AN IMPROVED ENERGY SEGMENTATION BASED STEREO MATCHING ALGORITHM
Authors: Xiao J. , Yang L. , Zhou J. , Li H. , Li B. , Ding L.
Published: May 2022

Abstract. The stereo matching algorithm is commonly used in dealing with disparity discontinuous areas. However, the algorithm may have higher computational complexity and lack of well-aligned input images. To improve that, this paper presents an improved energy segmentation based stereo matching algorithm. The proposed algorithm incorporates gradient information of each segmented region into the energy function according to the facts that gradients inside the same segmentation should be closer than those from different segmentation. The invalid matching pixels are interpolated with vertical-horizontal nearest neighboring pixels to keep the consistency of stereo image pairs in the initial disparity map. Thus, the proposed method can reduce the deviations and the number of executions of the Random Sample Consensus (RANSAC) which arises from misalignment of input image pairs. Experiments results demonstrate that the proposed algorithm has a better disparity result while the running time is decreased by about 20%.

Abstract. Introduction: Local antimicrobial delivery via calcium sulfate
(CaSO4) beads is used as an adjunctive treatment for periprosthetic
joint infection. There is limited clinical information describing the
performance of antimicrobial-loaded CaSO4 (ALCS) in large-scale applications. We developed a simulated large joint model to study properties
of eluting ALCS. Methods: The in vitro testing platform was an adapted
standardized model for tribological testing of prosthetic total hips and
total knees (ASTM F732). The model was 70 mL total fluid volume, 25 % bovine serum, and 75 % phosphate-buffered saline, using ISO standard 14242-1 for human synovial fluid simulation. Four brands of CaSO4 were
evaluated. Each 10 mL of CaSO4 was loaded with 1.2 grams (g) of tobramycin and 1 g of vancomycin powders. A 35 mL bead volume, equaling 175 beads, of each product was placed in incubated flasks. The test period was 6 weeks with scheduled interval fluid exchanges. Fluid samples were tested
for antibiotic and calcium concentrations and pH. Results: Antibiotic elution showed an initial burst on Day 1, followed by a logarithmic
reduction over 1 week. Tobramycin fully eluted within 2.5 weeks. Vancomycin showed sustained release over 6 weeks. Calcium ion concentrations were high, with gradual decrease after 3 weeks. All four CaSO4 products
were inherently acidic. Fluid became more acidic with the addition of
antibiotics primarily driven by vancomycin. Discussion: Clinicians should be
cognizant of tobramycin elution burst with ALCS in large loads. The main
driver of acidic pH levels was vancomycin. We propose that joint
complications may result from lowered fluid acidity, and we suggest clinical study of synovial pH.

Published: May 2022

Abstract. Debris flows affect people and infrastructure around the world, and as a result, many numerical models and modelling approaches have been developed to simulate their impacts. Observations from instrumented debris-flow channels show that variability in inflow depth, velocity, and discharge in real debris flows is much higher than what is typically used in numerical simulations. However, the effect of this natural variability on numerical model outputs is not well known. In this study, we examine the effects of using complex inflow time series within a single-phase runout model utilizing a Voellmy flow-resistance model. The interactions between model topography and flow resistance were studied first using a simple triangular hydrograph, which showed that simulated discharges change because of local slopes and Voellmy parameters. Next, more complex inflows were tested using time series based on 24 real debris-flow hydrographs initiated from three locations. We described a simple method to scale inflow hydrographs by defining a target event volume and maximum allowable peak discharge. The
results showed a large variation in simulated flow depths and velocities
arising from the variable inflow. The effects of variable-inflow conditions
were demonstrated in simulations of two case histories of real debris flows,
where the variation in inflow leads to significant variations in the simulation outputs. The real debris-flow hydrographs were used to provide an indication of the range of impacts that may result from the natural
variability in inflow conditions. These results demonstrate that variation in
inflow conditions can lead to reasonable estimates of the potential variation in impacts.
Towards accurate quantification of ice content in permafrost of the Central Andes – Part 1: Geophysics-based estimates from three different regions
Authors: Hilbich Christin , Hauck Christian , Mollaret Coline , Wainstein Pablo , Arenson Lukas U.
Published: May 2022

