Authors: Manzi Leites Hernán Alejandro
Published: January 2024

La comprensión de lo histórico por medio de la “revivencia” en Dilthey confluye con la idea de re-enactment en la teoría de la imaginación histórica de Collingwood a través de la autognosis. Este conocimiento de sí constituye la actividad primordial de la comprensión histórica y es llevado a cabo por el individuo que comprende de acuerdo con los significados vitales y sociohistóricos de su época. Así, las tradiciones del empirismo y del idealismo se acercan en aras de una reflexión sobre la actividad efectiva del historiador. Se analiza, entonces, cuál es el rol de la autoconciencia en el conocimiento humano, atendiendo a las diferencias entre la psicología de ambos pensadores.

Published: January 2024

ABSTRACT Understanding the green dwarf coconut palm development is essential to improve its management. This study aimed to characterize and understand the seasonality of the green dwarf coconut palm development and yield under rainfed and irrigated conditions in the northeastern region of the Pará state, Brazil. The longitudinal and transverse diameters, fruit mass and yield, in addition to the number of live leaves, live bunches, fruits of the bunches nº 11 and 14 and female fowers were monitored. The coconuts between the bunches nº 20 and 22 showed larger dimensions and biomass (fresh and dry). The partition of the production components varies according to the time of the year, with the liquid albumen mass, which is a component of greater commercial focus, being higher in the rainy season, with lower percentage losses in the irrigated cultivation. The meteorological seasonality plays a key role in fower dropping and fruit abortion, directly contributing to the amount of produced fruits.

Abstract Introduction: Chronic kidney disease is usually asymptomatic, and its diagnosis depends on laboratory tests, with emphasis on serum creatinine and proteinuria. Objective: To assess knowledge on the role of serum creatinine as a biomarker of kidney function in a sample of the Brazilian population. Method: Cross-sectional observational study conducted in São Paulo (SP, Brazil), in which a random adult population was interviewed. Results: A total of 1138 subjects were interviewed, with a median age of 36 years old (27–52); 55.1% were female. Regarding the “creatinine” biomarker, 40.6% stated they had never performed such a test. When asked about their knowledge on the usefulness of this exam, only 19.6% knew its function. The other responses were “I don’t know” (71.6%), evaluating heart function (0.9%) and liver function (7.8%). Of those who reported they had already taken a creatinine test, only 29.4% correctly identified the role of creatinine. When dividing the groups into “knows” and “does not know” the function of creatinine, a statistically significant difference (p < 0.05) was observed regarding level of education, female sex, being a healthcare student/worker, having ever measured creatinine, knowing someone with kidney disease and older age. In the multivariate analysis, the main variable related to knowing the creatinine role was having previously taken the test (OR 5.16; 95% CI 3.16–8.43, p < 0.001). Conclusion: There is a significant lack of knowledge about creatinine and its use in checkups. The results indicate that greater efforts are needed from healthcare professionals to raise awareness on the role of serum creatinine.

RESUMO O empreendedorismo feminino (EFEM) vem sendo apresentado como impulsionado principalmente pela necessidade, abrangendo processos sociais de gênero que levam as mulheres a empreender como meio de encontrar independência, autoconfiança, alívio financeiro ou um estilo de vida mais equilibrado. Pesquisas existentes também identificaram diferenças nas motivações e barreiras ao autoemprego feminino em países em desenvolvimento versus países desenvolvidos. Assim, o artigo propõe um quadro integrador combinando a Imersão Mista e a Teoria Institucional para analisar o processo empreendedor das mulheres imigrantes, adotando uma lente multiteórica para aprofundar a compreensão das práticas empreendedoras das mulheres no exterior e sanar as inconsistências da imersão de Granovetter.
Wall and pillar drains in puddle clay embankment dams
Authors: Brown Alan John , Brown David Henthorn , Tudor Samuel , Reynolds Adam
Published: January 2024

Puddle clay core embankment dams were built prior to the use of rolled clay core dams and comprise a large proportion of UK dams, with the dams relying for their watertightness on the addition of water to (puddle) the clay until it has an undrained shear strength of around 10 kPa, and thus has increased ability to deform without cracking. Such dams sometimes had early forms of unfiltered drains, comprising coarse cobbles, in the downstream shoulder, either to assist construction and/or to lower the phreatic surface and improve the slope stability once the reservoir is in operation. These drains are separate from foundation drains dealing with springs encountered in the foundation excavation and drains to deal with surface runoff. This paper gives examples of such drains in dams constructed between 1863 and 1940. These drains were installed prior to the development of classic filter design rules and tools to analyse seepage. This is important as the drains have no filter, and are thus vulnerable to internal erosion which, if not detected, could lead to failure of the dam. These drains may also be the true root cause of historic incidents at these dams, due to embankment fill materials washing into the drain and creating sinkholes.

