Flock Uniformity – A New Poultry Welfare Indicator?
Authors: Vieira-Pinto Madalena
Published: October 2023

Directive 2007/43/CE establishes the system for assessing the welfare of poultry at the slaughterhouse level, which consists of a systematic assessment of indicators by the slaughterhouse's official veterinarian (OV). In Portugal those indicators include mortality rate on the farm and during transport to the slaughterhouse, as well as post mortem findings such as footpad dermatitis (FPD). Nevertheless, the increasing importance of this topic leads to a dynamic search for novel welfare indicators such as flock uniformity. Reduced animal welfare can be indicated by poor flock uniformity due to either general housing or management problems, or bird health problems. For that reason, the aim of this study was to investigate the usefulness of the parameter “flock uniformity “(FU) as an indicator of animal welfare to be used during slaughter of commercial broiler flocks. For that, a total of 26 randomly selected mixed-sex Ross 308 broiler flocks were studied. All batches were raised under similar farm management systems with a medium age of slaughter of 35 days. To study the uniformity, 10% of each batch was observed and categorized after stunning at the slaughterhouse, using the following scores based on % of small animals observed: score 1 ([0 -2,5%[; high uniformity); score 2 ([2,5-5%[; normal uniformity); score 3 ([5-7,5%[; bad uniformity); score 4 (≥7,5%; no uniformity). Additionally, the following percentage data were collected for each flock: mortality in transport, total condemnation (TC), the % of TC only due to disease cause and the % of TC due to errors related to slaughter process. The results showed that poorer uniformity was highly associated with increased rejection level (p= 0.002) and increased rejections caused by disease (p = 0.001). This highlights the potential use of this parameter as an animal welfare indicator and also as a criterion to be used under a risk-based meat inspection approach: The worse the FU, the more time the OV must dedicate to the post-mortem inspection of that batch.
Study on the Prevalence and Associated Risk Factors of Bovine Eimeriosis in Guangua District, Northwestern Ethiopia
Authors: Fesseha Haben
Published: October 2023

A protozoan disease called Eimeriosis, which affects cattle all over the world, is brought on by different Eimeria species. In the Guangua district of Northwest Ethiopia, this study set out to identify the Eimeria species already present and evaluate the risk factors that go along with them. A cross-sectional study with random sampling was carried out using Coprological methods from July 2019 to March 2020. In this study, the prevalence of coccidia species was 17.83% (82/460), with Eimeria bovis, Eimeria zuernii and mixed infections having a respective prevalence of 7.83%, 3.25%, and 6.74%. The severity of coccidia (Eimeria) infection was shown to be statistically significant (p 0.05) when cattle age and month of the year were taken into account. The season, sex, or breed of cattle did not, however, appear to be associated with coccidial infection in statistically significant (p > 0.05) ways. The study area had a moderate prevalence of cattle Eimeriosis. To implement strategic control and prevention measures, it is, therefore, necessary to conduct a study using molecular techniques to identify Eimeria species and to raise cattle owners' awareness of management practices.

Authors: Guyassa Chala
Published: October 2023

Background: Bacterial diseases transmitted through food pose a serious threat to human and animal health. Salmonella and S. aurous are among the major foodborne pathogens. It is becoming a worldwide problem to date. In this regard, there is a lack of information among farms in western Ethiopia. Therefore, the study was conducted to isolate, identify, and assess the antimicrobial susceptibility profile of Salmonella and S. Aureus from Selected Dairy Farms in the study area. Methodology: A cross-sectional study was done from December 2018 to June 2019 on small scale dairy farms from Bedele and Nekemte town, Western Ethiopia with the objective of isolating and identifying Salmonella and S. Aureus from lactating cows, milkers’ and milking equipment at farms and to determine the antimicrobial susceptibility of the isolates. A total of 383 samples consisting cow milk, feces, cow nasal swab, milkers’ hand swab, milkers nasal swab, bucket swab, and floor swab were collected from 20 dairy farms. The samples were examined for the presence of Salmonella and S. Aureus following standard techniques and procedures. Agar disc diffusion method was used for the antimicrobial susceptibility testing. Results: The overall occurrence of Salmonella and S. Aureus was 2.35%and 2.35% respectively. Out of the 9 Salmonella isolates, 5(4.95%), 3(2.97%), and 1(5%) were isolated from udder milk, rectal feces and floor swab respectively. S. Aureus isolate was highest in udder milk 3(2.97%), followed by cow nasal swab 2(1.98%), feces 1(0.99%), bucket swab 1(5%), floor swab 1(5%) and milker’s nasal swab 1(5%). All salmonella isolates were 100% sensitive to nalidixic acid, however 55.55%, 22.22 %, and 11.11, respectively, were resistant to cefoxitin, tetracycline, and gentamycin. The antibiotic susceptibility profiles of the S. Aureus showed that 55.55% and 11.11% were resistant to Penicillin G and Erythromycin, respectively and were 100% sensitive to cefoxitin, nitrofurantoin, and gentamicin. Conclusion: Even if the current study shows lower prevalence, lower antimicrobial resistance and higher susceptibility for most antimicrobials, stringent control measures, such as treatment of positive cases with effective medications and preventative measures including strict hygiene standards, such as cleaning of the floor, pens, and milking equipment, as well as adequate hand washing throughout the milking process, should be adopted.

