O atual cenário hídrico do país restringe o uso dos recursos hídricos disponíveis para fins de irrigação, visando atender o abastecimento público, por isso, objetivou-se avaliar o efeito do déficit hídrico nas variáveis de crescimento e produção do feijoeiro comum cultivado em solo de textura média e argilosa. Foram desenvolvidos dois experimentos no esquema fatorial 2 x 4, sendo a tensão para determinação da capacidade de campo em dois níveis e déficit hídrico no solo em quatro níveis, em um delineamento inteiramente casualizado, com três repetições para cada solo. A análise de crescimento foi realizada na fase de enchimento de grãos do feijoeiro e os dados foram submetidos à análise de variância (p ≤ 0,05). Quando significativos os resultados, o teste F (p ≤ 0,05) foi utilizado para o fator tensão e a análise de regressão para o fator déficit hídrico. Na fase de enchimento de grãos do feijoeiro comum, os níveis de déficit hídrico no solo de 40 e 60% da água disponível exercem efeitos negativos sobre as variáveis de crescimento e produção da cultura cultivada em solos de textura média e argilosa, independente da tensão adotada na determinação da capacidade de campo.Palavras-chave: tensão, capacidade de campo, textura, crescimento. EFFECT OF WATER DEFICIT IN THE GRAIN FILLING STAGE OF COMMON BEAN ABSTRACTThe current water scenario of the country restricts the use of available water resources for irrigation, in order to meet the public supply, therefore, it was aimed to evaluate the effect of water deficit on growth and yield variables of common bean grown on soil of medium and clayey texture. Two experiments were developed in factorial scheme of 2 x 4 with tension for the determination of field capacity on two levels and soil water deficit on four levels in a completely randomized design with three replicates for each soil. Growth analyzes were performed at the grain filling stage of the common bean and the data were submitted to an analysis of variance (p ≤ 0.05). When significant results, the F Test (p ≤ 0,05) was used for the tension factor and regression analysis for the water deficit factor. In the grain filling stage of common bean, soil water deficit levels of 40 and 60% of available water exert negative effects on the growth and yield variables of crop grown on soils of medium and clayey texture, independent of voltage adopted in determining the field capacity.Keywords: tension, field capacity, texture, growth. DOI: http://dx.doi.org/10.5935/2318-7670.v05n06a02

A matriz SWOT é uma metodologia para análise de cenários utilizada por empresas, mas ainda pouco aproveitada no setor do comércio de madeira. Este trabalho teve como objetivo descrever e analisar em uma madeireira localizada no município de Mossoró-RN, um estudo de caso da aplicação da matriz SWOT como ferramenta para planejamento estratégico. Duas estratégias de desenvolvimento foram sugeridas para o mercado de venda de madeira: a estratégia Oceano Azul e a implementação da logística reversa. Foi observada uma preferência do mercado local por apenas madeiras tropicais da espécie Manilkara sp. Dentro da filosofia do Oceano Azul, as empresas poderiam propor novas espécies de madeira de qualidade que reoriente o mercado. Outra oportunidade é a criação de convênios com o setor da construção civil, um dos principais clientes, para que seja implementado a logística reversa. A madeira descartada no final de sua vida útil poderia vir a ser coletada pelo comércio de madeira e ser convertida em bioenergia ou produtos de maior valor agregado, que poderia gerar nova fonte de renda e ajudaria no problema ambiental gerado pelo descarte irregular.Palavras-chave: planejamento setorial, tomada de decisão, vendas. WOOD MARKET: CASE STUDY ABOUT SWOT ANALYSIS AND STRATEGY FORMULATION ABSTRACT:SWOT matrix is a methodology for sceneries analysis used by companies, however it has not been fully tapped by the wood trade market. The aim of this work was to describe and analyze a study case of SWOT matrix application, as strategic planning tool in a wood trade business located at Mossoró municipality, RN, Brazil. Two strategies were suggested for the development of the wood trade market: Blue Ocean strategy and reverse logistic implementation. It was observed that the local market shows preference for the use of topical wood originated from just one species Manilkara sp. Within the Blue Ocean philosophy, the businesses could propose new species with quality wood that reorient the market. Other opportunity is establish partnerships with the construction sector, one of the main clients, to implement a reverse logistic. Dumped wood after its service life could be collected by wood sellers and converted to bioenergy or higher added value products, that could be a new source of income and would help the environmental problem created by the irregular disposal.Keywords: Sectoral planning, decision making, sales. DOI: http://dx.doi.org/10.5935/2318-7670.v05nespa21

