Authors: Saleh Fatima Fadhil , Abdulrahman Huda Abdulsalam
Published: August 2022

In order to satisfactorily control the COVID-19 pandemic, the vaccination program against it must be successful, so the aim of this study was to assess the awareness and desire to vaccinate for undergraduate students and the factors that influence the levels of that knowledge. A cross-sectional study was conducted with the participation of 554 undergraduate students from September 19 to October 20, 2021 through online survey. It proved that the vaccination acceptance rate was high (84.1%) and that the majority of their family members are ready to receive the vaccination (64.3%). They also have good knowledge of the vaccine except for the belief in the safety of the vaccine (64.35%). We concluded that despite the belief that vaccines are not safe; the vaccination has been widely accepted. Health education and adequate information about immunizations are important to build confidence about immunizations among nursing students. Thus, the increased vaccination campaigns among nursing students make it one of the ways to combat this epidemic. Keywords: Vaccination, COVID 19, health safety.

In this article, the production of low-cost adsorbents removal of lead from an aqueous solution from tea and coffee waste and a comparison study between them was investigated utilizing a continuous process to explore the kinetic behavior of the created adsorbent. After charring tea and coffee waste, there was a considerable improvement in surface area and other physical properties such as porosity, density, and bulk density. In the continuous system, several parameters such as (bed height, particle size, and flow rate) were tested, and the optimal circumstances (for each experiment) were held constant for the subsequent sets of tests. The optimal circumstances were achieved as follows (bed height=8cm, particle size=250µm, and flow rate 0.5L/hr)and a random set of experiments showed a removal degree efficiency of lead reaching (99 %). As a result, raising bed height and pH will raise the breakpoint value. While reducing the flow rate, initial concentration, and particle size). Increasing the bed height increases the breakpoint value. Particle size will increase the breakpoint as the flow rate decreases. Keywords: Adsorption, Heavy metals , Continuous system, , Lead ions
Pulsatile Drug Delivery System Utilizing Innovative Technology
Authors: Hussein Mayssam , Nathir Israa
Published: August 2022

Drugs might be released immediately or over time. Pulsatile medication release systems, on the other hand, have been increasing in popularity in recent years. Many medications or therapies could benefit from pulsatile drug release, in which the drug is released rapidly after a predetermined lag time. Pulsatile release systems come in pairs: multi and separate pulse. Rupturable dose forms are a prominent type of single-pulse device. Other methods have a drug-containing centre covered by both a swelling surface and a semi - permeable barrier polymer layer or membrane that is semipermeable but not soluble. The full action of the swelling film, and the permeability and mechanical qualities of the polymer covering, have a large impact in the lag time before the rupture. Many significant features in living organisms are controlled either by pulse or temporary release of active ingredients at a particular spot and duration. As a result, innovative drug delivery systems must be created to accomplish pulsed dispersion of a specified quantity of drugs in simulating the action of organisms while reducing adverse reactions. Special emphasis has been paid to the thermolabile poly (N-isopropylacrylamide) and its derivatives hydrogels. Designing drug delivery devices, hydrogels, and other materials. Micelles allows for thermal stimuli-regulated pulsed drug release. So, pulsatile medication delivery is one of those systems that has a lot of promise for people with long-term conditions like arthritis, asthma, and high blood pressure because it gives drugs at the right time, in the right place, and in the right amount.

Published: August 2022

Background: There is evidence of the role of microorganisms, in particular in the throat and skin in psoriasis pathogenesis. This study aimed to investigate the presence of bacterial DNA (bacDNA) in patients' plasma and its association with gut barrier integrity . Methodology: Plasma was collected from 60 psoriasis patients in the flare up stage and 40 healthy controls. BacDNA was detected by PCR amplification using a 16S ribosomal DNA primer. The amplified DNA fragments were then sequenced to determine their bacterial origin. Results: Bacterial DNA was detected in 51 of 60 patients and only in 4 of 40 healthy controls. BacDNA sequencing results revealed that these bacterial species originated from the gut and skin. On the other hand, intestinal fatty acid binding protein (I-FABP) was measured by ELISA technique to investigate the integrity of the intestinal barrier. Serum concentrations of I-FABP were significantly higher in psoriasis patients compared with the healthy group and were positively correlated with the presence of bacDNA in patients' plasma. Conclusion: These findings suggest that psoriasis flare up is associated with translocation of bacteria and its metabolites into the blood stream, causing an immune system response. The specific mechanism of bacDNA in the pathogenesis of psoriasis needs to be comprehensively studied. Keywords: psoriasis, gut barrier, I-FABP, skin-gut axes

