The EU and the Arctic: European foreign policy in the making
Authors: Wegge Njord
Published: September 2023

The EU is currently reviewing its interests in the High North and has recently started developing an Arctic policy. This article aims at explaining this foreign policy expansion by applying a theoretical framework consisting of three levels: (1) the internal level – viewing EU foreign policy (EFP) as the product of an “organization;” (2) the state level – in specifically accounting for the role played by external actors, primarily states; and (3) the systemic level – viewing the EU and its foreign policy as dependent on structural conditions within the global system. Through interviews, document studies, as well as existing scholarly research, the article identifies impact from all three analytical levels, including how the supranational and member-state level combined has been decisive in shaping the final policy outcome. The research identifies the crucial role played by other Arctic states, particularly Canada and Norway. Finally, on the systemic level, key conditions such as global warming and economic forces are recognized as relevant explanatory factors behind the development of the EU’s Arctic policy.Keywords: EU Arctic policy, European foreign policy (EFP), International rela- tions (IR).Citation: Arctic Review on Law and Politics, vol. 3, 1/2012 p. 6–29.

The Axiological Approach to the Regulation of the Right to a Favourable Environment
Authors: Permilovskiy Mikhail
Published: September 2023

The article is devoted to the problems of the integrative function of axiology as a special philosophic area which studies the axiological phenomena of objective reality. The analysis of different interpretations of values in philosophical, general legal and ecological sense is fulfilled. The axiological approach in regulation of the right to a favourable (healthy) environment is expressed in its allotment with particular primacy in relation to other main human rights and freedoms. In this article the ecological problems of the Arctic and the questions of its development are examined. Attention is focused on the problems of international cooperation in the field of environmental protection of the Arctic as well as on the ways of preserving its sustainable development. In the present article the ecological situation in Arctic countries is examined in terms of the Arkhangelsk region of the Russian Federation. The significance of law enforcement in protection of ecological human rights and the role of the axiological approach in the practice of the Constitutional Court of the Russian Federation (CCRF) are investigated. In the article the problems of compensation for damages caused by infringements on ecological law are determined, and an attempt is made at solving these. Significant attention is paid to the necessity of theoreti- cal and practical usage of the axiological approach in the regulation of the right to a favourable (healthy) environment on the international and domestic levels.Keywords: Arctic, axiology, ecology, value, right to a favourable environment, health, best existing technologies.Citation: Arctic Review on Law and Politics, vol. 3, 2/2012 pp. 162–185.

New Developments in Russian Regulation of Navigation on the Northern Sea Route
Authors: Solski Jan Jakub
Published: September 2023

The regime of navigation on the Northern Sea Route (NSR) is still largely based on legislation adopted by the Soviet Union, and features certain deviations in the way Russia’s international legal rights and obligations are implemented. In recent years the Russian Federation has demonstrated interest in revising NSR legislation with the preparation of one single comprehensive Federal Act on the NSR, and also a Federal Act to introduce amendments to pre-existing legislation. The latter option has gained the support of legislators, as the newly promulgated Federal Law on the NSR, dated July 28th 2012, No. 132 FZ, established grounds for further specific regulatory acts to have effect on commercial navigation on the waters of the route. The primary purpose of this article is to discuss the processes leading up to this long-awaited decision, as well as the implications of the new legislation for navigation on the NSR. The creative legal ambiguity of the Russian domestic legislation has historically allowed for divergent arguments, voiced by Russian scholars, in respect to the assumed legal basis for the Russian extended authority to regulate navigation on the NSR and the limitations thereof. Alternative views have provided grounds for different legislative proposals and for heated discussions leading to the adoption of the most recent law. This article will trace the development of the legal thinking in Russia with respect to the allocation of jurisdiction on the NSR.Keywords: Northern Sea Route (NSR) and legislation, new NSR law, NSR navigation, Article 234 of UNCLOS, Russian law, Russian ArcticCitation: Arctic Review on Law and Politics, vol. 4, 1/2013 pp. 90–119.

