Authors: Jaunik Martina , Kovač Marjeta , Bedenik Klemen , Marinšek Miha
Published: September 2024

The aim of the study was to compare the effectiveness of interventions promoting fundamental motor skills (FMS) in preschoolers and first-year schoolchildren in north-east Slovenia and to investigate possible gender differences. The study involved 143 children with typical development aged four to seven years, divided into an experimental group and a control group. The experimental group took part in a 13-week intervention programme, while the control group followed the standard curriculum for physical education in Slovenian public kindergartens and schools. The test of gross motor development 3 was used to assess the improvement of FMS. The results showed that after the intervention, the improvement in locomotor and ball skills were in preschool children higher than in first-year schoolchildren. No gender differences were found in FMS improvement. These results have important implications for the development of FMS in young children and for the design of intervention programmes promoting these skills.
Cycling in Kindergarten: Highlighting Aspects of Integrating Cycling in Educational System
Authors: Gregorc Jera , Štemberger Vesna
Published: September 2024

In this paper we examine the importance of including cycling in the educational system, starting at pre-school age. 74 children aged 4-5 years, 74 parents of 4-5 year olds and 4 preschool teachers participated in the study. We investigated the differences in the parents' and teachers' assessment of the children's cycling skills. We found that parents rated all observed cycling skills of their children better than preschool teachers (Wilcoxon signed ranks test: TS = 184.5 (74); p < 0.001). Children who find better conditions for cycling in their family environment are more skillful (Mann-Whitney test: U = 844.0 (74), p < 0.042), but the cycling skills of the children do not correlate with the cycling frequency of their parents (Spearman's rank correlation test: ro = -0.163 (74), p < 0.164). We conclude that it would be worthwhile to systematically introduce cycling both in preschool and in preschool teacher education.

Analysis of furin (FURIN) gene expression in the U-87 MG cell line as a potential target for gene inhibiting therapies in (auto-) immune diseases
Authors: Zapletal-Pudełko Karolina , Machnik Grzegorz , Stec-Grosman Katarzyna , Bułdak Łukasz , Okopień Bogusław
Published: September 2024

Purpose: Furin is a proprotein convertase commonly found in the human body. The enzymatic activity of furin is necessary for the activation of numerous substrates including e.g. hormones and growth factors. Nevertheless, furin is involved in various pathological conditions caused by, among others, chronic inflammation. Therefore furin is considered as a potential target in autoimmune diseases therapy.
We performed an experiment in which the expression of FURIN gene in U-87 MG astrocytoma cells was investigated. Additionally, this cell line contains some sequences coding human endogenous retroviruses (HERVs), including ERVW-1 and its receptor- SLC1A5. Deregulation of HERV expression has been observed in some neurodegenerative diseases as well as in inflammatory process.
Material and Methods: Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot (WB) techniques were utilized for analysis. Phorbol 12-myristate 13-acetate (PMA) were used for cell stimulation. Short interfering RNAs (siRNA) were used for gene expression inhibition in U-87 MG cells in vitro.
Results: Cell stimulation by PMA strongly increased FURIN expression, simultaneously downregulating ERVW-1 (p<0.01). Moreover addition of PMA significantly stimulates the autocatalytic action of cellular furin itself resulting in the dissociation of its propeptide that was clearly visible in a time-dependent manner. SiRNA-mediated expression inhibition of ERVW-1 and FURIN influenced the mRNA level for SLC1A5 (ASCT2) - primary syncytin-1 receptor, that was significantly lower. FURIN inhibition by siRNA caused strong upregulation of ERVW-1 expression (p<0.01).
Conclusion: Our results showed that stimulation by PMA and inhibition expression by siRNA affects the expression of FURIN in U-87 MG astrocytoma cells. Moreover, furin shows a complex relationship on the expression of ERVW-1 and SLC1A5 genes, as well as on the form (precursor or mature) and the amount of the final translation products of the transcripts. The regulation of FURIN may pose a potential therapeutic strategy in the treatment of neurodegenerative diseases caused by autoimmunity.
Cytoplasmic male sterility in plants with special emphasis on sugar beet
Authors: Sadzik Gabriela
Published: September 2024

