The concentrations of lead (Pb2+), copper (Cu2+), zinc (Zn2+) and chromium (Cr2+) in adult Zonocerus variegatus (L.) collected. from six different locations within Abeokuta metropolis as well as in the .soils and food plants on which the grasshoppers w re II ted were determined. Z. variegatus accumulated heavy metals in its i body at concentrations significantly (P<0.05) affected by location of collection. Insects collected from lta-Oshin Industrial Estate and Mechanics’ Village had. high concentration of Pb 2+ 0.30 and 0.166mg/100g, respectively) which differed significantly from values for other 1 cations. Insects from the University Farm and Petrol Station had high concentration of u (0.083 and 0.0811. mg/100 g, respectively) which were, however, statistically comparable to values for other locations. Collections from locations with more than on ho t plant species had higher proximate values than those of locations with single ho t plant species. By these findings, it was confirmed that Z. variegatus, like other arthropod could accumulate heavy metals in its body. Thus, there is need to closely monitor the concentration of metals in the body of Z. variegatus especially in the areas where the in ct is an item of human diet.

Published: September 2023

Eighteen improved and two ‘local varieties ‘of maize (Zea mays L.) were evaluated for resistance to infestation by the larger grain borer, (LGB), Prostephanus truncatus (Horn);’ in the Entomology Research Laboratory of .the Department of Crop Protection and Environmental Biology, University of Ibadan, Oyo State, Nigeria at 28±1°C and 79-82% RH. -Sixty grammes of each variety were weighed into 250cm3 capacity Kilner jars and infested with 10 pairs of adult P. truncatus that were 1-5 days old. On the 40th day, all insects were collected, the maize grain dust sieved using a mesh of 0.25mm size and then ‘weighed. The’ grains were weighed and sorted into, damaged and undamaged categories and percentage damage computed, Other data recorded were the percentage grain weight loss, adult mortality and final population of adults. The study was conducted using completely randomized design and the test varieties were compared with standard using Dunnett’s t-test. The weighted average of scores generated from the five damage parameters was used to place the .varieties into one, of four rating for resistance to LGB. In addition, cluster analysis was done on the rated parameters using the centroid. hierarchical system. The results indicated that ICZBC2-B (KUI414) was highly resistant; TZBR-Ses-3C3, TZBR-Ses-IC3-Y, TZBR~Syn-YC2′ Oba Super-I and Oba Super-l l were resistant; ‘TZBR-Eld-3C2, Ama-TZBR-WC1′, TZBR-Ses-3C4-Y’ Ak- 9528-DMR-SR, Acr.91-Suwan-ISRC were moderately resistant, while others were susceptible. The mechanisms of resistance identified were antixenosis ‘and antibiosis, and the basis of resistance, were grain hardness and starch content. The resistant varieties could be used in combination with other control options in LGB-endemic areas.

Published: September 2023

Some cowpea [Vigna unguiculata (L.) Walp.] accessions, from different locations in Nigeria, and advanced breeding lines obtained from the International Institute of Tropical Agriculture (UTA), as well as winged bean [Psophocarpus tetragonolobulus (L.DC.) ] were screened for resistance to the cowpea bruchid, Callosobrucus maculatus (F.). IT90K-277-2 and IT90K-76 were the resistant standards while Ife Brown was the susceptible standard. The seed lots (20 g each) were infested with three pairs of newly emerged adults and the number of eggs laid was counted at 5 days post-infestation. F1 progeny were counted and from the values and the median developmental period, susceptibility indices were calculated. The number of emerged adults was also expressed as a percentage of the total number of eggs laid. The winged bean lines EM-WB-l, KC- 02E-l, and KC-02E-3 showed antibiosis (evidenced by low F1 progeny and low susceptibility index) at levels stronger than or comparable to those of the resistant standards. No cowpea line matched IT90K-277-2 and IT90K-76 in resistance to cowpea bruchid but three lines (ENU-AB-6, ENU-MB-8, and ENU-OG-4) were as susceptible as Ife Brown.

