The use of concrete for basic construction materials today is indeed increasing rapidly along with the development of construction construction.Only a concrete quality of 19.3 MPa (fc '= 25 MPa) was considered in this study. Since cement, aggregates, sand and water are extracted from nature, they must be limited. So in this study using additional material clam shells. One of them is shells, shellfish waste or shells are usually only used as decorations or toys so that there is still a lot of waste wasted. Inside the shell, the clam contains pozzolan chemical compounds, namely lime (CaO), aluminum oxide and silica. It can be expected to improve the quality of concrete.
As a result of compressive strength test by changing the clamshell to 0%, 10%, 20%, 30%, 40% and 50%, the average compressive strength value of 0% (ordinary concrete) was 15.81 MPa. The addition of a 10% clam shell results in an average compressive strength value of 20.58 MPa. For the addition of clam shells by 20% obtained an average compressive strength value of 23.37 MPa. 30% yields an average compressive strength of 40.31 Mpa, to 40% of 29.12 Mpa. As for the addition of 50% clam shells, the average compressive strength value is 24.79 Mpa. Thus it can be concluded that the addition of clam shells 30% compressive strength value is higher than the compressive strength value of concrete with the addition of clam shells 0%, 10%, 20%, 40%, and 50%The flexural strength test value in terms of the maximum average moment on the beam for each variation of the test specimen is maximum moment value 75.02 kN.m for 0% variation, maximum moment value 62.52 kN.m for 10% variation, maximum moment value 68.77 kN.m for 20% variation, maximum moment value for 30% variation 62.52 kN.m, 40% variation at maximum moment value of 62.52 kN.m. Therefore, the percentage of specimens that can withstand the highest load in the flexural strength test is 0% and the maximum moment value is 75.02 kN.m.

Published: September 2023

Increased branch canker and dieback were observed in commercial avocado (Persea americana) orchards in Sicily, Italy. Surveys were conducted in 2021 and 2022 on 11 orchards to investigate etiology of the disease. Seventy-five plants from four orchards, showing branch canker and dieback, were sampled. Isolations from woody diseased tissues revealed the presence of fungi (Botryosphaeriaceae). Identification of the isolates was achieved by morphological and multi-loci phylogenetic analyses (Maximum Parsimony and Maximum Likelihood) of the ITS, tef1-α, and tub2 loci. Botryosphaeria dothidea, Lasiodiplodia citricola, Macrophomina phaseolina, Neofusicoccum cryptoaustrale, and Neofusicoccum luteum were identified. Representative isolates collected from the orchards, characterized based on the tub2 locus and identified as N. parvum, were excluded from this study, since this species has already been reported in our territory. Pathogenicity tests were conducted on potted, asymptomatic, 2-year-old avocado trees using mycelial plugs. These tests showed that all the Botryosphaeriaceae species characterized in this study were pathogenic to avocado. This is the first report of L. citricola, M. phaseolina and N. cryptoaustrale causing canker and dieback on avocado trees, and is the first record of these fungi causing branch disease on avocado in Italy.

El objetivo de la investigación fue identificar los principales temas trabajados por los investigadores con respecto a la educación superior peruana durante y después de la pandemia COVID-19.Considerando los postulados de Kitchenham (2004), Okoli y Schabram (2010),Liberati et al., (2009) y Page et al., (2021) el trabajo se aborda mediante una revisión sistemática de los artículos científicos publicados desde el año 2021 hasta el 2023 en las bases de datos Redalyc, Dialnet yScielo,en el ámbito de la educación superiorperuana. Para ello, se siguió un protocolo de ochos pasos y formularon dos interrogantes que delimitaron el alcance de la investigación. Los descriptores usados fueron: Educación Universitaria y Perú. Adicionalmente se establecieron cinco criterios de inclusión y exclusión a fin de depurar la información descartando los artículos que no contenían información suficientemente relacionada con el objetivo de la investigación. Los resultados mostraron la prevalencia de estudios dirigidos al tema de la virtualidad 33.33% del total. Mientras que un 20% aborda los modelos de aprendizaje. Con un 13,33% se ubican los relativos competencias y perfiles profesionales de los egresados. Mientras que en el porcentaje restante 33,33% se encuentran temas diversos: ética, acceso de las minorías a la educación superior, estrés académico, desesperanza aprendida y becas.Las temáticas abordadas, por demás diversas pero concatenadas, constituyen retos tanto para la gestión universitaria peruana como para los organismos del Estado encargados de dictar lineamientos en torno a la educación superior en el país, en un escenario pos pandémico por demás complejo, con más interrogantes que certezas. Pero también señalan los tópicos de relevancia e interés para la comunidad universitaria.
A Numerical study on the effect of solidity on the performance of Transverse Axis Crossflow Tidal Turbines
Authors: Gallagher Rónán , Frost Carwyn , Schmitt Pál , Young Charles 
Published: September 2023

