The work is devoted to the study of the effect of various compounds on the stability of electroless copper plating solution containing Trilon B. as a chelating agent. The stability of electroless copper plating solutions was estimated by the accelerated method as the time before the start of intensive decomposition of the solution after the introduction of 0.15 ml of colloidal palladium activator solution heated to 75 °C in 250 ml. As stabilizers, both known, currently used, and newly selected compounds were investigated. Sulfur- and/or nitrogen-containing organic and inorganic compounds such as: sodium diethyldithiocarbamate, 2,2’–dipyridyl, thiosemicarbazide, potassium hexacyanoferrate (III), potassium hexacyanoferrate (II), thiourea, thioglycolic acid, dimethylglyoxime, potassium rhodanide in concentrations in the range of 1 - 50 μmol/l were among the first studied. It is shown that when the stabilizers are contained in the solution at the optimal concentrations set (for each compound), solutions containing sodium diethyldithiocarbamate, thioglycolic acid, thiosemicarbazide, thiourea (in descending order of stabilizing action), i.e. compounds containing a sulfur-carbon bond, have the greatest stability. With this in mind, other sulfur-containing compounds, including heterocyclic ones, were selected and studied as stabilizers: α-lipoic acid, thiamine chloride, methyl orange, nitroso-p-salt, methylene blue and SPADNS (sodium salt of 2-(psulfophenylazo)-1,8- dihydroxynaphthalene-3,6- disulfonic acids). In addition, nitrogen-containing compounds that were not previously used in electroless copper plating solutions as stabilizers were also studied: nicotine, pyridoxine, Janus Green B (8-(4-dimethylaminophenyl) diazenyl-N, N-diethyl-10-phenylphenazine-10-ium-2-amine chloride), nigrosine, however. Solutions of electroless copper plating in the presence of these compounds did not show high stability. It has been established that the most effective, comparable in effect to the stabilizers currently used, are α-lipoic acid and thiamine chloride. The advantages of the latter are their availability and low toxicity.

Published: July 2024

Nano silver has long been known as a highly effective disinfectant, capable of limiting the growth and eliminating many types of mold and bacteria. Nano silver can be synthesized by many different methods, depending on the purpose and requirements of use. Nano silver can be dispersed in solution or carried onto carriers for different applications. However, in solution, silver nanoparticles often tend to bind together, reducing antibacterial activity. In order to promote the antibacterial ability of nano silver and be able to recover and reuse many times, as well as to be able to disperse well into different materials, nano silver is often put on the carriers. In this study, nanosilver was synthesized on the surface of a zeolite by simple methods such as chemical reduction with NaBH4, N2H4 or thermal reduction at 350 °C. Ag+ ions are adsorbed onto 4A zeolite by ion exchange mechanism, then reduced by different methods. The materials were morphologically analyzed by XRD, SEM, EDX methods. Results showed that the method of reducing Ag+ to Ag0 on zeolite surface by chemical agent produce more evenly distributed silver nano-sized particles than the thermal reduction method. The silver content on the zeolite surface of the hydrazine reduction method is about 3 times higher than that of the sodium borohydride reduction method. The highest content of silver nanocarrying to zeolite. Zeolite bearing nano silver has the ability to disinfect against E.Coli with a concentration of ≥ 5 mg/ml. The Ag02/Z sample reducing Ag+ to Ag0 by Hydrazin has the best antibacterial ability against E.coli compared with the remaining samples when the diameter of the sterile ring at the concentration of 20 mg/ml is 9 mm.

INTERACTION OF IONIC LIQUIDS BASED ON BIS(TRIFLUOROMETHYLSULFONIL)IMIDE ANION WITH HALLOYSITE NANOTUBES ACCORDING TO FT-IR SPECTROSCOPY
Authors: Ramenskaya Lyudmila M. , Grishina Elena P. , Kudryakova Nadezhda O.
Published: July 2024

