Authors: Noor Mohamad Noor Azura , Daud Suzanna , Thow Sun Ta , Singh Chopra Darminder , Abdullah Bahiyah , Abdullah Bahiyah
Published: December 2019

Heterotopic interstitial pregnancy in natural conception is very rare. Definitive diagnosis is made by systematic pelvic ultrasound. Simultaneous viable conception observed in both intra- and extra-uterine is pathognomonic of heterotopic interstitial pregnancy. We report a 34-year-old woman primigravida at 10 weeks’ amenorrhoea who underwent evacuation of retained product of conception for missed miscarriage. Intraoperatively, minimal product of conception was retrieved. Bedside pelvic ultrasound showed cystic mass at right superolateral part of uterine fundus suspicious of interstitial pregnancy. Cornual resection was performed via laparotomy. Histopathological examination showed presence of product of conception and interstitial pregnancy. Serum β-human chorionic gonadotropin dropped from 10,027 IU/l on day one post-ERPC to 210 IU/l at day three post-cornual resection. This case report highlighted the challenge in diagnosing heterotopic interstitial pregnancy conceived naturally. Timely diagnosis may avert dire consequences of massive haemorrhage from ruptured uterine cornua.

Authors: Kassim Zawiah , Ahmad Fauziah , Mustapha Kamar Rusnaini , Misiran Karis
Published: December 2019

Safety and feasibility of transoral robotic surgery (TORS) in adults for otolaryngology surgery, mainly in the treatment of oropharyngeal carcinoma and obstructive sleep apnoea has already been established several years ago. However, less is known with respect to the role and safety of TORS for otolaryngology surgery in the paediatric age group and its description in the literature is currently insufficient. As paediatric patients are unique in their anatomy, physiology and pharmacological kinetic, special attention and consideration has to be applied when using TORS, hence this increases the perioperative challenges. Herewith we present our experience in anaesthetising a paediatric patient for TORS adenotonsillectomy which is the first not only in our centre but in Malaysia. Our major obstacle was the limited airway access as the area of concern was shared by the anaesthesiologist, surgeon and also the robotic system. Haemodynamic stabilisation was a challenge compared to the conventional method as the operative time increased due to robot docking time and the new surgical learning process. In our opinion, the key point for the success of TORS adenotonsillectomy in paediatric patients is good communication and team work between all personnel involved in the surgery.

Authors: Ivashko Larysa
Published: December 2019

The task of the competence-based approach in higher vocational education is the training of qualified specialists that are competitive in the labour market. The review of the requirements of numerous firms to the competence of employees showed that for a particular business one needs professionals who have certain "business"-competencies that bring profit to the company: no profit – specialist has no competencies. At the same time, more attention is paid to universal competencies when hiring. As a rule, professional competence is confirmed by the diploma of the university. In work methodical features of various approaches to modelling "business"-competencies at employment of graduates of high schools are considered.
Keywords: professional concepts, universal competencies, "business"-competencies, indicators (concepts), modelling "business"-competencies.

Más allá de nativos e inmigrantes
Authors: Benítez Larghi Sebastián , Ugarte Daniela
Published: December 2019

El objetivo del trabajo es comprender los modos en que la apropiación de Internet varía a lo largo del curso de vida mediante la comparación de las trayectorias de personas jóvenes, adultas y adultas mayores en dos conglomerados urbanos de Sudamérica (Lima Metropolitana, Perú, y el Área Metropolitana de Buenos Aires (AMBA), Argentina). Para ello se analizan los datos recabados mediante una investigación de corte cualitativo basada en la realización de entrevistas en profundidad a sujetos de diferentes grupos de edad, nivel socioeconómico y género en ambos conglomerados. Como hallazgo principal se identifica que la edad por sí sola no define trayectorias de apropiación de Internet diferenciadas sino que ello depende también de los contextos de socialización, la acumulación de determinados capitales y la biografía personal. Así, al interior de un mismo grupo etario se vislumbran rasgos claramente generacionales pero, al mismo tiempo, se detectan matices intra-generacionales asociados a trayectorias de sociabilidad, educativas y laborales previas. En las conclusiones, se establecen vínculos entre desigualdades sociales y la apropiación de Internet en el marco de procesos de transformación social más amplios.
Entre un chico adicto al trabajo y sólo estaba haciendo mi trabajo
Authors: Bermúdez Natalia Verónica , Caminos Berton Fernanda
Published: December 2019