Authors: Koda Yusuke , Ohmi Norichika , endo hiroaki , Harada Hiroshi
Published: September 2023

This paper performs a first wideband indoor channel measurement at the 105 GHz sub-terahertz (sub-THz) band and analyzes the multipath characteristics in terms of the omnidirectional path-loss and angular characteristics. The measurement campaigns with the 4 GHz bandwidth are performed focusing on indoor short-range communication scenarios in a conference room, corridor, and office room, which have been considered in the primary 60 GHz communication systems standardized by the IEEE 802.15.3c/11ad. Moreover, to draw full understanding to scale the 60 GHz indoor channel models and 60 GHz system designs for the 105 GHz band, we also conduct 60 GHz channel measurements in the same environment with few modifications in the channel-sounding system and performed the comparison between these two bands. Based on these measurements, we demonstrate the affinity that exists between 105 GHz and 60 GHz bands in terms of path loss exponent and angular characteristics of multipath components, shedding light on the hypothesis that several system designs of the 60 GHz communication systems (e.g., beam switching for non-line-of sight conditions) can be applied to the 105 GHz sub-THz communication systems.

Label Wise Significance Cross Entropy
Authors: Jin Zhiyong
Published: September 2023

In the process of machine learning, models are essentially defined by a group of parameters in multiple layers. The parameters are learnt in a process of optimization of the loss function which measures the differences between model output and expected outputs (labels). Normally, the expected class digit is expected to be 1 and the other digits are 0s. All the digits are contributing to the loss function in the cross-entropy loss function. If the number of classes is high, the total number of 0 digits is much larger than the number of 1 digit, and the total loss of 0 digits would be higher than the total loss of 1 digit loss. The direct result is the loss does not conform with the object of the optimization. This paper introduced Label Wise Significance Cross Entropy (LWSCE) as the loss function in model training for effectively allocating the weighted loss function on the classes bearing significant differences between model output and expected output and ignoring the minor differences of 0 digits if the differences are not significant enough. This method was experimented on CIFAR10 and CIFAR100 dataset training. The experiments of cross-entropy, cross-entropy with label smoothing and LWSCE were carried out in this paper. The result shows LWACE outperforms better than the other loss functions in CIFAR100 dataset.

O esgoto contém grande diversidade de microrganismos, incluindo patógenos como os vírus, sendo, portanto, um meio propício para identificação da circulação de doenças infectocontagiosas – técnica conhecida como wastewater-based epidemiology (WBE). A WBE se mostra uma poderosa ferramenta de saúde pública para rastrear e sinalizar a situação epidemiológica da população, visto que as partículas virais do
SARS-CoV-2 podem ser expelidas nas fezes e urina dos contaminados antes mesmo do surgimento de sintomas e do diagnóstico clínico de COVID-19. Este estudo apresenta uma revisão de literatura sobre a presença de SARS-CoV-2 e outros vírus no esgoto doméstico e as possibilidades de remoção em estações de tratamento de esgoto (ETEs) convencionais e avançadas, bem como as técnicas de concentração e detecção em amostras ambientais. Ao final do artigo, foi apresentada uma análise econômica da aplicabilidade da WBE como instrumento de predição epidemiológica da COVID-19 em um município brasileiro.

O reúso de água é uma possibilidade para redução de pressões hídricas em locais com usos do solo e da água voltados para agropecuária, como na Unidade de Planejamento e Gerenciamento de Recursos Hídricos dos Afluentes Goianos do Baixo Paranaíba (Goiás/Brasil). Assim, realizou-se uma avaliação do potencial de reúso agrícola a partir do levantamento da oferta de água para reúso proveniente de Estações de Tratamento de Esgoto (ETEs) e da demanda hídrica necessária para áreas irrigáveis na UPGRH em estudo. Em seguida, avaliou-se a qualidade dos esgotos sanitários tratados segundo Interáguas, além de uma análise econômica. A aplicação do reúso se mostrou possível atendendo à demanda de irrigação no entorno das ETEs. Caso as diretrizes do Interáguas fossem reguladoras, as ETEs precisariam melhorar o seu sistema de tratamento. O transporte da água de reúso possui um custo superior ao da cobrança pelo uso da água na agricultura, o que dificulta a institucionalização da prática do reúso.

