A rare case of “coronary slow-flow phenomena” in an aviator: An approach to aeromedical disposition – A case report
Authors: Manu N , Tripathy NK , Divya N 
Published: October 2020

Introduction:
Coronary slow-flow phenomenon (CSFP) is a frequent angiographic finding with obscure pathophysiology. Although recognized for decades, the incidence of such a clinical entity is rare in aviation environment and poses unique aeromedical challenges in disposition of the aircrew.

Case Details:
A 53-year-old asymptomatic pilot from a helicopter stream was detected to have ECG abnormality during a routine medical examination. His treadmill test was borderline positive for inducible myocardial ischemia, whereas angiography revealed proximal ectasia with a slow flow. He was diagnosed as a case of “Coronary Slow-Flow Phenomenon,” started on antiplatelets and was observed on ground for 36 weeks. A comprehensive cardiological evaluation following that revealed an asymptomatic status, controlled modifiable risk factors and no progression of ECG changes. Echocardiography, 24 h Holter, and stress MPI were essentially normal. Based on an evidence-based approach, the aircrew were reflighted back to flying in a multicrew aircraft.

Discussion:
This case study discusses our approach to aeromedical evaluation and disposition of a helicopter pilot with CSFP, which is unique, yet rarely encountered disability among aircrew.
Describing the continuum from ALOC to G-LOC
Authors: Kumar A , Nataraja MS 
Published: October 2020

Introduction:
G-induced loss of consciousness (G-LOC) has been extensively investigated and pathophysiology of the same has been well elucidated in the literature. The syndrome of almost loss of consciousness or ALOC has also been described which is a loose collection of signs and symptoms of a physiological, emotional, and cognitive nature. This is believed to occur under +Gz stress which is insufficient to cause G-LOC. Institute of Aerospace Medicine IAF regularly conducts high-G training for its fighter pilots in the High Performance Human Centrifuge. Episodes of G-LOC and ALOC are unintended outcomes of such training. A study was conducted to understand the nature of these episodes in the Department of Acceleration Physiology and Spatial Orientation.

Material and Methods:
A G-LOC/ALOC proforma was designed in the Department of Acceleration Physiology and Spatial Orientation to understand the nature and causes of the G-LOC/ALOC and was filled up by the aircrew on a voluntary basis. The data were analyzed using Microsoft Excel and SPSS 20 with significance set at 95% confidence interval and alpha at 0.05.

Results:
Forty-seven aircrew experiencing G-LOC/ALOC agreed to be part of the study and filled up the proforma after the episodes. However, only 42 proforma (31 G-LOC and 11 ALOC) was found suitable for the analysis. There was no statistical difference in heart rate (HR) measured during the rate of onset and G-level at which G-LOC and ALOC resulted. There was no difference in psycho-somatic manifestations of G-LOC and ALOC episodes.

Conclusion:
ALOC and G-LOC have similar manifestations and operational implications. There is ample evidence to suggest that ALOC is a manifestation of G-LOC syndrome rather than a separate entity.
An appraisal of happiness in civil aircrew
Authors: Narayanappa Divya , Sowgandhi Ch N , Tripathy NK , Agarwal A 
Published: October 2020

Introduction:
Commercial aviation is a unique occupation, where the professional responsibility to ensure the safety of the aircraft and its occupants lies with the pilot, making civil aviation a stressful and demanding job. Psychological fitness plays a crucial role in helping aircrew adapt to and deal with these occupational demands. In the past few years, the awareness and interest in mental health among civil aviators and the aviation industry have been on the rise. Happiness is characterized as a lasting state with positive emotions and life satisfaction. It is known to improve performance and reduce stress. Based on this, the main objective of this study was to conduct a survey to appreciate the level of happiness among civil aircrew.

Material and Methods:
A widely used scale for assessment of happiness called Oxford Happiness Questionnaire (OHQ) was administered to both male and female civil aircrew (n = 100). OHQ is a 29-item self-reporting questionnaire. Internal consistency was calculated using Cronbach’s alpha which was found to be 0.97 on the current sample. Data collected were also studied to find a correlation between demographic variables and happiness index.

Results:
A mean score of 4.87 was obtained in the OHQ which indicated that the civil aircrew perceived themselves to be quite happy. No significant relationship was found between age, experience, marital status, and happiness scores.