Abstract. Increasing water scarcity in the Central Andes due to
ongoing climate change recently caused a controversy and debate on the
significance of permafrost occurrences for the hydrologic cycle. The lack of
comprehensive field measurements and quantitative data on the local
variability in internal structure and ground ice content further exacerbates the situation. We present field-based data from six extensive geophysical
campaigns undertaken since 2016 in three different high-altitude regions of
the Central Andes of Chile and Argentina (28 to 32∘ S). Our data
cover various permafrost landforms ranging from ice-poor bedrock to ice-rich
rock glaciers and are complemented by ground truthing information from
boreholes and numerous test pits near the geophysical profiles. In addition
to determining the thickness of the potential ice-rich layers from the
individual profiles, we also use a quantitative four-phase model to estimate
the volumetric ground ice content in representative zones of the geophysical
profiles. Our analysis of 52 geoelectrical and 24 refraction seismic
profiles within this study confirmed that ice-rich permafrost is not
restricted to rock glaciers but is also observed in non-rock-glacier
permafrost slopes in the form of interstitial ice, as well as layers with
excess ice, resulting in substantial ice contents. Consequently, non-rock-glacier permafrost landforms, whose role for local hydrology has so far not
been considered in remote-sensing-based approaches, may be similarly
relevant in terms of ground ice content on a catchment scale and should not
be ignored when quantifying the potential hydrological significance of
permafrost. We show that field-geophysics-based estimates of ground ice
content, while more labour intensive, are considerably more accurate than
remote sensing approaches. The geophysical data can then be further used in
upscaling studies to the catchment scale in order to reliably estimate the
hydrological significance of permafrost within a catchment.
Teaching economic statistics in the internet era
Authors:   University of Ljubljana, Bregar Lee
Published: May 2022

For decades, the course on economic statistics has been a vital part of the curriculum at the University of Ljubljana’s Faculty of Economics. The course aims (1) to deepen students’ understanding of the use of statistical information in decision-making processes at all society levels, and (2) to teach students how to find relevant statistical data and to use them appropriately in the statistical analysis of economic, business and social problems. Implementation of these objectives relies heavily on the use of real-life data, mostly available from official statistics. The advent of electronic data media (particularly Internet) opened new perspectives and approaches to realisation of the course objectives. The paper outlines and evaluates the evolution of teaching methods used in the course in the last decade, ranging from the use of a stand-alone CD-ROM ten years ago, to integration of Internet as an inherent part of the course through diverse applications (an on-line textbook, e-research seminars, e-assignments, etc.). Based on this experience, the purpose of the paper is to discuss the current position of economic statistics as a university course, and its potential role in the knowledge society.

This paper describes a number of generally accessible web-based tools the authors developed over the last couple of years and used in several statistics courses, ranging from the introductory statistics course to a specialized design of experiments course. The first set of tools (VESTAC) illustrates statistical concepts, the second one (VIRTEX) consists of virtual experiments. We discuss some of our experiences with regard to the development and maintenance of these tools and their use in ex cathedra teaching sessions, in guided practice sessions and in student projects. Finally we discuss a third type of tools: distance experiments.

