Efectos marco, implicaturas por defecto y racionalidad
Authors: Caamaño María
Published: July 2022

Las variaciones en la forma en que los sujetos responden a las descripciones de un mismo asunto enmarcadas positiva o negativamente han sido objeto de atención por parte de la investigación en ciencias sociales, donde, sin embargo, una concepción insuficientemente desarrollada de la interpretación del discurso ha socavado las diferentes explicaciones ofrecidas. Los efectos marco suelen considerarse un signo de irracionalidad, ya que entrarían en conflicto con el "principio de extensionalidad", un supuesto habitual en la teoría de la elección racional, que establece que las diferentes formas de presentar el mismo conjunto de opciones posibles no deberían cambiar las elecciones de los sujetos con respecto a esas opciones. El presente artículo explora la vertiente semántico-pragmática de los efectos marco y ofrece una explicación de este fenómeno en términos de un efecto conjunto de las presuposiciones pragmáticas y las implicaturas por defecto. La explicación sugerida desafía la visión tradicional de los efectos marco como signos de irracionalidad, desplazando el foco de la controversia, de la racionalidad del juicio (o la decisión), a la racionalidad de la interpretación.

Authors: Ogunbanjo O. O. , Oladapo F. O. , Oladapo F. O.
Published: July 2022

This study profiled labile exogenous metals ubiquitous in the ecology of Ogun River induced by persistent anthropogenic activities along the riverbanks. The labile metals existing as metal-ions were trapped with a passive sampling technique of diffused gradients in thin films (DGT) subsequent upon which the metal-ions were carefully extracted and analyzed using the Atomic Absorption Spectroscopy (AAS). Nine labile metals (Pb, Cd, Ni, Cr, Co, Cu, Mn, Fe and Zn) were targeted in this study. The results of the study showed that mean values of labile Fe and Zn exceeded 3 µg/L whilst those of labile Pb, Cd and Mn occurred in the range of 1.41 and 1.88 µg/L in the river matrices. The mean values of labile Cr, Co, Ni and Cu occurred below 1.0 µg/L in the river matrices. The high industrial activities and population density along the Isheri, Ilo and Owo axes of the Ogun River accentuated the presence of labile Pb, Zn and Fe in the river matrices.

Authors: Abatyough M. T. , Ajibola V. O. , Agbaji E. B. , Yashim Z. I.
Published: July 2022

The reaction conditions for pyrolysis of corncobs was investigated for improved bio-oil yield. The corncobs were first demineralized to reduce inorganics composition using various solvents; nitric acid, acetic acid and water for a number of days. The effect of temperature, catalyst load and retention time were optimized using response surface methodology (RSM) of central composite design matrix (CCD). Three levels of the parameters were studied using face centered approach. The optimal bio-oil yield of 20 % was obtained at 6000C temperature, 7 wt. % catalyst load, and 3-hour retention time. A model equation was generated using the data obtained and the analysis of variance (ANOVA) showed the model to be significant with an R2 of 0.9505. From the statistical analysis, the predicted bio-oil yields were closely related to the experimental bio-oil yields indicating that the model was accurate to be used for design and optimization of bio-oil yield from pyrolysis of corn cobs.

U-Shaped Design of MIMO Antenna for 5G Applications
Authors: Harsha K. S. , Divya D.
Published: July 2022

Multiple input-multiple output, or MIMO, is a wireless communication antenna system that employs multiple antennas at both the source and the destination. MIMO improves radio frequency system capacity, which results in a more dependable connection and less congestion. A low profile directional radial antenna is called a microstrip antenna. These are easy and affordable. They can be applied to some different things, such as mobile, radio, wireless, satellite, missile, and air, space, and ground vehicles. The fifth generation (5G) technological standard for broadband cellular networks is now used in telecommunications. The main benefit of this network is that it has more bandwidth, which eventually results in faster download speeds of up to 10 gigabytes per second. The Microstrip Antenna, which satisfies specific parameters including physical size, low profile, and ease of fabrication, is the most crucial component to support 5G communication. A novel U-shaped MIMO antenna that can be used for dual-band applications is proposed in this project. The proposed antenna needs to be compact and have attributes like a good VSWR, gain, bandwidth, return loss, and directivity, among others.
Nuevas consideraciones sobre la tabla de San Miguel del Museo Diocesano de Arte Sacro de Orihuela
Authors: López Marcos Pablo
Published: July 2022

