The study was carried out from August to September 2016 in the Western Highlands of Cameroon. The main objective was to contribute to a better understanding of biodiversity of honeybees for their preservation and genetic improvement. To attain this, samples of 420 workers bees belonging to Apis mellifera subspecies were obtained from 14 localities in the study zone. Body measurements in mm gave the following values: honey bee length (10.98 ± 0.06), abdomen length (6.71 ± 0.03), width of the yellow band on the second (2nd) abdominal tergite (1.48 ± 0.01), width of fourth (4th) abdominal tergite (1.32 ± 0.01), length of cover hair on the fifth (5th) abdominal tergite (0.29 ± 0.00), antenna length (4.27 ± 0.02), proboscis length (4.39 ± 0.11), length of nervure A (0.60 ± 0.00), length of nervure B (0.25 ± 0.00), discoidal shift (-0.13 ± 0.01), anterior right wing length (9.31 ± 0.03), anterior right wing width (3.14 ± 0.01), posterior right wing length (6.38 ± 0.03) and posterior right wing width (1.69 ± 0.01). A correlation coefficient significantly (p<0.01) higher (0.72) was obtained between the length of posterior right wing and the length of the anterior right wing. The cubital index is 2.36 ± 0.04. Populations of honeybees studied consist of three genetic types; genetic types 2 and 3 are closer together. The observed biodiversity suggests that honeybees constitute a natural resource with genetic variability needed for preservation and genetic improvement.

Growth traits characterization of Nigeria homing pigeons was done using one hundred and thirty eight (138) birds from three locations (LCT) of different agro-ecological zones in Nigeria [Kebbi (KEB):North West; Ilorin (ILR): North Central and Osogbo (OSG): South West]. Parameters measured were body weight (BW) in gram and morphometric body parameters in cm viz. Head length (HL), beak length (BL), neck length (NL), body length (BL), body girth (BG), wing length (WL), body height (BH), thigh length (TL), drumstick length (DL) and keel length (KL). The results showed that, significant (p<0.05) differences existed between body weight and body parameters measured except BL. ILR pigeons had significantly (p<0.05) higher BW (263.51g) compared to OSG (204.15), but similar (p>0.05) to KEB (249.76g); the morphometric body parameters measured showed that HL, BG and WL values were significantly (p<0.05) higher in ILR; OSG had significantly (p<0.05)  higher values for  KL, while KEB pigeons had  significantly (p<0.05) higher values for  BL, NL, BH, TL, DL, and SL. Positive and significant correlations (p<0.01, 0.05) exists between locations, NL, SL and BH; BW was negatively correlated with locations with a significant (0.01) value of -0.58. PCA shows the clustering of growth traits from 18.94 to 25.14% under PC1 and 2, canonical discriminant functions gouped KEB and OSG with 56.60%; ILR and KEB with 43.60% while hierarchical clustering shows that KEB homing piegons are distinct from those of ILR and OSG. This results shows that  locations have significant effects on growth traits in Nigeria homing pigeons.

A total of 81 samples captured between November 2017 to September 2019 were morphometrically analyzed as part of this study. In this latter we tried to compare between the population of the dam (artificial environment) and the population of the river (natural environment) in two watersheds for two different species of Luciobarbus in western Algeria. Sites A (natural) and B (artificial) are located at almost the same altitude (285-571 m) whereas sites C (artificial) and D (natural) are located in two different altitudes (285-571 m) and (1078-1821 m) respectively. The analysis of variance (ANOVA) was carried out to test the significance of the variations of each morphometric character between the 4 populations (A, B, C and D). The values of all the external morphometric parameters were the highest in the population of the Boughrara dam followed by El-hammam river and Bouhanifia dam while the population of Chouly river showed the lowest morphometric measurements. The mean of total length (TL) and weight (Weight), for example, of the Boughrara dam were the largest of the four populations (33.03 ± 2.02 cm and 474.46 ± 116.76 g respectively) while those of the river Chouly were the smallest (15.44 ± 1.23 cm and 55.55 ± 13.01 respectively). The sex ratio analysis was performed by studying the overall sex ratio. Females were more abundant than males (1: 1.7). The graphical representation of Quantitative Variables by PCA showed that the morphometric variables are all positively correlated with each other by quite different rates. The Shannon and Weaver index was calculated from the different characters in the four regions studied: A, B, C and D. The region of site B (Bouhanifia dam) had the highest average diversity index with 0.92, followed by the region of site A (El-hammam river) (0.88). The lowest mean value was found in site C (Chouly river) (0.29).

