Implementation of a Referral Scheme to Text Messaging Programs for Physical Activity and Healthy Eating in Underserved Hispanics
Authors: Portacio Francia G. , Corvalan Deborah , Stoutenberg Mark 
Published: February 2021

ABSTRACT
Hispanics share a disproportionate burden of several of the nation’s leading chronic diseases caused by poor lifestyle habits, such as a lack of physical activity and unhealthy eating. Interventions that include text messaging have shown the ability to positively affect health behaviors. This study examined the implementation of a referral scheme connecting Hispanic patients attending a community health clinic to text messaging programs encouraging health behavior change. A mixed methods approach was used to evaluate the implementation of the referral scheme. Assessments included tracking referral rates patient enrollment, as well as semistructured interviews conducted to identify barriers and facilitators experienced by health care providers. During the 2-month referral period, five health care providers referred 26 (8.9%) of the 291 eligible patients. Of these patients, only one self-enrolled in the text messaging program (3.9% of referred patients), with an additional 11 patients (42.3% of referred patients) enrolling after follow-up from an intern at the clinic. In-depth interviews with clinic administrators and providers, conducted at the end of the referral period, revealed four overarching barriers to the text messaging referral scheme: a lack of time during patient visit, limited resources and personnel, a lack of communication between administrators and health care providers, and an inefficient technology system. Addressing these barriers using alternative implementation strategies may lead to increased levels of health care provider adoption and patient enrollment in text messaging programs. Information from this study can inform areas of improvement in better linking underserved Hispanic patients to available resources for lifestyle modification.

ABSTRACT
Physical inactivity and sedentary behaviors are major contributors to chronic diseases and premature mortality. Although the benefits of physical activity have been documented, no study has systematically evaluated the feasibility and satisfaction of different physical activity routines designed for workplace settings. Therefore, the objectives of this research were to develop and evaluate six different types of 15-min physical activity routines. Based on pilot testing, we developed six different physical activity routines designed for the 15-min break during the workday, and 12 dimensions were used to evaluate each routine. The dimensions were as follows: appropriateness of work attire, benefit, challenge, complexity, confidence, effort (i.e., physical), embarrassment, enjoyment, fatigue, flexibility, likability, and sweat (i.e., perspiration). Before completing the ratings, participants received definitions of each dimension. Ninety-four full-time employees participated in six routines (i.e., aerobic dance, ballet, Booster Break, circuit training, muscle strengthening, and yoga) and rated their experiences using a 5-point Likert scale immediately after each session. All routines received some favorable ratings and seemed acceptable as a workplace activity. Circuit training and aerobic dance ranked highest on challenge, complexity, effort (i.e., physical), embarrassment, fatigue, and sweat, and low on work attire appropriateness. Booster Break ranked relatively high on benefit, confidence, likability, and work attire appropriateness; moderate on fatigue; and low on sweat and embarrassment. Circuit training and aerobic dance routines were the most challenging and appropriate for workforces with employees who are physically active and/or prefer challenges. For workforces with a diversity of preferences, abilities, or new to physical activity routines, the Booster Break is recommended because it was rated favorably on all dimensions. Future research is recommended to replicate these findings and improve the implementation effectiveness of work break routines.

Survey of traditional medicinal plants used to treat human ailments by the rural community of Bahir Dar City Administration was conducted from November 23, 2017 to May 30, 2018 with the aim of identifying and documenting plants and the associated knowledge used to treat humans. We collected data from six study sites using semi-structured interview, field observation and group discussion. Data analyses were made using preference ranking, direct matrix ranking and fidelity level index. A total of 77 medicinal plants were identified. The majority of plants (58.4%) are harvested from the wild. The largest number of plants were herbs (42.6%) followed by shrubs (32.6%). The most frequently used plant parts in human disease treatments are leaves (54%) followed by roots (18%). Most remedies are prepared by pounding and mixing (concoction) (36%). The remedial administration was mostly oral (51%) followed by dermal (31%). Allium sativum and Ocimum lamiifolium are frequently used. The community in the study area uses considerable diversity of plant species for maintaining their health care system. Nonetheless, conservation for those plants whose roots are harvested is necessary.

