General “Maize” as One of the Failed Managerial Experiments of N. S. Khrushchev
Authors: Lushin A. I.
Published: December 2022

Goals. Based on the analysis of materials from the Soviet press, scientific publications and a number of other sources, to show the hyperactive activity of the First Secretary of the CPSU Central Committee N.S. Khrushchev on the widespread introduction of corn crops in the country, to reveal how ill-conceived and not calculated from a scientific point of view, managerial decisions in an authoritarian political system can lead to serious negative socio-economic and political consequences.Materials and methods. N.S. Khrushchev’s speeches at party congresses, plenums, activists and other forums, party and government resolutions concerning the party leadership of the agrarian sphere of the country were chosen as the basic materials of the work. The main method of working with sources and scientific literature is the historical approach, which is traditional for this kind of research, which allowed us to consider the dynamics of the origins of the “corn epic”, its development and historical finale. In addition, a problem-chronological approach was used, which contributed to the study of specific aspects of the activities of the First Secretary of the CPSU Central Committee, which allowed to trace the causes of the origin and development of the campaign initiated by him, but also to draw historical lessons from its deplorable results.Results. One of the negative results of the policy of “universal maize” imposed by N. Khrushchev in the life of the agricultural sector of the country was a deep food crisis. In turn, the total shortage of meat and dairy products and bakery products in most regions of the country, which has become essentially chronic, has shown the complete failure of some managerial experiments of the First Secretary of the CPSU Central Committee.Conclusions. Deep unprofessionalism, paternalism, the desire to interfere and direct literally all spheres of the national economy of the country, from space exploration to agriculture — these qualities were inherent in most of the generation of party leaders of the USSR. Khrushchev's unceremonious intervention in the agrarian sphere led to serious negative economic and social consequences, a sharp decline in the party's authority in society, which continued in the following years after his departure from the political arena. In the end, in 1991, it was not so much the foreign and homegrown "enemies of Soviet power" that crushed a huge power, but above all, the inability of the country's party elite to solve the most pressing problems of Soviet people.

Authors: Kostyuk Alexander
Published: December 2022

This issue of Corporate Governance and Sustainability Review considers sustainability from various aspects: significantly increased attention to such areas as preparation of materials for the board meeting, search by directors for information as a supplement to
the information provided by the executive management, and improvement of the effectiveness of the board chairman’s meetings. Research published in this issue contributes to the previous literature by Akomea-Frimpong, Asogwa, and Tenakwah (2022), Owusu (2021), Kostyuk, Mozghovyi, and Govorun (2018). and defines the new horizont for the future research outlined by the scholars to the same extent before (Gamal, Wahba, & Correia, 2022; Helfaya, 2022; Singh & Rahman, 2022; Lester, dela Rama, & Crews, 2021; Sveen, Gresaker, Hæhre, Madsen, & Stenheim, 2020; Grove & Clouse, 2018).
Numerical Calculations of the MEW Equation from a New Perspective
Authors: Karta Melike , KUTLUAY Selcuk
Published: December 2022

Numerical computations for natural systems and acquiring travelling wave
solutions of nonlinear wave equations in relation to sciences such as
optics, fluid mechanics, solid state physics, plasma physics, kinetics,
and geology have become very important in the field of mathematical
modeling recently. For this, many methods have been suggested. The
strategy applied for this article is to obtain more perfect numerical
solutions of Modified Equal Width equation (MEW), which is one of the
equations used to model the nonlinear phenomena mentioned. For this
purpose, the Lie-Trotter splitting technique is applied to the MEW
equation. Firstly, the problem is split into two sub-problems, one
linear and the other nonlinear, containing derivative with respect to
time. Secondly, each subproblem is reduced to the algebraic equation
system by using collocation finite element method (FEM) based on the
quintic B-spline approximate functions for spatial discretization and
the convenient classical finite difference approaches for temporal
discretization. Then, the obtained systems are solved with the Lie
Trotter splitting algorithm. Explanatory test problems are considered,
showing that the newly proposed algorithm has superior accuracy than
previous methods, and the numerical results produced by the proposed
algorithm are shown in tables and graphs. In addition, the stability
analysis of the new approach is examined. Therefore, it is appropriate
to state that this new technique can be easily applied to partial
differential equations used in other disciplines in terms of the results
obtained and the cost of Matlab calculation software.

