Photocatalytic decolorization of methyl orange dye using SnO2-TiO2 nanocomposite particles synthesised by Ultrasonic Assisted Co-Precipitation Method

The ultrasonic-aided co-precipitation method was used to create SnO2-TiO2 nanocomposite particles. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and UV-vis spectroscopy were used to characterize the nanocomposite particles. XRD patterns revealed the crystalline structure of particles and the average particle size determined by Debye Scherrer’s equation was found to be 11.355, 4.9577, and 4.333 nm for TiO2 nanoparticles, SnO2 nanoparticles, and SnO2-TiO2 nanocomposites, respectively. The Ti, Sn, and O species were confirmed to exist by energy-dispersive X-ray spectroscopy (EDS). The UV absorption peaks at 288, 305, and 350 nm were attributed to SnO2, TiO2-SnO2, and TiO2 respectively. The photocatalytic aspect was investigated in a model organic contaminant (methyl orange). Data obtained by the above-mentioned characterization methods confirmed the superior photocatalytic activity of SnO2-TiO2 nanostructure than SnO2 or TiO2 alone

The Function of Micro Credit System in Social Amendment A Case Study on Rajshahi District in Bangladesh

Micro-credits an extremely small loan given to impoverished people to help them become self employed havebecome an important tool in development economics and play an essential role in the fight against poverty, inparticular with respect to the self-sufficient of women. Since Muhammad Yunus, the founder of the Grameen Bank2,received the Nobel Prize for Peace in 2006, microcredit-systems have been increasingly conceptualized as part of aprofit-oriented “financial system approach”.For more than twenty years, microcredit has been widely heralded as theremedy for world poverty. Recent news stories, however, have sullied microcredit’s glowing reputation with reportson scandals, exorbitant compensation to managers, skyrocketing interest rates, and aggressive marketing schemes.Once praised as a universal panacea, microlenders are now being widely attacked as predatory loan sharks. (Korten,2011)However, in this paper we will discuss different approaches to micro-credits dealing with the question of howfar different concepts influence societal gender arrangements and under which circumstances micro-credits are usefultools for the self-sufficient of women in a sustainable way. For this reason, the results of an empirical studyconducted in Rajshahi will be presented in order to develop a multilayer model for the self-sufficient of womenwhich shows possible impacts of micro-credits on the individual level (micro level), the community level (centrallevel) as well as the socio-political level (macro level)Keywords: Self -sufficient Women, Micro credit, Social Amendment, Fund for Development (SFD)

Awareness and likelihood of accepting COVID-19 vaccines among the university students of Bangladesh

Massive vaccination is very important to end the coronavirus disease 2019 (COVID-19) pandemic. This study determined the willingness to receive a COVID-19 vaccine by the university students of Bangladesh and identified their apprehension about the effectiveness and safety of COVID-19 vaccines. Students were invited to complete an online cross-sectional survey (April 3 to June 10, 2021) to explore the intention to receive a COVID-19 vaccine and other factors regarding the responsiveness of the COVID-19 vaccine. Among the 191 respondent students, 52.9% willingly agreed to receive a vaccine, where the remaining was either not decided yet (27.7%) or was not intended to get vaccinated (15.7%). The odd of getting a vaccine were only 1.15. About 83.2% of students were conscious about the severity of COVID-19 and many students responded that they are well-versed about vaccine activity (67.5%) and risk factors (66%). Among the approved vaccines, most students preferred the Oxford-AstraZeneca COVID-19 vaccine ChAdOx1 (38.7%) and Pfizer-BioNTech COVID-19 vaccine BNT162b2 (34%). As some of the students still have lesser intent to accept vaccines, public health officials need to be more proactive to focus on vaccine safety and benefits to enhance vaccine coverage among university students of Bangladesh

Does Carbon Emission Matter for Health Care Expenditure? Evidence from SAARC region using Panel Cointegration

This study investigates the impact of increased carbon emissions on per capita health expenditure exploiting the panel data with Engle – Granger based cointegration test, Fully Modified Ordinary Least Square (FMOLS) and Dynamic Ordinary Least Square (DOLS) method. Data for the South Asian Association for Regional Cooperation (SAARC) countries from 1995 to 2014 have been collected from World Development Indicators (WDI). The confirmation of integration order of the variables has been made using two panel unit root tests suggested by Im – Pesaran – Shin, 2003 (IPS) and Levin, Lin & Chu, 2002 (LLC). Following the procedure suggested by Pedroni (1999, 2003) and Kao (1999), existence of long run relationship has been examined among the variables. Application of Fully Modified Ordinary Least Square (FMOLS) and Dynamic Ordinary Least Square (DOLS) further confirmed the presence of long run significant positive relationship between carbon emissions and per capita health expenditure. The coefficients of carbon emissions varied from 0.246 to 0.355 under the model estimated by FMOLS while the coefficients varied from 0.198 to 0.283 under the model estimated by DOLS. The findings can be generalized by saying that increased carbon emissions due to environmental degradation would increase the health expenditure as well as cost of the nations

A study on the welfare of the animals in zoo negara / Liyana Muhd Fuad ...[et al.]