Authors: Coelho da Silva Cintia
Published: October 2023

O presente artigo visa explicitar como a ficção científica arquitetou previamente (programação preditiva) aquilo que os profissionais da tecnologia criaram ou revelaram ao público, posteriormente: a ideia do androide, dos robôs e da Inteligência Artificial (IA). A Série Westworld da HBO Max retrata uma realidade em que não se pode distinguir com clareza onde está o elemento humano e o artificial. Um mundo onde seres humanos e máquinas trabalham e vivem lado a lado, sem que os humanos se deem conta disso. O ensaio foi elaborado a partir da seleção e análise de cenas, por meio do método de Análise Crítica do Discurso (ACD) de Norman Fairclough (1995), em que fica explicitada tal indistinção laboral entre homem e máquina. O resultado foi a constatação do domínio da máquina sobre a humanidade.
Palavras-chave: Inteligência Artificial, Westworld, trabalho, programação preditiva, tecnologia.

Authors: Montargil Gilmar da Silva
Published: October 2023

Lançado em setembro de 2020, o game Cyberpunk 2077 apresenta um futuro em que já não é possível desconectar a mente do ciberespaço, lembranças são guardadas em chips e a busca por peças, softwares e antivírus de melhor qualidade garantem uma vida segura e semi-eterna. Nesse sentido, o objetivo desse artigo é fazer uma leitura deleuziana da estrutura narrativa de Cyberpunk 2077, partindo da hipótese que o game alicerça o protagonista V em situações que aclaram questionamentos trazidos por Deleuze em obras como Diferença e Repetição, Mil Platôs e em entrevistas como Controle e devir. A partir do olhar deleuziano, percebe-se em Cyberpunk 2077 problematizações acerca de potenciais mecanismos de agenciamento da sociedade de controle e uma crítica a um eventual descarte do corpo pelo tecnocapitalismo de 2077 a partir de conceitos como devir, rizoma, comunicação a-paralela.

Published: October 2023

The interdisciplinary studies in the teaching of mathematics through art makes this articulation a source that generates comprehensive and significant knowledge for both areas, with the possibility of exploring playfulness and creativity for educational purposes. In this context, the string art technique (which consists of building different figures as a result of the orderly manipulation of strings on points fixed on a solid surface) is shown as a potential didactic resource for the development of methodologies that can improve aspects of teaching and learning of geometric figures and their properties, such as conical sections (little explored in relation to other geometric shapes). The exploration of the technique can help the teacher in the teaching process of Analytical Geometry, through dynamic classes using manipulative materials, with the possibility of obtaining better learning results. In this sense, the present work explores the context of interdisciplinary between Mathematics and Arts and proposes a didactic sequence directed to the teaching of conic sections in High School, with string art. The didactic sequence evidences a methodology oriented to the participation of students as active in the construction of their own knowledge, based on the guidelines for the construction of geometric figures by the mediator teacher. In the professional perspective, the objective of the didactic sequence (product of this work) is to help the teacher in the construction of new teaching methodologies that contribute to improve the student's knowledge about conics, in order to obtain satisfactory results in the teaching of Geometry and overcome difficulties observed in classroom practice.

