MATERAS INTELIGENTES; UNA APROXIMACIÓN A LA AGRICULTURA EN PEQUEÑA ESCALA PARA USO DOMÉSTICO
Authors: Chaparro Preciado Javier Alberto , Criado Sanguino Alejandro
Published: October 2022

Hambre cero es uno de los objetivos de desarrollo sostenible, y según la Organización de Las Naciones Unidas (ONU), 500 millones de pequeñas granjas en todo el mundo, la mayoría aún con producción de secano, proporcionan hasta el 80 por ciento de los alimentos que se consumen en gran parte del mundo en desarrollo. En Colombia, no estamos ajenos a una realidad similar si miramos los pequeños productores de la zona centro del país por citar un ejemplo. Se ha identificado que en los hogares de estratos bajos se tienen espacios desaprovechados como lo son terrazas y patios traseros, espacios que se pueden usar para instalar pequeños cultivos automatizados que produzcan la cantidad necesaria de cosecha para suplir un porcentaje de la dieta alimentaria de una familia. Con el propósito de atender este problema, el Semillero de Agroingeniería de la Escuela Colombiana de Ingeniería Julio Garavito, está trabajando en el desarrollo de pequeños sistemas electrónicos que tengan la capacidad de cultivar autónomamente diferentes vegetales, principalmente hortalizas, e incorporen adicionalmente nuevas tecnologías como la inteligencia artificial. Se seleccionó este tipo de productos dada su importancia para la alimentación y el hecho que se aprovechan hojas, frutos, tallos, raíces y flores incluso. Actualmente está en desarrollo el primer prototipo hecho a partir de una matera, con un ambiente aislado mediante un encerramiento de acrílico transparente, asistido con un sistema electrónico de control de variables ambientales y de terreno (temperatura, humedad, y ph). La temperatura se controla mediante un flujo continuo que se calienta con una resistencia eléctrica. También está en diseño el control de pH, el sistema de registro y vigilancia con imágenes, y el controlador central que atenderá el proceso completo a partir de la experiencia tomada de expertos y las condiciones agroecológicas del cultivo; esta información será depositada en sistemas de aprendizaje supervisado. El semillero lo conforman estudiantes de las carreras de ingeniería electrónica y mecánica que desarrollan proyectos con alcance de curso y que utilizan en las asignaturas de electrónica digital, electrónica análoga, control, señales y diseño principalmente.
What Determines the Success of Housing Mobility Programs?
Authors: Aliprantis Dionissi , Martin Hal , Tauber Kristen N.
Published: October 2022

This paper studies how design features influence the success of Housing Mobility Programs (HMPs) in reducing racial segregation. Targeting neighborhoods based on previous residents' outcomes does not allow for targeting race-specific outcomes, generates uncertainty when targeting income-specific outcomes, and generates bias in ranking neighborhoods' effects. Moreover, targeting opportunity bargains based on previous residents' outcomes selects tracts with large disagreements in current and previous residents' outcomes, with such disagreements predicted by sorting since 1990. HMP success is aided by the ability to port vouchers across jurisdictions, access to cars, and relaxing supply constraints, perhaps by targeting lower-ranked neighborhoods.

Authors: Chuiko Sergey Mikhailovich , Chuiko Olena Viktorivna , Shevtsova Kateryna Sergeyevna
Published: October 2022

