SANCTIONS FOR ANNULMENT OF MARRIAGE IN THE CUSTOMARY LAW OF THE PEKANBARU MALAY COMMUNITY
Authors: Juswandi  , Akbarizan
Published: February 2023

The betrothal is conducted before the traditional marriage ceremony is carried out. Betrothal is commonly called an engagement or application process carried out by the male party to the female side. This research was conducted to determine the sanctions in the customary law of the Malay community that apply if one of the bride and groom's parties cancels the betrothal agreement and how the law is carried out. The research uses qualitative methods that are descriptive analysis. This study uses Schleiermacher's romantic hermeneutics, which is a text analysis approach. Based on the results of the research discussion, it can be concluded that the Malays uphold the rules and laws of Islamic sharia in marriage. In this study, there are two versions of customary sanctions adopted by the Malay community. The customary sanction applied in Kuantan Singingi Regency, Kuantan Hilir Seberang District, regarding the annulment of marriage is the agreement of both parties to provide a number of materials to one of the aggrieved parties so that there is no misunderstanding. This sanction is carried out in order to have a deterrent effect on the party who breaks the promise or cancels the marriage.
Analisis Putusan Pengadilan Federal Australia atas Kasus Montara dan Implikasinya terhadap Sengketa Pencemaran Laut Lintas Batas di Masa Depan
Authors: Juariah Rini Siti
Published: February 2023

Kasus Montara 2009 telah menyebabkan kerugian bagi sekitar 15.000 petani rumput laut di NTT. Pada 2021, Pengadilan Federal Australia memutus PTTEP Australasia bersalah dan diwajibkan membayar ganti rugi. Pertimbangan Hakim adalah ia yakin tumpahan minyak Montara memang sampai ke Rote/Kupang dan secara material berkontribusi atas rusaknya rumput laut. Hakim menemukan PTTEP Australasia memiliki duty of care terhadap para korban yang justru dilanggar. Putusan ini berpotensi menjadi preseden bagi kasus-kasus pencemaran laut lintas batas, memicu lebih banyak gugatan class action lingkungan, dan menunjukkan kebutuhan membentuk konvensi internasional terkait kompensasi kerugian akibat pencemaran yang disebabkan bisnis minyak lepas pantai.
Konsep Ummī Dalam Al-Qur’an
Authors: Gusti Gusti Rahmat , Ghaffar Abdul , Abbas Pirhat
Published: February 2023

Artikel ini mengkaji sejarah pemaknaan lafaz ummī pada awal kemunculannya serta pemaknaan lafaz ummī dari segi kebahasaan dan pemaknaannya di masa kini dan bagaimana konsepsi al-Qur’an tentang lafaz ummī. Penelitian ini adalah penelitian kepustakaan dengan teknik deskriptif analitis. Hasil dari penelitian menunjukkan tiga hal penting antara lain; pertama, kosa kata ummī dalam al-Qur’an jika dilihat dari konteks historis, maka ayat-ayat yang memuat lafaz ummī tidak memiliki asbāb al-nuzūl secara khusus. Kedua, kosa kata ummī dalam analisis eiditik (kajian kebahasaan), sebenarnya telah ditafsirkan dengan banyak makna otentik yang diperluas dan dikembangkan oleh para generasi sahabat, tabi’in, tabi’ tabi’in, dan ulama-ulama setelahnya hingga saat ini. Ketiga, terma ummī dalam konteks analisis praksis mengarah pada makna yang diberikan oleh hermeneutika modern yang berusaha menyatukan makna-makna tekstual linguistik dengan makna kontekstual historis, kemudian mensinergikan keduanya dengan makna al-maghzā untuk menemukan makna relevansinya yang sesuai dengan konteks sosial budaya, yang dapat diterima masyarakat di berbagai tempat, dan sejalan dengan situasi dan kondisi kekinian di mana dan kapan kata ummī didialogkan dan diinterpretasikan.

