Published: May 2021

The objective of this study was to evaluate the productivity and energy efficiency of tree extraction in mountainous regions by means of a tractor with winch in two work team compositions: I: one tractor operator and a cable operator; and II: one tractor operator and two cable operators. The study was carried out in Vale do Ribeira region using a full tree harvesting system through a time and motion study in different conditions of extraction distance (6 to 135 meters) and log yard (5 to 241 meters), and land slope (from 7 to 37º). To evaluate the cycles, a regression analysis was carried out for each treatment and subsequently compared using the Graybill F test. Then a regression with a dummy variable was performed. The productivity was 9.26 m3 PMH0-1 with a cable operator and 12.12 m³ PMH0-1 at an extraction distance of 100 m; the specific fuel consumption was 44.26 g kW-1 PMH0-1 in both treatments, and the energy efficiency was 4.92 g kW-1 m³ with a forest worker and 3.13 g kW-1 m³ with two forest workers. Consequently, although the specific fuel consumption was equal in both treatments, the increase in productivity resulting from the addition of a cable operator,improved the energy efficiency in the extraction using a tractor with winch.
Chatting with AI Bot: Vocabulary Learning Assistant for Saudi EFL Learners
Authors: Alsadoon Reem 
Published: May 2021

In the AI field of language learning, chatterbots are an interesting area for language learning and practice. This research investigates Arabic EFL vocabulary learning using an interactive storytelling chatterbot. A chatterbot was created and equipped with four vocabulary tools: a dictionary, images, an L1 translation tool, and a concordancer. The target words were enhanced by these tools to provide the learners with interactive comprehensible input. This project seeks to identify which tools are mostly used when EFL learners are practicing English with a chatterbot. It also seeks to determine which tool could help most in vocabulary learning as well as retention. The results of the study indicate that the dictionary is the most favoured and effective tool for vocabulary learning. For retention, the findings uncover that L1 translation is slightly (but insignificantly) higher than the dictionary.

Innovation in methods decentralized audit research
In the more than 15 years that decentralized audit offices have existed in the Netherlands, little attention has been paid to the research methods they use. This article focuses on how the research methods used by decentralized audit offices have developed and to what extent they use new technology. New technology has changed a lot in 15 years, which offers new possibilities for research, but also raises new questions. Based on an empirical analysis of audit reports, it can be concluded that decentralized audit offices adopt a standard approach to document and file analysis and interviews, with only limited application of innovative technology. On the basis of a theoretical exploration of the relevant literature and a simple qualitative analysis of research by the Netherlands Court of Audit and the Rathenau Institute, a framework has been developed in which the opportunities and risks of the application of new technology in decentralized audit office research are described. This can provide a handle for future application. Decentralized audit offices can use this for (more) reflection on their research methods and innovation, in order to develop to maturity while remaining young.

The impact of local audit office research: an empirical search for success factors of use
The impact of audit office reports has received little attention in the scientific literature. In this article, various forms of impact have been distinguished with the help of Public Administration literature and factors that promote the use of evaluations have been distinguished. This theoretical framework was subsequently used for empirical research into the effect of audit office research. The extent to which the recommendations have had an impact was investigated in 20 Dutch municipalities with the aid of impact reports from audit institutions. Out of 176 publications, 94% of the 1216 recommendations were adopted by the city council. This means that the procedural impact is high. Of the 731 recommendations that could be checked at 17 municipalities, the local audit offices report that 58% had been fully implemented, 19% partially and 15% not or not tackled differently. The three categories of success factors from the scientific literature were visible in the practice of the audit offices. This applies most strongly to impact factors related to evaluation quality, in particular the factors related to communications standards, clear recommendations, timeliness and relevance to the decision maker. As far as research and decision-making factors are concerned, the commitment of the organization and the political climate are the most important factors for audit institutions. Finally, the involvement of stakeholders promotes the impact as a catalyst. The article concludes with practical lessons for promoting the processing of audit reports.

Wanneer wordt een prijs op billijke wijze vastgesteld?
In deze noot bespreken wij de uitspraak van het Hof van Justitie in SABAM/Weareone.World en Wecandance. De uitspraak draagt bij aan een verder gedifferentieerd jurisprudentieel kader voor onbillijke prijzen en voorwaarden. De uitspraak verrijkt de bestaande rechtspraak waarin de onderliggende berekeningsmethode van vergoedingenmodellen van collectieve beheersorganisaties op billijkheid worden getoetst. In navolging van de conclusie van advocaat-generaal Pitruzzella in deze zaak reflecteren wij tevens op de toepasbaarheid van het oordeel van het Hof van Justitie in farmaceutische en platformmarkten.