Published: January 2024

Background: Cardiovascular disease (CVD) risk factors such as sedentary behaviour, decreased physical activity (PA), and low cardiorespiratory fitness lead to an increased and accelerated risk of cardiovascular disease and mortality. Medical students tend to adopt sedentary lifestyles due to a demanding curriculum. This may have a negative effect on CVD risk factors and cardiorespiratory fitness levels of medical students.
Objectives: To compare physical activity and cardiorespiratory fitness levels in a cohort of third- and fifth-year undergraduate medical students in a South African university.
Methods: Data from 123 third-year and 139 fifth-year medical students in the Graduate Entry Medical Programme (GEMP) at the Faculty of Health Sciences, University of the Witwatersrand, were collected. Measurements included CVD risk factors, height, weight, blood pressure, waist circumference, cardiorespiratory fitness, physical activity vital signs and pre-participation health screening questionnaires. Descriptive statistics were presented as mean ± standard deviation or median [interquartile range] depending whether the data were normally distributed or not.
Results: Both groups had low cardiorespiratory fitness when compared to norm values (GEMPI VO2 peak was 29.1 ± 5.9 ml.kg-1.min-1 and GEMPIII VO2 peak was 30.0[11.0] ml.kg-1.min-1). Most participants did not meet WHO physical activity requirements (GEMP I: 72%; GEMP III: 78%). There were significant differences in BMI (p=0.046), diastolic blood pressure (p=0.034) and VO2 peak (p=0.00001) between students meeting and not meeting WHO physical activity requirements (p<0.05).
Conclusion: Third- and fifth-year medical students at a South African university fail to meet recommended WHO physical activity levels and are below cardiorespiratory fitness norms. Therefore, medical institutions should promote and implement targeted physical activity interventions to reduce the prevalence of low fitness levels and the associated health hazards among their students.

Study of heat and mass transfer in a channel with fins based on a triply periodic minimal surface
Authors: Popov Andrey I. , Eremin Anton V. , Kechin Nikita N.
Published: January 2024

Presents a methodology for studying heat and mass transfer in the channels of heat exchange devices, where fins made in the form of a Schwarz Primitive triply periodic minimal surface (TPMS) are used to intensify heat transfer. The solution of the heat and mass transfer problem is carried out using the finite element method in the Fluent module of the ANSYS software package. The work examines the influence of the initial flow velocity, as well as the thickness of the TPMS fins on the pressure loss and temperature characteristics of the flow. The study showed that TPMS fins enhance heat transfer and create turbulent flows in close to the TPMS frame. The pressure loss in the channel increases according to a power law with increasing initial flow velocity. The results obtained in this study demonstrate the potential of using TPMS in heat exchange devices and open many prospects for further research.

The modern world is characterized by a binary opposition of globalization and regionalization. The erosion of national and regional identities, historical traditions, and cultural continuity has become the reverse side of world integration. In this regard, scientific research devoted to individual regions is being activated. The article highlights historical and architectural environment of small and medium-sized towns in the Nizhegorodskoe Povolzhie region, its formation in the late 18th – early 20th centuries and its further transformation. The historical and architectural environment is interpreted as a phenomenon of the region architectural and urban culture. It is considered in the context of topical historical and theoretical problems of architecture and urban planning: problem of traditions and innovations; problem of mass and unique; problem of style and image; problem of global and identical. The first part of the article analyzes the properties of the historical and architectural environment that determined its visual harmony at the beginning of the 20th century.

Published: January 2024

Background: Jaundice is the single most common abnormal physical finding in the first week of life. Jaundice is observed during the 1st week of life in approximately 60% of term infants and 80% of preterm infants. The most common used methods of treating hyperbilirubinemia are phototherapy, exchange transfusion and pharmacological therapy. Potential but lesser known complication of phototherapy is hypocalcaemia. Our objective is to study the effect of phototherapy used for the management of   hyperbilirubinemia and   its   consequent effect on calcium homeostasis.

 

Methodology: This study was conducted on total 180 neonates admitted to Neonatal intensive care unit of a tertiary care center of ‘Steel city of Central India’. All study participants are included in two groups. One group included   45 preterm neonates (gestational   age >32 week but <37 week) and  other group included  45  full term neonates (gestational   age >37 week). In   addition, 45 neonates served   in   each   group as control. All had hyperbilirubinemia. The controls were fully matched with the study group. All the neonates included in the study group required management with phototherapy. The neonates in the control group were managed without phototherapy. Total Serum bilirubin levels and serum calcium levels were checked before and after phototherapy.

 

Result: The mean total serum calcium showed a statistically significant fall after exposure to phototherapy in the study group. The commonest complication observed after phototherapy was loose stools and rashes in preterm and full term neonates.

 

Conclusion: In neonates with hyperbilirubinemia serum calcium level significantly decreases due to phototherapy. Preterm new-borns suffer more from hypocalcaemia than full term new-borns after receiving phototherapy.

For the effective development of the agricultural sector, solving the problems of timely and sufficient power supply is relevant. Due to the absence or inefficiency of the wiring of centralized power supply systems in remote areas, fertile lands are gradually going out of circulation. Based on the study of the experience of developed countries in solving the above problems, the corresponding conclusions were made on the transfer of mobile agricultural machinery to electric drive, the development and production of mobile mini-electric tractors for processing and harvesting in local conditions, mobile power stations based on renewable energy sources for remote territories.

 

In the agricultural sector, electric energy is mainly consumed for irrigation and electric drive of various equipment and installations. For example, for the introduction of drip irrigation and electric tractors in remote areas from centralized power supply lines in Uzbekistan, the mobile method of power supply is considered effective. The developed prototype of the Solar-Wind mobile power plant can generate an average of 4.5-4.7 kWh in the daytime, and 0.8-1.0 kWh of electric energy in the evening hours. The annual production of electric energy is more than 20,000 kWh of electric energy. Taking into account the return of fertile lands into circulation, and the cost of the resulting crop, the payback of the station does not exceed 4-5 years.