POTENTIAL USE OF SOME PLANT EXTRACTS AND ESSENTIAL OILS TO CONTROL GREATER WAX MOTH, Galleria mellonella LINNAEUS AND ITS SELECTIVITY IN RELATION TO HONEY BEES
Authors: NISHANTHINI K. , KANAGARAJAN R.
Published: February 2023

The use of synthetic insecticides is one of the most widely used strategies to control wax moth infestations. However, toxicity to bees and contamination of their products have been considered to be consequences of insecticide residues, increasing the risk of hazards to human health and environment. Here, we evaluated the application of plant extracts and essential oil would be selective against the honey bees Apis cerana indica L. without compromising the control of the wax moths Galleria mellonella. In that, peppermint oil (1.25%) and Azadirachta indica (3%) caused 53.33% and 40.00% mortality. Whereas, eucalyptus oil (1.25%), Ocimum tenuiflorum (3%) extract caused 33% wax moth mortality. But in contact toxicity, peppermint oil and eucalyptus oil (5%) caused highest larval mortality 80% and 72.38%, O. tenuiflorum at 10% concentration recorded 56.19% mortality. In repellence bioassay, peppermint oil (1.25%) and A. indica (3%) caused 100% repellence. Whereas, at 10% concentration only O. tenuiflorum caused 100% repellence. Furthermore, O. tenuiflorum (10%), A. indica (10%), peppermint oil (2.5%) and eucalyptus oils (2.5%) did not kill honeybee but did exhibit insecticidal and repellent activities against the larvae and adults of wax moth. By exhibiting desirable levels of selectivity against A. cerana indica and providing relevant control levels against wax moths, the application of O. tenuiflorum leaf extracts and pepper mint essential oil represents a desirable tool to replace the use of synthetic insecticides against wax moths in weak honey bee colonies as well as in stored honey bee combs.

A Yellowstone Nemzeti Park 1872-es megalapítása óta világszerte nagy számú védett természeti terület került kijelölésre. Az IUCN a területek többségét regisztrálta, azonban a nyilvántartásban olyan egyedi típusú védett területekkel is találkozhatunk, mint a zapovednikek és a zakaznikok. Mindkét területtípus a volt Szovjetunió területén fordul elő. Az IUCN 1998-as összesítése alapján 1997-ig 130 zapovedniket jelöltek ki Oroszországban (91), Azerbajdzsánban (12), Kazahsztánban (8), Türkmenisztánban (8), Kirgizisztánban (6), Tádzsikisztánban (3) és Fehéroroszországban (2). A zapovednikek olyan védett természeti területek, amiket azért alapítanak, hogy menedéket nyújtsanak élőhely-specifikus ritka állatfajoknak, mint például Barguzini Zapovednikben élő coboly (Martes zibellina), vagy a Kedrovaya Pad Zapovednikben élő amuri leopárd (Panthera pardus orientalis). Az IUCN ezeket általában Ia típusú területeknek minősíti, vagyis szigorúan védettek. A zapovednikeket tehát azért hozták létre, hogy olyan érintetlen ökoszisztémával rendelkező mintaterületek legyenek, ahol lehetőség van természetvédelmi kutatásokra. A zakaznikok kijelölésének célja eltérő. 1997-ig 259et alapítottak belőlük: 83-at Oroszországban, 59-et Kazahsztánban, 53-at Fehéroroszországban, 20-at Kirgizisztánban, 17-et Azerbajdzsánban, 14-et Tádzsikisztánban és 13-at Türkmenisztánban. A „zakaz” szó tiltást jelent és a természetes erőforrások használatának részleges vagy teljes, előre meghatározott idejű korlátozására utal. Eredetileg azért alapították őket, hogy zavartalan szaporodási lehetőséget biztosítsanak a vadászható állatfajok számára, manapság azonban a specifikus zoológiai, botanikai, hidrológiai és geológiai értékek védelme az elsődleges céljuk. A zakaznikokat az IUCN rendszerint IV típusú védett területeknek minősíti, melyek különleges természetvédelmi kezelést igényelnek egy adott veszélyeztetett faj vagy élőhely megóvása érdekében.
Spontán erdőállományok fafajösszetételének áttekintő értékelése az Országos Erdőállomány Adattár alapján
Authors: Zagyvai Gergely
Published: February 2023