The legal basis of Sami reindeer herding rights in Sweden
Authors: Torp Eivind
Published: September 2023

This article discusses the basis of the Sami right to pursue reindeer herding, and how that right has been regulated in law. Two aspects of this right are particularly significant: establishing which land areas are covered by the reindeer herding right and clarifying what the right entails. The legal institution of ‘immemorial prescription’ has long been considered highly significant in judicial trials concerning the reindeer herding rights. In the wake of a ruling by the Swedish Supreme Court, that picture has now changed.Keywords: Sami reindeer herding, customary law, immemorial prescription, occupation, Swedish Supreme Court.Citation: Arctic Review on Law and Politics, vol. 4, 1/2013 pp. 43–61.

Decolonization and Canada’s ‘Idle No More’ Movement
Authors: Li Xiu Woo Grace
Published: September 2023

Canada’s ‘Idle No More’ movement ignited over concern about Prime Minister Stephen Harper’s abuse of majority status to enact laws that undermine democratic rights and environmental protection. With a philosophy that corresponds to international human rights principles, the movement galvanized public opinion and forged stronger alliances with the settler population. Ironically, Indigenous peoples are currently better situated than Canadians to challenge the lack of public consultation and violation of democratic principles that have come to light. The Supreme Court of Canada has recently confirmed that there is a duty to consult aboriginal peoples on issues that affect their rights, and several court actions have now been mounted on this basis. The goal of correcting endemic injustices and reinvigorating democracy will require a full re-evaluation of Canada’s colonial past and of the institutional format used to dispossess Indigenous peoples. Idle No More’s iconic flash-mob round dances suggest there is a new generation ready to take on this challenge.Keywords: British colonialism, monarchy, democracy, Indigenous, law, rights, sovereigntyCitation: Arctic Review on Law and Politics, vol. 4, 2/2013 pp. 181–206.

Fisheries in coastal Sami areas: Geopolitical concerns?
Authors: Smith Carsten
Published: September 2023

This paper aims to analyze the fishing rights of the Sea Sami (Coastal Sami) based on international law, particularly with respect to differing views in the recommendations of the Coastal Fishing Commission 2008, and in the Government bill 2012. The main point of international law discussed is the protection of the culture laid down in UN Covenant on Civil and Political Rights article 27. There is agreement to a large extent regarding the interpretation of this article. The paper intends to delimit the area of opposing arguments in order to define any future legal battleground. The author finds that the Government bill is unsatisfactory with regard to its legal reasoning. This international law issue has, in his opinion, such wide cultural implications that the discussion ought to continue.Keywords: Fishing rights, Sea Sami culture, Coastal Fishing Commission, Government bill 2012, UN Covenant on Civil and Political Rights article 27.Citation: Arctic Review on Law and Politics, vol. 5, 1/2014 pp. 4–10.

Husbandry and Productivity of Red Maasai Sheep in Arumeru and Monduli Districts in Tanzania
Authors: Chang'a Edwin P. , Kifaro George
Published: September 2023

This study was undertaken to describe the husbandry practices and productivity of the Red Maasai sheep in Arumeru and Moduli districts in Tanzania. Sixty three farmers from each of the two districts were interviewed. Data were analysed using SPSS computer package. All farmers (100%) practice an extensive production system where sheep graze together with cattle and goats. The majority (61.9%) of the farmers use communal land to graze their animals, and children are the main source (69.0%) of labour. Almost half (50.8%) of the farmers indicated to supplement their sheep with mainly (65.6%) maize bran. Identified constraints to production were diseases, drought, lack of capital, poor markets and extension services, thefts, and predators. A plastic apron was found to be an effective indigenous technique to control mating and practice seasonal breeding. Age at first lambing for the majority of Red Maasai sheep was 13 to 18 months and lambing intervals of 12 to 18 months. Most sheep lambed between October and January. Twinning cases were few (15.9%) indicating a low twinning rate in the population. Breeding rams were selected within flocks, and many farmers (95.2%) preferred seasonal breeding to allow ewes to lamb in the wet season. Disposals were done to get income, remove infertile ewes, and slaughter for food and rituals. Generally, the productivity of Red Maasai sheep was low due to poor husbandry practices. It was concluded that improved management was likely to enhance sustainable production and conserve the breed.

