Authors: Friedrichsen Maria , Hajradinovic Yvonne , Jakobsson Maria , Brachfeld Kerstin , Milberg Anna 
Published: May 2021

Abstract
Acute care and palliative care are described as different incompatible organisational care cultures, with contrasts and contradictions. Few studies have observed the actual meeting between these two cultures. Purpose: To study the meeting and interaction of two different organisational care cultures, palliative care and curative acute wards, when a palliative care consultation team introduces consulting services to acute wards regarding end-of-life palliative care. Methods: An ethnographic study design was used, including observations, interviews and diary entries. A palliative care consultation team visited surgical and internal medicine wards during one year. An integrative bedside education approach was used, where physicians and nurses experienced in PC tried to embed PC principles and interventions into daily practice. The analysis was inspired by Spradley’s ethnography.Results: Three themes were found in the study: 1) Values, illusions, and wording in the acute care culture; 2) Didactic challenges and strategies, and 3) The palliative illusion becomes a fusion. On the acute wards, fast “turn over” was the goal of care: to treat patients quickly and send them home. Primary health care team members believed that they gave dying patients good care, a conclusion not supported by the palliative care team, who identified values problems and a knowledge shortage among all primary team members. Because the primary team did not have time for reflection regarding patients’ whole situation, and wanted to do as much as possible before “giving up”, their patients could be one hour from death before the primary team provided palliative care. After one year, primary team members wanted the palliative care consultation team to continue, since they felt they could not handle dying patients on their own.Conclusion: Palliative care consultation team make changes about end- of- life care when working with primary health care team members on acute wards. The didactic challenges are many and require efforts.
Validation of Satellite-Based Sea Surface Temperature Products Against in Situ Observations Off the Western Coast of Sumatra
Authors: MOTEKI Qoosaku 
Published: May 2021

Abstract
This study validated the sea surface temperature (SST) datasets from the Group for High-Resolution SST Multi Product Ensemble (GMPE), National Oceanic and Atmospheric Administration (NOAA) Optimal Interpolation (OI) SST version 2 and 2.1 (OIv2 and OIv2.1), and Estimating the Circulation and Climate of the Ocean, Phase II (ECCO2) in the area off the western coast of Sumatra against in situ observations. Furthermore, the root mean square differences (RMSDs) of OIv2, OIv2.1, and ECCO2 were investigated with respect to GMPE, whose small RMSD < 0.2 K against in situ observations confirmed its suitability as a reference. Although OIv2 showed a large RMSD (1-1.5 K) with a significant negative bias, OIv2.1 (RMSD < 0.4 K) improved remarkably. In the average SST distributions for December 2017, the differences among the 4 datasets were significant in the areas off the western coast of Sumatra, along the southern coast of Java, and in the Indonesian inland sea. These results were consistent with the ensemble spread distribution obtained with GMPE. The large RMSDs of OIv2 corresponded to high clouds, and it was suggested that the change in the satellites used for SST estimation contributed to the improvement in OIv2.1.

Abstract
In this paper, methacrylic acid (MAA) and 4- vinyl pyridine (4-VP) as functional monomers, ethylene glycol two methyl acrylate (EGDMA) as crosslinking agent, isopropyl alcohol as the solvent, prepared the Cu(II)- and Pb(II)- imprinted polymers(IIPs) submicron spheres by precipitation polymerization. The presence/absence of the template ion in the preparation of the imprinted polymer was confirmed by EDX spectroscopy, and the structure of the particles was investigated using IR, SEM and BET analysis. From different components of crosslinker/monomer(C/M) ratio analysis, C/M at 1:3 was the optimal ratio for preparing IIPs. Atomic absorption spectroscopy (AAS) was characterized the imprinted polymers absorption behavior. The results show that the maximum adsorption capacity of Cu2+ and Pb2+ -imprinted polymer were 26.9mg﹒g−1 and 25.3mg﹒g−1, respectively. They also have good adsorption capacity and superior selectivity property for Cu2+ and Pb2+ in water, respectively. The selectivity factors (α) for Ni2+, Zn2+, Co2+ and Fe2+ were 16.5(Cu2+) and 12.1(Pb2+), 13.8(Cu2+) and 16.2(Pb2+), 10.8(Cu2+) and 10.1(Pb2+), 20.4(Cu2+) and 20.7(Pb2+), respectively. The regeneration experiment result demonstrates an excellent re-utilization property of these two type IIPs, after ten uses, the adsorption capacity can maintain above 60%.

