On the Areospace-Grade Adhesives Shear Strength Testing with ASTM D5656 Test as an Example
Authors: Karny Maciej 
Published: July 2019

Abstract
This article presents adhesive shearing test methods, focusing especially on the ASTM D5656 method. These methods will be briefly characterized and compared. The most important concerns about the D5656 method are described. With the use of ASTM D1002 and D5656 methods, the influence of adherend surface preparation on shearing properties of the bond is evaluated. Compared to sandblasting only, sandblasting followed by the FPL process (sulfochromate etching of aluminum) increased shear strength of joints by 35 % for ASTM D1002 tests and by 48% for D5656 tests. Comparing these two methods, shear strength obtained in D5656 tests is about two times higher than in D1002 tests. The cause for this phenomena is much larger adherend thickness in the D5656 method, which provides the coupons with increased stiffness. Shear modulus, calculated with 3 different calculation methods, showed differences in obtained results, which points to necessary actualization of D5656 standard.
Numerical Study of an Isothermal Slush Flow for Aerospace Propulsion Applications
Authors: Di Battista Ruben , Teresa Scelzo Maria , Rosaria Vetrano Maria 
Published: July 2019

Abstract
Slushes are two-phase solid-liquid single-species cryogenic fluids that exhibit an increased density and a greater heat capacity with respect to the corresponding normal boiling point liquids. These promising features are of large interest for applications that exploit slush as a thermal fluid, like super magnets refrigeration, cryogenic cooling of bio-materials or air conditioning, and for aerospace systems that use slush fluids as fuel or oxidizer. Several programs in the frame of the research on Slush Hydrogen (SLH2) as a new-generation fuel for aerospace propulsion have been started in the past. This work was carried out in the framework of a VKI research activity promoted by the Predict ESA Technology Research Programme, to investigate experimentally and numerically the behavior of slush flows in a representative upper stage feeding line. In this paper, we present a simulation based on a granular two-fluid model on an isothermal solid liquid mixture (slurry) and a Nitrogen slush (SLN2) fluid flowing in a horizontal pipe. A finite-volumes discretization using the software library OpenFOAM was benchmarked against experimental and numerical literature data, to assess the accuracy of the code in predicting pressure drops along the pipe axis and solid particle distribution across the pipe diameter. Moreover, the effects of concentration and inlet velocity are investigated. We show that the numerical model fairly reproduces the literature data in terms of important aspects as the solid volume fraction distribution and the pressure drops, especially for high flow rates.
Hybrid-Optional Effectiveness Functions Entropy Conditional Extremization Doctrine Contributions into Engineering Systems Reliability Assessments
Authors: Andriy Viktorovich Goncharenko 
Published: July 2019

Abstract
In this publication a Doctrine for the Conditional Extremization of the Hybrid-Optional Effectiveness Functions Entropy is discussed as a tool for the Reliability Assessments of Engineering Systems. Traditionally, most of the problems having been dealt with in this area relate with the probabilistic problem settings. Regularly, the optimal solutions are obtained through the probability extremizations. It is shown a possibility of the optimal solutions “derivation”, with the help of a model implementing a variational principle which takes into account objectively existing parameters and components of the Markovian process. The presence of an extremum of the objective state probability is observed and determined on the basis of the proposed Doctrine with taking into account the measure of uncertainty of the hybrid-optional effectiveness functions in the view of their entropy. Such approach resembles the well known Jaynes’ Entropy Maximum Principle from theoretical statistical physics adopted in subjective analysis of active systems as the subjective entropy maximum principle postulating the subjective entropy conditional optimization. The developed herewith Doctrine implies objective characteristics of the process rather than subjective individual’s preferences or choices, as well as the states probabilities maximums are being found without solving a system of ordinary linear differential equations of the first order by Erlang corresponding to the graph of the process. Conducted numerical simulation for the proposed mathematical models is illustrated with the plotted diagrams.

