Objectives:
Our aim was to identify the epidemiological characteristics and transmission patterns of coronavirus (COVID-19) among pediatric patients in the multicultural and multiethnic city of Al Ain in the United Arab Emirates (UAE).

Method:
A retrospective study was conducted by abstracting data from the electronic medical records of pediatric patients with COVID-19 from two major public hospitals in Al Ain. The data of patients from birth through 16 years of the cases with COVID-19 confirmed by reverse transcription-polymerase chain reaction were obtained. In addition to the epidemiological characteristics, transmission patterns, comorbidities, index cases, travel history, and coinfection with other viruses were analyzed. Cohen's kappa was used to assess interrater reliability and descriptive data. Chi-square test was used to assess significant differences between the variables and was conducted using Statistical Product and Service Solutions software.

Results:
We identified 298 (150 males, 148 females) laboratory-confirmed cases. The patients’ median age was 7 years. Of these, 50% had parents who also tested positive. Most patients (86.9%) were healthy without any known medical problems. The coinfection rate was ~2%.

Conclusion:
The epidemiological characteristics of children with COVID-19 in Al Ain are similar to those observed internationally. Children of all ages appeared to be susceptible to COVID-19 and no significant sex or ethnicity differences were detected. Furthermore, this study provides strong evidence of human-to-human transmission.
Prevalence, risk factors and quality of life of Lower Urinary Tract Symptoms (LUTS) among men attending Primary Care slum clinics in Bangalore
Authors: Kant Priyesh , Inbaraj Leeberk Raja , Franklyn Nirupama Navamani , Norman Gift 
Published: July 2021

Background:
Men, more than 50 years of age, have a higher incidence of lower urinary tract symptoms (LUTS), and this increases with the advancing age. The prevalence of LUTS varies in different geographical areas across the world, and studies have reported that LUTS in men may significantly affect the quality of life (QoL) and influence their health-seeking behavior. Early detection of LUTS is essential as it is related to several complications. This study aimed to estimate the prevalence of LUTS and factors associated with LUTS and health-seeking behavior.

Methods:
We interviewed 201 men (>50 years) attending two urban primary care clinics in Bangalore using the IPSS questionnaire and calculated the prevalence of LUTS. Factors associated with LUTS and health seeking-behavior were tested using the Chi-square test. A P-value less than 0.05 was considered as significant.

Results:
The prevalence of LUTS was 85%. LUTS was significantly associated with those having diabetes and those consuming more than two cups of tea per day. The most common symptom was nocturia (85.4%) and a weak stream (35.0%). Moderate and severe LUTS were significantly associated with poor QoL score (P < 0.0001). Only 9.3% of the men sought medical help in spite of their symptoms, and the most common reason for seeking health care was the disturbance they had due to the urinary symptoms (81.3%).

Conclusions:
Family physicians should be aware that a significant proportion of the men in the age group of 50 years suffer from LUTS, and eliciting the same is essential during the process of consultation.

Authors: Osborn Jenit A. , Sriram Rm , Karthikeyan S , Ravishankar S.L 
Published: July 2021

Introduction:
India is the first country to implement National Family Program in 1952. Acceptance of contraceptive methods is influenced by various factors at the individual, family, and community level with their roots in the socioeconomic and cultural milieu of Indian society. This study was carried to find the contraceptive prevalence rate among eligible couples as well as to find the factors influencing it in a rural area of Coimbatore.

Methodology:
The study was carried out using the data extracted from the family health survey conducted by trained field staff for the purpose of furnishing details regarding people residing in the field practice area of Rural Health Training Centre (RHTC), Vedapatti located in Coimbatore district after obtaining Institutional Human Ethical clearance. All eligible couples were included for the study. Contraceptive prevalence is expressed in percentage with 95% Confidence interval. Univariate analysis (Chi-square test) was done to find the association between contraceptive acceptance and independent variables. Strength of association is determined by odds ratio with 95% Confidence Interval (CI). P < 0.05 was considered statistically significant.

Results:
Contraceptive Prevalence Rate among eligible couples was found to be 75% (95% CI: 73.6–76.4). Most commonly used method among the study participants was tubectomy (81.6%), followed by condoms (11.4%), intrauterine devices (6.3%), and oral contraceptive pills (0.7%). Higher age of the women, religion, educational status of the women, socioeconomic status, working status of the women, number of living children, age at the time of marriage, and age at the time of first child birth were found to have statistical significant association with higher usage of contraception.