Authors:   University of Granada, Godino Juan , Ruiz Francisco ,   University of Granada, Roa Rafael ,   University of Granada, Pareja Juan ,   University of Granada, Recio Ángel ,   University of Córdoba
Published: May 2022

The aim of this paper is to provide some information to guide the use of Internet interactive resources to teach Statistics in primary and secondary school. We identify key variables, possible cognitive effects and potential semiotic conflicts in two "stat-applets" from the NCTM Standards server. We conclude with some hypotheses about the positive effects of using these resources as computing and display tools, that might favour changes in the types of data analysis tasks, help discussions in the classroom, and amplify conceptual understanding. Even recognising these improvements, we should not forget the statistical objects’ complexity, and the students’ potential symbolic conflicts, which to overcome will require the teacher’s awareness, the planning of appropriate interaction pattern and the improvement of the software.
Overview of online teaching and internet resources for statistics education
Authors:   Swinburne University of Technology, Phillips Brian
Published: May 2022

Over the past few years there has been a big increase in the use of the Internet as a resource for helping teach most subjects, including statistics, especially at the post secondary level. This varies from the fairly simple use of the Web as a place to store and disseminate information and provide efficient means of communication, to complete web based courses on statistics. This paper will look at some of the issues in online learning, and particularly at a range of websites that utilise the different aspects of the Internet for the improvement of the teaching of statistics. These include National Statistical Agencies, statistics courses, statistics calculators, probability, history, assessment, datasets useful in the teaching and research in statistics, interactive applets which aim to help students with the development of statistical concepts and explanatory descriptions of statistics techniques. These developments mainly occur in the teaching of introductory statistics, a subject taken by many students at the post secondary level.
Statistics in the classroom learning to understand societal issues
Authors:   Director General - Marketing and Information Services Statistics Canada, Podehl Martin
Published: May 2022

The role of a National Statistical Office is to produce the official statistics for its country and to help citizens understand the issues underlying the society and economy. Reams of statistical tables cannot do the job alone: to become ‘information’, statistics must be analyzed and portrayed effectively for the target audience, i.e. citizens of all ages. Students (high school and university) can most easily be reached through the Internet. Not only has Internet access the highest rate among the young, but a website is also very cost-effective to make material available in formats and in quantities which would not have been possible in the paper age. The availability of such information, however, must be promoted to students and teachers and efforts must be made to show them the relevance of the material for the classroom. This paper will describe the activities, their results, and lessons learned from the statistical learning resource and education outreach programs in Statistics Canada.
Extending the Journey toward a Virtual Introductory Statistics Course
Authors:   University of Georgia, Wisenbaker Joseph
Published: May 2022

Drawing from web-based materials previously developed to supplement on-campus offerings of an introductory statistics course for graduate students in education, the author made an initial offering of an on-line virtual class in the fall of 2001. Poor student performance and dissatisfaction with this initial course organization led to a deeper reading of the literature on online teaching in general and the online teaching of statistics in particular. A much greater degree of instructor supplied organization, direction and interaction were incorporated into another offering of the course during the spring of 2003. Final examination scores and course evaluations improved markedly over the first on-line offering but remained somewhat lower and more variable than the results from on-campus offerings of the same course. Suggestions for improvements are offered based on instructor observations and student feedback.
Interrelated learning and working environments for supporting the use of computer tools in introductory classes
Authors:   University of Kassel, Biehler Rolf
Published: May 2022

At the department of mathematics & informatics in our University we are in the process of redesigning our introductory course on stochastics (probability and statistics) for future mathematics teachers. In this course we now use the software FATHOM, which students learn as a (cognitive and culturally mediated) tool for exploratory data analysis, for simulation and for inferential statistics as well as a tool for experimenting with statistical methods. We use various types of Internet based materials to support the learning process of our students. Experimental learning environments and working environments containing data and exploratory guides are constructed with FATHOM. FATHOM offers meta-medium and meta-tool capabilities that offer high adaptability and versatility for the teacher of a course. In addition, we have developed Java applets, screen videos and web-based hypertexts as further supporting materials.

