Clinoptilolite (E567), a natural zeolite, inclusion in heavy-pig diets: Effect on the productive performance and gaseous emissions during fattening and manure storage
Authors: Dinuccio Elio , Maffia Jacopo , Lazzaroni Carla , Airoldi Gianfranco , Balsari Paolo , Biagini Davide
Published: April 2022

Intensive pig rearing systems produce several air pollutant emissions, mainly associated with housing and slurry storage. Dietary strategies based on the use of feed additives can effectively mitigate such impacts. This work has been aimed at evaluating the effectiveness of dietary zeolites in mitigating ammonia (NH3), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) emissions from piggery and slurry storage on finishing pig farms. An experimental trial, in which three groups of approximately 500 pigs each were reared, has been carried out on a commercial pig farm. The three groups were fed the same diet, with the addition of 0 g/kg (Z0, control), 10 g/kg (Z1), and 20 g/kg (Z2) of micronized clinoptilolite (E567), respectively. The emissions from housing facilities and the live and slaughtering animal performances, were assessed. In addition, manure samples were collected during the rearing period to evaluate, at a laboratory scale, the NH3, CO2, CH4, and N2O emission potential during the subsequent slurry storage phase prior to land application. The results have shown that the addition of dietary zeolite can be considered a valid strategy to reduce gaseous emissions from pig houses without affecting animal performances or the system’s overall productivity. Treatment Z2 gave the best results and resulted in a 25% and 36% reduction of NH3 and CO2 equivalent emission fluxes, respectively, compared to those recorded for the control. The laboratory- scale experiment revealed no significant effect of dietary clinoptilolite inclusion on NH3 or the greenhouse gas emission potential during slurry storage.

Multiple sclerosis and venous angioplasty for chronic cerebrospinal venous insufficiency: a case control study with ten years follow-up with patients at their own control
Authors: Bavera Pietro Maria
Published: April 2022

Progressive Neurological Diseases (PND) and Chronic Cerebrospinal Venous Insufficiency (CCSVI) and Multiple Sclerosis (MS) have two terms in common: “progressive and chronic” and shortly mean that there is no definitive therapy, at the moment. The clinical aspects are built on symptoms, upon which the definition of “progression” is based and hence classified. Changement and worsening of symptoms, allow classification of the disease and adjustments are effectively an “up to date” of the disease itself. We here resume the ten-year survey of 482 Multiple Sclerosis (MS)-affected patients (314 females, 168 males; mean age =37.8), classified by their Neurology Physicians as Relapse-Remitting (RR), according to the Kurtzke Expanded Disability Status Scale (EDSS), monitoring the parallel presence of CCSVI with clinical MS progression. Results are present from two homogeneous Relapse-Remitting MS groups of patients divided as “treated and non-treated for CCSVI” with vein angioplasty (vPTA). Furthermore, a Patient’s self-classification based upon symptoms in presence of CCSVI, up to now never implemented, was developed on the basis of both clinical and Duplex vascular issues.

Authors: Jang Han Na , Jung Hye Seung
Published: April 2022

Not only mean blood glucose, but also ‘glycemic variability,’ the degree of fluctuation in blood glucose, has been suggested to contribute to diabetic complications. Glycemic variability can be expressed with various indices, such as standard deviation, coefficient of variation (CV), mean amplitude of glycemic excursion, etc.; however, standard indicators have not been established. Recently, CV was designated in cases of application of continuous glucose monitoring system according to international consensus. In this review, clinical implications of glycemic variability are dealt with respect to micro- and macrovascular complications of diabetes, and clinical evidence of new anti-diabetics are summarized about efficacy on the glycemic variability.
Blood Pressure Variability and Diabetes Mellitus
Authors: Jeong Chaiho , Sohn Tae-Seo
Published: April 2022

Increased blood pressure variability (BPV) has been found to significantly increase the risk of cardiovascular morbidity and mortality in the non-diabetic population. The prognostic importance of increased BPV for the development of micro- and macrovascular complications in type 2 diabetes has been investigated. Type 2 diabetes can increase BPV through different mechanisms, including increased arterial stiffness and autonomic dysfunction. Several studies in type 2 diabetic patients showed inconclusive results regarding all-cause mortality, microvascular complication, and extended major adverse cardiovascular events (MACE). However, some trials showed that BPV might be regarded as a potentially important therapeutic target in the management of type 2 diabetes regarding MACE. For now, the primary goal of antihypertensive treatment in patients with type 2 diabetes shall remain to controll mean blood pressure levels. However, when future studies show consistent results, BPV might be regarded as a therapeutic target in type 2 diabetic patients.