Authors: Mahendra I Nyoman Bayu , Budiana I Nyoman Gede , Jaya Made Suyasa , Putra I Gede Mega , Sanjaya I Nyoman Hariyasa , Taufiq Musa
Published: September 2023

Cervical cancer is a disease characterized by the growth of abnormal cells in the cervical tissue. Cervical cancer is mostly caused by Human Papillomavirus (HPV) types 16 and 18. The role of genetic factors in the development of cervical malignancy is mediated by the presence of a mutation in the HPV 16 oncogene, especially oncogenes E6 and E7. Oncogenic proteins E6 and E7 in HPV initiate dysregulation of cellular proliferation and apoptotic mechanisms by targeting tumor suppressor proteins, such as the p21 protein. The purpose of this study was to assess the association between mutations in the E6 and E7 oncogenes of HPV-HR Type 16 and the pattern of p21 protein expression. This cross-sectional study was conducted at the Obstetrics and Gynecology Polyclinic of Prof. Dr. I.G.N.G. Ngoerah Hospital, from September 2020 to September 2021. The material taken was cervical cancer tissue from cervical cancer patients and then put into a preservative solution and then put in a cooler. DNA isolation was performed, and PCR was performed to determine positive and negative HPV. The amplification of the E6 and E7 genes was carried out before the sequencing and analysis of the E6 and E7 gene mutations was carried out. Then, immunohistochemical staining of p21 was carried out, followed by data analysis using SPSS for windows version 22.0. There were no significant differences in characteristics between the two groups. There was no association between mutations in the E6 and E7 HPV Type 16 oncogenes with p21 protein expression in cervical cancer cases (p-value 0.22).

Authors: Utomo Martin Prayiggo , Vitraludyono Rudy , Yupono Karmini
Published: September 2023

Tetralogy of Fallot (TOF) is a congenital heart condition characterized by right ventricular hypertrophy, pulmonary stenosis, aortic overriding, and ventricular septal defect. Its presence raises mortality and perioperative risk. Noncardiac abnormalities associated with this condition include neurological, musculoskeletal, and ophthalmological defects, all of which were present in the index case. The complexity of the heart lesion, coupled with individuals' potential to compensate, the urgency of the operation, and numerous concurrent conditions all present challenges for anesthesiologists when dealing with patients with cyanotic congenital heart disease (CHD) who require extracardiac surgery. The objectives of anaesthesia in patients with ToF are to minimize pulmonary vascular resistance (PVR), maintain or raise systemic vascular resistance (SVR), and prevent intraoperative hypercyanotic episodes. To investigate a case report in neonates with tetralogy of Fallot and discuss further anaesthesia perioperative management in laparotomy procedure in neonates with tetralogy of Fallot (ToF). A 20-days female neonate, weighing 1,9 kg, was referred to our hospital with the diagnosis of high-level bowel obstruction et causa suspect atresia duodenum dd duodenal stenosis, tetralogy of Fallot (ToF), and a Secundum Atrial Septal Defect (ASD) with ASA IV. The patient was planned to undergo general anaesthesia for explorative laparotomy surgery. There were hemodynamic changes during surgery, but they can be appropriately managed. Anaesthesia and surgery were successful, and the patient improved. Preoperative, Durante-operative, and postoperative management was shown. Tetralogy of Fallot (TOF) Children generally have congenital heart defects. Preoperative planning, managing anaesthesia during surgery, and typical postoperative problems in the critical care unit are all perioperative considerations. The procedure will be completed successfully with the help of careful planning and a solid understanding of physiological and pharmacological principles.

Authors: Solovyova JuV
Published: September 2023

Currently, there are many problems with the reproductive health of schoolchildren, which can have an adverse effect on the future generations. This article overviews the current papers highlighting the most common problems that negatively affect reproductive health. The key conclusions include statements of the existing problems and suggested measures to counter them. Statements: as a rule, schoolchildren lack sufficient knowledge and skills in the field of reproductive health; often, they do not know the physiological characteristics of their body or cannot navigate them, do not recognize what is normal and what is not in the context of the age-driven development of the body. Measures: educational establishments need to develop and implement preventive measures and programs aimed at teaching schoolchildren the correct reproductive behavior.

