Educational Technologies for Hybrid Learning Contexts: A Grid of 12 Technological Communication Tools
Authors: Manciaracina Andrea Giuseppe
Published: December 2021

The mission of the university goes beyond contributing to society with the results of its research and innovation. Its scope is prompting and supporting young people to gain new knowledge while encouraging them to consider/include forms of social engagement. Then, it is crucial for teachers to engage students in the learning process. Students use technology to communicate; thus, they are more likely and comfortable to participate in a technology-driven environment. This purpose could be pursued through the correct choice of educational technologies within the learning environments. Communication technologies have the potential to engage learners while also providing motivation and support for both teaching and learning. This paper focuses on the definition of educational technologies and on the description of a grid of 12 technologies that were chosen based on the research activities undertaken in doctoral research at the Politecnico di Milano. Subsequently, the technologies are classified through different mappings and methodologies to produce a description showing advantages, disadvantages, and contexts of use. Finally, it analyses the technologies from the point of view of 2 learning contexts, on-site and online, to help create new hybrid learning processes.

Published: December 2021

Introduction: We aimed to compare the rate of postoperative infection and drug-resistant organism (DRO) before and during the COVID-19 pandemic in urology departments.
Methods: A retrospective cohort study was carried out. Data from all elective surgical procedures carried out in two urology departments between April and June 2018 and the homologous period in 2020 were collected. Main outcomes were the number of postoperative infections during the pandemic, and the number of DROs. Sample size was calculated based on a 50% relative reduction of infections during the pandemic. Variables were compared by Chi-squared test, and multivariable logistic regression was used to estimate predictors.
Results: A total of 698 patients undergoing elective surgery were included. The postoperative infection rate during the pre-pandemic period was of 14.1% compared to 12.1% during the pandemic (p=0.494). DROs were lower during the pandemic (92.3% vs. 52.4%, p=0.002). The pandemic period was the main predictor for reduced multi-drug-resistant isolates, with an odds ratio of 0.10 (p=0.010, 95% confidence interval 0.016–0.57).
Conclusions: Postoperative infection rates were not significantly reduced during the COVID-19 pandemic, despite the adoption of enhanced infection preventive measures. There was, however, a decrease in the rate of DROs during this period, suggesting a secondary benefit to enhanced infection prevention practices adopted during the COVID-19 era.
Associations between body mass index and bladder cancer survival: Is the obesity paradox short-lived?
Authors: Arthuso Fernanda , Fairey Adrian S. , Boule Normand G. , Courneya Kerry S.
Published: December 2021

Introduction: We investigated the associations of pre-surgical body mass index (BMI) with bladder cancer outcomes in patients treated with radical cystectomy.
Methods: We retrospectively analyzed data from 488 bladder cancer patients treated with radical cystectomy between 1994 and 2007 and followed up until 2016. Cox regression with step function (time-segment analysis) was conducted for overall survival because the proportional hazard assumption was violated.
Results: Of 488 bladder cancer patients, 155 (31.8%) were normal weight, 186 (38.1%) were overweight, and 147 (30.1%) were obese. During the median followup of 59.5 months, 363 (74.4%) patients died, including 197 (40.4%) from bladder cancer. In adjusted Cox regression analyses, BMI was not significantly associated with bladder cancer-specific survival for overweight (hazard ratio [HR] 0.79, 95% confidence interval [CI] 0.57–1.10, p=0.16) or obese (HR 0.76, 95% CI 0.52–1.09, p=0.13) patients. In the Cox regression with step function for overall survival, the time interaction was significant overall (p=0.020) and specifically for overweight patients (p=0.006). In the time-segment model, the HR for overweight during the first 63 months was 0.66 (95% CI 0.49–0.90, p=0.008), whereas it was 1.41 (95% CI 0.89–2.23, p=0.14) after 63 months. Although not statistically significant, a similar pattern was observed for obese patients.
Conclusions: Our findings suggest that overweight and obese bladder cancer patients had better outcomes within the first five years after radical cystectomy; however, there were no differences in longer-term survival. These data suggest that the obesity paradox in bladder cancer patients treated with radical cystectomy may be short-lived.
Culinary Properties of Raw Versus Conventional Soy Sauce during Tuna Preparation
Authors: Ando Mami , Obata Akio , Mok Wen Jye , Kitao Satoshi
Published: December 2021

