Authors: Nazaruk M. M. , Halianta L. A.
Published: April 2023

Purpose. Based on the analysis of socio-ecological conditions for the development of innovative nature management in the communities in Lviv region, to determine the main factors of innovative industrial production.

Methods. Analysis, synthesis, comparison.

Results. The concept of "industrial nature management in the community" is covered. We described the socio-ecological conditions for the development of innovative nature management and the main factors of innovative industrial nature management in modern decentralization within the newly created territorial communities are as follows: technology, legislation in the field of innovation, demand for innovative products, information and investment resources, highly skilled labor, efficiency of management.. Innovative activity within the enterprises of Lviv region and the state of the technological structure of industrial production in the region are characterized. Attention is paid to the possibility of structural restructuring of industrial nature management.The peculiarities of the development of innovative nature management within the Lviv region, the mechanisms of stimulating investment and innovative development of territorial communities are highlighted. The concept of "industrial park" is considered, as well as the concept of creating industrial parks. The functional purpose of nine industrial parks, which are planned to be created within the territory of Lviv region, is described. The industrial zoning of the region is highlighted and the main industrial centers within them are characterized.

Conclusions. Structural restructuring of industrial nature management should be based on optimizing the use of existing in the community natural resource, socio-economic, cultural and historical potentials, optimizing the directions and scale of nature management. At the same time, the least environmentally harmful industries deserve the priority development.
Comparative characteristics of the land use structure for different types of territorial communities
Authors: Chebolda I. Y. , Kuzyk I. R.
Published: April 2023

Purpose. The assess and compare the structure of land use of urban, township and rural territorial communities, to develop an optimization model to land use in case of decentralization

Methods. Assessment, comparative-geographical, geoinformation, statistical, mathematical, geoecological analysis and optimization modeling. During the study, special methods were used to determine the anthropogenic pressure, coefficients of ecological stability and anthropogenic transformation of different types territorial communities.

Results. According to the results of comparative assessment of the land use structure of urban, township and rural territorial communities, it was found that all three types of communities are characterized by a high degree of plowing (˃60%) and low forest share (5-10%). The share of natural lands within the studied territorial communities is 23-30%. The calculated coefficients of anthropogenic transformation, ecological stability, anthropogenic load, showed that Vyshnivets township and Borsukivska rural territorial communities belong to the category of ecologically unstable territories, Lanovets urban territorial community - to medium ecologically stable territories. In all three types of territorial communities, landscapes are moderately transformed. Urban, township and rural territorial communities experience a sufficiently high (above average) anthropogenic pressure. The obtained results of calculations create objective preconditions for optimizing the structure of land use of the studied territorial communities.

Conclusions. To correct and improve the situation, to bring the territories of the studied territorial communities of different types to ecological stability, it is necessary to implement a number of optimization measures. The developed optimization model of land use of Lanovets city, Vyshnivets township and Borsukivka rural territorial communities envisages reduction of arable lands by 20-26%, increase of forest cover by 13-18% and bringing the share of natural lands to the optimal 50%. The implementation of such an approach requires a change in the purpose of individual land plots and the organization of their landscape-adapted use.
Assessment of general and professional competences formation level by bachelors studying of specialty 101 Ecology
Authors: Maksymenko N. V.
Published: April 2023

Purpose. To identify the gaps and weak points of the Education-and-professional programme for the Specialty 101 Ecology based on students' self-assessment of the formation of competencies to improve the training of bachelor's degree specialists.

Methods. The study is based on a statistically reliable survey among students. Analytical-synthetic method, graphic and logical generalization methods are used.

Results. The study compared the level of competencies in students after the third and the forth years of study. The categories "excellent", "good", "satisfactory" and "not mastered" were used for evaluation. It is established that the general competencies of graduates, in contrast to the third-year students are considered to be "good" and "excellent", which was influenced by industrial practice. There are three groups of professional competencies by level of change and general formation. The first group is a block of theoretical competencies that are formed during first three years of study and the level of knowledge in both groups of respondents is almost the same. The second group-competencies are rated by graduated lower than by the third-year students. The reason is the internship, during which students realized the low level of preparation for the practical work. The third one is the competencies that raised self-esteem after the internship. Ways to solve each problem situation are suggested.