El presente artículo analiza etnográficamente los modos en los que el “trabajo” se constituye como dispositivo legitimador de reputaciones individuales y de prácticas de distintos actores involucrados en una muerte por violencia policial. Hemos observado que en estas muertes la denuncia pública, lejos de inscribirse en la retórica de los derechos humanos, se individualiza a través de complejos procesos de moralización para defender las vidas de los jóvenes muertos en contextos de violencia en sectores populares de Córdoba. 
Proponemos entonces reflexionar sobre los procesos de demarcación y diferenciación que realizan las y los allegados al muerto –específicamente familiares- para constituirlo públicamente como “buena víctima”, a través de sostener su pertenencia a una familia trabajadora y de relacionar su trabajo con el sacrificio en pos de desvincularlo de prejuicios que recaen sobre él por su pertenencia de clase. 
Por otra parte, se analiza cómo el trabajo se constituye en dispositivo legitimador de prácticas policiales cuando es utilizado como argumento para justificar la violencia física ejercida en pos de combatir la ilegalidad. Así, se problematiza el trabajo de policía para pensar cómo son los modos considerados legítimos de la actuación policial y qué subjetividades dan sentido a estas prácticas.

Effect of 3% chloroprocaine hydrochloride when used for median and ulnar regional nerve blocks in lame horses
Authors: Boone Lindsey H. , DeGraves Fred J. , Klein Chelsea E. , Cole Robert C. , Schumacher John
Published: December 2019

OBJECTIVE

To assess onset of analgesia for 3% chloroprocaine hydrochloride and 2% mepivacaine hydrochloride when used for median and ulnar nerve blocks in lame horses.

ANIMALS

6 naturally lame horses.

PROCEDURES

A crossover experiment was conducted. Horses were assigned to 1 of 2 treatment groups (3% chloroprocaine or 2% mepivacaine first). Median and ulnar nerve blocks were performed in the lame limb with the assigned treatment. Lameness was objectively evaluated before treatment administration and at various points for 120 minutes after treatment with a wireless inertial sensor-based motion analysis system. Following a 7-day washout period, horses then received the other treatment and lameness evaluations were repeated.

RESULTS

Median and ulnar nerve blocks performed with 3% chloroprocaine resulted in more consistent, rapid, and profound amelioration of lameness than did blocks performed with 2% mepivacaine. Lameness decreased more between 20 and 40 minutes after injection when 3% chloroprocaine was used than when 2% mepivacaine was used. Complete resolution of lameness was detected a mean of 9 minutes after injection when median and ulnar nerve blocks were performed with 3% chloroprocaine and a mean of 28 minutes after injection when performed with 2% mepivacaine.

CONCLUSIONS AND CLINICAL RELEVANCE

3% chloroprocaine had a more rapid onset and provided better analgesia for median and ulnar nerve blocks in horses with naturally occurring lameness, compared with 2% mepivacaine. These favorable properties suggest that 3% chloroprocaine would be useful for performance of median and ulnar regional nerve blocks during complicated lameness evaluations.
Effects of intra-abdominal pressure on laparoscopic working space in domestic rabbits (Oryctolagus cuniculus)
Authors: Kabakchiev Claudia M. , zur Linden Alex R. , Singh Ameet , Beaufrère Hugues H.
Published: December 2019

OBJECTIVE

To assess the effects of 3 intra-abdominal pressures (IAPs) on pneumoperitoneal (laparoscopic working space) volume in domestic rabbits (Oryctolagus cuniculus).

ANIMALS

6 female New Zealand White rabbits.

PROCEDURES

A Latin-square design was used to randomly allocate sequences of 3 IAPs (4, 8, and 12 mm Hg) to each rabbit in a crossover study. Rabbits were anesthetized, subumbilical cannulae were placed, and CT scans were performed to obtain baseline measurements. Each IAP was achieved with CO2 insufflation and maintained for ≥ 15 minutes; CT scans were performed with rabbits in dorsal, left lateral oblique, and right lateral oblique recumbency. The abdomen was desufflated for 5 minutes between treatments (the 3 IAPs). Pneumoperitoneal volumes were calculated from CT measurements with 3-D medical imaging software. Mixed linear regression models evaluated effects of IAP, rabbit position, and treatment order on working space volume.

RESULTS

Mean working space volume at an IAP of 8 mm Hg was significantly greater (a 19% increase) than that at 4 mm Hg, and was significantly greater (a 6.9% increase) at 12 mm Hg than that at 8 mm Hg. Treatment order, but not rabbit position, also had a significant effect on working space. Minor adverse effects reported in other species were observed in some rabbits.