The study of differential-algebraic boundary value problems was initiated in the works of K. Weierstrass, N. N. Luzin and F. R. Gantmacher. Systematic study of differential-algebraic boundary value problems is devoted to the work of S. Campbell, Yu. E. Boyarintsev, V. F. Chistyakov, A. M. Samoilenko, M. O. Perestyuk, V. P. Yakovets, O. A. Boichuk, A. Ilchmann and T. Reis. The study of the differential-algebraic boundary value problems is associated with numerous applications of such problems in the theory of nonlinear oscillations, in mechanics, biology, radio engineering, theory of control, theory of motion stability. At the same time, the study of differential algebraic boundary value problems is closely related to the study of pulse boundary value problems for differential equations, initiated M. O. Bogolybov, A. D. Myshkis, A. M. Samoilenko, M. O. Perestyk and O. A. Boichuk. Consequently, the actual problem is the transfer of the results obtained in the articles by S. Campbell, A. M. Samoilenko, M. O. Perestyuk and O. A. Boichuk on a pulse linear boundary value problems for differential-algebraic equations, in particular finding the necessary and sufficient conditions for the existence of the desired solutions, and also the construction of the Green’s operator of the Cauchy problem and the generalized Green operator of a pulse linear boundary value problem for a differential-algebraic equation. In this article we found the conditions of the existence and constructive scheme for finding the solutions of the linear Noetherian differential-algebraic boundary value problem for a differential-algebraic equation with singular impulse action. The proposed scheme of the research of the linear differential-algebraic boundary value problem for a differential-algebraic equation with impulse action in the critical case in this article can be transferred to the linear differential-algebraic boundary value problem for a differential-algebraic equation with singular impulse action. The above scheme of the analysis of the seminonlinear differential-algebraic boundary value problems with impulse action generalizes the results of S. Campbell, A. M. Samoilenko, M. O. Perestyuk and O. A. Boichuk and can be used for proving the solvability and constructing solutions of weakly nonlinear boundary value problems with singular impulse action in the critical and noncritical cases.

Published: October 2022

O presente artigo tem como tema de investigação os direitos humanos das mulheres com ênfase nos direitos das mulheres brasileiras. Os direitos humanos são resultado de uma construção histórica e já são significativos os avanços em termos da legislação relacionada às questões de gênero, o que motivou o interesse na pesquisa. O estudo tem como objetivo analisar os direitos das mulheres em documentos nacionais e internacionais e para tanto foi realizada uma pesquisa com abordagem qualitativa, mediante análise de: declarações, convenções, conferências, planos, estatutos, leis e políticas públicas. O estudo se apoia nos argumentos teóricos de Michel Foucault (1988), com base nos estudos de gênero de Judith Butler (2015), e das contribuições de Simone de Beauvoir (1980). A partir do estudo, foram encontrados 33 documentos, datados entre o período de 1789 a 2015, os quais evidenciam que a luta pelos direitos das mulheres foi intensa no aparato legal. No entanto, há muito para ser conquistado em termos de respeito à dignidade da pessoa humana, diante da complexidade interseccional, considerando a raça, a nacionalidade, a etnia, o gênero, a classe social, a região, a cultura, a religião, a orientação sexual, a identidade de gênero, a geração e a deficiência. Questiona-se a não materialidade de muitas políticas de direitos humanos, evidenciando a necessidade de superação do estigma, das violências, das discriminações, das desigualdades, das condições de exclusão social e de vulnerabilidades que marcam o cotidiano de milhares de mulheres brasileiras.

Published: October 2022

Background: The goal of this study was to clinically evaluate the effect of propolis gel in different polymeric systems as an adjunct to non-surgical therapy in the management of periodontitis patients. Methods: A total of 30 patients with stage III grade B periodontitis were divided into the following three groups: group I patients, who received propolis in a chitosan polymer gel with non-surgical therapy, group II patients, who received propolis in a polyox polymer gel with non-surgical therapy, and group III patients who served as a control treated with non-surgical therapy only. Clinical parameters were assessed at baseline, one month, and three months. Results: At three months, the mean gingival index (GI) of groups I and II was the same (0.6 ±0.52), and there was no change in the mean GI in group III. There was a reduction in the mean probing depth (PD) in group I (4.80 ±0.63) and group II (4.90 ±0.74) at the end of the study. The greatest percent gain in clinical attachment level (CAL) was noted in group II (17.26 ±6.71) followed by group I (5.93 ±9.87), whereas the least percent decrease was noted in group III (3.67 ±7.77). Conclusion: The adjunctive use of propolis in a polyox polymer with non-surgical therapy demonstrated superior clinical results over the use of propolis in a chitosan polymer in periodontitis patients.