Soy sauce is a traditional Japanese seasoning made from fermented soybeans. As global demand grows, identifying novel soy sauce applications and benefits must become a priority. While conventional soy sauce undergoes heat-sterilization, filter-sterilization produces a lighter-colored (raw) soy sauce with preserved mold enzyme activities. As the impact of raw soy sauce during food (especially seafood) preparation remains unstudied, the present study compared the differential impact of raw and conventional soy sauce on tuna culinary properties. First, soy sauce color and protease activity were assessed. Next, tuna was marinated in soy sauce and non-alcoholic mirin for 0, 10, 35, or 60 min. Finally, marinated tuna properties (mass, salt content, surface salt penetration, color, rupture load, surface wetness, and protein content) were objectively assessed, and subjective sensory evaluation (appearance, aroma, wetness, softness, saltiness, umami, and overall taste) was performed by a blinded panel. Findings confirmed the lighter color of and the preservation of protease activity in raw soy sauce. Raw soy sauce significantly enhanced surface tenderization, salt penetration, and wetness, while both soy sauces increased surface firmness via salt-induced dehydration. Respondents significantly preferred the appearance and saltiness level of raw soy sauce-marinated tuna, and the umami and overall taste of tuna marinated in raw soy sauce for 60 min. The findings of this study, to our knowledge, demonstrate for the first time the potential culinary superiority of raw soy sauce in certain applications, and support future research to further define such applications.

De impact van Laval anno 2021

De auteur neemt in deze bijdrage het Europese arrest Laval uit 2007 onder de loep. Het arrest Laval had een wezenlijke impact op Nederland als zogenoemd hogelonenland. Inmiddels zijn veertien jaar verstreken en zijn de Handhavingsrichtlijn en de herziene Detacheringsrichtlijn aangenomen en geïmplementeerd. Wat betekenen deze richtlijnen voor de impact van Laval? Hebben de nieuwe richtlijnen het arrest Laval naar de geschiedenisboeken verwezen of doolt de geest nog steeds rond? Het zal blijken dat Laval anno 2021 de gemoederen nog steeds bezighoudt.

Overpeinzingen omtrent de vakbond als ondernemersorganisatie en de regulering van de positie van de zzp’er

Vakbonden fungeren bij het behartigen van belangen van zzp’ers als ondernemersorganisaties. De enorme aanwas van zzp’ers compliceert daarmee ons systeem van arbeidsvoorwaardenvorming. De zzp’ers vallen in het krachtenveld van de sociale partners vaak tussen wal en schip. Het zou daarom juist zijn als de belangenbehartigers van zzp’ers losstaan van de sociale partners. Via de toetreding van zzp’ers tot besloten netwerken kunnen zzp’ers mededingingsrechtelijke beperkingen aan tariefafspraken ontgaan. Op soortgelijke wijze kunnen zzp’ers premielasten ontlopen die het SER-akkoord van juni 2021 voor zzp’ers op tafel legt. In beide gevallen speelt de vraag hoe men op heldere wijze de zzp’er kan afbakenen ten opzichte van andere ondernemers.

Enfoque AICLE y enseñanza del español en la educación superior británica: perspectivas del profesorado de ELE
Authors: Floriano Ramos Carmen , Fuertes Gutiérrez Mara
Published: December 2021

En la educación superior en Reino Unido, en los planes de estudio donde se enseña español, se distingue entre asignaturas denominadas de lengua —donde se aprende el idioma— y las denominadas “de contenido” —que tratan la historia, la política o la literatura en los países donde se habla español y se imparten en inglés—. Este artículo se apoya en el análisis temático de entrevistas a profesores universitarios de ELE en Reino Unido para explorar si el empleo del enfoque AICLE (Aprendizaje integrado de Contenido y Lenguas Extranjeras) puede facilitar la colaboración entre docentes de ambos tipos de asignaturas.