In this work, FT-IR spectroscopy was used to study the interactions in ionogels of the composition х[X]+[TFSI]−/(100 - x)НNT, where [TFSI]– is the bis(trifluoromethylsulfonyl)imide anion, the cation [X]+ = [BMPip]+ (1-butyl-1-methylpiperidinium), [BMPyr]+ (1-butyl-1-methylpyrrolidinium), and [BMIm]+ (1-butyl-3-methylimidazolium), HNT are halloysite nanotubes, х = (55.2±0.5) wt.%. A comparison of the spectra of the starting compounds and the resulting ionogels showed that the characteristic frequency of the stretching vibrations of OH bonds of adsorbed water molecules, observed in the spectra of pure halloysite, practically vanishes in the spectra of ionogel sts. The stretching vibrations of the C-H bond atoms of the cation, ν(CH), and the stretching vibrations of the C-F bond atoms of the CF3 group of the anion, ν(CF3), in the spectra of limited ionic liquids are shifted to the high frequency region by 1-3 cm-1. The ratio of the intensities of the asymmetric bending vibrations of the S=O bond atoms of the SO2 group, I(δasopSO2)/I(δasipSO2), which correspond to two different conformational isomers of the anion, increases by (15-19)%. As a result, it was found that the H2O molecules of halloysite are replaced by molecules of the ionic liquid due to the electrostatic interaction of the cation with the negatively charged outer siloxane (–Si–O–Si–) surface of the nanotubes and hydrogen bonds (CH···OSi), and due to the electrostatic interaction of the anion with a positively charged internal aluminol (–Al–OH) surface and hydrogen bonds (CF···HO–Al, SO···HO–Al). The restriction of the ionic liquid in the internal cavity of the HNT causes a conformational rearrangement of the [TFSI]− anion. The results obtained are of fundamental importance, make a certain contribution to understanding the effects in ionogels based on ionic liquids and nanoporous natural minerals, and can be used to develop quasi-solid electrolytes in the production of various electrochemical devices.

El presente artículo expone los resultados de una revisión sistemática sobre el tema de tromboprofilaxis en pacientes hospitalizados. Se realizó una revisión de literatura científica de más de 15 artículos de alto nivel de evidencia. Las investigaciones destacan que el tromboembolismo venoso sigue siendo una condición de riesgo para los pacientes hospitalizados, quienes la sufren en una relación de 100 veces más que los pacientes no hospitalizados. En todo el mundo las tasas de riesgo son similares, y se incrementan en personas con sobrepeso u obesidad, adultos mayores, fumadores, y personas con antecedentes genéticos de propensión a coagulopatía. Los estudios reportan que a pesar de suficientes herramientas para la aplicación de tromboprofilaxis, aún se mantienen necesidades insatisfechas con respecto a la aplicación oportuna de este tratamiento preventivo. Los anticoagulantes y las técnicas mecánicas siguen siendo la principal forma de tromboprofilaxis. Se está innovando en el campo, con la prueba de nuevos fármacos y nuevas tecnologías físicas como sistemas de compresión neumática, medias diseñadas a medidas y estimuladores eléctricos neuromusculares.

Authors: Saavedra Silva
Published: July 2024

School is a space where students learn to coexist with others. However, school violence is a common problem in educational institutions, manifested in behaviors such as abuse, bullying, mistreatment, and humiliation. Governments have implemented public policies to mitigate this problem, but it is necessary to evaluate their purpose and relevance.This systematic review aims to identify and understand the main approaches and characteristics of public policies on school coexistence in Latin America. A search was conducted in eight databases and two search engines using a systematic review methodology based on the PRISMA 2020 statement guidelines. The results showed three main approaches to the development of these policies: punitive, formative, and managerialist, each linked to a psychological perspective. The reviewed studies showed positive impacts on the perception of school coexistence, but further research is needed, as there are few studies and they are limited in scope. The literature review was conducted with publications between 2017 and 2023.

Published: July 2024

This descriptive-qualitative research determined the level of knowledge and integration of the DepEd Core Values of Physics teachers and the challenges which the teachers encounter during the integration of the DepEd Core Values in teaching Physics, as well as the DepEd Core Values reflected in the self-learning modules. The sixty-five (65) JHS Physics teachers from the Schools Division of Ilocos Norte, who were chosen via total enumeration, were the participants of the study. The main tools used in gathering data were the adapted survey questionnaire, a researcher-made tally sheet, and an interview guide. The data gathered were statistically analysed using mean, frequency, and rank. Results show that the teachers are highly knowledgeable in the application of the DepEd Core Values in teaching Physics. Meanwhile, results also show that the teachers are advanced in integrating the DepEd Core Values in teaching Physics. However, there is a limited frequency of 15 DepEd Core Values reflected in the SLMs of JHS Physics, which affect the teachers’ integration of the DepEd Core Values in their lesson. Moreover, the teachers face challenges in the integration of the DepEd Core Values it is because teaching Physics as the subject focuses on content and skills development. Values integration is difficult to implement and time consuming, and there is limited integration of the DepEd Core Values in the prescribed SLMs.