Onnipotenza divina e ordine naturale nel Medioevo
Authors: Possamai Andrea 
Published: July 2019

The present essay aims, on the one hand, to recall the reasons of anti-naturalism, intended in a metaphysical perspective, of a large part of medieval philosophical and theological reflection and, on the other hand, to show how the same type of problems, specifically those concerning the possible mutability or immutability of the past, can be employed in favour of various conflicting positions on the matter. To demonstrate this, reference was made to some thinkers who could represent emblematic positions on the theme, in particular: Pliny the Elder for the ancient world, Augustine of Hippo, Peter Damian, Bonaventure and Thomas Aquinas for the medieval era.

Published: July 2019

In this study it is aimed to
investigate the perceptions of the teacher candidates regarding democracy.
Within this research phenomenology pattern, which is one of the qualitative
research patterns, was used. The study group of the research consists of 222
teacher candidates who attend Elementary Education, Mathematics Education,
Science Education, Social Studies Education and Preschool Education, determined
with criterion sampling method among junior and senior teacher candidates. The
quantitative data was analysed with content analysis method. The metaphors
regarding democracy were categorized “democracy as vital needs”, “democracy as
material”, “democracy as nutritional source”, “democracy as the symbol of
freedom”, “democracy as abstract thinking”, “democracy as balance”, and
“democracy as negativity” considering the connection that the teacher
candidates related with democracy. Teacher candidates, who participated in the
research, from different departments explained democracy with metaphors
regarding equality, respect, life source and freedom concepts. It is seen that the teacher candidates did not
focus on especially cooperation and responsibility concepts. Also as a result of the
research it is determined that more than half of the teacher candidates did not
participate in a democratic activity in lessons at school all of their student-
life.
O caso Aída Cury: playboys e transviados como representações da juventude em tempos de modernização

Published: July 2019

Estuprada e atirada de um edifício pelos jovens
Ronaldo Castro e Cassio Murilo, a jovem Aída Cury
amanheceu o dia 14 de julho de 1958 estendida na
calçada de Copacabana. De repercussão nacional,
esse crime fez com que a delinquência juvenil de
classe média se tornasse um tópico central da grande
imprensa brasileira de fins dos anos 50. Tomados
como sintoma e produto de uma nova ordem social,
os chamados “playboys transviados” – existindo por e
através de suas representações midiáticas – ajudam a
descortinar as ambivalências de um período histórico
comumente associado a um otimismo generalizado.
O objetivo desse artigo, portanto, é perceber como
esses personagens dramatizavam as consequências
do projeto de modernização nacional baseado na
metrópole, espaço em que progresso, cosmopolitismo e
diversidade social poderiam significar promiscuidade,
vício e corrupção moral.
Case Series of Pott’s Spine Diagnosed by ZN Stain and BacTec MGIT in a Tertiary Care Hospital
Authors: Kumar Avinash , Das P. 
Published: July 2019

Introduction: Pott’s spine is a destructive form of tuberculosis and accounts for approximately half of all cases of musculoskeletal tuberculosis. Spinal Tuberculosis is most often missed due to inadequate sample and lack of clinical history. Most of the Extrapulmonary tuberculosis (EPTB) can be diagnosed by Ziehl Nelson stain (ZN) only, when clinically suspected samples are adequate and optimally stained. We are reporting four case series of spinal tuberculosis diagnosed by ZN stain and confirmed by Bactec MGIT Culture.
Material & Methods: These four clinically suspected spinal biopsis were received for ZN stain and MTB culture by MGIT.
Results: All the four spinal biopsies were found positive by ZN stain as well as by BacTec MGIT.All the four cases were HIV negative. ESR and CRP of all four cases were raised.
Discussion & Conclusion: Spinal tuberculosis can be easily diagnosed by ZN stain in resource constraint lab. Despite its common occurrence and the high frequency of long-term morbidity, there are no straight forward guidelines for the diagnosis and treatment of spinal tuberculosis. Early diagnosis and prompt treatment is necessary to prevent permanent neurological disability and to minimize spinal deformity.