Conclusions. The formation of general competencies in students of both years fo study is good, except for competencies related to learning a foreign language, which can be changed by increasing motivation to learn languages. Different formation of professional competencies encourages changes in the Education-and-professional programme and the addition of work programs with topics that focus on future professional work, as well as stimulating extracurricular activities.
Biotic homogenization of dendroflora in the conditions of the megapolis (Dnipro, Ukraine)
Authors: Shamray M. V. , Didur O. O.
Published: April 2023

Purpose. Biodiversity assessment and clarification of the trend towards homogenization of the dendroflora of the Shevchenko Park (Dnipro, Ukraine).

Methods. Floristic methods of research are applied - elucidation of the taxonomic composition and selection of the adventitious fraction of dendroflora, methods of species richness assessment (according to the Menkhinik index and Margalef index), determination of floristic commonality (according to the Jaccard index) and floristic homogeneity (according to the Koch index of biotic dispersion), methods of ecological analysis (by biomorphs and ecomorphs), physical, physicochemical, chemical methods of soil analysis, soil biological activity, statistical methods of data processing (descriptive statistics and correlation analysis).

Results. It was established that artificial stands of trees in the Shevchenko Park are capable of forming a sufficient amount of viable undergrowth of autochthonous and introduced (adventurous) species, the ratio of which is 37.0% to 63.0%. The amount of tree growth of adventive sites in the areas according to the level of recreational load is distributed as follows: with no load - 38.5% of the number of self-regenerating trees, with moderate - 68.2%, with strong - 80.5%. The indexes of species richness of Margalef and Menkhinik of self-regenerating tree species for the site with a strong recreational load turned out to be the largest (due to adventitious species) compared to the sites with no and moderate recreational load. Koch index of biotic dispersion is 50.0%. Correlation coefficients between the number of allochthonous and autochthonous tree species that have self-regenerated for the studied areas with strong, moderate and no recreational load are statistically significant (0.73, 0.76, 0.77 respectively).

Conclusions. On the territory of the investigated areas of the park, there are 14 tree species capable of seed self-regeneration, which taxonomically belong to 12 genera and 10 families. Of them, 9 adventive species were registered, represented by 9 genera and 7 families with the leading family Sapindaceae. The calculated index of biotic dispersion testifies to the presence of a process of floristic homogenization of the forest stand on the territory of the park. As part of the adventitious fraction of the self-regenerating dendroflora, there is an increased invasion of Ailanthus altissima and the occurrence of such neophyte species as Celtis occidentalis and Acer negundo, which indicates the penetration of alien species into the local flora and a potential threat to natural floristic diversity.
“It's Always Good to have a Beer with your Teammates”: Alcohol Consumption and Hegemonic Masculinity within Community Sports Clubs in Aotearoa New Zealand
Authors:   , Lutherus Keegan
Published: April 2023

Traditionally, males have been dominant in community sports and have consumed alcohol at higher rates when compared to other genders in Aotearoa. A theory, developed by Connell, known as hegemonic masculinity has been linked to alcohol consumption practices as well as being involved in sports, including competitive sports. Hegemonic masculinity is a social and cultural construct that upholds a status hierarchy, favouring those who follow the dominant consensus around gender, by promoting masculinities and oppressing femininities. Western ideals have led to a version of hegemonic masculinity that values attributes and behaviours such as being unconcerned with health and prioritising being strong over seeking help. This research aimed to explore how hegemonic masculinity and alcohol consumption function within New Zealand community sports clubs. In this study, 12 participants (10 males, 2 females, aged 23-56), who belonged to sports clubs within the Greater Wellington Region, undertook semi-structured individual interviews with the researcher. Following transcription, the data were analysed thematically. The analysis identified three main themes, namely pervasiveness: alcohol is everywhere in the club space, masculine behaviours dominate the club space, and feeling alienated within the club. Each main theme, and their 10 subthemes, were interrelated and highlighted how the pervasive nature of alcohol within the club was upheld by the dominance of masculinity, which ultimately led to feelings of alienation for some members. Findings reinforce that hegemonic masculinity and alcohol consumption remain pervasive within male-dominated community sports settings, which subordinates those who do not conform to the status quo. This is preserved by current formal hierarchies that favour dominant groups within this space. Furthermore, conforming to dominant practices has become a mechanism for belonging and determines what behaviours are deemed appropriate. Harmful behaviours that were related to hegemonic masculinity were exacerbated by alcohol consumption. Policymakers and future researchers must seek ways to change the current power dynamics and drinking practices, which are perpetuated by hegemonic masculine norms, to promote a more inclusive and safer space for all members.
The ontogenesis of human capital in an enterprise
Authors: Zhdanov D. A.
Published: April 2023

