Published: April 2023

The purpose of the study was to determine the roughness coefficient of the main channel bed BP-1 of the Sarpinskaya watering-irrigation system (SWIS) and to compare the data obtained with the normative values. The materials for performing the calculations were: an explanatory note to the project of the second stage of the construction of the SWIS, passports of the main and inter-farm channels of the system (2015), a technical report of the operating organization for 2021, data of full-scale measurements of the depths and velocities of the water flow in the considered alignment using the «speed-area» method, the results of full-scale surveys of the water supply network and HTS SWIS, as well as data from GIS maps and literary sources. The methodology for calculating the elements of the live section of the channels took into account the recommendations of SP 100.13330.2016. The calculation of the roughness coefficients of the channels was carried out using known dependencies, including the Chezy formula, the Manning equation, the dependencies of I.I. Agroskin and N.N. Pavlovsky. The elements of the living section are determined and the values of the roughness coeffi cient in the considered alignment of the main channel are obtained. At the same time, the calculated values of the roughness coefficient obtained have good convergence (the deviation of the results does not exceed –2.8%). However, the obtained values exceed the normative value of the roughness coefficient by 1.6-1.64 times, which is explained not only by the overgrowth of the channel bed with aquatic vegetation, but also by the peculiarity of the shape of the cross-section of this channel, which in the area under consideration has a signifi cant width along the bottom. The calculated values of the roughness coeffi cient obtained indicate the overgrowth of the main canal bed, which was confi rmed during field surveys of the water supply network of this canal in the spring of 2022. In view of this, it is necessary to carry out preventive measures in a timely manner aimed at reducing the additional hydraulic resistance caused by overgrowth of the riverbed with vegetation.

Published: April 2023

In this study, we applied an exploratory approach to develop a tea culture education curriculum on the Metaverse, which has been receiving considerable attention as a new educational platform beyond the existing online setting. Our findings provide a direction to the development of a creative education curriculum using Metaverse content that can conserve the traditional aspects of Korean tea culture, while creating new value and types of knowledge. By analyzing the traits of different Metaverse platforms, Zepeto was selected as it provides a number of maps that include Korean characteristics and culture, as well as three-dimensional characters and multiple languages; it also allows users to create their own maps. However, due to limitations on sharing content and objects, a map using only images was produced. Based on this, a tea culture education teaching-learning curriculum using the Metaverse was proposed. The significance of this study is that it suggests a new approach in the field of tea culture education that can be more fun and interesting for students. In addition, directions have been proposed for a new type of tea culture education and character education program in the form of etiquette education on the Metaverse beyond existing etiquette education.

Yunnan Pu’er Tea is made from old tea trees and has recently become popular in Korea, commanding a high price. However, its ingredients and effects are not properly known. This study aimed to evaluate the possibility of Gimhae primary tea made by the method of Yunnan Pu'er tea as a subsititute for Yunnan Pu'er tea by analyzing its ingredients of caffeine, catechin, free amino acid, gallic acid, and polyphenol, evaluating its antioxidant activity and conducting a taste analysis. In most component analyses, Yunnan primary tea showed a slightly higher component content on average, but there were no significant differences compared to Gimhae primary tea. However, Gimhae primary tea had on average 5% higher total amino acids and it scored higher overall in the value of four taste sensors, excluding sour taste in a taste analysis using electronic tongues. This suggests that Gimhae primary tea has the potential to be a multi-flavored tea. Daesung-dong (T8), a Gimhae wild tea, which showed results similar to Yunnan tea in all its ingredients, is thus considered as a suitable alternative to Yunnan tea by making it appropriate for use as a fermented tea. for use as a fermented tea.

