YOLOv5s-gnConv: detecting personal protective equipment for workers at height
Authors: Chen Huihua , Li Yaoyu , Wen Huanxi , Hu Xiaodong
Published: September 2023

Introduction

Falls from height (FFH) accidents can devastate families and individuals. Currently, the best way to prevent falls from heights is to wear personal protective equipment (PPE). However, traditional manual checking methods for safety hazards are inefficient and difficult to detect and eliminate potential risks.

Methods

To better detect whether a person working at height is wearing PPE or not, this paper first applies field research and Python crawling techniques to create a dataset of people working at height, extends the dataset to 10,000 images through data enhancement (brightness, rotation, blurring, and Moica), and categorizes the dataset into a training set, a validation set, and a test set according to the ratio of 7:2:1. In this study, three improved YOLOv5s models are proposed for detecting PPE in construction sites with many open-air operations, complex construction scenarios, and frequent personnel changes. Among them, YOLOv5s-gnconv is wholly based on the convolutional structure, which achieves effective modeling of higher-order spatial interactions through gated convolution (gnConv) and cyclic design, improves the performance of the algorithm, and increases the expressiveness of the model while reducing the network parameters.

Results

Experimental results show that YOLOv5s-gnconv outperforms the official model YOLOv5s by 5.01%, 4.72%, and 4.26% in precision, recall, and mAP_0.5, respectively. It better ensures the safety of workers working at height.

Discussion

To deploy the YOLOv5s-gnConv model in a construction site environment and to effectively monitor and manage the safety of workers at height, we also discuss the impacts and potential limitations of lighting conditions, camera angles, and worker movement patterns.

Introduction

Sarcocystis is a genus of cyst-forming parasites that infest both humans and livestock. Some parasites cause clinical and subclinical diseases in their hosts, resulting in economic losses.

Methods

Esophagus, diaphragm, and skeletal muscle from slaughtered sheep and goats were examined macroscopically, microscopically, and ultrastructurally and subjected to DNA analysis.

Results

We isolated macrocysts of S. gigantea and of S. caprafelis moulei from naturally infected sheep (Ovis aries) and goats (Capra hircus). The macrocyst wall thickness was 18.9 µm in sheep and 15.3 µm in goats, and consisted of an inner Periodic acid Schiff- (PAS) negative primary wall and an outer glycoconjugates containing i.e. PAS-positive secondary wall. The walls inner surface was compartmentalized and filled with bradyzoites. In S. gigantea the bradyzoites were approximently 12.3 x 2.6 µm in size, while in S. caprafelis moulei they were 13.9 x 4.4 µm. Ultrastructurally, both species have nearly identical morphology: cauliflower-like protrusions with numerous microtubules and often dendritic-like filaments, branching from the primary wall. The 18S rRNA gene in S. gigantea was 85.9% identical to that in S. medusiformis and 80.4% to the S. caprafelis moulei gene. The 28S rRNA gene in S. gigantea was 94.6% identical to that in S. medusiformis and 97.3% to the S. caprafelis moulei.

Conclusion

This study is the first to (i) detail the ultrastructure of the macrocyst wall of S. caprafelis moulei, (ii) identify S. medusiformis in Iraqi sheep, and (iii) compare the prevalence of macroscopic Sarcocystis at different time periods within the same region. A positive finding was the reduction of macroscopic sarcocystosis occurrences (0.01% in sheep and 0.02% in goats) compared to our previous data from 1992 (4.1%: sheep, 33.6%: goats).
Some Matrix-Variate Models Applicable in Different Areas
Authors: Mathai Arak M.
Published: September 2023

Matrix-variate Gaussian-type or Wishart-type distributions in the real domain are widely used in the literature. When the exponential trace has an arbitrary power and when the factors involving a determinant and a trace enter into the model or a matrix-variate gamma-type or Wishart-type model with an exponential trace having an arbitrary power, they are extremely difficult to handle. One such model with factors involving a trace and a determinant and the exponential trace having an arbitrary power, in the real domain, is known in the literature as the Kotz model. No explicit evaluation of the normalizing constant in the Kotz model seems to be available. The normalizing constant that is widely used in the literature, is interpreted as the normalizing constant in the general model, and that is referred to as a Kotz model does not seem to be correct. One of the main contributions in this paper is the introduction of matrix-variate distributions in the real and complex domains belonging to the Gaussian-type, gamma-type, and type 1 and type 2 beta-types, or Mathai’s pathway family, when the exponential trace has an arbitrary power and explicit evaluations of the normalizing constants therein. All of these models are believed to be new. Another new contribution is the logistic-based extensions of the models in the real and complex domains, with the exponential trace having an arbitrary exponent and connecting to extended zeta functions introduced by this author recently. The techniques and steps used at various stages in this paper will be highly useful for people working in multivariate statistical analysis, as well as for people applying such models in engineering problems, communication theory, quantum physics, and related areas, apart from statistical applications.
Synthesis of Precursors to Ethylene Glycol via the Acid-Catalyzed Carbonylation of Formaldehyde
Authors: Wang Di , Lv Jiangang
Published: September 2023