Authors: Sultan Awni Ismail , Habash Mohammed Mohammud
Published: August 2022

Currently, there has been a tendency to prefer breast-conserving surgery (BCS) over mastectomy (MC). Therefore, this study came to assess whether this is true when compared with mastectomy. This retrospective study included early breast cancer patients who were registered in government and private hospitals in Kirkuk and Diyala governorates during the period from February 2015 to March 2017, and were followed up after surgery for five years. The enrolled patients (women) were set into (2) groups; the first one was for patients treated with BCS, while the second was for patients who underwent MC. As a preliminary result, it was found that out of the total of (172) participants, (72) were in the BCS, and (100) in the MC. Convergence of age groups was observed between patients in both surgical groups. The results proved that the local recurrence rate amounted to about (9%) in patients undergoing BCS and the survival rate was for the same group (97%). Thus, we concluded that the breast preservation approach is an appropriate and successful choice for early breast carcinoma patients. Keywords: carcinoma, conserving surgery, local recurrence.

Background: The World Health Organization declared the coronavirus disease-2019 (COVID-19) a pandemic in December 2019. COVID-19 can affect most organs of the body but predominantly affects the lungs. Chest infection is associated with hyponatremia primarily due to inappropriate ectopic secretion of antidiuretic hormone. We conducted a six-month retrospective observational study to evaluate the relationship between chest X-ray (CXR) radiological findings and serum sodium levels. Our secondary goal was to assess the relationship between CXR findings and patient outcomes.

Aim of the Study: To assess the relationship between the initial CXR findings, hyponatremia severity, and outcome in COVID-19 infected patients.

Materials and methods: We conducted a retrospective review of CXR findings of COVID-19 patients aged > 18 years. The patients were healthy and had no history of hyponatremia before COVID-19 infection. All recruited patients were admitted to one of four hospitals in Qatar (Hazm Mebaireek General Hospital, Communicable Disease Center, and all affiliated quarantine centers managed under the Communicable Disease Centre, Mesaieed Hospital, and Ras Laffan Hospital) between March and June 2020. We excluded patients with factors that contributed to hyponatremia. Three score grades were established to describe the CXR findings. Patients were divided into three groups by the principal researcher according to their serum sodium levels. A radiologist evaluated the CXR findings with the patient and group information obscured. The principal researcher collected the X-ray scores for analysis with the serum sodium levels. We used SPSS for Windows, Version 15.0. (SPSS Inc., Chicago, IL, USA) and STATA Package Version 12.0 (StataCorp, College Station, TX, USA) to analyze the data. A p-value ≤  0.05 was considered significant.

Results: A total of 414 CXR patients with COVID-19 were recruited; 275 patients had hyponatremia and 139 had normal sodium levels and were used as the control group. Patients with normal serum sodium and hyponatremia were classified into three categories based on the CXR findings. Grade 0 (95), Grade 1 (43), and Grade 2 (137) hyponatremic patients were reported. The mean sodium levels were 133.6, 131.3, and 127.2 mmol/L for Grades 0, 1, and 2, respectively (p < 0.001). More than 95% of the patients who developed hyponatremia were >30 years. Moderate and severe hyponatremia was more prevalent in patients with Grade 1 or Grade 2 CXR findings and were >30 years.

Conclusion: Serum sodium levels in COVID-19 patients correlated well with the severity of the CXR findings observed at the early disease stage. Furthermore, simple CXR scores can be used to identify COVID-19 patients at a higher risk of hyponatremia, length of hospital stay, medical care support type, and mortality.