This paper presents a three-dimensional numerical study employing an actuator line model to investigate the effect of turbine solidity on the performance of a Transverse Axis Crossflow Turbine (TACTs). Transverse Axis Crossflow Turbines have a low rectangular form and are ideally suited to relatively shallow tidal and riverine sites due to their ability to handle bi-directional flow intake. Lift based TACTs are not well understood due to their complex hydrodynamics when the downstream sweep passes through the wake produced by the turbine shaft and the upstream sweep. The blade loading, hydrodynamics and ultimately power produced during the downstream sweep depends on the number of blades and turbine solidity. This numerical study is carried out using OpenFOAM and replicates planned fieldwork where the power and in-service blade loading will be monitored as a function of turbine solidity. Turbine solidity is a dimensionless parameter that measures the proportion of blade area to the projected turbine frontal area. Turbines achieve peak performance at an optimum solidity and tip speed ratio. Solidity can be varied by changing the number of blades or changing the turbine radius. An increase in solidity causes the peak performance to reduce and shift to a lower tip speed ratio albeit with a greater torque.
This paper also explores the effect that maintaining turbine solidity has on turbine performance over a range of typical inflow velocities. Turbine solidity is held constant by varying both the number of blades and turbine diameter. Iso-solidity has been investigated for horizontal axis wind turbines but little is known about the effect of maintaining turbine solidity on TACT performance.

The Effect of Endorphin Massage on the Intensity of Back Pain in Mothers During Active Phase I in Labor in Tegallega Village, Warungkondang District, Cianjur Regency, Indonesia
Authors: Rika Dwi Mustika  , Mustari Paramita 
Published: September 2023

Childbirth is a physiological process or the process of expelling viable products of conception from the uterus to the outside world, thus enabling the mother to give birth to her fetus through the birth canal. There are several aspects related to pain during labor and can affect the birth process itself. Treatment uses non-pharmacological methods such as relaxation, warm compresses, yoga and one of which is using massage methods to reduce pain, one of which is back massage and endorphin massage. This study aimed to find out the effect of endorphin massage on the intensity of back pain in laboring mothers during the first active phase in Tegallega Village, Warungkondang District, Cianjur Regency. This study is an experimental research with a one group pre-test post-test design. This research only involves one group of subjects who will be observed before and after the intervention. The average intensity of pain before endorphin massage was given to mothers giving birth was 8.23. Meanwhile, the average value of the intensity of back pain in women giving birth after being given endorphin massage was 7.23. This shows that the intensity of back pain in mothers giving birth during the first active phase before endorphin massage was given to mothers giving birth during the first active phase in Tegallega Village decreased. There is an effect of giving endorphin massage on the intensity of back pain in mothers giving birth during the first active phase.
Are there sex differences in spatial reference memory in the Morris water maze? A large-sample experimental study

Published: September 2023

AbstractSex differences have been found in allocentric spatial learning and memory tasks, with the literature indicating that males outperform females, although this issue is still controversial. This study aimed to explore the behavior of male and female rats during the habituation and learning of a spatial memory task performed in the Morris Water Maze (MWM). The study included a large sample of 89 males and 85 females. We found that females searched slightly faster than males during habituation with a visible platform. During learning, both male and female rats decreased the latency and distance traveled to find the hidden platform over the days, with males outperforming females in the distance traveled. Females swam faster but did not find the platform earlier, suggesting a less directed navigational strategy. Both sexes increased time spent in the target zone over the days, with no sex differences. Although females swam more in the periphery during the first days of the task, both sexes decreased the time spent in this area. Finally, only males increased swimming in the pool's center over the days, spending more time than females in this area across the entire training. In conclusion, we need to register several variables in the MWM and analyze path strategies to obtain more robust results concerning sex differences. Research on spatial learning should include both sexes to achieve a more equitable, representative, and translational science.