La tabla del San Miguel, actualmente conservada en el Museo Diocesano de Arte Sacro de Orihuela, representa uno de los principales ejemplos de pintura renacentista en España. De origen incierto, el cuadro fue localizado en 1906 por Tormo y Monzó en el colegio de santo Domingo de Orihuela, donde ocupaba un puesto de honor. El presente texto tiene la intención de realizar una necesaria revisión de la situación de la tabla, partiendo desde los conocimientos hasta ahora publicados y profundizando en las teorías planteadas por los diferentes historiadores a lo largo del tiempo. La propuesta de nuevas consideraciones sobre la pintura oriolana tiene como objetivo esclarecer su origen, así como presentar una novedosa propuesta atributiva legada a un ambiente pictórico que no había sido considerado hasta el momento, como era la pintura del centro-norte de Italia que alcanzará España en un segundo momento.
ORGANIZATOR VOLONTERSKE USLUGE
Authors:   University of Kragujevac, Faculty of Law, Brković Radoje
Published: July 2022

The question of the organization of volunteering plays a particularly important role, since the quality of the volunteer service provided and its realization depends directly on the method of organizing volunteer work. When it comes to the organization of volunteering, it is expected that the state bodies, as well as the organs of local self-governments, take active participation in this. This provides active support and encouragement of volunteer work by the state and state authorities, in accordance with the contemporary tendencies of revival and revitalization of volunteer work. Although volunteer work is primarily related to the activity of humanitarian work and work with particularly vulnerable categories of population, the tendency is that volunteering as a form of engaging people, different age and education structures is actualized in all areas of social life, as is the case with countries in the region, as well as Member States of the European Union.
POSTUPAK IZVANREDNE UPRAVE: INSOLVENCIJSKI MODEL KAO „TALAC“ KRIZE
Authors:   University of Rijeka, Faculty of Law, Bodul Dejan , Matić Ivo
Published: July 2022

The global crisis in recent years has resulted in an inconsistent economic policy of EU member states that ranged from the policy of proclaimed liberalism to the policy of ad hoc interventionism. It is the result of a mismatch between the capacity of the nation state and its existing obligations towards its citizens. Doctrinal analyses state that, therefore, states are trying to fulfil their expected function by implementing insolvency regulations aimed at rescuing infrastructure "losers" from liquidation bankruptcy while retaining those entities that are the backbone of national development policy. In this regard, this paper intends to analyse the model of Extraordinary Management Procedure defined by the Law on the Executive Administration Procedure in Companies of Systemic Importance for the Republic of Croatia. Due to the controversy that exists on the doctrinal plan related to the implementation as well as the application of the aforementioned regulations, a lot of questions have been opened, and there is no clear answer. However, it seems useful to try to detect some problems of positive regulation and offer possible solutions to the protection of creditors and debtors during the following systemic crises. For comparison and possible suggestions de lege ferenda for the Serbian legislator, these experiences are potentially important because a reform of the regulations (and even insolvency regulation) is underway, primarily by the process of harmonization of Serbian regulations with EU regulations. The complexity of the subject of research and the set tasks were conditioned by the choice of methods, so the methodology used in the research included the study of domestic and foreign literature, relevant legislation, as well as the analysis of domestic and foreign court practices. We certainly consider it important to point out that the space that we have here does not allow us for a detailed breakdown of this issue, so we are forced to limit ourselves, in the author's opinion, to some aspects of the new bankruptcy regulations.

