Pneumatic system or bleed air has the aim to provide information in performing troubleshoot techniques and maintenance procedures on engine bleed air system components. Engine bleed air system is a system that produces compressed air from engine rotation. This process can produce compressed air that enters the system needed by the aircraft, taking into account low pressure, overpressure and overheat. With overheat conditions in the pneumatic system on the current aircraft, the author designs a Pneumatic system simulator when overheating occurs on this aircraft using simple electronic objects and components that have functions and working principles resembling the original system. The incoming power supply provides 12 V power which is then flowed through a stepdown regulator to reduce the voltage to 5 V which is used to supply the LED lamp, pushbutton switch, temperature sensor, and Arduino. When the temperature sensor detects a temperature that exceeds the predetermined limit, the Arduino will provide input to the LED lamp to light up. Pneumatic system simulator tool when overheating occurs in engine bleed water does not work if there is one component not connected or incorrect installation and not as expected. In the initial stage of the experiment where this hot gun is an example of media when simulated, namely as a compressor to produce hot air. In the first experiment set at a temperature of 29C, the overheat indicator lamp did not turn on. And at a temperature of 30C, the overheat indicator lamp is also still not lit. At this temperature 31C, the overheat indicator lamp and also the fault indicator lamp are lit. That indicates that the temperature has touched the maximum limit or has exceeded the maximum limit.

Published: December 2023

The use of radar in aviation primarily centers around aircraft weather radar systems, which provide real-time monitoring of weather conditions surrounding the aircraft. Antennas play a crucial role in enabling detection within these radar systems. This article is dedicated to research efforts focused on developing a microstrip antenna design using array techniques to achieve high gain. The research methodology follows Thiagarajan's 4D approach, encompassing the Define, Design, Develop, and Disseminate stages. To optimize performance, the research encompasses the creation of various antenna designs, including single patches, 1x2, 4x4, and 8x4 arrays, employing feed and coaxial insert enumeration methods. Additionally, comparisons are drawn between two substrates, specifically FR-4 and Rogers RT- 5880. Parameters under scrutiny encompass gain, VSWR, return loss, bandwidth, and radiation patterns. The design process for microstrip antennas involves intricate dimensional calculations and array method selection, followed by a detailed application-based design. The results consistently demonstrate VSWR values below 2 and return loss values below -10 dB for microstrip antenna designs on both FR-4 and Rogers RT-5880 substrates. The most significant gains were achieved by an 8 x 4 array design employing the insert feed enumeration method on a Rogers RT-5880 substrate, reaching an impressive 17,979 dBi. The widest bandwidth is observed in the design of the 1x2 array using the Rogers RT-5880 substrate, reaching 651.1 MHz. Moreover, it is evident that an increase in the number of patches in the array corresponds to an increase in gain. Notably, Rogers RT-5880 material demonstrates a superior capacity to produce higher gain compared to FR-4 substrates

The navigation equipment currently in use in Indonesia for flight is DVOR. The PIR (Portable ILS/DVOR Receiver) equipment must be subject to periodic ground check procedures using to ensure that the equipment is in good working condition. The PIR currently in use is manufactured by the manufacturer of DVOR equipment. As a result, the design of a portable DVOR receiver is underway, along with the measurement and evaluation of its performance, using the RTL-SDR R820T2 device in combination with the Python programming language. This design implements the waterfall method as its technique. The output of the portable DVOR receiver that employs RTL-SDR takes the form of 30 Hz amplitude modulation percentage. The portable DVOR receiver using RTL SDR, which features a positive-intrinsicnegative (PIR) manufacturer, exhibits an average deviation of 0.25% for the 30 Hz amplitude modulation percentage. According to these findings, the design tool functions sufficiently well.
Beyond the horizon: Innovations and future directions in axial-spondyloarthritis
Authors: Venerito Vincenzo , Del Vescovo Sergio , Lopalco Giuseppe , Proft Fabian
Published: December 2023