Authors: Momanyi Evans Motari , Ng’eno Emily , Kiplang'at Joseph
Published: July 2024

With the growing size and complexity of library collections coupled with the explosion of medical information in diverse formats, medical students require competencies in identifying, locating, retrieving, evaluating, synthesizing, and effectively utilizing information. There is a need, therefore, for medical students to acquire Information Literacy Skills (ILS) to master content, extend their investigations, and become more self-directed and life-long learners. The objectives of the study were to: examine the ILS curricula in place to facilitate the delivery of ILS among medical undergraduate students at Moi University and the University of Nairobi, and to assess the methods used to enhance the delivery of ILS among medical undergraduate students at Moi University and University of Nairobi. A pragmatic research paradigm with a mixed-methods approach was employed in the study. The study adopted a descriptive survey design applied within a multiple case study, combining concurrent triangulation in data collection and analysis. The target population was 685 students comprising 6th-year medicine, 5th-year dentistry, and 4th-year nursing students, and 182 lecturers. A combination of stratified simple random and purposive sampling techniques was employed to obtain 353 medical undergraduate students, 62 lecturers in medicine, dentistry, and nursing specializations, 2 university librarians, 2 heads of medical librarians, and 6 heads of departments. Data was collected using questionnaires and interview schedules. Quantitative data was analyzed using descriptive statistics and presented using frequency distribution tables and bar charts while qualitative data was analyzed thematically based on the objectives and research questions and presented as narrative. The findings revealed that although ILS curriculum and policy were available, there was little implementation and accountability, indicating that the ILS curriculum and policy had not been reviewed to incorporate contemporary ILS. The study concluded that students had not acquired sufficient ILS competencies due to a combination of factors such as poor perception of ILS, low pedagogical expertise among ILS trainers, and absence of sustainable ICT infrastructure to facilitate the acquisition and utilization of fourth ICT revolutions’ competencies. The study recommends that institutions of higher learning should introduce four ILS credit-scored course units.

Despite the impression that can be gained from most of the standard textbooks, Dirac, Klein-Gordon and other wave equations do not constitute the basis of quantum field theory. In this article I attempt to show how it should be formulated properly and discuss some of its aspects which usually are presented unsatisfactorily.The aim of the text is to cause the change in the way quantum field theory is taught.The text is split into three parts. In this part 3 (the last one) I discuss the LSZ prescription which allows to extract S-matrix elements without making the usual, very restrictive assumptions and advantages and weak sides of formulating quantum field theory with the help of path integrals.

Breast cancer is a malignant disease that most commonly attacks women. One pharmacological therapy for breast cancer is chemotherapy, but this treatment can cause anxiety due to the side effects it causes. Non-pharmacological treatment is really needed, one of which is Progressive Muscle Relaxation (PMR) which can reduce anxiety. The aim of the research was to determine the effectiveness of Progressive Muscle Relaxation (PMR) on anxiety in breast cancer patients. Sampling used purposive sampling technique. The total sample was 30 respondents (15 respondents were given PMR therapy) and (15 respondents were given deep breathing). Anxiety measurement uses the State Trait Anxiety Inventory (STAI) questionnaire. The test used to correlate PMR with disease duration is the Pearson test. Differences in cancer stage and mean anxiety score independent t-test. One-way anova test chemotherapy cycle. Meanwhile, the difference between pre and post PMR and control used the paired t-test. The results of the study showed no significant values for the duration of suffering from total anxiety p = 0.476, state anxiety p = 0.424, trait anxiety p = 0.464. At stage 3 it showed significant values for total anxiety p = 0.004, state anxiety p = 0.003, trait anxiety p = 0.018, at stage 4 total anxiety p = 0.009, state anxiety p = 0.009, trait anxiety p = 0.020. The chemotherapy cycle was not significant for total anxiety p = 0.084, and state anxiety p = 0.177, while trait anxiety showed a significant value of p = 0.026. Pre and post PMR showed significant values for total anxiety, state anxiety, and trait anxiety p = 0.001.