A kutatás során a spontán eredetű erdők fafajösszetételét elemeztem az Országos Erdőállomány Adattárban „talált” erdőként nyilvántartott állományok adatai alapján. Erdészeti tájanként értékeltem a spontán erdők faállománytípusait. A fafajokat országos és táji szinten hasonlítottam össze a területük, a területükből számított változók, valamint a terjedőképességet és a terjedési lehetőséget leíró TSI index alapján. A legfontosabb fafajok egymáshoz képesti viszonyát sokváltozós statisztikával elemeztem. A spontán erdők nagysága és összetétele jelentős táji változatosságot mutat. A tájak nagy többségében a spontán erdősülő területek az inváziós terjedés színterei [elsősorban fehér akác (Robinia pseudoacacia)]. Az inváziós kockázat mellett, a Dunántúl délnyugati és az Északi-középhegység keleti részén mutatkozik reális lehetőség nagyobb területen, őshonos fafajokkal, diverz módon történő regenerációra. A spontán erdők fajösszetétele jelzi a kocsánytalan tölgy szerepének csökkenését a csertölgyéhez képest. Egyes honos r-K stratégista fafajok [pl. mezei juhar (Acer campeste)] spontán erdősödésben betöltött jelentősebb szerepe természetvédelmi szempontból is előnyös alternatívát kínál a középtávon visszaszoruló honos pionír és az inváziós fafajokkal szemben. Egyes adventív fafajok [pl. ezüst juhar (Acer saccharinum)] még nem tartoznak a legkártékonyabb özönfajok közé, de eredményeim szerint veszélyesebbé válhatnak és jelentősebb természetvédelmi problémát okozhatnak.

Napjainkra a különböző válságok következtében egyre inkább igény mutatkozik a természet által az embereknek nyújtott javak feltérképezésére, az ökoszisztéma-szolgáltatások kutatására. Feltételezésünk, hogy a természetközeli gazdálkodás segíti fenntartani azokat az élőhelyeket, melyek jó minőségben képesek az ökoszisztéma-szolgáltatások széles skáláját nyújtani. Vizsgálati mintaterületeink Gyűrűfű és Visnyeszéplak ökofalvak, ahol az emberi tevékenység már több évtizede a természettel összhangban működik, és a gazdálkodás szempontjából a tájpotenciálhoz igazodik. Kutatásunk során elemeztük az ökoszisztémák állapotát mindkét mintaterületen, valamint a települések ökoszisztéma-szolgáltatásait hasonlítottuk össze térképi, táblázatos és szöveges formában. Az adatgyűjtés és -elemzés során szakirodalmi művekre, térképi adatbázisokra, 8 interjúra és a Visnyeszéplakon elvégzett fészkelő-madárállomány felmérésre támaszkodtunk. Eredményeink azt mutatják, hogy a mintaterületeken az ökoszisztémák állapota rendkívül jó a tájszerkezet és a fajdiverzitás szempontjából is, de vannak veszélyeztető tényezők (talaj minősége, víz mennyisége), amelyek befolyásolják és némiképp negatívan is hatnak a gazdálkodásra. Összesen 12 ökoszisztéma-szolgáltatást azonosítottunk (külön-külön 11–11-et). Az ökoszisztéma-szolgáltatások száma alapján a visnyeszéplaki gyümölcsös élőhely bizonyult a legkiemelkedőbbnek, ezt követték a gyűrűfűi erdők és a visnyeszéplaki gyepek. Az eredmények alapján több különbség is látszik a két település ökoszisztémáinak állapotában és az élőhelyeik szolgáltatásnyújtó képességében. Fontos különbség a területek szerkezeti jellegének eltérése: amíg Visnyeszéplakon kiegyensúlyozottabb az élőhelyek eloszlása, addig Gyűrűfűn az erdő és cserjés, valamint a gyep élőhelyek dominálnak. Fontos eltérés még a két ökofalu között a gyümölcsösök kezelése, ami tetten érhető a gyümölcsösök ökoszisztéma-szolgáltatás nyújtó képességében is. Összességében ugyanakkor a két település az alapcélokban egyezik, ami leginkább hangsúlyosan járul hozzá adott ökoszisztéma-szolgáltatások jelenlétéhez és ahhoz, hogy a még potenciális szolgáltatások a jövőben realizálhatóak legyenek.
Potential carbon sequestration across Szentendre Island
Authors: Nel Lyndré , Masoudi Malihe
Published: February 2023