Location of liver lacerations resulting from deceleration injuries and a proposal for their classification
Authors: Arkuszewski Piotr
Published: December 2021

Aim: The aim of the study was to verify during forensic autopsies the occurrence of liver lacerations resulting from deceleration traumas in the locations reported in professional literature, and also to check whether they are located near the left coronary ligament and its extension, i.e. the left triangular liver ligament.

  Methods: The liver injuries were assessed on the base of cases of forensic autopsies, performed at the Department of Forensic Medicine of the Medical University of Lodz from 1st September 2011 to 15th April 2014. In order to analyze the collected data, descriptive methods and statistical inference methods were used.

 Results: Three types of liver rupture turned out to be characteristic and statistically significant: 1 – on the diaphragmatic surface of the right lobe between its two sectors; 2 – within the left lobe to the right (in segment IV) or to the left (in segment III) of the falciform ligament; 3 – located near the left coronary ligament (in segment II).

 Conclusion: Typical location of liver lacerations after deceleration trauma, i.e. the right triangular ligament and falciform ligament, are confirmed in the analysed autopsy material. The place not previously described in the literature, which should be regarded as a characteristic location of a liver rupture after deceleration trauma is the diaphragmatic surface of segment II of the left lobe.

Noise Attenuation of a Duct-resonator System Using Coupled Helmholtz Resonator - Thin Flexible Structures
Authors: Prasetiyo Iwan , Desendra Gradi , Anwar Khoerul , Agusta Mohammad Kemal
Published: December 2021

Several studies have been devoted to increasing the attenuation performance of the Helmholtz resonator (HR). One way is by periodic coupling of HRs in a ducting system. In this study, we propose a different approach, where a membrane (or a thin flexible structure in general) is added to the air cavity of a periodic HR array in order to further enhance the attenuation by utilizing the resonance effect of the membrane. It is expected that three attenuation mechanisms will exist in the system that can enhance the overall attenuation, i.e. the resonance mechanism of the HR, the Bragg reflection of the periodic system, and the resonance mechanism of the membrane or thin flexible structure. This study found that the proposed system yields two adjacent attenuation peaks, related to the HR and the membrane respectively. Moreover, extension of the attenuation bandwidth was also observed as a result of the periodic arrangement of HRs. With the same HR parameters, the peak attenuation by the membrane is tunable by changing its material properties. However, such a system does not always produce a wider attenuation bandwidth; the resonance bandwidths of both mechanisms must overlap.

Published: December 2021

This research examined thermal comfort in  church buildings in Indonesia by making a comparison between three different Indonesian climatic regions using three different research models. A static model, an adaptation study model and a CFD simulation were used to find the similarities and differences between the results generated from determining thermal comfort in church buildings in the three regions. The comparison revealed that church buildings had different PMV scores at each measuring point that were inversely proportional to the subjects’ response on thermal comfort inside the buildings, i.e. points adjoining with openings affect a low PMV score and a high perceived thermal sensation, and vice versa. The CFD simulation showed that changing the conditions of the openings affects air velocity and flow into the building, which influences the subjects’ thermal comfort response inside the churches.
The Role of Crop Protection in Sustainable Potato (Solanum tuberosum L.) Production to Alleviate Global Starvation Problem: An Overview
Authors: Ahmadu Tijjani , Abdullahi Adamu , Ahmad Khairulmazmi
Published: December 2021

Among food crops in terms of consumption, potato ranks fourth, most important and valuable crop worldwide in terms of production and area harvested after maize, wheat and rice. In the coming years, potato production must keep pace with global population expansion nutritiously and sustainably which can partially be achieved by reducing the yield losses caused by the destructive pest and disease activities to the crop. The challenge of 70–80% total microbial crop yield loss posed by pathogens must be addressed for sustainable potato production in order to properly alleviate the global starvation problem. Potato as a food security crop can help to achieve the four food security requirements: food availability, quality, accessibility and stability. Health benefits of potato have shown the presence of phytochemicals as well as resistant starch which serve as anticancer and antidiabetic. The role of potato in the global food security should not be over emphasized, hence in this chapter we want to give an overview on the global hunger and food security at present, and the role played by potato as a food security crop. In addition, potato yield losses caused by pests and diseases especially phytopathogens, their etiology and the role of crop protection in sustainable potato production to alleviate global starvation problem will be discussed.

