With global climate change including unpredictable geographic and temporal
weather patterns that lead to significant genotype ? environment interaction
(GEI) the maize performance assessment would need to be complemented with
stability analysis. The objectives of this study were: i) estimation of
parametric and non-parametric stability indices for grain yield of late
maturity maize hybrids, ii) assessing correlations and grouping of stability
indices for grain yield of late maturity maize hybrids. The eight maize
hybrids of FAO 700 maturity group (ZP1-ZP7, and check Ch) were evaluated for
grain yield in the multi-environment trial including five locations in
Serbia during 2020. and 2021. year. Stability analyses included twenty
parametric and non-parametric indices, Principal Component Analysis (PCA)
and Pearson?s correlations between stability indices. The sum of ranks for
tested late maturity maize hybrids were in the interval from 37 (ZP6) to 146
(ZP4). The average rank was in the range from 1.8 (ZP6) to 7.3 (ZP4). The
interval of variation for standard deviation of average ranks for tested
maize hybrids was from 1.3 (ZP4, Ch) to 2 (ZP2) indicating satisfying
accordance of utilized parametric and non-parametric stability measures. The
highest average grain yield across all tested environments was observed for
ZP1, which was second most stable hybrid. The most stable late maturity
maize hybrid tested over ten environments was proven to be ZP6 with sum of
ranks and average rank of 37 and 1.8, respectively, with standard deviation
of average rank 1.5. PCA biplot showed two groups of parametric and
non-parametric stability estimates: I group-coefficient of variation (CVi),
Eberhart and Russel?s regression coefficient (bi), Perkins and Jinks?s
regression coefficient (Bi), GEI variance component (?(i)), coefficient of
determination (Ri2); II group-Eberhart and Russel?s deviation from regression (S2di)

For many years, the increase in computing power of modern devices is achieved not
by increasing the clock frequency and bandwidth of CPUs, but by using hyper-threaded and
multicore architectures. This simple change in approach to the CPU design led to
dramatic changes in the organization of computing and became a turning point for
software developers. Software that is going to take advantage of the increased computing
power of multi-core architectures must be designed to be able to perform multiple tasks
simultaneously. When covering the topic of parallel/simultaneous computing, scientists
and IT professionals use two terms: (1) parallelism and (2) concurrency. A third
important term when considering parallel/simultaneous computing is “multithreading”. In
C++, the two most common ways to implement parallelism are concurrency and parallelism
itself. Although they can be used in other programming languages, C++ stands out for its
ability to use concurrent computations with lower-than-average utilization of general
machine resources, as well as its ability to execute complex instructions. The C++11
standard introduced support for multi-threaded programs. The C++ standard recognized the
existence of multithreading in the language and provided components for writing
multithreaded programs in the  library. This made it possible to write
multithreaded programs in C++ without relying on platform-specific extensions and
enabled the creation of portable multithreaded code with guaranteed behavior. The
 library provides extensive opportunities for organizing parallel and
concurrent calculations, it also contains the C++ memory model, conditional variables,
mutexes, etc. for thread synchronization. The article analyzes the possibilities of
writing programs in the C++ using multiple threads for parallel and concurrent execution
of tasks. It also considers the features of the C++ and the tools of the
library that make parallelism and concurrency possible.

In this work, the main emphasis is placed on the creation of a cellular automaton
model for simulating the drying process of capillary-porous materials. The possibility
of creating a cell-automatic field for the studied 3D model of a periodic drying chamber
is considered. Appropriate algorithms are developed and their software implementation is
carried out, since the cellular automata field is one of the key requirements for using
the cellular automata method. Another key requirement is the availability of adequate
transition rules. For their development, the analysis of mathematical models of heat and
moisture transfer processes in periodic drying chambers is carried out. Transition rules
are being developed, which make it possible to determine changes in temperature and
moisture content of the material, as well as changes in the main parameters of the
drying agent, which include temperature and relative humidity. The paper also simulates
the drying process of capillary-porous materials based on the developed cellular
automaton model, which includes the cellular automaton field and transition rules. The
input data for modeling are taken from the parameters of technological conditions that
are used in real drying chambers. Pine with a thickness of 45 mm was chosen as the
studied capillary-porous material. with an initial moisture content of 65%. As a result
of the simulation, graphical dependences of the desired parameters of the material and
the drying agent with respect to time were obtained. Verification of the obtained
results is carried out by comparing them with data collected by sensors in a real drying
chamber. For comparison, a relative error is determined, the average values of which do
not exceed 10%. This result confirms the adequacy of the developed model of cellular
automata.