Published: April 2023

A survey was conducted in the agricultural farms in Dhulikhel Municipality, mid-hill, Kavre, Nepal aiming at assessing the status of agrobiodiversity with the purpose of understanding its role in food security taking altogether 133 farming households scattered in several settlements with lowland, upland, and home garden being the general agricultural land use systems. Biodiversity index: Shannon-Wiener Index was used to assess diversity of plant. The main purpose was to assess the farm agrobiodiversity and to find out whether biodiversity level has a direct link to household food self-sufficiency. For descriptive analysis frequency, percentage, mean and standard errors were used. In the case of inferential statistics independent sample t - test and binary logistic was used to find the odd ratio of practicing home garden. The result showed that the average landholding size was 0.66 ha/household with 0.37 ha, 0.3 ha, and 0.06 ha being upland, low land, and home garden, respectively. A total of 136 plant species were documented out of which 74 were the effective number of species in the study area. Among the used plants, fodder shared 27% of the total plant diversity followed by fruit (21%), vegetable (19%), medicinal plants (8%), pulses (8%), spices (7%), oilseeds (5%) and cereals (5%). Similarly, the mean livestock unit (LSU) was 2.65. The overall Shannon-Wiener Index was 4.30 indicating high diversity of species and 87.7% of the species were evenly distributed. The Index was higher for vegetable (3.11) followed by fruits (2.9) and fodder (2.85). Higher diversity was found in fodder trees in lowlands whereas vegetable species were more diverse in upland and home garden. Similarly, the Index was 4.29 in the upland whereas it was 4.078 in the home garden followed by 3.13 in the lowland. The evenness was 0.899, 0.87, and 0.74 in upland, home garden and lowland, respectively. Higher species diversity revealed that the site was rich in agrobiodiversity. A significant positive correlation (0.22) was observed between Shannon-Wiener Index and farming years. Similarly, positive correlation (0.33) was found between an increase in the level of agrobiodiversity and food self-sufficiency. The result demonstrated that increasing crop diversity increases the household’s ability towards food sufficiency implying the need for the formulation and implementation of efficient policy to conserve the agrobiodiversity at municipality as well as national levels.

A tomografia por emissão de pósitrons (PET) e a ressonância magnética (MR) são modalidades relevantes no estudo do envelhecimento cerebral. A deposição de placa beta-amiloide (bA) pode ser avaliada por PET utilizando radiotraçadores específicos, como [11C]PiB ou [18F]Florbetaben. A escala Centiloide (CL) foi desenvolvida para reduzir a variabilidade do protocolo de processamento e produzir uma quantificação harmonizada das imagens PET de bA. O objetivo deste estudo é apresentar o processo de implementação da escala CL para o radiotraçador [18F]Florbetaben em nossa instituição. Para tanto, é preciso validar o pipeline de processamento e análise das imagens com os dados disponibilizados pela Rede Interativa da Associação Global de Alzheimer (GAAIN) para o radiotraçador [18F]Florbetaben e [11C]PiB. O GAAIN possui imagens de PET e MR de 10 controles (bA negativos) e 25 indivíduos bA positivos, incluindo idosos cognitivamente saudáveis, com comprometimento cognitivo leve, doença de Alzheimer e demência frontotemporal. Na escala CL são utilizados os valores de captação entre região cortical global (CTX), que considera as regiões córtex frontal, temporal, parietal, precuneus, estriato anterior e córtex insular, e o cerebelo inteiro (WC), como região de referência. O processamento das imagens foi realizado utilizando o software PMOD, com a ferramenta PNEURO. Como resultado, obtivemos uma forte correlação entre os valores de [18F]Florbetaben e [11C]PiB para os mesmos indivíduos. A equação final que transforma os valores SUVR do [18F]Florbetaben para escala CL em nossa instituição é: CLFBB= 156,47 * SUVR*PIBind - 157,47. A equação foi validada e atingiu os valores mínimos requeridos pelo Klunk et al (2015) de coeficiente de determinação R²=0,997, coeficiente angular igual a 1,00 e coeficiente linear igual a 1,34.Conclui-se que a implementação da escala CL em nossa instituição é viável,constituindo um passo importante para a utilização clínica dessa escala para investigação longitudinal de indivíduos em processo de envelhecimento usando radiotraçadores bA.