Authors: Le T. D. 
Published: May 2021

Abstract
Context Astrophysical observations play a critical role in the possibility of variations in fundamental physical constants. One of the ways of probing these variations would be based on the evolution of the white-dwarf stars. Aims We use the spectrum of white-dwarf star G191-B2B to find an upper limit on the possible deviation of the gravitational constant with strong gravitational fields. Methods We analyze archive observation of the Hubble Space Telescope Imaging Spectrograph (HSTIS) to determine the possible cosmological deviation of the gravitational constant from the observed gravitational redshift. Results Our analysis provided a strong estimate on an upper bound on the possible space-time variation of the gravitational constant ̇⁄ = (0.238 ± 2.959) × 10 yr comparing with previous results. Conclusions The obtained result in this study offers the possibility of testing parameters of modern unification theories.

Violacein, a microbial product was characterized after continuous attempts to feature it, based on degradation and synthesis procedures, at the University of Liverpool (England), from 1958 to 1960 and only at 2001 was chemically synthesized. It is a quite known antimicrobial and antiviral natural product. New attempts to solve the infection caused by, or find the proper therapy for, COVID19, must adopt multidisciplinary approach. The aim of the current study is to address the targets, possible strategies and perspectives of new technologies and therapies on COVID19. It also hypothesizes the potential of using the therapeutic drug called violacein as multifunctional agent to treat patients at different COVID19 contamination stages. Our experience and knowledge about violacein has led us to extrapolate the potential use of this pigment. Violacein multiple biological activities as also knowledge on its toxicity and antiviral activity enabled suggesting that it could be the new important agent used to treat COVID19. Violacein is highly likely to act as protease inhibitor, at ACE2 receptor level and as immunotherapeutic drug against Covid19. In term of chemotherapy, it will be discussed the actual antiviral used against COVID19, such as, thalidomide, ivermectin and melatonin, among others.

:Failure of embryo implantation has been introduced as an important limiting parameter in early assisted reproduction and pregnancy. The embryo-maternal interactions, endometrial receptivity, and detections of implantation consist of the embryo viability. For regulating the implantation, multiple molecules may be consistent; however, their specific regulatory mechanisms still stand unclear. MicroRNAs (miRNAs) have attracted a lot of attention due to their important effect on human embryo implantation. MicroRNA (miRNA), which acts as the transcriptional regulator of gene expression, is consisted of embryo implantation. Recent studies indicated that miRNAs not only act inside the cells but also can be secreted by cells into the extracellular environment via multiple packaging forms, facilitating intercellular communication and providing indicative information related to various conditions. The detection of extracellular miRNAs provided new information in cases of implantation studies. For embryo-maternal communication, MiRNAs offered novel approaches. In addition, in assisted reproduction, for embryo choice and prediction of endometrial receptivity, they can act as non-invasive biomarkers and can enhance the accuracy in the process of reducing the mechanical damage for the tissue.

Published: May 2021

Proses pemadatan dengan vibrasi untuk mendapatkan beton yang berkualitas memiliki kesulitan ketika diperhadapkan dengan model struktur yang kompleks. Sehingga beberapa dekade terakhir telah dilakukan penelitian dan pengembangan beton yang bisa memadat sendiri, yang dikenal dengan nama self-compacting concrete (SCC). Pengaplikasian SCC di Indonesia masih terbatas karena biaya pembuatannya yang cukup tinggi. Komposisi semen pada beton SCC lebih banyak dari beton konvensional yang artinya menimbulkan polusi udara lebih tinggi. Jumlah produksi semen berbanding lurus dengan jumlah CO2 yang dilepas ke atmosfer, maka industri semen dunia memberikan kontribusi besar terhadap emisi gas rumah kaca global. Beberapa penelitian mulai berinovasi mengkombinasikan SCC dan teknologi penggantian semen secara keseluruhan dengan material pozzolan yang memiliki karakteristik seperti semen. Salah satu alternatif material pengganti semen portland adalah fly ash yang merupakan material buangan pembakaran batu bara di PLTU. Agar Fly ash bisa mengikat seperti semen diperlukan aktivator. Campuran fly ash dan aktivator dikenal sebagai semen geopolimer, sehingga kombinasi dua teknologi beton ini disebut beton self compacting geopolymer dengan material dasar fly ash. Di Indonesia, beton self compacting geopolymer masih terbatas dalam tahap pengujian mix design, sehingga penulis tertarik mengetahui tinjauan ekonomis beton jenis ini, dan bermaksud menganalisa biaya pembuatan beton self compacting geopolymer ini menggunakan material lokal, fly ash dari PLTU II Amurang, Sulawesi Utara. Penelitian dimulai dengan pemeriksaan material lokal di Sulawesi Utara untuk mencari mix-design beton. Dilanjutkan dengan melakukan pengujian experimental untuk mendapatkan karakteristik kelecakan beton segar dan kuat tekan beton. Selanjutnya dilakukan analisis biaya produksi berdasarkan mix-design per 1 m3 beton. Pengujian kelecakan dari pasta Beton Self Compacting Geopolymer dengan material dasar fly ash melalui metode slump flow,V-funnel test dan L-Box Shaped test menunjukkan bahwa sudah memenuhi syarat SCC juga menghasilkan beton mutu K-250. Beton geopolimer dikombinasikan dengan beton SCC yang biayanya memang sudah relatif tingi menghasilkan biaya pembuatan yang juga tinggi.

