Authors: Fidelis Iraci , Januário Graciele da Silva 
Published: November 2023

Entendemos que o ato de pesquisar é primordial no processo de aprendizagem e, principalmente, na construção de indivíduos autónomos e críticos. A compreensão acerca do uso adequado da estatística, propicia menores erros nos relatos dos resultados executados e na interpretação das suas conclusões. O que se observa hoje são análises de experimentos mal realizados e resultados erroneamente interpretados. O que justifica que o próprio aluno na construção do seu artigo, seja capaz de realizar as análises e interpretar os resultados. O projeto foi desenvolvido com duas estudantes do terceiro período do Curso Superior de Tecnologia em Aquicultura do Instituto Federal de Roraima. Este trabalho objetivou tornar os alunos conscientes da aplicação de delineamentos utilizados na experimentação agropecuária e suas aplicações, por meio de resolução de lista de exercícios e apresentar o sistema computacional SISVAR com aplicações diversas na análise estatística de experimentos, pela facilidade de acesso e utilização. As alunas foram capazes de a partir de dados obtidos de exemplos práticos: sugerir qual o melhor delineamento em cada exercícios, analisar os dados e ver se os mesmos seguiam as pressuposições para realizar a analise de variância, formular as hipóteses para validade do teste F, realizar a análise de variância e aplicar o teste F. A partir do teste F, foram capazes de realizar o estudo dos desdobramento e encontrar em cada exercício o melhor tratamento em função do estudo do teste Tukey ou em função do estudo de regressão. Concluímos que as alunas adquiriram a habilidade em interpretar, analisar e resolver a informação advinda dos dados coletados durante a execução da pesquisa e tornaram-nas conscientes dos diversos aspectos de aplicação de métodos estatísticos proposto no projeto.
ГЛИНЯНІ ВИРОБИ В ПОХОВАЛЬНИХ ПАМ’ЯТКАХ ДАВНЬОРУСЬКОГО ЧАСУ (за матеріалами археологічних досліджень кінця ХІХ – другої половини ХХ ст.)
Authors: Троцька Валентина 
Published: November 2023

Мета статті полягає в здійсненні аналізу праць археологів кінця ХІХ – другої половини ХХ ст., в яких досліджували глиняні вироби в похованнях давньоруського часу. Опрацьований матеріал дозволяє дійти висновків, що впродовж давньоруського часу існували два поховальні обряди – трупоспалення та трупопокладення небіжчиків. При обох видах поховань серед супровідного інвентарю знаходили різні типи глиняних виробів: горщики, глечики, миски, амфори, зооморфні та антропоморфні статуетки тощо. Наявність глиняних виробів у похованнях дослідники в першу чергу пов’язують із віруванням жителів у потойбічне життя, намаганням забезпечити покійного всім необхідним на тому світі, зокрема їжею та питвом, оскільки давньоруське населення вірило, що в потойбічні продовжується життя. Традиційною є думка, що в поховальній обрядовості речі, які клалися до могили, мали забезпечити потреби небіжчика після тілесної смерті. Вдалося дослідити місцезнаходження та різні способи покладання глиняних виробів у могилах під час кремації та інгумації померлих, як у дорослих так і дитячих похованнях.
Two new species of Scolopocryptops centipedes from southern Japan (Chilopoda: Scolopendromorpha: Scolopocryptopidae)
Authors: Jonishi Taro , Nakano Takafumi 
Published: November 2023

The blind centipede genus Scolopocryptops Newport, 1844 comprises two lineages: the “Asian/North American” group and the “Neotropical/Afrotropical” group. The former can be further split into two groups, a clade comprising Scolopocryptops elegans (Takakuwa, 1937) and Scolopocryptops curtus (Takakuwa, 1939), and a clade comprising all other “Asian/North American” species. Here, Scolopocryptops miyosii sp. nov. from Kyushu and Amami Island and Scolopocryptops brevisulcatus sp. nov. from Izena Island and Okinawa Island in southern Japan are described. The two new species have external features similar to S. elegans and S. curtus. They can be distinguished from most other “Asian/North American” Scolopocryptops by the absence of complete sulcus/sulci along the lateral margin of the cephalic plate and the presence of sternal longitudinal sulci. They can be distinguished from each other by several external features, such as the density of antennal setae and the shape of the anterior margin of the coxosternite. Phylogenetic analyses using nuclear and mitochondrial markers also support the monophyly of the four species, which form a clade sister to all other “Asian/North American” Scolopocryptops.
Electrospun Ag/Al2O3 fibers for removal of methylene blue
Authors:   , Waikasikarn Parom 
Published: November 2023