Authors: Lei Bin , Li Wengui , Tang Zhuo , Yang Fuzhi
Published: December 2021

The application of recycled compound concrete made of demolished concrete lumps (DCLs) and fresh normal concrete in pier foundation can effectively improve the utilization efficiency of construction waste resources. In this study, two prefabricated pier foundations based on recycled compound concrete (dimension of Ø800 × 2500 mm and Ø1000 × 2500 mm) and two cast-in-place pier foundations based on ordinary concrete (dimension of Ø800 × 2500 mm and Ø1000 × 2500 mm) were tested. Special attention was devoted to the load-settlement curve characteristics of the precast pier foundation of compound concrete, the load transfer law of the pier-soil system, the soil pressure distribution at the bottom of the pier, and the failure mode. The results showed that the Q-S curve of precast concrete pier foundation made of recycled compound concrete is slow deformation at loading, which is consistent with that of cast-in-place concrete pier foundation. The load transfer theory of pier-soil system is established, and its accuracy is verified by experimental analysis. The precast foundation of recycled compound concrete is the same as the cast-in-place foundation of ordinary concrete. The failure form of prefabricated pier foundation made of recycled compound concrete was a local shear failure, while the failure form of ordinary concrete cast-in-place pier foundation was piercing-type shear failure. The feasibility of relevant theoretical methods for calculating the vertical ultimate bearing capacity is examined.
Transparent Vacuum Insulation Panels
Authors: Katsura Takao
Published: December 2021

New, low-cost transparent vacuum insulation panels (TVIPs) using structured cores for the windows of existing buildings are proposed. The TVIP is produced by inserting the structured core, the low-emissivity film, and the adsorbent into the transparent gas barrier envelopes. In this chapter, the authors introduce the outlines, the design and thermal analysis method, the performance evaluation (test) method. Firstly, five spacers, namely peek, modified peek, mesh, silica aerogel, and frame, are selected as the structured core. The effective thermal conductivity of TVIPs with five different spacers is evaluated at different pressure levels by applying numerical calculation. The result indicated that TVIPs with frame and mesh spacers accomplish better insulation performance, with a center-of-panel apparent thermal conductivity of 7.0 × 10−3 W/m K at a pressure of 1 Pa. The apparent thermal conductivity is the same as the value obtained by the simultaneous evacuation thermal conductivity measurement applying the heat flux meter method. Furthermore, using a frame-type TVIP with a total thickness of 3 mm attached to an existing window as a curtain decreases the space heat loss by approximately 69.5%, whereas the light transparency decreases to 75%.
An Overview of Pancreatic Neuroendocrine Tumors
Authors: Sharma Neha , Sharma Deepti
Published: December 2021

Pancreatic neuroendocrine tumors are a group of endocrine tumors that constitute 7% of all pancreatic neoplasms. They can be benign or malignant. Their presentation can vary from slow growing, non infiltrative, indolent masses to rapidly progressing, highly aggressive, metastasizing tumors. In the past, there was paucity of scientific data available about the diagnosis and treatment strategy of these neoplasms but in recent years, ongoing research has inferred much data regarding classification, prognostic stratification and therapy of pancreatic neuroendocrine tumors. In this chapter we will discuss epidemiology, clinical presentation and classification, diagnosis and management of these tumors. We will also deliberate about the latest developments in treatment of pancreatic neuroendocrine tumors with focus on recent studies done on this topic.
Solanum tuberosum Yield for Selected Countries
Authors: Dominick Waryoba Fulgence
Published: December 2021

This chapter, aimed at analyzing potato yield among selected countries, has seven sections. The panel analysis of potato production and productivity has shown significant differences among countries. The main panel analysis of the random and fixed effect model indicates a negative influence of land size on yield and a positive influence on production. However, using multilevel mixed effect model, some country specific estimates deviate from main model results. In yield and output equations, the influence of land is positive for some countries and negative for others. Improvement of potato productivity is vital for hunger relief and starvation reduction. Even though, area specific analysis can bring in many determinants of potato production and productivity. A detailed analysis can give the right direction for policy makers in their effort to reduce hunger and starvation as well as improve the living standards of people.