A study was conducted at the Lay - Joy Fish Farm, Billiri, Gombe State Nigeria to evaluate the carcass proximate composition of Clarias gariepinus fingerlings fed different levels of Maca root powder as Phyto - additive. Five (5) isonitrogenous (40% crude protein) and isocaloric (1,732kcal kg-1 gross energy) diets were formulated, where Maca root powder in form of Phyto - additive was incorporated at 0.0g/100g (TM0), 0.25g/100g (TM1), 0.5g/100g (TM2), 0.75g/100g (TM3) and 1.0g/100g (TM4) inclusion levels, diet without Maca root powder (TM0), served as the control diet. The formulated diets were fed to Clarias gariepinus fingerlings (n = 300, 10.0±0.00g) in fifteen (15) rectangular white plastic tanks (n = 20) at a fixed feeding rate of 3% body weight twice daily between the hours of 8:00 - 9:00 am and 4:00 - 5:00 pm at regular interval and adjusted after every two (2) weeks of sampling for a period of twelve (12) weeks. Proximate analysis was carried out on a sample of the Clarias gariepinus fingerlings at the beginning of the experiment, at the end of the experiment three (3) Clarias gariepinus from each treatment were sacrificed and the carcass subjected to proximate analysis. Data obtained were analysed using one-way analysis of variance (ANOVA) at P = 0.05. Carcass crude protein value was highest in fish fed diet TM3 (72.00±1.32%) and least (67.80±1.96%) in the fish fed the control diet (TM0), carcass crude lipid value was highest in fish fed diet TM3 (14.70±1.19%) and least (14.07±2.45%) in the fish fed a control diet (TM0), while the carcass crude fibre value was highest in fish fed control diet (TM0) (0.47±0.03%) and least (0.36±0.07%) in the fish fed  diet TM3, carcass moisture value was highest in fish fed diet TM2 (1.64±0.07%) and least (1.41±0.04%) in the fish fed diet TM3, carcass ash value was highest in fish fed diet TM2 (11.15±2.03%) and least (10.00±1.67%) in the fish fed diet TM3 and the carcass nitrogen free extract value was highest in fish fed control diet (TM0) (5.50±0.76%) and least (1.53±0.73%) in the fish fed  diet TM3. The incorporation of Maca root powder as Phyto-additive into the diet of Clarias gariepinus had no effect on the carcass proximate quality. Although there was a significant difference (p<0.05) in the carcass proximate composition of the Clarias gariepinus, no clear trends were noticed. Feeding Clarias gariepinus fingerlings with Maca root powder at 0.75g/100g feed inclusion level as Phyto - additive is recommended. However, further research should be carried out on other Phyto - additives on their efficacy in determining the carcass proximate composition of Clarias gariepinus.

The phenomenon of Primary School children is more fun to  play  games  than  reading  and  writing  books.  The  literacy  capability  assessment  of  students  in  Indonesia  by  International  Association  of  Educational  (IAE)  and  Organization  for  Economic  Co-operation  and  Development (OECD) from 2011-2015 still below the everage score as  well  as  the  country  ranking.  In  2015  the  Ministry  of  Education  and  Culture  socializes  the  massive  School  Literacy  Movement  named  Gerakan  Literasi  Sekolah  (GLS).  However  in  fact,  the  majority  of Primary Schools in Indonesia is less sensitive and cannot implement the program well in school. In order to solve the problem, the principal and teachers in the Primary School needs to apply the Continous Literacy Program  for  All  (CLP  FALL)  consistently  and  measurably.  By  using Watson-Guthrie’s behaviorism theory and Piaget’s cognitive theory this program should be applied and developed. The program includes three pahases;  1)  planning,  2)  implementation,  and  3)  evaluation  and development.  The  gradual  implementation  includes  daily,  weekly, monthly,  semester,  and  annual  activities  involving  all  academic members.
Litigios relativos a la inclusión en ficheros de morosos. Jurisprudencia actual
Authors: Blázquez Martín Raquel
Published: July 2024

La incursión de la litigación en masa en el ámbito de la tutela civil de los derechos fundamentales, que tan impensable nos hubiera parecido hace unos pocos años, se está produciendo de la mano de la inclusión de datos personales en los popularmente conocidos como ficheros de morosos. Este fenómeno ha provocado la creación de una jurisprudencia muy prolija. Los apartados que siguen responden al intento de proporcionar una guía útil que sistematice esa jurisprudencia y permita rentabilizar el trabajo adicional que exige la litigación en masa. Se trata, en suma, de ofrecer las pistas necesarias para que nos cueste menos esfuerzo identificar los matices de cada caso y para saber qué posibilidades de decisión tenemos ante las singularidades de cada cuestión controvertida.