Since the 19th century, the presentation of bovines with disproportionate muscle development have been associated with mutations that inhibit the action of the myostatin gene, it is referred to as double muscle mutation, which is common in some European Bos taurus breeds but it is not reported in buffaloes Bubalus bubalis. This study aims to evaluate if the phenotype observed in 6 young buffaloes with disproportionate muscle development has the same myostatin mutation reported in cattle. DNA was obtained from the blood of the animals of the Murrah breed. First, second and third exon was amplified end point PCR; the fragments were sequenced using capillary electrophoresis. Holstein cattle (Bos taurus) was used As control for normal phenotype. The results obtained from the comparison of the sequence of the myostatin gene show that the observed double-muscled phenotype did not show differences from normal controls. Interspecific variation was demonstrated by comparing exons two and three of the gene, finding 12 variations between the Bos taurus and Bubalus bubalis species in the evaluated fragments. It is necessary to study physiology, and the animals to explain the phenotype observed in buffaloes.

Símbolos en el atuendo de las mujeres mayas de la antigüedad. Una aproximación iconográfica a tres diseños singulares
Authors: Parpal Cabanes Esther 
Published: May 2021

Este artículo forma parte de una investigación de mayor envergadura que tiene como objeto de estudio la representación femenina en el arte maya a través de los elementos que conforman sus retratos y definen sus identidades. Tanto las joyas, como la pintura corporal, los tocados o las prendas de vestir, establecían un diálogo con el espectador de su tiempo que si se analiza e interpreta en la actualidad, también puede aproximar al investigador al conocimiento sobre sus portadoras. Por ello, en esta ocasión presentamos concretamente el análisis de tres símbolos que forman parte de la indumentaria de algunas mujeres de la élite maya, entre los cuales cabe destacar el que luce la noble Señora de K’anpat en su traje, retratada en los murales pintados hallados por el equipo de investigación del Proyecto La Blanca, Petén, Guatemala, en el sitio arqueológico de Chilonché, ya que no se había visto antes en ninguna otra representación textil.
El mito aéreo en el futurismo italiano: del periodo heroico a la espiritualidad aérea (1909-1944) The aerial myth of Itanian futurism: from the heroic period to the aerial spirituality (1909-1944)
Authors: Mancebo Roca Juan Agustín 
Published: May 2021

La poética de lo aéreo atravesó transversalmente la historia del futurismo italiano. El undécimo punto de su manifiesto y fundación en 1909, hizo referencia al aeroplano como una máquina esencial para comprender que la vida y el arte se debían someter a un mundo en permanente transformación. Lo aéreo y sus implicaciones compusieron proclamas y manifiestos determinando la creación literaria y artística del periodo heroico. En los años treinta, cuando el futurismo planteaba su supervivencia en el complejo contexto social y político italiano, la aeropintura se convirtió en su línea oficial. Un perfil que, desde ese mismo momento, se bifurcó en dos tendencias complementarias: la dedicada a una praxis orgánica de las variables de la mirada aérea y la de una política representacional que superaba lo aéreo para penetrar en lo trascendente. Con la desaparición de las líneas de identificación entre estética y política, la temática aérea adquirió el rol de propaganda del régimen, celebración de la guerra-fiesta, que recuperaba el discurso intervencionista de la Primera Guerra Mundial y que, tras un periodo de manifestaciones de escaso valor plástico, concluyó abruptamente con el deceso del futurismo que coincidió con el nuevo ciclo histórico que se inició en Italia.
The poetics of the aerial went through the history of Italian futurism. In 1909, the eleventh point of his manifesto and foundation referred to the airplane as an essential machine for understanding that life and art should be submitted to a world in permanent transformation. The aerial and its implications composed proclamations and manifestos which determined the literary and artistic evolution of the heroic period. In the 1930s, when futurism was planning its survival in the complex social and political context of Italy, aeropainting became its official line. A profile that bifurcated into two complementary tendencies from that very moment: one devoted to an organic practice of the aerial gaze variables and the other to a representational policy which went beyond the aerial to penetrate the transcendent. With the disappearance of the lines of distinction between aesthetics and politics, the aerial theme acquired the function of the regime's propaganda. It was the celebration of the war-fest that restored the interventionist rhetoric of the First World War and which, after a period of demonstrations of little plastic interest, ended abruptly with the death of Futurism, coinciding with the new historical cycle that began in Italy.
INFLUÊNCIA DO RESÍDUO DE PRODUÇÃO DE CERVEJA NO CRESCIMENTO DE FUNGOS Ganoderma E NA OBTENÇÃO DE β-GLUCANAS