This chapter of this book shows that the mastery of some modern techniques is needed by the ship’s crew who work in a management to build a modern ship, in accordance with the theme of this project, namely modern ship engineering, design and operations. The main problem is how the management leaders of this modern ship project can apply transformational leadership style through work-life balance and employee engagement to the ship’s crew to make their work effectiveness improved. In carrying out the ship building which takes a quite long time, do the employees can be mutually engaged and can pay equal attention to the work in this project and the work at home? This study uses quantitative method with Structural Equation Modeling. This modern ship building uses some terminologies or variables of human resources such as transformational leadership style, work-life balance, and employee engagement which, based on the research done, directly and positively affect employee’s work effectiveness. The key findings of this study indicate that there is a specific model on employee engagement and crew work effectiveness that is very appropriate to be applied to modern ships related to engineering, design and operations.
For an Agonistic Element in Realist Legitimacy
Authors: Westphal Manon ,   Department of Philosophy, Florida State University
Published: December 2021

The article shows that an uncritical view of domination is a weakness of current accounts of realist legitimacy and it argues that an agonistic supplement can help overcome that weakness. Two accounts of realist legitimacy are discussed: the moral minimum account and the acceptance account. In each case, certain modifications of the argument are needed to establish a distance from moralism, but these modifications create an indifference to domination. The incorporation of an agonistic principle into realist legitimacy can solve this problem. The agonistic case for effective possibilities for contestation endows realist legitimacy with a critical stance towards arrangements that are unresponsive to criticism on the part of those who are subject to them without, however, introducing a moralist argument.
The Effect of Rapid Initiation Versus Delayed Initiation of Antibiotics in Pediatric Patients With Sepsis
Authors: Cowart Mallory C. , Heath Travis S. , Shipman Andrakeia
Published: December 2021

OBJECTIVE

The purpose of this study was to determine if administration of antibiotics within 1 hour of meeting sepsis criteria improved patient outcomes versus antibiotics administered greater than 1 hour after meeting sepsis criteria in pediatric patients. The Surviving Sepsis Campaign's international guidelines recommend appropriate antimicrobial therapy be administered within 1 hour of recognition of severe sepsis or septic shock. Data regarding outcomes in pediatric patients with sepsis regarding antibiotic timing are currently limited.

METHODS

This was a retrospective chart review of 69 pediatric patients admitted between July 1, 2013, and June 30, 2016, with a diagnosis of sepsis.

RESULTS

The primary outcome of in-hospital mortality was 7.1% in the within 1 hour group versus 14.6% in the greater than 1 hour group (p = 0.3399). Median hospital length of stay was significantly shorter in the within 1 hour group (15.4 versus 39.2 days, p = 0.0022). Median intensive care unit length of stay was also significantly shorter in the within 1 hour group (3.1 versus 33.6 days, p = 0.0191). There were no differences between groups for pediatric intensive care unit admission, end organ dysfunction, time to intubation, or time on the ventilator.

CONCLUSIONS

Pediatric patients who receive antimicrobial therapy within 1 hour of meeting sepsis criteria had improved hospital and intensive care unit length of stay. This study supports the Surviving Sepsis Guidelines recommendation to administer antibiotics within 1 hour in pediatric patients with sepsis or septic shock.

OBJECTIVE

Prophylaxis with posaconazole (PP) is effective in the prevention of invasive fungal infections in immunocompromised adult patients. However, evaluation of its effectiveness and safety in children is limited. The aim of the study was to describe the use of posaconazole as antifungal prophylaxis in children.