Self-reflection has become a necessary skill to achieve the goal students set for themselves to be successful in pre-sea training. It helps students to improve their actions in critical situations, primarily when supported by religious practices. This study aimed to identify items that represent self-reflection as a religious factor for success in pre-sea training. A three-round Delphi approach was adopted in which ten experts were selected who met the necessary condition to participate in the study. Data were analyzed quantitatively using SPSS version 23 for median and IQR. The study found that self-reflection can be implemented through meditation and self-evaluation, the act of repentance, and returning to the source of religion. However, the experts felt that isolation is unsuitable for them as a ship's crew. They are advised to find other methods of meditation and self-assessment, such as self-contemplation. Students should return to the sources of religion, including the Quran and Sunnah, by reading books and online references and also seek the help of knowledgeable and pious people. However, experts pointed out how difficult it is for a Muslim to reach out to this pious person when he is the only Muslim on board. This study has developed 18 practices for students to implement self-reflection in the form of meditation and self-contemplation.

This article discussed the historiography of oil history presented in this review article. This article aimed to demonstrate that oil historians are continually conversing with one another through their publications, even if it is not always visible. This historiographical perspective was supposed to provide a valuable framework for understanding this debate. This article used descriptive analysis in analyzing data to examine major disputes in oil history and how interpretations of those debates have influenced the trajectory of oil history and diplomatic and economic events. The Prize, a famous work by Daniel Yergin, focused on the article's debate. The goal was to examine historical events or topics in oil history from many angles, drawing on several sources that have affected historians' contributions to the field. According to the article, Oil has always been linked to a quest for money and power. The global economy, the result of conflicts, and the political landscape of states were altered by this battle. This study showed that a never-ending attempt to secure Oil, as long as it is vital to human civilization, would eventually lead to wars and conflicts.

Authors: Park So Yeon , Han Min Jeong , Heo Jun Ho , Kim Sun Jun
Published: October 2022

Purpose: This study aimed to establish the medical evidence of abuse by comparing the clinical differences between children with shaken baby syndrome (SBS) who had no signs of trauma and traumatic brain injury (TBI). Methods: Children aged <5 years with intracranial hemorrhage (ICH) were divided into SBS group and TBI group, which was developed because of intentional or accidental trauma including physical violence. We investigated clinical characteristics, ICH and brain injury patterns, funduscopic examinations, and the legal consequences for guardians. Results: Compared to TBI, children with SBS had a higher incidence of neurological symptoms, including seizures (80.0% vs. 15.4%, P=0.001) and mental changes (73.3% vs. 32.5%, P=0.003); they also had a longer time to hospitalization (SBS, 21.8±30.4 hours; TBI, 9.5±21.3 hours; P=0.046). The rate of bilateral ICH was significantly higher in the SBS group (73.3% vs. 19.0%, P=0.001). In the TBI group, the incidence of epidural hemorrhage (EDH) and subdural hemorrhage was equal (42.3%), but EDH was not seen in the SBS group. Multistage ICH (58.3%) and diffusion-limiting lesions (75.0%) were common in SBS, with high mortality and neurological sequelae (86.7%). Nevertheless, only a few guardians (13.3%) were separated from the victim and only one person (6.7%) who confessed to abuse was detained. Conclusion: Children with SBS who have never been affected to external physical forces can have multistage and bilateral ICH with severe brain damage, which is clinically different from TBI. Our data suggest that adequate protection and active legal actions are required in order to protect children who had sufficient characteristics of SBS.