Drying is the most important step to keep the compound stability in simplicia and is very influential to produce good quality igredients in the antioxidant activity contained in the simplicia. Antioxidants are oxidation-free inhibitors of free radical reactions. Parijoto is one of the plants that have antioxidant compounds.This study aims to determine the effect of drying, concentration of antioxidant activity of parijoto (Medinilla speciosa Blume) fruit. The drying method used is direct sunlight drying, indirect sunlight and oven. The antioxidant activity of ethanol extract on drying method was determined by 2,2 diphenyl-1-picrylhidrazyl (DPPH) method which is free radical. The qualitative test DPPH showed that the higher levels of ethanol extract from the three drying methods further diminished the color of DPPH solution in ethanol.The result showed thet the drying method gave different effect to the antioxidant activity of parijoto fruit which is significant(p0,05). Drying methods wich have high antioxidant activity are given by drying using oven method with an IC50 value 33,75µg/ml.

Published: July 2019

OBJECTIVEIncreased intracranial pressure (ICP) results in enlarged optic nerve sheath diameter (ONSD). In this study the authors aimed to assess the association of ONSD and ICP in severe traumatic brain injury (TBI) after decompressive craniotomy (DC).METHODSONSDs were measured by ocular ultrasonography in 40 healthy control adults. ICPs were monitored invasively with a microsensor at 6 hours and 24 hours after DC operation in 35 TBI patients. ONSDs were measured at the same time in these patients. Patients were assigned to 3 groups according to ICP levels, including normal (ICP ≤ 13 mm Hg), mildly elevated (ICP = 14–22 mm Hg), and severely elevated (ICP > 22 mm Hg) groups. ONSDs were compared between healthy control adults and TBI cases with DC. Then, the association of ONSD with ICP was analyzed using Pearson’s correlation coefficient, linear regression analysis, and receiver operator characteristic curves.RESULTSSeventy ICP measurements were obtained among 35 TBI patients after DC, including 25, 27, and 18 measurements in the normal, mildly elevated, and severely elevated ICP groups, respectively. Mean ONSDs were 4.09 ± 0.38 mm in the control group and 4.92 ± 0.37, 5.77 ± 0.41, and 6.52 ± 0.44 mm in the normal, mildly elevated, and severely elevated ICP groups, respectively (p < 0.001). A significant linear correlation was found between ONSD and ICP (r = 0.771, p < 0.0001). Enlarged ONSD was a robust predictor of elevated ICP. With an ONSD cutoff of 5.48 mm (ICP > 13 mm Hg), sensitivity and specificity were 91.1% and 88.0%, respectively; a cutoff of 5.83 mm (ICP > 22 mm Hg) yielded sensitivity and specificity of 94.4% and 81.0%, respectively.CONCLUSIONSUltrasonographic ONSD is strongly correlated with invasive ICP measurements and may serve as a sensitive and noninvasive method for detecting elevated ICP in TBI patients after DC.

Published: July 2019

The present study deals with the synthesis of nicotinic acid peptide derivatives and comparative evaluation of biological activities, such as antibacterial and antifungal. Among hetrocyclic aromatic compounds, pyridine nucleus is found in many bioactive products and incorporation of amino acids and peptides into the hetrocyclic aromatic congeners have resulted in compounds with potent activities. All the compounds were synthesized by coupling of nicotinic acids with amino acid methyl esters/dipeptides/tripeptides/tetrapeptides in presence of DCC as coupling agent and NMM as base under continuous stirring for 36 hrs. All synthesized peptide derivatives were identified on the basis of melting point range, Rf values, solubility studies, IR and 1H NMR spectral data. The antimicrobial activity of synthesized compounds was determined against bacterial strainsviz. E. Coli and S. Aureus and fungal strains viz. C. albicans and A. Niger using ciprofloxacin and fluconazole as standard respectively. All the synthesized compounds showed good to moderate antimicrobial activity at 40, 80 and 160 μg/ml. The comparative studies showed the following order of activity profile: nicotinic acid <nicotinic acid methylesters>dipeptide >tripeptide>tetrapeptide.
Keywords: Nicotinic acid, Peptides, Antimicrobial activity.