is outstanding and unique.
Effects of grazing intensity on richness and composition of rhizosphere and non-rhizosphere microbial communities in a semiarid grassland
Authors: Yang Yang , Hao Zhang , Wei Liu , Jiamei Sun , Zhao Mengli , Han Guodong , Pan Qingmin
Published: December 2022

1.Overgrazing-induced grassland degradation has become a severe
ecological problem worldwide. The diversity and composition of soil
microbial communities are responsive to grazing disturbance. Yet, our
understanding is limited with respect to the effects of grazing
intensity on bacterial and fungal communities, especially in plant
rhizosphere. 2.Using a long-term (15 years) grazing experiment, we
evaluated the richness and composition of microbial communities in both
rhizosphere and non-rhizosphere regions, under light, moderate, and
heavy intensities of grazing, in a semiarid grassland. We also examined
the relative roles of grazing-induced changes in some abiotic and biotic
factors in affecting the richness and composition of microbial
communities. 3.Our results showed that the responses of soil bacteria to
grazing intensity differed greatly between rhizosphere and
non-rhizosphere, and so did soil fungi. Specifically, the bacterial
richness decreased markedly under moderate and heavy grazing in
rhizosphere soil, whereas little impact on the fungal richness was
observed. For microbial composition, with the increase in grazing
intensity, an increase in dissimilarity among bacterial communities was
observed, and this trend also held true for the fungal communities.
Hierarchical partitioning analyses indicated that the bacterial
composition in rhizosphere was primarily driven by root nitrogen and
soil nitrogen concentrations while that in non-rhizosphere by soil
available phosphorus. In addition, soil available phosphorus played an
important role in affecting the fungal composition in both rhizosphere
and non-rhizosphere regions. 4.Synthesis: This study provides direct
experimental evidence that the richness and composition of microbial
communities were severely altered by heavy grazing in a semiarid
grassland. Thus, to restore the grazing-induced, degraded grasslands, we
should pay more attention to the conservation of soil microbe in
addition to vegetation recovery.
Some results for a system of NLS arising in optical materials with χ3 nonlinear response
Authors: Duan Yingxin , Zhang Guoqing
Published: December 2022

In this paper, we investigate the nonlinear Schödinger equations with
cubic interactions, arising in nonlinear optics. To begin, we prove the
existence results for normalized ground state solutions in the L 2
-subcritical case and L 2 -supercritical case respectively. Our proofs
relies on the Concentration-compactness principle, Pohozaev manifold and
rearrangement technique. Then, we establish the nonexistence of
normalized ground state solutions in the L 2 -critical case by finding
that there exists a threshold. In addition, based on the existence of
the normalized solutions, we also establish the blow-up results are
shown by using localized virial estimates, and a new blow-up criterion
which is related to normalized solutions.

Published: December 2022

Background: Childhood cancer survivors need regular, long-term
survivor care. The Children’s Oncology Group (COG) recommends that
pediatric cancer patients receive ongoing, evidence-based surveillance
for late-effects beginning two years after cancer therapy completion. A
third of survivors are not engaging in long-term survivorship care. This
study assessed barriers and facilitators to follow-up survivorship care
through the perspectives of pediatric cancer clinic representatives.
Methods: As part of a hybrid implementation-effectiveness
trial, a representative from 12 participating pediatric cancer survivor
clinics completed a survey about site characteristics, and a
semi-structured interview on barriers and facilitators to survivor care
delivery at their institution. Interviews were grounded in the
socio-ecological model (SEM) framework and utilized a Fishbone diagram
to identify the root causes of a problem. We ran descriptive statistics
and conducted thematic analyses of the interview transcripts to create
two meta-Fishbone diagrams. Results: Participating clinics
(n=12) have existed for at least five years (mean=30, range= 5-97), and
half (50%) report seeing 100-200 survivors annually. In the Fishbone
diagram, top facilitators were in the SEM domain of Organization,
specifically with familiar staff (100%), resource utilization (92%),
survivorship-exclusive staff (83%), and clinic processes (83%). Common
barriers were in the domains of Organization, Community, and Policy
which included technology limits (92%), scheduling issues (92%),
insufficient funding/insurance (92%), and distance/transportation
(100%). Conclusion: Using the Fishbone diagram was
instrumental in understanding multilevel contextual issues related to
survivor care delivery for pediatric cancer clinics. Future efforts can
develop education, processes, and services to promote cancer follow-up
care.