Published: September 2023

Kehadiran bisnis ritel modern dalam format mini market menjadi pilihan baagi masyarakat untuk melakukan aktivitas belanja sekaligus menjadi pesaing bagi bisnis ritel tradisional. Adapun faktor-faktor yang dapat mempengaruhi persaingan diantara bisnis ritel baik modern maupun tradisional adalah dari segi permodalan, kegiatan promosi, pelayanan gerai, ancaman pesaing baru, kekuatan tawar menawar baik pemasok maupun pembeli serta rivalitas diantara sesama  pelaku bisnis ritel. Pentingnya kinerja pelayanan dalam bisnis ritel diasumsikan dapat menjadi daya tarik minat beli pelanggan, namun yang masih menjadi topik perdebatan adalah persepsi yang berbeda dapat muncul dari sisi pelanggan dan karyawan gerai, bahkan  dari pelanggan yang sama. Munculnya perbedaan persepsi mengenai kinerja pelayanan tentunya akan memicu terjadinya perbedaan persepsi nilai pada masing-masing pelanggan. Jika pelanggan mempersepsikan bahwa nilai yang mereka rasakan selama berbelanja memuaskan maka dapat memicu terjadinya minat beli di masa yang akan datang. Metode penelitian yang digunakan adalah kausalitas dengan tujuan meneliti hubungan antara kinerja pelayanan terhadap minat beli melalui mediasi nilai pelanggan. Populasi merupakan masyarakat kota Pontianak yang berbelanja di gerai minimarket dan sampel ditentukan menggunakan metode accidental sampling. Dari hasil tabulasi, uji validitas, dan uji reliabilitas ditentukan jumlah sampel yang lolos sebanyak 172 responden dimana selanjutnya diolah menggunakan AMOS. Hasil penelitian menunjukkan bahwa variabel kinerja pelayanan tidak berpengaruh terhadap minat beli, akan tetapi berpengaruh terhadap nilai pelanggan, sedangkan nilai pelanggan berpengaruh terhadap minat beli. Sehingga dapat dikatakan kinerja pelayanan yang diberikan karyawan gerai minimarket harus memiliki nilai yang berarti bagi pelanggan jika ingin meningkatkan minat beli pelanggan di masa yang akan datang. Pelaku bisnis minimarket harus berupaya menciptakan nilai bagi pelanggan seperti memperhatikan kualitas produk, kesesuian harga, dan memberikan perhatian yang tulus dalam melayani pelanggan.

The Vicious Relationship between Apathetic Political Behaviour and Citizen Quiescence in Nairobi County
Authors: Mutuku Richard Kyalo , Owuoche Solomon Otieno , Jonyo Fred Opiyo
Published: September 2023

Voter apathy is a growing phenomenon in Kenya. Voter turnout since the Constitution 2010 was enacted has been falling drastically. In the 2013 general elections, the voter turnout was 86%, and the turnout dropped to 78% in the August 2017 elections. Further, in the 2022 general elections, numbers dropped to 64%. More significantly, the number of young people registering to vote in the 2022 general elections dropped by 5.27% compared to 2017. This apathetic political behaviour among Kenyan voters has far-reaching implications not only for democratic practices in Kenya but in governance, particularly for demand for public accountability. In this study, the researchers aimed to establish whether a relationship exists between apathetic political behaviour and citizen quiescence (citizen inaction) in demanding public accountability. Citizen quiescence is operationalised to mean general disinterest, lethargy, or unwillingness to participate in civic duties. The researchers hypothesised a direct relationship between apathetic political culture and citizen quiescence due to weak institutions and diminishing public trust in Kenya. To establish this relationship, the researchers surveyed a sample of 100 respondents drawn from Nairobi City County using a multi-stage sampling technique. The test results for linear regression analysis were R(98) = 0.841, p<0.05, R2 .703, demonstrating a positive linear relationship between apathy and citizen quiescence among Kenyans. In other words, as citizens became more apathetic in participating in democratic processes, their quiescence in demanding public accountability also increased. Besides, it was established that all factors held constant; apathetic political behaviour could explain 70.3% of citizen quiescence in Kenya at a 95% confidence level. The significance of this study was to demonstrate the necessity of civic engagement in public accountability to reduce pilferage and misappropriation of public resources