Comparative Performance of Different Convolutional Neural Network Activation Functions on Image Classification
Authors: Azhary Muhammad Zulhazmi Rafiqi , Ritahani Ismail Amelia
Published: August 2024

Activation functions are crucial in optimising Convolutional Neural Networks (CNNs) for image classification. While CNNs excel at capturing spatial hierarchies in images, the activation functions substantially impact their effectiveness. Traditional functions, such as ReLU and Sigmoid, have drawbacks, including the "dying ReLU" problem and vanishing gradients, which can inhibit learning and efficacy. The study seeks to comprehensively analyse various activation functions across different CNN architectures to determine their impact on performance. The findings suggest that Swish and Leaky ReLU outperform other functions, with Swish particularly promising in complicated networks such as ResNet. This emphasises the relevance of activation function selection in improving CNN performance and implies that investigating alternative functions can lead to more accurate and efficient models for image classification tasks.

Published: August 2024

In this paper, it presents a detailed analysis of the use of the parabolic solar cooker in cooking and boiling water. Three models of parabolic solar cookers were manufactured with aperture diameter (96 cm, 120 cm, and 140 cm) made using satellite dishes of the same diameters and using glossy aluminum foil as a reflector sun ray after being cut into strips 10 cm wide and glued to the inner surface of the dish. A metal tin can (3L) was used as an absorbent receiver instead of a cooking pot. Experiments were conducted to boil water from the roof of the house in Nasiriyah City located in southern Iraq. Through this study, the optical efficiency of the three types of parabolic solar cookers with diameters (96,120, and 140 cm) was calculated, as they were (69,66%), (66.5, 66.35%), and (67.4,66.7%) respectively. The amount of heat gained for the three cookers, respectively (670.665, 556.394W), (1142.6, 1074.83 Watt), and (1535.38, 1460 Watt). The heat loss from the receiver, respectively (68.6, 70.53 W), (118.16, 140.385 W), and (112.69, 96.576 W). The collector efficiency of the three cookers (58.77, 53.32%), (56.16, 53.3%), and (60, 60%), and the cooking power of these cookers (475,875, 264.375 W), (413.8, 434.13 W). ), (740.25, 691.44 W). Many tests were conducted on the specified location at the weather in Iraq during the winter season. The results of the experiments showed that the parameters of the solar cooker mentioned above mainly depend on the diameter of the concentrator dish, the quality of the reflector used, the cooking time, and the closing to midday. While the high ambient air speed leads to a decrease in the pot temperature by increasing the heat loses to the surrounding air through convection, thus greatly affected the solar cooker parameters, especially the collector efficiency and cooking power, as well as the accuracy of directing the dish towards the sun, and determining the focus accurately affected on the parameters of the solar cooker too

A New Technique for PAPR Reduction in OFDM System
Authors: K. Abed Ahmed
Published: August 2024

Orthogonal frequency division multiplexing (OFDM) is an attractive technique for modern wireless communication. One major drawback of orthogonal frequency division multiplexing schemes is the high peak to average power ratio (PAPR) of the output signal. Selecting mapping (SLM) and partial transmit sequences (PTS) are two important techniques for reducing PAPR, but they need to transmit side information to indicate how the transmitter generates the signals. In this paper, we proposed an efficient technique to reduce PAPR in OFDM system. For this technique, circular shifter used to produce K cyclic sequences from the same information sequence. These sequences XOR with K randomly generated keys, the same keys used in receiver side to detect data. The sequence with the lowest PAPR among K sequences is chosen for transmission. Side Information (SI) is coded using Hamming code and embedded into the information sequence. Computer simulation tests have been applied on BPSK and N= 64 subcarriers OFDM system with the proposed method. Moreover, this system will be evaluated under the effect of AWGN channel. The results exhibit the ability of such technique to reduce the PAPR without major effect on the system performance as compared with the conventional OFDM technique. The PAPR of OFDM signal is further reduced by 4–5 dB by this technique.

