Authors: Panse Neha Amey , Kale Jyoti , Khondalay Priyanka Praphulchandra
Published: November 2021

: Propofol has been used since ages as induction agent to aid in insertion of Supraglottic airway devices however its side effects like hypotension, apnea and pain on injection do coexist. To avoid these side effects sevoflurane has been studied and well recognized because of its sweet smelling property. We conducted this study with primary aim to compare the insertion conditions such as no. of attempts for insertion, hemodynamic variations and awakening after surgery. The secondary aim was to note the adverse effects associated with Sevoflurane and propofol.

We included sixty female patients of age 18-65 years graded as ASA I and II undergoing short gynecological procedures. Patients were induced with Sevoflurane 8% or IV Propofol 2mg/kg. Attempts for I-gel insertion, jaw relaxation, biting, coughing, gagging, laryngospasm and hemodynamic pressor response and awakening after surgery were noted.

Induction time with Propofol is less compared to Sevoflurane. I-Gel insertion time with Sevoflurane and Propofol is insignificant (p value= 0.93). 25 patients in Group S and 27 patients in group P had very easy insertion of I-gel. 23 patients in Group S and 27 patients in Group P had relaxed jaw. None of the patients in both groups experienced laryngospasm.

Propofol provided better conditions for I-gel insertion with manageable hypotension while the patients induced with Sevoflurane were hemodynamically more stable but the jaw relaxation was less as compared to that provided by propofol. Induction with 8% Sevoflurane by Vital Capacity Breath (VCB) technique can be an alternative for induction in high risk patients. Also the awakening from anaesthesia is faster with sevoflurane and is more suitable for patients demanding early discharge after day care surgeries.

Published: November 2021

Epidural analgesia is the most commonly used method for surgical anesthesia, obstetric analgesia, post-operative pain control, and chronic pain management. These epidurals are used either as a single-shot technique or with the catheter that allows intermittent boluses or continuous infusion, or both. All of these variables are controlled by choice of drug concentration, dosage, and level of injections.

To compare the onset and duration of sensory block, motor block, and post-operative analgesia duration using Ropivacaine with Tramadol and Ropivacaine with Midazolam in the Epidural technique.

In this prospective, non-randomized, comparative study, the total of 160 patients who underwent surgeries below the umbilicus did under epidural technique at Govt. Kilpauk Medical college hospital a Govt. Royapettah hospital, Chennai, was screened. Patients were divided into two groups. Patients in Group R received an epidural injection of 0.5% Ropivacaine (30ml) with Tramadol 2 mg/kg, whereas patients in Group L received an epidural injection of 0.5% ropivacaine (30ml) with Midazolam (50mg/kg).

On studying the comparison of the onset of sensory, motor blockade, and duration of the sensory-motor blockade in the two groups, the onset of sensory blockade, motor blockade, and duration of motor blockade was more among ropivacaine with midazolam group. In comparison, the duration of sensory blockade was more among ropivacaine with tramadol group. A statistically significant difference in onset of sensory, motor blockade, and duration of sensory blockade across the group was found (p<0.005).

Tramadol or Midazolam's addition to caudal epidural block with ropivacaine showed significant prolongation of post-operative analgesia compared to ropivacaine alone. The mean duration of analgesia was more among ropivacaine with the Tramadol group.

Authors: Gour Vinayak , Dangi Vimal , Verma Sushil Chand
Published: November 2021

: Preanesthetic medication is important among the paediatric patients undergoing surgeries. A good preanesthetic medication reduces the anxiety and the post-operative pain among paediatric patients.

A randomised controlled trial was done to compare the two groups of Dexmedetomidine, and Midazolam given as preanesthetic medication intranasally.

: Both the groups had comparable baseline values before premedication but there was a significant difference in the vital parameters of heart rate and systolic blood pressure after medication. The mean Parental Separation Anxiety Scale was found to be 1.4 ± 0.85 and 2.5 ± 0.98 among Dexmedetomidine and Midazolam group respectively. This was found to be significant (p < 0.001).

Dexmedetomidine when given as preanesthetic medication intranasally significantly controls the vitals within the normal range and produces better parental separation anxiety scores and mask acceptance scores as compared to Midazolam.

Published: November 2021

Caesarean section was the first obstetrical operation that saves the life of the baby when normal delivery fails. Spinal anaesthesia is the most appropriate method for caesarean section. But hypotension is the most common side effect of it in patient with pregnant uterus.

To compare the vasopressor effects of ephedrine and phenylephrine in ameliorating hypotension in elective caesarean delivery receiving crystalloid coloading, during intrathecal bupivacaine injection.

