Authors: Maryi Silvin Sofia , D. Indirani , P. S. Vinothkumar 
Published: August 2022

Background: Determination of gestational age is an important step of pregnancy management and foetal development evaluation in obstetrics. Any error in this gestational age estimation results in prematurity or post maturity and in case if the expected date of delivery is not known, there is high chance of perinatal mortality in the near outcome. Hence it is important in achieving an uneventful gestation to have a sensitive, specific and age independent obstetric biometric parameter that stays constant throughout the gestation. Trans-cerebellar diameters (TCD)/ abdominal circumference (AC) ratio are reliable, constant predictors to assess the gestational age and to evaluate fetal growth. Aim was to compare the accuracy of TCD/ AC ratio with head circumference (HC)/ AC ratio in predicting asymmetrical IUGR.Methods: A prospective study was conducted over a period of one year on 100 clinically suspected IUGR pregnancies who were evaluated with BPD, HC, AC and FL along with TCD were measured for assessing the sonological gestational age. Two morphometric ratios-TCD/AC and HC/AC were calculated. Estimated fetal weight was calculated for all these pregnancies and its percentile was determined. Then those clinically suspected IUGR cases were followed up to delivery and post-delivery new Ballord score and CAN score (clinical assessment of nutritional status at birth) were calculated.Results: In the present study, the sensitivity, specificity, PPV, NPV and DA were 83.93%, 65.91%, 75.81%, 76.32% and 76% respectively for TCD/AC ratio versus respectively for HC/AC ratio in predicting IUGR. Conclusions: Both ratios were gestational age independent and can be used in detecting IUGR with good diagnostic accuracy. However, TCD/AC ratio had a better diagnostic validity and accuracy compared to HC/AC ratio in predicting asymmetric IUGR.
Cardioembolic stroke in patients with atrial fibrillation
Authors: Pramanasari Indra , Alexander Nick 
Published: August 2022

Stroke is a neurological emergency in the form of disturbances in brain function that occur suddenly, it can be focal or global, which lasts for 24 hours or more and even causes death, with no other obvious cause other than vascular disorders. Strokes are generally divided into two main categories: ischemic stroke and hemorrhagic stroke. Atrial fibrillation (AF) is a cardiac arrhythmia and is often associated with stroke, dementia, and death. In our case, an 81-year-old woman came to the ED complaining of sudden loss of consciousness with GCS E2V1M5. A non-contrast CT scan of the head revealed cerebral atrophy and senile cerebellum accompanied by suspicion of infarction in the left globus pallidus. The ECG results showed an irregular rhythm (irregular P-P) leading to AF. AF is a high-risk factor for stroke because of impaired blood pumping, so the risk of clots forming which can then escape and flow to the brain causes blockage of blood flow to the brain and stroke occurs. It is therefore important for routine treatment and control of high-risk patients with heart rhythm disorders such as AF to prevent embolic strokes.

The sound of d spiny lobster (Panulirus homarus) was identified, named rasp; slow rattle; and popping sound
The sound characteristics of spiny lobster (Panulirus homarus) represent its behavior
Passive acoustic and visual record method combination was implemented to analyze the relation between sounds and behavior of spiny lobster (Panulirus homarus)

Abstract
Spiny lobster Panulirus homarus is one of many important economic fishery resources in Indonesia. Continuous exploitation activities in the natural habitat can potentially disturb the sustainability of lobster resources. This species is known to produce sound with certain characteristics and highly dependent on environmental changes. This study aimed to investigate the characteristics of sound as a representation of behaviour. The sound produced by P. homarus was recorded for 24 hours using a hydrophone (a passive acoustic technique). The hydrophone converts the sound wave produced by the lobsters into electric voltage in millivolts, then were converted to a digital number, in order to be saved in a virtual format with the *.wav extension. The video system captured data on behaviors of resting, territoriality, aggression, and social attitudes. The results showed that P. homarus emitted rasp, slow rattle, and popping type of sound, with certain characteristics. All sounds types were characterized by a broadband frequency (4 - 20 kHz), and a source level ranging from 125 - 145 dB re 1 µPa. Rasp sound consisting of 12 - 40 pulses with a sound duration of 100 - 400 ms, represents a defensive behavior. Slow rattle sound with 2 - 7 pulses did not represent a specific behaviour and it is dominant during the night. However, the popping sound with only one pulse represented feeding behavior.

