Bootstrap Empirical Mode Decomposition with Application to CIELAB Color Images
Authors: Lum Kai-Yew
Published: September 2021

This paper proposes an alternative optimization-based EMD based on the
notions of: 1. local mean points that impose mode symmetry via a
Tikhonov regularized least-square (RLS) problem, and 2. efficient
bootstrap sifting that guarantees asymptotic convergence of the
mean envelope to the local mean points, regardless of regularization.
Mathematical proof of convergence and a straightforward extension to the
2D-multivariate setting and CIELAB color image sare presented.
Performance is demonstrated with a univariate signal and two images.
Spectral analysis confirms coordinated feature extraction among image
components, and separation of spatial spectra among the intrinsic mode
functions.
The bureaucratic rationalization. On the “intelligent stupidity”
Authors: Barison Marcello
Published: September 2021

Focusing on the problem of bureaucracy as a striking example of the ‘necessary stupidity’ that real-life forces us to tolerate, the philosophical meaning of Musil’s «intelligent stupidity» will be discussed. To a closer confrontation with the text, and with passages from (italic) Man Without Qualities (/italic) that are particularly relevant to the theme of the relationship between stupidity and bureaucracy, a number of reflections will be anteposed in order to highlight how, by making the concepts of liberalism and bureaucracy react to each other, it is possible to sketch a first outline of that aporetic of stupidity that seems to characterise so substantially the behaviour of modern man.
The Optical House of Tactile: The Bricolage-Like Response to COVID-19
Authors: Innocenti Marco
Published: September 2021

This paper aims to analyse how COVID-19 pandemic is changing our perception of reality. It starts looking at our situation from the point of view of Riegl’s distinction between optical and tactile, and then it compares the nature of the relationship between these two approaches to Lévi-Strauss’s description of bricolage. Our current world-view turns out to be not only an optic one, because the optical approach is just the means by which we can articulate a private and social life messed up by Coronavirus. Thereby, optical takes care of tactile without replacing it, and this article draws parallels between this aspect and language as described by Heidegger. Finally, after having argued the presence of an aura in this “optical house of tactile” in both Walter Benjamin’s and Hito Steyerl’s forms, this article tries to figure out how this perspective could last beyond the end of this emergency.
A noble anarchy. Musil and the metaphor between Spengler and Rilke
Authors: Gambaro Giacomo
Published: September 2021

This paper aims to examine the relationship between stupidity and massification in Robert Musil’s thinking moving from the speech Über die Dummheit (1937). According to the definition of stupidity as a historical epidemic associated with emotions, I take into account the essays of the earlies twenties of the XX century, in which the author interrogates the connection between the “non rational sphere” and the nationalist identity in the context of civilization (Zivilisation). To explain this connection, I highlight the centrality that Musil ascribes to the method of “analogy” in criticizing Spengler’s thought to clarify how the welding of the dimension of “feeling” (Gefühl) and the abstract idea of “national identity” occurs. Based on Musil’s essay dedicated to Rilke (1927), I illustrate the different type of bonds produced by “metaphor” (Gleichnis) to define an alternative concept of community based on the common lack of quality and foundation.
Alteration of the Touch Into a Gaze - Reading Through the Drawing
Authors: Šurbatović Sonja
Published: September 2021

Studying the touch as a sense developed by contact, and the necessity to redefine it, due to the global pandemic and social dissonance that occurred is the topic of this text. Questioning the approach to drawing under the influence of remoteness addresses the need to look closely, to get personal with the drawing, a manifestation of experience. Drawing of intimacy, evaluate concepts of encounter and isolation posing the question of whether we can experience the closeness of the other through the embodiment of the experience in the drawing. Re-examining tactile sensation observed through the obstacle of corporeal distance, a reflection of intimate experiences and spaces opens up for a new interpretation - of touch without the touch. Can this obstacle transform touch into gaze; and can an image in its making, construct a tactile sensation? Intertwining theoretical and practical approach, this text witness drawing and its visual consumption in space of violated closeness.