Methyl glycolate was synthesized as a precursor to ethylene glycol from the acid-catalyzed carbonylation of formaldehyde, followed by esterification with methanol. Homogeneous acids and different solid acids (e.g., resins and zeolites) were used as catalysts, and the effect of the solvent was examined. Afterward, a carboxylic acid protection strategy was proposed. With sulfolane and acetic acid as the mixed solvent, the solubility of CO increases, and the reaction rate can be accelerated. The rapid reaction between acetic acid and glycolic acid inhibits glycolic acid polymerization and pulls the reaction balance to promote the carbonylation reaction rate. Under the optimal solvent system (a molar ratio of acetic acid to sulfolane of 1:5) and the appropriate reaction conditions, the selectivity of the target product is higher than 85%. Solid acid catalysts with a −SO3H or −CF2SO3H functional group are supposed to be efficient in the carbonylation of formaldehyde, based on which a supported Nafion catalyst with a high surface area and total acid content was designed and synthesized. The novel supported Nafion catalyst presents a high total acid content and high Brönsted–Lewis acid ratio due to the characteristics of modified zeolite and, thus, leads to the high reactivity and very low selectivity of the by-product. A possible reaction mechanism is proposed to explain the product’s distribution by ascribing the formation of different products to different types of acid sites.

Published: September 2023

Background and Objectives: Prediabetes is associated with a high risk of developing diabetes and cardiovascular disease. Early treatment with exercise and dietary interventions can reduce the progression of prediabetes to diabetes or even lead to a return of glucose levels to normal. The aim of the study was to evaluate the effect of a dietary supplement with Portulaca oleracea and titrated Cistus creticus extract on the glycemic profile of people with prediabetes. Materials and Methods: Participants were assigned to a dietary supplement with Portulaca oleracea and titrated Cistus creticus extract, along with vitamins and minerals, received once daily for 90 days. Demographics and medical history were obtained, and a complete clinical examination, measurement of somatometric characteristics, and laboratory parameters were performed at baseline. The measurement of somatometric characteristics and laboratory tests were repeated at the end of the study. Results: A total of 26 people with prediabetes participated, 11 females and 15 males. There was a tendency for a decrease in HbA1c after intervention [baseline: 5.9 (5.7–6.1)%; at the end of the study: 5.7 (5.7–6.0)%, p = 0.062] and a significant decrease in fasting glucose levels (from 110.8 ± 7.0 mg/dL to 103.9 ± 10.3, p = 0.005). Fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR) decreased significantly [baseline fasting insulin: 20.7 (9.3–34.20) μU/mL; at the end of the study: 15.1 (8.6–19.0) μU/mL, p = 0.028; baseline HOMA-IR: 3.6 (2.5–8.9); at the end of the study: 3.5 (2.0–4.6), p = 0.035]. Significant reductions were observed in alkaline phosphatase and uric acid levels. No significant change was observed in body weight, body mass index, or waist circumference after the intervention. No treatment-emergent adverse events were observed, and all participants completed the study. Conclusions: The dietary supplement from Portulaca oleracea and titrated Cistus creticus extract, along with vitamins and minerals, may improve the metabolic profile of people with prediabetes.
Effect of Process Variables on Interface Friction Characteristics in Strip Drawing of AA 5182 Alloy and Its Formability in Warm Deep Drawing
Authors: Shrivastava Archit , Digavalli Ravi Kumar
Published: September 2023