Published: April 2023

Some of the limitations of a cost-effective alkaline surfactant flooding method include chemical precipitation and other formation damage issue which has greatly affected the application of chemical flooding especially in high salinity reservoirs. This study ascertains the chelating attributes of Ethylene-diamine-tetracetic Acid-(EDTA/NaOH), investigates the ability of EDTA/NaOH and an anionic surfactant to improve oil recovery in heavy oil sandstone formation. Petrophysical analysis of the crude oil and core samples were performed. Hard brine at 5.1% optimal salinity and 0.2 wt.% surfactant imbibition were performed on the sandstone core plug for over 240 hrs. and the volume of oil recovered was determined using Amott imbibition cells. Sandstone core flooding test was thereafter conducted using the alkaline -surfactant solution at optimal salinity. Spontaneous imbibition results showed that surfactant imbibition (26.6%) produced a higher recovery than hard brine recovery (18.7%) after 240hrs. Sandstone core flooding results showed increased heavy oil recovery of 37% OOIP with alkaline-surfactant solution and additional 8% recovery was achieved by performing a final chase brine flooding, totaling 45% indicating that traces of alkaline-surfactant, in the core, aided the final imbibition process. This study underpins and complements several research solutions concerned with flooding in harsh oilfield terrains, thus making the overall process cost-effective and less time- consuming.

This paper presents an experimental study of concrete beams with cold-formedsteeladded as shear reinforcement. Cold-formed steel (CFS), also called light gauge steel or metal studs, is cold-formed into “C” or “Z” shaped members, capable of holding heavy loads. “Cold-Formed” means the sections are shaped at room temperature by guiding the steel through a series of rollers. Previous researchers have shown that CFSgenerally has a yield stress of 350 MPa to 550 MPa, but its use is mostly focused on anticipating beam bending. The purpose ofthis study was to determine the behavior of concrete beams with CFS added as a stirrup to increase the shear capacity of the beam. Two beams have been made with a size of 150x250x860 mm using the same 6D10 flexural reinforcement. One as a control beam (SB-C) using steel bar stirrups ∅5-200mm, the other as a beam added to CFS as stirrup reinforcement (SB-CFS) with a CFS cross section 20 mm wide, 0.75 thick mm and 120 mm CFS stirrup spacing. The test is carried out by applying a one-point loadingin the middle of the span of the beam so that the a/d ratio is 1.36. The parameters to be recorded are the capacity of the beam, the deflection that occurs, and the stiffness of the beam. The test data have been compared with the theoretical analysis results using the numerical software Response-2000. The resultshave shown that the increase in the shear capacity of the beam with the addition of CFS is 12.7% even though,according to Response-2000 analysis,it is 38.7%. The failure that occurs is shear failure according to the predetermined a/d ratio.

The Recycled Waste Glass (RWG) is a most suitable substitute to the natural sand to be utilized in the concrete manufacturing industryand Rice Husk Ash (RHA) is an agricultural by-product having enormous characteristicsto utilize as cementitious material in concrete. This study was carried out to understand the effects of RHA as partial replacement to cement and RWG as a partial replacement to natural fine aggregate with 10%, 20% and 30% levels of substitutions in the concrete mixes respectively. The effects were investigated on the workability and compressive strength characteristics of fresh and hardened concrete. A total of 4 mixtures were prepared for M15 grade concrete with 1:2:4 concrete proportions and water to cement ratio of 0.55. Out of them one was controlled mixture and three were with 10%, 20% and 30% equal substitution levels of combined RHA and RWG. The acquired results showed that the slump values were like that of conventional concrete at combined incorporation of RHA and RWG at 10% replacement, but a decline was noticed at 20% and 30% replacement. The decline was due to the more surface area of RHA which absorbs more water. The compressive strength at 10%RHA and 10% RWG combined replacement in concrete mix was increased by 9.7% as compared to controlled mix after 28 days curing. The results were similar at 20%RHA and 20%RWG incorporation as compared to controlled concrete mix. It is concluded that RHA and RGW can be utilized at 10% equal replacement in the concrete and the cost of construction can be reduced. This research work will be helpful in developing a comprehensive scientific data base on combined utilization of RHA and RWG in the concrete mixes and the upcoming scientists, scholars and students will be benefitted.