In this work, electrospun Ag/Al2O3 fibers were prepared by the sol–gel electrospinning methods in order to apply as sorbent and catalyst in photocatalytic reaction for removal of methylene blue. The electrospun Ag/Al2O3 fibers at various silver concentrations (2, 5 and 10%w/w) and different calcination temperatures (350 and 500 oC) were prepared. The electrospun Ag/Al2O3 fibers were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), UV-VIS spectroscopy, X-ray Diffraction Analysis (XRD) and nitrogen adsorption/desorption analysis. The phase of alumina in Ag/Al2O3 fibers was gamma-alumina phase and the average diameter of obtained fibers was 75 nm. The average diameters of silver particles in Ag/Al2O3 fibers ranged from 3 to 13 nm and were in the form of Ag0 and Ag2O. Then the electrospun Ag/Al2O3 fibers were applied for the removal of methylene blue in water. The removal efficiency of methylene blue by adsorption process was mainly from the host alumina which showed the percent removal of 54.8%. However, the calcined 10%w/w Ag/Al2O3 fibers at 350oC enhanced the removal efficiency of methylene blue by photocatalytic degradation approximately 2 times (% removal of methylene blue was 25% for Al2O3 and 48% for calcined 10%w/w Ag/Al2O3 fibers at 350oC). As a result, the Ag/Al2O3 fibers (calcined 10%w/w Ag/Al2O3 fibers at 350oC) exhibited the great effectiveness in the removal of methylene blue in water with 95.3% removal (47.3% by adsorption process and 48.0% by photocatalytic degradation). In addition, the electrospun Ag/Al2O3 fibers were easily collected and can be reused up to 3 times without the loss of photocatalytic degradation performance.
Fischer-Tropsch synthesis over cobalt supported on silica hollow sphere catalyst
Authors:   , Atchimarungsri Thachapan 
Published: November 2023

A propose of this work studied the silica hollow sphere (SHS) for a proper characteristic of support in the Fischer-Tropsch synthesis (FTS) because the normally main problem of FTS reaction was being produced the broader hydrocarbon products on a commercial catalyst. Nevertheless, the hollow sphere shape of SHS catalyst had a wall of the core catalyst for steric restriction of hydrocarbon propagation. The cobalt metals were loaded on the SHS by wetness impregnation method and used in the FTS. The SHS was synthesized through emulsion process with water/oil/water (W/O/W) that used the sodium silicate for silica source and NH4HCO3 for the mesopore generating in the SHS support. The proper SHS catalyst in FTS showed higher specific surface area more than 500 m2/g and less micropore, causing diffusion elimination and mass transfer inside the pore, which resulted in the enhanced CO conversion more than 90 percent, lower C12+, and the narrower hydrocarbon selectivity. Moreover, the study of the coated zeolite that was ZSM-5 type on the SHS catalyst was two methods, which were hydrothermal synthesis and steam-assisted crystallization (SAC) process. The results of both methods represented the increase of narrower hydrocarbon products, isoparaffins and olefins selectivity due to acid sites of the zeolite. However, these methods as the improved cobalt based over SHS catalyst had some problems such as the decomposing of the silica, removing of cobalt metals on the SHS support and uncovering of some zeolite over the SHS catalysts.
Development of elastic liposomes of caffeine for the treatment of cellulite
Authors:   , Kao-ian Chungrida 
Published: November 2023