Warm forming is widely used to enhance the formability of aluminum alloy sheets. In warm deep drawing, the process variables significantly affect frictional characteristics at the tool–blank interface. It has been a conventional approach to use a constant value of friction coefficients in the finite element (FE) simulations. However, this can occasionally result in suboptimal accuracy of the predictions. In the present work, strip drawing tests were carried out on AA5182 aluminum alloy sheets to investigate the effect of important process variables, namely, temperature, contact pressure, and drawing speed, on the friction coefficient in the warm forming temperature range (100–250 °C) under lubricated condition. The results obtained from the strip drawing tests were used for defining the friction conditions in the simulation of warm deep drawing of cylindrical cups incorporating the variation of the friction coefficient with contact pressure and speed at different temperatures. The Barlat89 yield criterion was used to define the effect of anisotropy in the material. The Voce hardening law and Cowper–Symonds model were used to incorporate the effect of strain hardening and strain rate, respectively, in the simulation. Drawability and peak force were compared with the predictions when a constant friction coefficient was assumed. Warm deep drawing experiments were conducted to validate the predicted drawability and load–displacement curves. It is clearly observed that the accuracy of prediction of the limiting drawing ratio and peak load through simulations is improved by incorporating the effect of pressure and speed on friction coefficient as it captures the local variations of friction during warm deep drawing precisely, rather than assuming a constant average friction coefficient at all the tool–blank contact areas.
Multiagent Coordination and Teamwork: A Case Study for Large-Scale Dynamic Ready-Mixed Concrete Delivery Problem
Authors: Hanif Shaza , Din Shahab Ud , Gui Ning , Holvoet Tom
Published: September 2023

The ready-mixed concrete delivery (RMC) problem is a scheduling problem, where multiple trucks deliver concrete to order sites abiding by hard constraints in a dynamic environment. It is an NP-hard problem, impractical to solve using exhaustive methods. Thus, it requires heuristic-based approaches for generating sub-optimal schedules. Due to its distributed nature, we address this problem using a decentralised, scalable, cooperative MAS (multiagent system) that dynamically generates schedules. We explore the impact of teamwork by trucks on schedule optimisation. This work illustrates two novel approaches that address the dynamic RMC problem; a Delegate MAS approach and a team-extended approach. We present an empirical study, comparing our novel approaches with existing ones. The evaluation is performed by classifying the RMC case study scenarios into unique stress, scale, and dynamism characteristics. With 40% to 70% improvement over different metrics, the results show that both approaches generate better schedules, and using agent teams augments the performance. Thus, such decentralized MAS with the appropriate coordination approach and teamwork can be used for solving constrained dynamic scheduling problems.

Published: September 2023

In many Indian regions, increased wastewater is both a threat to public health and the environment, but it also presents an opportunity as a source of water and nutrients. With less than one-third of India’s wastewater treated and an alarming water scarcity situation, efficient wastewater treatment and reuse schemes are needed to face impending water and fertiliser shortages. This study explores the application potential of wastewater fertigated Short Rotation Coppice systems (wfSRC) as a cost-efficient and promising solution for treating and reusing wastewater in a specific region (400 km2, 184 settlements) of Aligarh (UP), India. Based on real data from a local wfSRC pilot site using bamboo, willow, and poplar, we analysed the system’s treatment performance, nutrient recovery, carbon sequestration potential, land requirements, biomass production potential, and cost–benefit, under various scenarios. The results show that the pilot wfSRC system is efficiently treating 250 m3/day of domestic wastewater on 6864 m2 of land, and serving 2500 people. The land requirements for wfSRC systems vary depending on local conditions (e.g., climate, soil type, wastewater composition) and user demands (e.g., water reuse efficiency, type, and amount of biomass). The calculated areas ranged from 2.75 to 25.7 m2/PE, which equates to a required land area in the whole study region of between 108 and 1006 ha in 2036. This would produce up to 100 DM t/ha/year of valuable biomass. Early local stakeholder involvement and the monitoring of pollutants are recommended as priorities during the planning process for the large-scale implementation of wfSRC systems in India.
Optimization of an Inductive Displacement Transducer
Authors: Mociran Bogdan , Gliga Marian
Published: September 2023