Due to the high demand in the fisheries market, species identification is vital for commercial fish to avoid mislabeling and fraud in marketplaces. The increasingly threatening human activities like overfishing, blast fishing, poison fishing, and trawling have become the major threats to fish and caused an urgent need for documentation of both marine and freshwater fishes. Commercial fish products sometimes are sold by their parts, such as fins which further create confusion for identification purposes.Morphological identification also requires highly skilled ichthyologists to avoid misidentification. Thus, identification through DNA barcoding can be utilized as it holds the potential for accurate and rapid identification. Here we identified the commercial marine fish species sold in Muar Fish Market, Johor, using the Cytochrome Oxidase subunit I (COI) gene of mitochondrial DNA (mtDNA). A 700 base-pair sequence of the COI region was targeted by amplifying extracted DNA from 28 fin samples collected from the fish market. From 28 samples, we successfully sequenced 16 samples, and by using phylogenetic analysis, (Neighbor-Joining (NJ), Maximum Parsimony (MP) and Bayesian Inference (BI)) we successfully identified the samples belonging to nine families (Scombridae, Platycephalidae, Carangidae, Ariidae, Polynemidae, Coryphaenidae, Sphyraenidae, Muraenesocidae, Engraiulidae), 12 genera and 16 species. This study reports the first documentation of commercial fish sold in Muar through the DNA barcoding technique. This technique should be expanded further to identify any species with important conservation implications, such as endangered species, for improved management of fisheries in Malaysia

A methodological approach to the formation and description of data on the design and technological features of parts under technological preparation of machining industries is presented, the difference, if compared to other well-known approaches, lies in recording of additional data that is not explicitly reflected in the reference design. As an additional information component, it is proposed to use: information on the mutual influence of one elementary surface on another or others, i.e. dimensioning specifications of other surfaces; data on the dimensional features of each elementary surface, which is not shown in the drawings; extreme geometric shape deviations for elementary surfaces and also mutual arrangement between elementary surfaces; data on the design bases of the part in question. The formation of a database of machined parts is given graphically, which makes it possible to use a wide range of mathematical tools technique in the creation of formalized models, providing their uncomplicated adaptation for using in existing computer-aided design systems. The analysis of additional design and technological parameters allows assessing the interdependence of the dimensions and characteristics of each of the part surfaces and the parameters of other surfaces, ensuring the quality of decision-making at the stages of technological preparation based on increasing the degree of reliability of information flows. The obtained results expand the possibilities of conducting dimensional analysis of the basic, operational and interoperation connections of the developed technical processes, increasing the level of automation in design procedures. Produced graphical models, aimed at reducing the complexity of design actions outline, are able to expand, due to the approximation to the traditional data specification of technological equipment, the possibility of taking into account the state of production capacities in machining production on a real time scale. They also contribute to the deciding modern issues on effective engineering complexes formation.

This mixed-method study examines Michigan’s Partnership policy for school turnaround, which positions the district and superintendents as key policy implementation actors. We first interviewed 21 of 35 Partnership superintendents/leaders across Michigan and surveyed teachers to understand the initial response to the turnaround policy and the strategic planning process. We then used our understanding of these leaders’ responses to conduct a purposively sampled embedded multiple comparative case study of three varied districts. These case studies helped us more deeply understand and compare how districts engaged in the process of crafting coherence and school-level stakeholders’ perceptions of activities related to coherence and implementation of the reform. Based on these two levels of data collection and analysis, we found that many leaders used the opportunity to create new changes, roles, and partnerships, but the majority also symbolically adopted policy demands by aligning their turnaround plans with pre-existing efforts. Using cross-case comparisons of our three districts, we argue that some degree of strategic buffering from policy demands may be warranted, especially when districts have low capacity and face significant challenges recruiting and retaining teachers.
Ultrasound-Assisted Oxidative Desulfurization of Diesel