Authors: I.J. Al-rubaiey Sami
Published: August 2024

New method for inhibition CO2 corrosion in Iraqi oilfield was used in this work. This new method included using combination of heat treatment of steel and added Aromatic(Tetrahydronaphthalene) compounds as corrosion inhibitor in different concentration (0.05%,0.1%, 0.2%, 0.5% and 1%). The results referred that the weight loss was reduced as inhibitor concentration increased for all conditions of specimens whether, there were heat treated or not. The combination of annealing heat treatment of samples and using Aromatic compounds inhibitor offered a better corrosion resistance than the combination of quenching + tempering(Q+T) samples. The presence of inhibitor improves the corrosion resistance for annealed samples. For fully annealing, the weight loss was 5 times lesser than that for (Q+T) samples,while the weight loss of steel (as received condition) was 3 times lesser than that for (Q+T)samples.

Published: August 2024

This study investigates the effect of thermal residual stress analysis on tetrahedral elements surface structure using finite element technique. An understanding of the effects related to the thermal residual stress is necessary to improve the ability of designers to precisely predict the catastrophic behavior of the apparatuses during overhaul. Tetrahedral elements surface structure production component subjected to applied loads needs to optimize this component that is critical to the tetrahedral elements surface structure efficiency. The applied loads and resulting residual stresses under service conditions is demanded. The finite element modeling was performed. In addition, the fracture life prediction was carried out using finite element based on fatigue analysis. It was observed that the fracture was significantly influenced due to the residual stresses. The obtained result indicates that the existence residual stresses produce the shortest fatigue life for applied loads conditions. The process is one of the promising surface treatments to increase the fracture life for tetrahedral elements surface structure.

OBJECTIVE

The purpose of this study was to conduct a literature review on transition programs from pediatric to adult care and the role of neurosurgery as individuals with spina bifida (SB) transition, and to provide a framework for neurosurgical providers to assist in the transition to adult-centered care.

METHODS

A comprehensive literature review was conducted according to the PRISMA statement, with a search in Medline and Embase to identify US clinical programs reporting on their experiences establishing a transition program for adolescents and young adults with SB. Data were collected for authors, year, transition clinic location, model of care for transition clinic, ages served, and specialty clinical team.

RESULTS

The literature search yielded 698 articles, 5 of which met the inclusion criteria. These 5 studies included 4 transition programs for which models of care and approach to transition, clinical services involved, establishment of goals, and age of initiation and transition were identified. All programs described setting transition goals, ranging from community services, to self-management, to health care navigation, to patient-driven goals, with 1 program reporting a quality-of-life measurement component to their model.

CONCLUSIONS

Robust SB transition programs can be established by applying the expanded chronic care model, reviewing lessons learned by other programs, advocating at the institutional level, and seeking support via professional organizations. While the comprehensive role of neurosurgical providers in these programs is still being defined, a shared vision of enhancing the health and quality of life for individuals with SB and their families is needed by all subspecialists involved.
Spina bifida transition care in India: strengths amidst challenges

Published: August 2024

In India, adult neurosurgeons are required to care for children regularly because the concept of dedicated pediatric specialty care is not yet entirely established in the subcontinent. Likewise, pediatric neurosurgeons do not exclusively offer their services to the young, but they also provide care to adult patients with neurosurgical disorders. This creates a medical system where the transition between specialties is not often a formal and recognized aspect of neurosurgical care because most neurosurgeons provide care for patients of all ages. Additionally, there are very few teams geared toward caring for conditions in children that merit lifelong medical support, with spina bifida (SB) being one of them. Since there are no focused or structured pediatric programs on a large scale, developing a multidisciplinary clinic for adults becomes challenging. A pragmatic approach using technology-based education, supported by an organized system or a coordinator, may be a new strategy. A new system utilizing telemedicine and smartphones for established patients maybe an alternative option for SB children in India. During virtual video conferences, an established patient may benefit from multispecialty care and education toward a smooth transition that avoids significant issues with time, transportation, or financial constraints. Achieving a seamless transition among allied specialists from the pediatric to adult systems is a utopia. The current system in the subcontinent may be improved, with an opportunity to develop smooth transition care between coordinated specialists (who simultaneously treat children and adults). Learning from various global SB management styles, the Indian transition situation may offer another model in the near future.