METHODS

We reviewed the medical records of immunocompromised patients younger than 13 years with hematologic diseases and post hematopoietic stem cell transplant (HSCT) who received antifungal PP at the Instituto Nacional de Salud del Niño San Borja (INSN-SB) in Lima, Peru, from January 2014 to December 2018.

RESULTS

Fifty-six courses of PP were identified in 47 patients with a median age of 7.5 years (IQR, 4–10), 51.6% (n = 24) of whom were female. The main underlying medical conditions were aplastic anemia (n = 19, 33.9%), acute lymphoblastic leukemia (n = 18, 32.1%), acute myeloid leukemia (n = 14, 25.0%), and 34.1% had undergone HSCT. The median dose of posaconazole was 13.62 mg/kg/day (IQR, 12.0–16.8), and the median duration of PP was 24 days (IQR, 16–82). Gastrointestinal symptoms included abdominal pain (17.9%), nausea (16.1%), diarrhea (7.1%), and vomiting (3.6%). Elevated alanine aminotransferase and aspartate aminotransferase levels were observed in 9/35 patients (25.7%) and 10/51 (19.6%) patients, respectively. Five cases of breakthrough fungal infection were identified (8.9%).

CONCLUSIONS

Patients younger than 13 years who received PP showed an increase in transaminase values, and the development of breakthrough fungal infections.

Published: December 2021

Teriparatide is a human parathyroid hormone analog approved for the treatment of osteoporosis in adult patients. Its use for hypocalcemia and hypoparathyroidism in the pediatric population is described through case reports and small case series; however, larger studies that demonstrate long-term efficacy and safety are limited. At our institution, a 4-month-old premature (gestational age: 32 weeks) infant with multiple congenital anomalies, functional athymia, and severe hypoparathyroidism and receiving calcitriol, vitamin D, and calcium carbonate supplementation was initiated on subcutaneous injection of teriparatide. During the course of treatment, her calcium carbonate, vitamin D, and calcitriol supplementation requirements substantially decreased. Teriparatide effectively increased serum ionized calcium concentrations and decreased serum phosphorus concentrations in the present case-study over a 6-month period. Teriparatide was well tolerated, and no evidence of hypercalcemia was observed throughout treatment.
Educators' perceptions regarding the inclusion of experts of various profiles into the team for inclusive education
Authors: Jeremić Biljana , Milenović Živorad
Published: December 2021

The past decade has witnessed the expansion of educators' competencies and their larger concern for children with developmental delays, i.e. inclusive education. The inclusion of developmentally delayed children into education is determined by the following: early detection of developmental conditions, timely intervention, an individualized education plan (IEP) and its practical application. The IEP is developed and implemented by the inclusive education team. The team members responsible for the development of the IEP for children with developmental delays in regular preschool education are: parents or caregivers, teachers and educators, early childhood professionals, personal assistants for developmentally delayed children, special education teachers or dialectologists, pedagogical assistants and other professionals. The goal of this research was to determine educators' opinion about the necessity of an early intervention as well as about the application of the IEP and the involvement of professional support in inclusive kindergarten programmes and practice. The sample was comprised of 70 early childhood educators with experience in teaching children with developmental delays. The research results showed that the participants were predominantly inclined towards the involvement of a music pedagogue into inclusive kindergarten education (51of them or 71%). Therefore, this paper analyses the possibilities of supporting children with developmental delays through music teaching classes.