Published: October 2022

The flow rate at which the instantaneous maximum flow is recorded throughout the year is called the Annual Maximum Flow (AMF). These flow rates often cause disasters such as floods. Snow melts and extreme precipitation associated with temperature fluctuations are the two most important factors that occurred flooding. The deluge that follows kills people and destroys property in communities and agricultural lands. As a result, it's critical to predict the flow that causes flooding and take appropriate precautions to limit the damage. The prediction of the probability of a flood event in advance is very important for the safety of life and property of large masses and agricultural lands. Early warning systems, disaster management plans and minimizing these losses are among the important goals of the country's administration. This study was used in five Current Observation Stations (COS) located in Yeşilırmak Basin in Turkey. By using 8 input data including geographical location, altitude and area information of these stations, AMF data were tried to be estimated for each COS. A total of 240 input data was used in the study. The data period covers the years 1964-2012. Unfortunately, AMF values cannot be monitored for all 5 stations used after 2012. Therefore, the data period was stopped in 2012. In this study, Multilayer Artificial Neural Networks (MANN), Generalized Artificial Neural Networks (GANN), Radial Based Artificial Neural Networks (RBANN) and Multiple Linear Regulation (MLR) methods were used. Input data sets were made into 4 packets and these packages were used respectively in both training and testing stages. In these packages, the AMF data measured for the 5 stations mentioned above between 1965 and 2012 were divided into 4 and used by creating 25% (test) and 75% (training) packages. Root Means Square Error (RMSE), Mean Absolute Error (MAE) and correlation coefficient (R) were used as the comparison criteria. The results are as follow; MANN (RMSE = 119.118, MAE = 93.213, R = 0.808), and RBANN (RMSE = 111.559, MAE = 81.114, R = 0.900). These results show that AMF can be predicted with artificial intelligence techniques and can be used as an alternative method.

Bu çalışmada şerit döküm yöntemi ile imal edilen katı oksit yakıt pili (KOYP) elektrolit tabakaları metal bir elek ile birlikte farklı izostatik pres basınçları (10-60 MPa) altında preslenerek elektrolit üzerinde yüzey desenleri oluşturulmuştur. İzostatik pres basıncının etkileri; profilometre, performans, empedans ve mikroskop analizleri ile incelenmiştir. Elektrokimyasal ölçümler desenli elektrolite sahip bütün hücrelerin referans hücreden daha yüksek bir performans ortaya koyduğunu göstermiştir. Gerçekleştirilen analizler hücre performansındaki iyileşmenin desenleme ile artan elektrolit-elektrot arayüzey alanlarının yanı sıra lokal olarak azalan elektrolit kalınlığının da bir sonucu olduğunu ortaya çıkarmıştır. 0,373 W/cm2 ile en yüksek performansı ise 30 MPa basınçta preslenen desenli elektrolite sahip hücre sergilemiştir. Referans hücre için bu değer 0,320 W/cm2 olarak ölçülmüştür. Daha yüksek pres basınçlarında ise artan desen derinliğine bağlı olarak özellikle katot bölgesinde elektrolite kadar uzanan çatlaklar tespit edilmiştir. Bu çatlaklar, arayüzey alanındaki artışla artması beklenen elektrokimyasal reaksiyon bölgelerindeki iyileşmeyi sınırlayarak performans kayıplarına neden olmuştur.

Published: October 2022

Dual antiplatelet therapy (DAPT) using of acetylsalicylic acid and antagonists of platelet’s P2Y12 receptors is included in standards for treatment of patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI). Clopidogrel, prasugrel, and ticagrelor are the P2Y12 receptor inhibitors used as a component of DAPT. The aim of this review is to determine the most effective and the safest P2Y12 receptor inhibitor for treating patients with an invasive treatment strategy of ACS.

The TRITON study compared clopidogrel and pragugrel efficacy and safety had demonstrated a significantly higher efficiency in reducing the risk of reaching the primary endpoint (including cardiovascular death, myocardial infarction and stroke) for prasugrel, but at the same time, the prasugrel group was reliably recorded higher rate of major bleeding.

Comparison of the efficacy and safety of clopidogrel and ticagrelor was carried out in the PLATO study, where ticagrelor was shown to be more effective in reducing cardiovascular deaths and myocardial infarction, while the safety of the drugs was comparable.