Land-use in Hungarian landscapes have generally seen a decrease in agricultural land and increases in uncultivated land cover and forestry. Such types of land-use change have a cumulative impact on the atmospheric carbon that can potentially be sequestered across a landscape. The transformation of natural vegetation into cultivated land-use types and cultivated into uncultivated types alter the operationality of soil carbon storage across a time scale. This study looks at the land-use change and soil carbon storage potential, as an ecosystem service, on the Szentendre Island (59 km2) in the Danube River, Hungary, in 1998 and 2018. Land-use and land-cover (LULC) and topsoil carbon storage in 1998 and 2018 were mapped with the InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) Carbon Storage and Sequestration Model. Current LULC data were matched with carbon pool data as inputs for the Carbon Model. The resulting maps present the potential carbon storage value of landuse types across the Island for 1998 and 2018. Over 20 years, Szentendre Island experienced changes in LULC; an increase in artificial surfaces, forests, and pastures, and a decrease in arable land, natural vegetation, and wetlands. Based on the land-use data, our result showed that potentially 736.97 Mg of carbon was stored in the topsoil (0–20 cm) of the Szentendre Island in 1998, compared to 737.33 Mg of carbon in 2018. In conclusion, consideration is given to the land-use change trends and the need for environmental impact assessments and programs that increase soil carbon storage for the highest level of potential carbon sequestration on Szentendre Island.
Városi tavak környezeti állapotértékelése Szeged példáján
Authors: Babcsányi Izabella , Bodor Dezső , Sipos György , Farsang Andrea
Published: February 2023

Szeged belterületén 15 kisebb-nagyobb tó található. Némelyek természetes eredetű vízjárta helyek, mások a XIX. század végén mélyített kubikgödrök, vannak azonban közöttük bányatavak és holtágak is. Öt szegedi tónak vizsgáltuk a környezeti állapotát, melyek közül a Bika-tó természetes eredetű, a Méntelepi Fehér-tó és a Búvár-tó sekély kubikgödrök (<3 m), a Csemegi-tó és a Sancer-tó mélyebb bányatavak (>10 m). Ezek közül három tóban vizsgáltuk évente megismételt vízmintákon (2009 és 2017 között) a víztér oldott oxigén-tartalmát, kémiai oxigén igényét (az oldott szerves anyagot), továbbá az oldott nitrogénformákat (nitrát, nitrit, ammónium) és az ortofoszfát-koncentrációt. A Sancer-, a Búvár- és a Bika-tavakban történt üledékmintavétel nehézfém-analízis céljából. A vizsgált városi tavakban jelentős a víztér szervesanyag- és N-, P- tápanyagterhelése. Vízminőségi adatok alapján megállapítható, hogy a tavak ammónium- és nitrát-koncentrációi némileg csökkenő tendenciát mutatnak az utóbbi években, amely összefügghet a tisztítatlan szennyvízbevezetések vélt csökkenésével. A város csaknem teljes csatornázottsága 2006-ra épült ki Szegeden, azonban a csatornákból szivárgó szennyvíz és a lassan regenerálódó szennyezett talajvíz továbbra is terhelheti a tavakat. Az oldott foszfát-koncentrációk azonban továbbra is magasabb értékeket mutatnak egyes tavakban, amely a korábban az üledékekben felhalmozott P kioldódásából adódhat. Ez történhet az üledékek szerves anyagainak lebomlásával, különösen anaerob állapot fellépése esetén. Az üledékvizsgálatok alapján megállapítható, hogy egyes jellemzően közlekedési eredetű nehézfémek (Cu, Zn, Pb) kisebb mértékű dúsulást mutatnak a felszíni üledékrétegekben a forgalmas utak mentén elhelyezkedő tavakban. Azonban egy nehézfém dúsulása sem éri el a jogszabályban lefektetett szennyezettségi határértékeket. Összességében megállapítható, hogy a vizsgált szegedi tavakat magas trofitási fok jellemez, amely a tavak külső és belső tápanyagterheléséből és a vizük frissülésének hiányából adódhat.
Reformation and heterogeneity – connection between cultural and environmental manifestation in three spatial regions
Authors: Fülöp Györk
Published: February 2023