Conclusion:
This was a unique survey in which civil pilots flying both domestic and international flights from India were assessed in terms of their happiness level as a measure of psychological well-being. The participants consisted of a total of 100 aircrew, consisting of 87 males and 13 females. The happiness index in this sample was found to be moderate to high. Most of them perceived their lives and work to be meaningful, which led to high motivation and increased performance. The results also revealed that flying hours of civil aircrew had no significant relationship to happiness level, further indicating that age and experience of the pilots did not predict their happiness, which was akin to a number of researches conducted on the general population. Although the aircrew were found to be moderately happy, the happiness level could still be increased. Small and modest actions by both the aircrew and the airline industry may make a big difference to the happiness state of aircrew.

Проведен фитохимический анализ цветков, плодов и листьев по содержанию биологически активных веществ на двух видах клена: инвазионном Acer negundo L. и аборигенном A. platanoides L. (Sapindaceae Juss). У 40 образцов, собранных в 5 популяциях Московского региона, найдены сумма флавоноидов, содержание аскорбиновой кислоты и суммы органических кислот по стандартным методикам Государственной фармакопеи РФ. В данном исследовании впервые обнаружено, что максимальное накопление флавоноидов (1,75-1,94 мг%) фиксируется в мужских цветках A. negundo. Содержание витамина С в цветках (до 53 мг%), плодах и листьях A. negundo на 25-30 % больше, чем в аналогичных органах у A. platanoides. По мере созревания плодов содержание флавоноидов, аскорбиновой кислоты и органических кислот (до 8 %) у инвазионного и аборигенного видов клена снижается почти в 1,5 раза. Листья мужских и женских особей A. negundo по насыщенности флавоноидами, витамином С и органическими кислотами не отличаются. Выявлено, что цветки A. negundo и A. platanoides, являются наиболее перспективным источником биологически активных веществ - флавоноидов, включая катехины, антоцианы, лейкоантоцианы и флавонолы, а также аскорбиновой кислоты. Сбор растительного сырья рекомендуется проводить в экологически чистых фитоценозах, поскольку известно о способности растений A. negundo аккумулировать из почвы и воздуха тяжелые металлы.
A phytochemical analysis of flowers, fruits, and leaves revealing the biologically active substances in two types of maple: invasive Acer negundo L. and native A. platanoides L. (Sapindaceae Juss) was carried out. In 40 samples collected in 5 populations of the Moscow Region, a sum of flavonoids, the presence of ascorbic acid, and organic acids were found according to the standard methods of the State Pharmacopoeia of the Russian Federation. We discovered for the first time that the maximum accumulation of flavonoids (1.75-1.94 mg%) is in male flowers of A. negundo. The content of vitamin C in flowers (up to 53 mg%), fruits, and leaves of A. negundo is 25-30% higher than in similar organs in A. platanoides. As the fruit ripens, the content of flavonoids, vitamin C, and organic acids (up to 8%) in invasive and native species of maple decreases by almost 1.5 times. The leaves of male and female trees of A. negundo do not differ in saturation with flavonoids, vitamin C, and organic acids. Flowers of A. negundo and A. platanoides are the most promising source of biologically active substances - flavonoids, including catechins, anthocyanins, leukoanthocyanins, and flavonols, as well as ascorbic acid. The collection of plant substances is recommended in ecologically clean phytocenoses since A. negundo can accumulate heavy metals from soil and air.