Published: September 2021

Physiological features were examined of a 20-year-old Vitis vinifera ‘Italia’ table grape vineyard cropped in Apulia, Italy. Healthy vines with no foliar symptoms and any indications of wood or berry alterations, vines with natural wood infections by Phaeoacremonium minimum (syn. P. aleophilum) and Phaeomoniella chlamydospora showing brown wood streaking symptoms, and vines naturally infected with P. minimum, P. chlamydospora and Fomitiporia mediterranea with brown wood streaking and white rot symptoms, were surveyed. Bleeding xylem sap, collected at bud-break from healthy vines showed the greatest total ascorbic acid level, while vines with brown wood streaking and white rot had the greatest viscosity coefficient, glutathione concentration, and plant growth regulator activities. Compared to healthy vines, leaves of wood affected vines, sampled during the unfolded leaf, fruit setting, cluster closing and bunch ripening vine growth stages, had reduced fresh and dry weights, total chlorophyll concentrations, and increased leaf surface area. Low ascorbic acid and reduced glutathione concentrations, weak redox state, and moderate levels of dehydroascorbic acid and oxidized glutathione were also detected in these vines. Analyses also detected reduced activities of dehydroascorbate reductase, ascorbate free radical reductase and glutathione reductase in diseased vines. The cell membrane damage, associated with lipid peroxidation, was coupled with high hydrogen peroxide concentrations. These changes could contribute to the cell death of leaves and foliar symptom development. The ascorbate-glutathione cycle supports grapevine susceptibility to Esca complex-associated fungi.

Model for construction project delay occurrence (PDO)
Authors:   Kuwait University, Civil Engineering Department, Safat 17269, Kuwait, Soliman Ehab , Alrasheed Khaled ,   Kuwait University, Civil Engineering Department, Safat 17269, Kuwait
Published: September 2021

Extensive research work was conducted in relation with evaluating and ranking delay causes in construction projects, but limited research was performed to discuss the delay issue in theory. This paper discusses the theoretical basis for how delay occurs and propagates during project construction. A set of suggested assumptions were proposed to build a theoretical model for delay occurrence. These assumptions were driven from the analysis of construction project environment, and the concept of project implementation. The construction delay occurrence (PDO) model assumes that some of the root delay causes can convert by themselves and/or other triggers toward direct delay causes. Contractor management deficiency, project contract and procurement strategy, and contractor financial problems are examples of the root delay causes, which have significant influence on project delay and resource availability. The model assumes that construction resources unavailability is the underpinning driver for project delay. Graphical presentation of the PDO model is used to illustrate how delay is generated, propagated during the project life, and converted to be a real and physical delay. Interview questionnaires were used to verify the model bases. This is followed by statistical analysis to ascertain the model assumptions and Delphi technique to confirm questionnaire results. The correlation factors for the two rounds of questionnaires showed that there is a great enhancement for respondents’ answers regarding the effect of resource shortage on root delay causes. The study shows that the proposed set of root delay causes and their effect on project delay and their influence on resource availability were statistically accepted. The study results can be used as a basis for assessing root delay causes and predicting the prone of a project to delay before it starts.

Published: September 2021

Freshwater supply is a major challenge in regions with limited water resources and extremely arid climatic conditions. The objective of this study is to model the monthly water demand in Kuwait using the nonlinear autoregressive with exogenous input (NARX) neural network approach. The country lacks conventional surface water resources and is characterized by extremely arid climate. In addition, it has one of the fastest growing populations. In this study, linear detrending is performed on the water consumption time series for the period from January 1993 to December 2018 to eliminate the influence of population growth before application to the NARX model. Monthly temperature data are selected as exogenous input to the NARX model, because they are strongly associated with the water consumption data. Correlation analyses are performed to determine the input and feedback delays of the NARX model. The results demonstrate that the recurrent NARX model is efficient and robust for forecasting the short-term water demand, with a Nash-Sutcliffe (NS) coefficient of 0.837 in the validation period. Seasonal model assessment shows that the model performs best during the critical summer season. The NARX-based recurrent model is established as a powerful and promising tool for predicting urban water demand. Thus, it can efficiently aid the development of resilient water supply plans.

Local scour is an important problem for hydraulic structures. The local scour in the downstream of dams causes problems such as the damage of the dam body stabilization, erosion of the slopes, and the submergence of the turbines. There are many studies investigating the local scour prediction of the downstream of the hydraulic structures, but in recent years, these studies have been replaced by studies of local scour reduction. The new idea of confining the bed materials using the geocell is becoming a popular solution. This solution can be especially used for the reinforcement of the soils. In this study, the preventability of the local scour downstream of chute channel by cellular confinement system, also known as geocell, was investigated. As a result, in case of using geocell, percentage reduction of the maximum scour depth up to 40.63% was observed.
Thermal buckling analysis of cross-ply plates based on new displacement field
Authors:   Department of Mechanical Engineering, University of Baghdad, Baghdad, 00964, Iraq, Majeed Widad Ibraheem
Published: September 2021