Studies suggest that the welfare of captive chimpanzees can be improved by providing different kinds of enrichments. Sensory enrichment has gotten more attention lately, by e.g. using sounds and images. The purpose of this study was to examine the differences in behavior, using asleep meditationpodcast asenrichment.An ethogram wasmade to categorizethe different behaviors. The difference between the medians of each behaviorwas then tested with a Mann-Whitney U test. Furthermore, the personalities of the chimpanzees were analyzed, byfirst plotting X-Y graphs of the median, kurtosis, skewness, and IQR.Afterward, χ2 tests were performed on the slopes, todetermineif there were any significant differences in the chimpanzee’s personalities.Additionally, behavioral diversity was calculated and compared with χ2 tests. Based on these tests, it was not possible to conclude whether the sleep meditation causedachange in behavior in the enrichmenttestperiod. It is however possible to conclude that the study showed a significant difference in the personalities, between some of thechimpanzees.

Polar bears (Ursus maritimus) are vulnerable to environmental changes, which often leads to the development of stereotypical behaviour in captivity.Multiple studies hadshownthat the usage of enrichment could reduce stereotypicalbehaviour in captive animals thereby, improving their welfare. When choosing enrichments,it is necessary to examine the individual personalities, since differences in behavioural reaction norms of the medianscould lead to different preferences among animals regarding the types of enrichment used.This study investigated the behaviour of three polar bears (one adult female and her two cubs)at Aalborg Zoo and whether different types of enrichment would have an impact on their behaviour and reduce stereotypes. Furthermore, this study also investigatedwhether the three polar bears differed in their behavioural reaction norms, behavioural instability, and behavioural diversity. No differences were found in behavioural reaction norms between the enrichment days and control days, except for, the skewness and kurtosis. The mother bear was observed to have more stereotypical behaviour than her cubs, which correlated well with her low behavioural diversity index. A significant difference in behavioural reaction norms was found between the mother and her cubs although, there was no difference between the cubs’ reaction norms. So, no significant differences in behavioural reaction normsand behavioural instability were found between thetwo cubs.

Published: February 2022

The dairy cattle husbandry systems in semi arid climate require adapting as a response to climate change. In this study, we focus on semi arid climate of Mediterranean region to assess the effect of heat stress on productive and physiological parameters of Holstein cows. The temperature-humidity index (THI), calculated as a combination of ambient temperature and relative humidity, was used to characterize heat stress. The averages of index (THI) are 71.7, 83.6 and 72.6 respectively for spring; summer and autumn. when the THI increased from average value 12 unit between spring and summer, the cows decreased their daily milk production (DMP) and dry matter intake (DMI) by 17.6 % kg/day and 22 % respectevelly. THI value was negatively correlated to DMP with regression equation DMP (kg /day) = -0,36THI+40.8 (r2 =0.72).  in semi arid condition a daily increase was observed for RT, RR an HR respectively when the THI value increased from 71.7 to 83.6 (RT 38.6˚C to 39.1˚C; RR 49.3 inspiration/min to 71.6 inspiration/min and HR 52.6beat/min to 72.7 beat/min for spring and summer respectively) with positive correlation between THI and RR, HR and RT. significant seasonal variation was detected for all physiological parameters for spring, summer and autumn period. Summer heat stress affected the physiological functions of lactating Holstein cows reared under semi arid Mediterranean climatic conditions. The Holstein breed cows are sensitive to heat stress in semi arid conditions. In the context of cow breeding practiced in conditions of semi-arid heat stress, it is necessary to find alternatives in terms of management or genetic improvement, in order to alleviate the impact of climatic stress on performance and physiological parameters.

Published: February 2022

The lipochromic mosaic canary is a cage bird breed present with different coat colors, red, and yellow, this breed presents a significant sexual dichromatism. Dichromatism in lipochromic mosaic canaries is explained by differential carotenoid degradation in the integument, rather than sex-specific variation in physiological functions such as pigment uptake or transport. Males have an intense color compared to females and especially at the shoulders and head. We studied sexual size dimorphism (SSD) because this study aimed to investigate whether gender has an impact on thirteen body measurements which are (Head Length, Head Width, Distance Between the Eyes, Beak Length, Beak Width, Chest Circumference, Body Length, Body Width, Wing Length, Sternum Length, Upper Tarsus Length, Lower Tarsus Length, and Tail Length) in 40 native lipochromic mosaic canaries (19 males and 21 females) raised in the Wilaya of Tlemcen Northwest of Algeria. The results showed that there were differences between genders for three characters that are CC (Chest Circumference), BL (Body Length), and WL (Wing Length).  Males had more developed measurable traits than females.