Authors: Ridyanto Muhammad , Sukarno Subiakto
Published: December 2023

PT Kaltim Daya Mandiri is a utility provider company located in Bontang, East Kalimantan, Indonesia, currently planning to invest in a new project investment by constructing a nitrogen plant in Bontang and a utility center plant in West Papua to support the business expansion of PT Pupuk Kalimantan Timur in the eastern region of Indonesia. To execute the project, the company must ensure the adequacy of cash flow to support the existing operational and project activities needs; therefore, it requires cash flow management and the right financing strategy to ensure the company’s financial performance remains stable.
In this study, the analytical method used to generate a strategic formulation to optimize financial performance during projects is using quantitative and qualitative analysis. The strategic formulation comprises a financial strategy, specifically the option of project financing and a tax planning strategy related to tax refund and tax exemption. From the exploration of several strategies, there are two options for a combination of strategies, namely Scheme 1: Tax planning strategies and financial strategies through utilizing banking products (investment loan and short-term loan) and Scheme 2: Tax planning strategies and financial strategies through utilizing debt securities (corporate bonds and medium-term note).
The simulation shows that in terms of the efficiency aspect towards interest cost imposed during the period, impact on the company’s cash flow during the project development period, and the proforma of financial performance, Scheme 1 is more favorable compared to Scheme 2. Using Scheme 1, the bank loan’s interest will be imposed on the cash flow statement and profit and loss statement after the project is declared commercial. During the project construction, the company will only be exposed to an interest construction, which will be an additional loan balance after the project commercial. In addition, instalment payments (principal and interest portion) have an impact on reducing the loan balance, and the future interest expense will decrease. Whereas, by using Scheme 2, the company will be directly burdened by interest coupons that need to be paid quarterly and constantly, which can affect cash flow and profit and loss statements directly.

Los peces serránidos se distribuyen alrededor del mundo en aguas tropicales y templado cálidas y constituyen algunas de las especies arrecifales con mayor importancia comercial. Las 10 especies de peces serránidos del género Paralabrax Girard, 1856, están confinados a las costas de América, localizándose principalmente en el océano Pacífico, incluido el Golfo de California  presentándose cinco de ellas en ambos litorales de la península de Baja California, México. Se obtuvo un total de 278 peces de tres especies de Cabrillas del género Paralabrax [P. auroguttatus Walford, 193; P. clathratus (Girard, 1856) y P. nebulifer (Girard, 1856)], procedentes de varias localidades del Golfo de California y del océano Pacífico y resultaron parasitados en los dientes faríngeos de la placa inferior y branquias con una especie de monogéneo de la familia Capsalidae. La característica del opistohaptor aseptado es compartida con los géneros de cuatro subfamilias: Entobdellinae, Nitzschiinae, Benedeniinae y Encotyllabinae. Difieren de los cinco géneros de la subfamilia Entobdellinae por no poseer un prohaptor formado por dos áreas glandulares alargadas, ligeramente deprimidas. Difieren del único género de Nitzschiinae por no tener prohaptor en forma de botrios. Difieren de los 17 géneros de la subfamilia Benedeniinae porque sus representantes tienen el opistohaptor con forma circular ensanchada y por poseer vagina. Finalmente, aunque por la morfología general del cuerpo, más cilíndrica que ovoidea, los ejemplares de este trabajo muestran más semejanza con los ejemplares de los dos géneros reconocidos de la subfamilia Encotyllabinae, difieren de ellos por no tener opistohaptor con un pedúnculo muy largo y dos pares de ganchos, uno de los cuales es muy grande, ocupando gran parte del área del mismo, así como por no presentar vagina. Por las características del opistohaptor aseptado de los monogéneos estudiados, en forma ovalada con abertura estrecha y bordeada por membrana marginal, se propone un género y especies nuevos, como Bajacalifornia universitaria. Hasta no tener un estudio molecular que lo confirme, en este trabajo se incluyen en la subfamilia Encotyllabinae.

Published: December 2023

Engineering systems are often subject to complex loading mechanisms including accelerated mechanical shock during transportation, handling, and operations. Shock can be understood as a drastic, irregular change in acceleration experienced by an object due to impact at a very short period. This paper presents a preliminary study of the crashworthiness properties of in-service industrial marine fenders (or bumpers) intended for shock energy absorption. The peak accelerations (Gpeak) of the test specimens are experimentally measured and compared to theoretical estimations. The energy absorptions and impact forces of the test specimens are calculated using analytical formulations. The effects of introducing tubular through-holes in the specimens on the resulting peak accelerations and thereby the shock energy absorbing capacities are also investigated. Test specimens of thicknesses ranging between 10 mm and 30 mm are subjected to half-sine shock waves between 50G and 70G, which are generated by dropping a 5-kg payload from different heights ranging from 150 mm to 280 mm onto a padded shock seat for a pulse duration between 5 and 8 ms. The analytically determined Gpeak agrees well with the experimental values. It is found that the through-holes specimens with lower Gpeak, resisted smaller impact forces and absorbed up to 12% lesser energy per unit mass than their solid counterparts.