This paper presents the optimization of an inductive displacement transducer or linear variable differential transformer (LVDT). The method integrates design software (SolidWorks 2023), simulation tools (COMSOL Multiphysics), and MATLAB. The optimization phase utilizes the non-dominated sorting genetic algorithm (NSGA)-II and -III to fine-tune the geometry configuration by adjusting six inner parameters corresponding to the dimension of the interior components of the LVDT, thus aiming to improve the overall performance of the device. The outcomes of this study reveal a significant achievement in LVDT enhancement. By employing the proposed methodology, the operational range of the LVDT was effectively doubled, extending it from its initial 8 (mm) to 16 (mm). This expansion in the operational range was achieved without compromising measurement accuracy, as all error values for the working range of 0–16 (mm) (NSGA-II with a maximum final relative error of 2.22% and NSGA-III with 2.44%) remained below the imposed 3% limit. This research introduces a new concept in LVDT optimization, capitalizing on the combined power of NSGA-II and NSGA-III algorithms. The integration of these advanced algorithms, along with the interconnection between design, simulation, and programming tools, distinguishes this work from conventional approaches. This study fulfilled its initial objectives and generated quantifiable results. It introduced novel internal configurations that substantially improved the LVDT’s performance. These achievements underscore the validity and potential of the proposed methodology in advancing LVDT technology, with promising implications for a wide range of engineering applications.
A Tale of Two Strawberries: Conventional and Organic Open-Field Production in California
Authors: Verteramo Chiu Leslie J. , Gomez Miguel I.
Published: September 2023

Organic produce in general is perceived as environmentally superior to conventional produce. This perception is what partially drives some consumers to pay a price premium for organic food. To understand the environmental impact across various categories of both production systems, we performed a life cycle analysis on organic and conventionally produced strawberries in California, following input estimates from extension reports. This study found that organic strawberries performed worse than conventional strawberries in almost all environmental impact categories by unit of land and unit of production. Organic strawberries generate 46% more carbon footprint than conventional strawberries. One of the main environmental impact contributors of organic production is the effect of transportation of compost, manure, and other organic inputs, which are required in large volumes per ha. The contribution of input delivery to total carbon footprint per ha of organic strawberry production is 33%, and for conventional strawberry production the contribution is 8%. Post-harvest processing of strawberries is the activity in both production systems that contributes the most to total GWP per ha of production, up to 40% for organic and 60% for conventional strawberries.

The Effect of a Combination of Nitrite with Lactate, and Sorbate on Physical, Chemical, Antioxidant and Sensory Properties of Beef Mortadella during Storage
Authors: Farhi Sarra , Al-Abdullah Al-Sawalha Basem
Published: September 2023

This study aimed to evaluate the effect of a combination of nitrite with lactate and/or sorbate on the physical, chemical antioxidant, and sensory properties of beef mortadella during storage. Five treatments (Tr1, Tr2, Tr3, Tr4, and Tr5) of beef mortadella were prepared and stored at 4°C. Tr1 and Tr2 with 120ppm and 60ppm of nitrite (NaNO2) respectively, were controls. Tr3 was prepared with the addition of Na-nitrite and Na-lactate, Tr4 with Na-nitrite and K-sorbate, and Tr5 with a combination of all of them. Samples were tested for chemical composition, pH, hunter color, thiobarbituric acid values (TBA), residual nitrite concentration, and sensory characteristics during storage. Additionally, the residual nitrite content of 12 different meat products was estimated. Nitrite had a slight effect on the chemical composition. At the end of storage, TBA values did not exceed 2mg/Kg malondialdehyde in all treatments. However, Tr2 and Tr5 had lower TBA values. The highest pH value recorded was for Tr5 (6.33). A sharp decrease in nitrite level was found in all treatments. During storage, Tr3, Tr4, and Tr5 were more stable in terms of color than the control samples. Treatments with 60ppm nitrite only, or combined with an organic acid, were well-accepted from a sensorial aspect. Flavor and aroma scores were statistically similar with ratings between 5.89-6.47/9. Nitrite reduction in meat products is considered a markedly healthier practice.

Published: September 2023

Black cumin (Nigella sativa L) is an important spice and medicinal plant cultivated in Ethiopia. However, the seed yield of the crop is low due to low soil fertility and poor soil fertility management. A field experiment was conducted to determine the effect of nitrogen and phosphorus (NP) and blended nitrogen, phosphorus, sulfur, and boron (NPSB) fertilizers on seed yield and yield components of black cumin. The experiment consists of three levels of N/P2O5 (20/15, 40/30, and 60/45 kg N/P2O5 ha–1 in the form of UREA and tri-super phosphate); and four levels of blended NPSB (0, 50, 100 and 150 kg ha–1) laid in RCBD design arranged in a factorial and replicated three time. The research was conducted during the 2017/18 primary season in the central highlands of Ethiopia. The interaction of NP and blended NPSB significantly influenced yield and yield components (P ≤0.01). The application of 40/30 kg N/P2O5 and 150 kg blended NPSB ha–1 resulted in the highest seed yield (1.85 t ha–1) and the highest net benefit of (78,137 ETB ha–1). Therefore, the application of 40/30 kg N/P2O5 and 150 kg NPSB ha–1 resulted in more than double the current national average yield and benefits black cumin-producing farmers in the central highlands of Ethiopia.