The phenomenon of cytoplasmic male sterility (CMS) in plants is characterized by a disturbance in the development of functional pollen. The cause of this disorder is the incompatibility of the mitochondrial and nuclear genome. Determinants of CMS are found in the mitochondrial genome and are inherited maternally. Nuclear Rf genes are responsible for restoring male fertility in CMS plants most often by posttranscriptional and/or posttranslational activity on mitochondrial gene expression. Two fertility restoring genes have been identified in sugar beet plants, of which Rf1 is the best characterized. It is concluded that the translation product of this gene acts as a molecular chaperone leading to inactivation of a specific mitochondrial protein that is a marker for the CMS trait in sugar beet. The CMS phenomenon is applied in the commercial breeding of hybrid varieties of many crop species. Exploiting heterosis is easier with the knowledge of cytoplasmic (mitochondrial) determinants of sterility and corresponding restorer genes.

Childbirth Doula Training and the Experiences of Those Who Train as a Childbirth Doula
Authors: Jefford Elaine , Hinton Jordanna , Provost Steve , Marsden Julia , Ebert Lyn
Published: September 2024

Objective:The objective of this article was to gain a deeper understanding and insight into the training and characteristics of childbirth doulas on the maternity care team. The aim was to integrate knowledge obtained from two studies: an integrative review (IR) of doula education programs globally (Study 1) and the qualitative experiences of those training to become a doula (Study 2).

Methods:For the IR (Study 1), the modified Whittemore and Knafl (2005) framework and Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines were used. Five electronic databases were searched (CINAHL, ProQuest Education Databases, ERIC, MEDLINE, and Scopus) usingdoulaandeducation/trainingas key terms. Nineteen papers were included in the review. For the qualitative study (Study 2), semi-structured interviews with 10 student doulas were analyzed using inductive thematic analysis.

Results:The results highlighted ambiguity around the education (review) and scope of practice (qualitative) of a childbirth doula. The review showed a variety in duration, content, learning, certificate/accreditation, and educator qualifications in doula training programs, globally. The variety in student doulas’ understanding of their role in the maternity care context emerged from the key themes: (a) what influenced the decision to become a doula, (b) personal attributes perceived as essential to be a doula, and (c) what constitutes the role of a childbirth doula.

Conclusions:This article highlights a variability in doula training legislation and accreditation, as well as program content and length. This variation may be reflected in student doulas’ understanding of their role in the maternity context. A better understanding of doula training and a defined scope of practice can fill the current gap in continuity of care and improve communication within the maternity care health team.

A pesar de la importancia del agua para la vida, su uso ha sido excesivo y su tratamiento escaso. Ante la constante escasez hídrica, el tratamiento para reutilizar el agua residual se ha tornado de gran importancia; sin embargo, los métodos convencionales son poco replicados por los altos costos de construcción y operación. El objetivo del presente estudio fue evaluar un sistema ecológico de tratamiento de aguas grises mediante humedales bioingenieriles sembrados con plantas ornamentales, con aditamentos para entrada de oxígeno ambiental y suministro de carbono. Se evaluó un sistema domiciliario para 3 habitantes, que incluyó 8 celdas con plantas y 4 controles sin vegetación (12 celdas, considerando réplicas). Todos los sistemas se rellenaron de residuos rugosos de pet. De los mesocosmos con plantas, dos tenían respiraderos; 2 tenían fuente extra de carbono; 2 tenían la combinación de difusores y residuos de coco, y 2 más sin presencia de coco ni difusores. Durante 12 meses se midió NT y SST. Se observó que, en cuanto a los SST, el sistema más eficiente en la remoción fue el que únicamente tenía plantas con el 64.5%; en cuanto a la eficiencia en la remoción de NT, esta fue del 65% en mesocosmos sin planta, incluyendo respiraderos y coco, y entre 80-86% en los otros mesocosmos con plantas, lo cual indica que el conjunto de oxigeno que proveen las plantas y el de los difusores, más la materia orgánica adicionada son una opción a replicar en los nuevos diseños de humedales para mejorar las remociones, principalmente de nitrógeno total, ion de difícil remoción en humedales.