A higher-order displacement field is used for the analysis of the thermal buckling of composite plates subjected to thermal load; it is based on a constant ‘‘m’’, which is optimized to get results relatively close to those given by 3D elasticity theory. Adequate transverse shear strains distribution through the thickness and free stress surfaces of the plate is satisfied using this theory. Hamilton’s principle is used to derive equations of motion, which are solved using Navier-type series for simply supported plates. Thermal buckling of cross-ply laminates with various (α2 / α1) ratios, number of layers, aspect ratios, E1/E2 ratios, and stacking sequence for thick and thin plates is studied in detail. It is concluded that the obtained results using this displacement field are close to those calculated by 3D elasticity theory and other shear deformation plate theories when m=0.05.

Authors:   Department of Mechanical Engineering, Engineering Faculty, Alanya Alaaddin Keykubat University, Antalya, 07450, Turkey, Beylergil Bertan
Published: September 2021

Fiber reinforced composites have been widely used in automotive industry since they offer significant weight reduction, low manufacturing and tooling cost, and better integration of parts compared to metal counterparts. In this study, design optimization of a hybrid aluminum/composite drive shaft subjected to torsion was carried out using ANSYS Workbench with ACP module. The numerical validation of finite element (FE) model was carried out by means of theoretical, experimental, and numerical studies in the literature. The ply material, lay-up orientations, and thickness of aluminum layer were considered as design variables. The geometric parameters in design were the length and inner diameter of the drive shaft. Two important design constraints, the minimum first mode natural frequency and design torque, were considered to satisfy the design requirements of a rear-wheel drive shaft used in automotive industry. The optimum design variables were determined by using screening method. The optimum design parameters (length, inner diameter, ply angle, and material) were presented in tabular form. Compared to nonoptimized scenario, the optimized solution reduced the cost of the hybrid composite drive shaft about 30% without ignoring the design requirements.

Nickel Titanium (NiTi) orthodontic wires are the most accurate initial wires to align the teeth by producing the less painful bone remodeling. Coupling their mechanical response, while they are engaged in the oral cavity, with the bone remodeling would permit to elucidate the reaction and the effect of this wire during the orthodontic tooth alignment. Therefore, A two-dimensional numerical long-term orthodontic tooth correction was performed to simulate a tooth intrusion movement. This simulation was achieved by taking into consideration the effect of an orthodontic appliance action on three multiteeth models. The superelastic behavior of the NiTi wire was integrated in the computer software ABAQUS via a UMAT subroutine. The orthodontic arch was initially deformed to simulate its insertion in brackets and then unloaded to apply an orthodontic load and produce initial tooth displacement. A bone remodeling process was implemented to displace the teeth depending on the strain within the periodontal ligament. The results were obtained for a treatment period of 30 days. The NiTi wire was able to recuperate its initial position, and the teeth were aligned. The numerical results of the teeth displacement were in agreement with what is expected to be produced during the alignment phase.

The ageing drivers’ population is increasing rapidly, and they are exposed to disabilities due to degenerative processes, thus affecting their driving performance. The main objective of this study is to determine the mental workload of ageing drivers, while the second objective is to compare the mental workload between ageing drivers and control group. The methodology consisted of on-the-road experimental driving tasks that comprised three levels of situation complexity. The NASA-Task Load Index (NASA-TLX) and electroencephalogram (EEG) were measured on 30 drivers. The NASA-TLX scores revealed that the ageing drivers’ mean physical demand score was the highest compared to others in moderately complex situation and very complex situation, scoring 37.25 and 43.50, respectively. Meanwhile, for electroencephalogram signals’ fluctuation, results showed that situation complexity had significant effects on RPθ and RPα of channel locations FZPZ and O1O2. There was a significant difference in the weighted workload scores for the ageing drivers and control group in simple situation, while there was no significant difference found in RPθ and RPα bands at all channel locations. The findings would be beneficial as a guideline for designers, manufacturers, developers, and policy makers in designing better driving environment for ageing drivers.