Published: July 2022

The emergence of the world and civilization was accompanied by interpersonal disagreements, which turned into disputes. In the disputed parties, the party seeks to preserve and protect the rights and freedoms guaranteed by the state-legal order. On this path, they have different kinds of legal assistance, of which the best known is, but also the most controversial аdvocacy. Advocacy is as old as the state and law and is an essential element of a well-organized, progressive society, as well as a confirmation of a legal and democratic state. The way of organizing this independent and independent activity, as well as the tendency to change its functionality and role in the legal apparatus of the state are just some of the issues that will be addressed in the upcoming work.

The use of medicines implies a risk of damage to the patient. The danger of the use of a drug may be of a different nature, considering a chemical nature of the medical product, which also determines its pharmacological effect, thus disabling completely safe use of the drug. In fact, one should bear in mind the ambivalent effect of a drug which, besides therapeutic characteristic, has accompanying adverse effects on the health of the user, which is the risk one must count on. The institute of liability for damage (the responsible persons, the legal nature of the responsibility) is of particular importance for Serbian medical law, bearing in mind that it is not specifically regulated in the law. Further, this issue is complicated due to the fact that the implementation of the medical treatment involves a large number of persons: the doctor who prescribes the medicine, the drug manufacturer who issues the medicine, and the pharmacist who sells the drug. That is the reason why the liability for the damage using medicine, deserves special attention in the legal doctrine.

Published: July 2022

Hostel management system is an advanced system that makes organizing the affairs of the hostel quicker, simpler, and more efficient. The normal procedure of allocating hostels at Babcock University involves selecting the preferred hostel online via the UMIS (University management information system) portal while the procedure for selecting rooms involves students showing up physically in school with their evidence of school fees payment. Due to these, it is undeniable that it is extremely time-consuming with an unreliable method of storing relevant documents and requires a lot of human resources. This proposed hostel management system is a web application developed using C# programming language. This application includes a module that finds missing items, a module for hostel registration and also a module for giving feedback. In conclusion the model has made managing the affairs of the hostel easy.

Authors:   , Sitoe Heralda Juliana
Published: July 2022

Objetivou-se avaliar o consumo, a digestibilidade e o desempenho de ovinos alimentados com dietas à base de silagem de dois híbridos de sorgo. Foram usados 18 ovinos F1 Santa Inês × Dorper, não castrados, com idade entre quatro e seis meses e peso médio de 26,2 kg ± 3,9kg, em delineamento inteiramente casualizado, com dois tratamentos e nove repetições. Os tratamentos corresponderam às silagens do sorgo forrageiro AGX 213 (; Agroceres®, Brasil) e sorgo biomassa, híbrido Agri-002E (Biomatrix, Brasil) como fonte volumosa das dietas. As dietas experimentais consistiram de 600 g/kg de silagem e 400 g/kg de concentrado (base da matéria seca, MS) e foram isoprotéicas (160,0 g de proteína bruta (PB)/kg MS). O período experimental teve duração de 55 dias, com 14 dias de adaptação e 41 dias de coleta de amostras e dados. Observou-se maior (P≤0,052) consumo de MS, PB, carboidratos não fibrosos (CNF), nutrientes digestíveis totais (NDT) e de extrato etéreo (EE) para os animais alimentados com silagem de sorgo forrageiro, e maior (P=0,002) consumo de fibra insolúvel em detergente neutro indigestível (FDNi) para os alimentados com silagem de sorgo biomassa. Foram registradas maiores (P≤0,0465) digestibilidades da MS (P≤0,0465) e do EE (0,050), para a dieta contendo silagem de sorgo forrageiro. A digestibilidade dos demais nutrientes foi similar entre as dietas, com médias de 707,85; 384,4; 578,25 e 742,55 g/kg para as digestibilidades da PB, FDNcp, MO e CNF, respetivamente. A silagem de sorgo forrageiro proporcionou maior (P=0,0272) ganho médio diário de peso dos animais e maior eficiência alimentar (p=0,050). Conclui-se, que a dieta contendo silagem de sorgo forrageiro é mais indicada para alimentação de cordeiros confinados, por proporcionar maior consumo de nutrientes, bem como, maior ganho de peso dos animais.