Dynamique saisonnière de l'infestation des bovins par les tiques (Ixodoidea) dans les hauts plateaux de l'Ouest du Cameroun. II. Elevage extensif traditionel
Authors: Merlin Pierre , Tsangueu P. , Rousvoal D.
Published: September 2024

La dynamique des tiques sur les bovins de l'élevage extensif traditionnel a été suivie pendant un an sur six sites représentatifs des haut plateaux de l'Ouest du Cameroun. Boophilus decoloratus est retrouvé sur tous les sites toute l'année. B. annalatus est limité aux zones basses où il transmet la babésiose lors de la transhumance de saison sèche. Amblyomma variegatum est d'autant plus abondant que l'altitude est basse. La vague des larves a lieu en novembre-décembre, celle des nymphes de janvier à avril et celle des adultes de mars à juin. Bien que le taux d'infection par Cowdria soit sans doute élevé, le nombre de cas clinique est faible. La dermatophilose a une incidence élevée. Rhipicephalus lunulatus et Rh. sulcatus sont présents sur tous les sites en saison des pluies. Rh. longus apparaît en début de saison des pluies sur le plateau de Sabga. Haemaphysalis aciulifer, Hyalomma marginatum rufipes, H. nitidum et Ixodes cumulatimpunctatus ont une incidence trés réduite. Alors que pour l'élevage amélioré, la lutte contre les tiques doit se poursuivre toute l'année, en élevage traditionnel, les traitements acaricides n'auront lieu que de mars à juillet.

Published: September 2024

Quatre essais d'alimentation intensive ont été effectués pour connaître le potentiel de croissance des moutons de race Mossi et Peul de la région du Yatenga. Ils devaient permettre d'établir des rations destinées à la vulgarisation. Les gains moyens ont été compris entre 73 et 133 g, le poids des carcasses chaudes entre 9,2 et 15,7 Kg. Les consommations moyennes de matière séche pour un mouton de 25 kg ont varié de 1 à 1,2 kg. Les indices de consommation (kg M.S. d'aliment/kg gain) ont été compris entre 5,6 et 11 pour l'ensemble des lots. Cet indice à varié de 7 à 8 pour la ration paille-mélasse-tourteau de coton qui s'est retrouvée la plus appropriée pour être diffusée auprés des agriculteurs-éleveurs de la région.
Variabilité de la croissance des veaux et jeunes bovins dans les troupeaux sédentaires du Nord de la Côte-d'Ivoire
Authors: Poivey Jean-Paul , Menissier F. , Vissac Bertrand , Moussa K.
Published: September 2024

C'est à partir des opérations de contrôle de performances développées dans une cinquantaine de troupeaux sédentaires et communautaires de 6 régions du Nord de la Côte d'Ivoire, qu'a été estimée l'incidence des principaux facteurs de variation sur la vitesse de croissance mensuelle et le poids de 1564 veaux et jeunes bovins, de la naissance à 2 ans. L'analyse met en évidence l'importance relative de la saison, de l'âge et du type génétique (Baoulé , N'Dama, Métis Zébus, métis Baoulé x N'Dama et indéterminés) ainsi que des interactions entre ces facteurs. En particulier, l'effet de la saison devient trés important pour les veaux agés de plus de 3 ou 4 mois dont la croissance dépend plus des disponibilités fourragères qualitatives et quantitatives. Cependant pour les jeunes veaux, de tels effets sont largement atténués par la production laitière des mères. De plus les bovins Baoulé, qui présentent une vitesse de croissance plus faible que les N'Damas, manifestent des variations saisonnières de cette vitesse relativement plus faibles que celles des autres types génétiques. Enfin pour les croisés Baoulé x N'Dama, on note un effet d'hétérosis plutôt élévé sur la vitesse de croissance des veaux jusqu'à l'âge de 6 mois, effet qui devient négatif au-delà de cet âge lorsque la croissance ralentit.
Résultats d'une enquête zootechnique et économique sur l'élevage du buffle d'eau dans l'est de la Thaïlande
Authors: Mandret Gilles
Published: September 2024

Une étude de cas a été réalisée en 1983 sur l'élevage du buffle d'eau dans l'est de la Thaïlande. L'auteur analyse l'importance de cet élevage dans la région frontalière d'Aranyaprathet à partir de la structure des troupeaux, de leur mode d'alimentation, des performances, la prophylaxie, de l'association agriculture élevage et du marché des animaux. Les petits élevages sont majoritaires et 95 p. 100 des troupeaux ont moins de 10 têtes. Le caractère "naisseur" est trés net, bien que le marché des animaux de boucherie soit important. Les performances des animaux sont plus faibles mais pourraient être améliorées par une alimentation plus riche. L'association agriculture-élevage est primordiale dans la mesure où l'animal représente l'outil de travail. Quant au marché des animaux, s'il représente 7000 transactions par an pour le seul district de Wattana Nakhon, la demande reste toujours supérieure à l'offre.