Axial spondyloarthritis (axSpA) is a chronic inflammatory disease of the spine and sacroiliac joints. This review discusses recent advances across multiple scientific fields that promise to transform axSpA management. Traditionally, axSpA was considered an immune-mediated disease driven by human leukocyte antigen B27 (HLA-B27), interleukin (IL)-23/IL-17 signaling, biomechanics, and dysbiosis. Diagnosis relies on clinical features, laboratory tests, and imaging, particularly magnetic resonance imaging (MRI) nowadays. Management includes exercise, lifestyle changes, non-steroidal anti-inflammatory drugs and if this is not sufficient to achieve disease control also biological and targeted-synthetic disease modifying anti-rheumatic drugs. Beyond long-recognized genetic risks like HLA-B27, high-throughput sequencing has revealed intricate gene-environment interactions influencing dysbiosis, immune dysfunction, and aberrant bone remodeling. Elucidating these mechanisms promises screening approaches to enable early intervention. Advanced imaging is revolutionizing the assessment of axSpA's hallmark: sacroiliac bone-marrow edema indicating inflammation. Novel magnetic resonance imaging (MRI) techniques sensitively quantify disease activity, while machine learning automates complex analysis to improve diagnostic accuracy and monitoring. Hybrid imaging like synthetic MRI/computed tomography (CT) visualizes structural damage with new clarity. Meanwhile, microbiome analysis has uncovered gut ecosystem alterations that may initiate joint inflammation through HLA-B27 misfolding or immune subversion. Correcting dysbiosis represents an enticing treatment target. Moving forward, emerging techniques must augment patient care. Incorporating patient perspectives will be key to ensure innovations like genetics, microbiome, and imaging biomarkers translate into improved mobility, reduced pain, and increased quality of life. By integrating cutting-edge, multidisciplinary science with patients' lived experience, researchers can unlock the full potential of new technologies to deliver transformative outcomes. The future is bright for precision diagnosis, tightly controlled treatment, and even prevention of axSpA.

All You Need Is Fault: Zero-Value Attacks on AES and a New λ-Detection M&M

Published: December 2023

Deploying cryptography on embedded systems requires security against physical attacks. At CHES 2019, M&M was proposed as a combined countermeasure applying masking against SCAs and information-theoretic MAC tags against FAs. In this paper, we show that one of the protected AES implementations in the M&M paper is vulnerable to a zero-value SIFA2-like attack. A practical attack is demonstrated on an ASIC board. We propose two versions of the attack: the first follows the SIFA approach to inject faults in the last round, while the second one is an extension of SIFA and FTA but applied to the first round with chosen plaintext. The two versions work at the byte level, but the latter version considerably improves the efficiency of the attack. Moreover, we show that this zero-value SIFA2 attack is specific to the AES tower-field decomposed S-box design. Hence, such attacks are applicable to any implementation featuring this AES S-box architecture.Then, we propose a countermeasure that prevents these attacks. We extend M&M with a fine-grained detection-based feature capable of detecting the zero-value glitch attacks. In this effort, we also solve the problem of a combined attack on the ciphertext output check of M&M scheme by using Kronecker’s delta function. We deploy the countermeasure on FPGA and verify its security against both fault and side-channel analysis with practical experiments.
Low Cost and Precise Jitter Measurement Method for TRNG Entropy Assessment
Authors: Bernard Florent , Garay Arturo , Haddad Patrick , Bochard Nathalie , Fischer Viktor
Published: December 2023

Random number generators and specifically true random number generators (TRNGs) are essential in cryptography. TRNGs implemented in logic devices usually exploit the time instability of clock signals generated in freely running oscillators as source of randomness. To assess the performance and quality of oscillator-based TRNGs, accurate measurement of clock jitter originating from thermal noise is of paramount importance. We propose a novel jitter measurement method, in which the required jitter accumulation time can be reduced to around 100 reference clock periods. Reduction of the jitter accumulation time reduces the impact of the flicker noise on the measured jitter and increases the precision of the estimated contribution of thermal noise. In addition, the method can be easily embedded in logic devices. The fact that the jitter measurement can be placed in the same device as the TRNG is important since it can be used as a basis for efficient embedded statistical tests. In contrast to other methods, we propose a thorough theoretical analysis of the measurement error. This makes it possible to tune the parameters of the method to guarantee a relative error smaller than 12% even in the worst cases.

Neste artigo, analisamos o posicionamento de docentes e gestores de uma escola, obtido por entrevistas e observação em reuniões pedagógicas, sobre a implantação do Programa Mais Educação (Decreto nº 54.452/2013), da Secretaria Municipal de Educação de São Paulo. O decreto dividiu os dois ciclos de aprendizagem em três, ampliou as possibilidades de retenção e, entre outras finalidades, estabeleceu a meta de alfabetizar 100% das crianças até o 3º. ano do Ensino Fundamental. Gestoras e docentes entrevistadas avaliam o encurtamento dos ciclos como bem-vindo e, de modo conexo, são reticentes com a progressão continuada. Mesmo favoráveis à reprovação das crianças consideradas com dificuldades, evitam reprová-las, argumentando que, com as atividades de recuperação, há avanços na aprendizagem delas. Porém, o que relatam sobre essas atividades desenvolvidas com essas crianças está baseado em treino e repetição, sendo questionável se se trata de avanço na aprendizagem ou se é desempenho aceitável em avaliações internas ou externas à escola que resulta em bons índices para a instituição.