Published: December 2022

Today, the elderly population is increasing and they endure many
drawbacks, especially defects in their knee joints which lead to
improper gait. To solve this problem, their knee joint can be replaced
with knee arthroplasty. In this letter, the level of improvement in the
human gait before and after total knee arthroplasty (TKA) surgery is
investigated using the Dynamic Time Wrapping (DTW) algorithm. For this
purpose, several volunteers who have problems with their knees
incorporate in a test before and after TKA surgery, and data of gait
analysis is collected. Then, the obtained data is compared with a
reference using the DTW algorithm. The outcome results illustrate an
improvement of 89\% - 97\% by the
proposed algorithm after TKA surgery. Therefore, patients can see
improvement with high speed and accuracy that result in more promising
for using TKA surgery.

Authors: yang zhiyong , wang fan , Chen Hongwei , liu xing , Zhang Daode
Published: December 2022

To make the snake robot crawl quickly along the high-voltage cable, this
paper employs the Simulated Annealing Algorithm (SAA) to find the
optimal step size for the spiral-winding gait of the snake robot and
improve its crawling speed along a high-voltage cable. First, a robotic
spiral-winding gait is designed based on a snake-like robot
configuration and the crawling environment along a wire. Next, the
double-chain Hopf oscillator is used to generate the spiral-winding gait
for the snake-like robot. After that, based on the snake robot’s
position, the SAA is employed to improve the crawling speed of the snake
robot by finding the optimal step size of the spiral-winding gait.
Finally, the CoppeliaSim software is used to analyze the optimization
effect of the speed of the snake robot crawling along the wire. The
results highlight that the maximum crawling speeds of the snake robot
are 0.8868 cm/s, 0.8843 cm/s, 0.8598 cm/s, and 0.7971 cm/s, which are
18.01%, 8.16%, 11.01%, and 12.16% lower than the maximum speed
obtained using the sampling fit method when the wire friction
coefficients are 0.3, 0.4, 0.5, and 0.6. This simulation results verify
the effectiveness of the optimized control algorithm.

Published: December 2022

Background: Rapid antigen tests have emerged to deal with the Covid 19
pandemic. Rapid diagnosis of SARS-CoV-2 infection is essential to reduce
the spread of the disease. The aim of this study was to estimate the
prevalence of COVID-19 infection in Temara-Skhirat in symptomatic young
adults through PANBIOS® test Methods: A prospective observational
prevalence was conducted at the center in September 2021. Two
investigators participated in data collection which included all
symptomatic young adult patients. The diagnostic performance of the
PANBIOS® and the PCR was carried out with the JAMOVI to calculate the
sensitivity and the specificity. Results: Among 206 symptomatic
participants, the mean age was 38 ± 12 years and majority were women
59%. 80% of the population had benefited from the anti-covid vaccine.
The median duration of symptoms was 4 days; the most common symptoms
were respectively fatigue 62%, headache 52%, fever 48%, cough 34%,
loss of smell 25%, loss of taste 24%, sore throat 22%. Results
revealed 23% of positive covid tests carried out with the PANBIOS® test
vs 30% with the PCR test. The calculated medical decision between PCR
vs PANBIOS® test showed a very high specificity of 95.7% and a
sensitivity of 69.4%. There was a concordance between the PANBIOS® test
and the PCR. Conclusion: The sensitivity and specificity of the PANBIOS®
vs PCR test are similar to those described in WHO recommendations. It is
a Useful test for controlling the spread of Covid 19 allowing
identification of active infection and isolation of positive patient
The Specific Value of Upgrading to Left Bundle Branch Pacing in Patients with Pacing-Induced Cardiomyopathy or Non-Pacing-Induced Cardiomyopathy: A Retrospective Study
Authors: Wang Min , Shan Yu , Lin Maoning , Sun Yaxun , Zhang Jiefang , Jiang Hangpan , Fu Guosheng , Zhang Wenbin
Published: December 2022