La forte pression démographique humaine du Burundi impose une modification des systèmes d'exploitation, avec notamment une mode d'élevage bovin en stabulation prolongée. Cette nouvelle méthode qui nécessite des investissements peut être rentabilisée par une production laitière valorisée, en commune de Mbuye, Grâce à la création d'une unité artisanale de fabrication de fromage (fruitière). La collecte du lait est faite à pied chez les éleveurs environnants, soit par deux collecteurs rémunérés à la tache, soit par les producteurs eux mêmes. Divers essais on permis de définir une recette de fabrication originale: le fromage de Mbuye est une pâte pressée non cuite à croute lavée, fabriqué sans source de froid. Il est commercialisé surtout dans la capitale où il est apprécié. Le rendement technique est bon. La qualité bactériologique peut être améliorée. L'apport monétaire au producteur de lait contitue un stimulant pour le développement de l'élevage laitier dans la région.

Agricultura de Baixo Carbono no Brasil
Authors: Perosa Bruno
Published: September 2024

A expansão da produção agropecuárias nas últimas décadas gerou aumento de emissões de cases causadores do efeito estufa (GEEs), como carbono, metano e óxido nitroso. De forma a mitigar essas emissões, uma série de técnicas produtivas denominadas agricultura de baixo carbono (ABC) vem sendo adotadas e exigidas em vários mercados importadores. A difusão da ABC depende fundamentalmente que policy makers e consumidores possam monitorar o processo produtivo e contabilizar qual o impacto dessas técnicas sobre as emissões do setor agropecuário. Para isso, o Brasil vem buscando a construção de um sistema de Monitoramento, Relato e Verificação (MRV). O presente trabalho analisa os desafios da construção de um MRV para uma agricultura tão ampla e diversa como a brasileira. Para isso, são analisadas experiencias internacionais de MRV bem como os instrumentos de MRV que vem sendo desenvolvidos no Brasil. Observou-se que apesar de boa parte das políticas para adoção de ABC se mostraram efetivas, permitindo o cumprimento da maior parte das metas estabelecidas pelo Plano ABC (2011), várias dificuldades de monitoramento e governança observadas ao longo da década de 2010 precisam ser solucionadas no Plano ABC+ (2021), de forma a potencializar os incentivos para agricultores. O crédito público e a diferenciação de mercado dos alimentos produzidos com técnicas de baixo carbono dependem de uma melhoria nos sistemas de monitoramento e governança, o que representa um gargalo fundamental para que o Brasil possa atingir seu potencial de mitigação no setor agropecuário.

