Published: December 2020

Kebutuhan material baja dengan berbagai kombinasi sifat mekanik menjadi isu yang sangat penting dalam perkembangan teknologi pada berbagai bidang. Kombinasi sifat mekanik tersebut dapat diwujudkan antara lain melalui mekanisme modifikasi fasa atau struktur mikro dalam suatu material. Berbagai teknik untuk memodifikasi fasa telah banyak dikembangkan, salah satu diantaranya melalui proses perlakuan panas. Penelitian ini membahas pengaruh variasi penggunaan media pendingin terhadap struktur mikro dan nilai kekerasan baja Fe-Ni. Sampel baja yang digunakan merupakan baja hasil proses tempa panas dengan pembebanan 100 ton pada suhu 1000°C. Sampel baja hasil tempa dipanaskan kembali pada suhu diantara Ac1 dan Ac3 yaitu 780 °C selama 1 jam. Kemudian masing-masing sampel dilanjutkan dengan proses pendinginan menggunakan beberapa media pendingin diantaranya udara, oli dan air. Berdasarkan analisis yang telah dilakukan, sampel baja as-cast dan baja pendinginan udara memiliki struktur mikro berupa ferit-perlit. Fasa ganda ferit-martensit terbentuk pada sampel dengan pendingin oli dan air dengan morfologi dan fraksi area yang berbeda. Bentuk fasa martensit yang dihasilkan media pendingin air cenderung berbentuk lath halus, sedangkan media pendingin oli menghasilkan fasa martensit berbentuk blok. Selanjutnya, fraksi area fasa ferit-martensit yang terbentuk juga dipengaruhi oleh kecepatan pendinginan. Fraksi area martensit memiliki kecenderungan meningkat seiring dengan peningkatan kecepatan pendinginan. Kondisi tersebut berpengaruh terhadap nilai kekerasan; sampel baja hasil pendinginan dengan media air memiliki nilai kekerasan tertinggi yaitu 520 HV.

Application of Probit Analysis in the Decision of Youths to Participate in Vegetable Production
Authors: Etim Nsikak-Abasi , Thompson Dorothy 
Published: December 2020

Youths are successor farming generation and therefore the future of food security. At present, they constitute about 60% of Nigeria’s population and have over the years contributed significantly to national development. Unfortunately, the present environment makes it difficult to explore their full potentials in production through participation in agriculture. The ageing smallholder farmers are less likely to increase capacity needed to sustainably expand agricultural production. There is therefore a pressing need to engage the youth in ways that they can see a promising future in agriculture as well as influence them to build capacity through effective involvement in agricultural production. Several factors however, have continued to hinder capacity building and effective participation of youths in vegetable farming. An empirical study was conducted to estimate the factors affecting the willingness of youth to participate in small scale waterleaf production. The representative waterleaf producers were selected using the multi stage sampling procedures.With the aid of questionnaire, primary data were obtained from 100 farmers. Univariate probit regression model was used to analyze the data. Results of analysis indicated that the most critical factors affecting the participation of youths in waterleaf production were age, educational qualification, size of household members, and farm income. Results indicated that youths who have acquired some form of education were more willing to be involved in waterleaf production. Findings further indicated that youth in families with higher income from farming activities were more willing to participate in waterleaf production.

Artikel ini mengulas Pemenuhan Elemen Necessary Conditions Kecamatan dalam penyelenggaraan pemerintahan umum baik secara nasional dan spesifik diperdalam dengan fakta empiris di Kabupaten Pandeglang, hal itu sebagai konsekuansi dari pelaksanaan Undang – Undang Nomor 23 Tahun 2014. Penelitian dilakukan dengan menggunakan pendekatan kualitatif. Hasil penelitian diketahui, penyelenggaraan pemerintahan umum Kecamatan baik fakta secara nasional serta pendalaman fakta empiris di Kabupaten Pandeglang menunjukan belum cukup tertopang oleh elemen necessary condition diantaranya kepastian atas kewenangan legalnya serta anggaran yang menyertainya. Oleh sebab itu dipandang perlu ada kemauan politik baik itu dari Presiden untuk segera mengundangkan Peraturan – Pemerintah sebagai landasan teknis bagi pemerintah daerah selaku kepala wilayah maupun dari Kepala Daerah Kabupaten/Kota untuk melakukan terobosan agar supaya di masa peralihan implementasi Undang – Undang Nomor 23 Tahun 2014 kewenangan – kewenangan pada bidang kesatuan bangsa, keamanan dan keteriban umum dapat dilimpahkan pada Kecamatan serta Elemen Necessary Conditions lain yang menyertainya diperkuat.