The management of the company traditionally faces the task of increasing the effectiveness of human capital (HC), its timely transformation, and the early accumulation of the necessary human resources. In this regard, the purpose of this work was to establish a rational set of transformations that HC goes through from its inception to the end of its existence. The human capital of an enterprise in the work is understood as a combination of the corporate human capital of the organization and the individual human capital of its employees. The methodological basis of the study was the four-component system economic theory, the evolutionary theory of the firm, in particular, the features of the life cycles of organizations (LCO) and, finally, the theory of human capital. The involvement of these scientific approaches made it possible to demonstrate that the evolution of human capital in the correct version (during the transition from one stage of the life cycle to another) occurs synchronously with the change in the management tasks of the enterprise that arise at each stage of the life cycle of the organization. They determine the priority requests to the elements of the human capital, leading to the rotation of the latter and the selection of the most demanded among them for the corresponding stage of the life cycle. From a scientific point of view, the main result of the work was the identification of unified key stages that make up a consistent cycle of development of the human capital of an enterprise (determining its evolution), as well as the establishment of the positions of corporate and individual human capital, the most focused on solving the problems of the corresponding stage. Verification of the results obtained was carried out on the example of the evolution of the basic elements of the enterprise’s human capital — corporate culture and management style. The conclusions drawn are intended to help the management of companies to determine the components of human capital, which are mainly in demand at the corresponding stages of the life of the organization, and to choose in a timely manner the ways to increase the potential and efficiency of personnel.

The purpose of article is to study the issues of state regulation of the oil and gas complex, including current areas of its improvement, environmental factors, in the context of the digitalization of the global economic system and the global energy market. The author investigated the importance of increasing the efficiency of state regulation of foreign economic activity in the context of ensuring national and energy sustainability, developing forecasts of strategic development. It was concluded that it is necessary to reflect long-term goals and tactical tasks in program-targeted documents, expand co-operational interactions with various sectors of the economy and industries, and promote technological innovations at the state level that allow expanding industrial and production potential and ensuring faster development of the oil and gas complex. The article was carried out using such scientific methods as synthesis, analysis, generalization and comparison, as well as from the standpoint of system-functional and complex or integrated approaches. The practical significance of the results lies in the theoretical justification of the need for state regulation of the oil and gas complex in the context of digital technological changes. It is aimed at promoting domestic industry and sectoral development, stimulating the integrated introduction of innovations, and reaching outstripping economic growth rates that are ahead of the pace.
Lexical factors in non-finite complementation of continue
Authors: Podhorodecka Joanna
Published: April 2023

The study examines the usage of two non-finite complements of the verb continue: the -ing form and the to-infinitive, arguing for the importance of low level generalizations in accounting for the complement choice. The semantic import of complement constructions may vary with specific lexeme classes of both the matrix verb and the complement verb, as well as be conditioned by more general features associated with the verbs’ lexical aspect. The determinants of complement choice are characterized in terms of the aspectual construal of the complement event imposed by the two alternative constructions: conceptual proximity and distance associated respectively with the -ing form and the to-infinitive. The study relies on distinctive collexeme analysis: a statistical technique which compares the lexemes distinctive for the two constructions in order to describe the semantics of the construction by examining its most characteristic collocates.