A subsequent ISAR-REACT 5 study proved higher efficacy of prasugrel compared to ticagrelor in reducing the risk of reaching a primary endpoint with comparable safety to the major bleeding risk.

Baseline data represents that the most effective drug among P2Y12 receptor inhibitors as a component of DAPT for patients with an invasive treatment strategy is prasugrel, and the safest is clopidogrel, which can be considered in elderly patients.

Published: October 2022

The routine execution of a fine-needle aspiration puncture biopsy is the most informative method for the preoperative diagnosis of thyroid neoplasms, as well as a promising base for improving molecular diagnostics in an endocrine surgery clinic in conjunction with a pathological laboratory. The aim of our work was a comparative analysis of the expression of cell cycle signaling molecules in various thyroid diseases: toxic goiter, adenomatous goiter, autoimmune thyroiditis and papillary cancer. We investigated the quantitative ratio of expression of apoptosis markers CD-95 (Fas-R) and Ki-67 mitosis detected in thyrocytes by immunocytochemistry and immunohistochemistry using standard protocols. The index Z = Fas / (Ki67 + 1) is proposed.

The performed cluster analysis of the Z-index calculated on the basis of punctate immunocytochemistry material allowed us to identify a group of patients relatively uniform in value (in this group, after the operation, the diagnosis of papillary cancer was histologically confirmed in all patients). Marker expression values were 2,3–9,0 for Ki67 and 0,9–4,1 for Fas, and the Z-index was in the range 0,6–3,9. It can be useful for the differential diagnosis of thyroid cancer based on punctate material, which is important when deciding on the amount of surgical intervention, as well as in the morphological substantiation of the prognosis of the disease.

Mathematical analysis showed that if the percentage of fissile nuclei visualized immunohistochemically with the Ki-67 marker is unpromising as a singular diagnostic indicator, then in combination with the apoptosis marker it plays an important role in a comprehensive assessment. These data are also interesting in the context of the pathophysiological pattern of inhibition of the expression of CD95 by tumor cells. This is important to justify the approaches of chemotherapy or immunotherapy of cancer of different tissue belonging.

El artículo busca dar a conocer las transformaciones que los periodistas deportivos colombianos vienen experimentando en la cobertura y retransmisión de megaeventos deportivos. Desde una metodología cualitativa, soportada en indagación documental, entrevistas y triangulación analítica, los hallazgos demuestran que la producción audiovisual y la interacción con la audiencia son una realidad, mientras que la irrupción del streaming es determinante. Aun así, se concluye que la realización de coberturas in situ fortalece la calidad informativa, aunque los grandes medios apuestan masivamente por lo contrario.
falta de tiempo público entre des-planificación urbana y componente identitario.
Authors: Valle Pilia Margherita
Published: October 2022

Este artículo presenta la discusión entre dos hipótesis nacidas en seno a la investigación académica que se desarrolló a lo largo de los cursos de Diseño Urbano. El enfoque de estas clases permitió discutir y analizar las posibles influencias de la planificación urbana en los fenómenos de vivencia del espacio público, así como del tiempo público ciudadano. Primeramente, se subrayaron las relaciones entre distintos conceptos a estudiar en términos globales. Por otro lado, se propuso una lectura específica del fenómeno en Costa Rica. Estas aproximaciones se desarrollaron mediante una investigación cualitativa basada en la revisión bibliográfica de fuentes que permitieron diseñar una investigación dirigida al diálogo entre los documentos. El enfoque crítico-histórico buscó construir una teoría que pudiera narrar la idiosincrasia costarricense en el ámbito de la vivencia urbana, entre su aspecto tangible de “espacio público”, así como de su contraparte socio-cultural y política, definida como “tiempo público”.