: Study participants were randomly divided into two groups of 50 patients each. After subarachnoid block, all the parturients were given rapid administration of ringer lactate solution 20ml/kg, during the initial 5 minutes of surgery the parameters such as oxygen saturation, blood pressure and pulse rate recorded for every one minute followed by every five minutes until the completion of the surgery. The incidence of hypotension, bradycardia, nausea/vomiting, block height and requirements of vasopressor (ephedrine and phenylephrine) were recorded. Apgar score, and blood sample from umbilical cord was taken and sent for blood gas analyses to determine the neonatal outcome.

: Vasopressor consumption was more in phenylephrine group (92±112 µg) compared to ephedrine group (4.8±5.5 mg) which was statistically significant p=0.0001. The neonatal outcome was statistically significant regarding umbilical cord pH (Group E-7.2±0.06 and Group P-7.37±0.04 with p=0.002) but clinically no true fetal acidosis in either groups and no significant changes regarding Apgar score in the two groups.

: Thus we conclude that that ephedrine 6 mg and phenylephrine 100 µg does not differ in their efficacy to manage hypotension during spinal anaesthesia for caesarean delivery. However, maternal bradycardia was more in the phenylephrine group with equal incidence of fetal acidosis in the study groups.

Published: November 2021

The key component of Enhanced recovery after cesarian section (ERAC) is to improve maternal and child outcome and enhance recovery by dint of effective non opioid based pain control. We aim to compare the efficacy of Transverse abdominis plane (TAP) block with local wound infiltration for postoperative analgesia in cesarian section (CS).

Eighty-two patients undergoing caesarean section under spinal anaesthesia were randomized to undergo local wound infiltration(Group I) (n=41) versus landmark guided bilateral TAP plane block (Group T) with 20ml of 0.25% levobupivacaine postoperatively Each patient was assessed post-operatively by a blinded investigator at regular intervals up to 24 h for visual analogue score (VAS). Requirement of analgesia, patient satisfaction, time for the first and second rescue analgesia, and the incidence of side effects was also noted.

The median VAS was more in the group I compared to group II and was statistically significant (p=0.0032). The mean time to first rescue analgesia was prolonged in group I (4.060 ± 0.682 hrs) compared to group T (3.302 ± 0.519 hrs)(P< 0.001). The mean total analgesic requirement in 24 hours was reduced in group T (89.63 ± 41.82) as compared to group I (137.2 ± 33.13) (P<0.001. Group (T) compared to group I patient had a higher mean patient satisfaction score (1.487 ± 0.589) (2.097 ± 0.430) respectably (P < 0.001).

TAP block provides better quality of analgesia and can be safely incorporated as a part of multi-model analgesic regimen postoperative pain over local infiltration in cesarian section.

Authors: Kostrhunova Dagmar
Published: November 2021

This contribution defines the conflicts that international migration brings in connection with the increased number of applicants for recognition of foreign education in the Czech republic. The migration of people has been increasingly observed since the so-called Arab Spring 2011 until now. Globalization or connecting the whole world is a current trend that people are learning to accept. Each country receiving migrants determines its own strategy, rules, and approach to migration. „It is estimated that today about 150 million people live outside their homeland“ (Siskova, 2001: 18). With the increased migration and globalization, there has been an increased number of applicants in the Czech Republic for the recognition of education, serving mainly for further higher education. At the same time, for gaining job opportunities, for using foreign experience and, last but not least, for finding better living conditions. „The main determinants of human movements can be considered differences in the wealth of individual economies, living standards and stability in given societies“ (Siskova, 2001: 19). The aim of the contribution is to get acquainted with the basic concepts of migration and migration policy in connection with the recognition of education in the Czech Republic from foreign countries and whether increased migration of persons related to the recognition of foreign education and the acquisition of further education of foreigners in the Czech Republic.

Influence of the Manufacturing Accuracy of the Planetary Cycloid Gear on the Positioning Accuracy of the Parallel Robot
Authors: Palochkin S.V. , Sinitsyna Y.V. , Erastova K.G.
Published: November 2021

The increased accuracy in high-speed positioning of the parallel robot effector in comparison with that of serial robots with a sequential structure is often the main reason for their use in various modern industries, such as the manufacture of printed circuit boards for microelectronics. However, despite the higher theoretical positioning accuracy, due to the kinematic structure of the parallel robot, in practice this characteristic largely depends on the accuracy of manufacturing individual elements of this mechanism, the most important of which are the gearboxes of the drives of its input pairs. A solution to the urgent problem of determining the effect of the manufacturing accuracy of planetary pinion gearboxes included in the drive of a five-link parallel robot on the positioning accuracy of its output link is proposed. A specific relationship has been determined between the grade of accuracy number of the gear part dimensions and the robot positioning accuracy. The unevenness of the positioning accuracy along the coordinate axes of its working area is revealed. It was found that near the area of certain robot positions the accuracy of its positioning drops sharply.
Structural Synthesis and Analysis of Mechanisms with an Output Link Performing Two Rotational and One Translational Movements
Authors: Edakin A.I. , Edakina T.V. , Samoilova V.V. , Ramzhaev V.S.
Published: November 2021