CONCLUSIONS AND CLINICAL RELEVANCE

A nonlinear increase in abdominal working space was observed with increasing IAP. Depending on the type of procedure and visual access requirements, IAPs > 8 mm Hg may not provide a clinically important benefit for laparoscopy in rabbits.
Warrior and peacekeeper role identities: associations with self-esteem, organizational commitment and organizational citizenship behavior
Authors: Buijs Tessa op den , Broesder Wendy , Goldenberg Irina , Resteigne Delphine , Kivirähk Juhan
Published: December 2019

This article focuses on military role identity by assessing the relations between demographic variables and warrior and peacekeeper role identities and by examining the potential influence of these role identities on self-esteem, organizational commitment and organizational citizenship behavior (OCB) in a cross-national sample. A questionnaire was distributed to military members in four participating countries: Belgium, Estonia, Canada and the Netherlands (n = 831). The findings show that demographic variables (i.e., age, gender, marital status and unit) are related to military role identity, and that military role identity predicts self-esteem, organizational commitment and OCB. In particular, multiple regression analyses demonstrate that peacekeeper role identity predicts self-esteem, organizational commitment and OCB, whereas warrior role identity only predicts organizational commitment and OCB, and further, that peacekeeper role identity is a stronger predictor of the outcome variables measured. The theoretical and practical implications, including providing commanders with information to assess their units’ mindsets, and mechanisms to improve self-esteem, commitment, OCB, are discussed. Finally, the limitations of this study and its potential for future research are described.

Published: December 2019

Este estudio investiga la incertidumbre asociada con el modelo de circulación general (MCG) al escenario de emisión y a la variabilidad natural del clima en la estimación del impacto del cambio climático en dos cuencas mexicanas. Las cuencas seleccionadas tienen diferentes climas y regímenes hidrológicos. Las simulaciones climáticas de tres MCG bajo tres escenarios de emisión (B1, A1B y A2) se usan para alimentar el modelo hidrológico SWAT, de tipo físico y semidistribuido. Las simulaciones cubren 30 años en un periodo de referencia (1971-2000) y dos periodos de 20 años en el futuro (2046-2065 y 2081-2100). Los resultados muestran que los caudales altos son más propensos a ser influenciados por la incertidumbre asociada con el MCG; además, los indicadores hidrológicos tienen una sensibilidad menor al escenario de emisión para las cuencas de estudio. Por último, la incertidumbre vinculada con la variabilidad natural no debe pasarse por alto en los estudios de cambio climático, ya que hasta cierto punto y para caudales altos puede ser tan crítica como la incertidumbre ligada con MCG y el escenario de emisión.

Experimental Study on the Effect of Marine Engine Lubricant Degradation on Tribological Performance of Cylinder Liner and Piston Rings Contact Using a Tuning Fork Technology Based Oil Sensor
Authors: Anand M , Hadfield M , Viesca JL , Thomas B
Published: December 2019

An investigation was carried out to study the effect of changes in oil quality on its tribological performance using a tuning fork technology based oil sensor. In this research, a tribological testing system was commissioned, to simulate the piston ring-cylinder liner sliding contact, and to measure the lubricant condition in real-time using an oil sensor. Tribological contact between cylinder liners and piston rings in marine engines is the most affected region due to excessive thermo-mechanical stresses. At top dead centre, the effect of such stresses is at a maximum where piston-sliding speed is lowest, while the temperature is high due to fuel combustion, and radial load behind the piston rings compressing against the cylinder liner surface is at a maximum due to gas pressure and the compression fit of piston rings within the cylinder liner. At bottom dead centre, this effect is less severe due to a reduction in temperature and gas pressure on the piston rings, as the piston is positioned away from the combustion chamber. These two regions experience boundary lubrication conditions, where anti-wear and anti-friction additives are responsible for forming a protective lubricious film on sliding surfaces. At mid-stroke, piston-sliding speed is maximum, therefore, a full hydrodynamic film is formed in this region separating the piston rings and cylinder liner. The formation of oil film depends upon, the physical properties of oil (such as viscosity and density) under hydrodynamic lubrication conditions, and the oil chemistry (such as presence of additives in oil) under mixed or boundary lubrication conditions. Lubricants in marine engines undergo intense degradation in quality due to contamination with wear particles, water, soot, un-burnt fuel, coolant, and additives depletion. Such degradation of lubricants leads to a reduction in their capability to form a minimum thickness of oil film between two moving engine components to avoid direct metal-to-metal contact, which may cause wear. Therefore, monitoring the condition of marine engine lubricants is vital in order to predict any significant change in its quality. The results obtained from tribology testing and oil condition monitoring in the current research showed a good correlation and are useful to understand the performance of lubricants for piston ring-liner contacts.
Hydro-elastic analysis of carbon composite marine propeller using co-simulation technique
Authors: Kumar A , Subramanian V A , Vijayakumar R
Published: December 2019