Published: October 2022

Modern video encoders like the AOMedia Video 1 (AV1) implement several complex tools to allow the required high level of compression efficiency. The Fractional Motion Estimation (FME) is one of these complex tools, and AV1 FME defines 42 different interpolation filters. To handle such complexity, hardware acceleration using approximate computing has become an interesting alternative to be explored. This paper presents three optimized approximate architectures for the AV1 FME interpolation filters. The architectures reach real time interpolation for UHD 4K videos at 30 frames per second in a low cost, low power, and memory-efficient design. The architectures were synthesized for a 40nm TSMC standard-cells technology reaching power gains up to 83%, when compared to a precise architecture, and up to 20% when compared to a previously published approximated solution. The area gains were also expressive: up to 83% and 40%, respectively. The architectures also allow a memory bandwidth reduction of up to 59.5%, in comparison with the state-of-the-art solutions. The approximations implied small coding efficiency degradation of 0.54% and 1.25% in BD-BR. The presented architectures have the best results found in the literature when considering the trade-off among hardware cost, power dissipation, processing rate, memory bandwidth, and coding efficiency.

Authors: Ceolin Giovana , Compassi Severo Lucas
Published: October 2022

To meet low power requirements for Internet of Things (IoT) applications, the power dissipation of RF transceivers must be very low. As the Low Noise Amplifier (LNA) is one of the most energy consuming parts of an RF receiver, its power optimization is necessary for modern IoT devices. This work presents a 170 $\mu$W LNA capable of operating at 2.4 GHz when powered by a 0.4 V source. It is based on an inverter-based amplifier with improved gate bias voltage and automatic forward bulk biasing to operate at the moderated channel inversion level. A biasing metric is explored to analyze the best dimensions and bulk bias voltages for the NMOS transistor. Post-layout simulation results shown a 2.8 dB noise and competitive specification values compared to the state-of-the-art low-voltage LNAs.
Organic Field Effect Transistors

Published: October 2022

This article begins with a brief overview of the structure, physical characteristics, and peculiarities of organic field effect transistors. The main differences from the silicon MOSFET are emphasized. The results of poly 3-hexylthiophene and cross-linked polyvinyl alcohol top gate-bottom contact transistors with different channel lengths fabricated by standard photolithography and plasma etching are described. Transistors showed good charge mobility, high ION/IOFF and excellent environmental stability. The Shockley model and the Transmission Line Method (TLM) were applied to characterize the transistors. Mobility was extracted by both methods and differences were discussed. The shorter the channel length and the higher the conductivity of the semiconductor, the greater the impact of contact resistance. In these cases, the use of TLM for parameters extraction becomes essential. The transistors were submitted to extended current-voltage measurements and drain current degradation was observed. Drain current as a function of the integral charge passing through the channel was investigated. The strong decrease in current was found to be related to reduced mobility of charge carriers. Reasons for this behavior are suggested.

Published: October 2022

This paper presents a historical analysis of reconfigurable field effect transistors (RFETs). History shows the naturalness of its development from the evolution of integrated circuits (ICs) technology. Next, its operating principles are detailed to further study the variety of structures proposed in the specialized literature. Among these structures, the Back Enhanced SOI MOSFET (BESOI MOSFET) has been studied in detail, which stands out for its simplicity of fabrication and the possibility of integration with conventional technologies. The BESOI MOSFET is used to present proofs of concept for RFET applications such as: reconfigurable digital circuits, light sensor, permittivity-based biosensor and charge-based biosensor. The latter may allow, for example, obtaining a glucose sensor. Finally, future perspectives of applications of RFETs are presented, as in systems of protection of the intellectual property of ICs.
Tunnel-FET Evolution and Applications for Analog Circuits
Authors: Agopian Paula Ghedini Der , Martino Joao A. , Simoen Eddy , Rooyackers Rita , Claeys Cor
Published: October 2022