Published: April 2023

This paper considers the rationale for taking into account and assessing the non-stationarity of the development of hydrological processes in the Volga River basin when determining the parameters of the functioning of the Volga water management system. The main purpose of the study is to identify non-stationarity in the formation of river runoff and develop methods for its assessment. The problem of constructing a dynamic-stochastic model is solved, which takes into account the non-stationarity of the formation of river runoff in different periods of time. A generalization of the dynamic-stochastic approach for the analysis and evaluation of long-term fluctuations in the inflow of river waters of the Volga River near the city of Volgograd is made. The stochastic relationship between the runoff of adjacent years is expressed by the transition function that controls the Markov process. Stationarity (non-stationarity) of long-term fluctuations in river runoff was assessed using the Fisher criterion (homogeneity of sample variances), Student’s criterion (homogeneity of sample means), Kolmogorov-Smirnov criterion (homogeneity of samples) and pair correlation (presence of a trend). The description of the nature of the flow of hydrological processes is represented by a model determined by the dynamic-stochastic approach when considering the non-stationary process of the annual flow of the Volga River. Based on the application of the concept of quasi-stationarity, the functions of the availability of the annual flow of the Volga River are obtained, which are used for a probabilistic assessment of the inflow of river waters in the Volga basin. The analysis of long-term fluctuations of the annual runoff of the Volga River made it possible to reveal that the variability of the river runoff of the studied basin has two components – deterministic and random. The deterministic component manifests itself in the change in time of the average value of the flow of the Volga River, and the random component is observed in the irregular annual deviations of the flow from its average value (norm). This approach is used in the probabilistic assessment of the inflow of river waters in the Volga river basin.

The larvae of crustaceans, including those of brachyuran crabs, are a significant part of
zooplanktonic communities constituting an ecologically important fraction of the pelagic
communities. The present study describes taxonomic studies on three megalop stages of Portunus
pelagicus (Linnaeus, 1758), Charybdis feriatus (Linnaeus, 1758) and Carcinus maenas (Linnaeus,
1758) belonging to family Portunidae collected from Indus deltaic creek system. Zooplankton
samples were collected from three locations: Shahbandar 24°15’48.083’N, 67°90’15’333’E,
Ketibandar 24°9’16.06’N, 67°27’7.64’E and Korangi creek 24°48’18.80’’N, 67°12’30.31’E
during April to October 2018. No data available on taxonomic studies of portunid megalops upto
species level from Paksitan, hence this is a first attempt to examine and to describe taxonomic
features of megalops collected in the zooplankton samples. This study will contribute to the
scientific knowledge on megalops taxonomy and identification as well as be useful for future
research by taxonomists and biologists.

Published: April 2023

Arabic gum (AG) is a dietary additive widely used in food manufacture and drugs; it has also gained popularity as herbal tea that can cure diseases such as diabetes, hypertension, and chronic kidney disease. Studies showed its antioxidant and anti-inflammatory effects. In a retrospective study design, we included CKD patients taking AG for at least three months. Data were collected over one year for each patient: age, co-morbidities, duration, amount of AG used, serum creatinine, inflammatory markers, lipid profile, blood sugar, hemoglobin A1C, and blood pressure readings. For the changes in values and trends, we compared the values individually for each patient separately. A total of 30 patients consisted of 20 males (66.7%) and 10 females (33.3%), with a mean age of 63.2 years. The mean (M) eGFR pre-enrollment in the study was 23.5 ml/min (standard deviation [SD]=15.8), and the mean eGFR at the end of the study was 26.1 ml/min (SD=18.9, p=0.56). There was a significant difference in the eGFR after using AG between diabetics (M=31.3 ml/min, SD=18.5) and non-diabetics (M=20.5 ml/min, SD=18.2, p=0.03). With a history of catheterization, there was a significant difference in eGFR between patients who had catheterization (M=31.76, SD=20.86) and patients without catheterization (M=18.36, SD=13.08, p=0.04). No significant effect on lipid profile, or CRP, yet significant effect on blood sugar control (fasting blood sugar 0.0001, and HBAa1c 0.01). In conclusion, AG is a promising natural material that affects decreasing eGFR in CKD diabetics patients.
Theory of didactical suitability: An enlarged view of the quality of mathematics instruction
Authors: Godino Juan D. , Batanero Carmen , Burgos María
Published: April 2023

Characterizing and measuring the quality of instruction is a matter of growing interest in mathematics education. Based on the notion of didactic suitability and the theoretical assumptions of the onto-semiotic approach, we develop an instrument to systematically analyze the different facets involved in a mathematics instruction process. We also explore the concordances and complementarities with instruments for measuring the quality of instruction. Thus, quantitative quality measurement efforts are complemented by another qualitative approach, focusing on the initiative and responsibility of teachers when they have to make decisions about their teaching practices. This reflective activity must be supported by specific instruments that reveal the complexity of the processes and the difficulty of achieving a balance between sometimes conflicting didactic principles.
Learning first-year mathematics fully online: Were students prepared, how did they respond?
Authors: Morton Wilmari , Durandt Rina
Published: April 2023