Authors:   , Abe Fabiana Miuki Higa
Published: July 2022

O estudo foi realizado para avaliar o efeito da inclusão de carboidrases e suplementação de fitase em dietas para leitões na fase de creche sobre o no desempenho e viabilidade econômica das estratégias nutricionais. Foram utilizados 320 leitões, machos castrados e fêmeas, com peso inicial de 4,8 ± 0,7 kg. O delineamento experimental para disposição dos tratamentos foi o de blocos ao acaso, de acordo com o peso inicial dos animais, com 5 tratamentos (dietas experimentais), 8 repetições e 8 animais por unidade experimental representada pela baia. O período experimental foi dividido em três: pré-inicial – dos 20 aos 30 dias; inicial 1 – dos 31 aos 40 dias; e inicial 2 – dos 41 aos 61 dias de idade dos leitões. Em cada fase, as dietas experimentais consistiram em T1, dieta controle sem adição de enzimas exógenas; T2, dieta controle negativo com desvalorização de 0,14% de P disponível, 0,14% de Ca e 90 kcal de EM; T3, dieta T2 suplementada com 500 FTU de fitase e 100 g de carboidrase; T4, dieta T2 suplementada com 1000 FTU de fitase e 100 g de carboidrase; T5, dieta T2 suplementada com 1500 FTU de fitase e 100 g de carboidrase. Durante cada fase, foi avaliado o consumo diário de ração (CDR), ganho de peso diário (GPD) e conversão alimentar (CA). Os dados de desempenho foram analisados pelo modelo linear geral, via procedimento GLM do SAS, e as médias ajustadas foram comparadas pelo teste Tukey e os efeitos considerados significativos caso P < 0,05. A análise de viabilidade econômica foi realizada através da determinação do custo de ração em R$/kg de peso vivo ganho e o cálculo do índice de eficiência econômica. Na fase pré-inicial, a desvalorização de P, Ca e EM do T2 resultou na redução no GPD e piora na CA (p<0,01) se comparado ao T1, T3, T4 e T5. Na fase inicial I, animais T1 tiveram CRD superior aos animais T2 e similar aos tratamentos T3 a T5. Também, animais do grupo T1 tiveram GPD superior e melhor CA quando comparados aos tratamentos T2 ao T5. Na fase inicial II, o CRD não foi influenciado pelos tratamentos. Animais do grupo T1 tiveram CPD superior aos demais tratamentos (T2-T5) e melhor CA em relação aos tratamentos T2 e T3. Considerando o período total de avaliação, o CRD não foi influenciado pelos tratamentos. No entanto, animais T1 tiveram CRD superior aos animais T2 e similar aos tratamentos T3 a T5, e melhor CA quando comparados aos tratamentos T2 ao T5. Em termos de viabilidade econômica, o T1 obteve o melhor resultado quando comparado aos tratamentos T2 e T3. As dietas com inclusão de enzimas obtiveram melhores resultados em comparação a dieta desvalorizada sem enzimas. No entanto, a super dose de fitase não foi suficiente para promover a liberação de P e Ca necessários para melhorar o desempenho dos animais. Palavras-chave: Aditivos. Enzimas. Fósforo fítico.

Use of flow cytometry to quantify intracellular Leishmania sp.
Authors:   , Silva Adriana Carneiro da
Published: July 2022

The search for new methodologies that make the work in the search for new drugs more precise, agile, and with greater standardization is very important to the study of leishmaniasis. The technique most used to assess the leishmanicidal effect of a given drug in vitro, the slide count, despite being consolidated in the scientific environment, presents several difficulties in its execution, assessment, and results. In addition to being laborious, this technique takes time, both for the preparation of the material for analysis and for the counting itself. Based on this need, our research group proposes a new methodology based on nuclear labeling, using propidium iodide and flow cytometry to quantify the parasite load of Leishmania sp. in macrophages in vitro. Our results show that the fluorescence of infected samples increases as the infection rate increases. Using Pearson's Correlation analysis, it was possible to establish a correlation coefficient (Pearson r = 0.9473) that was positive, linear, and directly proportional to the variables fluorescence and infection rate. Thus, it is possible to infer a mathematical equation, through linear regression, to obtain an estimate of the number of parasites in each sample through the Relative Fluorescence Units (RFU) values. This new methodology opens space for the possibility of using this methodological resource in the in vitro quantification of Leishmania sp. in macrophages. Keywords: Flow cytometry. Leishmaniasis. Propidium iodide.
Desigualdades territoriais no acesso à água e esgoto nas periferias da Metrópole:
Authors: Rocha Andre
Published: July 2022