Authors: Murasheva Svetlana V. 
Published: February 2021

The urgency of the problem of studying the tension and conflict of interethnic interaction in the modern world is caused by the prevalence of negative opinions and stereotypical attitudes in society about persons belonging to ethnic groups different from Russian, the rapidly growing alienation of nations, the injustice of the administrative and territorial hierarchy of peoples, facts of ethnophobia and xenophobia. The ethnic component is becoming key and decisive in the social and political life of our country and causes inter-ethnic tensions and conflicts. At the current stage of development of social relations, there is an urgent need to develop and further introduce a system of prevention and resolution of inter-ethnic conflicts, which would be based on the Concept of State National Policy. Consolidation of society in order to solve national problems should be identified as a priority in the Concept of State National Policy. Due to these circumstances, research into the tensions and conflicts of inter-ethnic interaction has conceptual and practical significance, attracts the close attention of researchers from various fields of scientific knowledge and encourages them to develop and implement effective ways of preventing and settling conflicts of this type.
The aim of the article was to present the results of the study of interethnic tensions and conflicts in the modern world. An important place is given to the impact of interethnic conflicts on the development of social relations. The scientific novelty of the provisions proposed in the article is the study of the peculiarities of interethnic interaction and conflicts. Practical importance lies in the possibility of using the findings of the article to develop programmes for preventing and settling inter-ethnic conflicts.

Abstract
Salt stress is one of the important adverse conditions affecting bacterium growth. How bacteria isolated from greenhouse soil cope with salt stress and regulate the genes responsible for salt tolerance are still unclear. We conducted RNA transcriptome profiling of genes contributing to the salt tolerance of a Bacillus sp. strain (“SX4”) obtained from salinized soil. Results showed that NaCl effectively regulated the growth of “SX4” in terms of cell length and colony-forming unit number decrease. A total of 121 upregulated and 346 downregulated genes were detected under salt stress with reference to the control. The largest numbers of differential expression genes were 17 in carbon metabolism, 13 in the biosynthesis of amino acids, 10 in a two-component system, and 10 in ABC transporter pathways for adapting to salt stress. Our data revealed that cation, electron and transmembrane transport, and catalytic activity play important roles in the resistance of bacterial cells to salt ions. Single-nucleotide polymorphism and the mutation of base pair T:A to C:G play potential roles in the adaptation of “SX4” to high NaCl concentrations. The findings from this study provide new insights into the molecular mechanisms of strain “SX4” and will be helpful in promoting the application of salt-tolerant bacteria.

Abstract
Storage of wastes leads to severe problems of water pollution and neighboring matrices due to the infiltration of landfill leachate. Uncontrolled landfill and waste storage can lead to groundwater pollution, which can lead to serious health problems for the living. Engineered barriers can be a solution to these pollution problems. The purpose of this study was to develop novel composite materials – clay-based, activated carbon, cement, and PVA polymer. These composites were intended for the containment of waste in landfill. The clay (70–80%) and activated carbon (5–15%) contents were varied to obtain three different geomaterials – GM1, GM2, and GM3. In the preparation of GM3, the content of activated carbon used was higher than for GM1 and GM2, paracetamol removal capacity tested by adsorption, experiments were influenced by parameters such as the adsorbent mass, the initial solute concentration, contact time, temperature, and pH effect. The parameter of initial paracetamol concentrations was studied using a range of 50, 100, and 150 mg L−1. For a GM3 mass of 80 mg, the adsorbed amount is 14.67 mg g−1, and the contact time is 180 minutes. This study revealed that composites are efficient for the treatment of landfill leachates.