Published: December 2023

Coatings are frequently used to enhance the mechanical and physical characteristics of mild steel by protecting mild steel surfaces against corrosion. Corrosion might attack surface without proper coating method which may lead to structural failures and increase maintenance cost. The main objective of this study is to investigate the effect of CoNiFe nanocrystalline coating on surface roughness, hardness, and tensile performance of mild steel substrate. Different parameters were introduced, such as current, pH, deposition times and heat treatment to analyse surface roughness, hardness, and tensile strength of CoNiFe nanocrystalline coating. The lowest surface roughness of 2.14 µm was recorded by CoNiFe nanocrystalline coating with 30 minutes deposition time at pH 3, I: 3 A and heat treated, while the highest recorded surface roughness of 4.233 µm was detected on uncoated mild steel. The highest improvement of microhardness was observed on CoNiFe nanocrystalline coating with 45 minutes deposition time at pH 3, I: 1.5 A and heat treated (393.6 Hv) as compared to the uncoated mild steel (171.44 Hv). Tensile performance of CoNiFe nanocrystalline coating with 45 minutes deposition time at pH 3, I: 1.5 A and heat treated was the highest with yield stress and ultimate tensile stress of 472.35 MPa and 559.11 MPa, respectively. The lowest tensile performance was recorded by uncoated mild steel with yield stress and ultimate tensile stress of 149.40 MPa and 186.78 MPa, respectively.CoNiFe nanocrystalline coating has considerably improved the mild steel surface roughness, hardness and tensile strength which indicate superior mechanical properties for future engineering application.

With the growing demand to identify the best materials and parameter settings for these applications, our project focuses on creating a 3D model of tensile test specimens with varying infill densities, wall perimeters, and layer heights for both ABS and PETG materials. Our goal is to evaluate how these parameter settings affect the tensile properties of each material. We fabricated the 3D specimen model following ASTM D638-14 Type I dimensions and conducted tensile tests using a Universal Testing Machine at a 5mm/min feed rate. Our results indicate that increasing infill density enhances Young's modulus and tensile strength for both ABS and PETG materials. Young's modulus for ABS shows marginal improvement with different wall perimeters. A similar trend is observed in Young's modulus and tensile strength for ABSand PETG at different layer heights. PETG exhibits higher tensile strength, while ABS demonstrates greater stiffness.

Granite waste that increasingly accumulates yearly is significant with granite industry growth. This research aims to use nano silica extracted from granite dust to identify the effect of nano silica on the mechanical properties of Basalt and Glass Fibre Reinforced Polymer Composite. The approach encompassed three distinct weight percentages of nano silica, specifically 1 wt%, 3 wt%, and 5 wt%, seamlessly blended into a polyester resin matrix. The evaluation of composite mechanical attributes was conducted through compression and Izod impact tests by following ASTM D3410 and ASTM D256. Remarkably, the pinnacle of this enhancement materialises at the 1 wt% threshold,signifying the impact strength and compression strength values. Beyond this point, a decline was observed, underscoring the critical importance of judicious weight percentage selection. This novel composite configuration holds promising implications, particularly for components within container trucks, where the fusion of exceptional impact and compression strength is paramount.

Poverty is a serious problem faced by humanity, including in Indonesia. Poverty that is left without a solution will threaten the faith, morals, and thoughts of each individual. More than that, poverty is also very vulnerable to threatening social and national life by causing horizontal conflicts in society. The Quran as a syifa' is expected to be able to provide several solutions to alleviating existing poverty. This research aims to analyze the solutions offered by the Quran regarding poverty alleviation. This research adopts qualitative research whose data comes from the Quran. Quran verses are grouped into relevant themes. Grouping was carried out by reviewing studies by previous scholars. Research finds that empowering potential through work, creating social justice, appropriate use of resources, and distribution of wealth are the Quran's solutions to poverty. The Quran not only emphasizes the importance of each individual's hard work but at the same time also opposes the elite's monopoly on economic resources and encourages the creation of universal social justice.

The objective of this article is to examine and analyze Arthur Jeffery's thoughts on the Qoran. This research is qualitative research with a literature review. Arthur with his philological method, analyzes the foreign languages (non-Arabic) contained in the Quran, at least he found around 316-317 foreign languages adopted by the Prophet in the Quran, as stated in his book entitled “The Foreign Vocabulary of The Quran”. Various accusations directed by Arthur to discredit and weaken the religion of Islam have raised doubts about this divine revelation. The results of this study indicate that the accusations made by Arthur about the existence of foreign words and the Prophet Muhammad who has been influenced by previous religions, such as Judaism and Christianity mostly use prejudice and mere assumptions and do not present scientific analysis data with evidence of historical studies and data as reinforcement for his argument.