Objectives The objective of our study was to analyse the presentation of various adnexal masses suspicious of malignancy (borderline and
malignant) in terms of type of malignancy, associated tumor markers, stage-based management, need for adjuvant therapy and follow up in the
form of RIOT (Return To Intended Oncologic Therapy) and disease specic survival (DSS) for malignant masses. Methods & Materials A veyear study was conducted at All India Institute of Medical Sciences, Jodhpur on 163 patients who underwent surgery for suspicious or
indeterminate ovarian neoplasms on pre-operative work up. The oncological outcomes of patients were analysed after histopathological
conrmation of malignancy. Survival analysis was done using Kaplan-Meier method. Results Out of 163 cases of suspicious ovarian tumors, 56
(34.3%) were malignant, 13 (8.33%) were borderline and 94 (57.6%) were benign. Among malignant masses high grade serous
cystadenocarcinoma formed the majority, while mucinous cystadenoma was the most common benign mass found. Cytoreductive surgery (CRS)
was done in all cases of malignancy and chemotherapy offered as per the stage of disease likely neoadjuvant (NACT) and adjuvant. Conclusion
The study presents oncological presentation and outcome of ovarian neoplasms in a budding cancer unit of a tertiary care hospital. We found that
DSS was better for Epithelial ovarian cancers (EOC) as compared to Germ Cell Tumors (GCT), and early-stage disease as compared with advanced
stage disease but statistical signicance was not reached. There was no evidence that NACT followed by interval debulking surgery (IDS) for
advanced ovarian malignancy was superior to cytoreductive surgery followed by adjuvant chemotherapy

case represents a very unique variant of a single coronary artery arising from the left coronary sinus and an anomalous origin of the right coronary
artery (RCA) as a branch of the mid-segment of the left anterior descending artery (LAD). The RCA takes a course anterior to the pulmonary artery
to reach the right atrioventricular groove. This anomaly was characterized using CT coronary angiography. It is presumably a benign coronary
anomaly, however, detection of such an anomaly is of paramount importance as occlusion of the main stem could result in catastrophic future
complications.

Introduction:The incidence of kidney stone disease has markedly increased during past 2 decades worldwide. With this dramatic increase in stone
disease incidence and prevalence, use of Percutaneous Nephrolithotomy (PCNL) to treat large stone burden has continued to increase. Despite
continuous renements in surgical techniques and technology, overall complication rate of PCNL remains higher. This study was undertaken to
understand role of Guy's stone scoring system, their feasibility, reproducibility, reliability and superiority for assessing their relative predictive
value for Stone Free Rates (SFR) and surgical outcomes of PCNL, based upon our observations and overall results. Materials And Methods: A
prospective observational study was conducted in the department of Urology at a tertiary care centre over a period of 18 months in which all
patients with renal stones who fullled all inclusion and exclusion criteria and underwent Percutaneous Lithotripsy surgery were enrolled into the
study. Guy's stone score was calculated for all the patients preoperatively and its role was assessed to determine the relative predictive value for
stone free rates and surgical outcomes of PCNL. Results: The stone free rates as per Guy's stone scoring system were: The complications observed
as per Clavien Grade 1 were in 11(16.67%) cases, Grade 2 in 21(31.82%), cases, Grade 3a in 3(4.54%) cases. No death was noted. The stone free
rates according to Guy's stone score were 16/16 cases (100 %) in Grade 1, 28/30 cases (93.33 %) in grade 2, 3/11 cases (27.27 %) in Grade 3 and 1/9
cases (11.11 %) in Grade 4. Conclusion: Guy's scoring system is simple, easy to perform, and reliable system to grade stone complexity before
PCNL. Guy's scoring system divides the renal stone into 4 different grades as per the complexity. Based on the complexity and grading of stone,
Guy's scoring system has a strong positive correlation in predicting peri-operative outcomes like no. of puncture, total operative time, and length of
hospital stay. Guy's scoring system has also good positive correlation with both stone free rate and rate of postoperative complications
A PROSPECTIVE STUDY OF FUNCTIONAL OUTCOME OF CLOSED DISPLACED SHAFT CLAVICLE FRACTURES TREATED WITH INTRAMEDULLARY NAILING
Authors: Bhinde Sandeep , Dhanger Sunil , Singh Vivek
Published: September 2023