In this study, caffeine elastic liposomes were developed for cellulite treatment by using the combination of surfactant and ethanol. The elastic liposomes studied consisted of phosphatidylcholine as the structural lipid, Span® 80 or Tween® 80 of the same molar ratio (5-10% w/w and 15-25% w/w of total lipid, respectively) as the edge activator and various concentrations of ethanol (5-25% v/v). The effects of type and amount of surfactants and concentration of ethanol on physical properties i.e., vesicle formation, size and size distribution and elasticity of blank liposomes were investigated. The blank liposome formulations with highest elasticity of each surfactant were selected to prepare the caffeine-containing elastic liposomes. These elastic liposomes were characterized for physical properties including entrapment efficiency and physical stability. The skin delivery of caffeine from the chosen elastic liposome formulations were carried out in vitro with modified Franz diffusion cells under the non-occlusive condition using newborn pig skin as the model membrane. The results showed that the complete vesicle formation was observed at low ethanol concentrations (5-15% v/v). The vesicle size of liposomes composed of Span® 80 and Tween® 80 was in the range of 5.84-8.08 µm and 3.73-5.27 µm, respectively. The combination of surfactant and ethanol showed significant effects on physical properties of elastic liposomes. The elasticity of liposomes containing Span® 80 and Tween® 80 was in the range of 27.07-79.86% and 8.44-15.74%, respectively. The formulations with highest elasticity, S7.5_5 with Span® 80 7.5% w/w and ethanol 5% v/v and T20_5 with Tween® 80 20% w/w and ethanol 5% v/v, were chosen to load caffeine. In general, physical properties of caffeine elastic liposomes were similar to the corresponding blank liposomes. However, caffeine loading decreased the elasticity of caffeine-entrapped elastic liposome formulations by approximately 20-30% compared to that of the blank elastic liposomes. The elasticity values of the caffeine-loaded elastic liposome formulations S7.5_5 and T20_5 were 53.46±8.63% and 11.93±0.46%, respectively. The entrapment efficiency values of S7.5_5 was lower than that of T20_5 (35.05±0.60 and 41.31±3.32% w/w, respectively). Skin permeation from S7.5_5 and T20_5 were significantly higher than that from the hydro-alcoholic solution used as the aqueous phase of these elastic liposomes. However, despite the profound difference in elasticity between the 2 formulations, no significantly differences were seen in most permeation parameters studied. The only significant difference detected was the enhancement factor of caffeine amount in the skin, the mean of which was almost doubled for the S7.5_5 formulation when compared to the T20_5 formulation.
Formulation development of celecoxib-cyclodextrin suspensions for ophthalmic delivery
Authors:   , Kulsirachote Pakin 
Published: November 2023

Celecoxib (CCB), a nonsteroidal anti-inflammatory drug (NSAID), could be beneficial in the treatment of age-related macular degeneration (AMD) and diabetic retinopathy (DR) through the inhibition of COX-2 enzyme. Currently, the several methods can deliver drugs to the back of the eye. i.e., oral, intravitreal injection, subconjunctival injection and topical. Among routes of administration, topical eye drop is non-invasive method and local effects. However, due to low aqueous solubility of CCB, it hampers ocular bioavailability. Thus, the aim of this study was to develop topical eye drop suspensions containing cyclodextrin (CD) and polymer delivering to the posterior segment of the eye. CDs, the solubilizer, i.e., alpha-CD, beta-CD, gamma-CD, HP-beta-CD and RM-beta-CD and mucoadhesive polymers i.e., hydroxypropylmethylcellulose (HPMC) chitosan and hyaluronic acid (HA) were used. The phase solubility profiles and CCB/CD complex characteristics were investigated. RM-beta-CD exhibited the greatest solubilizer among CDs tested. HPMC was the potential polymer to form ternary complex with CCB/RM-beta-CD which gave 11-folds complexation efficiency higher than that of its binary complex. The aggregate size of ternary complexes in solution were found in the range of 250 - 350 nm which could solubilize themselves resulting in increasing CCB solubility. The data obtained from FT-IR, DSC, PXRD and 1H-NMR indicated that there were interaction of CCB with CD as inclusion complex. The CCB eye drops formulations were prepared by unheated and heating method (sonication at the temperature of 70oC for 1 hour). The physicochemical and chemical characterizations, mucoadhesive properties and in-vitro permeation were determined. The physicochemical properties i.e., appearance, pH, osmolality and viscosity were in acceptable range. The particle sizes below 10 µm indicated possibly no irritation to the eye. The formulation containing HA showed the excellent mucoadhesive properties. The increasing of % CCB content in most cases by heat resulting in higher flux permeation through semipermeable membrane and through simulated artificial vitreous humor, especially the formulation containing RM-beta-CD and HA (0.5% w/v). Therefore, it may be a promising candidate as topical formulation which can deliver CCB to the posterior segment of eye to treat AMD and DR.

This program would be another modality to apply in obesity for enhancing cardiorespiratory fitness and QOL, and reduction in body composition. Trial registration: TCTR20160818003.
Determination of occupational risk and exposure to pesticide residues on vegetables among greengrocers in fresh market Bangkok Thailand
Authors:   , Ong-artborirak Parichat 
Published: November 2023