Authors: Lim Sung-Chul
Published: April 2022

The purpose of this study was to examine the effects of motivational interviewing (MI) training on diabetes educators’ counseling skills and self-efficacy. Diabetes educators were randomly allocated to the MI training group or control group. The experimental group was provided with a one-day course on MI. Pre-, post-, and follow-up (F/U) measurements were compared. Twenty-four diabetes educators participated in this study. Scores on the counseling skills post-test and F/U-test increased significantly compared to pre-test in the MI training group, as did scores on the helping skill self-efficacy post-test and F/U-test. Session management self-efficacy post-test scores also increased significantly compared to pre-test in the MI training group. There were no significant differences in pre-post and pre-F/U scores in the control group. Diabetes educator-patient communication is an important factor affecting the management of diabetes. MI training increases the counseling skills & self-efficacy of diabetes educators. Diabetes educators should use MI to facilitate patient health behavior changes in diabetes education.
Proving Ground Durability Test Schedule Development for Electrified Vehicle Drivelines Using Virtual Simulations
Authors: Mohamed Richard Phillip , Salvatori David , Ramakrishnan Venkat , Magistrali Stefano
Published: April 2022

A new method is presented for developing proving ground durability tests for electrified vehicle (xEV) drivetrains. For xEVs, the durability tests must be able to capture the added driveline torques due to regenerative braking, customer battery charge/recharge usage, and battery power degradation over time. In terms of xEV duty cycle test schedule development, using actual vehicle data from specific proving ground test events might prove to be costly and time consuming. Furthermore, newer electrified prototype vehicles might not be available for trackside testing while still undergoing the design stage. The new method presented here aims to reduce the complexities of xEV proving ground duty cycle development with the use of a high-fidelity vehicle dynamics simulation model for electrified powertrains. The xEV model uses a mixture of forward (to predict speeds, given torque demands) and inverse dynamics (to predict torques, given constant speed requirements) to predict driveline component torques and speeds. It is also robust enough to handle multiple xEV architectures. By first correlating the model with a similar existing vehicle test, or using data from dynamometer tests for newer electrified components, confidence is gained in the model’s fidelity. Afterwards, by using computed customer pseudo-damage requirements for electrified driveline components, the updated virtual model is utilized to develop new proving ground test events and schedules to match customer durability requirements. Finally, the model can then be used to predict xEV driveline loads on proving grounds through the use of virtual testing during early vehicle development stages before vehicle tests can occur.
Development of a CAE Modeling Technique for Heavy Duty Cargo Weight using a DFSS Methodology

Published: April 2022

Cargo box is one of the indispensable structures of a pickup truck which makes it capable of transporting heavy cargo weights. This heavy cargo weight plays an important role in durability performance of the box structure when subjected to road load inputs. Finite element representation for huge cargo weight is always challenging, especially in a linear model under dynamic proving ground road load durability analysis using a superposition approach. Any gap in virtual modeling technique can lead to absurd cargo box modes and hence durability results. With the existing computer aided engineering (CAE) approach, durability results could not correlate much with physical testing results. It was crucial to have the right and robust CAE modeling technique to represent the heavy cargo weight to provide the right torsional and cargo modes of the box structure and in turn good durability results.

As there are multiple variables owing to heavy cargo weight, Design for Six Sigma (DFSS) methodology was used to develop a robust CAE modeling technique. This project was defined with multiple key control factors considering geometrical and material properties of cargo along with the multiple ways to connect cargo ballast with the box floor bed. The manufacturing variability of box panels was considered as a noise factor. L18 Orthogonal Array matrix was chosen to optimize the variables based on factorial effects of signal to noise (S/N) ratio. Finally, the validation was done for the achieved optimum solutions using numerical tests.