La necesidad de un nuevo tipo delictivo: La desinformación como una amenaza para el orden público
Authors: Marchal González Adrián Nicolás
Published: September 2023

El fenómeno de la desinformación ha estado presente a lo largo de la historia, pero el principal problema en la actualidad es su “democratización”, pues el acceso constante a redes sociales y aplicaciones de mensajería instantánea hacen que las noticias falsas tengan una repercusión e impacto nunca antes visto, y un único usuario, desde su dispositivo móvil, es capaz de llegar a cientos de personas. Esta acción de desinformación antiguamente solo podía hacerse por instituciones u organizaciones con mucho poder, mientras que en la actualidad con herramientas como las mencionadas puede desinformar cualquier persona. Ello origina en algunos casos un grave ataque a la veracidad de los hechos, lo que provoca la distorsión de la realidad en la población y la desconfianza en las instituciones oficiales, lo que, en definitiva, altera la paz social y la convivencia pacífica de una sociedad. Por todo ello, en el presente artículo se estudia la posibilidad de tipificar un nuevo delito que incluya la desinformación, como una respuesta alternativa y efectiva ante dicha amenaza.

Published: September 2023

La disrupción digital ha revolucionado muchos aspectos de la vida, incluyendo el proceso de contratación de personal. En este nuevo contexto, se ha producido una transformación significativa en la forma en que las empresas seleccionan a los candidatos para sus puestos de trabajo. En lugar de depender exclusivamente de currículos en papel, ahora se utilizan plataformas y sistemas inteligentes basados en internet para analizar los perfiles de los aspirantes de manera rápida y eficaz. Este enfoque proporciona una selección más objetiva y eficiente para las empresas, lo que les permite identificar a los candidatos más adecuados para el puesto de trabajo. No obstante, la rápida y masiva aplicación por empresas de dichas inteligencias artificiales ha generado un contexto sin precedentes, una tierra de nadie desde la perspectiva jurídica, que escapa al control de las leyes y dificulta su regularización.

Published: September 2023

The present study was conducted in the isolated desert town of Oranjemund in the far south of Namibia. It is an extremely arid region where no livestock husbandry is practiced and only animals adapted to the desert can be found. However, in and around the city, artificial irrigation maintains lush green patches of grass that attract wild animals, in particular oryx antelopes (Oryx gazella). In 2015 four oryx antelopes were euthanised due to poor conditions and a post-mortem examination was conducted. Two were found positive for cystic echinococcosis and 16 cysts were collected for molecular analyses. In addition, faecal samples from black-backed jackals (n=5) and domestic dogs (n=9), which were regularly observed to feed on oryx carcasses, were collected and taeniid eggs isolated. Parasite species identification of the cysts and eggs was done by amplifying and sequencing the mitochondrial nad1 gene. Both oryx antelopes were found infected with E. ortleppi and one co-infected with E. canadensis G6/7. Both Echinococcus species were able to develop fertile cysts in oryx, making oryx antelopes competent hosts for these parasites. Therefore, the analysis of faecal samples was of high interest and although the numbers were quite small, taeniid eggs were found in three out of five faecal samples of jackals and in all nine dog samples. However, species determination was only successful with two jackal and one dog sample. All three were positive for E. canadensis G6/7. The absence of E. ortleppi may be due to the low number of faecal samples examined. In our small study, we discovered a rather unique lifecycle of Echinococcus spp. between jackals and domestic dogs as definitive hosts and oryx antelopes as intermediate hosts. Here, the presence of E. canadensis G6/7 is of particular concern, as it is the second most important causative agent of CE in humans.

Published: September 2023

Helminth infection was analysed at necropsy and coprology in a total of 54 roe deer from the province of Grosseto (central Italy) between 2018 – 2020. Age and sex data were recorded for each deer for a total of 31 adults (23 females, 8 males) and 23 juveniles (11 females, 12 males).