This article discusses the fulfillment of the elements of the sub-district's necessary conditions in the administration of general government both nationally and specifically and deepened by empirical facts in Pandeglang Regency, this is a consequence of the implementation of Law Number 23 of 2014. The research approach used is qualitative. The results showed that in the administration of district general government both the facts nationally and the deepening of empirical facts in Pandeglang district were not sufficiently supported by elements of necessary conditions, including certainty of legal authority and budget. Therefore, there needs to be political will, both from the president, to immediately ratify the Government Regulation as a technical basis for the regional government (Territory) as well as from the Head of Regency / City to make breakthroughs so that in the transitional period the implementation of Law Number 23 Year 2014 powers in the areas of national unity, security and public order can be transferred to the District and the accompanying elements of necessary conditions are strengthened.
Secondary attack rates of COVID-19 in diverse contact settings, a meta-analysis
Authors: Tian Ting , Huo Xiang 
Published: December 2020

Introduction: The secondary attack rate (SAR) measures the transmissibility of an infectious agent. The reported SAR of COVID-19 varied in a broad range, and between different contact settings.
Methodology: We conducted a meta-analysis on the SAR of COVID-19 with adherence to the PRISMA guideline. We searched published literatures and preprints in international databases of PubMed and medRxiv, and in five major Chinese databases as of 20 April 2020, using the following search terms: ("COVID-19" and "secondary attack rate") or (“COVID-19” and “close contact”). The random effect model was chosen for pooled analyses, using R (version 3.6.3).
Results: A total of 1,136 references were retrieved and 18 of them remained after screening. The pooled SAR of COVID-19 was 0.07 (95%: 0.03-0.12) in general. It differed significantly between contact settings, peaking in households (0.20, 95%: 0.15-0.28), followed by in social gatherings (0.06, 95%: 0.03-0.10). The point estimates of the pooled SARs in health facilities, transports, and work/study settings were all as low as 0.01. Among all the secondary cases, the proportion of asymptomatic infections was estimated to be 0.17 (95% CI: 0.09 – 0.34). The proportion was higher in households (0.26, 95% CI: 0.12-0.56), than in other contact settings.
Conclusions: The transmission risk of SARS-CoV-2 is much higher in households than in other scenarios. Identification of asymptomatic secondary infections should be enhanced in households.
The Effect of Chronic Treatment with Lacosamide and Topiramate on Cognitive Functions and Impaired Emotional Responses in a Pilocarpine-induced Post-status&nbsp;Epilepticus Rat Model
Authors: Shishmanova-Doseva Michaela , Tchekalarova Jana , Nenchovska Zlatina , Ivanova Natasha , Georgieva Katerina , Peychev Lyudmil 
Published: December 2020

Introduction: Epilepsy and antiepileptic drugs can affect negatively the cognitive abilities of patients.
Aim: The present study aimed to evaluate the effect of topiramate (TPM) and lacosamide (LCM) on the emotional and cognitive re-sponses in naive animals and in animals with pilocarpine-induced status epilepticus.&nbsp;
Materials and methods: Male Wistar rats were randomly divided into 6 groups and status epilepticus was evoked in half of them by a single i.p. administration of pilocarpine (Pilo) (320 mg/kg): Pilo-veh, Pilo-TPM (80 mg/kg) and Pilo-LCM (30 mg/kg). Matched naive rats were treated with the same doses as follows: C-veh, C-TPM, and C-LCM. In a step-down passive avoidance test, the learning session was held for one day, the early retention test was conducted on day 2, and the long-term memory test - on day 7. Motor activity and anxiety were evaluated in an open field test.&nbsp;
Results: The Pilo-TPM and Pilo-LCM groups increased the time spent on the platform compared to Pilo-veh animals while the C-LCM animals decreased the time compared to C-veh animals during short- and long-term memory retention tests. TPM and LCM exerted an anxiolytic effect in naive rats. The two antiepileptic drugs were unable to alleviate the hyperactivity, but they alleviated the impulsivity associated with decreased anxiety level in epileptic rats.
Conclusions: Our findings suggest that LCM and TPM have a beneficial effect on cognition both in naive and epileptic rats. While the two antiepileptic drugs can produce an anxiolytic effect in naive rats, they alleviate the impulsivity after pilocarpine treatment.