This mixed methods study aimed at assessing the magnitude of health risk from occupational exposure to pesticide residues (PRs) on vegetables. The study was conducted among 91 greengrocers in Padung Krung Kasem market, Bangkok. Data was collected in dry (April-May) and wet (August-October) seasons, including face-to-face interview, hand wipe sampling, and blood cholinesterase (ChE) level test, and then in-depth interview was conducted. The study revealed that all hand wipe samples contained many kinds of insecticides, including organophosphates, carbamates, and pyrethroids. PRs on hands detected in all samples were chlorpyrifos and cypermethrin. Wilcoxon signed rank test revealed that amount of chlorpyrifos and types of PRs on hands in the wet season significantly decreased when compared to the dry season (p<0.05), while amount of cypermethrin did not significantly differ. In addition, there were statistically significant differences in blood ChE level in both seasons (p<0.001). The most reported symptoms from exposure to PRs were fatigue/tiredness, skin rash/itching, headache, and eye irritation/blurred vision. At 99th percentile values of PR exposure, average daily dose (ADD) was 2.42x10-5 mg/kg/day and hazard index did not exceed acceptable level (HI=0.287). Besides, the significant relationship among practice regarding PR exposure, PRs on hands, ChE level, and health symptoms were found (p<0.05). Occupational exposure to PRs with poor practice may pose health effects. These findings suggest that risk communication among greengrocers should be done with guideline related to pesticide contamination in vegetables, especially proper personal hygiene practice, to prevent them from PR exposure and potential health risks.

Introduction: Mammography is a diagnostic tool that is routinely used to test women for breast cancer. While it has been shown to be beneficial in detecting early-stage malignancies, it can also have emotional and psychological consequences for patients. The goal of this study is to dive into the emotional and psychological experiences of mammography patients. We hope to obtain a better understanding of the potential complications and problems faced by women during the screening process by investigating these elements.
Materials and Methods: The Psychological Consequences Questionnaire (PCQ) and a self-administered questionnaire were used to collect data. SPSS was used for statistical analysis. All participants were given information about mammography technology and safety, and their participation was based on informed consent.
Results: The study included 60 women ranging in age from 40 to 67 years old, with a mean age of 50.22. The PCQ results revealed a high prevalence of symptoms such as difficulty sleeping, changes in appetite, depression or unhappy feelings, fear and panic, nervousness or tension, feeling under pressure, withholding items, venting frustrations on others, withdrawal from relationships, difficulty with daily tasks, and difficulties fulfilling obligations. These findings shed light on the psychological repercussions that people face and point to the necessity for support networks or therapy to address these concerns.
Conclusion: This research focuses on the emotional and psychological effects of mammography on women. The data suggest that anxiety is a common feeling for women undergoing mammography, which could be exacerbated by previous negative experiences or fear of breast cancer. In order to provide holistic and comprehensive care, healthcare providers must recognize and meet patients' emotional and psychological needs.

Published: November 2023

We study the complete integrability of a system describing the motion of a rigid body with a fixed point and a particle oscillating in it in the absence of external forces. Using the Ziglin-Morales-Ramis theory, we prove rigorously that the considered system is integrable only in the case of dynamical symmetry.

AN ANALYSIS OF HOW THE PRICING INSTRUMENT POLICIES AFFECT THE PERFORMANCE OF TRANSPORT SERVICES IN NAIROBI METROPOLITAN
Authors: GATHUNGU CYNTHIA MUGURE , NJOROGE JANE 
Published: November 2023

Transport services contribution to the Kenyan economy is widely acknowledged, they cut across all sectors of the economy and provide many employment opportunities and generate widespread economic benefits. Considering the immense contribution of transport in economic growth, a reduction in transport cost is expected to spur economic growth and create a favorable business environment for Small and Medium enterprises. This study investigated how the Pricing instrument policies affect the performance of transport services in Nairobi Metropolitan. 384 participants ware sampled and 260 responded amounting to 67.7 percent response rate. Descriptive correlational study design was applied. Multiple regression model showed that there was a significant relationship between performance of the transport services sector and the policies implemented by the city management where multiple determinations coefficient of 0.056 displayed that infrastructure investment policies, price instrument policies and license procedures policies independent variables lead to 56 percent in performance of transport services in Nairobi Metropolitan Services. These findings support the fact that policy development and implementation in the transport sector affect the business organizations operating in the sector. Therefore, policy formulation or development, changes to the transport sector can only be realized when the policies are implemented appropriately. Therefore, this study recommended and encouraged effective policy implementation in the NMS and ensure that transportation services policies are implemented appropriately to make huge difference in the transport business sector. However, more research is needed using different methodological approaches to quantify the impacts of policies in the sector on growth and development. Other studies can examine how these policies affected other organizational outcomes, such as customer satisfaction and stakeholder wealth maximization to improve the quality of services offered in the transport sector.