Indigenous livestock resources are strategic in the socio-economic of rural agricultural systems to ensure food and nutritional security in resource-poor countries. In Cameroon, small ruminant farming significantly contributes to food security and income generation. Given its great ecological variety, Cameroon hosts a large genetic diversity of sheep, but the knowledge on these is scanty. In order to contribute to a better understanding of the genetic diversity of Cameroon's Ovine genetic resources for their better use and conservation, an analysis of the Djallonke sheep genetic diversity based on the D loop of the ovine mitochondrial DNA (mtDNA) was performed on the highlands of West Cameroon Djallonke breed. To achieve this, analyses of 16 sequences of a 989bp fragment of the mtDNA D-loop region from the population were conducted in conjunction with previously published sequences from African, European, Japanese and Chinese ovine genotypes. Fourteen haplotypes were observed with a high mean haplotype diversity of 1.0000±0.027, nucleotide diversity (π) of order of 0.11082±0.062. The average nucleotide difference between sequences taken two by two was 62.945. Population specific FST indices showed a negative and significant result for the whole data set. The phylogenetic tree indicates that the mitochondrial lineages of these sheep breeds originated from a common source, the Haplogroup B. This confirms the hypothesis that the domestication of African sheep was carried out in successive waves from Asia. The results of this study contribute to the knowledge of Cameroon sheep breeds and the plan conservation programs on Djallonke sheep.

Published: February 2022

The present work involved updating information on the Muturu cattle breed in Benin, in order to design a sustainable breeding management scheme for its conservation. A total of 108 farmers were interviewed and 216 adult cattle physically looking like Muturu cattle as described previously were sampled in 6 departments of Southern Benin spread over 4 agro-ecological zones. Forty-one (41) qualitative traits were assessed and 10 to 11 morphometric measurements were carried out using the Animal Genetic Resources Characterisation, Inventory and Management Tool. The proportions and means obtained were analysed respectively by analysis of variance and two-tailed Z tests contained in the Agricola package of the R analysis software. The results showed that the lowest morphometric measurements were obtained from the animals of the department of Ouémé. These values were similar to those reported earlier in Muturu cattle. However, the highest values were obtained on animals from Mono and Couffo departments and were close to the values reported on taurine zebu cattle previously. Herd clustering results revealed the existence of subgroups in the populations of Muturu cattle of the Atlantic and Mono departments. Subject to confirmation by molecular testing, this study revealed that currently, Muturu cattle are found in the departments of Ouémé, Plateau and Atlantic in Benin where populations from Ouémé department are physically the closest to breed as described previously. The department of Zou has almost no Muturu cattle, and the departments of Couffo and Mono are dominated by Zebu x Muturu crossbreds. It is important therefore to design a conservation programme for the breed where it’s still found, as its existence would probably be linked to the preferences of the cattle keepers and the local communities and to its capacity to overcome the challenges of these ecosystems.
Crypto Minning : Indonesia Carbon Tax Challenges and Safeguarding International Commitment on Human Security
Authors: Putranti Ika Riswanti
Published: February 2022

The need for financial transactions in the virtual world that continues to grow demands an increase in the speed, quality, and quantity of various innovations and discoveries in the field of financial technology known as cryptocurrency. This discovery encourages various developments of the virtual world economy which is increasingly diverse and growing according to the needs and interests of existing economic actors. Cryptocurrencies are currently only considered as digital assets that can be traded so they are not recognized as a means of payment. However, cryptocurrency trading in Indonesia is a fast-growing field, so its economic value continues to rise rapidly. This encourages the emergence of crypto mining businesses that tend to use large amounts of electricity. The issue of carbon footprint in cryto mining has in several ways been the cause of the prohibition of this activity. In Indonesia, this activity is still not banned, in 2022 a carbon tax will be applied where every kilogram of carbon equivalent emissions that exceed a certain cap will be subjected to Rp-30 (0.21 cent dollar) tax. So the paper tries to analyze the extent to which this carbon tax will affect crypto mining in Indonesia and how the mitigation of crypto mining's carbon footprint can be managed through proper regulation without disturbing the crypto economic sector that is blooming in Indonesia.

