Illuminance and Luminance Based Ratios in the Scope of Performance Testing of a Light Shelf-Reflective Louver System in a Library Reading Room
Authors: Öner Merve , Kazanasmaz Tuğçe
Published: November 2019

Uncontrolled daylight brings visual and thermal problems that may result in negative interactions with user comfort, productivity, well-being, and human health. Library spaces, in which reading, writing, and computer task activities are performed, need to be well designed in terms of daylight performance to enhance user satisfaction. The focus of this study is to make a performance test of a light shelfreflective louver system to improve the visual performance conditions of a library reading room. First, the instrumental monitoring of existing daylighting conditions was performed. Second, Relux model was prepared to evaluate luminance patterns and illuminance distribution. Third, a new light shelfreflective louver system was proposed based on the insufficiencies of the simulation results. The performance of the new system was found highly satisfactory based on the findings of enhanced luminance patterns and uniformity ratios especially at the points near the windows.
Light Desynchronosis and Health
Authors: Anisimov Vladimir N.
Published: November 2019

The review summarizes the modern knowledge of the impact of day-night, light-darkness rhythm disorders on the aging process and on the risk of development of the age-related conditions. Significant evidence has been obtained of that the constant artificial illumination and the daylight of the North has a stimulating effect on the occurrence and de-velopment of tumours in laboratory animals. It has been shown that long-term shift work, trans-meridian flights (jet-lag) and insomnia increase the risk of cardiovascular diseases, diabetes mellitus, and ma-lignancies in humans. Particular attention is given to the studies where the relationship between light intensity, light wavelength and its ability to suppress the synthesis of melatonin produced at night in the pineal gland, are investigated. It has been established that melatonin synthesis is most effectively suppressed with blue light sources of a wave-length from 446 to 477 nm. The use of exogenous melatonin prevents premature aging of the reproductive system and the body as a whole prevents the development of immunesuppression, metabolic syndrome and tumours caused by light pollution. An urgent task is to develop recommendations for optimizing the illumination of workplaces and res-idential premises, of cities and towns as a preven-tion measure for premature aging and age-related pathology, which, ultimately, will contribute to the long-term maintaining of performance and improv-ing the quality of life.
ACTN-3 Genotype, Body Composition, Fitness, and +Gz Tolerance in Senior Cadets
Authors: Shin Seunghwan , Jee Hyunseok
Published: November 2019

BACKGROUND: This study aimed to investigate the relationships among ACTN-3, body composition, fitness, and +Gz tolerance for senior cadet training development and their safe task performance.METHODS: The subjects were all senior cadets (N =
68) at the Korea Air Force Academy. All cadets are required to pass a physical fitness test (3-km running, sit-ups, push-ups) and body composition test on a semiannual basis. Isokinetic muscle function (strength and endurance), +Gz test (+6 Gz ⋅ 30 s−1),
and target gene (ACTN-3) were analyzed.RESULTS: The effects of body composition and physical fitness along with the relationship of the ACTN-3 genotype to the +6 Gz test results were determined. Consequently, no significant difference was found concerning
the effect of ACTN-3 on the +6 Gz test result, body composition, and physical fitness; however, body fat (%) and isokinetic muscle strength (peak torque right leg extension and left leg flexion) showed significance between the pass and failure groups in the +Gz
test.DISCUSSION: The cadets of the Korea Air Force Academy showed dominant fast genetic expression type based on their ACTN-3 genotype [RR and RX (N = 51, 75%) > XX (N = 17, 25%)]. Body fat (%) and isokinetic muscle strength (PT R EX, L FL) can be more effective
predictors in the +6 Gz test for cadet training. Another speculation is that more RR- and RX-type-oriented training can promote cadets’ Gz tolerance from the isokinetic factors such as high peak torque and low fatigue index.Shin S, Jee H. ACTN-3 genotype,
body composition, fitness, and +Gz tolerance in senior cadets. Aerosp Med Hum Perform. 2019; 90(12):1055–1060.
Navigating the Management of an F-16 Pilot Following Spontaneous Splenic Rupture
Authors: Tanael Michael , Saul Solomon
Published: November 2019