A expansão das áreas metropolitanas, em especial no Brasil, tem exigido reflexões sobre as condições de habitabilidade e vida nas cidades, em especial nas áreas periféricas, marcadas por profundas desigualdades na inacessibilidade de serviços, que revelam as contradições das condições gerais de produção nestas áreas. Um grande exemplo é acessibilidade aos serviços das redes técnicas de água e esgotamento sanitário, vistos como elementos primários e essenciais à dignidade humana. As desigualdades neste acesso são marcadas territorialmente e acabam por revelar diferenciações internas que somatizam os problemas das áreas periféricas.  Por isso, o presente artigo tem como objetivo discutir essa desigualdade, tomando como exemplo o caso de 5 municípios periférico do Rio de Janeiro, que fazem parte da região conhecida popularmente como Baixada Fluminense, marcados pelo paradoxo da inserção em uma das maiores bacias hidrográficas de abastecimento urbano do mundo e a condição de vulnerabilidade no acesso ao saneamento

Global overview of Leishmania virulence factors, and the role of GP63 in promastigotes
Authors: Alyasiri Ali Jawad , Qasim Waheeb Mohammed
Published: July 2022

Protozoa parasites of the genus Leishmania have a great ability to avoid damage in the hostile environments they encounter throughout their life cycle within the host’s body. Parasites have developed many virulence factors to ensure their persistence and replication within the host, and the first role of these factors is to attenuate the host’s defenses against them through innate and adaptive immunity, as evidence indicates that the determinants of parasite virulence are responsible for evading the host’s defenses, allowing these organisms to survive on Alive in the host’s hostile immune environment. Understanding the molecular details of how these pathogens persist with impunity under extreme conditions is beginning to begin. The fact that Leishmania parasites have adapted not only to survive but are likely to reproduce is due to the protection afforded by specialized molecules on the parasite’s cell surface. Although recent years have seen clear and significant progress in the research on Leishmania in different directions, many issues have yet to be clarified. The surface of all parasites, especially protozoa, usually undergoes pronounced changes during their life cycle. It is of particular interest in the case of protozoan parasites of the genus Leishmania whose surface is exposed to different and hostile environments within vertebrate and invertebrate organisms. Because of the importance that the cell surface of pathogenic parasites plays in their interaction with the host for survival, some efforts have been devoted to their characterization. This review aims to give an overview of the main virulence factors that contribute to parasite survival and survival. We have attempted to provide a brief picture of the factors that influence the interaction of the parasite in its host, further highlighting GP63 as a critical virulence factor affecting macrophage physiology as well as the functioning of the immune system.

Published: July 2022

Purpose: The increase in operations cost in Kenya has seen some hotels close while others lose guests. In addition, poor customer relationship management and the loss of accreditations issued early are thought to be a result of rising operating costs. The study sought to investigate the effects of cost-cutting strategies on guest satisfaction in hotels in the coast region, specifically Mombasa, Kilifi, and Kwale.

Methodology: To collect and analyze data for this study, a quantitative approach using survey design and stratified random sampling were used. A total of 394 questionnaires were distributed to various respondents from various strata across the levels in hotels in Kenya's coast region. Descriptive statistics and regression analysis were used in SPSS version 21 to analyze the data and produce percentages and frequencies to describe the data as well as determine the impact of cost-cutting strategies on guest satisfaction.