In this work different generations of field effect tunneling transistor (TFET) are evaluated through DC digital and analog figures of merits. For TFET devices the main digital figure of merit is the subthreshold slope (SS), while for analog application the intrinsic voltage gain (AV) is the most important one. For the early generations, that are based on silicon, the SS does not reach values smaller than 60mV/dec at room temperature, however, the AV reaches values up to 80 dB, showing to be promising for analog applications. As the TFETs were being optimized for digital applications and consequently presenting better switching performance, the intrinsic voltage gain moves in the opposite direction. This opposite trend is related to which transport mechanism is predominant for each type of device. While III-V TFETs are more dependent on Band to Band Tunneling (BTBT), silicon devices are more relying on Trap-Assisted Tunneling (TAT). While BTBT allows for faster switching, TAT is less dependent on the drain electric field, so the former favors SS while the latter favors AV. Based on the good analog behavior of silicon channel TFETs, a two-stage operational transconductance amplifier (OTA) was designed with different TFET technologies and the compared results were discussed.

Semiconductor technology has known an exponential evolution during last decades, being the key for the further evolution of micro- and nanoelectronics and the commercial breakthrough of state-of-the-art innovative and sometimes disruptive applications. Microelectronics is fully integrated in different areas of everyday life, such as healthcare, automotive, communication, safety and security, smart energy, smart cities, retail business, etc. This evolution implies extensive research towards new materials (gate dielectrics, metallization, III-V materials, wide bandgap approaches, etc.), alternative device architectures (e.g., FinFETs, TFETs, negative capacitance, gate-all-around, nanowires, nanosheets in both horizontal or vertical configurations, SOI approaches) and optimized system functionality and density (3D integration, through silicon vias, sequential integration, SOC, and others). Besides advanced 2- and 3D transistors, also solar cells, bio-devices, organic devices are of great importance. Also the operation field of the devices, including frequency range, noise performance and temperature range, has to be optimized in function of the envisaged digital or analog application. The state-of-the-art, trends and challenges encountered during the fabrication and operation of different emerging technologies are reviewed in this special issue. Much attention is given to the excellent research being performed by different research groups at Brazilian universities and international research centers.

This is an experimental study on produced biogas volume and volume from co-digestion of cow dung and food waste. This study was carried out at ambient condition. A gas meter was used for the measurement of gas composition, biodigester operating parameter were measured using a multi meter while gas volume was obtained from the observation of the floating drum. Four floating drum digesters were used for the experiment. The digesters held 3300 g of feed each with varying ratios of 70:30 (Sample A), 50:50 (Sample B), 40:60 (Sample C), and 30:70 (Sample D) of cow dung to kitchen waste respectively. The dilution ratio was 1:3 of feed to water which had a retention time of 30 days. The gas composition (CH4, CO, CO2, H2S), substrate pH and temperature were monitored to observe the changes. The results gotten were graphed and tabulated. The gas gotten from the biogas burnt which shows that the biodigesters produced methane (CH4) of more than 40% of the gas composition at certain points during the retention time.

This paper examines the effect of reporting with International Financial Reporting Standards (IFRSs) on the quality of information disclosure in financial statements. To achieve the objective of the paper, two hypotheses were tested in line with the objectives of the study. The survey research design was adopted, and the population of 55 respondents gotten from eight (8) banks. But for the purpose of the analysis 48 sample size was used which constitutes the numbers of respondents from the eight (8) banks’ top management staff that are involved in the preparation of financial statements. The instrument used for data collection was titled “IFRSs Adoption and Quality of Information Disclosure (IFRSAQID)”. Based on the findings of the study, there is a strong and significant relationship between the quality of information due to the adoption of IFRS 16, and reporting in a common language due to the fact that the adoption improved the disclosure of more information. Based on this, it was recommended that banks should be encouraged to adhere to the requirements IFRSs in the recognition, measurement, and disclosure of financial information to reduce information asymmetry. Also, regulatory bodies should ensure strict compliance and defaulters should be penalized to reduce incessant financial scandals that have caused investors to lose a substantial amount of their wealth to reckless reporting in the past. The paper is very apt considering the information asymmetry that has existed for decades due to the adoption of IAS 17 replaced by IFRS 16, and using banks with international recognition because their operation is beyond the domestic banking system.