BACKGROUND: Little consensus exists on the best practices for post-acute care of patients who suffer splenic injury but retain functional splenic tissue. Moreover, no published guidance or case reports exist for managing pilots in this demographic, making the flight surgeon’s
task particularly difficulty as he/she attempts to apply the best available evidence for a patient population exposed to unique occupational hazards.CASE REPORT: We describe the case of an F-16 pilot who suffered a spontaneous splenic rupture due to infectious mononucleosis and
required splenic artery embolization for hemodynamic stabilization. Despite the salvage of a significant portion of his spleen, the pilot was managed as an asplenic patient due to concern that: 1) splenic artery embolization compromised the function of his spleen; and 2) his status as a military
aviator placed him at increased risk of infection due to frequent travel. He received appropriate vaccinations for an asplenic patient, fever precautions, and amoxicillin-clavulanic acid for immediate use if he developed fever. After discussion with the Aeromedical Consult Service, who felt
the aviator had minimal risk of a poor outcome, he was returned to flying status. Since returning to flying status he has logged over 15 h of flight time, routinely experiencing 8–9 +Gz without difficulty.DISCUSSION: This case provides a successful approach to the
management of pilots of high-performance aircraft who suffer splenic injury but retain functional splenic tissue, and provides precedent for safely returning these patients to flying status following recovery.Tanael M, Saul S. Navigating the management of an F-16 pilot following

Adiponectin, blood pressure
and hypertension - a narrative review
Authors: Ivkovic Vanja
Published: November 2019

Adipokines, cytokines
derived from adipose tissue, not only herald and confirm fat tissue as the
largest endocrine organ but are also associated with a number of pathological
states including obesity, insulin resistance and diabetes. There is a growing body
of research on the role of adipokines in blood pressure regulation and
development of hypertension. One of these adipokines, adiponectin, is
especially interesting, given that it has numerous beneficial effects which
include increasing insulin sensitivity and antiatherogenic and
anti-inflammatory effects. In recent years, there has been a number of studies
examining its possibly protective role in hypertension. In this narrative
review we summarize the evidence on the association of adiponectin and polymorphism
of the gene which encodes it with blood pressure levels and risk of
hypertension, which might provide ideas for future research of adiponectin as a
biomarker and potential therapeutic target in this condition.

Published: November 2019

Introduction: Various reports
suggest linkage of protein expression to HPV status in cervical carcinomas. The
aim of this study was to determine a possible association between HPV type,
protein expression and DNA content in both preinvasive (CIN III) and invasive
squamous cell carcinoma (SCC) of the cervix, as well as differences between the
studied groups in these parameters. Materials and methods:
Sections of formalin-fixed paraffin-embedded tumor tissue from 47 cases of CIN
III and 60 cases of invasive SCC of the cervix were subjected to HPV genotyping
using LiPA (Line immuno-probe assay) and Flow cytometry for DNA content
analysis. Also, immunohistochemical staining was performed. Obtained data were
analyzed in SPSS using the Chi square test.
Results: The major difference
(p=0.007) between CIN III and invasive SCC of the cervix was found in DNA
content - more aneuploid and tetraploid cases in invasive SCC of the cervix
compared to CIN III. Although we observed a similar distribution of studied
parameters in both groups, no statistically significant association was found
between these parameters, except for p53 and pRb (p=0.018).
Conclusion: The studied groups differ in DNA
content. A significant association between analyzed parameters was observed in
Invasive SCC of the cervix between p53 and pRb expression.

Published: November 2019

Requirement of oil and gas industry in increasing of rate of hydrocarbon extraction from deposits contributes to development of science-based methods of oil production increasing. Vibrowave impact to productive seam is related to such methods. This impact can be effectively carried out with hole seismic signal sources. In the work results of study of load-bearing element of hole electro-magnetic pulse source are represented. Objective of the work is the study of static and dynamic strains of casing pipe, determination of values of pressure pulses at modified load-bearing element during its work with electro-magnetic striking center. Values of static and dynamic strains of casing pipe under the action of thrust force are experimentally determined. The values are located in flexible zone and make 1mm at the static load and from 0.35 up to 0.6mm at the pulse load. As the results of tests of vibration source prototype, dependence of pulse pressure value at load-bearing element on voltage of striking center supply under the pressure of preliminary pumping 20MPa is obtained. Pulse amplitude raises proportionally voltage in the range from 14.2 MPa up to 19.7 MPa. Experiments with increasing of pumping pressure in the range from 20 MPa up to 27 MPa have shown that ratio of pulse value to pumping pressure linearly reduces when voltage of striking center supply is constant. Obtained results are scientific basic for designing of load-bearing elements destined for work at pulse impact transfer mode.