This paper describes the DFSS project in detail, and emphasizes on how the DFSS approach could be very effective to predict the influential control factors and how the combination of these factors was utilized to find out the optimum solution. This paper also highlights how the optimized/proposed CAE modeling technique improves the accuracy of the cargo box modal and durability results.

Green Sea Turtle (Chelonia Mydas): a Historical Review With Relevance to Population Size in Sarawak
Authors: Hassan Ruhana , Yahya Nurhartini Kamalia
Published: March 2022

Green sea turtles (Chelonia mydas) are using selected Sarawak sandy beaches for nesting. Its small-scale conservation efforts have started since the 1950s. However, the success of the effort is still debatable. Moreover, public participation in the conservation effort is still at an infancy stage. This study involved analysing nesting data of green turtles of Sarawak Turtle Islands (STIs) in terms of numbers of turtle landing, eggs collected, eggs incubated, and eggs hatched for Sarawak’s green turtle population from 1949 to 2016 with addition of estimation of the egg-laying females and their remigration interval. There was a sharp decline in terms of number of turtle landings from 1949 to the 1970s. The exact cause of this pattern could only be confirmed from old articles of historical value due to limited information on the events happening during those 30 years period. From 1980 to 2016, the annual nesting trend of turtles on STIs shows irregular fluctuation pattern and remigration interval of every 3 to 4 years with internesting frequency of 3. Turtle eggs were harvested annually, with a 36-year average of 223,558 eggs per year. Detailed analysis for data 1980 to 2016 shows that the lowest percentage of eggs incubated was in 1981 (20.4 %) and starting from the year 1991, egg incubation at STIs reached between 90 to 100 percent. There is an upward trend of egg hatching rate for the past 36 years, especially from the 1990s to 2000s, with the latest seven years average of 60%. The results imply that conservation of green turtle in Sarawak have been successful at different levels. However, there is still a need for relevant state agencies to modify and step-up efforts related to conservation of green turtles in Sarawak especially in terms of male:female ratio of hatchlings from STI’s hatcheries.

Authors: Gavali Mr. P. B. , Patil Mr. Akshay
Published: April 2022

High productivity is the basic need of any manufacturing industry nowadays because of high quality product demand and cost efficiency. Turning is the basic operation in manufacturing and to optimize the process, the output parameters like material removal rate that is to be maximized and surface finish which is to be minimized, must be assessed at close look. The study shows the effect of input parameters (cutting speed, depth of cut and feed rate) on the parameters of the turning process. Three levels of each parameter are selected within the operating range and the experimental runs are performed according to Taguchi’s L-27 orthogonal array. The turning of EN9 specimen is carried out on CNC lathe. The material removal rate is found out by weight difference method and surface roughness is measured by 301 Mitutoyo surface roughness meter. After plotting the main effect charts and analyzing with ANOVA, it is found out that MRR is affected most by depth of cut and then feed rate. On the other hand, surface roughness is most affected by feed rate and then depth of cut. Cutting speed has statistically negligible effect on both the parameters. The study suggests optimum range of parameters that would give an efficient turning process.
Analysis of Existing Approaches for Information Sharing in Cooperative Intelligent Transport Systems '“ SENSORIS and V2X Messaging
Authors:   Technische Hochschule Ingolstadt, GERMANY, Festag Andreas ,   Fraunhofer Institute for Transportation and Infrastructure Systems IVI, GERMANY, Rui Song
Published: April 2022

Information sharing is essential for autonomous driving supported by communications and smart traffic driven by big data. It enables the acquisition of knowledge in cooperative intelligent transport systems (C-ITS), which ultimately increases the integrity and accuracy of road environmental data and thereby improves the efficiency, safety and comfort of the traffic system. Moreover, many cloud services and applications, such as self-healing HD Maps, demand massive information sharing by means of vehicle-to-X (V2X) communications. In this paper, we review two existing frameworks for information sharing in C-ITS, which are open, standardized and commonly accepted: SENSORIS primarily targets at data sharing with and among clouds, specifically for digital maps. V2X-Messaging focuses on road safety and traffic efficiency based on ad hoc communications among C-ITS-Stations (C-ITS-S), including vehicles, the roadside infrastructure and backends. Then, we analyze both frameworks considering various technical criteria and involved use cases. Finally, we propose a hybrid software architecture that combines both information sharing approaches and facilitates interworking between SENSORIS and V2X-Messaging in order to enhance C-ITS application.
Positioning Sensor System for Transmodular Mobility