Introduction: The clavicle is one of the most commonly fractured bones accounting for 2.5– 4% of all fractures. 69 – 82% of these occur in the
middle third of the clavicle, 73% of which are displaced midshaft clavicular fractures. Intramedullary xation for clavicular fractures was rst
described by Peroni in 1950. The use of a TENS nail carries the advantages of less soft tissue compromise, less operative time, better cosmetic
results, and load-sharing xation with relative stability that encourages copious callus formation. A prospective review of Material and Method:
20 patients in our institute R.D.Gardi Medical, College, Ujjain (M.P.) between September 2019 to Dec 2022 with displaced midshaft clavicle
fractures and treated with TENS nailing was carried out. All the patients had Functional evaluation using constant scores, which was done at 6 and
12 weeks. Out of 20 patients, 6 (30%)patients had union time between 6-8 weeks, 10 (50%) Results: patients had union time between8-10 weeks,
3 (15%) patients had union time between 10-12 weeks, and 1 (5%) patients had union time between 12-16weeks. Out of 20 patients, 12 patients
(60%) functional evaluation using a constant score is excellent and 8 patients (10%) functional evaluation using a constant score is good.
Conclusion: The intramedullary xation using nails of midshaft clavicle fractures is a safe, minimally invasive technique in indicated cases, and in
our hands, it provides good functional outcomes and cosmetic outcomes.

New series of co-ordination compounds of some transition metal ions [Zn(II), Ni(II), Cu(II)] of synthesized ligand (4- [2{5-[4-Nitrobenzylidene)-
amino]-[1,3,4]thiadiazole- 2yl}phenylimino)-methyl]-phenol. These new prepared metal complexes and Schiff base ligand were characterised by
elemental microanalysis (CHNSO), FTIR, UV-Vis, 1H-NMR, thermal analysis (TGA-DTA), magnetic susceptibility and molar conductance.
Accordance to the obtained data all the prepared complexes were non-electrolytic. On the basis of the instrumental results, structures of metal
complexes have been proposed. From the spectral data it is revealed that all prepared complexes exhibit 2:1 (ligand: metal) ratio. Thermal data
shows degradation of these complexes.
A határ variációi Hunyady Sándor prózájában
Authors: Kovács Krisztina
Published: September 2023

Hunyady Sándor kulturális mixitást sűrítő élettereinek lajstromozásához a térpoétikai beszédmód fontos elképzeléseinek, téziseinek áttekintése szükséges. A dolgozat e modellek szépirodalmi szövegekre alkalmazható szempontjaira fókuszál, a térpoétikai diskurzus reprezentáns teoretikusainak koncepcióit hasznosítja. A Hunyady életvitelétől és élettereitől elválaszthatatlan gazdag identitásminták részben utazás közben felfedezett helyei, a kolozsvári, budapesti, bácskai, partiumi vagy erdélyi szcénák olvasásához szükséges kategóriák, értelmezésükhöz a határ mintázatainak, az éjszakai közeg elmosódó határvonalainak, a város mitologémájának körbejárásával kerülhetünk közelebb. A dolgozat a határon levés néhány kategorizálható példáján keresztül, Hunyady Sándor prózájának térformáit szemügyre véve, az alkotói életművet a korszak és a térség élményét kifejező, annak térről szőtt vízióihoz simuló, a modernség szépirodalmi terepeinek tendenciáiban helyet találó univerzumként kíséreli meg értelmezni.
Auditoria interna governamental: uma revisão rápida das alterações na forma de atuação a partir da publicação da IN SFC nº 3/2017
Authors: Oliveira Patricia Alvares de Azevedo , Guedes Araujo Fernanda , De Oliveira Silva Gabriela
Published: September 2023