The characteristic features of the auditory neurons responses in terrestrial vertebrates to species-specific communication calls (analytical review)
Authors: Bibikov N. G.
Published: August 2024

One of the main functions of sensory systems is the implementation of intraspecific communication, which often occurs through the exchange of communication calls. It is quite natural that the hypothesis arises that the radiation and reception of these signals should be coordinated. There is usually a certain similarity in the characteristics of specific communication sounds and the receiving devices of an auditory analyzer. However, the degree of such correspondence in the neural structures of the brain remains a subject of debate. The review examines studies aimed at solving the issue of specialized encoding of such signals in the brains of various terrestrial vertebrates, ranging from tailless amphibians to primates. For decades, researchers have been searching for neurons in the direct auditory pathway that could serve as detectors of communication signals. However, an analysis of the extensive literature does not reveal the existence of any clearly defined area of the direct auditory pathway that would be specialized for analyzing this category of sounds. It seems that the functional significance of the neurons of this pathway consists of highlighting many features of the temporal flow within the entire perceived spectral composition of sound. This process is carried out on the trained synaptic connections in the process of permanent evolution, determined by the sensory environment. Dynamically organized ensembles of neurons can be formed in the central parts of the direct auditory pathway, synchronously reacting to the action of a certain sound. It is precisely such ensembles that can be considered as output structures of an auditory analyzer, which can determine the perception and the corresponding motor reactions.

Published: August 2024

The manuscript is an attempt to consider all methods which are applicable to investigation a directional index for composition of an analytic function in some domain and an entire function. The approaches are applied to find sufficient conditions of the $L$-index boundedness in a direction $\mathbf{b}\in\mathbb{C}^n\setminus\{\mathbf{0}\}$, where the continuous function $L$ satisfies some growth condition and the condition of positivity in the unit polydisc. The investigation is based on a counterpart of the Hayman Theorem for the class of analytic functions in the polydisc and a counterpart of logarithmic criterion describing local conduct of logarithmic derivative modulus outside some neighborhoods of zeros. The established results are new advances for the functions analytic in the polydisc and in multidimensional value distribution theory.

Published: August 2024

An electric utility's main goal is to fulfil the requirements and expectations of its customers by providing power. When there are uncertainties, like equipment failures, system reliability evaluation offers a framework to guarantee that the system will still function properly. A modified Jellyfish Search Algorithm (JFSA) has been proposed for estimation of Electric power generation system reliability indices. Particle Swarm Optimization (PSO), Genetic Algorithm (GA), and other modified versions of algorithms have been used in algorithms that use optimization methods for the assessment of reliability indices. Jelly Fish Search Algorithm has been used in power systems to find the economic load dispatch of generating units, for integration of Distributed Generation (DG) units, Maximum Power tracking of PV system and Optimal Power Flow solutions etc. However, JFSA has not been implemented for the evaluation of reliability indices for electric power generation system. In this context a modified JFSA algorithm is developed for evaluation of certain reliability indices such as Loss of Load Expectation (LOLE), and Expected Demand Not Supplied (EDNS), Loss of Load Probability (LOLP). The algorithm presented is implemented on two test system which are RBTS 6 bus system and IEEE 24 bus Reliability Test System. The Results obtained are compared for different models of Generation and Load and are analysed.
Jakub Eberle, Jan Daniel: Politics of Hybrid Warfare: The Remaking of Security in Czechia after 2014 Cham: Palgrave Macmillan, 2023, 229 pages, 978-3-031-32702-5.