Modelo de recomendação de nutrientes para o abacateiro ‘Hass’
Authors:   , Santos Edson Fagne dos
Published: December 2023

As recomendações de adubação para a cultura do abacateiro, muitas vezes são realizadas de forma empírica sem conhecer a real demanda das diferentes cultivares existentes. Assim, é necessário que se conheça a quantidade de nutrientes removidos pelo fruto, durante o processo de colheita, além das quantidades absorvidas que são direcionadas para formação e manutenção dos órgãos da planta. Diante disto, objetivou-se avaliar a partição de biomassa e de nutrientes e eficiência nutricional no abacateiro ‘Hass’. Para obtenção dos dados, foram abatidas plantas referentes ao abacateiro ‘Hass’ provenientes de lavoura comercial pertencente ao Grupo Tsuge na região do Alto Paranaíba-MG. As plantas foram separadas em folhas, frutos, ramos herbáceos, tronco + caule e raízes, além da serrapilheira. Avaliou-se os teores nutricionais em cada órgão da planta e no solo bem como determinou-se o CUB (Coeficiente de utilização Biológico) e o IC (Índice de Colheita). O abacateiro ‘Hass’ acumula aos 30 anos cerca de 655 kg planta-1 de biomassa vegetativa, sendo este acúmulo mais pronunciado entre o sétimo e o décimo ano de cultivo. As plantas de abacateiro ‘Hass’ acumulam aos 30 anos de idade 3698, 460, 2992, 558, 1507 e 873 g planta -1 de N, P, K, S, Ca e Mg e cerca de 3, 198, 5, 6, 16 g planta-1 para o Cu, Fe, Mn, Zn, sendo que esses valores podem ser aumentados de acordo com a produtividade almejada. O S e o P foram os macronutrientes que apresentaram maiores valores de CUB e o N e K obtiveram menores valores. Para os micronutrientes, o abacateiro foi menos eficiente na conversão de Fe em MS e mais eficiente na conversão de Cu. O IC decresce com o aumento da idade da planta para os órgãos folha, fruto e ramo herbáceo e aumenta para tronco + caule. A modelagem da recomendação de nutrientes é uma ferramenta útil para recomendar fertilizantes para o abacateiro permitindo que as recomendações variem conforme a produtividade almejada o teor de nutrientes disponível no solo e serrapilheira do abacateiro ‘Hass’. Contudo, é necessário incorporar procedimentos que possibilitem sua melhoria, principalmente relacionados à taxa de recuperação dos nutrientes pela planta. Palavras-chave: Persea americana Mill..

Assessment of Higher Education Programmes for Enhancing the Postgraduate Community
Authors: Mzini Loraine Boitumelo Boitumelo
Published: December 2023

This article assesses the higher education research capacity building programmes designed to enhance the postgraduate community and scholarly publishing. Post-graduate studies are potential components for promoting knowledge, increasing institutional outputs.  Post-graduate studies are likely to create research profile for students who seek future academic appointments. In spite of that higher institutions in low-income countries face serious challenges in building research capacity. This is compounded by local institutional competition for rankings and ratings. To some extent, investments in research usually take a long time before leading to demonstrable results. Yet again postgraduate students across disciplines feel pressure to publish their scholarship and remain unsure partly due to a lack of explicit training. Once more part of academic written output remains unpublished resulting to grey literature. Publishing requires a cocktail of skills in practical activities, and a broad awareness of theoretical/academic developments and trends. A large number of agencies evolved to offer programmes with the aim to expand research capacity in certain kinds of institutions. Institutions hold opposing mechanisms for supporting and sustaining research capacity among postgraduate students. A desk study approach is considered to collect data. Desktop study reviewed the key strategies, models for building postgraduate research capacity and programmes designed for increasing postgraduate scholarly publishing among the South African universities. The research reveals that the Cooke’s framework potentially offers a mechanism to contribute to the realisation of the research capacity building goals. A set of recommendations are offered for programme improvement.