Decorridos quase seis anos após a publicação do Referencial Técnico da Atividade de Auditoria Interna Governamental do Poder Executivo Federal, esta revisão rápida visa avaliar as evidências das alterações na forma de atuação das unidades de auditoria interna governamental com a publicação da Instrução Normativa SFC nº 3/2017. Por meio de busca sistematizada no Portal de Periódicos CAPES, foram selecionados estudos contendo análise da forma de atuação da auditoria interna governamental em organizações públicas federais antes e após a publicação do Referencial Técnico (2012 a fevereiro de 2023). Foram identificadas 381 publicações nas bases de dados. Após a remoção das publicações duplicadas, 319 foram avaliadas em relação ao título e resumo para verificar se atendiam aos critérios de inclusão. Nessa primeira triagem, 286 registros foram excluídos. Os 33 remanescentes foram avaliados em sua íntegra, selecionando-se 10 que atendiam aos critérios de elegibilidade e forneceram elementos para análise da abrangência, planejamento, execução e comunicação das unidades de auditoria interna governamental. Os resultados mostram um alinhamento da atuação das unidades de auditoria interna enquanto terceira linha de defesa, em consonância com o que preconiza o Referencial Teórico, mesmo para os estudos que se referiram a período anterior à publicação da IN. Quando à operacionalização das atividades de auditoria interna, os estudos demonstram uma qualificação da etapa de planejamento após a publicação do normativo, não tendo sido verificada melhoria significativa nas etapas de execução e comunicação. Considerando a ausência de artigos sobre a atuação dos órgãos do Sistema de Controle Interno do Poder Executivo Federal após a publicação da IN, a condução de novos estudos é recomendada, para compreender de que forma o Referencial modificou a forma de atuação desses órgãos.

Published: September 2023

Os manguezais são ecossistemas que abrigam grande biodiversidade vegetal e animal, com papel importante na ciclagem de matéria orgânica e na manutenção dos ecossistemas costeiros, sendo inclusive considerados Áreas de Preservação Permanente. Compreender e caracterizar as propriedades das espécies vegetais do mangue a partir de medidas de reflexão da luz - fotogrametria - para ampliar o entendimento de processos naturais e antrópicos e seus efeitos sobre o manguezal é vital para a realização de previsões e políticas públicas. Este estudo foi realizado na localidade de Acupe, na cidade de Santo Amaro, Bahia, Brasil, utilizando técnicas de geotecnologia, como a aerofotogrametria e técnicas de processamento digital de imagens, além de sensores multiespectrais em multibandas de análise. A partir das coletas, foi verificada a saúde vegetal por meio do índice de vegetação por diferença normalizada. Os resultados apresentam os valores correspondentes à saúde vegetal da região, caracterizando áreas sadias e regiões potencialmente contaminadas, colaborando para a modelagem ambiental da área e levantamento de banco multiparâmetro da Baía de Todos os Santos.

O potássio e o nitrogênio são os nutrientes mais demandados na manutenção da pastagem e, por isso, objetivou-se identificar uma combinação de nitrogênio e potássio que maximize o desenvolvimento de cultivares de Megathyrsus maximus (sin. Panicum maximum). Foram realizados quatro experimentos em casa de vegetação na Universidade Federal de Rondonópolis. Os experimentos foram realizados com os cultivares Mombaça (Experimento 1 e 2) e Zuri (Experimento 3 e 4). Para cada capim testado, realizou-se dois experimentos simultaneamente e cada experimento consistiu em duas doses de nitrogênio: 140 e 280 mg dm-3 associadas a doses de potássio. Em todos os experimentos, os tratamentos consistiram em cinco doses de potássio (0, 70, 140, 210 e 280 mg dm-3). As parcelas experimentais foram vasos de 5 dm3 e as avaliações foram realizadas quando os capins atingiram altura de 60 cm. O potássio não influenciou o número de folhas por perfilho e filocrono dos capins Mombaça e Zuri e a densidade populacional de perfilhos do capim-mombaça. Para o capim-zuri, independente da dose de nitrogênio, houve aumento da densidade populacional de perfilhos até a dose de potásiso de 70 mg dm-3. Na dose de nitrogênio de 140 mg dm-3 evidenciou-se que houve incremento na massa de forragem do capim-mombaça e zuri até as doses de potássio de 70 mg dm-3, respectivamente. Quanto a dose de nitrogênio de 280 mg dm-3, a maior massa de forragem do capim-mombaça e zuri foi observada na dose de potássio de 140 e 210 mg dm-3, respectivamente. A massa seca de cada lâmina foliar, independente do capim e da dose de nitrogênio aumentou até a dose de 70 mg dm-3. Para a adubação de cultivares de Megathyrsus maximus, a combinação de nitrogênio:potássio é aproximadamente de 1,3 a 2:1.