Aim: The aim of this study is to analyze the mesophilous forests of Albania including Fagus sylvatica and submontane Corylus avellana forests. Mesophilous Albanian forests are poorly known and were not included in the recent syntaxonomic revisions at the European scale. Study area: Albania. Methods: We used a dataset of 284 published and unpublished relevés. They were classified using the Ward’s minimum variance. NMDS ordination was conducted, with over-laying of climatic and geological variables, to analyze the ecological gradients along which these forests develop and segregate. Random Forest was used to define the potential distribution of the identified forest groups in Albania. Results: The study identified seven groups of forests in Albania: Corylus avellana forests, Ostrya carpinifolia-Fagus sylvatica forests, lower montane mesophytic Fagus sylvatica forests, middle montane mesophytic Fagus sylvatica forests, middle montane basiphytic Fagus sylvatica forests, upper montane basiphytic Fagus sylvatica forests, upper montane acidophytic Fagus sylvatica forests. These can be grouped into four main types: Corylus avellana and Ostrya carpinifolia-Fagus sylvatica forests, thermo-basiphytic Fagus sylvatica forest, meso-basiphytic Fagus sylvatica forest and acidophytic Fagus sylvatica forests. This scheme corresponds to the ecological classification recently proposed in a European revision for Fagus sylvatica forests Conclusion: Our study supports an ecological classification of mesophilous forests of Albania at the level of suballiance. Analysis is still preliminary at the level of association, but it shows a high diversity of forest types.

Published: December 2020

Aims: To complete the syntaxonomic scheme for tall-forb vegetation of the montane and alpine belts in the Pamir-Alai and western Tian Shan Mountains in Tajikistan and Kyrgyzstan with some remarks on its environmental predictors. Study area: Middle Asia: Tajikistan and Kyrgyzstan. Methods: A total of 244 relevés were sampled in 2013–2019 using the seven-degree cover-abundance scale of the Braun-Blanquet approach. These were classified with a modified TWINSPAN algorithm with pseudospecies cut-levels 0%, 5% and 25%, and total inertia as a measure of cluster heterogeneity. Diagnostic species were identified using the phi coefficient as a fidelity measure. NMDS was used to explore the relationships between the distinguished groups. Results: Our classification revealed 19 clusters of tall-forb vegetation in Middle Asia. Among others we found forb communities typical for Tian Shan, western Pamir-Alai, forb-scree vegetation of Pamir-Alai, dry tall-forbs and typical forbs of the alpine belt. A total of eight new tall-forb associations and five communities were distinguished. The forb vegetation of Middle Asia has been assigned to the class Prangetea ulopterae Klein. The main factors differentiating the species composition of the researched vegetation are elevation, mean annual temperature, sum of annual precipitation and inclination of the slope. Conclusions: The paper presents the first insight into the comprehensive classification of the alpine forb vegetation in Middle Asia and fosters progress in explaining the relationship of boreo-temperate and Mediterranean-like (Irano-Turanian) vegetation in western Asian and central Asian subregions of the Irano-Turanian phytogeographical region.

Authors: Jiménez-Alfaro Borja , Font Xavier 
Published: December 2020

SIVIM Alpine (GIVD ID: EU-00-034) is a thematic database focused on vegetation plots from alpine grasslands of the Iberian Peninsula. The main aim of the database is to centralize historical and new vegetation plots of grassland-like communities above the treeline from Spanish mountains, the Pyrenees (including France and Andorra) and Serra da Estrela (Portugal). The database was registered in GIVD in December 2020, and it is currently available in EVA under semi-restricted regime. SIVIM Alpine includes both digitized relevés from the literature and unpublished data. Most of digitized relevés overlap with SIVIM (GIVD ID EU-00-004) but the header data and the geographical coordinates of SIVIM Alpine have been improved when possible. The database is routinely updated with new surveys conducted with GPS and detailed ecological data. Nowadays, SIVIM Alpine contains 6,420 vegetation plots corresponding to all phytosociological alliances described in the Iberian Peninsula for high-mountain grassland vegetation, 85% of them also classified at the association level. Plot size is available for 80% of the relevés. Plant taxonomy keeps the names provided by the original authors of the relevés, with an additional correspondence to Euro+Med and The Plant List, when possible. The database is continuously updated by revisiting the original sources. Different versions of the database have been used to vegetation analysis at national at continental scales.