Teresa de Ávila, la prudente: confesionalización y antimaquiavelismo en Juan de San Pedro y Ustárroz (1609-1614)
Authors: Macías Facundo Sebastián
Published: May 2022

El presente trabajo tiene como objetivo estudiar la prosa de Juan de San Pedro y Ustárroz y tratar de vincular sus textos antimaquiavélicos con su vita latina dedicada a Teresa de Ávila. Observaremos cómo un concepto aparentemente desconectado, la prudencia, es una pista sintomática importante para ver que su hagiografía, lejos de ser solo un texto orientado a la construcción del santo como el católico perfecto para la canonización, también delata la anticipación de su posterior antimaquiavelismo político que promueve la afirmación de la autoridad política basada en la moral católica ortodoxa. Veremos entonces en sus palabras un intento singular de promover inequívocamente un marco confesional para la clase dominante europea basado en el ejercicio de gobierno conventual para el conjunto de los reinos católicos.

Published: May 2022

El presente trabajo pretende un acercamiento a un tema difícil de conocer como es el comercio interior. Para ello nos centramos en un estudio de caso representativo, en parte, de las ferias a la vez que posee ciertas singularidades. Se trata de la feria de Guadajoz, una villa en término de Carmona (Sevilla), pero bajo la jurisdicción de la Casa de Arcos. Esta circunstancia provoca que los intereses señoriales entren en colisión con los de realengo, representados por la ciudad de Carmona y la Real Hacienda. La documentación disponible nos permite trazar una larga evolución de las principales características de una feria comarcal y regional desde sus orígenes hasta su desaparición.

Forensic Science in The Nigerian Criminal Justice System
Authors: Keltus Kelvin
Published: May 2022

Abstract This research aimed at assessing the application and impact of forensic science in the Nigerian criminal justice system by making reference to certain components of forensics that are relevant to the criminal justice system. Such components include, Deoxyribonucleic Acid (DNA) analysis, Fingerprint analysis, Polygraph test, Ballistics, Forensic anthropology, Forensic pathology and Computer forensics. In the course of this research, it was found that establishing certain types of evidence such as fingerprint impressions and DNA, against accused persons was difficult due to the absence of sophisticated forensic laboratories and this hindered conviction of such persons. In view of this problem, this research recommends for proper training of law enforcement agencies in terms of how crimes and crime scenes are handled and also the establishment of sophisticated forensic labs where evidence and accused persons can be tested in order to determine their guilt or innocence, thereby easing the administration of justice in Nigeria. Keywords: forensic science, Nigerian criminal justice
Impact of COVID-19 Pandemic on Nigerian Exports
Authors: Winifred Chinyere Uchendu , Aras Osman Nuri
Published: May 2022

Abstract The paper set out to evaluate the impact of the COVID-19 pandemic on Nigerian exports. The Coronavirus was first detected in Wuhan, China but it quickly spread around the world and was declared a global pandemic on 11th March 2020 by the World Health Organization (WHO). Various disruptive preventive public health policies were rolled out to control its spread. These policies and the severity of the negative health effects of the virus affected the global economic activities including Nigeria adversely. Using an Ordinary Least Square (OLS) regression and variation analyses, the paper found that the pandemic impacted negatively on total exports but more significantly on crude oil exports and less on non-crude oil and non-oil exports. The results reinforce the generally held view that Nigeria needs to diversify its exports away from crude oil so as to minimize the impact of negative external shocks on Nigerian exports and economy.

Investigation of Nigeria’s Comparative Advantage for the African Continental Free Trade Area
Authors: Alan Eze Ifeanyi , Nuri Aras Osman
Published: May 2022