Aims: Left bundle branch pacing (LBBP) upgrade can improve
cardiac function and clinical outcomes in patients with pacing-induced
cardiomyopathy (PICM), but the specific value especially compared with
the level before right ventricular pacing (RVP) in patients with PICM
and non-pacing-induced cardiomyopathy (Non-PICM) is still unknown.
Methods: This study retrospectively enrolled 108 patients with
LBBP upgrade (38 patients with PICM and 70 patients with Non-PICM). PICM
patients were defined as patients who had a normal left ventricular
function and a > 10% decrease in LVEF after RVP, among
patients experiencing > 40% RVP, when other organic heart
diseases were excluded. Non-PICM patients were defined as patients
requiring pacemaker upgrades with non-decreased cardiac function
reasons, such as battery exhaustion, pacing system infection, and right
ventricular lead failure. All upgrade patients experienced three stages:
before RVP (Pre-RVP), before LBBP upgrade (Pre-LBBP), and after LBBP
upgrade (Post-LBBP). QRS duration (QRSd) , lead parameters,
echocardiographic indicators, and clinical outcomes evaluation were
recorded at multiple time points. Univariable analysis of variance and
Mann-Whitney U-tests for repeated measures were used to assess the
effects of the LBBP upgrade. Results: At the follow-up of 12
months, for PICM patients, left ventricular ejection fraction (LVEF)
significantly increased from 36.6 ± 7.2% at Pre-LBBP to 51.3 ± 8.7%
after LBBP upgrade (P < 0.001), and left ventricular
end-diastolic diameter (LVEDD) significantly decreased from 61.5 ± 6.4mm
at Pre-LBBP to 55.2 ± 6.5mm after LBBP upgrade (P < 0.001),
besides, New York Heart Association (NYHA) classification improved from
3.16 ± 0.82 at Pre-LBBP to 1.76 ± 0.88 after LBBP upgrade (P <
0.001), but they all failed to restore the level of the initial status
before RVP (LVEF: 51.3 ± 8.7% vs 60.3 ± 7.6%, P < 0.001)
(LVEDD: 55.2 ± 6.5mm vs 49.7 ± 6.1mm, P < 0.001) (NYHA:1.76 ±
0.88 vs 1.11±0.31, P < 0.001). Furthermore, for PICM patients,
the number of moderate-to-severe heart failure (HF) (NYHA III-IV) and
diuretics used after the LBBP upgrade also could not restore the level
before RVP (P = 0.002 and P = 0.004). At the follow-up of 12 months,
Non-PICM patients after the LBBP upgrade had no significant improvement
in LVEF, LVEDD, NYHA classification (LVEF: P = 0.521; LVEDD: P = 0.383;
NYHA classification: P = 0.279) and no difference compared with Pre-RVP
(LVEF: P = 0.559; LVEDD: P = 0.952; NYHA classification: P = 0.942).
Conclusion: LBBP upgrade effectively improved the cardiac
function and clinical outcomes in PICM patients but failed to restore
the functional levels before RVP. For Non-PICM patients, the cardiac
function and clinical outcomes after the LBBP upgrade had no significant
difference when compared to Pre-RVP and Pre-LBBP.
Temperature Effects on the Power Characteristics of Vertical-Cavity Surface-Emitting Lasers (VCSELs)
Authors: Hisham Hisham , Mahdi Adzir , Fauzi Ahmad
Published: December 2022