Published: May 2021

A utilização de efluentes do setor cervejeiro como substrato em cultivos fúngicos torna-se uma alternativa sustentável de reaproveitamento de resíduos. Este trabalho avaliou a velocidade de crescimento micelial radial (Vm) e a produção de β-glucanas pelos fungos Ganoderma lipsiense e Ganoderma applanatum cultivados em placas de Petri contendo resíduo da centrifugação da cerveja Pilsen (RCP), previamente caracterizado quimicamente, nas concentrações bruta (T1), diluído 50% (T2) e 75% (T3), com medições radiais diárias durante 13 dias. Ao término deste período, os micélios foram removidos realizando-se posterior secagem (55°C) para quantificação de β-glucanas. A caracterização química do resíduo indicou a presença de fósforo (81,20 mg L-1), nitrogênio amoniacal (9,18 mg L-1), além de DBO (17.750,00 mg O2 L-1) e DQO (32.050,00 mg O2 L-1). Todas as concentrações de resíduo proporcionaram crescimento micelial e produção de β-glucanas. Em T1, foram obtidos maiores Vm (4,48 e 3,90 mm dia-1) para G. applanatum e G. lipsiense. Em relação as β-glucanas, G. lipsiense apresentou maiores teores (32 %) no T2 e 30,28% no T1, enquanto G. applanatum produziu teores abaixo de 20%. Os resultados mostram a influência da concentração do meio de cultivo e da espécie fúngica na produção de biocompostos e sugerem que o RCP estudado pode ser reaproveitado, sendo empregado como substrato para produção de compostos de interesse farmacêutico, tais como β-glucanas.

Authors: Ongori Josephine G. , Kitainge Kisilu 
Published: May 2021

Aims: The objective of the study was to examine the influence of KEMI’s capacity building programme on head teachers’ competencies in financial management
Study Design: The study adopted the concurrent triangulation design where both quantitative and qualitative approaches were employed to collect information and do the analysis at the same time.
Place and Duration of Study: This study was conducted in Uasin Gishu County of North Rift region. The county lies within latitude: 0° 31' 0.00" N and longitude: 35° 16' 59.88" E. The study was carried out between May 2019 to October 2019
Methodology: The study targeted six sub-county education officers and 471 head teachers in public primary schools in the county. Simple random sampling was employed in choosing 30% (141) of the public primary schools proportionately from each of the six sub-counties in the county. Every head teacher of the selected public primary schools took part in this study. Data was also gathered from all the six sub-county directors of education of Moiben, Kesses, Turbo, Kapseret, Ainabkoi and Soy. Data was collected using interviews and questionnaire.
Results: Findings indicated that there was a moderate positive correlation between KEMI capacity building programme and head teachers' competency in financial management. KEMI capacity building programme on head teachers competencies had a positive and significant influence on financial management (r (132) = .309, p< .0005). Thus the hypothesis (Ho4) was rejected and this can be explained further by stating that there exists a relationship.
Conclusion: The findings also shows that KEMI had helped head teachers in understanding the budgeting, auditing of the books of accounts, management of income generating activities and improved accountability and transparency of finance. KEMI had also helped head teachers in keeping up to date inventories. KEMI had enhanced head teachers’ adherence to the school budget and to appreciate the need for constituting of tendering committee.