Published: April 2022

Worldwide, regions are on the verge of collapse due to an ongoing urbanization and an increasing number of cars. To relieve overcrowded roads, future urban mobility has to become more flexible and more efficient. The idea of transmodular mobility is to change and share different transportation carriers within a higher-level transportation system. This enables and combines the efficient use of different carrier systems like railways, buses, ropeways or aircraft and increases passenger convenience. Practically, this would mean that different transportation carriers share the same kind of passenger cabins. For instance, a passenger cabin can perform as a bus to reach small and narrow streets and for particular tracks, it would transform into an urban ropeway to benefit from its higher passenger throughput. However, the critical part of this transformation is the coupling process. Therefore, reliable coupling interfaces are required which must be precisely aligned to perform a successful coupling procedure. In this regard, reliable sensor systems are required which can provide precise positioning data of the coupling interfaces for their counterparts. Conventionally, automotive sensors for range detection purposes either consist of radar or sonar-based systems. Automotive radars are known for a comparable large detection range and can cover up to hundreds of meters. However, the resolution is typically in the range of a few centimeters and even more. Sonar-based systems feature less detection range and are mostly used for short-range detection of obstacles in direct proximity to the sensor. Due to their high resolution and low production costs, they are used for a wide range of park assist systems. Nevertheless, what conventional radar and sonar-based sensor systems have in common is that they do not distinguish between particular obstacles without further signal processing. This means, objects around the sensor can be detected but cannot be identified. However, object identification can be achieved by more advanced systems like LIDAR, camera-based or radar-based imaging techniques. This, in turn, comes with an increasing amount of signal processing and production costs. This paper presents a new concept of a positioning sensor system for transmodular mobility without the need for complex image and signal processing capability. It is based on a sonar system approach, in which the transmitting nodes and receiving nodes are separated. Thereby, the transmitting node can serve as a reference point on the target object (e.g. passenger cabin) and the receiving node can be placed on the locating object (e.g. transportation carrier), respectively. In this regard, both objects are related to each other in a local reference system. The sensor system is extended by an auxiliary radio link for synchronization purposes. It can cover a range of more than 5 meters with a maximum positioning resolution in the millimeter range.

Objectives: To elucidate the involved culprit arteries and proportion of spontaneous arterial recanalization (SAR) in acute lateral wall myocardial infarction (ALWMI) patients in Pakistan.
Methodology: This cross-sectional study was conducted in the outpatient department (OPD) of a tertiary care cardiac center from February 2019 to July 2019. Patients meeting selection criteria of ALWMI were included. Key angiographic outcomes were recorded for each patient. Proportion of SAR in terms of involved culprit arteries was assessed.
Results: One hundred fifty two (152) patients were included, out of which 81% (124) were males. Mean age was 54.73 ± 11.03 years. Most (46.4%) of the study patients presented with single vessel disease. Overall, 89 (59%) patients showed SAR with settled ECG changes. Of them 73 (66%), 8 (33%) and 8 (47%) patients had diagonal artery involvement, 1st obtuse marginal artery involvement and ramus intermedius artery involvement respectively. Statistical significance (p=0.006) is observed for relationship of involved culprit arteries and SAR in ALWMI patients.
Conclusion: This cross-sectional study reports the proportion of arterial recanalization in terms of involved culprit arteries. Diagonal was the culprit artery (~ 73%) in most patients presented with ALWMI. SAR proportion is also highest in patients with diagonal artery involvement. This tendency of SAR was more in single vessel diseases patients compared to double vessel and triple vessel diseases patients.
Effect of NTT on Performance of AODV in a Linear AD HOC Network
Authors: SHARMA SAURABH , Alok Singh  , Rajneesh Kumar Srivastava
Published: April 2022