Regarding wills, there are fundamental differences between the Civil Code and the Compilation of Islamic Law. The difference is in the will made without a Notary deed or orally which is recognized in KHI, but not recognized in the Civil Code because it is not written and not made before a Notary. Whereas the issue of wills in inheritance is very vulnerable to disputes between heirs, where later the evidentiary power of the will is very decisive for the settlement of disputes that occur. Dispute resolution is closely related to evidence. The difference makes many parties, especially heirs, a dilemma to follow the provisions of KHI or the Civil Code. Therefore, it is necessary to study the ideality of the will form in evidentiary law. This is important, because it is not uncommon for inheritance issues to become objects of dispute. Therefore, the researcher formulates a problem formulation regarding "How is the ideal form of will in the scope of evidentiary law in Indonesia?" The research method used is normative with literature study. The results of the study concluded that in general, the form of wills in KHI and the Civil Code is ideal to be used as evidence. However, the most ideal will is a will in the form of an authentic deed because it has perfect evidentiary power and in the hierarchy of evidence as regulated in Article 164 HIR / 284 RBG Jo. Article 1866 of the Civil Code, the authentic deed has the highest position.Keywords: Proof; Legacy; Testament
AbstrakMengenai wasiat, terdapat perbedaan yang fundamental antara KUHPerdata dengan Kompilasi Hukum Islam. Perbedaannya pada wasiat yang dibuat tanpa akta Notaris atau secara lisan yang diakui dalam KHI, namun tidak diakui dalam KUHPerdata karena tidak tertulis dan tidak dibuat di hadapan Notaris. Padahal persoalan wasiat dalam kewarisan sangat rentan terjadinya sengketa antar ahli waris, di mana nantinya kekuatan pembuktian dari wasiat sangat menentukan untuk penyelesaian sengketa yang terjadi. Penyelesaian sengketa, sangat berkaitan erat dengan pembuktian. Perbedaan tersebut membuat banyak pihak terutama ahli waris menjadi dilema untuk mengikuti ketentuan KHI atau KUHPerdata. Oleh karenanya, perlu dilakukan kajian mengenai idealitas bentuk wasiat dalam hukum pembuktian. Hal ini penting, karena tidak jarang persoalan waris menjadi objek sengketa. Oleh karena itu, peneliti merumuskan suatu rumusan masalah mengenai ‘Bagaimanakah bentuk wasiat yang ideal dalam ruang lingkup hukum pembuktian di Indonesia?’ Metode penelitian yang digunakan adalah normatif dengan studi kepustakaan. Hasil penelitian menyimpulkan bahwa secara general bentuk wasiat dalam KHI dan KUHPerdata ideal untuk dijadikan alat bukti. Meskipun demikian, wasiat yang paling ideal adalah wasiat yang berbentuk akta otentik karena mempunyai kekuatan pembuktian yang sempurna dan secara hierarki alat bukti sebagaimana diatur dalam Pasal 164 HIR/284 RBG Jo. Pasal 1866 KUHPerdata, akta otentik mempunyai kedudukan yang tertinggi.Kata kunci: Pembuktian; Waris; Wasiat

Providing murabahah financing using collateral from a decision letter that has been made using an authentic deed, however, in practice there is use of collateral that is not included in the guarantee category. The problem discussed is how to protect the Ba'I law when the authentic deed of financing a murabahah with the guarantee of a decree is in default. This research is normative legal research with a statutory and conceptual approach. As a result of the discussion and research carried out, it can be concluded that the implementation of providing murabahah financing using the guarantee of a decree cannot be executed if a default occurs by the mustarib party. Decree guarantees are not included in the collateral category because they have no value and cannot be transferred. So, ba'i will experience difficulties and will not be able to maintain the health of the bank. The authentic deed remains valid in the process of making it.Keywords: Ba'i, Guarantees, Mustari, Murabahah financing, Syariah banking.

Visual Imitation Learning from One-Shot Demonstration for Multi-Step Robot Pick-and-Place Tasks
Authors: Lu Shuang , Haerdtlein Christian , Schilp Johannes
Published: September 2024

Imitation learning, also known as programming by demonstration, has been shown to be a promising paradigm for intuitive robot programming by non-expert users. However, the classical kinesthetic approach with physical hand guidance suffers from generalizability across different robot types and is impractical for demonstrating tasks with long horizons. Visual imitation learning enables the recording of multi-step tasks as a single continuous video, allowing non-experts to demonstrate tasks naturally. Existing approaches typically require a large amount of data to develop end-to-end deep learning models that map raw pixels to robot actions. This paper explores the application of visual imitation learning from one-shot demonstration, significantly reducing the data requirements and simplifying the programming process. To achieve this target, a framework is proposed to map hand trajectories to the robot end-effector, consisting of four essential components: hand detection; object detection; segmentation of the trajectories into elemental skills; and learning the skills. Methods are developed for each component and evaluated on recorded videos to demonstrate the effectiveness of the proposed framework.
Various Prospects of Biodiesel Production: Techniques and Challenges