Carbon fibre composite has extremely high strength, low density and no corrosion in sea water. These characteristics make it a favourable alternative for consideration as material for marine screw propellers. The obvious advantages are lightweight propeller, resistance to corrosion, and possibly favourable fatigue characteristics. As against this, the relatively higher flexibility of material needs investigation since change of geometry due to load on the blades can affect the hydrodynamic performance. These materials are reduced stiffness and anisotropic in nature, and therefore hydro-elastic based performance analysis is required to understand their performance in operating condition. The current study focuses on numerical investigation for the hydro-elastic based performance analysis of a composite marine propeller in open water condition. The procedure involves the coupling of  Reynolds-Averaged Navier-Stokes Equation (RANSE) based Computational Fluid Dynamics (CFD) solver with the Finite Element Method (FEM) solver using Co-Simulation technique. The open water characteristics including thrust coefficient (KT), torque coefficient (KQ), and open water efficiency (ηo ) analyzed as a function of the advance ratio (J). This paper presents a comparison of the hydrodynamic performance between the composite propeller and a conventional steel propeller taking into account the structural response under loading. The results for the composite propeller show improved thrust value in comparison with the conventional metallic propeller.

Published: December 2019

This report showed a case study of a mini-cape size bulk carrier of being retrofitted for Liquefied Natural Gas (LNG) fuel and the selection of its new fuel tanks to meet the stringent emissions requirement. The vessel was equipped with a dual fuel ready (DFR) engine before the retrofit. Engine manufacturer will supply and replace engine parts for LNG fueled operations with no significant modification of the engine structure required. The detailed engineering design considerations were studied with cost reduction and minimum downtime set as ultimate objectives. Top-down and bottom-up approaches for cost estimation are used in this analysis. The analysis was determined by life cycle cost and management costs. The cost analysis showed the payback period of an LNG fueled ship retrofit is 4.5 years against a 0.5%S compliant fueled vessel. The payback period is considered reasonable and it shows retrofitting vessels for LNG fuel as an attractive option in meeting new regulation for ship-owners. If the shipyard standardizes the tank construction including outfitting, the specified cost may even go lower. A further reduction is also anticipated with repeating orders of similar vessels.

Transfer of modern technology (ToMT) including upgrading/alterations/additions (As and As)) through individuals’ organizational effectiveness of training (EoT) in the Omani ships’ repairs environment (OSRE) remains a challenging issue, particularly with regards to the future of on-going projects such as ships/maritime materiel, infrastructure and platforms that continue their operations for many years after acceptance dates. ToMT/upgrading is done to enhance the capability of the whole dockyard/navy through a predetermined arrangement, involving many areas of interest such as the knowledge, competencies and skills (KCS) of the indigenous workforce to support the capability. Typical examples that can drag/slow down the modern KCS development of the indigenous workforce are to fully depend on the outside contracts, manpower substitution, external organization and institutions to do the work, which can also be expensive in the short and long-term. Technology transfer requires a high level of commitment and expertise from both the technology provider and the recipients/owner/indigenous workforce. Intellectual talents are a decisive requirement, followed by financial resources, particularly when major contractual projects and long-term relations are involved. This literature review and methodical study endeavoured to draw previous experience of the organizations under study, including the Omani Dockyard, to understand the current situational readiness of knowledge, competencies and skills (KCS) in single- and double-loop learning. The KCS are valued by emphasising the need for force for direction, force for efficiency, force for proficiency, force for innovation, force for concentration and force of cooperation as ‘a system of forces’ and also the effectiveness of training, to deliver overall Organizational Performance. The study begins by significantly and initially forming a model to introduce the determinants for the subject of study, followed by a critical literature review on ToMT and the determinants of the model. The discussion and conclusions are intended to outline the method that enhances readiness for new technology. The main contributing factors are the know-how to develop expertise and transfer KCS in the workplace. This study has determined the collaborative value of the current business to see whether future acceptance of new knowledge or technology transfer can be entertained.