Wireless Ad Hoc Networks (WANETs) are predicted to be prevalent networks in coming future because of their infrastructure-less characteristics that result in self-organization, self-healing, and self-configuration of such networks. Routing means the process of selecting a path along which data can be transferred from source to destination that plays a significant role in the performance of ad hoc networks. There are many routing protocols developed for wireless ad hoc networks. One of such protocols, developed by C. E. Perkins, is Ad Hoc On-demand Distance Vector (AODV) routing protocol, which is a reactive routing protocol, AODV is used to establish route(s) between source node(s) and destination node(s) as and when routes are required. Performance of AODV routing protocol depends heavily on choice of values of a set of predefined attributes. One of such attributes of AODV is Node Traversal Time (NTT) which is supposed to play significant role in establishing route(s) between source node(s) and destination node(s). In this paper, we have investigated the performance of AODV in a linear wireless ad hoc network using different values of NTT using as well as without using Hello messages. The performance of the network has been measured using several metrics like Route Error Overhead, Routing Overhead, Normalized Routing Load, Average Hop Count, Total Number of Received Data Packets, Packet Delivery Ratio, Average End-to-End Delay and Throughput. It is observed that choice of value of NTT has a significant effect on establishment of route(s) between source node(s) and destination node(s) that eventually affects the performance of the linear wireless ad hoc network under consideration. The insights gained through this work could be useful in analysis of more realistic and complex networks.

O etanol anidro existente na gasolina deve obter a conformidade de 27% ± 1, em volume, segundo a ANP. Diante disso, o objetivo deste artigo foi analisar a taxa volumétrica de etanol anidro existente na gasolina tipo C de quinze estabelecimentos de Lavras (Minas Gerais) no triênio 2018-2020 e acompanhar o atendimento às especificações regulamentadas. Para a avaliação do teor deste álcool foi utilizado o método da proveta, regulamentado pela Norma Brasileira (NBR) 13992/2005. Os resultados mostraram a transição positiva no triênio 2018-2020, em que inicialmente 73,33% dos postos estavam fora da especificação, e,em 2020, 13,33% excederam a faixa permitida. Por fim, infere-se que houve uma melhoria na qualidade do combustível nos anos analisados.

A geopolítica nuclear descreve o conflito entre países combinando interesses energéticos e de materiais estratégicos. O surgimento da geopolítica nuclear brasileira pode ser historicamente situado em 1945, junto com a geopolítica nuclear mundial. Em ambas, o tório inicialmente exerceu papel central ao lado do urânio, até meados da década de 1970. Na década de 1990, houve uma retomada do interesse por reatores nucleares utilizando o ciclo do combustível tório, como alternativa às tecnologias dominantes que empregam o urânio. O conhecimento acumulado ao longo de 60 anos de pesquisas no Brasil sobre o ciclo do combustível tório possibilita considerar uma proposta para a adoção de um reator nuclear com tório como combustível. A dificuldade de inserção do tema nuclear na agenda política representa um desafio para a elaboração e implantação de políticas públicas para construção de um reator de tório no Brasil. O presente trabalho oferece um mapa tecnológico multicamadas para inserção de reatores de tório na agenda política nacional, destacando como contribuições: a descrição do processo sistemático de elaboração até a apresentação do modelo final de um mapa tecnológico, a proposta da inserção de reatores de tório no Programa Nuclear Brasileiro e a atualidade da geopolítica nuclear brasileira e mun-dial. Os autores concluem que o mapa tecnológico construído representa um ponto de partida aplicável para a inclusão do tema na agenda política nacional visando a construção e operação de novas plantas nucleares.

Estimar o preço de um ativo financeiro ou de produtos comercializáveis é uma tarefa complexa e que pressupõe a disponibilidade de uma quantidade razoável de amostras de dados. No ambiente de comercialização de energia elétrica, a projeção do preço da energia no mercado de curto prazo em base horária é essencial para a tomada de decisão dentro desse complexo mercado e as particularidades do setor elétrico brasileiro tornam essa tarefa ainda mais complexa do que em outros mercados. Devido ao comportamento estocástico de algumas variáveis, como a vazão afluente às usinas hidrelétricas e a correlação entre as variáveis que afetam a geração de eletricidade, as técnicas estatísticas tradicionais de previsão de séries temporais apresentam uma complexidade adicional, quando se procura prever diferentes horizontes de análise. Para enfrentar essas complexidades dos métodos tradicionais de previsão, neste estudo apresenta-se uma nova abordagem baseada em metodologia de Machine Learning para previsão de séries temporais aplicadas no processo de previsão do PLD. A Base de Aprendizado do modelo é obtida a partir de informações públicas dos modelos oficiais do setor: NEWAVE, DECOMP e DESSEM. A aplicação da metodologia para casos práticos, utilizando-se de backtest com informações reais do setor elétrico brasileiro, demonstra que a linha de pesquisa é promissora, à medida que a aderência das projeções aos valores realizados é significativa.