Published: February 2022

This study was carried out to determine the microorganism population affecting silage quality of sweet sorghum and mung bean cultivated with different sowing patterns as mixture or sole crop. Twin row (20×55 cm row spacing), narrow row (55 cm row spacing) and conventional row (75 cm row spacing) were used as mixture sowing patterns. The mixtures were formed based on the plant densities and alternative row numbers of sweet sorghum and mung bean. Sowing was made on alternation rows of 1 row mung bean plus 1 row sweet sorghum (R1:1) and 1 row mung bean plus 2 rows sweet sorghum (R1:2). In pure and mixed cultivations, the plant density of sorghum was 14 plants m-2 while the plant densities of mung bean were 14, 21 and 28 plants m-2. The experiment was planned as two-factors (sowing patterns and mixtures) and was arranged in randomized blocks according to the split plot design with 3 replications. Pure and mixed plants were harvested when the sweet sorghum plant reached the dough stage. Lactic acid bacteria, enterobacteria and yeast and mold populations in the plant epiphytic flora were investigated under experimental factors. There were significant effects of the main factors and their interactions on the plant epiphytic microorganisms. According to the results obtained from the current study, mixed cultivation of sweet sorghum and mung bean in conventional row pattern improved the desired lactic acid bacteria population for silage quality, while reducing the undesirable enterobacteria and yeast and mold population for silage quality. It was determined that the (R1:2) MB14+SS14 mixed cultivation system was the most suitable mixture in conventional row pattern in terms of high lactic acid bacteria population.

Published: February 2022

On the market there are several LED lamps that were not designed to produce lettuce, however, they can be purchased at a low cost. In Mexico there is a lack of research on its use in small-scale vertical farms and hydroponic established in urban agriculture. The objective of this work was to measure the response of three commercial lamps with LED lights on the growth and morphogenesis of sangria lettuce grown in a low-cost home vertical farm. The sangria lettuce was subjected to three light intensities with different spectra and photoperiod after 30 days of growth the plant height, leaf length, leaf width, number of leaves and fresh weight were measured, and a one-way analysis of variance (ANOVA) and Duncan's multiple comparison method was used through an algorithm designed in Python. According to the results, the highest fresh weight is made for a light intensity of 5700 lux. In the 2100 lux treatment, the highest height of the plant is performed and it was the treatment with the highest energy consumption. The production of lettuce at home is technically feasible, however, in addition to the light intensity, it is necessary to evaluate the quality (wavelengths) from the agronomic point of view.

The emergence of the novel coronavirus, SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) has resulted in a major global pandemic posing various challenges to the worldwide health care systems. Clinical course of the infection, known as coronavirus disease of 2019 (COVID-19, ranges from mild subclinical disease to a life-threatening systemic illness. Common symptoms include a flu-like illness with fever and inflammation, and in severe cases pneumonia and systemic inflammation that results in morbidity and mortality. One of the complications of COVID-19 is its disruption of normal hemostasis resulting coagulopathy and thromboembolism. In this following review, we discuss present knowledge; summarize existing published information on the underlying mechanisms of action for COVID-19-associated coagulopathy; and propose algorithms for screening, management, and prevention of COVID-19 patients.

This paper explores the experiences of sociocultural adjustment of four multilingual international students who speak English as an additional language (EAL) at a Canadian university. International students have been associated with negative images of failure and disruption to higher education on the basis of the hierarchy of cultures that privileges local and western knowledge. Multilingual EAL international students in particular have been broadly characterised as deficient speakers of English considering their non-native proficiency. From this point of view, multilingual international students tend to experience a kind of double deficit as they are compared to both local and native-speaker students. By employing interviews and photographs, this paper seeks to understand and represent the experiences of sociocultural adjustment of the four students and provides an emic, balanced account of each student’s journey which also takes into account the ways in which the students exercised agency. Findings demonstrate the complexity of the international student experience and the importance of meaningful social interaction for multilingual international students to feel included in their communities. Photographs depict experiences from the students’ perspectives which the students considered representative of positive sociocultural adjustment, but also of challenges in the same domain. This paper concludes with insights related to improving the sociocultural adjustment experiences of multilingual international students.

Published: February 2022

Current research has shown varied results when comparing the effects of energy drink on anaerobic exercise measures. Athletes in Ghana have been using energy drink but hardly has any research been conducted on the effect this pre-exercise consumption has on their physical performance. The purpose of this study was to find out the effects of short-term consumption of energy drink on some blood pressure, heart rate, agility, lower body strength and upper body strength of athletes of the University of Cape Coast. To ascertain this, participants were taken through performance tests in a pre-test and a post-test. The intervention in this study was the consumption of 250ml of energy drink. Forty-four athletes (Age:22.32 ± 2.81 years, height: 167.2 ± 9.83 cm, weight: 61.12± 8.01 kg). Paired sample t test results showed no significant effect of energy drink consumption on systolic blood pressure (t = -0.78, p= 0.437), diastolic blood pressure (t = -0.91, p = 0.366), heart. rate (t = -030, p = 0.759) and lower body strength (t = 0.11, p =0.916). However, there were significant changes in agility (t =5.42, p = 0.001) and upper body strength (t = -2.79, p = 0.008). In view of this, athletes, trainers, and coaches could consider recommending the use of energy drink as a pre-exercise supplement, especially in events involving agility and upper body strength.