The main aim of this explorative work is to study the connection between the spatial distribution of protestant population (religions affected by reformation) and the spatial heterogeneity of land cover. The empirical approach of the paper excludes any historical or cultural analysis. It is irrespective for the generating processes, and rather initiates a descriptive overview. The target is the relation, and the general quality of this relation between two basic factors of landscapes – forming effects out of social and natural sources – throughout a comparative case study. If the existence of this relation is objectively confirmed as results of this analysis, a future follow-up research shall investigate the existing causal relations and describes how the ecologically influential spatial structures of the landscapes are connected to social processes like the reformation. Recent study has an objective attitude to the descriptive analysis, and applies spatial statistic methods in NUTS 3 regions of three ‘study areas’: Hungary, Germany and Romania. The utilized input data was collected from the 2011 census and from the landscape indexing of low resolution multispectral satellite remote sensing data of MODIS satellite mission. The interpreted statistical results show a significant underlying background effect between the spatial heterogeneity and the spatial distribution of protestant citizens. The nature of this relationship is to be investigated in the future. The outputs of this study intends to show a direction for the explorative research by providing the first step-stones in the form of significant landscape indices, basic descriptive statistics and rough estimation of the strength of the underlying effect.
Renewable energy technologies in the Alpine landscape and local communities’ perception of change
Authors: Zanon Bruno
Published: February 2023

The article addresses the issue of social perception of landscape change connected to energy production from renewables, in an Alpine area. The Alpine regions have undergone extensive transformations in the last century, and energy has played a key role in socio-economic phenomena and in landscape change, because of the availability of oil products and the impact of hydroelectric plants. Currently, a variety of renewable energy technologies (RETs) are available, providing new opportunities for mountain areas but producing important effects on the landscape. Their use require a change in the frames of reference of the actors involved and a new perception of landscape values by local communities. The paper analyses how the insertion of RETs in the landscape of Trentino, in the Italian Alps, is impacting on the social perception. The methodology builds on the results of recent research conducted in the province of Trento on the perception of landscape characters. This allows identification of the values at stake when making use of a new technology in the open space, and analysis of how and why impacts are coherent with local communities’ perception of landscape. This analysis makes it possible to frame the crucial issues concerning use of such technologies in the Alpine landscape and to discuss how such a change is perceived, drawing some conclusions of general interest.

Published: February 2023

Let G be a graph with vertex set V (G) and edge set E(G).  For u ∈ V (G), NV (u) = {w ∈ V (G)|uw ∈ E(G)} and NE(u) = {e ∈ E(G)|e = uv,  for some  {| ∈  } { | ∈  } v ∈ V (G)}. A bijective function f : V (G) ∪ E(G) → {1, 2, 3, . . . , |V (G) ∪ E(G)|} is said to be a vertex-edge neighborhood prime labeling, if for u ∈ V (G) with deg(u) = 1, gcd {f (w), f (uw)|w ∈ NV (u)} = 1 ;  for u ∈ V (G) with deg(u) > 1, gcd   f (w) w     NV (u)   = 1 and gcd   f (e) e     NE(u)   = 1.  A graph which admits a vertex-edge neighborhood prime labeling is called a vertex-edge neighborhood prime graph. In this paper we prove Km,n Ⓢ K1, Wn Ⓢ K1, Hn Ⓢ K1, Fn Ⓢ K1 and S(K1,n) Ⓢ K1 are vertex-edge neighborhood prime graphs.
AN SVIQR EPIDEMIC MODEL FOR COVID-19
Authors: Verma Vijai Shanker , Kunwar  Laxman Bahadur , Bhadauria Archana Singh , Rana Vikash
Published: February 2023

We have proposed an SVIQR epidemic model for COVID-19 with vac- cination in this research. Some fundamental characteristics such as positivity of the solution, boundedness and invariance of the model are analyzed. Expressions for disease-free equilibrium (DFE) and endemic equilibrium (EE) points with certain criteria for existence are derived. Rigorous analysis of the model reveals that as- sociated DFE is locally asymptotically stable whenever the effective reproduction number is less than one. Also, the EE point is stable whenever certain restric- tions are satisfied.  Sensitivity analysis is performed to identify key parameters that significantly affect the effective reproduction number. Analytical results are illustrated using parameter values and the results are analyzed using numerical simulation which suggests that the disease will eventually die out, particularly if the control measures are implemented above a specified level for a sustained period of time.