Chiara Libiseller reviews Jakub Eberle and Jan Daniel’s timely book on the politics of Hybrid Warfare (HW) in Czechia. According to Libiseller, the book provides an insightful analysis of the detrimental effects of the HW discourse on democratic politics in Czechia. Leveraging a number of critical traditions, the book deepens the critique of the HW concept, which hitherto was often limited to aspects of conceptual clarity or newness. Yet, the authors' engagement with the power of the concept could have gone even further: by examining these trends as unique to Czechia and as unique to the HW discourse, the authors remain unable to address the HW discourse's international dimensions and its feeding on other militarizing discourses. Libiseller concludes that Eberle and Daniel’s book remains a powerful call to move away from Russia-centered narratives and reclaim agency to improve democratic and societal strength.

Pembelajaran Al-Quran di usia dini merupakan langkah untuk mengenalkan Al-Quran pada generasi muda. Salah satu pembelajaran Al-Quran adalah mengajarkan cara membaca Al-Quran dengan baik dan benar. Untuk itu, seorang telah dikatakan baik dan benar pada bacaannya ditentukan berdasarkan nilai dari kriteria-kriteria dalam membaca Al-Quran. Dari hasil penilaian tersebut, peringkat kemahiran seseorang dalam membaca Al-Quran bisa diperoleh. Metode penilaian yang dilakukan saat ini yang dilakukan di SD Muhammadiyah 1 Jember adalah penjumlahan nilai dari seluruh kriteria sehingga banyaknya jumlah nilai sama yang menyebabkan kesulitan dalam penentuan peringkat. Untuk itu, metode lain diperlukan agar lebih memudahkan penentuan peringkat. Salah satu metode untuk menentukan peringkat adalah metode Multi Attributive Border Approximation Area Comparison (MABAC). Metode ini menggunakan jarak kriteria pada setiap alternatif dengan mengamati jarak tersebut dari batas perkiraan area. Penentuan peringkat didapatkan dengan melakukan penghitungan normalisasi kriteria terhadap bobot alternatif yang telah ditentukan.

Relevance. The use of biologically active feed additives that support the development of normal intestinal microflora and aimed at stimulating the body’s defenses is considered by modern immunology as one of the most promising approaches to solving the problem of resisting infectious processes. Therefore, research on replacing antibiotics with drugs that are safe for humans and animals, and the introduction of technologies for the production of environmentally friendly products are a priority. One of the alternative solutions to this problem may be the use of metaprobiotics and phytobiotics. Methods. 3 groups of broiler chickens were formed: the first — OR + “Probiotsid©-Fito” (“Biotrof” LLC, Russia) at a dosage of 1 kg per 1 ton of feed, the second — OR+ “Probiotsid©-Ultra” (LLC “Biotrof”, Russia) at a dosage of 1 kg per 1 ton of feed, the third is control. Maternal and post-vaccination humoral immunity to IBD, IBD and NB were assessed using test systems ID Screen® IBD Indirect, ID Screen® Infectious Bronchitis Indirect 2.0 (“ID.vet”, France), provided by “Vet Faktor” LLC and a kit for detecting antibodies to NB virus in the hemagglutination inhibition reaction (HI) (FSBI “ARRIAH”, Russia). During the experiment, live weight, the amount of feed consumed were taken into account daily, and production indicators (feed conversion and European productivity index) were calculated according to the Ross 308 broiler breeding guide. Results. In our study, both drugs had a positive effect on the immunity and zootechnical parameters of broiler chickens. When these drugs are introduced into the diet, the live weight of broiler chickens, the average daily increase in live weight, the safety of livestock increases and the feed conversion decreases. Based on the results of a serological study, the immunotropic effect of drugs based on metaprobiotics and phytobiotics was revealed.

Published: August 2024

The application of nanotechnology is becoming increasingly prevalent in the field of dentistry. Specifically, in root canal treatment, the expulsion of microbes remains a challenge often leading to failure of the procedure. The use of sealer is an effective method to dispose of microbes, but the structure of root canal which features dentinal tubules ranging from micro to nano size underscores the need for nanoparticle sealer. Therefore, this review aimed to evaluate the implementation of nanomaterials as root canal sealer. The results showed that nanoparticle sealer increased the apical sealing ability of root canal obturation material. The concept of using nanoparticles in endodontics as a new treatment efficacy against the hidden microbes in dentinal tubules appeared to be a promising approach. The development of nanotechnology could be used to improve the ability of sealer to penetrate dentinal tubules to achieve successful root canal treatment.