Acute gastroenteritis (AGE) causes significant health and economic burden on society. The aim of this study is to estimate households’ direct and indirect expenditures on AGE and its predicted factors. This cross-sectional study was conducted between December 2019 and March 2020 using a bilingual proforma distributed using Survey Monkey among individuals with self-reported AGE in all 14 states of Malaysia. The finding revealed the average expenditure for a single episode of AGE was RM395.58 (± SD 798.02). The mean indirect expenditure was higher at RM259.14 (± SD 379.92) vs. direct expenditure of RM136.44 (± SD 596.47). The highest expenditure was seen among those who obtained inpatient care. The multiple linear regression analysis showed that household income (RM0.13; 95% CI: 0.01, 0.27; p=0.043) and type of healthcare facility (private vs government) (RM1842.05; 95% CI: 395.13, 3288.98; p=0.014) had a significant association with households’ total health expenditure on AGE. Acute gastroenteritis incurred substantial costs on all affected households regardless of care-seeking modalities. Interestingly, the main economic burden of AGE was the indirect cost of productivity loss; interpreted in terms of days away from work. In conclusion, AGE instigated an economic burden on both households and employers. The household income and type of facility were found to be significant factors associated with the households’ health expenditures due to AGE. This study recommends food safety awareness among the public and enforcement of safe food handling practices among food vendors and industries.

Published: September 2021

Tobacco-related diseases are the leading causes of death worldwide. Tobacco use must be reduced and controlled. Due to its low cost, internet intervention has a high probability of attracting a large number of smokers, however, more research is needed to determine its most effective use. The purpose of this study was to analyze the efficacy of online smoking cessation websites in Malaysia based on assessment by Kuantan smokers. A cross-sectional study using a mix method was conducted among smokers in Kuantan, Pahang. The evaluation is divided into two phases: phase I is the selection of a website by a content expert, and phase II is the review of a selected local website by a local respondent. Random purposive sampling among 35 smokers were recruited in phase 2. There were predetermined criteria in both phase. Website search was conducted thru identified keyword using search engine google. In phase 2, the selected good score website will be assessed by local smokers based on validated checklist. Three websites which were JomQuit.com, Nicorette.com and Quit Smoking Clinic IJN was selected for the review. The website JomQuit.com was identified as comprehensive anti-smoking website in Malaysia. The Malaysian online smoking cessation was believed to be helpful to quit smoking, provide interesting content and information, increase awareness and increase promotion. Regular website assessments must be performed on a regular basis to ensure that the information on the website is applicable to local communities and for content improvement purposes.

Published: September 2021

Despite the effectiveness of mammography for early breast cancer detection, its’ utilization among Malaysian women remains low. Health beliefs are closely related to health screening behavior. Hence, it is important that health beliefs are employed when exploring mammography screening behavior. Thus, the study utilized HBM constructs in predicting the variance in adoptive behavior of mammography. A multi-stage, stratified random sampling method was utilized to select the polyclinics in Kuantan, Pahang. Using sample size calculation at 5% type 1 error, p < 0.05 and absolute error at 2%, 520 Malaysian women aged 35 to 70 years were randomly selected. Sets of copyrighted, validated questionnaire were used to obtain the data. Structural equation modeling using Mplus was used to test the model. All health beliefs were found to significantly influence the behavioral adoption of mammography screening. Socio-demographic factors (married women) were found to moderate significantly the relationship between perceived susceptibility and behavioral adoption of mammography. Further, knowledge and married women were found to significantly affect self-efficacy. Additionally, perceived severity, motivator factors and perceived benefits were found to significantly influence self-efficacy and that self-efficacy significantly influences the behavioral adoption of mammography screening. However, a negative correlation was found between perceived severity and perceived barriers on the behavioral adoption of mammography. The model can be used as an interventional tool in designing promotional and educational programs to encourage women to adopt mammography screening.

Published: September 2021

Microcontroller based trigger control circuit for fast pulsing of electrode potentials on wide range of time scales has been designed, installed, and tested for electron plasma experiments which are carried out in partial toroidal trap SMall Aspect Ratio Toroidal Electron plasma EXperiment in C – shaped geometry (SMARTEX – C), a device to create and confine non-neutral plasma (electron plasma). The sequence of trap operation is inject-hold-dump for which electrodes need to be pulsed with applied voltages at a high switching speed of few nanoseconds. Also this sequence of operation needs to be controlled over a very wide range of time scales from few microseconds to few seconds. As the available COTS (Commercial-Off-The-Shelf) high voltage DC power supplies generally do not provide this feature of fast switching at nanosecond time scale, MOSFET based circuit is developed which provides fast switching in the range of 20 – 100 nanoseconds of high voltages (200Vdc - 500Vdc) of multiple electrodes. The timing pulse widths of these trigger pulses are controlled using a microcontroller-based circuit. This experimental set-up also requires the triggering of a high current dc power supply used for an Electro-magnet (Toroidal Field Coil) to generate a toroidal magnetic field, at the start of this experiment. For this purpose, a Silicon Controlled Rectifier (SCR) based circuit is used. The gate pulse to trigger the SCR circuit is also generated from this microcontroller-based circuit. National Instrument’s LabVIEW software based Graphical User Interface (GUI) is developed for triggering the SCR and electrodes with a programmable time period through the serial link.