Biomaterials have occupied a prominent place in regenerative procedures to restore human health. Moreover, there is a greater need in understanding, analyzing and establishing their toxicity profile. These, when made into nano-sized constructions called nanostructured biomaterials, their regenerative potential is enhanced, which could influence their toxicity nature. This chapter intends to give comprehensive information on their nanotoxicology pathways at the cellular level, their entry pathways into the human body, and their potential consequences on human health. It clearly explains the cytocompatibility and biocompatibility of various nanostructured biomaterials for potential human health applications like drug delivery and tissue engineering. A detailed overview of various in vitro and in vivo evaluation methods of biocompatibility of nanomaterials are outlined in this chapter that researchers should address as they move forward in developing new systems for the field of regeneration.
Genetic Markers of Endothelial Dysfunction
Authors: Wybranska Iwona
Published: February 2023

The rate of endothelial dysfunction is influenced by genetic variation and thus inherited in families. Genetic disorders, such as familial hypercholesterolemia and homocystinuria, are at risk for premature atherosclerosis, and exhibit early endothelial dysfunction. The known spectrum of mutations in LDL receptor, APOB and PCSK9 gene represent the monogenic dominant hypercholesterolemia. An autosomal recessive form of hypercholesterolaemia in the caused by homozygous mutations in the LDL-R adaptor protein. The polygenic hypercholesterolaemia for patients with a clinical diagnosis of FH is based on the cumulative effect of LDL-C-raising alleles with a cumulative effect, in a complex interaction with the environment that leads to an increase in LDL-C, producing an FH-like phenotype and presenting this type of hypercholesterolaemia as a typical complex disease. The various causes of homocysteinaemia like genetic causes include mutations and enzyme deficiencies such as the most frequently mentioned 5, 10-methylenetetrahydrofolate reductase (MTHFR), but also methionine synthase (MS) and cystathionine β-synthase (CβS) but also by deficiencies of folate, vitamin B12 and, to a lesser extent, deficiencies of vitamin B6, which affects methionine metabolism, and leads also to endothelial disfunction in different mechanismms. Mutations in genes coding enzymes in homocysteine metabolism and also in nitric oxide (NO) synthesis, the main vasodilatator is also presented in this chapter. The crucial importance of microRNAs in endothelial physiology following EC-specific inactivation of the enzyme Dicer which is involved in altered expression of key regulators of endothelial function, including endothelial nitric oxide synthase (eNOS), vascular endothelial growth factor receptor 2 (VEGF), interleukin-8, Tie-1 and Tie-2. The new discoveries based on genome-wide screening (GWAS) complement the knowledge of the topic.

Brazil nut (Bertholletia excelsa Bonpl.) is vital for livelihoods in the Amazon region as a source of income and food, and since it is collected mainly from old-growth forests, it is also a cornerstone for forest conservation. This chapter presents socioeconomic and cultural characteristics of Brazil nut collectors, depicting their production systems and identifying individual perceptions about the effects of this activity on their livelihoods and on forest conservation. We interviewed 119 collectors, organized in associations, cooperatives, or autonomous informal organizations. Collectors live from agriculture, fishing, and forest extractivism, and reported the of use more than 30 forest products, highlighting their refined knowledge on forests. On the other hand, they have little access to formal education and information technology. The collection of Brazil nuts proved to positively impacts livelihoods’ capitals, being a key species for forest conservation and maintenance of Amazonian livelihoods. Forests are plentiful in Brazil nut trees and collectors are much more likely to remain in forests, incentivizing their conservation. Moreover, the organization into associations or cooperatives is especially positive to broaden sales options and achieve better market prices, breaking historical cycles where middlemen played a preponderant role in Brazil nut commercialization processes across the Amazon region.
Hyporesponsiveness to Erythropoietin-Stimulating Agents: Possible Solutions
Authors: Yasin Ahmed , Omran Nayer
Published: February 2023

