies. The analysis will show how this potential, to the extent that it exists, can only be exploited through a radical shift from the usual way in which the West approaches the legal settings it aims to change.