Ni-Cu sulfide mineralization and PGM from the Samapleu mafic-ultramafic intrusion, Yacouba complex, western Ivory Coast
Authors: Gouedji Franck , Picard Christian , Audet Marc Antoine , Augé Thierry , Spangenberg Jorge
Published: September 2021

The mafic-ultramafic Samapleu deposits of the Yacouba complex, which host nickel, copper sulfides, and platinum-group minerals, are located in the Biankouma-Silipou region, western Ivory Coast. These intrusions originate from the mantle and would have been established during the Proterozoic (2.09 Ga) around 22 km deep within the Archean granulites (3.6–2.7 Ga) which at least partially contaminated them.

Platinum-group and sulfide minerals from the Samapleu deposits were studied using optical microscopy, scanning electron microscopy, the electronic microprobe, X-ray fluorescence, fire assay, and a Thermo Fisher Scientific Delta S isotope ratio mass spectrometer system.

The sulfide mineralization (mainly pyrrhotite, pentlandite, chalcopyrite ± pyrite) is mainly disseminated with, in places, semi-massive to massive sulfide veins. It is especially abundant in pyroxenite horizons with net or breccia textures.

The isotopic ratios of sulfur measured from the sulfides (an average of 0.1‰), the R factor (between 1500 and 10,000), and the Cu/Pd ratios indicate a mantle source.

Thus, the sulfides would have formed from sulfide liquids produced by immiscibility from the silicate mantle magma under mafic-ultramafic intrusion emplacement conditions and with possible geochemical modification of the magmas by assimilation of the surrounding continental crust.

The platinum-group minerals (michenerite, merenskyite, moncheite, Co-rich gersdorffite, irarsite, and hollingworthite) are mainly associated with the sulfide phases. The nature of the platinum-group minerals is indicative of the probable role of late-magmatic hydrothermal fluids during the mineralizing process.

Wildcatite (IMA2020–019) is a new calcium–iron(III) tellurate discovered at the Wildcat prospect in the Detroit district, Juab County, Utah. Wildcatite may take on a variety of appearances, ranging from transparent orange to brown coatings or masses to earthy, white polycrystalline coatings filling jasperoid fracture surfaces. Coatings of wildcatite are generally less than 0.1 mm thick and may cover up to 5 cm2, while nanoscale crystallites of wildcatite may form translucent red-brown “crystals” up to 0.1 mm. Wildcatite is found associated with gold, calcite, aragonite, native tellurium, manganese oxides, iron oxides, rare clinobisvanite, beyerite, coronadite, the Te oxides paratellurite and tellurite, and the Te oxysalts andymcdonaldite, burckhardtite, carlfriesite, eckhardite, frankhawthorneite, khinite, mcalpineite, tlapallite, and xocolatlite. The strongest powder diffraction lines are [dobsÅ(Iobs)(hkl)]: 3.33(100)(011), 2.60(55)(110), 2.30(59)(111), 2.05(33)(021), and 1.80(88)(112). The average size of wildcatite crystallites is 13 nm, thus the crystal structure of wildcatite was solved by Rietveld refinement, converging to a final RB value of 3.14%. The empirical formula of wildcatite, as determined by electron probe microanalysis and Rietveld refinement, is Ca0.98Bi3+0.02Pb0.01Fe3+0.73Mg0.05Mn2+0.02Zn0.01Cu0.00Te6+1.15Sb5+0.02Si0.01O5.44H0.56, simplified to the ideal formula of CaFe3+Te6+O5(OH). Wildcatite is trigonal, crystallizing in the space group P1m, with a = 5.2003(14) Å, c = 4.9669(14) Å, V = 116.3(1) Å3 and Z = 1. Wildcatite is structurally very similar to rosiaite (PbSb2O6), possessing a honeycomb-like two-dimensional framework of edge-sharing Fe3+O6 and Te6+O6 octahedra, sandwiching octahedrally coordinated Ca2+ cations. Minor OH substitution (∼10%) at the O sites is required for charge balance in wildcatite.