The results on the small intestine (51 samples) highlighted that nematodes belonging to the species Trichostrongylus colubriformis were the most prevalent parasite (41.2 %), followed by the cestode Moniezia expansa (7.8 %). The large intestine results (52 samples) showed Trichuris spp. (53.8 %), Oesophagostomum venulosum (50 %) and Chabertia ovina (26.9 %). In the abomasum, only Ostertagia ostertagi (17.9 %) was found. Of the 34 samples analysed by bronchopulmonary, only the lung of an adult female was positive for Dictyocaulus spp. In two livers out of 33 samples analysed, nematodes of the species Setaria tundra were found on the surface. Copropositivity was observed in 45 of the 52 faecal samples analysed. The results of the present study indicate that the roe deer is host to several species of parasites, which are also common in other cervids and domestic ruminants. Statistical testing highlighted a significant difference between mean intensities in males and females.

The objective of this study was to determine the risk factors and prevalence of trematodes in south-eastern Mexico. The prevalence of trematodes was determined in 1010 bovines. The study was carried out from October 2018 (n=291) to December 2019 (n=719). Only in 2019 rumen and liver fluke eggs were differentiated. Faecal samples (n=311) were obtained from farms in southeast Mexico located in Tabasco, Chiapas and Campeche. In addition, the presence of flukes in liver and rumen from slaughtered cattle in abattoirs was recorded with a total of 408 samples. A logistic procedure was used to obtain the prevalence and the effect of main risk factors such as land physiography (flooded areas and hills), year, sex, animals’ age and type of sample obtained (eggs in faeces and flukes). The general prevalence of flukes in cattle was 32.3 % in 2018 and 41.7 % in 2019. Prevalence of F. hepatica (liver fluke) was 18.6 % (134/719) and that of paramphistomids (rumen fluke) was 33.4 % (240/719). The infected cattle from the slaughterhouse indicated a lower prevalence of F. hepatica (1 %) and rumen fluke (26.7 %) than in farms detected by egg in faeces (41.8 % and 42.1 %, respectively). The physiographic zone was decisive in the presence of F. hepatica and rumen fluke, while sex did not represent a risk factor (P > 0.05). The environmental conditions of the Mexican southeast favour the presence of both liver and rumen fluke.
Nematicidal effects of silver nanoparticles (AG-NPs) on the root-knot nematode, Meloidogyne javanica associated with Swiss chard (Beta vulgaris L.)
Authors: Daramola F. , Lewu N. , Nkiko J. , Lewu F.
Published: September 2023

Root-knot nematodes (RKNs) are important nematode pests, causing huge economic losses on vegetable crops worldwide. A decline in the yield of Swiss chard (Beta vulgaris L.) which was associated with RKNs was observed on an organic vegetable farm in the Western Cape Province of South Africa. Nematodes were extracted from galled plant roots and identified using molecular tools. PCR-based Sequence Characterised Amplified Region (SCAR) primers was used to confirm the specie of the RKN associated with the infected plants. Thereafter, a pot assay was conducted to determine the response of artificially infected Swiss chard plants to varying concentrations of bio-synthesized silver nanoparticle Ag-NP (1 μg/mL, 2 μg/mL, and 3 μg/mL) under controlled conditions. The results of the study showed that Swiss chard is highly susceptible to M. javanica with an egg-laying-female index of >5 in all infected plants. Significantly lower values (at P=0.05) in egg masses (EM), juveniles (J2s), and reproduction factor (RF) of nematodes were recorded on plants treated with 3 μg/mL, indicating a potential for nematode control. A negative correlation was also observed in the number of egg masses, J2s, and RF of the nematodes with increasing concentrations of the Ag-NP. This study confirms that Swiss chard is highly susceptible to M. javanica and demonstrates the potential nematicidal property of Ag-NP in controlling the nematode pest of Swiss chard.