Published: December 2023

A high degree of weed infestation of agricultural ecosystems poses a significant threat to high crop yields, which determines the problem of weed control as one of the most urgent in steppe agriculture. The research aims to assess the level of total weed density and seed bank of various components of agroecosystems in the steppe zone of Ukraine. The methods used to determine the species composition of weeds, their quantitative and weight accounting and harmfulness were statistical and mathematical. It has been established that the main reason for the high negative impact of weeds is the weed seed bank of soils, which reaches 452 million seeds per hectare in land being actively used for agriculture and 11 million hectares in natural ecosystems. In agroecosystems, the decisive factor for effective regulation of weed seed banks is the sustainability of crops (as part of an ecosystem dominated by 1 plant species), methods of basic tillage and measures to prevent the generative productivity of weeds. According to the impact on the yield of winter wheat, corn, sunflower and spring barley, different tillage systems (ploughing, disc tillage, no-tillage) in the crop rotation were significant, where the no-tillage system was inferior to disc tillage, depending on the fertilization background, by 0.21-0.22 t/ha and ploughing – by 0.19-0.40 t/ha due to increased weed infestation of crops, as well as the presence of a significant amount of carrion and leaf mass of the predecessor on the field surface. The practical value is determined by an improvement of the system of weed control in crop rotations of adaptive agriculture and environmental safety

Paisaje y bagaje histórico en “La cordillera” (2017) de Santiago Mitre
Authors: Pifano Diana
Published: December 2023

En La cordillera (2017) el director Santiago Mitre vuelve a explorar la política a través del personaje de Hernán Blanco, quien, al comienzo de su mandato como presidente de Argentina, se prepara para su primera cumbre de líderes en un hotel en la cima de los Andes. La trama de este thriller alterna entre la vida profesional y personal del presidente ya que, al unísono de las negociaciones de la cumbre, el yerno y la hija de Blanco ocasionan una crisis familiar que amenaza su reputación. Bajo esta presión, tanto las relaciones profesionales como familiares de Blanco comienzan a fracturarse y gradualmente el protagonista se va desligando de colegas y familiares. Ambos aspectos de la vida del presidente confluyen y su ambición desmedida lleva al espectador a cuestionar su carácter moral y preguntarse: ¿hasta dónde será capaz de llegar para beneficiarse a sí mismo?
Basándome en el trabajo de Martin Lefebvre (2011), describo cómo la representación cinemática de la cordillera apoya el aislamiento de Blanco. Usando tomas en gran angular e imágenes altamente iluminadas, Mitre (2017) presenta un paisaje deshabitado e inhóspito que acordona y aísla a los personajes. Posteriormente, me apoyo en las ideas de Harper y Rayner (2010) en Cinema and Landscape, para reflexionar sobre el papel de los Andes en la historia de Latinoamérica y como forman parte del bagaje cultural del espectador. A la luz de esta discusión sobre el paisaje, logro ahondar en el comentario político del filme.

Exposure to gamma irradiation (γ-IR) causes cellular alterations (CA) in animals. Extract of Adansonia digitata and Corchorus olitorius leaves (ADCOL) have been shown to protect against γ-IR-induced CA in rats. Traditionally, the leaves are consumed as part of diets, however, there is paucity of scientific information on the use of ADCOL based-diet (BD) against CA. Thus, the study investigated the effects of ADCOL BD in cellular system of irradiated rats. The objectives of the study were to determine the secondary metabolites in ADCOL, induce cellular alterations in rats and evaluate the protective, ameliorative and toxicity of ADCOL BD on rats. A total of 72 rats (186 ± 4.90g) were used in the 2 phases of this study. In the ameliorative phase, 36 rats were assigned into 6 groups of 6 each; Group I were fed with rat chow and distilled water only, all other groups were irradiated, such that, Groups II III, IV, V & VI were fed rat chow only, 80% inclusion of ADBD, 80% inclusion of COBD, 80% inclusion of combined ADCOLBD and Vitamin-C-BD respectively. Similar design was adopted for protective phase, except that, the rats were initially fed the inclusion diet before irradiation. Micronuclei status were viewed by automated electron microscope, p53 level was determined by enzyme linked immunosorbent assay and antioxidant status of rat were determined by standard methods. Data were analysed using Duncan multiple range test at p<0.05. The findings in this study, were that; secondary metabolites constituents of A. digitata and C. olitorius were alkaloids (78.76 and 72.36g/dl) terpenoids (42.45 and 21.25 g/dl) flavonoids (13.42 and 104.81g/dl) polyphenols and (147.90 and 203.14 g/dl) respectively; γ-irradiation significantly (p<0.05) increased mean number of micronuclei and decreased p53, superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) level in rats; 80% inclusion of A. digitata and C. olitorius leaf-BD significantly (p<0.05) reduced mean number of micronuclei and increased p53, SOD, CAT and GSH level in irradiated rats. The study concluded, that A. digitata and C. olitorius protected cellular damage induced by radiation. Thus, recommending their use against cellular damage.