Findings: It was discovered that hotels in Kenya's coast region prioritized guest satisfaction and implemented a variety of strategies to improve and retain guest satisfaction. However, it was discovered that not all strategies contributed to increased guest satisfaction. The study discovered that water and energy conservation strategies had a positive effect on guest satisfaction in hotels in Kenya's coast region. Labor cost-cutting strategies, on the other hand, had a negative impact on hotel guest satisfaction. The relationship between labor cost cutting strategies and guest satisfaction is negative (r= - 0.116). There exist positive relationship between energy and water saving strategies and guest satisfaction (r= 0.09). From the model summary, it was established that variances in labor cost reduction strategies, energy and water conservation strategies accounted for 42.7% changes in guest satisfaction among hotels (R squared= 0.42).

Contribution to theory and practice: The study's findings are important for policymakers because they can help develop policies in the hospitality industry that can help hotels improve and maintain guest satisfaction. In addition, hoteliers can learn about the impact of cost-cutting strategies on their customers from the study findings.

The study aims to find out how fast-food consumption affects the overweight problem among young adults. A cross-sectional study was carried out on 100 young adults aged 15 to 29 years living in Kiriella village in Ratnapura District, Sri Lanka. Information regarding fast-food consumption level, occupation, height, weight, and other relevant facts were obtained using an online questionnaire. Both descriptive and inferential statistics were used to analyze the data. The overall fast-food consumption was 44% and 56% of males and females respectively. 17% of A/L students and 27% of university students consumed fast food at a high level. Overweight was detected among 19% of A/L students, 28% of university students, and 3% of employers. Being overweight was determined to be strongly associated with fast-food consumption. Overweight which was detected as 50% among young adults was statistically significant and highly associated with their occupation. Gender was not statistically associated with overweight. However, the study revealed that fast-food consumption among young adults is noticeably associated with overweight.

This paper presents a simple process of fabricating a superhydrophobic carbon steel surface with high water repellence and good corrosion resistance. The steel surface was covered by thin ZnO layers via various methods of sol-gel method, hydrothermal synthesis, and electrochemical deposition, then further functionalised with methyltrichlorosilane. Morphological features observed by a scanning electron microscope (SEM) show that ZnO layers are composed of micro/nanostructures. Furthermore, the chemical composition of these films has been analysed by an energy dispersive X-ray spectroscopy (EDX). An optimum experimental condition, based on the type of Zn deposition method, has been obtained to provide superhydrophobic properties with a water contact angle of 152 ± 2o. In a 3.5 wt% NaCl solution, the corrosion resistance properties of the superhydrophobic ZnO-coated steel are found to be very good with an anti-corrosion efficiency of 93.12%.

Potential innovators need to overcome many challenges. One such challenge is confirmation bias in decision-making. Human evolution has programmed the brain to act quickly in the face of a threat in the environment. In this way, thinking and (instantaneously) acting rationally is almost impossible for most people. This causes several negative effects on decision-making, notably cognitive biases. For example, an entrepreneur who wants to launch a new product on the market tends to convince herself/himself that her/his product is innovative, ignoring evidence to the contrary, this being a confirmation bias. An innovative analysis of the causes and consequences of the confirmation bias in innovation decision-making is the main goal of this article.

The main goal of modern second language (L2) pedagogy is to engender effective communication among its learners. Willingness to Communicate (WTC) has emerged as the most vibrant topic in L2 pedagogy, especially in the last two decades. A plethora of research on students’ views about their WTC has been conducted in a variety of contexts. However, research on teachers’ views about their students’ WTC in English is still in its infancy. Thus, this study investigated ESL teachers’ views about their undergraduates’ WTC in English inside the classroom. The cluster sampling technique was used to collect data from 80 ESL teachers from eight universities in Khyber Pakhtunkhwa province of Pakistan. The results revealed that the teachers viewed the undergraduates’ level of WTC as high in most classroom situations, such as during groups, during activities with the same and opposite gender, when given preparation time, seated in the middle of the class, and in front of the whole class. However, students showed a moderate level of WTC in situations such as sitting in front of the class and at the back of the class. A one-way ANOVA was performed to examine the differences between different classroom situations. The results showed significant differences in the teachers’ views about their students’ WTC in most classroom situations. Thus, the current study affirms that WTC is a dynamic variable that changes from situation to situation.