Published: September 2023

The raw material for making springs must have mechanical properties following the spring standards because the spring was receiving a dynamic load. This study aimed to improve the mechanical properties of the metal used as a material for making leaf springs. The material used is JIS SUP 9 steel which has a carbon content of 0.52-0.6%. The method used in this research is quenching and quench-tempering heat treatment. The used cooling medium was water, and the tempering temperature was at 300 °C. The mechanical properties of each specimen were tested by Vickers hardness and tensile test. The best heat treatment for material preparation is a quench-temper process, and the result was met with the manufacture of leaf spring. The findings explained that the hardness and tensile strength values were 504 HVN and 1555 N/mm2, respectively. This study could be a new insight for the leaf spring manufacture in the automotive industry.

Red chili is a food ingredient that is widely consumed and grown in Indonesia. Prices fluctuate greatly due to many factors. Post-harvest handling of chili can help farmers from losses and can maintain price stability in the market. The easiest post-harvest handling is drying. In this study, chili drying was carried out using a dryer with a rotary system. The dryer is designed in the form of a mechanical rotating drum driven by an electric motor. Hot air from LPG combustion is passed forcibly across the drum using a blower. Drying was carried out for 6 hours with a capacity of 3 kg of fresh red chilies at 60 oC, 70 oC and 80 oC. Drying at a temperature of 60 oC produces a high water content of 18.2 % with a weight loss of 80 %, the texture of the chili is still wet and soft with a bright red color. At a drying temperature of 70˚C the moisture content is quite low, namely 11.22 %, weight loss is about 87.2 %, the texture of dry chili is brightly red colored, while at a temperature of 80 ˚C the water content is low 9.1 %, the weight loss is high 90 %, dry chili texture with brown color.
Ostensible Metzler Linear Uncertain Systems: Goals, LMI Synthesis, Constraints and Quadratic Stability
Authors: Krokavec Dušan
Published: September 2023

This paper deals with the design problem for a class of linear continuous systems with dynamics prescribed by the system matrix of an ostensible Metzler structure. The novelty of the proposed solution lies in the diagonal stabilization of the system, which uses the idea of decomposition of the ostensible Metzler matrix, preserving the incomplete positivity of the system during the synthesis. The proposed approach creates a unified framework that covers compactness of interval system parameter representation, Metzler parametric constraints, and quadratic stability. Combining these extensions, all of the conditions and constraints are expressed as linear matrix inequalities. Implications of the results, both for design and for research directions that follow from the proposed method, are discussed at the end of the paper. The efficiency of the method is illustrated by a numerical example.
Extent of Inhibition of Malonic Acid on the Fermentation of Soursop Juice: A Thermodynamic Evaluation
Authors: Ogbebor C. , Egharevba F.
Published: September 2023