Published: February 2021

Abstract
Mango stem bark extracts (MSBE) have been used as bioactive ingredients for nutraceutical, cosmeceutical, and pharmaceutical formulations due to their antioxidant, anti-inflammatory, and analgesic effects. We performed the MSBE preparative column liquid chromatography, which led to the resolution and identification by GC-MS of 64 volatile compounds: 7 hydrocarbons, 3 alcohols, 1 ether, 3 aldehydes/ketones, 7 phenols, 20 terpenoids (hydrocarbons and oxygenated derivatives), 9 steroids, 4 nitrogen compounds, and 1 sulphur compound. Major components were β-elemene, α-guaiene, aromadendrene, hinesol, 1-octadecene, β-eudesmol, methyl linoleate, juniper camphor, hinesol, 9-methyl (3β,5α)-androstan-3-ol, γ-sitosterol, β-chamigrene, 2,5-dihydroxymethyl-phenetylalcohol, N-phenyl-2-naphtaleneamine, and several phenolic compounds. The analysis of MSBE, Haden variety, by GC-MS is reported for the first time, which gives an approach to understand the possible synergistic effect of volatile compounds on its antioxidant, analgesic, and anti-inflammatory effects. The identification of relevant bioactive volatile components from MSBE extracts, mainly terpenes from the eudesmane family, will contribute to correlate its chemical composition to previous determined pharmacological effects.

Published: February 2021

Abstract
A human intoxication incident attributed to pesticide abuse was investigated using cutting-edge analytical methodologies. An LC-ESI-MS/MS method, based on a hybrid solid-phase extraction protocol (hybrid-SPE), was applied for the detection and quantification of several pesticides and metabolites in human biological fluids. Concomitantly, an UHPLC-HRMS method was applied to investigate potential metabolites, assisted by a complementary GC-MS method to elucidate the presence of plausible pesticides co-formulants. The LC-ESI-MS/MS method exhibited acceptable mean recoveries at the lower limit of quantification (LLOQ) and three additional levels, varying from 85 to 106% for all analytes and matrices. In serum, urine, and gastric fluid samples, the suspect compounds, namely chlorpyrifos and myclobutanil, predominated. Gastric fluid samples contained the highest concentrations of chlorpyrifos (39,800 ng/mL) and myclobutanil (18,800 ng/mL), while the neonicotinoid imidacloprid was also quantified, below 30 ng/mL. Notwithstanding, the UHPLC-HRMS analysis unveiled several metabolites of chlorpyrifos and myclobutanil. In parallel, GC-MS analysis, corroborated the presence of several co-formulants in gastric fluid samples, exemplified by m- and o-xylene, and cyclohexanone. Overall, three analytical methods were implemented to elucidate the chemical causality of a human intoxication incident. The presence of suspected active substances, one additional, and several metabolites and co-formulants were documented.

Abstract
Different phytochemicals from various plant species exhibit promising medicinal properties against cancer. Juniperus phoenicea is a plant species that has been found to present medicinal properties. Herein, crude extract and fractions of J. phoenicea were examined to determine its anticancer properties against several cancer cells. The active fraction was chosen to assess its activity on cell cycle progression and apoptosis induction by annexin and propidium iodide (PI) biomarkers. Further, phytochemical screening for possible contents of active fraction using gas chromatography–mass spectrometry (GC-MS) analysis was conducted. It was demonstrated that cell proliferation was suppressed, and the MCF-7 cell line was the most sensitive to J. phoenicea chloroform fraction (JPCF), with the IC50 values of 24.5 μg/mL. The anti-proliferation activity of JPCF in MCF-7 cells was linked to the aggregation of cells in the G1 phase, increases in early and late apoptosis as well as necrotic cell death. Contents analysis of JPCF using GC-MS analysis identified 3-methyl-5-(2′,6′,6′-trimethylcyclohex-1′-enyl)-1-penten-3-ol (16.5%), methyl 8-oxooctanoate (15.61%), cubenol (13.48%), and 7-oxabicyclo [2.2.1] heptane (12.14%) as major constituents. Our present study provides clear evidence that J. phoenicea can inhibit cell proliferation, trigger cell cycle arrest, and induce apoptosis in tested cancer cells.
Technical analysis of the renovation works of the wooden palace floors
Authors: Kafel Katarzyna , Juszczyk Michał , Buda Piotr 
Published: February 2021

AbstractThe paper presents technical analysis of two aspects of palace wooden floors – the first example describes renovation works in a historical building, while the second presents assembly of a new floor in the contemporary building. In case of both examples technology of construction works is discussed in details with a special focus on issues specific for wooden palace floors. The authors paid special attention to introduce problems that occurred during the performance of the works. Both cases are compared. The restoration of the antique mosaic is significantly different from the implementation of the palace mosaic (tile) from bottom-up. Restoration works required more effort, mostly due to the fact that the antique mosaic floor experienced many years of use and needed specific repairs. On the other hand making the palace mosaic from scratch is burdened with a much smaller number of unforeseen situations. Due to the high aesthetic requirements, decorative functions and unique character of both discussed examples of flooring works, each of the tasks was labour-consuming and needed highly specialized works.