The article considers mechanisms based on a hinged flat parallelogram with an additional link, ensuring the ability to maintain the insertion point of the tool installed on the output link. A rotational kinematic pair coupled to the base allows the plane of rotation of the articulated parallelogram to change the angle of inclination. The proposed design should have a greater load capacity than the available analogues, since the rotational kinematic pair mating the articulated parallelogram with the base is made in the form of two semi-axes, and the output link is located between the intermediate links of this parallelogram. The equality of the rotation angles of the output link and the intermediate links of the articulated parallelogram is ensured by the presence of additional links or belt drives. Three-dimensional models of these mechanisms are presented, and their structural synthesis is carried out in various modifications. Depending on the modification, it becomes possible to apply such mechanisms not only in industry, including additive technologies, but also in the field of medicine during surgical operations and in the study of plasma properties.

The article considers the results of multicriteria optimization of the unmanned aircraft composite wing. Minimum deflection, mass and normal stresses acting along the reinforcement directions are taken as optimization criteria. The thicknesses of the load-bearing frame elements and wing skin elements were selected as optimization parameters for three types of composites: carbon fiber reinforced plastic (CFRP) based on unidirectional carbon layers, CFRP based on carbon fabric layers, and fiberglass laminate based on E-glass fiberglass. A checking calculation of the optimal composite wing stability was performed using a geometrically nonlinear model. The calculation of the stress-strain state of the wing was performed using an anisotropic linear elastic material model. Calculations were carried out using finite element software packages ANSYS and FEMAP.

The quality of students who graduated from Nigerian universities and the role played by universities in the growth of society is a significant concern to every stakeholder. This study examined the impact of distributed leadership on the effectiveness of public universities and the mediating role of the quality administrative process. A correlational survey research design was adopted. A total of 450 lecturers were sampled and were given questionnaire of which 346 questionnaire were returned and, only 305 questionnaires were usable after the data cleaning. The results of the analysis showed that distributed leadership does not directly connect to institutional effectiveness. Furthermore, it is evident that administrative process intervenes in the correlation between distributed leadership and public university effectiveness. The findings imply that the various leaders at the unit level, departmental, faculty, and university-wide must ensure quality administrative processes to bring about the desired University system in the country.

Published: November 2021

In several universities in Indonesia, lecturers are accustomed to developing learning outcomes’ standards without the involvement of students in the formulation, although the students have many ideas about learning outcomes that are relevant to their needs. This study aimed to analyse the student learning outcomes’ standards in a disruptive era based on the students’ perspective from 9 faculties of several universities in Indonesia. The research method used was a quantitative approach, with 1059 student participants. Data were collected using a questionnaire with close-ended questions, and normality was analysed using the Shapiro–Wilk test and one-way analysis of variance test to determine the differences in learning outcomes’ standards between faculties. The achievements of disruptive learning at several universities in Indonesia are relatively high. However, there is an extreme distance in the level of disruptive learning achievement between faculties, due to the diversity of lecturers in understanding disruptive learning.

One of the world's leading social trends in development of higher education of the twenty-first century is progression of relationships between universities and business. The main purpose of this paper is to compare the models of integration between universities and business, considering the triple model of social partnership, the model with the dominant role of the state, and the model of mixed representation, typical for the Central European countries. The methodological framework of this research includes methods of statistical and comparative analysis and synthesis. From the results of this research, European higher education has developed and effectively operates the developed models of interaction between institutions of higher education and business. The obtained results allow us to evaluate the possibilities of applying positive foreign experience in Russian reality.