A critical issue in mine waste management is the management and mitigation of acid rock drainage and metal leaching particularly from waste rock. This requires good understanding and characterization of materials most likely to generate acid pH waters and generate leachable metals and metalloids, as well as the presence of minerals most likely to neutralize acidic pH such as carbonates and certain silicates. For low-sulfidation epithermal deposits in silica-rich volcanic rocks, neutralization minerals are rare. Consequently, determination of acid generation is almost entirely a function of sulfide content of the rocks. By understanding the distribution of sulfide minerals within such a deposit, an initial mine waste management plan can be developed.

The Rochester mine currently exploits a low-sulfidation epithermal gold-silver deposit and is located on the southern flank of the Humboldt Range in west-central Nevada. The Rochester mine is a conventional open-pit mining operation with cyanide heap leaching and Merrill Crowe processing. Silver and lesser gold mineralization occur associated with sulfide minerals hosted in Permian-Triassic Koipato Group rhyolitic units with extensive quartz-sericite-pyrite alteration. Gangue mineralogy of the deposit is dominated by slow or unreactive silicate minerals with little or no carbonate.

Silver-bearing mineralization was controlled by primary hypogene sulfides and secondary supergene oxidation processes, and most of the mineralized material mined to date has been fully or partially oxidized. Oxidation mobilizes and depletes all forms of sulfur from primary sulfide minerals. Due to the low sulfate content and low content of neutralizing gangue phases, the waste rock classification can be based on total sulfur content.

Based on the analysis of pulp samples collected from within the mine area, a sulfur block model was developed and compared to the results of standard acid-base accounting and net acid generation tests. This comparison demonstrates the benefit of the block model in identifying zones of potentially acid-generating material in the mined waste. Application of this information to mine planning has allowed more efficient management of acid-generating mine waste by allowing the operator to develop areas of the waste rock facility to receive the waste in a timely fashion. Such an approach is based on good mine geologic and mineralogical characterization and the use of a representative and comprehensive geologic block model.
Electrochemical Energy Storage and Conversion Systems – A Short Review
Authors: Suller Garcia Marco Aurélio
Published: August 2022

Electrochemical energy production systems – including fuel cells and electrolyzers – are vital technologies to address energy security and environmental demands. Also, their combination for improved performance is essential for future commercial applications. However, their real utilization (and integration with other alternative energy sources) goes beyond efficiency; large-scale penetration of renewable energy in the existing electrical grid systems is challenging due to destabilization possibility. Thus, electrochemical energy storage systems (e.g., electrochemical supercapacitors) are necessary for managing power generation intermittency and grid reliability. Therefore, this ultra-short review provides a brief overview of some of the most promising electrochemical devices for electrochemical energy production and storage for future systems in an engagement scenario.

Authors: Suni Jarno , Komppula Raija , Kortet Raine
Published: August 2022

Competitive fishing is a global phenomenon covering thousands of fishing contests annually. We studied the experiential value of angling competitions from the participants’ point of view by using an online survey data among Finnish anglers who had been on an overnight angling competition trip within the last two years. The theory of consumption values is used as the basis for our theoretical framework, including functional, social, emotional, epistemic, and conditional value, while togetherness was suggested as the sixth value dimension. The value dimensions were measured with 45 variables. We used principal component and cluster analyses to identify three value-based clusters among respondents: Wellbeing seekers, Family-oriented competitors, and Novelty seekers. Novelty seekers were the youngest and least experienced group who are looking for novelty and they want to learn new things in competitive angling. Family-oriented competitors were the oldest and most experienced in competitive angling, and they valued friendship, family, and togetherness more than others. Wellbeing seekers were focused on self-development and positive effects on their wellbeing. Notably, proper and equal competition arrangements were the most important source of functional value. Surprisingly, the role of catching fish per se seems to be a minor contributor to the fishing competition experience value.

The number of alternative tourism types that appeal to niche markets is increasing daily in response to the changing demands and expectations of tourists. Apitourism, which is a blend of nature and culture, has attracted attention and has become an important niche tourism market in recent years. In this study, the tourists’ experiences of visiting the beekeeping museum, which is an attraction within the scope of apitourism, were examined. The notes written in the museum’s visitor book, and the observations made to support the notes, enabled the visitors’ experiences to be classified into 32 codes and six themes. The resulting themes, such as shedding light on the past, experiencing intense emotions, information and awareness, being a recreational activity, features of the museum, and staff. As a result of the study, some suggestions have been put forward for researchers and apitourism stakeholders.