In recent times, there have been many complaints made regarding the welfare of zoo animals by both the public and NGO's upon Zoo Negara. This forms the basis of the research in the light of animal suffering, standards of a zoo and the adequacies of the legislation and execution of laws. This paper sets out to examine the sufficiency of local laws and its enforcement in protecting the welfare of the animals of Zoo Negara as the national zoo of Malaysia. The primary legislation that provides for wildlife in Malaysia is the Protection of Wildlife Act 1972 which is only applicable in West Malaysia, which applies to the targeted area of research, Zoo Negara. Loopholes or shortcomings of the said Act are found throughout the research and has been affirmed by most of the people interviewed for the purpose of this paper. However, problems may surface as to the matter of jurisdiction or limitations of power to compel or take legal action on established zoos. Where rulings based on the old legislation may have been efficient in earlier days, it would be absurd to say the same for its implications 30 years down the road. At the time of research however, the writers were pleased to hear that the Act is soon to be revised. It has been said that the title in itself could be altered, with what is believed to be additional provisions and amendments supplying to a wider scope of laws. Therefore, it may be rightfully presumed that the current Protection of Wildlife Act is questionable and rather ineffective in its content and enforcement in providing protection of welfare for the zoo animals in Zoo Negara

In vitro cytotoxic and in vivo anxiolytic study of methanolic crude extract of Streculia villosa seeds

We have aimed to evaluate the in vitro cytotoxic and in vivo anxiolytic and sedative activities of the methanolic extract of Sterculia villosa roxb seeds. The dried powder of the seeds was extracted with methanol which was then tested to ascertain the neuropharmacological and cytotoxic potentials. The methanolic extract of Sterculia villosa roxb were subjected to Brine Shrimp lethality bioassay for possible cytotoxicity having LC 50 of 8.672μg/ml. However, fractions produced concentration dependent increase in percent of mortality of Brine Shrimp nauplii indicates the presence of cytotoxic property. We also have studied for possible sedative and anxiolytic activity of the methanolic seed extract of Sterculia villosa roxb in mice. This study includes hole cross, open field, thiopental- sodium induced sleeping time and elevated-plus maze (EPM) tests at the dose of 200 mg/kg while on the peripheral and central nervous system the extract mild to moderately decreased the locomotor activity of mice in hole cross, open field and EPM test. However, the extract moderately has minimized the onset of sleep and slightly has maximized the duration of sleep while administered with thiopental sodium

Phytochemical analysis and hepatoprotective activity of Raphanus sativus var. sativus in Sprague-Dawley rats

Purpose: To determine the phenolic and flavonoid contents of R. sativus rhizome ethanol extract and the hepatoprotective effect of the extract in rats. Methods: Folin–Ciocalteau and aluminum chloride colorimetric tests were used to determine the contents of phenols and flavonoids in the R. sativus extract. Male Sprague-Dawley rats induced with CCl4 to develop hepatotoxicity were treated orally with R. sativus extract for 4 weeks. The  antioxidant and anti-inflammatory effects of the extract on the liver were determined by evaluating the concentration of oxidative analytes, serum liver enzymes and lipids, and hepatic histopathology and cytochrome P450 2E1 expression. Results: R. sativus extract significantly (p < 0.05) reduced the hepatotoxic effect of CCl4 via its antioxidant activities and protection of liver tissues from oxidative damage. Conclusion: The hepatoprotective effects of R. sativus rhizome ethanol extract are attributed to its highphenolic and flavonoid contents. Keywords: R. savitus rhizome, Phenols, Flavonoid contents, antioxidant, Hepatoprotectiv

Verify and trust: A multidimensional survey of zero-trust security in the age of IoT

The zero-trust (ZT) model assumes that all users, devices, and network traffic should not considered as trusted until proven. The Zero-trust model emphasizes the importance of verifying and authenticating every user and device, and limiting access to resources based on the principle of least privilege. Under the principle of the zero-trust model, devices are granted access after they have been successfully presented with their authentication credentials and access rights based on different factors, such as user identity, device health, location, and behaviour. Access controls are then continuously evaluated and updated as user properties, locations and behaviour change. The zero-trust model can be applied in various domains (healthcare, manufacturing, financial services, government etc.) to provide a comprehensive approach to cybersecurity that helps organizations to reduce risk and protect critical assets. This paper aims to provide a comprehensive and in-depth analysis of the zero-trust model, its principles, and its applications, as well as to propose recommendations for organizations looking to adopt this approach. We explore the major components of the zero-trust framework and their integration across different practical domains. Finally, we provide insightful discussions on open research issues within the zero-trust model in terms of the security and privacy of users and devices. This paper should help researchers and practitioners understand the importance of a zero-trust framework and adopt the zero-trust model for effective security, privacy, and resilience of their networks

Doctors' approaches to decision support in counseling patients with localized prostate cancer: an Asian perspective

There are many treatment options for localized prostate cancer, and there is clinical equipoise in relation to the treatment outcomes. This study aimed to explore doctors’ approaches to decision support in counselling patients with localized prostate cancer in a country with a less established system of support and care delivery for cancer treatment. Four in-depth interviews and three focus group discussions were conducted with seven government policy makers/consultant urologists, three oncologists, four private urologists and six urology trainees in Malaysia between 2012 and 2013. Doctors facilitated the treatment decision by explaining about the disease and the treatment options, which included monitoring, side effects and complications of each treatment option. Paper-based (charts and diagram drawings) or electronic (ipad apps and websites) illustrations and physical models were used as patient education aids. Further reading materials and websites links were often provided to patients. Patients were given time till subsequent follow up to decide on the treatment and family involvement was encouraged. Referral to other healthcare professionals (oncologist, radiotherapist or other urologist) for second opinion was offered to the patients. The doctors would recommend patients to speak to prostate cancer survivors for peer support but official support groups were not easily accessible. This study highlighted a multi-faceted approach to support patients with localized prostate cancer in making a treatment decision. It not only involved the doctors (urologist or oncologist) themselves, but also empowered the patients and their social network to support the decision making process