Nutritional Compositions and Sensitivity Analysis of Poultry Feed Mills in Bangladesh through Experimental Economics Approach
Authors: Islam Md Monirul
Published: November 2021

This research aimed at analyzing of nutritional compositions and resource use efficiency of poultry feeds covering Dhaka, Gazipur, Narsingdi, Kishoreganj and Mymensingh districts in Bangladesh. A total of 30 feed mills which categorized as high, medium and low quality on the basis of feed conversion ratio were selected purposively. The feed sample were collected during March 2013 to March 2014 and analysis by using AOAC, 2000 methods and KII. It is evident that a compound broiler feed of different feed manufacturers has differed between analytical value (AV) means laboratory test result and MV of various nutritional composition of ME value (energy). There is much difference in CP content which was lower than requirements and ME content was higher than requirements. The analytical value of EE (ether extract) was higher than manufacturer value which influence on human health. The results of sensitivity analyses clearly indicate that poultry feed mills were price sensitive.
The Central Question in Virology: The Origin and Evolution of Viruses
Authors: Awata Luka AO
Published: November 2021

Viruses are major threats to both animals and plants worldwide. A virus exists as a set of one or more nucleic acid molecules normally encased in a protective coat of protein or lipoprotein. It is able to replicate itself within suitable host cells, causing diseases to plants and animals. While the three domains of life trace their linages back to a single protein (the Last Universal Cellular Ancestor (LUCA), information on parental molecule from which all viruses descended is inadequate. Structural analyses of capsid proteins suggest that there is no universal viral protein and different types of virions are mostly formed independently. As a result, it is impossible to neither include viruses in the Tree of Life of LUCA nor to draw a universal tree of viruses analogous to the tree of life. Although the concepts on the origin and evolution of viruses are well documented, the structure and biological activities of viruses are paradoxical. This assay will provide a brief background on the discovery of viruses and highlight the universal hypotheses that have been adopted to explain the origin of viruses. The text will also look at the current views on the nature of viruses and how they evolved; and an attempt will be made to draw some assumptions towards understanding of how modern viruses originated. The views formulated would shed some lights on understanding of viruses and their evolution.
Soil Amendments with Sugarcane Bagasse and its Effect on Soil Humic Acid Contents and Chinese Cabbage Growth Components
Authors: Vegi Maheswara Rao
Published: November 2021

Sugarcane bagasse (SCB) which is a waste byproduct of sugarcane industry can be used as soil amendments to improve crop yield and provide reasonable economic means to recycle these wastes in an environment friendly manner. In this study experiments were conducted to test the rate of production of humic acid during the decomposition of SCB for 30 days and effect of SCB amendments on growth components of Chinese Cabbage (Brassica rapa, subsp. pekinensis). Humic acid were extracted using the classic alkali/acid fractionation method while FT-IR method was used to characterize humic acid. The results were shown that higher amount (0.2779g) of humic acid was extracted after 30 days, and small amount (0.0053g) was extracted from 0 day of SCB decomposition. The amount of humic acid extracted from SCB is significantly increased with respect to the time for decomposition of SCB. Growth performance of Chinese cabbage was recorded in terms of increase in plant height above ground, fresh and dry weight, root length, root fresh and dry weight. The experiment was conducted by 3 x 3 factorial designs employing three concentrations of SCB (0%, 2%, 5% and 10 %). The results showed that there is significant increase in plant growth components with increase of SCB concentration. It is recommended that application of SCB 10% will result in enhanced yield of Chinese cabbage. This may be due to high amount of humic acid produced by SCB after decomposition which leads to improve other soil characteristics.
Investigating the Effects of Self-Esteem on Attachment Styles in Individuals in Early Adulthood: The Mediating Roles of Emotional Dependency and Loneliness

Published: November 2021

Investigating the concepts affecting individuals' attachment styles in early adulthood is essential for healthy and satisfying social and emotional/romantic relationships. The purpose of this study was to examine the direct effects of self-esteem, loneliness, and emotional dependency on university students’ attachment styles. In addition, this study investigated the mediating roles of emotional dependency and loneliness on the relationships between attachment styles and self-esteem. The research group consisted of 518 volunteer university students in their first adulthood. Demographic Information Form, Rosenberg Self- Esteem Scale (RSES), Experiences in Close Relationships- Revised (ECR- R), Emotional Dependency, and UCLA Loneliness Scale were used to collect the data. Pearson moments correlation coefficients, hierarchical regression analyses, and bootstrapping methods were performed to test the hypotheses. The results of hierarchical regression analysis showed that self-esteem negatively and loneliness positively predicted anxious and avoidant attachment styles. Emotional dependency positively predicted anxious attachment and negatively predicted avoidant attachment styles. In addition, the bootstrapping analysis showed that loneliness played a significant partial mediator role on the relationships between self-esteem and avoidant and anxious attachment, while emotional dependency was not a significant mediator. The findings were discussed along with the theoretical basis and the previous findings, and suggestions were presented for future studies.
Which routes for optimal yield sampling in viticulture?

Published: November 2021

Estimating vineyard crop yield is important for preparing harvesting operations and vatting. Estimations are generally carried out by sampling shortly before harvest and observations are made on a limited number of sampling sites. The sampling process has obvious practical constraints, such as the time allocated to the operation, which determines both the number of sites to be sampled and the route to reach them.