The knowledge of the contents of organic compounds in aquatic ecosystems is of great importance,  since the dissolved organic matter represents a dynamic component in the interaction between geospheres. The objective of this study was to evaluate the levels of carbon, nitrogen, and carbon-to-nitrogen ratio in the marginal sediments and the carbon content in the waters along the Paraopeba river basin (MG). The samples were collected in five locations (Jeceaba, Brumadinho, Fortuna de Minas, Florestal, and Três Marias) corresponding to the high, medium, and low river segments. The carbon content was determined by the Walkley & Black method and the nitrogen content by the Kjeldahl method. The carbon content ranges from 4.75 to 5.97 g kg-1. Nitrogen ranged from 0.73 to 1.08 g kg-1. Finally, the carbon-to-nitrogen ratio varied from 5.15 to 21.25. The carbon content in the water samples ranged from 0 to 0.25 g L-1. As the values ​​of dissolved organic carbon were very low or even zero, the nitrogen content and the carbon-to-nitrogen ratio were not determined. There was a negative and a positive correlation with the aluminum content (r = -0.70 and r = 0.74, respectively) indicating possible contamination by heavy metals. Therefore, the levels of carbon, nitrogen, and the carbon-to-nitrogen ratio were sensitive indicators of changes in the aquatic ecosystem.

O objetivo do estudo foi avaliar as propriedades físicas e mecânicas de painéis aglomerados, confeccionados com partículas provenientes de resíduos do processamento mecânico da madeira de Schizolobium amazonicum Huber ex. Ducke (Paricá), tendo como aglutinante o adesivo de silicato de sódio. O delineamento utilizado foi o inteiramente casualizado, com 12 tratamentos e quatro repetições, totalizando 48 painéis. Os ensaios foram realizados de acordo com as normas ABNT/NBR 14810-3(2002) e ANSI/A-208.1(1999). As médias foram comparadas pelo teste Tukey para o coeficiente de esbeltez das partículas e pelo teste de Scott-Knott para as propriedades físicas e mecânicas, adotando-se 5% de significância para ambos (p≤0,05). Além disso, foi verificada a correlação da massa específica com os demais ensaios utilizando-se os coeficientes de Pearson, Kendall e Spearman. Concluiu-se que as propriedades dos painéis foram influenciadas pelo teor de adesivo, taxa de compactação e tipo de partícula derivada do resíduo lenhoso utilizado. De forma geral, os painéis confeccionados com partículas de cavacos, provenientes do resíduo rolo-resto, com maior teor de adesivo e maior taxa de compactação foram os que melhor atenderam aos requisitos tecnológicos exigidos pelas normas. A massa específica mostrou-se um importante índice de qualidade na avaliação dos painéis, devido à sua forte correlação com algumas propriedades físicas e mecânicas. O adesivo de silicato de sódio poderá ser uma alternativa promissora na confecção de painéis de madeira do tipo aglomerado, principalmente em locais internos onde houver restrições quanto ao uso de resinas à base de formaldeído.

O município de Taperoá localiza-se na região central do Estado da Paraíba, Mesorregião Borborema e Microrregião do Cariri Ocidental. O município está incluído na área geográfica de abrangência do semiárido do Brasil, tendo como critérios o índice pluviométrico, o índice de aridez e o risco a seca. Esta pesquisa está centrada no estudo da degradação ambiental no município de Taperoá - Paraíba, levando em consideração os limites geográficos que fica em torno da sub-bacia do rio, sendo ao norte, Areia de Baraúna, Salgadinho e Assunção, ao leste, Santo André e São José dos Cordeiros, ao sul, São José dos Cordeiros e Livramento, e ao oeste, Cacimbas e Passagem. Foram utilizados recursos disponíveis através das técnicas de geoprocessamento. O objetivo geral da pesquisa é analisar os níveis de degradação a partir de um estudo espaço temporal da cobertura vegetal, degradação das terras, além das vulnerabilidades da região, sendo elas social, econômica, tecnológica, ambiental e de susceptibilidade as estiagens. Para atender tais objetivos, foram realizados estudos comparativos dos anos de 1990 e 2015, dentro dos limites geográficos apresentados. Os resultados em relação aos níveis de degradação das terras, houve redução nos níveis de degradação baixa e moderado baixa (6,4 km2; 72,0 km2), o que apresenta uma redução nas áreas mais preservadas da região. No entanto, o nível degradação moderada teve aumento significativo (116 km2), este avanço no processo de degradação é consequência do desmatamento para diversos fins.