Almost 80% of dialysis patients have anemia of different severity, with its pathogenesis of multifactorial nature. Relative insufficiency of erythropoietin leading to hyperproliferative erythropoiesis is considered the main underlying cause. Management of anemia has several therapeutic implications, including reasonable quality of life and avoidance of repeated blood transfusions, among others. Optimal maintenance of hemoglobin target levels is not easy, even with the implementation of different therapeutic options, including erythropoietin-stimulating agents (ESAs). Approximately 5–10% of patients are not responding adequately, despite incremental dosing of ESA therapy. That inadequate response has multiple heterogeneous causes, making anemia management rather difficult. Hyporesponsiveness to ESAs is a challenge requiring a proper approach.

Authors: Bahr Mahmoud Hussein , Elgamel Amira Fouad , Ahmed Ahmed Goda , Abdelkader Mohamed
Published: February 2023

Background: Postoperative cognitive dysfunction (POCD) following cesarean section (CS) is a growing and underestimated problem with unknown mechanisms. Studies suggest that general anesthesia (GA) plays a role in the development of early POCD. Objectives: This study aimed to assess the incidence of early POCD after elective and emergent CS under GA. Methods: We assessed the difference between the elective and emergent groups regarding the mini-mental state examination (MMSE), hemodynamic effects such as mean blood pressure (MBP), and heart rate (HR). Paired t-test was applied for intragroup comparison, and Student’s t-test (or Mann–Whitney U test, as appropriate) for intergroup comparison. Results: MMSE one hour after the operation was significantly lower than preoperative MMSE in the emergent group, and the MMSE tended to return to normal values faster in the elective than in the emergent group. Moreover, we found a significantly lower MBP and higher HR (at 15, 30, and 45 minutes) in both groups compared to preoperative values. Regarding intergroup comparison, MBP (at 30 minutes) significantly decreased in the elective group compared to the emergent group. Conclusions: There was a significantly lower POCD, especially at the first hour postoperatively, in the elective CS than in the emergent CS. Elective CS might have a positive effect on the women’s health as a mode of delivery.

The access mark to engineering studies is often used as an a priori success estimator. In our institution, we have observed that the correlation of the access mark with the grades obtained in project-based courses (R=0.52) is slightly lower than the one obtained with the average of the other non-project-based courses (R=0.58), and is especially low in capstone projects (R=0.31). Project-based and Challenge-based courses are one of the most acknowledged ways of promoting the learning of transversal skills, specifically innovation and entrepreneurship skills. In our institution, ICT engineering bachelor students perform a project-courses path, with three subjects of growing complexity in the 2nd, 3d and 4th year. While the first two are partially guided and with challenges proposed by the faculty members, the 3d one is a 12 ECTS capstone project with challenges proposed by industry or external institutions. In this study, we have analyzed the performance of the students along 10 academic years (2011-2012 to 2020-2021). Not only the correlation with the access mark in these courses is lower but the prediction interval is also different. While it is almost impossible that a student with a low access mark gets an outstanding average mark in the bachelor and vice-versa, there are students with a low access mark which have an outstanding performance in the capstone project and students with a very high access mark and with high results in analytical courses but with a poor performance in capstone projects. Therefore, a different kind of skills are promoted in these courses.
Peer mentorship: exploring the unmet needs of current mentees during Covid-19
Authors: Christensen Darcie , Villanueva Alarcón Idalis
Published: February 2023

Peer mentorship is a mutually beneficial relationship that allows two individuals who are at approximately the same experience level to interact with one another with the goal of providing personal, professional, or both types of support. It has been found that peer mentorship within academic settings have generally positive retention, persistence, and student experience outcomes for both mentors and mentees. While peer mentoring research and initiatives are growing, very few instances exist of determining student perceived needs regarding peer mentorship. As such, at a western institution in the United States, students were surveyed to self-report their perceived peer mentorship needs. This survey occurred during Fall 2021, just after the onset of the COVID-19 pandemic. Out of 223 participants, 79 students indicated that they currently had a peer mentor at the time the survey was administered. Students were given both a definition and examples of peer mentorship before indicating they had a peer mentor. Their mentors may have been formally assigned through an existing program at the college of engineering of interest or informally obtained through their own efforts. These 79 participants were asked what additional support they wish their peer mentor could provide. Through phenomenological analysis of open-ended responses, common avenues for additional support were determined. These findings allowed for development of recommendations for shaping the future implementation of more targeted and beneficial peer mentoring initiatives. The recommendations include providing flexibility in peer mentorship, training on resources and events, and a variety of peer mentoring opportunities early and consistently.
Debates on tech-related moral dilemas usign ethical theories to teach engineering ethics
Authors: Casany Guerrero María José , Alier Forment Marc
Published: February 2023