Published: September 2024

Globally, the fuel demand is increasing rapidly and the conventional method to produce fuel is toxic which causes environmental degradation and climate crisis. Therefore, biodiesel emerges as the substitute to overcome the conventional fuel problems because biodiesel is renewable and non-toxic. Biodiesel synthesis is the process of using fats and oils to produce biodiesel ester and glycerol. Biodiesel can be produced using edible and non-edible feedstock but using the edible feedstocks problems like fuel vs food, nutritional value and economic considerations were raised. Therefore, non-edible feedstocks are being used to overcome problems arising from edible feedstock. As non-edible feedstocks can easily be grown anywhere on land, doesn’t cause imbalance to food economy and has low cost. Many non-consumable seeds like Mahua, Jatropha, Castor, Neem etc. are used to produce biodiesel. Now a days, researchers are using nanoparticles to enhance the stability, quality, and properties of biodiesel. In future, researchers can use algae and microbial oils for production of biodiesel. Research can also use biojet fuel in such a way that it reduces the carbon emission. In future, production of biodiesel can be integrated into circular economy models to reduce environmental waste and impact. In this review we will discuss the production methods for biodiesel, catalysts for biodiesel production, and non-edible feedstock properties of biodiesel.
The Impact of Induced Stress on Reactive and Proactive Control in Depression
Authors: Masuyama Akihiro
Published: September 2024

Background. Depression, a widespread mental health issue, is often marked by impaired cognitive control, particularly in managing proactive and reactive processes. The Dual Mechanisms of Control (DMC) framework differentiates between these two modes of cognitive control: proactive control involves sustained goal maintenance, while reactive control is more stimulus-driven and transient. Stress, known to exacerbate cognitive dysfunction in depression, may influence the balance between these control processes, though the specific effects remain poorly understood. This study aimed to investigate how acute stress influences proactive and reactive control in individuals with depressive symptoms. Methods. A total of 88 participants were divided into high-stress and control conditions and further categorized based on their depression levels, measured using the Beck Depression Inventory-II (BDI-II). Cognitive control was assessed using the AX-Continuous Performance Task (AX-CPT), both before and after exposure to a stress-inducing anagram task, which was designed to differentiate between high-stress and low-stress conditions. Results. Participants exposed to the high-stress condition reported significantly greater stress and fatigue levels compared to the control group, validating the stress manipulation. Although the balance between reactive and proactive control, as measured by the Proactive Behavioral Index (PBI), did not show significant changes, depressive individuals in the high-stress condition exhibited a significant decline in their ability to retain contextual information, as indicated by a reduction in the d-context index. This suggests that depressive individuals are particularly vulnerable to stress-induced impairments in proactive control. Discussion. These findings highlight the selective impact of stress on proactive cognitive control in individuals with depressive symptoms, shedding light on a potential cognitive vulnerability in depression. While the balance between reactive and proactive control remained stable, the impaired retention of contextual information post-stress points to a specific deficit in proactive control. This could have implications for targeted cognitive interventions, such as cognitive control training, aimed at enhancing resilience against stress in depressive populations. Future research should explore the long-term effects of stress on cognitive control, particularly in clinically diagnosed individuals.
Performance of Permeable Pavement Systems: A Review and Future Solutions
Authors: Terkura Simon Avaungwa , Akib Shatirah
Published: September 2024

Rapid urbanisation and city expansion worldwide have significantly increased impervious surfaces such as roads, buildings, and pavements. These impervious surfaces impede water infiltration into the ground, resulting in escalated surface runoff during rainfall. This has been exacerbated by climate change and heightened precipitation levels, resulting in recurrent annual flooding. Conventional drainage systems are now insufficient to cope with the amplified surface runoff, contributing to the escalating flood occurrences. Sustainable urban drainage systems such as green roofs, swales, and permeable pavements were developed as modern flood control techniques to replace the traditional drainage system approach by optimising resource utilisation and developing novel and more productive technologies. While most SUD techniques are sustainable in design, construction, and operation, permeable pavements are considered one of the least sustainable SUD techniques. This has garnered considerable attention from researchers who have been studying the design of a more sustainable permeable pavement system by utilising sustainable and recycled materials. This paper reviews the performance of permeable pavements systems using findings from extensive reviews and analyses of scientific publications on permeable pavements. It introduces a future solution and design of permeable pavements using recycled materials. The study will consist of two permeable pavement systems, one incorporating recycled materials in its layers and the other using traditional construction materials. The data collected from both systems will be compared to determine their performance.