This paper reports on empirical results from a study that investigated first-year mathematics students’ preparedness for, and response to, online learning. With the appearance of COVID-19 in 2020, lecturers were forced to make sudden changes to the established face-to-face learning environments, and students were expected to adapt to these changes. The idea of a blended learning environment is not new, and students globally have demanded flexibility in mathematics learning environments for some time. However, the idea of a sudden change in environments, particularly to fully online, was new to most lecturers and students. Key aspects in an online environment are students’ ability to self-regulate their learning, and the availability and accessibility of technological resources. Quantitative data from the self-developed questionnaire were collected early in 2021, at a public university in South Africa, from a large sample over several modules. Results indicate students are partially prepared for learning fully online, with significant effect on performance.
Use of a Miniature Optical Engine for Age Classifying Wild-CaughtCoquillettidia perturbansin the Shortwave Infrared Region
Authors: Swab Christopher L. , Best Curtis R. , Cornine Frank H. , Segal David R. , Telford Sam R.
Published: April 2023

Near-infrared spectroscopy (NIRS), coupled with modeling and chemometrics, has been used to age grade anopheline and aedine mosquitoes; however, NIRS has not been widely used in field studies to assign mosquitoes to age classes. One reason is the relative cost of NIRS spectrometers. We developed a spectrometer system incorporating a miniature optical engine generating spectra in the shortwave infrared region, calibrated it using laboratory-reared Aedes aegypti, and evaluated its utility to age grade wild-caught cattail mosquitoes, Coquillettidia perturbans. As a refinement of the method, we compared a scoring system based on spectral data point outliers with the typical chemometrics that have been used with NIRS. This inexpensive system (<$3,600) could reliably discriminate between age cohorts of mosquitoes and has the potential for more detailed age grading. Laboratory-reared Ae. aegypti demonstrated a decline in the fraction of spectral outliers with age, and field-collected Cq. perturbans similarly demonstrated such a decline (greater in newly emerged mosquitoes) with date of collection, consistent with their univoltine demography in Massachusetts. We conclude that an economical NIRS system may be able to provide a quantitative dichotomous (young versus old) assessment of field-collected mosquito samples, and thereby may be used to complement abundance-based analyses of the efficacy of adulticiding applications.
Impact of Nonconventional Selection by Insecticides on Susceptibility of the Southern House Mosquito,Culex quinquefasciatus
Authors: Pokhrel Vivek , Ottea James A.
Published: April 2023

Mosquitoes are an important target of pest control as they vector pathogens that are associated with many debilitating human diseases. Given that mosquitoes have been selected with insecticides for over 100 years, much is known about the development of insecticide resistance associated with targeted application against populations of these insects. However, off-target selection by applications of insecticides in agricultural and residential sites also impacts development of insecticide resistance and is understudied. Similarly, the impact of selecting one life stage of mosquitoes on the insecticide susceptibility of different life stages is largely unknown. Here, we show that susceptibility to chlorantraniliprole, which is applied in rice (Oryza sativa) and sugarcane (Saccharum officinarum) fields in Louisiana, decreased (5.7- to 12-fold) in populations of Culex quinquefasciatus collected from near these fields compared with a reference field strain. In addition, application of bifenthrin by commercial application on an individual residence increased the resistance frequencies to bifenthrin in 5 nearby residential sites. These increased frequencies of resistance, as measured with diagnostic concentrations of bifenthrin, were highly correlated (R2 = 0.92) between larvae and adults, suggesting that selection of adults also confers resistance to larvae. Finally, esterase activities and bifenthrin susceptibilities were moderately correlated (R2 = 0.4 for larvae and 0.52 for adults), suggesting that multiple mechanisms (including metabolism by esterases) were associated with the observed resistance. Results from this study suggest that nonconventional selection by insecticides is a variable to consider when developing management strategies for populations of Cx. quinquefasciatus.

Mansonia are aggressive mosquito species that are abundant in aquatic ecosystems where the macrophyte plants occur. These mosquitoes are commonly found across the Amazon/Solimões River basin. However, little is known about the oviposition behavior of these species. In the present study, we registered observations on the oviposition activity of 3 species: Mansonia amazonensis, Ma. humeralis, and Ma. cf. titillans, in 5 species of macrophytes in the vicinities of the Madeira River, Porto Velho, State of Rondônia, Brazil. Overall, 197 egg batches were collected. A greater amount of egg batches was found in Salvinia molesta as compared with other macrophytes sampled. In addition, 2 new oviposition habitats were noted in Ludwigia helmintorrhiza and Limnobium spongia. These findings will be important to understand the reproductive dynamics of these mosquitoes in the Brazilian Amazon basin.