Aim and Objective: The objective of the study was to evaluate the anti-plaque efficacy of lemongrass oil mouthwash. It also assessed the antibacterial properties of lemon grass oil against Prevotella intermedia (Pi), Porphyromonas gingivalis (Pg), and Aggregatibacter actinomycetemcomitans (Aa) in vitro.

Materials and Methods: Forty-five periodontally healthy subjects between the age group of 18 and22 years were enrolled in a 4-day plaque re-growth study. Subjects were divided into three groups, i.e., 15 in each group. Mouthwashes were labelled as A (0.25% lemongrass oil mouthwash), B (0.2% Chlorhexidine mouthwash) and C (placebo). Subjects were advised to refrain from any kind of mechanical oral hygiene procedure for four days. Plaque index (PI) was evaluated at baseline and on the fifth day. In vitro testing of lemon grass oil mouthwash was done against strains of Prevotella intermedia, Porphyromonas gingivalis, and Aggregatibactor actinomycetemcomitans, to evaluate the antimicrobial concentration of lemon grass oil mouthwash.

Results: PI significantly increased from day 1 to day 5 (P < 0.05) in Groups A, B, and C. In inter-group comparison, there was a statistically significant difference between the three groups. However, chlorhexidine showed superior antiplaque activity. Lemon grass also demonstrated antiplaque activity, however, not as superior as chlorhexidine. In vitro test, lemon grass showed effective inhibition against all three bacterial strains Pi, Pg, and Aa at 0.01% concentration.

Conclusion: Lemongrass oil mouthwash potently inhibits plaque formation and hence can be used as a natural herbal alternative.

Authors: Narciso Pedro Felipe
Published: November 2019

O trabalho a seguir compõe a etapa exploratória de uma pesquisa ainda em andamento, cujo resultado deverá ser uma dissertação de mestrado acerca das disputas que envolveram o processo de discussão e aprovação da Lei nº 12.351, a qual estabeleceu o regime de partilha de produção para determinadas áreas do Pré-sal. O objetivo da referida etapa de pesquisa é o de oferecer uma avaliação crítica de diferentes arcabouços teóricos, confrontando-os no sentido de depurar seus pontos mais problemáticos, fundamentando, assim, a escolha de um instrumental teórico capaz de abarcar os processos de interação entre o político e o econômico. No que se refere aos procedimentos de pesquisa, realizou-se uma revisão bibliográfica de caráter focalizado, tendo como critério básico de busca o objetivo supracitado. Da referida revisão apreciou-se criticamente as seguintes composições teóricas: o elitismo clássico e posicional, o pluralismo e os marxismos de Ralph Miliband, Edward Thompson e Nicos Poulantzas. Dessa abordagem panorâmica sobre as diferentes possibilidades teóricas foi possível concluir que a teoria regional do político de Nicos Poulantzas é aquela que disponibiliza as ferramentas mais adequadas para a investigação da relação entre o político e o econômico.

O artigo é produto de um esforço de aproximação da noção de habitus para a compreensão de contextos e práticas situadas no âmbito da criminalidade urbana. Para além de ampla revisão bibliográfica, retomam-se no presente estudo dados de pesquisa etnográfica realizada entre os meses de abril e novembro de 2017 junto a vendedores, consumidores e usuários de drogas, em uma grota da cidade de Maceió (AL). O que se pretende com a mobilização das categorias, das falas e das observações selecionadas é propor uma categoria analítica aqui denominada como habitus criminoso. Acredita-se que esta categoria reserva potencialidade para contribuir com o debate e o entendimento de aspectos da formação da conduta criminosa e do ingresso nas carreiras da ilegalidade.

The purpose of the work is to develop methods for the treatment of oxidized quartzite, using methods of electochemical effects on hematite grains, converting it into magnetite for further magnetic separation. In laboratory conditions, the basic parameters of the process of recovery of hematite component of oxidized quartzite in aqueous suspension to magnetite with its magnetic properties have been established. When conducting the process of recovery of hematite to magnetite, the possibility of replacement of high-alkaline electrolytes with neutral salts formed by solutions has been established.The influence of structural features of experimental reactors on the recovery of hematite to magnetite has been developed and analyzed; the ability of membrane materials to effectively separate the anolytic and catholic spaces; the influence of electrode materials - anode and cathode, on the magnetization process; electrical parameters of electrical influence on the course of the process; composition of the electrolyte in the process of magnetization. The fiberglass membrane was shown to have a better ability to separate the anolytic and katholyte; maximum degrees of magnetization obtained when using electrodes from low carbon steels; optimal values of the degree of recovery of hematite in laboratory conditions were obtained at 15-25 V and 2.0-4.0 A. The thermodynamic possibility and realization of the processes of reduction of oxidized ores in aqueous solutions of electrolytes at low temperatures with obtaining the magnetic phase are shown. For electrolysis, high alkaline electrolytes can be replaced by electrolytes based on chloride and sulfate salts. The best results are obtained using NH4Cl ammonium chloride.