Due to the dramatic environmental impact of sulfur emissions associated with the exhaust of diesel engines, last environmental regulations for ultra-low-sulfur diesel require a very deep desulfurization (up to 15 ppm), which cannot be met by the conventional hydrodesulfurization units alone. The proposed method involves a batch ultrasound-assisted oxidative desulfurization (UAODS) of a previously hydrotreated diesel (containing 480 ppm sulfur) so as to convert the residual sulfur-bearing compounds into their corresponding highly polar oxides, which can be eliminated easily by extraction with a certain highly polar solvent. The oxidizing system utilized was H2O2 as an oxidant, CH3COOH as a promoter, with FeSO4 as a catalyst; whereas acetonitrile was used as extractant. The major influential parameters related to UAODS process have been investigated, namely: ratio of oxidant/fuel, ratio of the promoter/oxidant, dose of catalyst, reaction temperature, and intensity of ultrasonic waves. Kinetics of the reaction has been also studied; it was observed that the UAODS of diesel fuels fitted pseudo-first-order kinetics under the best experimental conditions, whereas values of the apparent rate constant and activation energy were 0.373 min-1 and 24 KJ/mol, respectively. The oxidation treatment, in combination with ultrasonic irradiation, revealed a synergistic effect for diesel desulfurization. The experimental results showed that sulfur removal efficiency could amount to 98% at mild operating conditions (70 ○C and 1 bar). This indicates that the process is efficient and promising for the production of ultra-low-sulfur diesel fuels.

The effects of the permeation cement grout with fly ash on the sandy soil skeleton were studied in the present work in two phase; first phase the shear strength parameters, and the second phase effect of these grouted materials on volume grouted zone by injection (51) cm³ of slurry in sandy soil placed in steel cylinder model with dimension 15 cm in diameter and 30 cm in height. The soil sample was obtained from Karbala city and it is classified as poorly graded sand (SP) according to USCS. The soil samples were improved by cement grout with three percentages weight of water cement ratio (w:c); (0.1w:0.9c, 0.8w:0.2c, and 0.7w:0.3c), while the soil samples were dehydrated for one day curing time. Fly ash class (F) was used with cement grout as filler material; it was added to the mixture as a replacement material for cement in weight percentages; 10%, 25% and 40%. According to the results of tests, both shear strength and approximate volume of the effective grouted zone for treated samples soil with cement grout was increased when the water cement ratio decreased. Fly ash with cement grout needs to increase the water demand for the grout mixing to give best results in both shear strength and filling the soil voids.

Como implantar o ciclo completo de polícia no Brasil?
Authors: Sapori Luis Flávio
Published: April 2023

O artigo “Como implantar o ciclo completo de polícia no Brasil?”, de Luis Flávio Sapori, encerra este suplemento analisando como é possível viabilizar um ciclo completo de ação policial. Observando diferentes países, Sapori chama atenção para a diversidade de arranjos institucionais de sistemas policiais existentes e para o fato de que não há um modelo ideal a ser seguido. E, a partir da realidade institucional brasileira, analisa três possibilidades de implantação do “ciclo completo de ação policial”: 1) através da unificação das polícias civil e militar em cada unidade da federação; 2) através da atribuição das funções de polícia ostensiva e judiciárias para ambas polícias; e 3) através da atribuição das funções de polícia ostensiva e judiciárias para ambas polícias, mas com a divisão do ciclo completo por competência penal.

Published: April 2023

Neste artigo são analisadas violências que acometem a juventude na cidade de São Paulo, utilizando dados quantitativos produzidos pelas Secretarias Municipais de Saúde, Serviços e Assistência e Desenvolvimento Social. Os dados mostram: a) a significativa tendência de diminuição no número de homicídios na cidade de São Paulo na última década, embora a mesma tendência não seja observada nas mortes decorrentes da ação policial; b) que na aferição do uso da força policial verifica-se desproporcionalidade na ação das polícias na capital paulista; c) o perfil específico das vítimas da letalidade policial e a distribuição espacial dessas mortes na cidade de São Paulo. Focalizam-se os desafios e limites encontrados pelos municípios na proposição de programas de avaliação e redução da violência diante de velhos dilemas da segurança pública, como é o caso da letalidade policial. Conclui-se que a violência policial é um dos principais desafios para a vida segura dos jovens paulistanos.