Nigeria’s comparative advantage for the African Continental Free Trade Area (AfCFTA), has been investigated by this work. The specific objectives of this study are calculating the Revealed Comparative Advantage (RCA) and the Revealed Symmetric Comparative Advantage (RSCA) of Nigeria, and computing and comparing the Revealed Comparative Advantage (RCA) and the Revealed Symmetric Comparative Advantage (RSCA) of Nigeria, Ghana and South Africa. Time series data of Nigeria’s, Ghana’s and South Africa’s export products namely raw materials, intermediate goods, consumer goods and capital goods were obtained from the World Integrated Trade Solution (WITS). The RCA and RSCA of raw materials, intermediate goods, consumer goods and capital goods were computed using the Balassa index, and it was found that Nigeria has comparative advantage in the export of raw materials but has comparative disadvantage in the export of intermediate goods, consumer goods and capital goods. Compared to Ghana and South Africa, Nigeria can profitably export raw materials to AfCFTA trade partners because, though Ghana and South Africa also have comparative advantage in the export of raw materials, theirs is lesser than Nigeria’s. Unlike Nigeria, Ghana and South Africa have relative advantage in intermediate goods export trade. In the export of consumer goods, Nigeria, Ghana and South Africa all have comparative disadvantage, but the position of South Africa is better than that of Nigeria and Ghana. Similarly, Nigeria, Ghana and South Africa have comparative disadvantage in the export of capital goods, however, the position of South Africa is better than those of Nigeria and Ghana. Based on the findings, this study recommends that Nigeria should continue to strengthen its raw materials exports and at the same time, pursue policies and programmes that would improve the comparative advantage positions of its intermediate goods, consumer goods and capital goods export trade. In the area of trade negotiations, the findings of this study has been recommended to the Nigerian Office for Trade Negotiations (NOTN) for adoption in its preparations of guidelines on the rules of origin for stakeholders’ negotiations under AfCFTA Key words: Revealed Comparative Advantage, Revealed Symmetric Comparative Advantage, Goods, Free Trade Area, Nigeria.

Introduction: Strangulation is a common presentation of acute abdominal wall hernias that usually requires emergency surgery. The aim of this report is to propose a “reverse strategy” combining an open mesh-based anterior approach followed by a “conversion” to laparoscopy for the treatment of strangulated hernias. Materials and Methods: A 68-year-old male patient came to the emergency room of our university hospital with a non-reducible left groin hernia. The CT scan demonstrated a left groin strangulated hernia with doubtful viability of the involved bowel loop. We decided to perform a transversal inguinotomy followed by a laparoscopic approach through the inguinal ring. Results: The patient was discharged after four days in perfect general condition, with normal bowel function and no postoperative pain. Conclusion: We propose this unconventional conversion from open to laparoscopic surgery as a new indication for the laparoscopic approach in emergency hernia surgery. We hope it can be used as a gold option for the surgical treatment of strangulated hernia in selected cases.

Background: Ventral hernia is a common occurrence in patients undergoing solid organ transplant (SOT) and who require complex abdominal wall reconstruction (CAWR). The aim of this study was to analyze the outcomes of CAWR in SOT patients in a tertiary center. Methods: We performed a prospective cohort study in patients who underwent CAWR with biological mesh at our center from January 2016 to November 2021. As per the study protocol, all patients will be followed for 3 years. Results: During the study period, we performed CAWR in 38 SOT patients. The mean age (Standard Deviation: SD) was 61 (9.5) years and the majority were males (68%). Mean body mass index (SD) was 30.3 (5.5) kg/m2 and hernia repair was performed electively in 33 patients. The majority (82%) of the hernias were less than class 2 with a median mesh size (interquartile range) of 600 (400-800) cm2. Seventy-nine percent of patients were liver transplant recipients and the mesh was placed sub-lay (retro-rectus) (82%); the most common technique was posterior component separation (82%). Five patients (13.2%) had surgical site infection and 4 (10.5%) had unplanned reoperations. None of the patients died postoperatively and the 30-day readmission rate was 21%. Three patients (7.9%) had recurrence during follow-up and all of them underwent reoperation. Conclusions: Complex abdominal wall reconstruction (CAWR) using biologic mesh for solid organ transplant patients with ventral hernia is safe and has low recurrence when performed by a dedicated CAWR team.