A significant number of universities where engineering is taught acknowledge the influence on society and the environment of the scientific and technological practice, as well as the ethical problems it presents, and the need to provide their students with courses covering this as a subject. The accelerated pace of innovation in these fields amplifies the issue. Computer Engineering schools are no exception. So, the IEEE/ACM Computer Science Curriculum 2013, identifies social issues and professional practice as key knowledge areas that computer undergraduate students must learn. Students should be knowledgeable about the interplay of ethical issues, technical problems, and aesthetic values that play an important part in the development of computing systems. The authors have taught for many years an optional course about the social, and environmental aspects of ICT as well as ethics. In this paper, the authors propose an approach to study ethics in Computer engineering schools. The approach consists in providing students with general ethic frameworks to reason about moral dilemmas as well as providing the basics of deontology. The lessons are complemented with case studies where technology is a key factor. Students are assigned roles to work on the cases and in the end, a discussion is done in the classroom. After the lessons, the authors have observed that students are able to understand and use the tools provided by the teachers to reason about moral dilemmas.

Covid19 outbreak has seen eLearning becoming a viable alternative to the traditional face-to-face teaching globally. Software engineering education has not been an exception to these changes. The use of multimedia enhanced eLearning communities is also on the increase in the teaching of software engineering. However, there is limited research on the acceptance of such tecnologies by African learners. Some of the multimedia being used to enhance these learning communities includes animated pedagogical agents (Pas) combining text, animation, audio, and video. Considering learner differences and aiming to achieve personalized learning, there is a need for institutions to understand how such tecnologies are being accepted by learners and the factors that influence the acceptance. This study focuses on the acceptance of pedagogical agent enhanced eLearning communities by Southern African learners in the teaching os Software Engineering. The aim of the study is to identify the factors that influence the acceptance of such communities. This will help eLearning designers to try and address the needs of learners in diferent contexts to achieve personalized learning. This study involved 137 software engineering students from South Africa and Zimbabwe who were being introduced to eLearning cimmunity enhanced with Pas. The unified theoryof acceptance and use of technology2 (UTAUT2) was used in this study. The study revealed that only performance expectancy, and hedonic motivation constructs ha dan effect on behavioral intention to use these eLearning communities enhanced with Pas.

Published: February 2023

The frequency reconfigurable reflectarray (RRA) reported in this paper provides a pencil beam at three frequencies captivating the need for satellite broadcast television at uplink and downlink frequencies in Ku band and X band. To achieve such frequency reconfiguration, a unit cell developed and simulated based on an infinite array approach is used in integration with four PIN diodes to produce a reflection phase variation of 525°, 415°, and 308° at 14.34 GHz for uplink operation, 12.2 GHz for downlink and 11.9 GHz for X-band performance respectively. In this proposed unit cell, the phase variation for uplink is achieved by varying the size of concentric loops, while in the case of downlink and X-band, reconfiguration controlled by pin diodes is achieved by varying the length of the delay line. With the periodicity of 0.49λ0 (10.5 mm), a 15 15 array with 225 elements is constructed using the designed unit cell on square planar geometry. The paper reports a maximum gain of 25.77 dBi, 25.13 dBi, and 22.7 dBi and 40.22%, 26.46%, and 25.36% of aperture efficiency at 14.34 GHz, 12.2 GHz, and 11.9 GHz respectively. A -3dB gain bandwidth of 8.37%, 4.92%, and 12.18% is achieved at the three operating frequencies by simulation. Hence this reconfigurable reflectarray serves as an emulous alternative to parabolic reflectors and phased array antennas in deep space communication and direct broadcast satellite applications satisfying the high gain pencil beam requirements.
