Hepatitis B Surface Antigen And Viral Dna Detection And Prevalence In Nige-Ria, Abazuh Uchenna Desmond, Ohiengbomwan Onaiwu Tola, Adeolu Isaac, Yusuf Mercy

Makara Journal of Science

81818app手机版下载Hepatitis B infection is a major public health issue with a high mortality rate. It is caused by hepatitis B virus (HBV), a small incomplete hepadnavirus with several open reading frames (ORF). High mutation rates of the HBV ORFs due to the virus’ replicating strategy are associated with the development and emergence of mutant strains, which may result in occult infections that are undetectable by conventional diagnostic assays. In this study, we first investigated the presence and prevalence of hepatitis B surface antigen (HBsAg) and HBV DNA among 204 patients visiting the specialist hospital in Osogbo, Nigeria, by using the ...

Solid Waste Co-Conversion By Hydrothermal Treatment Using Natural Zeolite, Lalak Tarbiyatun Nasyin Maleiva, Chandra Wahyu Purnomo

Makara Journal of Science

81818app手机版下载Hydrothermal treatment is a thermal conversion technology for processing high-moisture-content solid waste to coal-like materials. In this research, mixtures of sawdust and polyethylene terephthalate (PET) waste were treated in a 2000 mL hydrothermal reactor to produce hydrochar and a liquid product. The effects of zeolite addition and temperature variations during the treatment on the product characteristics were investigated. During the treatment, the utilized temperatures were 180, 200, and 220 °C, and the zeolite contents in the mixture were 10 and 20 wt%; the temperature and zeolite content were varied, while the other processing parameters were fixed, i.e., a biomass-to-PET ...

Studies Of The Removal Of Pb2+ And Cd2+ From Aqueous Solutions Using Pocl3 Cross-Linked Carboxymethyl Derivatives Of Legume Starch, Ayodele Akinterinwa, Ebun Oladele, Albert Adebayo, Olubode Ajayi

Makara Journal of Science

Starch was extracted from “Kwakil” bean and cross-linked with POCl3 (1% v/w of starch dry basis [db]). The POCl3 cross-linked starch (PCS) was further carboxymethylated with sodium monochloroacetate (5% to 30% w/w of starch db) to obtain the POCl3 cross-linked carboxymethyl starch (PCCS) derivative. The PCS and PCCS derivatives were used for batch adsorption of Pb2+ and Cd2+ in aqueous solutions, and the change in concentration was monitored using an atomic adsorption spectrometer. Carboxymethylation increased the adsorption of ions (Cd2+, 95% to 96%; Pb, 65% to 94%); however, this was not sustained ...

Makara Journal of Science

81818app手机版下载Currently, environmental degradation caused by heavy metals has become a serious concern of many countries. To monitor the concentration of heavy metals in the environment, an in-situ sensor that can measure in real time and has high quality, sensitivity, and flexibility is essential. We proposed a modified multipath ring resonator (MPRR) based on silicon-on-insulator technology with additional gold nanodisk (GND) on top of the ring to increase its sensitivity. To prove the effect of GND on the sensitivity of the modified MPRR, finite-difference time-domain simulations were conducted. Results showed that the average sensitivity of the modified MPRR was 675 nm ...


Key Deposition Parameters For Short-Type Zno Nanosheets Electrodeposited Under Galvanostatic Mode, Gerald Ensang Timuda, Dhimas Harjanto, Wahyu Bambang Widayatno 2020 Research Center for Physics, Indonesian Institute of Sciences (P2F-LIPI), Building 442 Kawasan PUSPIPTEK, Banten 15314, Indonesia 81818app手机版下载

Key Deposition Parameters For Short-Type Zno Nanosheets Electrodeposited Under Galvanostatic Mode, Gerald Ensang Timuda, Dhimas Harjanto, Wahyu Bambang Widayatno

Makara Journal of Science

Studies on the deposition of ZnO nanosheets grown vertically and perpendicular to conductive substrates have been conducted to obtain tall-type nanosheets (approximately 15 µm in height). However, some applications require short-type nanosheets with a height of about 1µm or less. In this study, short-type ZnO nanosheets were electrodeposited on indium-doped tin oxide substrates under galvanostatic (constant current) mode for a short deposition time. Then, the key parameters to form nanosheet layers with a height in the micrometer order and with good coverage were evaluated. Deposition was performed at −1 mA/cm281818app手机版下载 for 60 s. Ar gas was initially bubbled ...


Malonic Acid As A Green And Efficient Catalyst For The Mass-Scale Synthesis Of Pyrrole Medicinal Drugs, Farzaneh Mohamadpour 2020 Young Researchers and Elite Club, Shiraz Branch, Islamic Azad University, Shiraz 7184948174, Iran 81818app手机版下载

Malonic Acid As A Green And Efficient Catalyst For The Mass-Scale Synthesis Of Pyrrole Medicinal Drugs, Farzaneh Mohamadpour

Makara Journal of Science

A green and naturally biodegradable malonic acid synthesis of highly substituted dihydro-2-oxopyrrole derivatives has been accomplished via one-pot four-condensation of amines (aromatic or aliphatic), dialkyl acetylenedicarboxylate, and formaldehyde under mild reaction conditions. The notable advantages of the present procedure are a green, low cost, and efficient catalyst; operational simplicity; no need for chromatographic purification steps; short reaction times; and good to high yields.

Makara Journal of Science

81818app手机版下载Aquatic stressors are known to cause biological impairment that can result in biodiversity loss in several Marine Protected Areas (MPA), including in Menjangan Island, West Bali National Park. The object of this study was to correlate the changes in water quality parameters with the biological effect of Crown-of-Thorns starfish (CoTS) population dynamics and to assess the most applicable parameters for continuous environmental monitoring. Field observations and surveys were conducted three times in 2017, during the wet season, dry season and season transition, in order to assess the effect of seasonal variability. Redundancy Analysis (RDA) was performed to determine the relationship ...

Instability Of Glucocorticoid Metabolites In Coyote Scats: Implications For Field Sampling, Erika T. Stevenson, Eric M. Gese, Lorin A. Neuman-Lee, Susannah S. French

Human–Wildlife Interactions

Studying physiologic stress responses can assist in understanding the welfare of animals. One method of measuring the physiologic stress response is evaluating concentrations of glucocorticoid metabolites in feces. Previously, using an adrenocorticotropic hormone challenge, we found fecal glucocorticoid metabolite levels were a reliable indicator of physiologic stress response in coyotes (Canis latrans). We determine whether glucocorticoid metabolite concentrations remain stable when collecting feces over a 2-week period, a timeframe commonly used in scat surveys for wild canids. We collected feces from 6 captive coyotes maintained at the U.S. Department of Agriculture, Wildlife Services, National Wildlife Research Center, Predator Research ...