Nutrient recycling from biowaste is one of the sustainable approaches to managing waste. The aquaponic system is one of the nutrient recycling methods that can reduce water consumption and reuse the nutrient available in its ecosystem. The nutrient to fertilize the plant in aquaponic depends on the activities of microbes to convert the waste into the nutrient. To enhance the growth of the plants, some aquaponics systems still rely on chemical fertilizers. Kappaphycus alvarezii is one of the red seaweeds abundantly found in East Malaysia. After numerous processes such as carrageenan extraction, the biowaste derived from K. alvarezii still contains a nutrient that can be recycled. The present study explores the potential of K. alvarezii solid waste as fertilizer to grow Ocimum basilicum in an aquaponics system. In this study, the macro- and micronutrients in K. alvarezii solid waste were determined, and the prevalence of microbes in the aquaponics system was monitored using inductively coupled plasma-optical emission spectrometer (ICP-OES) and 16S metagenomic sequencing method, respectively. Based on the findings, the growth of O. basilicum supplemented with K. alvarezii biofertilizer was significantly higher than the negative control. For genetic expression study in O. basilicum, cinnamyl alcohol dehydrogenase (CAD), phenylalanine ammonia-lyase (PAL), and cytochrome p450 reductase (CPR) genes were upregulated. The O. basilicum is free from mycotoxin and heavy metals. Since K. alvarezii solid waste is rich with macro- and micronutrients, which are essential for plant growth and can enhance the growth of O. basilicum, K. alvarezii solid waste produced from bioethanol production could be a potential fertilizer.

The primary nasal canine transmissible venereal tumor (CTVT) is a rare disease that develops by the allografted transmission of neoplastic cells in the nasal cavity. The disease is uncommonly reported in free-roaming dogs, with the social behavior of excessive licking and vigorously sniffing the affected parts of the other dogs in an endemic population. Post-chemotherapeutic computed tomography (CT) scan features and correlation of vincristine sulfate with cellular phenotypes have been scarcely reported in previously available primary nasal CTVT studies. This study describes the radiographic, computed tomographic, and cellular phenotypic features in four dogs affected with stage-4 intranasal CTVTs. The post-chemotherapeutic features of the nasal cavity in fully recovered cases are also highlighted. All data were analyzed retrospectively. All four dogs had stage 4 modified Adam’s staging for nasal tumors due to the complete or partial lysis of the cribriform plate and lymphocytoid plasmacytoid (mixed) phenotype of the neoplastic cells based on the cellularity of cytological samples. All four dogs responded well to five cycles of vincristine sulfate and recovered completely. Two out of four dogs have follow-up scanning after chemotherapy. Based on the present study results, vincristine sulfate is still an effective monotherapy to achieve full recovery, although the number of cycles can vary, possibly depending on the expressed phenotype. Permanent loss of nasal turbinates is the sequelae of therapeutic chemotherapy. Prognosis is not correlated to the staging system but seems good with vincristine sulfate in mixed phenotype cases.

In this study, wireless power transfer using a transmitting horn antenna and receiving module is designed and analyzed. The receiving module comprises transmitting (horn) and receiving antennas, rectifier, and power management unit. The receiving antenna is used at a frequency of 2.45 GHz which seems to be the most efficient one. The integrated system being low in weight is suitable to be placed on any system having a battery with recharging characteristics. The compact system is designed and simulated using CST STUDIO. The receiving module is used for the conversion of microwave power to DC power for the easy charging of a Quadcopter. Drones always carry a minimal amount of payload and hence require a low weight power receiving system. The integration of 3 by 4 antenna array with the power management circuit makes it of minimal weight which is effective for UAVs. The distance taken into consideration is from 1 to 6m which works in relation to the power transmitted. Far-field transfer is designed and calculated but the method of improving the efficiency to a greater distance is still a concern of research.