Bu araştırmanın amacı, beliren yetişkinlerin mükemmeliyetçilik ve psikolojik kırılganlık düzeylerinin çeşitli değişkenler (cinsiyet, yaş, mutlu çocukluk yaşantısı ve algılanan anne baba tutumu) açısından incelenmesidir. Bu nicel araştırmada, yordayıcı ilişkisel tarama modeli kullanılmıştır. Araştırmanın katılımcılarını tesadüfi örnekleme ile seçilmiş 320 (248 kadın ve 72 erkek) beliren yetişkin oluşturmaktadır. Araştırmanın verilerinin toplanması amacıyla Kişisel Bilgi Formu, Frost Çok Boyutlu Mükemmeliyetçilik Ölçeği ve Psikolojik Kırılganlık Ölçeği kullanılmıştır. Ölçeklerden elde edilen verilerin analizi için Pearson momentler çarpımı korelasyon analizi, basit doğrusal regresyon analizi, bağımsız örneklemler t Testi, tek yönlü varyans analizi (ANOVA) ve LCD post hoc testi kullanılmıştır. Verilerin analizi sonucunda elde edilen bulgulara göre; beliren yetişkinlerin mükemmeliyetçilik düzeyleri ve psikolojik kırılganlık düzeyleri arasında anlamlı pozitif bir ilişki vardır. Ancak katılımcıların, psikolojik kırılganlık ve mükemmeliyetçilik puanları cinsiyete göre istatistiksel olarak anlamlı bir şekilde farklılaşmamaktadır. Mutlu çocukluk yaşantısına sahip olmayan beliren yetişkinler, sahip olanlara göre psikolojik açıdan daha kırılgan ve daha mükemmeliyetçidir. Demokratik tutuma sahip hem annelerin hem de babaların çocukları daha az kırılgan ve daha az mükemmeliyetçi bulunmuştur. Araştırmanın bulguları ilgili araştırmalar ışığında tartışılmıştır.

Period Variations of Cepheids and Stellar Evolution
Authors: Berdnikov L.N. , Samus N.N.
Published: February 2022

Classical Cepheids are pulsating supergiants in the main instability strip. In the course of evolution, they move across theinstability strip, and their periods vary. Studying their period variations for a time span of several decades, it is possible todetermine the rate of secular period increase or decrease, identify the number of instability strip crossing, and thus improvethe period–luminosity relation. Special tests are used to determine whether the observed period variation is real or causedby random errors.
On some recent advances in celestial mechanics
Authors: Kondratyev B. , Emelyanov N.
Published: February 2022

The article is based on the plenary report at the VAK 2021. It describes the development of ideas and reviews somerecent achievements in modern celestial mechanics. We proceed from the fact that the classical deﬁnition of this sciencegiven in textbooks and encyclopedias does not fully reﬂect the content of modern celestial mechanics. A broader and morecapacious term is “dynamic astronomy”. This science is complex and includes not only classical but also relativistic celestialmechanics, as well as the theory of equilibrium ﬁgures and computer simulations; besides, we should not forget aboutqualitative methods, the peak of which is the creation of KAM theory. Here we trace the development of a chain of ideasfrom Keplerian orbits to osculating Lagrange ellipses, which leads eventually to Gaussian rings and two models (R-disk andR-toroid) based on precessing Gaussian rings. The review also includes a presentation of results obtained in recent years byresearch groups in the Russian Federation.

We have made the high-resolution measurements of pulsar scattering disks with the RadioAstron. For three pulsars,B1641−45, B0833−45, and B0834+06, we measured the angular size with various directions of baseline projections and wewere able to estimate the anisotropy of their scattering images. An aspect ratio of all elliptical images no more than 2:1 isconsistent with the data.

Published: February 2022

We present the results of the numerical simulations of the collapse of magnetic rotating protostellar clouds with mass 10M ⊙ . The hierarchical structure of the cloud formed at the isothermal stage of the collapse is investigated for various initialratios of the magnetic energy of the cloud to the modulus of its gravitational energy, ε m . It is shown that the size of thequasi-magnetostatic primary disk and the region of eﬃcient magnetic braking increase with ε m . In the case ε m ≥ 0.6,practically the entire cloud evolves into the state of quasi-magnetostatic equilibrium. A ‘dead’ zone forms inside the ﬁrsthydrostatic core and in the area of the outﬂow formation, where Ohmic dissipation and ambipolar diﬀusion become essential.