Mosquito suppression strategies based on “rear and release” of male mosquitoes are attracting renewed interest from governments, municipalities, and private businesses. These include irradiation-based sterile insect technique, Wolbachia-based technologies, and genetic modification. Each of these approaches requires the mass rearing and release of adult male mosquitoes, which typically is accomplished via a rearing facility near the release site. Although some release programs have relied on centralized rearing and shipment of adult males, adult male mosquitoes are relatively fragile, and their fitness can be diminished by temperature fluctuations, humidity, nutritional deficiencies, and other stresses that occur during shipment. Furthermore, expensive, expedited shipment is typically used to maximize the amount of adult lifetime in the field following the release. In contrast, Aedes aegypti and Ae. albopictus eggs can be desiccated and stored for long periods. They are small, and many millions of eggs can be shipped without specialized environmental conditions and using less expensive means. Here we examine a model in which mosquito eggs are centrally produced and then mailed to satellite rearing facilities. As a control, a replicate set of eggs was reared at the factory of origin. At each of the rearing sites, cloud-based software was used to track and compare rearing at the different locations. The results demonstrate similar rearing outcomes (i.e., egg hatch, immature development, and number of adult males) at each of the different sites for both species. We discuss the outcome in relation to downstream applications and potential future studies.

Se estudió la remoción del fitoplancton mediante pretratamiento con ozono en una planta piloto que capta agua de un embalse subtropical del noroeste argentino. Se analizó la variación estacional de las abundancias por grupos algales a la entrada y salida de la planta en el período 2019-2020, y la eficiencia de remoción del tratamiento en función de dos categorías de tamaños (MDL máxima dimensión lineal) y biovolumen en especies seleccionadas. La abundancia de algas al ingreso mostró diferencias estacionales con predominio de diatomeas en invierno, Criptofíceas, Clorofíceas, Dinofíceas y Trebouxiofíceas en primavera y Cianobacterias en verano. El flujo de salida de algas también fue mayor en invierno, con predominio de diatomeas, y de cianobacterias en otoño y verano. El tratamiento produjo una reducción significativa de la densidad de algas (media del 26,94%), que aumentó aún más en algunos grupos particulares: Zygnematophyceae (68,21%), Euglenophyceae (59,80%), Cianobacterias (57,87%), Cryptophyceae (53,84%), Dinophyceae (38,59%) y Chlorophyceae (28,66%). En el seguimiento se registraron un total de 326 spp, aunque sólo 126 spp tuvieron una frecuencia de aparición en al menos el 10% de los muestreos, en su mayoría con bajas densidades. La eliminación de microalgas en la planta piloto no mostró correlaciones significativas con las dimensiones celulares de las especies seleccionadas. Las medias de la clase III de MDL =31,62 ±8,79 ?m y biovolumen =4019,69 ±2711,49 ?m3 tuvieron las mayores eliminaciones por tratamiento (72,97% y 72,74%, respectivamente), aunque no fueron estadísticamente diferentes de las clases restantes. Conclusión: la capacidad de eliminación de algas por el proceso de ozonización de la planta piloto produjo una reducción significativa de la densidad algal, especialmente de Cianobacterias, Zygnematoficeae, Euglenophyceae y Cryptophyceae, que en todos los casos superó el 50%.

Multiple sclerosis is a chronic autoimmune, inflammatory neurological disease affecting the nervous system. It targets the myelin sheath of the axons and inflicts axonal degeneration. High susceptibility is seen in people of age group 20-40 years. The incidence rate is three times more in females compared to males. There are 4 types of multiple sclerosis, namely relapsing/remitting multiple sclerosis, secondary progressive multiple sclerosis, primary progressive multiple sclerosis, progressive relapsing multiple sclerosis with relapsing-remitting being the predominant type and makes up 85% of the cases. The pathogenesis of multiple sclerosis includes destruction of myelin sheath followed by formation of lesions and inflammation. Environmental factors and genetic variables play major role in development of the disease. Exposure to viral and bacterial agents can also lead to multiple sclerosis. Disease-modifying therapies (DMTs) are the most commonly employed management strategies for treating patients with multiple sclerosis. Conventional drugs like IFN-β-1a and glatiramer acetate are now being replaced by highly effective DMTs and autologous hematopoietic stem cell transplantation. Recently, there has been drastic developments in the management of multiple sclerosis, owing to the discovery of more tailored and individualized treatment protocols catering specifically to patient needs.