Currently, the inter-religious tolerance movement is being called upon, considering the many religious conflicts that have occurred in Indonesia. Tolerance is a form of respect and not imposing will on others. However, currently, there are still many cases of insulting other religions, both in terms of offerings or ways of worship. This happens because there is still fanaticism and radicalism which considers the teachings of one's own religion to be the most correct, considering the teachings of other religions to be heretical or infidel because they are different from their religion. This study aims to explain how ethics communicates with other religions. Literature research is used as a method in this study, namely by collecting and analyzing the interpretations of the verses used. The results of this study are QS. al-An'am (6): 108 gives advice to Muslims not to insult God and the teachings of other religions even though they are emotional or feel disturbed. Not only in cases of idols but also in other religions. On the other hand, Muslims must communicate in a polite and gentle way so that sympathy from other religions arises and good relations are established.

The aim of this study is to examine the attitudes of graduate and doctoral students towards postgraduate education in terms of various variables. For this purpose, the research was designed in the survey model. The participants of the research are 663 students who are continuing their postgraduate education at a university. The data were collected with the “Attitude towards Postgraduate Education Scale” developed by Çetin et al. (2023). In the analysis of the data, Kruskal-Wallis H test and Mann-Whitney U test, which are non-parametric tests, were used according to the structure of the variables in the data set. As a result of the Kruskal-Wallis H test and the Mann-Whitney U test, the effect sizes of the variables with significant differences between them were determined and interpreted. As a result of the research, it was seen that more than half of the participants had a positive attitude towards postgraduate education. In the sub-dimensions of valuing postgraduate education and giving importance to postgraduate education, a significant difference was found in favor of female students in the scores of attitudes towards postgraduate education within the gender variable. No significant difference was observed in any of the sub-dimensions in terms of the age variable. In terms of the variable of the department where the postgraduate education is given, the attitude scores of the students studying in the education departments showed a significant difference in the first two dimensions, compared to the students of the science departments. When the students' attitude scores were analyzed according to the type of program, it was observed that there was a significant difference in favor of doctoral students in the first two dimensions.

Authors: Ikram Benheddi , Mohammed Kamel Si
Published: December 2023

While the COVID-19 pandemic has triggered the likelihood and intensity of the increased budget deficit affecting the inflation rate, increasing concerns emerge regarding the ability of governments to stabilize the price under the fiscal dominance in oil-exporting countries. This paper examines the viability of a non-Ricardian regime in Algeria under COVID-19 and the consequences of fiscal dominance on monetary policy. The study demonstrated that budget deficit/GDP, official exchange rate, an interest rate of treasury bills, oil prices, and broad money/GDP are all significantly connected to the inflation rate using an ARDL model from 1998 to 2020. Long-term cointegration is present, supporting the legitimacy of the non-Ricardian regime and the importance of fiscal policy. Empirical findings show the substantial role of the budget deficit, particularly during the COVID-19 period, on Algerian inflation, which has implications for the central bank, government.

Authors: Damián-Huato Miguel Ángel
Published: December 2023

Objetivos: evaluar la aplicación de tecnologías radicales y progresivas en el manejo de maíz de secano en dos municipios de Puebla-México; identificar las tecnologías aplicadas por los maiceros eficientes y reflexionar sobre su impacto en la productividad y en la relación campesino-tierra. Metodología: se aplicaron 60 encuestas en Cohetzala y 118 en Chalchicomula de Sesma, para medir la apropiación de tecnologías radicales (IATR) y progresivas (GETP). Se diseñaron dos tipologías de productores. Resultados: se encontró que el IATR fue bajo en Cohetzala y medio en CHS, sin mostrar una relación con los rendimientos. Respecto al GETP, ambos municipios mostraron valores altos y hubo una relación directa con los rendimientos. La tipología de maiceros según su productividad reveló que la integración de tecnologías distintas en el manejo de maíz derivó en una innovación que mejoró los rendimientos y la sostenibilidad; la mayoría de los maiceros aplicaron un diálogo de saberes que tiene como base el manejo de la biodiversidad, la cual genera colaboraciones y simbiosis. Limitaciones: no se midió a nivel de campo la diversidad de flora y fauna que cohabita en la milpa, ni se realizaron estudios de laboratorio para analizar los atributos de los suelos. Conclusiones: garantizar el derecho a la alimentación exige la identificación de milperos eficientes, la evaluación de las tecnologías que se aplicaron en la construcción del agronicho y la revaloración del diálogo de saberes.