Experimental use of pre-treated pangasius skin as collagen raw material using different acetic acid immersion time
Effects of immersion time on the yield of collagen from pangasius skin
Effects of immersion time on the proximate content of collagen from pangasius skin
Presenting SDS-Page profile of collagen from pangasius skin

Abstract
Pangasius sp. production in Indonesia has reached 384,310 tons in 2019. One of the main waste in pangasius fillet industry is the skin, which reached to 6% of body mass. Fish skins are alternative for making collagen because it has no restrictions for certain religions and ethnicities. Collagen is a protein biomaterial which acts as the main component of connective tissue. Extracting collagen using organic acids such as acetic acid is the most common extraction method. Herein, we report the effects of different immersion time of acetic acid to collagen properties from pangasius skin. In this study, pangasius skin was treated using 10% alcohol with the ratio 1:10 (w/v) for defatting and 0.1M NaOH with the ratio 1:10 (w/v) for eliminating non-collagenous protein. The immersion of 0.5M acetic acid was carried out on pangasius skin with the ratio of 1:20 (w/v), for 24, 48, and 72h at temperature less than 15oC. The sample was salted-out for 24 hours with NaCl until the concentration reached 2.5M, then the sample was freeze-dried at -40oC. This study investigated that longer immersion time affected the properties of pangasius skin collagen. Different immersion time significantly affected the yield of collagen from pangasius skin (p<0.05). Pangasius skin has a potential to be used as collagen raw material, and 72h of immersion time (P3) is suggested to produce pangasius skin collagen with the highest yield and protein content (6.15 % and 9.26 %). Production of collagen from the fish skin will contribute to increase pangasius waste valorization in pharmaceutical industry.

Abstract
Snakehead fish (Channa striata) is an important commodity in South Kalimantan Indonesia. The snakehead fish production was increased due to the capture and intensive culture. The disease is one of the obstacles for production that may happened in cultured- and wild-fishes. The aims of this study were to record and to identify parasite which infected on wild snakehead fish from Kandangan Lama, Panyipatan, Tanahlaut, South Kalimantan. The parasite identification was conducted based on the morphology and the molecular characters. The morphology was observed by light microscope and scanning electron microscope. The 18S rRNA of parasite was amplified using designed primers and followed by sequencing. Spherical cysts were found in abdomen cavity and flesh of snakehead fish. The cylindrical worm with needle shape on both tip end with approximately 1 mm length were moving inside of wall cysts. Alignment analysis of 18S rRNA showed the highest homology at 99.83% with Tanqua tiara. Phylogenic tree showed that this worm is located at distance clade with the nematodes that have been reported to infect snakehead fish. The morphology and molecular results verified that and first report the parasite found in snakehead fish in South Kalimantan was T. tiara species. This nematode parasite may be served as intermediate host.