Published: September 2023

The helminth fauna of juvenile green sea turtles (Chelonia mydas Linnaeus, 1758) is still poorly known. Herein, we study the gastrointestinal helminths of 28 juvenile green sea turtles found stranded on the north coast of Rio de Janeiro state, Brazil. All turtles were infected showing a rich helminth fauna. In total, 14802 trematodes belonging to 30 species and 5 families including Micros-caphidiidae, Plagiorchiidae, Pronocephalidae, Hapalotrematidae, and Telorchiidae were recovered. An unidentified nematode specimens was also found. The mean intensity was 536 (95% CI = 362 – 853) (range: 1 – 2831), and the species richness was 7.86 (95% CI = 6.46 – 9.21) (range: 1 – 17). The coast of Rio de Janeiro state represents new locality records for Angiodictyum posterovitellatum, Microscaphidium aberrans, M. warui, Octangium hyphalum, O. sagitta, Enodiotrema reductum and Pleurogonius laterouterus. This study confirms that the green sea turtle harbors the richest helminth fauna among sea turtle species and provides useful information on the gastrointestinal helminths of a poorly known stage in the life cycle of this endangered chelonian.

Published: September 2023

Variables and expressions serve as bridges where students cross from arithmetic to algebra. Although variables and expressions are important concepts in middle school and high school mathematics, they are topics that many students find challenging, and many, in fact, do not develop a thorough understanding of these topics. This study aims to explore the epistemological obstacles students face in understanding and interpreting the concepts of variables and expressions. Based on these objectives, a qualitative research design with a phenomenological approach was chosen to achieve this research objective. The subjects in this study were 8th grade middle school students in the city of Medan, Indonesia. Tests and interviews were used to collect data. The data obtained were analyzed using an inductive approach. The data obtained are presented in narrative and graphical forms. Based on the research results obtained, six types of student errors in solving problems related to the concept of variables and expressions were identified. Overall, students' limitations in understanding and interpreting variables as something unknown is one of the triggers for epistemological obstacles. Teachers should give chances for pupils to debate and explain variables and expressions in the classroom to assist students gain a comprehensive knowledge of these mathematical tools.

Published: September 2023

During the Covid-19 pandemic, the implementation of online and shift learning systems has been identified as one factor contributing to learning loss in mathematics problem-solving skills specifically in plane geometry problems. The primary objective of this research was to investigate the different types of errors committed by junior high school students in Banda Aceh, Indonesia, in solving plane geometry problems using e-learning diagnostic tests. A descriptive qualitative approach was adopted, and 24 Year 8 students were selected as subjects. The data were collected through tests and interviews, and data analysis involved data reduction, data presentation, data verification, and drawing conclusions. The findings revealed that the percentage of students' errors in solving conceptual problems, principal problems, and verbal problems were 76.39%, 68.75%, and 75%, respectively. Subsequently, the results from the second test and interviews with six students showed that students encountered several conceptual errors, including errors in stating angle symbols, errors in identifying the type of shape provided, errors in deducing information regarding properties, perimeter, and area of plane geometry, lack of knowledge regarding the application of the appropriate plane geometry formula, and inability to solve problems using the correct procedure. Principal errors were related to algebraic operations, while verbal errors involved translating problems and improper application of concepts and principles. The understanding of the types of errors will help teachers detect errors made the students early.

Dimana menjelang bulan ramadhan harga buah melon akan meningkat dari Rp. 15.000,- menjadi Rp. 18.000,-. Distribusi buah melon segar sebagian besar adalah ke Rumah Sakit Umum Zainal Abidin dan beberapa pasar lainnya. Kualitas buah melon dikategorikan sangat baik dan tinggi vitamin A sehingga layak di konsumsi oleh orang yang sehat dan dapat menyembuhkan penyakit degenerasi makula atau penurunan fungsi penglihatan. Kegiatan pengabdian pada masyarakat ini dilaksanakan dalam bentuk praktik langsung dengan metode konvensional dan hidroponik fertigasi sederhana dimulai dari cara pembibitan, penanaman, perawatan dan pemanenan, sehingga menghasilkan target luaran buah melon dengan kualitas terbaik. Kualitas buah melon dengan metode hidroponik menghasilkan berat buah hanya 0,5 kg perbuah, namun dengan metode konvensional sangat baik yaitu ditandai dengan tebal daging buah dan bobot buah rata-rata 2,5 kg - 4 kg per buah. Oleh karena itu dapat disimpulkan bahwa kegiatan budidaya buah melon mampu memberikan banyak manfaat dalam peningkatan pemanfaatan lahan serta pengetahuan untuk budidaya buah melon secara konvensional dan hidroponik.