Authors: Andres Nelson S. 
Published: February 2021

Abstract
This study discusses a solar-powered water pump system with 3D printed impeller which was developed to serve as water irrigation to small and medium farms in Bataan, Philippines. One kW solar PV system was used to power an electric motor that drives the centrifugal pump with impeller. In order to minimize the power consumption of the pump, the material of its impeller was changed from brass to plastic using 3D printing technology. The water system was also made automatic so that the water pump will run and stop at the desired schedule of the farmer. Furthermore, in order to provide power at night, storage batteries which are enough to supply the load, were incorporated in the system. Through a series of testing, it is concluded that it is more economical to use a 3D printed plastic impeller than metal impeller in watering small and medium farms considering that there were appreciative changes observed in relation to their water output and power consumption.

Published: February 2021

Abstract
The effects of particle size on the apparent kinetics of carbothermal reduction process of phosphate rock were studied by non-isothermal thermogravimetric analyses. Phosphate rock of various particle size was reacted with coke and silica under high purity argon atmosphere. The apparent kinetic model and parameters of carbothermal reduction reaction of phosphate rock with different particle sizes were derived by combination of model-free (Flynn–Wall–Ozawa, Kissinger–Akahira–Sunose, Tang, Starink) and model-fitting (Coats-Redfern, Master-plots) methods. The results showed that the obtained apparent activation energy of reaction reduces from 371.74 kJ/mol to 321.11 kJ/mol as the particle size of phosphate rock decreasing from 100–150 μm to 38–48 μm. The reaction apparent kinetics was found to follow shrinking-core model and the conversion degree function equation is

Published: February 2021

Abstract
The article presents and assesses the shortcomings of the applicable provisions regarding the maintenance of the necessary distance behind the preceding vehicle in road traffic. We are exposed to accidents when using vehicles. The human factor contributes greatly to their occurrence. A problem analysis was carried out with proposed changes. The conclusions indicate the need for conducting training and clarification of the provisions in the applicable road traffic law. The introduction of new technical devices for determining the distance, in extreme situations, does not eliminate the danger of colliding with the preceding vehicle. In this respect, the regulations are imprecise, and the lack of knowledge of drivers is huge. The proposed actions relate to the area of active safety system of vehicles in road traffic.
Entrepreneurial Attitude and Intention in Higher Education Students: What Factors Matter?
Authors: Rodrigues Margarida , Silva Rui , Franco Mário 
Published: February 2021

Abstract
This study seeks to understand the main factors predicting the future entrepreneurial attitude and intention of higher education students. To do so, a questionnaire was sent to a sample of 508 students at a higher education institution (HEI) in the central region of Portugal. From a structural equation model, the results show that students’ entrepreneurial attitude is influenced positively, and with statistical significance, by Entrepreneurial Benefits, Entrepreneurial Passion, Psychological Cognition Factors and Religion Beliefs. On the other hand, the factors/dimensions of Self-Confidence and Creativity are found not to have a statistically significant influence on the Entrepreneurial Attitude of the students studied. In turn, entrepreneurial attitude was a direct and mediated predictor of students’ entrepreneurial intention. The results of the study can explain the influence of important factors on students’ entrepreneurial attitude and intention, presenting relevant challenges for HEIs to develop and provide more courses and programmes aimed at entrepreneurship. Such initiatives are a way to motivate students to be future entrepreneurs, raising business development and growth in the economy in general, and the country in particular. This study also makes an important contribution to the literature on higher education students’ attitude towards entrepreneurship and its influence on their future entrepreneurial intention. People with a strong entrepreneurial attitude and intention are needed to allow development, growth and innovation in the business sector. These actions can motivate students to be future entrepreneurs raising the business development and growth of the economy in general.