Considering the coronavirus risk, the purpose of the study is to reveal the group differences in travel risk perception, travel behaviour and behavioural intention in terms of the tourists’ sociodemographic characteristics – gender, age and past travel experience. A convenience sampling was used and members of the eligible travel groups on social media platforms were invited to respond to an online survey. A total of 160 responses were obtained from Turkey in January 2021. Exploratory factor analysis, independent samples t-tests and cross-tabulation analysis were performed to analyse the data. This study determined the differences in the risk perception of coronavirus, travel behaviour and travel intention of tourists in terms of gender and age of tourists. Although it is known that the higher the experience, the lower the risk perception, the study showed no differences associated with the past travel experience. This supposes that all tourists, regardless of their past experience, perceived the coronavirus risk in the same way as its influence has been tremendous globally. Consequently, tourism professionals should attract target markets at the appropriate time with compatible strategies regarding the sociodemographic factors.

The COVID-19 pandemic brought significant changes in all spheres of public life. Economically, as well as in terms of behavioural change, tourism has been one of the most affected sectors and nearly two years after the crisis began, the future is still unclear. This paper focuses on changes in tourist behaviour by tracking the shifts and persisting patterns within a one-year period. The study is based on two surveys conducted online in April 2020 and April 2021 and display the trends for a very specific and understudied context – a European country characterized by general distrust to the severity of the virus as well as towards imposed measures against the disease distribution at both national and international levels. Our findings question the wide-spread assumption that health-related concerns are the primary factor affecting tourist behaviour in the pandemic and identify travel restrictions and income as having major significance. Another important observation is the lack of significant changes within the study period, which examines two different situations: the onset of the pandemic that brought a great shock at all levels and a year later, when both objective circumstances and subjective perceptions were not expected to be the same.

The causes of obesity and hypertension are multifaceted. Socioeconomic status, access to healthcareresources, advertising, education about various programs available, and the nature of the program all impact the success rate of any weight-loss initiative.  This provides an opportunity to determine the impact that reducing weight can have on comorbidities related to obesity that include hypertension, diabetes, and hyperlipidemia.  Women who are successful in this battle will gain an increased sense of self-esteem and will have the skills and the knowledge to educate their children about selecting a proper diet and becoming more active to maintain an acceptable weight with the potential to reduce this healthcare epidemic (Remington, Wagner, & Mark, 2010).
“Co-Benefits” as a Lens Through Which COVID-19 Building Upgrades Can Advance Environmental Sustainability, Climate Mitigation and Adaptation, and Social Equity
Authors: Houghton Adele
Published: August 2022

Buildings play a critical role in disaster preparedness and response. They can protect occupants from exposure to an environmental hazard like a hurricane, a flood, or an extreme heat event. On the other hand, if systems break down or structures collapse, they also contribute to the injury and death toll. Buildings have played a similarly contradictory role during the COVID pandemic. On the one hand, they have provided safety and shelter at a time when it is safer to stay physically distant from individuals outside of one’s family unit. At the same time, mechanical ventilation systems have contributed to the spread of SARS-CoV-2, the virus that causes COVID-19. This commentary proposes deploying the public health concept of “co-benefits” as a lens through which COVID upgrades to existing buildings and design considerations for new buildings could be leveraged to advance environmental sustainability, climate mitigation and adaptation, and social equity.

Published: August 2022

In post-Cold War era, defence diplomacy as strategic engagement focuses on a state’s military and defence institutions for a peaceful, non-coercive role to build amicable and cooperative relations with former or potential rivals to prevent and resolve conflicts. This research article argues that Pakistan’s defence diplomacy towards Russia, a former Cold War adversary, has been geared towards reducing hostility and sources of friction to promote and achieve broader foreign policy objectives of Islamabad. It analyzes strategic engagement between Islamabad and Moscow in four categories of defence diplomatic activities: defence agreements, high level exchanges, joint military exercises and port calls. The article concludes that Pakistan’s defence diplomatic efforts (2014-2020) have produced political and strategic-level benefits to prevent conflict and reduce hostility with Russia.