Peningkatan jumlah wirausahan muda di bidang peternakan merupakan tugas utama perguruan tinggi yang dapat dilakukan dengan pembinaan calon kader sejak masa perkuliah sampai kepada alumni. Usaha bisnis dibidang perunggasan tergolong sangat diminati karena permintaan konsumen akan produk unggas, baik daging, telur bahkan bibit semakin meningkat. Salah satu produk perunggasan yang mulai dikenal masyarakat yaitu ayam hibrida yang merupakn ayam hasil persilangan ayam lokal dengan ayam layer dan jenis ayam unggul yang berasal dari luar negeri. Ayam hibrida sangat potensial dikembangkan sebagai turunan ayam lokal yang mampu menghasilkan telur lebih banyak dan ukuran telur lebih besar dibandingkan telur ayam aslinya. Namun dalam proses pengembangannya diperlukan upaya dukungan dibidang pembibitan sehingga permintaan akan bibit ayam hibrida dapat dipenuhi untuk mendukung usaha komersial. Untuk itu telah dilakukan kegiatan pengabdian kepada masyarakat dalam bentuk penyuluhan dan demontrasi langsung kepada 16 orang kader wirausahaan pembibitan unggas yang berasal dari siswa SMK, mahasiswa peternakan dan alumni peternakan dengan tujuan untuk peningkatkan kemampuan manajemen usaha pembibitan ayam hibrida lokal. Kegiatan ini berjalan selama 30 hari dengan pembekalan 4 materi utama dan demonstrasi berupa teknis perkawinan inseminasi buatan, seleksi telur tetas, pembuatan mesin tetas dan proses penetasan sampai pada seleksi jenis kelamin DOC hasil penetasan. Hasilnya menunjukkan bahwa 94% peserta berada pada katagori sangat menguasai materi yang diberikan dan 87,5% sangat menguasai kegiatan demonstrasi yang telah diberikan oleh tutor kegiatan. Sementara itu 6% peserta menguasai materi dan 12,5% peserta lainnya juga katagori menguasai kegiatan demonstrasi yang diberikan. Melalui hasil survei kepuasaan peserta menunjukkan bahwa seluruh peserta (100%) menyatakan sangat puas terhadap materi dan kegiatan demonstrasi pelatihan dan merasakan manfaat yang sangat besar terutama sebagai wawasan baru dibidang usaha peternakan. Peserta menyarankan agar dimasa yang akan datang, lama waktu pelatihan diperpanjang menjadi 3 bulan dan mencakup juga untuk jenis unggas lainnya seperti itik dan puyuh.

Published: September 2023

Objetivo: evaluar el impacto económico, social y ambiental de los programas sociales (PS) implementados en tres comunidades rurales de la Mixteca en Oaxaca. Metodología: se hizo uso de la entrevista semiestructurada, recorridos de campo y diálogo directo. En una muestra de 60 beneficiarios de los diferentes programas sociales que operan en la microrregión Teposcolula, Resultados: existe correlación entre los años que las personas llevan participando en los programas con la migración familiar y con la equidad de género a nivel local. Se encontró una dependencia entre los apoyos recibidos en el PS en relación con la localidad y el nivel de apoyo que considera recibir en el PS. En relación al medio ambiente, se han implementado sistemas agroforestales para la producción de alimento familiar. Limitaciones: por tratarse de información de los programas sociales, los beneficiarios desconfían de las instituciones y temen que la información proporcionada afecte su nombre y su inclusión en el programa. Conclusiones: los PS evitan la migración, aumentan la equidad de género y el acceso a servicios de salud. Mediante los ingresos generados los beneficiarios compran alimento y pagan servicios básicos de su vivienda Los diferentes programas productivos han contribuido a generar acciones que contribuyen a contrarrestar la contaminación de su medio ambiente.
Design of an innovative self-compacting material modified with recycled steel fibers and spent equilibrium catalyst for ultra-high performance applications