A numerical analysis on temperature variation effects on the output
power (Pout) characteristics of vertical-cavity surface-emitting lasers
(VCSELs) is presented in this paper. While previous works in the
literature mostly omitting the thermal effects. The effects have
investigated according to the temperature dependence (TD) of the VCSEL
parameters instead of the well-known Pankove empirical relationship.
Also, unlike many previous studies, the thermal effects on the Auger
process (C) were taken into account and were not neglected. Besides the
temperature, the impact of laser cavity volume (Va (i.e D, L, d)), the
injection current (Iinj), and the quality of mirror reflectivity (R)
also have investigated. Results showed that the rate of decreasing the
Pout with the increase of the temperature has increased with the
increase of the D value compared with the L or d value. In contrast,
results shown that the TD of the C is affects the VCSEL performance and
it is not correct to neglect its influence. Also, results showed that
increasing the Iinj value does not lead to a significant increase in the
thermal effects on the Pout. On the other hand, increasing the R value
will lead to a significant reduction in the thermal effects and it may
be dampening its behavior. Conversely, there is no significant effect
when the increase in R value is above 95%.

Authors: Jamshaid Warda , Jamshaid Maryam , Muzaffar Jameel , Nieto Hannah , Coulson Chris , SHARMA Neil
Published: December 2022

Background: Intra and post-operative blood loss is a major risk in head
and neck (H&N) surgery. Recently the use of tranexamic acid (TXA) has
been investigated by multiple studies for reducing intra and
post-operative bleeding, however reported results are variable.
Objectives: To determine the safety and efficacy of tranexamic acid use
in Head and Neck surgery. Methods: Systematic review of MEDLINE, EMBASE,
CINAHL, Cochrane Library, PubMed, ClinicalKey and Clinicaltrials.gov
according to the PRISMA guidelines. Studies were included if they
reported on intraoperative bleeding, volume or duration of
post-operative drain or return to theatre rate for post-operative
haemorrhage in adult populations following use of TXA. Risk of bias
assessment with Cochrane Risk of Bias (RoB2) tool for RCTs and NOS tool
for non-randomised studies. Results: 16 studies were identified (114,
407 patients). 8 studies evaluated TXA in major H&N surgery and 8
studies in tonsillectomy. Primary outcomes were reduction in
intraoperative or post-operative bleeding. Secondary outcomes included
the duration of post-operative drain placement and return to theatre
rate. No adverse events were reported in any patients. TXA is effective
in reducing intra-operative blood loss in tonsillectomy. However, the
effect on post-tonsillectomy haemorrhage was unclear. Insufficient
evidence exists of benefit of TXA on intra-operative bleeding in major
H&N procedures. Post-operative bleeding rates were substantially
reduced in most major H&N studies. The duration of drain placement and
risk of blood transfusion was unchanged in most cases. Conclusion: TXA
use is safe in H&N patients. Whilst sufficient evidence exists to
support the use of TXA in tonsillectomy, insufficient evidence exists to
recommend use in major H&N surgery. Key words: Tranexamic acid, Head
and Neck surgery, thyroidectomy, tonsillectomy

Published: December 2022

Bulk products of crystalline Bi2Se3-xTex alloys (x =0.0, 0.1, 0.3, 0.5) were prepared using simple melting synthesis. Crystalline features, microstructure, and surface morphologies of the synthesized samples were examined via X-ray diffraction, scanning electron microscope, and energy dispersive X-ray spectrometer. Elemental distribution was studied by energy dispersive analysis of X-ray spectroscopy. Polycrystalline of rhombohedral crystal structure was observed for the concerned samples. Perfect crystallinity and micro-scalability of the prepared were also reflected by the physic-chemical properties of each sample. Thermal behavior was studied throughout differential scanning calorimetry and thermo-gravimetric analysis showing that the samples are of high stability over high temperature range. Physic-chemical properties were determined in terms of experimental density. These properties were compactness value, molar volume and the percentage of free volume. Density of Bi2Se3 alloy was obtained at 7.37 gm/cm3. The Te doping enhanced the density of the Bi2Se3-xTex system. The most Te doped alloy showed density of 9.018 gm/cm3. All other physic-chemical properties showed strong dependence on the Tea amounts in the system.