Published: May 2021

Background: With increasing morbidity and mortality rates throughout the world, COVID-19 has caused a universal psychological impact on the lives of people.
Aims: To examine psychological wellbeing of frontline healthcare professionals and compare mental health among doctors, paramedical staff and allied health workers.
Methods: This cross-sectional study included 225 healthcare professionals from 13 different hospitals in Karachi, Pakistan. The symptoms of depression, anxiety and insomnia were assessed using the 9-item Patient Health Questionnaire (PHQ-9), the 7-item Generalized Anxiety Disorder (GAD-7) and the 7-item Insomnia Severity Index (ISI) respectively.
Results: Major findings of the study were that 44.7% participants had no depression, 38% were reported to have mild anxiety and 3.5% had severe insomnia. Insomnia was correlated with anxiety and depression leading to moderate correlation of 0.516 and 0.694 in both with a highly significant p value (p=0.001 and p=0.001). A significant association of depression was seen with healthcare providers and years of experience with (p=0.009) and (p=0.010) respectively. Levels of anxiety were associated with occupation and years of experience that led to the finding that doctors suffered more from mild anxiety (83.5%) whereas years of experience had no significant association. Correlation of insomnia with occupation and years of experience led to the finding that sub threshold insomnia was found in 29% participants, where majority of participants were allied health workers. However, borderline significant association was found between insomnia and the number of years of work experience (p=0.049).
Conclusion: It is concluded that frontline workers experienced different levels and symptoms of psychological distress in this pandemic.
In Situ Precipitated Calcium Carbonate in the Presence of Pulp Fibers – A Beating Study
Authors: Dölle Klaus , Bajrami Bardhyl 
Published: May 2021

The paper industry around the world is in search for new ways to decrease production costs. New approached with additives such as new developed In Situ precipitated paper fillers materials have the potential to reduce production cost and increase profit margins.
In Situ precipitated calcium carbonate filler with 20.9% and 41.7% filler material was produced in a large-scale laboratory unit using a eucalyptus pulp fiber suspension with a 1.7% fiber solids content.
Laboratory beating tests were performed with a Valley Beater and APFI Mill using pure eucalyptus pulp with no filler content as the based trial and the two-laboratory manufactured In Situ precipitated filler pulps.
Valley Beater and PFI Mill laboratory beating machines show similar differences/trends for the breaking length, tear and burst index.
EC-pulp with no filler has the highest strength for breaking length, tear and burst index. With increasing filler level breaking length, tear and burst index decrease. Filler containing pulp shows a decrease in beating time for the same beating level. 20 minutes for the Valley Beater and 15000 revolutions for the PFI mill show highest change in pulp fiber beating level sufficient for paper making operation.
Valley Beater and PFI Mill laboratory equipment operate different and an exact comparison of the beating curves is not possible. Based on the amount of pulp fiber needed for experiments the Valley Beater for large amounts and the PFI mill for smaller amounts should be selected.
The SEM pictographs of the Valley Beater and PFI Mill beating trials from 0 stage to the high beating stage at 80 minutes for the Valley beater and 60000 revolutions for the PFI Mill show similar results. No damage to the fibers is noticeable at the unbeaten level. With increasing beating level. At a magnification of 430 times the fiber structure shows an increasing dense fiber structure with less visible pores. Magnification of 2500 times reveals increasing damage to the fiber wall and fiber surface.

Study Design: The surveys were conducted in the villages of all the territories of the Kasai Oriental province in RD CONGO for five years and nine months, from March 2013 to December 2018. The confirmation of the identified species was made at the Laboratory of the ISP Mbujimayi and Herbarium of the ecology laboratory of the Department of Biology of the University of Kinshasa.
Place and Duration of Study: The surveys were conducted in the villages of all the territories of the Kasai Oriental province in RD CONGO for five years and nine months, from March 2013 to December 2018. The confirmation of the identified species was made at the Laboratory of the ISP Mbujimayi and Herbarium of the ecology laboratory of the Department of Biology of the University of Kinshasa.
Methodology: Pre-established questionnaires were submitted to healers and potential patients living in the region. Data were collected on local phytotherapeutic practices in order to identify indigenous plants used in the treatment of bacterial diseases. The plants listed have been identified and their eco-morphological characteristics were determined.
Results: From examination of the responses of 391 traditional healers and 1,485 residents and potential patients questioned, one hundred and sixteen plant species reputed to be effective against bacteriosis were identified. They belong to 19 orders, 39 families and 87 genera. Among these plants, only 6 families (Fabaceae, Euphorbiaceae, Rubiaceae, Phyllanthaceae, Lamiaceae and Moraceae) provide 51.57% of the species used against bacterial pathologies i.e more than half. Woody plants (62.94%) predominate among the species used (27.59% of trees, 27.59% of shrubs). Wild savannah species (44.83%) and pantropical ones (32.76%) are the most numerous among the plants of Kasai Oriental which provide drugs against bacteriosis.
Conclusion: The results confirm that several local plant species are commonly used to treat bacterial diseases in Kasai Oriental. Local herbalists use more phanerophyte plants from savannah and especially trees and shrubs.