Published: July 2024

Senna is a highly-producing Leguminosae herb known as a ringworm plant. Antioxidants protect the body against reactive oxygen species-induced oxidative damage, which is linked to cardiovascular disease and cancer. Naturally occurring plant antioxidants are being considered as preventive medicine. Escherichia coli, Staphylococcus aurteus, Enterococcus faecalis, and Bacillus subtilis were examined for Senna alata extract secondary metabolites, antioxidant, and antibacterial activity. The plant leaf was phytochemically examined for alkaloids, tannins, general glycosides, steroids, and terpenoids. A quantitative study of leaf extract secondary metabolites was done. Results showed that alkaloids, tannins, steroids, and terpenoids had concentrations of 8.5±2.0mg/100g, 12.5±1.0mg/100g, 17.0±2.0mg/100g, 11.5±3.0mg/100g, and 16.0±3.1mg/100g, respectively. The study discovered that increasing the quantities of leaf extract directly enhanced the scavenging action of DPPH (2, 2-diphenyl-1-1-picrylhydrazyl). The antioxidant activity of the leaf extract was inferior to that of ascorbic acid. The test organisms were susceptible to the plant extract due to the presence of zones of inhibition. At the lowest concentration, the Senna alata leaf extract combined with Ethanol exhibited the highest level of inhibition against Escherichia coli and Staphylococcus aureus. The findings of this study suggest that the chemical compounds found in Senna alata leaf extract will have potential applications in chemotherapy.
The value of organic agriculture beyond contemporary food sufficiency in the developing world
Authors: Mkenda Prisila Andrea , Ligate Elly Joseph , Mkonda Msafiri Yusuph
Published: July 2024

Understanding the value of organic agriculture beyond contemporary food sufficiency is crucial in addressing sustainable agriculture and the welfare of the community. Yet, economic analysis of agricultural output usually focuses on crop yield rather than other intangible values related to environmental health, which mainly encompass human health and the environment. The non-marketable value of the ecosystem services in organic agriculture is always higher than in conventional agriculture. When the non-market value is considered during yield assessment, the difference in crop yield between organic and conventional agriculture may be insignificant or even higher for organic. This paper aims to give a gritty overview of the intangible values of organic agriculture in comparison with conventional agriculture to account for other environmental and health benefits associated with organic farming. This is crucial because productive agroecosystems for sustainable development should be able to meet the needs of the present generation without compromising the ability of the future generation to meet their needs. It has been revealed that the application of ecological principles under organic agriculture brings several environmental and socio-economic benefits.  Therefore, there is a need to explore some insights into the values of organic agriculture beyond the contemporary food sufficiency which are usually given less attention during economic analysis, for increased understanding and adoption of this kind of farming to harness the associated potentials.

Published: July 2024

A field survey was conducted from March 2021 to October 2021 to identify major constraints in the Indian small cardamom sector.  A micro-macro approach was followed in the study using both primary and secondary data. The primary data from random sample farmers and market intermediaries were collected from Kerala and Tamil Nadu producing areas. In total, 180 farmers, 12 auctioneers, 50 dealers (30 village traders and 20 dealers), and five exporters were interviewed; thus, the primary data were collected. The secondary data on arrivals, prices, and cardamom trade were collected from different national and international sources. Several important constraints related to production, marketing and auction, market price, international trade, cardamom value chain, pesticide residue, climate change, degradation of forests, and market deregulation have emerged from our analysis. All the constraints were thoroughly studied in depth, and appropriate interventions and policies were suggested to revive the small cardamom sector in India.

The structural equation model development of how mindfulness promotes employee creativity in the restaurant business
Authors: Ratasuk Akaraphun
Published: July 2024

This study examined whether mindfulness can promote restaurant employee creativity, which is crucial in achieving a business competitive edge and sustainable viability, and its mechanism through interpersonal trust and knowledge sharing based on the social capital theory. This study was carried out in Bangkok's full-service restaurant context. Data were collected from 414 restaurant employees, accounting for an 82.80% response rate. A partial least squares structural equation model (PLS-SEM) was used for data analysis, and the Sobel test and bootstrapping were used to test mediating effects. The results showed that mindfulness empirically promotes employee creativity (β = 0.093; p = 0.028).  Also, according to the PLS-SEM and Sobel test, confirmed by bootstrapping results, interpersonal trust (t = 3.216, p = 0.001) and knowledge sharing (t = 3.053, p = 0.002) can partially mediate the relationship. The results also revealed a positive partial mediation of knowledge sharing between interpersonal trust and employee creativity (t = 9.875, p < 0.001). These results contribute up-to-date and new knowledge in the related literature by supporting and advancing previous research, particularly the benefits of mindfulness, antecedents to employee creativity, and expansions to the social capital theory. This research implies that developing mindfulness in employees could play a beneficial role in improving their relationships with others, resulting in the promotion of their work creativity. In addition, the results provided valuable guidelines for restaurant management to promote employee creativity for sustainable business viability.