Published: December 2022

Heusler-type Fe2AlVxTi1-x alloys offer an alternative solution for the generation of thermoelectric power near room temperature. In the current research, thermoelectric properties of the p-type Fe2AlV0.9Ti0.1 and Fe2AlV0.9Ti0.1/CNT alloys, prepared by SPS, were studied. Carbon nanotubes (CNT) were used as dopants to improve the seebeck coefficient and electrical conductivity. Upon doping with CNT, the thermal conductivity was significantly reduced, meanwhile, the value of the power factor increased from 0.45 to 1.55 mW/mK2 at around 330 K. The effect of CNT inclusions on the thermoelectric parameters of Fe2AlVxTi 1-x compounds was systematically studied. When compared to Fe2AlV0.9Ti0.1, which had a figure of merit of just 0.02 at 330 K, the CNT-containing samples showed a significantly improved figure of merit up to 0.07. We offer a novel technique to improve the performance of Fe2AlV alloys.
Bee Diversity Associated with Canavalia rosea (Sw.) DC. (Fabaceae, Papilionoideae) in an Peri-Urban Patch of “Restinga”
Authors: Araújo Vinícius Albano
Published: December 2022

The Restinga is one of the physiognomies of the Atlantic Forest biome with the highest degree of anthropic impact, mainly due to disordered urbanization. The impacts generate habitat loss and threaten the animals and plants that inhabit this ecosystem. In the Restinga, the psammophilous vegetation have an important role in stabilizing the sandy substrate and maintaining the pollinator community. In this study, we analyzed the floral resources offered by Canavalia rosea to floral visitors between October 2019 and September 2020, in the Municipal Natural Park of Barreto’s Restinga, in Macaé, Rio de Janeiro, Brazil. Sampling was carried out from 8:00 am to 4:00 pm, covering a 250-meter transect in the sandy cord, counting the total number of open flowers and collecting visiting bees. The morphology of C. rosea flowers was described to relate to the functional traits of visitors, related to pollen and nectar collection. The pollen load of visitors was analyzed to estimate the degree of specialization in relation to C. rosea. A total of 192 individuals of 14 bee species were captured. There was a significant relationship between the availability of floral resources, measured by the number of open flowers and the richness and abundance of bees. The greatest richness of bees was observed between January and March and the greatest abundance in January. The most frequent visiting genera in C. rosea were Eufriesea, Centris and Xylocopa. The greatest richness of pollen types was observed in Eufriesea species. Most Xylocopa individuals showed C. rosea pollen. In this study, the importance of C. rosea as a source of floral resources for fourteen species of solitary bees was demonstrated. The data generated increases the knowledge about the ecological patterns of C. rosea and its floral visitors and may contribute to the maintenance and expansion of Restinga areas in urban environments.
Subcutaneous Ureteral Bypass Device for Treatment of Ureteral Obstruction in Persian Breed Female Cat
Authors: Errante Paolo Ruggero
Published: December 2022

In the recent years, benign ureteral obstruction by nephrolithiasis has an increased incidence in the feline population, whose causes are not yet fully established. Its diagnosis is based on clinical signs, biochemical analyzes and imaging methods such as radiography and ultrasound. For its treatment, initially one can resort to pharmacological therapy. However, when this is ineffective or contraindicated due to the risk of deterioration of the renal condition, there is a need for surgical intervention. Currently, the subcutaneous ureteral bypass implantation technique is being used more frequently, despite the high cost and periodic mainitance of system functionally. In this case report, we describe the implantation of the subcutaneous ureteral bypass system in a 9-year-old Persian breed female cat with azotemia associated with total obstruction of the right ureter and partial obstruction of the left ureter by nephrolithiasis. In function of total obstruction of right ureter lumen and risk of total obstruction of left ureter lumen was decided by immediate surgery intervention with use of subcutaneous ureteral bypass system. After the implantation of the subcutaneous ureteral bypass system, there was disappearance of azotemia and improvement in the clinical picture and quality life of the cat female.
Note about the New Distribution Area of Atlantoxerus getulus LINNAEUS, 1758 ( Mammalia, Rodentia ) in Algeria
Authors: Ahmim Mourad
Published: December 2022