Conclusion:
The contraceptive prevalence rate was found to be higher in this study population and multiple factors were influencing the contraception usage among the eligible couples.
Copper slag as a potential waste filler for polyethylene-based composites manufacturing
Authors: Hejna Aleksander , Kosmela Paulina , Barczewski Mateusz , Mysiukiewicz Olga , Piascki Adam 
Published: July 2021

The present study aimed to analyze the application of waste material from copper production– copper slag (ŻŻL) as filler for composites based on the high-density polyethylene (HDPE). Copper slag filler was introduced in the amounts of 1–20 wt%, and its influence on the appearance (color analysis), chemical structure (Fourier-transform infrared (FTIR) spectroscopy), microstructure (optical microscopy), as well as static (tensile tests) and dynamic (dynamical mechanical analysis (DMA)) mechanical properties of composites were investigated. Proper dispersion of filler implicated that the incorporation of up to 5 wt% of filler caused only slight, 5% drop of tensile strength, with the simultaneous 16% rise of Young’s modulus. Further increase of filler loading resulted in higher values of porosity and the rise of the adhesion factor, determined from DMA results, which led to the deterioration of mechanical performance. Moreover, spectroscopic analysis of PE-ŻŻL composites indicated that the analyzed filler might be applied as a coloring agent, and the appearance of composites may be engineered by adjustment of filler loading.

Coupled effects of hydrophilic nano silica oxide and anatase nano titanium oxide on strengths of oilwell cement
Authors: Mabeyo Petro E , Gu Jun 
Published: July 2021

The life of oil wells depends on the stability of cement sheath and bond strength with the formation and casing. Extreme subsurface conditions cause substantial stresses on the cement sheath resulting in a serious impact on well integrity. The recommended API cement for oilwell fails to provide the required durability of the cemented well due to such conditions. Supplementary cementitious materials such as nanoparticles are added to improve the cement for long-lasting zonal isolation. In this study, the compressive and shear bond strengths of oilwell cement containing nano-SiO2 and nano-TiO2 were studied at 80 °C for 3, 7, 14, and 28 days of hydration. The XRD, TG, and DSC were used for the analysis of cement hydration products. The results revealed that both nano-SiO2 and nano-TiO2 increased strength evolution. A ternary system made with 2% nano-SiO2 and 2% nano-TiO2 improved compressive strength by 22.6 and 48.4%, while the shear bond strength increased by 110.6 and 55% at age of 3 days and 28 days, respectively, compared to their corresponding binary systems. Therefore, these results remark the potential of replacing an appropriate proportion of oilwell cement with coupled nano-SiO2 and nano-TiO2 to ensure cement sheath structure durability in the annular and long-lasting zonal isolation.

Effects of Xanthan gum on rheological properties of Aloe vera-Moringa leaf juice blends
Authors: Matabura Victor V , Rweyemamu Leonard MP 
Published: July 2021

Understanding the impacts of hydrocolloid agents on the rheological properties of nutraceutical beverages like Aloe vera-moringa juice blend is very useful for functional properties and product stability. To this end, the effects of xanthan gum on rheological properties in Aloe vera-moringa leaf juice blends were investigated using a Brookfield rheometer. Aloe vera-moringa leaf juice blends were prepared and then incorporated with xanthan gum at different ratios (w/w) of 0.2%, 0.4%, 0.6%, 0.8%, and 1%. The results revealed that the viscosity of Aloe vera-moringa juice blend was strongly affected by the xanthan gum addition. The viscosity profiles depicted a decreasing trend in viscosity when a shear rate increased. The Aloe vera-moringa leaf juice blend changes from a Newtonian fluid to the non-Newtonian fluid as the xanthan gum fraction increases. Moreover, shear stress was observed to increase with increasing in xanthan gum concentrations. For quantitative analysis, both Power-law and Bingham model equations were fitted to experimental data to easily describe the flow behaviour of the Aloe vera-moringa leaf juice blends. The juices added with xanthan gum of 0.4% to 1% were found to show a shear-thinning behaviour, since the flow behaviour index, n < 1. This implies that the apparent viscosity decreases as the shear rate increases.

Authors: Agape Kusiluka , Ndesendo Valence MK , Begum Sartaz 
Published: July 2021

This study screened aflatoxin-producing fungi in maize and groundnuts from Dodoma, Singida and Iringa regions in Tanzania, and assessed the level of peoples’ awareness on aflatoxins health effects. One hundred and twenty samples (20 each crop) were collected and inoculated on Sabouraud dextrose agar and one hundred and eleven samples were observed to have fungal growths that were identified to belong to four genera, namely Aspergillus, Rhizopus, Mucor and Dermatophyte with occurrence frequencies of 75, 2.5, 5 and 10%, respectively. Among the four screened genera of fungi, Aspergillus was observed to be the major aflatoxin-producing fungi. Five species of genus Aspergillus, namely A. flavus, A. parasiticus, A. niger, A. fumigatus, and A. terreus were isolated with frequencies of 39.1, 10, 7.5, 15.8 and 2.5%, respectively. Macromorphology and micromorphology of isolated Aspergillus spp were also observed using a light microscope. Furthermore, it was noted that the prevalence of fungi and aflatoxins contamination is more in groundnuts than in maize. In terms of awareness in individuals concerning aflatoxins, only 34% respondents in Dodoma, 29.9% in Singida and 24% in Iringa were aware of aflatoxins. Therefore, the creation of awareness and sensitization on aflatoxins health effects to the people is an important part of intervention ways to forestall and control aflatoxins in Tanzania.