Published: November 2020

Hydrocarbon contamination cause serious environmental damage and human health problems, therefore, to resolve this problem has been proposed diversely remediation techniques friendly with the environment i.e. bioaugmentation, biostimulation, natural attenuation and phytoremediation. Among options, the phytoremediation causes minimum alterations to soil, low cost, it has proved good eff iciency and gained public acceptation. In the present study, the capacity of Mimosa pigra to restore a contaminated soil with both anthracene and phenanthrene was evaluated, along with the soil physicochemical changes due to both plant and contaminant presence in the soil. A silt-loam contaminated soil with 100 mg kg-1 (dry weight) anthracene and 200 mg kg-1 (dry weight) phenanthrene was used in all three treatments: Contaminated soil with M. pigra (C1), contaminated soil without M. pigra (C2), and not contaminated soil with M. pigra (C0) as control. After 70 days of experimentation both biomass and height of M. pigra was not affected due to soil contaminants. There was no difference among treatments for some physicochemical characteristics e.g. soil pH, electrolytic conductivity, soil-texture, and total nitrogen content throughout the experiment. M. pigra increased the soil water holding capacity after 50 and 70 days of the experiment, however, total organic carbon content was lower after 70 days compared to the control treatment. The higher contaminant removal rate was before 7 days of experimentation for all treatments. Anthracene and phenanthrene content were lower in treatments with the presence of M. pigra: 92% of phenanthrene and 80% of anthracene were removed in C1 while nearly 77% of phenanthrene and 60% of anthracene were removed in C2. This suggest a greater removal of contaminants using M. pigra. Total removal of contaminants was not achieved. However, M. pigra was able to accumulate both compounds, showing the M. pigra capability for bioremediation use in contaminated soils.

A fracture model in rats for the study of secondary bone healing was described. Standard open midshaft transverse metatarsal fracture was produced with bone cutting forceps in 28 rats. The commonly open and close fracture models utilized for bone and mineral researches are associated with varying degree of complications ranging from a high degree of fracture comminution to severe associated soft tissue injury which interferes with the healing process. We hypothesized that fracture model in rat third metatarsal bone could be associated with low -post-surgical complications and could be a reproducible model. To test this, open mid-shaft transverse fractures were created on the metatarsals of 28 rats. The objectives of the study were to evaluate the fracture complications, to determine the nature of fracture produced, evaluate the fracture consolidation during healing periods, and to assess the histological and radiographic healing of the fracture. The fracture produced in the mid metatarsal shaft of all rats was 100% transverse, 73% located at the midshaft. Minimal fracture angulations were recorded (0.48 ± 0.09o; 0.78 ± 0.17o) for anterior-posterior and lateral views respectively. Minimal soft tissue injury was recorded immediately post-surgery, but no infection and the delayed union was observed. Varying degrees of weight-bearing lameness was also recorded but seized at day six onward post-operative. Callus index observed was peaked at week 2 and 3 (2.02 ± 0.1, 1.99 ± 0.13) respectively but declined to 1.10 ± 0.04 at week 7 during the consolidation period. The fracture line disappeared completely at week 7. The histological and radiographic healing scores were (3.5 ± 0.13 and 3.75 ± 0.25) respectively (out of the maximum healing score of 4) at week 7 post-operative. There was a positive correlation between the histological and radiographic healing scores. The metatarsal fracture model is considered to be a suitable model for in vivo study of secondary fracture healing. Doi: 10.28991/SciMedJ-2020-0204-2 Full Text: PDF

Published: October 2020

In this work two crude oil samples were investigated to present the difference between biodegraded (Velebit) and non-degraded (Kikinda) oil. Two samples are from the Velebit oil–gas field and the Kikinda oil-gas field. These are two of the largest oil and gas deposits in the Serbian part of the Pannonian Basin. In the experimental part of this work, two samples of crude oil were separated by column chromatography. Saturated hydrocarbons were analyzed by gas chromatography-mass spectrometry instruments. Based on the abundance and distribution of biomarkers, it could be conclude that the distribution is typical of oil in both samples, with difference in the distribution of n-alkane. GC-MS chromatogram of n-alkanes and isoprenoids of saturated fraction isolated from Velebit crude oil show the distribution typical of oils altered by biodegradation.

Published: October 2020

As a key supporting equipment for the construction of LNG carriers, the installation platform undertakes the support and guarantee of LNG carrier tank internal construction. This paper takes the secondary shielding installation platform of A-type tank as the object of study, the study firstly considers the semi-rigidity of the nodes and the material nonlinearity based on finite element software, and then the residual structure is calculated using static nonlinear method after single truss, two trusses and three trusses are invalid simultaneously. The research results show that the truss with higher components importance coefficient has greater impact on the residual structure when the truss is invalid; After the 2 trusses of installation platform become invalid completely, the further progressive collapse will not occur; When A1-HJ, A2-HJ and A2-HJ are dismantled at the same time, it will lead to the local progressive damage, which can cause the collapse of large-scale structures. The research findings can support the design and use of the installation platform.