Kegiatan pengangkutan galon air mineral di AQUA Home Service Cilegon masih dilakukan secara manual tanpa menggunakan alat bantu. Pada saat pekerja menangani galon-galon air, masih terdapat postur kerja yang berisiko. Hal ini menyebabkan beberapa pekerja mengalami keluhan Musculoskeletal Disorders (MSDs). Adapun tujuan dari penelitian ini yaitu mengidentifikasi pre­va­lensi keluhan MSDs, mengetahui tingkat risiko postur kerja, dan mem­beri­kan usulan perbaikan yang berpotensi menurunkan risiko MSDs. Pengukuran tingkat risiko postur kerja menggunakan metode RULA dan REBA serta diolah dengan bantuan software ErgoFellow. Dari hasil kuesioner Nordic yang dibagikan pada total empat pekerja, diketahui bahwa keluhan pada punggung bawah dan bahu dirasakan oleh semua pekerja. Hasil penilaian risiko postur kerja pada proses pengangkatan dan membawa galon, menunjukkan perlunya perubahan pada postur kerja (skor RULA 7 (risiko tinggi); skor REBA 8 (risiko tinggi)). Perbaikan yang diusulkan yaitu alat bantu angkut galon berupa troli yang sesuai dengan ukuran antropometri sehingga nyaman digunakan, memperbaiki postur kerja, dan berpotensi menurunkan MSDs. Hasil simulasi menggunakan CATIA V5R21, menunjukkan bahwa penggunaan alat bantu angkut galon menurunkan level risiko RULA dari 7 ke 3 (risiko rendah). Rancangan alat bantu galon yang diusulkan diharapkan dapat diimplementasi­kan di lapangan dan membantu menurunkan risiko MSDs.

This study testedthe capability of Civil3D to design acarriageway using FMWH Manual. Forthis purpose, the guidelines outlined in the manual were accommodated. The route under consideration is a proposed dual carriageway alignment at Modibbo Adama University (MAU) Yola, Adamawa State, Nigeria. Methodology focused on field work, data acquisition, and roadway alignment design. Data for this project was obtained directly from the field using conventional ground survey method, Google Earth, GARMIN GPSMAP64 Hand Held GPS, and Kern-Swiss K1-M 292272 Theodolite. Reduce level was computed using Microsoft excel and the output was imported into the design software (Autodesk Civil 3D V.2023) as a dot csv (.csv) data file known as PENZD.csv.A simple horizontal circular curve with a radius of 200m was designed at chainage 0+268.55 to 0+290.41 between two tangents. Two Sag curves at chainages 0+160.95 and 0+655.33 were designed for the vertical alignment. A trapezoidal channel was provided to discharge storm water and also, a single cell box culvert to be sited at chainage 0+524 to 0+532.5. Equally, a pipe culvert was proposed at 0+722 to 0+723. QR Code for data used is also presented. The results indicate that the designed alignment was adequate and economical based on FMWH Manual.

Thegeneration of electricity is critical to the expansion of the economy and the improvement of people's standard of living. Scientists from all over the world find themselves increasingly aware of the impact of power plants as a result of the expanding human population and the ever-increasing demand for dependable sources of energy. The construction of about 95% of power plants is carried out in accordance with energy performance requirements, which take into account only the first law of thermodynamics. It is not possible to use the first equation of thermodynamics to compute the actual effective energy loss since it does not differentiate between the quantity and quality of energy. Calculating energy and exergy based on the properties of the steam was at the focus of the investigation into the energy and exergy efficiency of the plant. According to the findings, an increase in the parameters governing the scalding steam caused an increase in both the system's efficiency and its enthalpy. The boiler has the highest exergy efficiency (59.66%), whereas the condenser has the highest energy efficiency (48.10%). The investigation proved beyond a shadow of a doubt that the boiler was the principal cause of the system's irreversibility.