Published: May 2022

Introduction: Periarticular multimodal analgesic injection associates with less postoperative (post-op) pain after total knee arthroplasty (TKA) with less opioid consumption. The combination of additives and dosage are various and controversial. Evidence of ketorolac compared to triamcinolone as an additive is limited in terms of efficacy and safety. Materials and Methods: Fifty-six patients with unilateral TKA were randomized to receive either 60mg ketorolac or 80mg triamcinolone acetonide as cocktail additives in periarticular injection. Significant threshold was considered if the adjusted mean difference of morphine consumption was greater than 3mg at any timepoint. The primary outcomes were morphine consumptions at immediate post-op, 24 hour (h), 48h, and 72h post-op. Pain visual analogue scale (VAS), knee range of motion, straight leg raising ability, and adverse events were secondary outcomes. Results: Adjusted mean differences (ketorolac-triamcinolone) in morphine consumption were -0.4, 2.5, 2.6, and 2.3mg at given timepoints without significance. No difference observed in pain VAS at rest and during motion, post-op knee extension, and straight leg raising ability. However, post-op knee flexion was significantly higher in triamcinolone group at any timepoints (mean differences 10.3, 10.6, and 9.7, respectively, p<0.05). Conclusions: Periarticular analgesic injection containing 60mg ketorolac provided similar analgesic efficacy and early functional recovery compared with 80mg triamcinolone acetonide. However, triamcinolone may benefit over ketorolac in early post-op knee flexion.

Objective: The high-definition 3D operating exoscope is a new tool for surgical visualization and magnification that was designed to replace the operating microscope. However, the paucity of studies that have prospectively compared the two systems has made it difficult to draw clear recommendations. The purpose of this study was to compare the operating exoscope and the operating microscope in first-time users in a pre-clinical setting. Methods: Twenty-eight consecutive medical students were prospectively enrolled and randomized in a crossover design. Each student performed four exercises that required basic microsurgical skills. A tailored questionnaire (Comparison Assessment Tool) was used to subjectively compare the two systems using a 5-point Likert scale. The time needed to perform each task was recorded. A post-intervention cross-sectional survey was conducted to assess the overall quality of the trial session. Results: The operating exoscope was preferred over the operating microscope by most of the students in all items of the Comparison Assessment Tool, particularly with regard to “focusing” and “image quality” (n = 25, 92.6%). A significant difference between groups was found in two exercises that were easier to perform with the operating exoscope. Most of the students considered the overall quality of the evaluation experience to be “very good” (n = 25, 92.6%). Conclusions: The exoscope allows first-time users to better perform basic microsurgical tasks in a simulated clinical scenario compared to the operating microscope. Further prospective comparative studies will be needed to validate our preliminary findings in an actual clinical scenario.

The pandemic (Covid-19) decreed by the World Health Organization on March 11, 2020, originating in China in 2019, has generated drastic changes for the world society, and so far is impacting negatively, and changing the quality of life of the entire population. Humanity has been facing an invisible disease and man needs to rethink consumption patterns, as well as the negative environmental impact generated by these patterns. To this end, we aimed to analyze the scientific productions on companies, accounting information and sustainability in the context of the pandemic (Covid-19). This study is classified as a descriptive, bibliographic and qualitative research, as it sought to identify information to highlight the socioeconomic and environmental impacts generated by the pandemic (Covid-19) in organizations.