Cinnamaldehyde decrease the number of green Vibrio bacteria

Abstract
Disease can cause shrimp mortality and high economic losses caused by Vibriosis group. One alternative is using cinnamaldehyde which function as an anti-microbial and inhibit the production of toxins released by microorganisms. This study aimed to evaluate the administration of cinnamaldehyde on the dynamics of Vibrio bacteria and the health status of Pacific white shrimp fed with cinnamaldehyde-containing feed. This study used a completely randomized design (CRD) consisted of 4 treatments and 3 replications consisting of treatment K, A, B, and C which mean feeding without cinnamaldehyde, feeding containing cinnamaldehyde dose of 0.05%, 0.1%, and 0.2% respectively. Parameters included total bacteria (green and yellow Vibrio) in water, intestine, and hepatopancreas, as well as immune responses parameters, including total hemocyte count (THC), respiratory burst (RB), and phenol-oxidase (PO). All data were tabulated in Microsoft Excel 2016 and all statistical analysis was conducted in the SPSS v.22.0 software with one-way ANOVA followed by Duncan Multiple Range Test (DMRT (P=0.05). The results showed that the administration of cinnamaldehyde influences the dynamics of Vibrio and health status of shrimp. At the beginning and at the end of cinnamaldehyde administration, green and yellow Vibrio bacteria are mostly found in water, intestine, and hepatopancreas. The administration of cinnamaldehyde to Pacific white shrimp can reduce the number of green Vibrio bacteria both in the intestine and hepatopancreas as shown in treatments C and B. Cinnamaldehyde also affected the higher percentage of yellow Vibrio bacteria in treatments C and B compared to control (K). The highest immune responses of THC and RB were produced in treatments A and C compared to K. The decrease of green Vibrio bacteria and increased colonization of yellow Vibrio bacteria were correlated with immune responses. The best treatment in this study is treatment C.

Abstract
Bonylip barb (Osteochilus vitattus Valenciennes, 1842) is one of many native fish inhabiting Tamblingan Lake. The information about this species in Tamblingan Lake is rare which requires fulfilment in information gaps for the management of bonylip barb. The aims of this research were to find out the length-length relationship, length-weight relationship, length at first maturity, sex ratio, gonadal maturity stage, gonadosomatic index (GSI), fecundity, as well as spawning period and location in Tamblingan Lake. The fish sample was captured with experimental gillnet that was set in the afternoon and hauled in the next morning. Length and weight of every sample were taken. All samples were dissected to observe the sex and gonad. Fork length was the type of length with higher accuracy to estimate the body weight than the other length character. Growth pattern of this species was isometric. Lm50 of bonylip barb in Tamblingan Lake was 116 mmTL. Sex ratio of bonylip barb was imbalanced (1.00:0.82). Gonad maturity stage I-V was found during the research with GSI between 0.16-15.50 for male fish and 0.43-32.82 for female fish. The highest GSI was found in March, 15.50 for male fish and 32.73 for female fish. Mature fish were discovered in all stations in every month of sampling. The fecundity of bonylip barb ranged between 2,792-279,326 eggs. The length-length and the length-weight showed a strong relationship. The fish was isometric. Based on the growth pattern and the reproductive aspects, the population of bonylip barb in Tamblingan Lake was in good condition.
Coreflooding Evaluation of Fiber-Assisted Recrosslinkable Preformed Particle Gel Using an Open Fracture Model

Published: August 2022

Summary
Recrosslinkable preformed particle gels (RPPGs) have been used to treat the problem of void space conduits (VSC) and repair the “short-circuited” waterflood in Alaska’s West Sak field. Field results showed a 23% increase in success rates over typical preformed particle gel (PPG) treatments. In this paper, we evaluated whether adding fiber into RPPGs can increase the RPPG plugging efficiency and thus further improve the success rate. We designed open fracture models to represent VSC and investigated the effect of swelling ratio (SR), fracture size, and fiber concentration on gel injection pressure, water breakthrough pressure, and permeability reduction. Results show that fiber can increase RPPG strength and delay its initial swelling rate, but an optimized fiber concentration exists. Beyond that, the fiber entangling problem can result in the recrosslinked bulk gel inhomogeneously and impact gel quality. The injection pressure of fiber-assisted RPPGs increased with the SR and fracture width. During post-injection water process, the breakthrough pressure and residual resistance factor increased when the RPPG SR and fracture width decreased. Fiber-assisted RPPGs can dramatically reduce the permeability of the fractured core up to 1.8×106 times. It is observed that the fiber-assisted RPPGs used in the experiment remain in a bulk form in the fracture when we open the fracture after water injection. Not only does the addition of fiber improve the plugging efficiency, but it also prevents particle precipitation along vertical fractures or conduits.
Verification of the geomagnetic field models using historical satellite measurements obtained in 1964 and 1970