The fermentation of soursop juice as substrate by Saccharomyces cerevisiae (yeast) was investigated to obtain certain useful thermodynamic parameters. This was achieved by the determination of the effects of temperature, substrate and inhibitor on the rate of carbon (IV) oxide (CO2) production. The extent of inhibition was examined by the addition of malonic acid inhibitor. The results indicate that the rate of fermentation of soursop juice increased in proportion with temperature (optimum 36oC), substrate (optimum 50%v/v) and malonic acid (optimum 30%v/v) up to a limit and decreased. This suggests that the reaction takes place in two steps (equilibrium and decomposition steps). The thermodynamic parameters determined are: enthalpy, ∆H* 151.14 kJmol-1; entropy of activation, ∆S* 275.359 Jmol-1k-1; Gibb’s free energy of activation, ∆G* -752.21 kJmol-1 and Equilibrium constant Keq, 1.33 respectively. The results show that the enthalpy value is positive indicating that the fermentation process is endothermic while the activation energy is same as the enthalpy. The entropy value is positive corroborating the positive enthalpy value. The fermentation process is spontaneous as shown by the negative change in free energy. These values were subsequently used to obtain by calculation Arrhenius constant A, 1.51x1023; orientation factor P, 1.41x10-34 and the collision frequency, Z, 1.07x1011 respectively. The calculated A and the P values obtained on the basis of collision theory and absolute reaction rate theory (or transition state theory), respectively show that the collision factor is of the order of 1011 min-1, about half that of gaseous molecules that can only be attained by an induced reduction in activation energy by a catalyst. The equilibrium constant value K suggests that the intermediate complex is rather interacting more with the substrate and also showing that only a limited amount of the substrate is converted to product. The equilibrium constant K is observed to be 1.33dm3mol-1 and not significantly far from unity implying that G* can be conveniently equated with the change in free energy at standard conditions. Finally, the type of inhibition was found to be uncompetitive from the extrapolated Lineweaver-Burk plots and did not bring about marked decrease in the rate of fermentation as expected.

El presente trabajo de investigación tuvo como objetivo evaluar de qué manera influye la sustitución porcentual del cemento por ceniza de cáscara de arroz en las propiedades físico-mecánicas del concreto, específicamente en un concreto con resistencia característica f’c= 210 kg/cm2. Este estudio se realizó utilizando agregados provenientes de la cantera "La Poderosa", ubicada en el departamento de Arequipa. La sustitución del cemento se realizó en porcentajes de 5%, 10%, 15% y 20% por ceniza de cáscara de arroz. La metodología empleada es de investigación aplicada con nivel explicativo, enfoque cuantitativo y diseño experimental puro. La población de estudio consistió en 45 probetas cilíndricas y 45 probetas rectangulares, totalizando 90 probetas de concreto. La técnica de observación fue utilizada junto con la ficha de recolección de datos del laboratorio como instrumento. Los resultados indican que el reemplazo de ceniza de cáscara de arroz en porcentajes 5%, 10%, 15% y 20%, no afecta las propiedades físico-mecánicas del concreto. Se observó que con un porcentaje de sustitución del 5%, se obtuvo la resistencia a la compresión más cercana al concreto convencional.
Crisis económica post pandemia: como afecta en el acceso a la educación superior en el Paraguay. caso: universidades públicas de Ayolas

La crisis económica post pandemia desencadenó una de las mayores catástrofes a nivel mundial, cuyas consecuencias fueron perdidas inmensas para todo el sector del mundo y muy especialmente para países en vías de desarrollo. La crisis económica también ha repercutido directamente en la educación superior. Ante la ola de despidos ocurridos durante la pandemia, la falta de acceso a un trabajo digno y la poca inversión en becas, ha obligado a jóvenes estudiantes abandonar las carreras universitarias, obligándose a buscar ingreso para tratar de sobrevivir el día a día. Esto produce consecuencias calamitosas a largo plazo, que les obliga a ingresar a la lista de estudiantes que abandonan la carrera.  Si bien las Instituciones de Educación Superior Publicas gozan de la gratuidad (Ley N° 6628 establece la gratuidad de los cursos de admisión y de grado en todas las Universidades Públicas del País), aun así, la permanencia de los estudiantes se vuelve insostenible. Además, la falta de alumnos a consecuencias de la crisis económica ha provocado el cierre de algunas carreras de las universidades públicas asentadas en la ciudad de Ayolas, cuyas consecuencias a largo plazo recaerán en las generaciones futuras que no podrán acceder a la educación superior.