A rodent of the family of the Sciuridae, the Barbary ground squirrel Atlantoxerus getulus is one of the 111 species of mammals living in Algeria, it is listed in the IUCN Red List as "Least Concern". It is the only species of squirrel to inhabit Africa north of the Sahara in arid rocky ground at the South Western of Algeria and Morocco. It is a small colonial species growing to a length of between 160 and 220 millimetres with a bushy tail of a similar length. It weighs up to 350 grams and has short wiry hair and its belly is paler grey and the tail is longitudinally barred in black and grey. It feeds on plants and a major part of its diet is the fruit and seeds of the argan tree (Argania spinosa). Initially since 1991 several authors stipulated that the species is only present in the western part of Saharan Atlas from the Moroccan border to the vicinities of Bechar ( Labiod Sidi cheikh, Bechar, Ain Sefra ). Recently the species was observed in the Targent locality near Tindouf distant of 807 km from Bechar, 1191 km from Labiod Sidi Cheikh, and 1057 km from Ain Sefra . This is the first time this species has been reported in this region, this led us to suggest that its range has extended to the South West and further studies of its ecology in this new area is recommanded.

Authors: Suluku Roland
Published: December 2022

Background: There is a paradigm shift in the uses of goats during the twenty-first century. In time past, people raise goats for prestige and festivals. Today, people rear goat for financial, spiritual, cultural, religious, mental and sacrificial purposes. Goat rearing has become a major source of income in Africa and Sierra Leone in particular. Goats are primary and immediate source of cash when it becomes herculean to get diamonds during mining. The illicit miners sacrifice brown goats before and during extraction to appease the spirits. Goat rearing becomes the industrial life -supporting machine for vast majority of illicit diamond miners and other business people in Tongo Field. Peste des Petits Ruminant is the major disease affecting most of the goats in Tongo Field. The study investigates the socioeconomic impact of Peste des Petits ruminant on goat farmers engaged in diamond mining in Tongo Field. The Objective: The objective of the research is to investigate the uses and measure the socio-economic impact of PPR disease on goat farmers in six sections in Tongo field Method: A semi-structured questionnaire was administered to 10 randomly selected household heads in each of the six sections. A blind ballot selector dips into a bag and select a number designated to receive questionnaire for interview.

Authors: Amin Omar M
Published: December 2022

Specimens of Pseudoglaridacris confusus (Hunter, 1929) nom. nov. (Caryophyllidae) first described as Glaridacris confusus Hunter, 1929 and subsequently designated as Pseudoglaridacris confusa Oros, Uhrovič, Scholz, 2018 were collected and examined from 3 species of buffalofish, Ictiobus cyprinellus (Valenciennes), I. bubalus (Raf.), and I. niger (Raf.) in 2 Arizona lakes, Roosevelt and Apache lakes, on the Salt River, Arizona. We update our first and only 1969 redescription of this Arizona population, with new observations and measurements, compare with those in the original description, and assess the status of P. confusus in light of the recent taxonomic treatments of this species. The morphology of P. confusus is revisited using light microscopy revealing new features. Emphasis is placed on the morphological variability of its scolex. The re-examination of over 50 specimens from the Apache and Roosevelt lakes provided an opportunity to revise the taxonomy of the species and correct and update some old statements and concepts by other observers.
Study of the Viability of Oocytes Collected from Bovine Ovaries Obtained in a Slaughterhouse Under Punctured at Different Times
Authors: Palmeira-de-Oliveira Ana
Published: December 2022