A Medicina Veterinária nasceu quando o homem primitivo começou a domesticar o animal. Os primeiros métodos de diagnóstico, tratamento e prognóstico tiveram início por volta de 4.000 anos a.C., de acordo com o Papiro de Kahoun, descoberto no Egito, em 1890. Para alguns historiadores, esse é considerado o primeiro tratado de veterinária. Os códigos de Eshn Unna (1900 a.C.) e de Hammurabi (1700 a.C.), ambos da Babilônia, também já mencionavam a remuneração e as responsabilidades atribuídas aos “médicos dos animais”. Mas, somente em 1761 a Medicina Veterinária passou a ser uma profissão científica, por meio da criação da primeira Escola de Medicina Veterinária na França e no mundo, na cidade de Lyon. E desde essa época, esta fascinante profissão vem expandindo-se aceleradamente. Atualmente, existem mais de 50 atividades em que o médico veterinário pode atuar. Ou seja, o trabalho dos Médicos Veterinários vai muito além das clínicas e dos consultórios veterinários, destinados aos animais de companhia:, eles atuam em atividades ligadas à produção dos alimentos de origem animal que chegam à mesa do consumidor, têm papel fundamental na agropecuária brasileira, podem trabalhar como consultores, responsáveis técnicos, docentes e peritos criminais, judiciais e administrativos, exercem atividades em laboratórios para análise de solo, para análise da água e domissanitários – ou seja, saneantes destinados ao uso domiciliar, realizam pesquisas em alimentos, participam da produção de vacinas e de medicamentos de uso animal, entre outros. Este livro, conseguiu abranger conhecimentos científicos em diversas áreas da veterinária, contribuindo imensamente para o crescimento e reconhecimento cada vez maior da profissão. Acredito, que esta obra, nos seus diversos temas, irá apoiar ainda mais a ciência veterinária, contribuindo para o seu constante crescimento.
ANATOMIA ÓSSEA E MUSCULAR DA CINTURA PELVINA, ESTILOPÓDIO E ZEUGOPÓDIO DE CAIMAN CROCODILOS: PARTE I

A era Mesozoica, referida como era dos répteis, teve duração em média de 180 milhões de anos, a partir do Paleozoico, há 245 milhões de anos, até o começo do Cenozoico, há 66 milhões de anos. Neste período, os animais associados à ampla disseminação dos tetrápodes, foram os Archosauria, com destaque para os dinossauros e pterossauros. Uma vez dominantes no período mesozoico, os dinossauros foram subdivididos em duas ordens: Saurisquios, e Ornitísquios. Todos os ornitísquios possuem uma osteologia pelvina sinapomórfica para a classe. Os únicos remanescentes dos Archosauria são os aligátores, os crocodilos, e os gaviais (Gavialis gangeticus), que por sua vez, pertencem à ordem Crocodylia. Apesar destes animais apresentarem similaridades estruturais aos dinossauros bípedes, filogeneticamente, estão distanciados da árvore genealógica dos répteis. Em geral, não há tipicidade reptiliana em suas características anatômicas. Atualmente, há oito gêneros com 25 espécies de crocodilianos a nível mundial. No Brasil são encontradas seis espécies pertencentes à família Alligatoridae: Melanosuchus niger (jacaré-açú), Paleosuchus palpebrosus (jacaré paguá), Paleosuchus trigonatus (jacaré-coroa), Caiman crocodilus (jacarétinga), Caiman yacare (jacaré-do pantanal) e Caiman latirostris (jacaré-do-papo amarelo). Em relação ao padrão locomotor dos membros, anfíbios e lagartos assumem posturas em extensão gradual, enquanto os mamíferos e dinossauros mantém-se eretos, e os Crocodylia são capazes de assumir posições semieretas, além de ocasionais extensões graduais, e rastejantes.

Nos últimos anos, constatou-se o aumento no número de idosos, parcela da população mais sensível aos perigos relacionados aos agentes etiológicos de doenças alimentares. O estudo de suplementos voltados para esta fração populacional visa esclarecer os perigos aos quais idosos estão expostos, orientar o processamento tecnológico e resguardar a saúde do consumidor. Buscou-se identificar os microrganismos presentes e, consequentemente, a qualidade microbiológica de suplementos em pó para idosos.