Durante la pandemia del SARS-CoV-2, comúnmente conocida como COVID-19, surgieron diversas dificultades y problemáticas que se observaron de manera constante durante el período de confinamiento. Uno de los principales inconvenientes fue la excesiva prolongación de los tiempos de espera en las diferentes áreas con entradas definidas, lo cual generaba congestión y largas colas de espera para ingresar a los establecimientos debido a la sanitización de vehículos, personas u objetos. El objetivo de este estudio se centra en la reducción de los extensos tiempos de espera de sanitización en los establecimientos con entradas definidas. Para abordar este objetivo, se plantea la siguiente pregunta de investigación: ¿Cómo podemos disminuir los tiempos de espera de sanitización en los establecimientos con entradas definidas? La solución a esta problemática conlleva el desarrollo de un producto tecnológico innovador En respuesta a la pregunta de investigación planteada, se propone la construcción de un sistema embebido como método de sanitización. Este sistema tiene como finalidad reducir los tiempos de espera de sanitización en los establecimientos con entradas definidas. El Sistema Embebido Sanitizante (SES) es un dispositivo hardware diseñado y construido con componentes electrónicos, acompañado del desarrollo de un software (WebService) que registra las características esenciales para el mantenimiento y uso del sistema de sanitización.

Cloud environments can store data for the medical field with a large-scale system. Importantly, early detection of diseases using clinical data analysis is essential in medicine. Cardiovascular disease has emerged as the primary cause of sudden high-risk health-related fatalities in recent years. Analyzing time series data has become more complex and non-linear, making predictive risk analysis through feature analysis a crucial aspect of data analysis. Feature measures that are not feasible can hurt prediction accuracy and may result in misclassification. To overcome this problem, an improved clinical data analysis model using Adaptive Deep Feature Neural Classification (DFNC) method for cardiac data prediction can identify early risk stages. Time series data can be standardized from the CVD-DS dataset initially selected using a preprocessing model. Correlation with a subset of margins can be obtained using the Cardiac Deficiency Prediction Rate (CDPR). Then, the Support Frequent Scaling Feature Selection (SFSFS) model can extract the feature components based on the CDPR weights. The required features can be obtained using a deep neural classifier based on logistic neurons. The classifier is based on a Recurrent Neural Network (RNN) that deliberates each class category's feature values and Cardia Influence Rate (CIR). Classification, precision and recall can be implemented in the proposed method to provide high prediction accuracy. Additionally, early cardiovascular disease risk prediction accuracy may support early diagnosis management.

The necessity to investigate viable spectrum areas for satisfying the anticipated needs has been prompted by the rising cellular data traffic demands. As a result, the scientific community has given (mmWave) communication a lot of attention. In (5G) wireless networks, massive (mmWave MIMO) communications are often accomplished using hybrid transceivers that combine lower and higher as a digital and analog processing units phase shifters and power amplifiers respectfully. This hybrid beamforming (HB) architecture lowers costs and power use, which is consistent with the (5G) network's objective for (EE) of design. In this work, using system models of hybrid transceiver architectures, both digital (DB) and analog (AB) beamforming arrays with possibilities for antenna design, and hybrid beamforming (HB) in heterogeneous wireless networks, they trace the development of (HB) for massive MIMO connections. Authors widen in discussion by focusing on hybrid beamforming to solve resource management issue and examine the applicability of hybrid beamforming (HB) techniques while also highlighting the fascinating difficulties that lie ahead for this field. The main aim of this work is to analyse the many studies and show the advantages and weak points of each single study based on the general and famous parameters as well as explaining the efficiency of all studies. We got an overview of the hybrid beamforming, which covers topics such as application areas; In order to reduce upfront costs and continuing operating costs, the fully-connected architecture can achieve full beamforming gain per RF chain, but at the expense of increased hardware complexity. On the other hand, the low-complexity sub-connected architecture offers reduced beamforming gain.