Este trabalho procurou avaliar a viabilidade técnica do uso do resíduo de açaí como estabilizante de um solo granular. Para isto, foram estudadas misturas de solos constituídas por percentagens de 0%, 10% e 20% de resíduo de açaí, em termos de massa seca total da mistura. Caracterizou-se o material “in natura” e suas composições alusivo às propriedades geotécnicas (granulometria, limite de liquidez, plasticidade e compactação) e de resistência mecânica, Índice de Suporte Califórnia (CBR) e resistência à compressão não confinada (RCNC). Os resultados indicaram que houve significativa melhora nas propriedades do solo regional quando aditivado pelo resíduo de açaí, do ponto de vista físico e mecânico, com ênfase para amostra com adição de 20% de resíduo.

Dentro do contexto de riscos e catástrofes naturais, tão presente no atual cenário brasileiro, este trabalho propõe uma avaliação mecanicista sobre os escoamentos de fluidos em planos inclinados (canais, encostas, corredores de drenagem, vertedouros de barragens, entre outros). O fenômeno roll wave (ondas de rolo, regime pulsante), caracterizado por sua configuração periódica e com frentes de onda que se deslocam com elevada velocidade na superfície livre, pode vir ocasionalmente surgir nestes escoamentos, caso condições suficientes sejam atingidas. Sua presença pode comprometer a integridade das estruturas civis e ainda potencializar os danos advindos de catástrofes desta natureza. Este trabalho avalia analítica e numericamente a formação destas ondas em escoamentos de fluidos newtonianos e não-newtonianos. O objetivo principal atingido neste artigo foi verificar a validade dos desenvolvimentos teóricos-analíticos em função dos resultados numéricos do simulador. No âmbito numérico, método de volumes finitos foi empregado, utilizando o software FLUENT (equações completas). Além disso, o modelo analítico utilizado, já estabelecido para corridas de lama de natureza viscoplástica (não-newtoniana) foi obtido a partir da manipulação das equações de Cauchy, com o modelo reológico de Herschel-Bulkley inserido na parte viscosa do tensor de tensões, promediadas na vertical. Um estudo comparativo entre os métodos foi desenvolvido, alcançando boa concordância entre os mesmos.

O presente estudo teve como objetivo elaborar curvas de permanência para estimar a disponibilidade hídrica na Microrregião do Alto Pantanal Mato-grossense. A referida microrregião é formada pelos municípios Barão de Melgaço, Cáceres, Curvelândia e Poconé, estando inserida na Região Hidrográfica do Paraguai, sendo drenada por importantes cursos d’água, tais como o Rio Paraguai, Rio Cuiabá e Rio São Lourenço, dentre outros tributários. Os dados utilizados foram referentes às séries históricas de vazões diárias durante um período superior a 30 anos, variando entre os anos 1960 e 2019, e que pertencem ao banco de dados da Agência Nacional de Águas e Saneamento Básico (ANA), Sistema Nacional de Informações sobre Recursos Hídricos (SNIRH). Também, foram consultadas as bases cartográficas da região para obter os arquivos com formato para dados geoespaciais em forma de vetor, disponíveis no portal do Instituto Brasileiro de Geografia e Estatística (IBGE). Os dados referentes às vazões foram organizados em planilhas Excel e os procedimentos gráficos e analíticos para a construção das curvas foram realizados com auxílio do programa R. Concluiu-se que as curvas de permanência elaboradas nesta pesquisa foram adequadas, precisas e confiáveis para avaliar a disponibilidade hídrica dos principais rios na microrregião do Alto Pantanal Mato-grossense, bem como estimar a vazão, em função da frequência de duração. Ao longo da série histórica analisada, as estações que apresentaram a maior e a menor vazão de permanência foram, respectivamente, a Pousada Taiamã (Rio Cuiabá) e Perto de Poconé (Rio Bento Gomes). Ressalta-se que a disponibilidade hídrica mais estável foi observada na estação Pousada Taiamã. A metodologia aplicada apresentou-se como excelente ferramenta para verificar os limites de vazão diária e diagnosticar o estado dos cursos d’água na região, em relação ao uso e ocupação do solo, auxiliando no planejamento e distribuição racional dos recursos hídricos.