As abelhas pertencem à ordem Hymenoptera que agrupa cerca de 20 mil espécies distribuídas pelo mundo, sendo 1.576 dessas espécies registradas no Brasil. O presente estudo objetivou caracterizar a comunidade de abelhas da Floresta Nacional do Tapirapé-Aquiri. A captura de abelhas ocorreu na área de implantação da Mina de Cobre do Projeto Salobo, realizadas em 2010 e 2011, em duas áreas distintas de Floresta Ombrófila Aberta de Submontana (Área de Influência 2 e Área Controle). Para a captura das abelhas foram utilizados os métodos de iscas odoríferas em armadilhas de garrafa e rede entomológica. Foram coletadas 4.863 abelhas, sendo 2.655 na Área Controle e 2.208 na Área de Influência 2, pertencentes a 102 espécies, 20 gêneros e 4 tribos distribuídas nas famílias Apidae e Halictidae, com destaque para espécie Partamona testacea (412). O gênero mais frequente foi o Euglossa, seguido do Trigona, Eulaema, Partamona e Tetragona. A realização de levantamentos padronizados nessa região, representa um significativo avanço no fechamento da lacuna de escassez de dados científicos para esta porção da Amazônia.

A ováriohisterectomia (OVH) é a cirurgia realizada com maior frequência em pequenos animais, sendo a esterilização eletiva sua indicação mais comum. Em felinos, têm sido realizados por laparotomia, laparoscopia ou laparoscopia híbrida. Neste estudo, avaliou-se 30 gatas, adultas, hígidas, sem raça definida, com peso entre 2 e 4,5 kg. Os animais foram distribuídos em três grupos. No primeiro grupo os animais foram submetidos a OVH por acesso laparoscópico; no segundo grupo o acesso foi laparoscópico híbrido e no terceiro grupo a OVH foi realizada pela técnica convencional (celiotomia mediana). Estes grupos foram avaliados com relação ao tempo cirúrgico e o tempo de procedimento, ao tamanho das incisões e às complicações durante e após a cirurgia. Também foram comparadas as alterações nas concentrações séricas de creatina quinase (CK) e aspartato aminotransferase (AST). Com relação ao tempo cirúrgico o segundo grupo apresentou tempo significativamente maior que os demais. Quanto ao tempo de procedimento operatório o terceiro grupo apresentou tempo menor. O tamanho de incisão foi maior no terceiro grupo. As complicações encontradas no trans-operatório foram enfisema subcutâneo (incidência maior no segundo grupo) e permanência dos cornos uterinos após secção do corpo uterino, com maior número de animais no terceiro grupo. A laparoscopia híbrida apresentou maior concentração de CK. Demais parâmetros não diferiram significativamente entre os acessos laparoscópicos e convencional. Concluiu-se que para o procedimento de OVH em felinos a cirurgia totalmente laparoscópica apresentou vantagens quando comparada a OVH híbrida e convencional, com relação às avaliações realizadas no trans e pós-operatório.

Inicialmente, diante do objeto em estudo, é necessário entender qual o real sentido e significado do conceito de Administração Pública. O verbo administrar significa gerir negócios públicos ou particulares, seguindo a lei e utilizando de forma adequada, bens pertencentes a outras pessoas, ou a coletividade. Administração Pública é a gestão de bens e interesses pertencentes à coletividade, que devem ser conservados e utilizados sempre seguindo os preceitos do Direito e da Moral, visando ao bem comum. Uma das principais finalidades da Administração Pública seria tutelar e proteger o bem comum, pertencente à população. O agente público que se desviar desse objetivo, estará contrariando a função para qual foi incumbido, devendo os atos viciados por ele praticados serem considerados nulos e desfeitos desde a origem.
A NÃO SUPERAÇÃO DA SÚMULA Nº347

O Ministro Alexandre de Moraes havia concedido, no ano de 2017, de maneira singular, a liminar, sob o fundamento de que o Tribunal de Contas da União não poderia exercer o controle difuso de constitucionalidade nos julgamentos de seus processos sob o argumento da vigência da Súmula nº 347. A tese sustentada pelo Ministro Relator é a de que, a partir da Carta Magna, apenas órgãos jurisdicionais podem declarar a inconstitucionalidade de leis e atos normativos, assim, seria inviável a manutenção do verbete da Súmula nº 347.