Thermodynamic analysis of a variable viscosity reactive hydromagnetic couette flow within parallel plates
Authors: Hassan Anthony R , Lawal Olufemi W , Amurawaye Funmilayo F 
Published: July 2021

This investigation is to consider the impact of a temperature-dependent variable viscosity of a reactive hydromagnetic Couette fluid flowing within parallel plates. The variable property of the fluid viscosity is thought to be an exponential relation of temperature under the impact of magnetic strength. The differential equations controlling the smooth movement of fluid and energy transfer are modeled and solved by using the series solution of modified Adomian decomposition technique (mADM). The outcomes are shown in tables and graphs for different estimations of thermophysical properties present in the flow regime together with the rate of entropy generation and irreversibility distribution outcome.
Keywords: Reactive fluids, Couette Flow, variable viscosity, hydromagnetic and modified Adomian decomposition method (mADM).
Integration of geophysics and remote sensing techniques in mapping zones mineralised with disseminated gold and sulphide minerals in Lolgorien, Narok County, Kenya
Authors: Ombiro Sammy O , Olatunji Akinade S , Mathu Eliud M , Ajayi Taiwo R 
Published: July 2021

Even though ground geophysical surveys (especially Induced polarization and resistivity) are applied in mineral exploration, their effectiveness in identification of mineralised zones is often enhanced by integrating other mineral exploration techniques such as remote sensing and geological investigations. Integrating different techniques helps in reducing uncertainty that is often associated with mineral exploration. The methods being integrated also depend on characteristics of mineralisation and those of host rock. In this study, geophysical survey methods (induced polarization and resistivity) were integrated with remote sensing and geological methods to delineate mineralised zones in Lolgorien beyond reasonable doubt. By integrating these methods, it was found that Lolgorien’s gold and sulphide minerals (disseminated minerals) are hosted in massive quartz veins and auriferous quartz veins hosted in Banded Iron Formations. It was also found that this mineralisation was controlled by faults which mainly trend in two directions (NW-SE) and (NE-SW).

Modelos y aserción empírica: el modelo de doble hélice para la concepción semántica de la ciencia
Authors: O’Lery María de las Mercedes 
Published: July 2021

La propuesta del presente artículo es poner en comparación el modo de entender los modelos y la relación de éstos con el mundo para dos versiones dentro de la familia semanticista como lo son el realismo constructivo y la concepción estructuralista de las teorías científicas. Para exponer las particularidades de estos dos enfoques, se considerará el caso particular del denominado modelo de doble hélice propuesto por primera vez por James D. Watson y Francis H. C. Crick (Watson & Crick 1953a). El objetivo de este trabajo es modesto en la medida en que simplemente se intenta subrayar las diferencias entre las dos concepciones antes mencionadas a partir de considerar el tratamiento que cada uno de estos enfoques hace del modelo de doble hélice y, en el mejor de los casos, posibilitar un entendimiento más preciso de los elementos que cada uno de ellos proponen para el análisis de las teorías.

IntroductionOxidative stress is one of many factors suspected to promote antinuclear autoantibody (ANA) formation. Reactive oxygen species can induce changes in the antigenic structure of macromolecules, causing the immune system to treat them as “neo-antigens” and start production of autoantibodies. This study was designed to evaluate the relationship between oxidative stress markers, lifestyle factors and the detection of ANA.Material and methodsWe examined measures of oxidative stress indices of free-radical damage to lipids and proteins, such as total oxidant status (TOS), concentration of protein thiol groups (PSH), and malondialdehyde (MDA), activity of superoxide dismutase (SOD) in 1731 serum samples. The parameters of the non-enzymatic antioxidant system, such as total antioxidant status (TAS) and uric acid (UA) concentration, were also measured and the oxidative stress index (OSI-index) was calculated. All samples were tested for the presence of ANA using an indirect immunofluorescence assay (IIFA).ResultsThe presence of ANA in women was associated with lower physical activity (p = 0.036), less frequent smoking (p = 0.007) and drinking of alcohol (p = 0.024) accompanied by significant changes in SOD isoenzymes activity (p < 0.001) and a higher uric acid (UA) concentration (p < 0.001). In ANA positive males we observed lower concentrations of PSH (p = 0.046) and increased concentrations of MDA (p = 0.047).ConclusionsThe results indicate that local oxidative stress may be associated with increased probability of ANA formation in a sex-specific manner.