O desenvolvimento de novas tecnologias para geração de energia fotovoltaica permite aos consumidores gerar a sua própria energia, quando antes dependiam exclusivamente de uma empresa distribuidora de energia elétrica para tal. Com o “barateamento” dos equipamentos disponíveis, os consumidores têm se tornado cada vez menos dependentes das concessionárias de energia elétrica, haja vista que podem, durante uma parcela do dia, gerar sua própria eletricidade e ainda entregar a energia elétrica excedente para a empresa distribuidora, recebendo o abate proporcional pela eletricidade produzida em sua conta. Contudo, essa operação de remessa excedente está sendo alvo de projetos de lei que visam a cobrança de impostos do consumidor. O objetivo do artigo é demonstrar que a cobrança é ilegal pela ausência do fato gerador autorizador da incidência do Imposto sobre Circulação de Mercadorias e Prestação de Serviços de Transporte Interestadual, Intermunicipal e de Comunicação (ICMS) sobre a Tarifa de Uso do Sistema de Distribuição (TUSD). Para tanto, a metodologia utilizada foi a pesquisa bibliográfica.
Clausius, a entropia e a seta do tempo

2022 traz à memória eventos importantes, que merecem ser lembrados. No Brasil tivemos há cem anos a Semana de Arte Moderna, que promoveu a liberdade de criação, valorizando uma nacionalidade plural e inovadora. Nesse mesmo ano a Revolta dos 18 do Forte de Copacabana marcou o início do fim da República Velha. E duzentos anos atrás, tivemos a Independência do Brasil, hoje contada de distintas maneiras, mas sempre relevantes em nossa história. Também temos efemérides menos lembradas, mas não menos importantes. Em 2 de janeiro de 1822, em Köslin (atual Koszalin, Polônia), na Pomerânia prussiana, nasceu Rudolf Clausius, um dos fundadores da Termodinâmica, ciência essencial para os estudos energéticos. Em 1844 ele se diplomou em matemática e física na Universidade de Berlim, e em 1848 obteve seu doutorado na Universidade de Halle. Foi professor em diversas instituições, como a Universidade de Berlim, a ETH Zürich, a Universidade de Würzburg e finalmente a Universidade de Bonn, onde ficou por vários anos até seu falecimento em 1888, com amplo reconhecimento internacional por suas contribuições para os fundamentos da Termodinâmica, da Teoria Cinética dos Gases e da Eletrodinâmica. Nessas breves notas vamos rever a evolução e o impacto dos trabalhos de Clausius.
How Does International Crude Price Affect China’s Carbon Emission?
Authors: Chen Qiaoling
Published: April 2022

Abstract

This study extends the standard STIRPAT model by introducing an energy price factor and uses the extended STIRPAT model to examine the effect of international crude oil prices on China’s carbon emission, This paper applies Ridge regression to conduct empirical analysis. The study finds that changes in international crude prices have a significantly positive impact on China’s carbon emission. A 1 percent increase in international crude oil price leads to a 0.12 percent increase in China’s carbon emission This finding remains unchanged even after a set of control variables are included in the analysis and survives all the rigidity tests.

Keywords: Crude price, China, Carbon emission.
A Tentative View on the Invariance of Theory of Relativity

This paper aims at studying the premises presupposed by classical mechanics and relativity by proposing a new concept of higher dimensional space to show that the distance traveled by light in space is not objectively the same for different frames of reference, as contemporary physicists such as Newton and Einstein have always understood, but is consistent for any frame of reference!