Authors: Sultana Naznin , Zubair Ahmed
Published: October 2023

Due to their earth-abundance, direct and adjustable bandgap in the range of visible light, and lower fabrication cost on large areas, Cu2ZnSn(SxSe1-x)4 semiconductors, commonly known as kesterite, are gaining recognition as potential materials for affordable, environment‐friendly, and high‐efficiency thin‐film photovoltaics. In this work, we numerically investigated the performance parameters of a single-heterojunction solar cell using Cu2ZnSnS4 (CZTS) / Cu2ZnSnSe4 (CZTSe) absorber layer and ZnS buffer layer, with SnO2 transparent conducting oxide (TCO) under a range of operating conditions and cell parameters. Maximum efficiency of 20.68% was obtained for a 5.5 µm absorber layer with 0.01 µm ZnS buffer layer for Cu2ZnSnSe4 solar cell, and 22.86% was obtained for a 6 µm thick Cu2ZnSnS4 absorber layer with 0.03 µm ZnS layer at room temperature and standard irradiance. The increase of irradiance to thrice the standard value led to 1% and 5% increase in efficiency for CZTS and CZTSe cells, respectively. Efficiency increased by 39% and 6.6% when the front surface was textured at an angle of 90° for CZTS and CZTSe cells, respectively. The CZTS and CZTSe based solar cells with optimized thickness and 90° textured front surface with three times the standard irradiation, showed 25.59 % and 21.52 % efficiency with open circuit voltage 1045 mV and 579.4 mV and short circuit current 85.84 mA/cm2 and 140.7 mA/cm2, respectively. The proposed architecture in this study will help produce next-generation solar cells that are both economical and energy-efficient.

ABSTRACT The presence of reliable and continuous electrical energy is very important to support modern human life, therefore its necessary to build a transmission network that connect to each other between substations. One of the important components to maintain the availability of reliable electric power in addition to the electric power protection system is the grounding system at the substation. The grounding system is useful for minimizing electric power disturbances due to overvoltage originating from the operation of existing equipment in the substation system as well as due to other factors external is a lightning impulse. In this paper, we will describe how to design and install a grounding system in substations. The type of installation of the grounding system selected is the mesh or grid method. The making of this grounding system refers to the work plan and working contract conditions, formulas commonly use in electric power engineering theory, the applicable rules and regulation of electric power system.  The most important standards and variables in this design are the type and resistivity of ground resistance, step voltage, touch voltage and the length of conductor used. The result of this design after working for one month in the new substation area and measured using an Earth tester showed good result of ≤ 0.19 ohm as required by the owner is 0.3 ohm. The result of this measurement mean that the result of the grounding system design has been successfully implemented is 0.19< 0.3 ohm.

Antropoceno, desenvolvimento e (re)existências
Authors: Souza Jéser Abílio de
Published: October 2023

Este artigo tem o objetivo de explorar algumas críticas e alternativas ao desenvolvimento a partir de experiências de (re)existências que emergem de sujeitos e grupos historicamente marginalizados no sistema mundial, a fim de compreender as contra-narrativas, os contra-arquivos e os distintos pontos de partida que são oferecidos. Metodologicamente, adotou-se uma postura exploratória e descritiva que oferece um panorama amplo sobre críticas e alternativas ao desenvolvimento. Inicialmente, buscou-se problematizar as visões do desenvolvimento e as ideias sobre extrativismo e sustentabilidade, dentro de breves recortes históricos. O arcabouço teórico buscou dialogar os estudos de abordagem crítica ao desenvolvimento com os estudos decoloniais. Em seguida, discutiu-se os modos de vida alternativos ao desenvolvimento e a gestão de bens comuns enquanto formas de (re)existências de grupos marginalizados. O argumento central consiste no entendimento de que os modos de vida alternativos ao desenvolvimento são projetos decoloniais, pois constituem lutas políticas e práticas de oposição e intervenção. Tais lutas e práticas são marcadas por múltiplas e heterogêneas visões e maneiras de experienciar o tempo, o espaço e outras bases de subjetividades e sociabilidade humana.

Sugarcane (Saccharum Officiarum L.) is a plant with high economic value, especially in developing countries with tropical climates such as Indonesia, because of the high sugar content in the stems. Preparation of seeds and determination of specific location superior varieties is one of the determining factors for the success of sugarcane cultivation. This research was conducted to determine the effect of bud location from bud set and several varieties on the growth of sugarcane seedlings. The research was conducted from July to December 2022, at the Jember State Polytechnic nursery using a two-factor Randomized Group Design (RAKF). The results showed that good germination growth came from the location of the scion buds. The location of the buds has a significant effect on the parameters of the number of leaves and the number of tillers. Kinds of sugarcane varieties had a significant effect on plant height (cm), number of leaves, number of tillers. The VMC 76-16 variety was the best for the number of leaves and plant height parameters, while the GMP 04 variety was the best for the number of tillers.