Published: September 2023

The main aim of the present study is to design an innovative self-compacting material modified with recycled steel fibers (RSF) from waste tires and spent equilibrium catalyst (Ecat) from the petrochemical industry for ultra-high performance application. For this purpose, 17 different mixtures were developed and analysed using different percentages of RSF (0%-3%) and replacement of cement by different percentages of Ecat (0%-15%).

The developed mortars' self-compatibility was evaluated in a fresh stage using mini-cone tests. Regarding the hardened stage, the mortars were characterized at the ages of 7 days and 28 days using compression and unnotched flexural tests. The abilities of RSF to increase the post-cracking behavior of the specimens and to use Ecat to increase the bond performance between RSF and the cement matrix were assessed by performing notched three-point bending tests. The results of notched flexural tests were used to obtain the residual flexural strength in service limit state (SLS), ultimate limit state (ULS), and two equivalent flexural strengths.

The experimental results for the fresh stage demonstrated that inclusion of RSF and Ecat significantly reduced the workability of mortars. The beneficial use of RSF and Ecat was observed to increase compressive strength and flexural strength for 7 days and 28 days of tested specimens. Notched flexural tested specimens showed that the addition of RSF and Ecat can significantly decrease the brittle behavior of cement-based materials by improving its toughness and post-cracking resistance. Middle-span deflection, crack initiation load, and ultimate flexural load were also increased with the addition of RSF and Ecat. In this sense, the results of this research showed that RSF and Ecat seem to have the potential to constitute a sustainable material for structural and nonstructural applications.
Dynamic effects on the lattice boom crane due to the wind, moving load and earthquake events
Authors: Solazzi Luigi , Danzi Nicola
Published: September 2023

The present research concerns the evaluation of the dynamic effect on lattice boom cranes. The dynamic actions involved in this research are: wind, moving load and earthquake, assumed as time-varying actions. The research starts with the design of a large crane by adopting classical standards for these structures (UNI EN 13001 series). The elaborations were performed by analytical methods followed by solid model building and finite element analysis (Solidworks® and Ansys® software). The next step was to define the aforementioned loads acting on these structures.
The wind action model was compared with the static approach. Payload displacement induces high-intensity actions on the crane structure; to better understand these effects, several load curves were simulated. The last action considered is the earthquake phenomenon, which is not usually adopted to design this type of structure.
Проблемы имиджевого позиционирования и информационного продвижения экономического и гуманитарного сотрудничества Дальнего Востока России со странами Юго-Восточной Азии
Authors: САМОЙЛЕНКО Петр Юрьевич
Published: September 2023

В статье рассматриваются актуальные проблемы развития экономического и гуманитарного сотрудничества российского Дальнего Востока со странами Юго-Восточной Азии на современном этапе. Автор уделяет внимание таким проблемам, как развитие полноценного торгово-экономического сотрудничества и инвестиционных проектов на Дальнем Востоке России с участием экономик АСЕАН, перспективам и проблемам имиджевого позиционирования и продвижения такого сотрудничества и регионов российского Дальнего Востока в Юго-Восточной Азии. В качестве типичного примера рассматриваются отношения России и Вьетнама как одного из государств ЮВА, традиционно тяготеющего к сотрудничеству с нашей страной, отношения с которым в настоящее время имеют тренд к новой фазе постепенного развития и сотрудничества. В статье отмечается,что экономическое, деловое и гуманитарное сотрудничество помимо своих непосредственных целей также может увеличивать и общее влияние России в Юго-Восточной Азии, которое на сегодняшний день остается явно недостаточным для развития современной российской политики "Разворота на Восток" и обеспечения национальных интересов в пределах всего Азиатско-тихоокеанского региона.