Authors: Treer Tomislav 
Published: May 2021

Abstract
The aim of this research is to compare the average individual weight of the four most important fish species in fisheries (Cyprinus carpio, Silurus glanis, Esox lucius and Sander lucioperca), caught by angling in different parts of the Sava River catchment in Croatia. Significant differences were expressed between the counties along the Sava River catchment, with the smallest specimens (p˂0.05) caught in Vukovar-Sirmium county. Artisanal fishery is mostly developed in that part of the Sava River, along with angling in both countries – Croatia and Bosnia and Herzegovina. Furthermore, the inflow of the River Bosna passes through urban and industrial cities of Bosnia and Herzegovina. It can be concluded that implementing recreational fishing surveys with the specific aim of obtaining data on average individual weight is useful for fishery management.

Abstract
The construction industry consumes a large quantity of cement, which therefore leads to a high CO2 emission due to the cement manufacture. The partial replacement of cement by supplementary cementations materials (SCMs) is considered as the most promising alternative to reduce the environmental impact of this industry. This investigation aims to evaluate the performance of calcinated clay (calcined bentonite at 850 °C) used as partial replacement of cement in cement-based mortar. The evaluated performances include the physico-chemical and mechanical properties, as well as microstructural characteristics.. Various characterization tests, including laser granulometry, X-ray diffraction (XRD), and X-ray fluorescence spectrometry (XRF) have been investigated. In addition, the hardened properties of different mortar mixtures were also investigated. Mortar mixtures incorporating different calcinated clay percentages corresponding to 8, 10, 12, and 14%, by mass of total binder content, were proportioned. Termogravimetric analysis (TGA) and its derivative (DTG), Differential scanning calorimetry (DSC), and microstructural (Scanning electron microscopy (SEM)) analysis were carried out on samples of mortar mixtures. Furthermore, the 28-d hardened properties were assessed to assess the pozzolanic activity of the investigated mixtures. Strength activity index (SAI), DSC, and TGA analyzes are presented. The obtained results showed that all the mixtures exhibited adequate pozzolanic activity conforming to the ASTM C618 specifications.

Abstract
Chronic Hepatitis C virus (HCV) infection is defined as persistence of HCV RNA in the blood for more than six months. HCV is a major cause of chronic liver disease and cirrhosis. It’s serious public health problem, affects about 71 million people worldwide. HCV doesn’t destroy hepatocytes directly. It activates the host's innate and acquired immune system and causes liver injury indirectly. Behind hepatic, HCV can cause extra-hepatic manifestations. One of them is renal disease which can lead to end-stage renal disease, ESRD. The prevalence of HCV infection in patients on hemodialysis is high, ranging from 5% to 60%. HCV infection is a significant cause of morbidity and mortality in patients with ESRD on hemodialysis. In this review, we discuss HCV infection and chronic renal disease as comorbidities, their severity and outcome.

The focus of this research is to analyze variations in the type of rope material and size as a link for measuring the force on a centrifugal pump, namely to find out the type of material and the size of the rope that is suitable to minimize the loss of force contained in the wire. To find out the type of calculation and comparison of the values for various types of material. From the tensile test that has been done, the highest UTS (Ultimate Tensille Stress) value was obtained in a polypropylene monofilament rope specimen with a stress value of 602.17 kgf with 382.14% elongation. The highest stress calculation value data was obtained by the Polypropylene monofilament rope specimen with a value of 738,85 at elongation to 360%. The highest modulus of elasticity obtained by Nylon rope was 4,564 . This shows that the modulus of elasticity is inversely proportional to the stress value, which was the stress value of nylon straps that was the highest compared to other specimens but had the highest elastic modulus value among other specimens.