Aim of the study. To study the effect of therapy with prophylactic and supraphysiological doses of cholecalciferol on skin microcirculation (MC) indicators in patients with type 2 diabetes mellitus with diabetic peripheral neuropathy (T2DM with DPN).

Material and methods. The study included 62 participants with T2DM with DPN (according to the Neuropathy Disability Score (NDS) scale, more than 4 points). By the method of consecutive numbers, patients were randomized into two groups: Group I (n=31, 15 men/16 women, 52.4±5.7 years) and Group II (n=31, 16 men/15 women, 51.4±6.1 years). Antihyperglycemic treatment was stable during the study. For 24 weeks, cholecalciferol participants from Group I received once a week at a dose of 5,000 IU, and from Group II - once a week at a dose of 40,000 IU. Body mass index (BMI), serum levels of 25(OH)D (25-hydroxycalciferol) and serum glycated hemoglobin (HbA1c) were evaluated before and after 24 weeks of taking cholecalciferol. The method of laser Doppler flowmetry (LDF) compared the initial and final indicators of the baseline level of blood flow and microcirculation indicators against the background of functional tests (postural and occlusive). Control measurements of LDF parameters were performed on 16 subjects without revealed diabetes mellitus (8 men/8 women, 51.8±3.7 years).

Results. Patients from Group II, after 24 weeks of taking supraphysiological doses of cholecalciferol, against the background of 100% normalization of the serum 25(OH)D level, significantly improved the parameters of skin MC and functional tests, HbA1c and BMI decreased.

Conclusions. Acceptance of high doses of cholecalciferol for 24 weeks has been associated with an improvement in the parameters of glycaemia and indicators of cutaneous MC in patients with T2DM with DPN.
Specificity of manifestation of functional asymmetry microcirculation parameters at physical loads on the upper limbs
Authors: Mezentseva L. V.
Published: December 2019

Purpose – the study the functional asymmetry of oscillatory processes of microcirculatory bed at physical loads on the upper limbs.

Material and methods. Microcirculation parameters were measured in 5 healthy volunteers (men aged 50–55 years) by laser Doppler flowmetry (LDF). LDF signal sensors were fixed symmetrically on the lower parts of the right and left shoulders (3 cm above the elbow bend). Physical exercise consisted of machs left or right hand in the standing position for 1 min. Measurements were performed in 3 conditions: 1 – initial state, 2 – immediately after exercise, 3 – 5 min after load termination The changes in the mean perfusion value and the components of the amplitude-frequency spectrum of blood flow fluctuations (myogenic, neurogenic, respiratory and cardiac), as well as the correlation between the changes in all parameters of the right and left sides of the observation were evaluated.

Results. Asymmetry of changes in microcirculation parameters and correlations between them under the physical loads on the upper limbs was revealed. It is shown that both left and right machs change the microcirculation parameters of both the left and right sides, and the changes on the left are more pronounced than on the right. It is shown that after the left machs the blood flow on the left and right increases, and after the right machs – reduced. After loads the right side is recovering more slowly than the left.

Conclusions. Our results illustrate the specific regulation of blood flow in micro vessels of paired organs, which is associated with functional asymmetry. The physiological mechanisms for this asymmetry require further experimental and clinical studies.
About interrelation of intracranial pressure and cerebral blood flow when positioning at patients with acute brain damage

Changing of «head – of – the bed» position is a routine method of positioning the patient to correct intracranial hypertension. In intensive care units, the «head – of – the bed» position vary from 0 to 60 °, and there is no consensus on which of them is most effective. The review of the major publications in the domestic and foreign literature about the problem of interrelation between positioning and changes of intracranial pressure, system and cerebral hemodynamic in patients with brain damage including databases eLibrary, PubMed, with the key words «hyperthermia», « positioning», «slope angle of the head of bed», «intracranial pressure», «cerebral perfusion pressure», «cerebral blood flow», «brain damage», and their combination. It is believed that the majority of patients with cerebral damage, regardless of the etiological factor, is preferable to 15–30° «head – of – the bed» position. In some cases manipulation of the head of the bed can lead to irreversible ischemic damage, due to the reduction of system and perfusion pressure, and cerebral blood flow. Thus, the selection of the optimal body position in acute cerebral pathology remains a debated issue. In this way, individual tactics of positioning in patients with cerebral damage allows choosing the correct intensive care and improving the treatment results.