Published: August 2022

Abstract
In 2019, the WDC for Solar-Terrestrial Physics in Moscow digitized the archive of observations of the Earth’s magnetic field carried out by the Soviet satellites Kosmos-49 (1964) and Kosmos-321 (1970). As a result, the scientific community for the first time obtained access to a unique digital data set, which was registered at the very beginning of the scientific space era. This article sets out three objectives. First, the quality of the obtained measurements is assessed by their comparison with the IGRF reference field model. Secondly, we assess the quality of the models, which at that time were derived from the data of these two satellites. Thirdly, we propose a new, improved model of the geomagnetic field secular variation based on the scalar measurements of the Kosmos-49 and Kosmos-321 satellites.

Abstract
The efficient migration, survival, and engraftment of transplanted cells are important initial steps toward effective cellular therapies for retinal degenerative diseases. The inner limiting membrane (ILM), which separates the retina from the vitreous cavity, is a major barrier for intravitreally transplanted cells. Focusing on the cellular components of the ILM, we found that the cell adhesion molecule N-cadherin (NCAD) at Müller glia (MG) endfeet helps maintain this barrier. To increase ILM cellular permeability, we modulated NCAD expression via two approaches: an inducible MG-specific knockout animal model and with intravitreal self-deliverable siRNA injections. We show that NCAD suppression enhances retinal migration of multiple cell types after intravitreal transplantation, including mouse MG, human induced pluripotent stem cell-derived retinal ganglion cells, and human dental pulp stem cells. Our study may contribute to the development of targeted approaches for recipient tissue modulation to improve cellular therapies for retinal disease.

Published: August 2022

Abstract
With the migration of the enterprise applications to micro-services and containers, cloud service providers, starting with Amazon in 2014, announced a new computational model called function-as-a-service. In these platforms, developers create a set of fine-grained functions with shorter execution times instead of developing coarse-grained software. In addition, the management of system resources and servers is entrusted to cloud service providers. This model has many benefits, such as reducing costs, improving resource utilization, and helping developers focus on the core logic of applications. But still faces many challenges such as balancing cost, balancing performance, programming models, using current dev tools, containers’ cold start problem, saving data in caches, security issues, privacy concerns, and scheduling challenges like execution time prediction. In this paper, we focus on scheduling and cold start problems. Compromise occurs when keeping warm operating environments which can reduce cold start times but increase costs. In this study, we propose a dynamic waiting time adjustment approach. We aim to create a trade-off by using four different types of decisions at runtime using a heuristic method and analyzing the function dependency graph, functions’ invocation frequency, and other environmental parameters. The proposed method shows a 32% improvement over the fixed-time method (i.e. the method used by Apache OpenWhisk). This comparison is made from the cumulative measurement viewpoint which is a combination of response time, turnaround time, cost, and utilization.

Published: August 2022

Abstract
The biosynthesis of bacterial cellulose (BC) has included a variety of carbon sources, in which the agriculture waste materials have continuously targeted to reduce for sustainable development. Acetobactor xylinus 2526 strain was used to synthesize bacterial cellulose by using jaggery waste as a carbon source in a medium. This article reports the optimization of yield (g/l), crystallinity (%), moisture regains (%), and average pore size (µ) of bacterial cellulose pellicles in dynamic culture conditions. A three factor three level Box-Behnken design has been applied; the three parameters include incubation temperature, shaking rpm, and pH of nitrogen source. Modified media was developed by taking 20 g/L jaggery waste in place of glucose in slandered Hestrin Schramm (HS) media. The optimization of BC resulted in 11.76 g/l yields, 78.9 % crystallinity, 62.7% moisture regain, and 7.3µ average pore size were found optimum for BC production at of 29.23°C incubation temperature, 121.19 shaking rpm, and 5.65 pH of nitrogen source. The physical property of Bacterial cellulose was characterized by X-ray diffractometry, Digital moisture meter, Fourier transform infrared, and Scanning electron microscopy. This article conclude the effect of incubation temperature, shaking rpm, and pH of nitrogen source on bacterial cellulose yield as well as its property by using response surface methodology.