Antropojenik İklim Değişikliğine Bağlı Deniz Seviyesi Değişiminin Sinop Yarımadası’na Olası Etkileri
Authors: ÜSTÜN Yusuf Mert
Published: November 2019

Küresel iklim değişikliği; kuraklıklar, seller, fırtınalar
gibi bir dizi probleme yol açmaktadır. Öte yandan yükselen sıcaklıklar, Dünya
buzul varlığını derinden tehdit etmektedir. Eriyen buzullar, küresel deniz
seviyesini hızlı bir şekilde yükseltmekte olduğundan dolayı kıyıdaki alçak
alanlar doğrudan, kara içindeki yüksek alanlar ise dolaylı yoldan deniz
seviyesindeki yükselişten etkilenecektir. 
Çalışmada deniz seviyesi yükseliminin Anadolu’nun kuzey ucu olan Sinop
Yarımadası üzerindeki olası etkilerinin Coğrafi Bilgi Sistemleri kullanılarak saptanması
amaçlanmıştır. Bu amaçla Hükümetlerarası İklim Değişikliği Paneli (IPCC)
tarafından hazırlanmış 5. değerlendirme raporundaki tahminler ışığında, Dijital
Yükseklik Verileriyle birlikte üretilmiş topografya haritaları oluşturulmuş ve
risk altında kalabilecek alanlar tespit edilmiştir. Bu çalışmalar sonucunda
yarımadanın büyük bir bölümünde hâkim olan yüksek kıyıların, yükselecek deniz
seviyesinden doğrudan etkilenmeyeceği ancak Sarıkum Gölü ve çevresi gibi kimi
alçak alanların deniz tarafından işgal edilmesiyle, hassas ekosistemlerinin
tehdit altında kalacağı sonucuna ulaşılmıştır. Ayrıca Sinop şehir merkezinin iç
limana bakan kısımları başta olmak üzere, şehrin; tarihsel, ekonomik ve
sosyokültürel yapısının zarar görebileceği saptanmıştır. Her ne kadar uzun
dönemli bir problem olsa da günümüzde etkilerini yağış değişiklikleri
vasıtasıyla derinden hissetmeye başladığımız küresel iklim değişikliğine karşı,
hızlı şekilde etkili önlemler alınması gerekmektedir. Bu önlemler çerçevesinde
kıyıyı dizginlemeye çalışmak gibi masraflı ve tehlikeli, geçici çözümler yerine
temiz ve yenilenebilir enerji kaynaklarına önem verilmesi ve iklim
değişikliğine karşı kamuoyunda bilinç oluşturulması önerilmiştir.

Special Spatial Symmetry of Mineral Structures
Authors: Shablovsky Ya.О.
Published: November 2019

Formation of mineral structures is afected both by energetic and crystal chemical barriers: limitations of possible choice of positions of structural units in a crystal lattice caused by features of its Fedorov group. The correspondence of structures of thermodynamically instable mineral phases to priority (most likely) crystal chemical types provides for their kinetic stability. At the same time, crystallization of rare structure is possible only upon conditions of its energetic stability, because the rarity of the Fedorov group indicates its low «crystal chemical feasibility» of the corresponding structure. The phenomenon of rare Fedorov groups is stable, since it is caused by fundamental crystal chemical reasons. It is most striking in a framework structure of a crystal lattice, because the mineral phases can contain 24 various types of 3D-periodical framework structures. The minerals with framework structure can exhibit the efect of supersymmetry, i.e., stability of the structure with chemically identical but symmetrically independent structural units. This efect may be typical of framework structures corresponding to Fedorov groups P42m, P4m2, I42m, I4m2, P222, C222, F222, I222, P23, F23, I23, P432, P4232, F432, P422, I422, P4222, P6222 and P6422. In particular, this structural efect is typical of cubic modifcation of lazurite with Fedorov group P23.