The computation of state probability distributions at an arbitrary point in time, which in the case of a discrete-time Markov chain means finding the distribution at some arbitrary time step n denoted π^((n) ), a row vector whose i^th component is the probability that the Markov chain is in state i at time step n, and this is the iterative solution methods for transient distribution in Markov chain. In this study, the solutions of transient distribution in Markov chain using Euler and trapezoid methods have been investigated, in order to provide some insight into the solutions of transient distribution in Markov chain, which produce a significantly more accurate response in less time for some types of situations and also tries to get to the end result as quickly as possible with the solution conform with a specified number of well-defined stages is computed for large space Markov chain. Matrices operations, such as the product and matrix inversion are performed and Markov chain laws, theorems, formulas with MATLAB software are utilized. For illustrative examples, the transient distribution vector's π_((i+1) ),i=0,1,2,…, ; is computed for both Euler and Trapezoid methods and their corresponding error when compared with different method. The effect of decreasing the step size using the same infinitesimal generator is examined, also, by taking π_((0) )=(■(1&0&0)) and the length of the interval of integration to be τ = 1, it is observed that the accuracy achieved with the explicit Euler method has a direct relationship with the step size. It is also concluded that the much more accurate results are obtained with the trapezoid method.

This study aims to develop an efficient, portable and ergonomically safe multi-crop slicing machine that can be affordable to small-scale entrepreneurs, evaluate its performance, and determine its slicing efficiency and throughput capacity at different operation speeds. Some of the machine’s major components include the mainframe, outlet, hopper, slicing unit, slicing disc, pulley, electric motor base and bearing. The machine is powered by a single phase and 1hr electric motor. The performance of the machine was conducted with three selected crops (banana, cucumber and carrots); grouped into three categories, namely minimum-sized samples (35 – 54 mm), medium-sized samples (55 – 65mm) and maximum-sized (65 – 75mm); at five machine speeds of 26, 38, 42, 55 and 65rpm. The parameters determined were slicing efficiency and throughput capacity. Results showed that the highest mean slicing efficiency of 87% was attained by the machine when slicing minimum-size cucumbers at a rotational speed of 55 rpm, while the machine attained the lowest mean slicing efficiency of 58% for slicing maximum-sized cucumbers at a rotational speed of 65 rpm. The throughput capacities from the machine were affected by the slicing speeds, which ranged between 21.45 kg/hr to 42.90 kg/hr. The constructed machine demonstrated ability to slice all the selected crops satisfactorily.

Published: December 2023

This study investigated the remuneration level of security guards from Samburu Community working in Nairobi. The study adopted, as its theoretical framework, the Interests Theory of human rights as described by Raz. In examining these issues, the study looked at the following indicators, which provided evidence for granting or non-granting of employee rights: shelter, diet and investments made by the employees; existence of job contracts, insurance cover, retirement benefit plan and health cover; membership to a trade union; promotion at work and salary increment; and the nature of equipment and training for the job. The study involved all security guards from the Samburu community working in Nairobi as the population of study and individual security guards as the unit of analysis. Five areas of the city, that is, Westlands/Kabete, Lavington/Kangemi/Waithaka/Muthaiga/Thika Road, Karen/Lang’ata, South C/South B and Embakasi, were marked out as the places from which the study sample was taken. The study adopted a survey design, and data was collected through questionnaires, which were applied to 200 security guards who had been randomly selected from 5 administrative clusters in Nairobi. The findings indicated that security guards were poorly remunerated. It recommended that the government of Kenya enforce a minimum salary of at least at the level of maximum un-taxable income and proper job contraction for security guards.
A Comprehensive Evaluation of the Impact of Social Media on Mental Health Reveals Noteworthy Effects
Authors: Ikbal Tarik
Published: December 2023

This review explores the impact of social media on mental health, focusing on anxiety, stress, depression, and loneliness. The analysis of extensive research highlights the potential negative effects of social media use on mental well-being. Key findings suggest that frequent social media use is associated with increased anxiety levels due to social comparison, fear of missing out (FOMO), cyberbullying, and information overload. Social media use is also linked to higher levels of stress, with factors such as maintaining a certain image and constant engagement contributing to psychological burden. Excessive use of social media platforms, especially Facebook, is associated with depressive symptoms and poorer mental health outcomes. Furthermore, social media use can paradoxically contribute to loneliness, as superficial online interactions may not provide the same depth and fulfillment as offline connections. The complex relationship between social media and mental health calls for individuals to be mindful of their usage and develop strategies to mitigate potential negative effects. Further research, interventions, and awareness about responsible social media use are necessary to promote positive mental health outcomes.