One-member sentences and their communicative potential in professional discourse
Authors: Крюкова Л.Б. , Губайдуллина А.Н.
Published: September 2021

В статье рассматривается структурно-семантическая организация отдельных типов односоставных предложений в профессиональной коммуникации. Анализ функциональной нагрузки и коммуникативного потенциала исследуемых конструкций проводится с дискурсивных позиций. В качестве предмета лингвистического анализа выбраны строевые команды, представляющие собой односоставные и неполные грамматические структуры, реализация которых напрямую обусловлена стандартизованностью и субординативностью военной речи, однозначностью интерпретации и отсутствием вариативности. В фокусе внимания – инфинитивные и определенно-личные синтаксические единицы, ориентированные на вертикальную модель коммуникации. Отмечается четко выраженная жанровая обусловленность процессов интеръективации и вербализации. Демонстрируется, что императивный характер военного дискурса определяет семантику и коммуникативную направленность односоставных и неполных словесных конструкций.

The article deals with the structural and semantic organization of certain types of one-member sentences in professional communication. The functional load and the communicative potential of the sentences are analyzed from a discursive standpoint. The object of linguistic analysis are drill commands, which are one-member and incomplete grammatical structures. The standardization and subordinality of military speech, unambiguous interpretation and lack of variability directly affect drill command verbalization forms. The focus is on infinitive and definite personal syntactic units oriented towards the vertical communication model. The interjectivation and verbalization processes are clearly caused by the genre. The article shows that the imperative nature of military discourse determines the semantics and communicative orientation of one-member and incomplete verbal constructions.
Ways for russian and vietnamese military terminology formation
Authors: Доан Т.А.
Published: September 2021

Терминология представляет собой обширный класс специальной лексики. Термины противопоставлены общей лексике в том отношении, что они связаны с определенной научной концепцией. В связи с развитием форм общественной жизни, успехом хозяйственной, культурной деятельности, быстрым развитием военной науки появляются новые профессионально соответствующие термины. Система военной терминологии очень разнообразна и в русском, и во вьетнамском языках. На основе систематизации, обобщения, анализа русских и вьетнамских военных терминов данная статья поставляет и решает задачу рассмотреть пути формирования военной терминологии русского и вьетнамского языков, что, как нам хотелось бы, может быть предпосылкой для дальнейшего изучения и грамотного употребления терминов в обоих языках.

Terminology is an extensive class of specialized vocabulary. Terms are contrasted with general vocabulary in the sense that they are associated with a specific scientific concept. As a result of the development of forms of social life, economic, cultural activities, and military science, new professionally relevant terms appear. Therefore, military terminology is very diverse in both Russian and Vietnamese languages. Based on the systematization, generalization, analysis of Russian and Vietnamese military terms, this article proposes some problems and also suggests some solutions in order to consider ways of forming Russian and Vietnamese military terminology. We hope that this article could be a prerequisite for further study and competent use of terms in both languages.

Brain death is physiological loss of function of all intracranial structures above foramen magnum. Imaging is ancillary and are not substitute for clinical diagnosis of brain death. MRI can be useful supplementary diagnostic test for diagnosing brain death especially in cases where bed side clinical tests cannot be performed. No single sign in MRI is specific for brain death. Tonsillar herniation, loss of flow void in bilateral internal carotid arteries and vertebral arteries, swollen cortical gyri, edematous, cerebellar foliae with white matter hyperintensities, effacement of the ventricular system, uncal herniation compressing over the midbrain, brain stem swelling, dilated veins showing increased susceptibility phenomenon due to increase deoxyhemoglobin, diffuse restriction in cerebral cortex are some of the feature of brain death we present the imaging signs brain which we came across in two patients.

Multiple Sclerosis is a neurological disorder consisting in autoimmune and inflammatory manifestations. Its evolution is characterized by axonal demyelination among the central nervous system. A growing body of evidence suggests lately that vitamin D deficiency is a very common condition in Multiple Sclerosis. On the other hand, during the last years, several studies have shown a correlation between high vitamin D serum levels and a decreased risk either for developing this illness, or preventing its evolution towards disability. Vitamin D is currently being considered an important environmental factor for this disease, therefore being widely debated whether its supplementation would actually be benefic, and if yes, what results can be expected in such a therapeutic approach. Our brief look upon some of the latest results in the field of research for this matter is intended to synthesize what is known at this moment and what future directions would be.