Due to the reduction of use of live animals, for ethical reasons, in studies for reproductive toxicological evaluation of new compounds and ingredients, the use of biotechnology of in vitro maturation of bovine oocytes (bIVM) is a relevant procedure, as it uses slaughterhouse material. To optimize the implementation of this procedure in an animal fertilization facility, in this study we evaluated the feasibility of using bovine oocytes, punctured at different times, from ovaries discarded at the slaughterhouse. We found an overall maturation rate of (86±7%) (mean±SD), which is like maturation rates already described for this method. Moreover, we found no significant difference between the average maturation rates of bovine oocytes obtained from ovaries punctured at the slaughterhouse (88±8%) and the ones obtained from ovaries punctured at the laboratory, after transport (85±6%). We found statistically significant differences when considering the average maturation rates determined in our study by grouping the animals in two different age groups. Moreover, since no statistically significant differences were observed regarding the two different methodological approaches, we assume that puncture at the laboratory following transport is a better option, since the puncture is performed in cleaner, more convenient and controllable environment a more clean, convenient and controllable environment. We conclude that using material obtained from the slaughterhouse is an adequate methodology to implement in vitro bovine maturation procedures in an animal fertility laboratory, namely, to assess reproductive toxicity of testing compounds in gametes.

Technology plays an important role in life. Information and Communication Technology (ICT) has expanded educational options by enabling teachers and students to use technology to reorganize existing education and training systems. An adequate number of studies have identified the various benefits of implementing e-learning. However, not all institutions that implement online learning get the expected results. In addition, teachers in schools are not homogeneous. This study analyzes e-learning readiness in rural areas during the Covid-19 pandemic. This type of research is descriptive and quantitative. The subjects of this study were ten teachers, three IT staff, two foundation administrators, and 87 students from elementary and junior high schools. Data was collected using questionnaires and interviews. Data were analyzed using Aydin and Tasci's E-Learning Readiness Score, which describes learning outcomes. The results of this study indicate that overall, e-learning is ready to be implemented due to the leadership's commitment in the form of funds and policy support for the implementation of e-learning. Factors that need serious attention are technology infrastructure, human resources, and content.

In-Service Teachers’ Performance Using Guided Inquiry Computer Simulations to Learn Cellular Respiration
Authors: Kibirige Israel
Published: December 2022

Respiration is one of the difficult biology topics, and teachers have challenges effectively teaching it to minimise misconceptions. The aims of this study was to analyse the effect of guided inquiry computer simulations on pre-service teachers' performance. A quasi-experimental design was used with 65 in-service teachers: 33 experimental groups taught using guided inquiry computer simulations, and 32 control groups received instructions using traditional chalk-and-talk. Data were collected using the Academic Performance Test and analysed using a T-test to determine the differences between the groups. Analysis of Covariance was used to find out the effect of the intervention. Both groups were pre-tested to gauge their previous knowledge and post-tested to establish changes after the teaching. The results show experimental group surpassed the control group. Also, males and females performance in the experimental group was similar, suggesting that guided inquiry computer simulations favoured both genders. It implies that guided inquiry computer simulations are effective tools to minimise misconceptions regarding cellular respiration. Thus, the researchers recommend using guided inquiry computer simulations in qualitative and quantitative approaches with a large sample of in-service teachers from different geographic regions.

The position of reason is very important in human life, even the Qur'an also teaches humans to always use their minds correctly and well, so that with good reason, humans will be more noble, moral, moral, educated and valuable compared to other creatures. and benefit both himself and others. Therefore, it is necessary to know the concept of reason contained in the Qur'an, so that with these concepts it will be easier for humans to develop their basic potential to become superior human beings. This research is a type of literature study, the data sources in this study are divided into two, namely primary and secondary. This research is qualitative in nature, in data processing, the authors used descriptive qualitative data analysis techniques with an interpretive approach and with three data analysis methods, namely inductive, deductive, and comparative. The results of the research show that there are three concepts of reason that can be used as basic human potential to become a superior human being directly mentioned in the Qur'an, namely: 1) Tazakkur, 2) Nazara, and 3) Tadabbur. The three concepts of reason according to the Qur'an can be used as development of human potential, especially basic potential. However, there are other concepts of reason that can be used as the basic potential of humans to become superior humans, such as Tafaqquh, Tafakkur, Ta'aqqul, and Fahima. However, these concepts of reason are not mentioned too much repeatedly compared to the three concepts of reason mentioned in this study.
