Authors: Vallance Thomas M. , Ravishankar Divyashree , Albadawi Dina A. I. , Osborn Helen M. I. , Vaiyapuri Sakthivel
Published: June 2019

Cardiovascular diseases represent a major cause of mortality and morbidity in the world, and specifically, thrombotic conditions such as heart attacks and strokes are caused by unwarranted activation of platelets and subsequent formation of blood clots (thrombi) within the blood vessels during pathological circumstances. Therefore, platelets act as a primary therapeutic target to treat and prevent thrombotic conditions. Current treatments are limited due to intolerance, and they are associated with severe side effects such as bleeding complications. Hence, the development of novel therapeutic strategies for thrombotic diseases is an urgent priority. Flavonoids are naturally occurring plant-derived molecules that exert numerous beneficial effects in humans through modulating the functions of distinct cell types. However, naturally occurring flavonoids suffer from several issues such as poor solubility, lipophilicity, and bioavailability, which hinder their efficacy and potency. Despite these, flavonoids act as versatile templates for the design and synthesis of novel molecules for various therapeutic targets. Indeed, several synthetic flavonoids have recently been developed to improve their stability, bioavailability, and efficacy, including for the modulation of platelet function. Here, we provide insight into the actions of certain natural flavonoids along with the advantages of synthetic flavonoids in the modulation of platelet function, haemostasis, and thrombosis.
Influence of the Rearing Host on Biological Parameters of Trichopria drosophilae, a Potential Biological Control Agent of Drosophila suzukii
Authors: Boycheva Woltering Svetlana , Romeis Jörg , Collatz Jana
Published: June 2019

Trichopria drosophilae is a pupal parasitoid that can develop in a large number of drosophilid host species including the invasive pest Drosophila suzukii, and is considered a biological control agent. We investigated the influence of the rearing host on the preference and performance of the parasitoid, using two different strains of T. drosophilae, reared on D. melanogaster or D. suzukii for approximately 30 generations. Host switching was employed to assess the impact of host adaptation on T. drosophilae performance. In a no-choice experimental setup, T. drosophilae produced more and larger offspring on the D. suzukii host. When given a choice, T. drosophilae showed a preference towards D. suzukii, and an increased female ratio on this host compared to D. melanogaster and D. immigrans. The preference was independent from the rearing host and was confirmed in behavioral assays. However, the preference towards D. suzukii increased further after a host switch from D. melanogaster to D. suzukii in just one generation. Our data indicate that rearing T. drosophilae for several years on D. melanogaster does not compromise its performance on D. suzukii in the laboratory. However, producing a final generation on D. suzukii prior to release could increase its efficacy towards the pest.
Hormonal Contraceptives, Female Sexual Dysfunction, and Managing Strategies: A Review

Published: June 2019

In recent decades, hormonal contraceptives (HC) has made a difference in the control of female fertility, taking an unequivocal role in improving contraceptive efficacy. Some side effects of hormonal treatments have been carefully studied. However, the influence of these drugs on female sexual functioning is not so clear, although variations in the plasma levels of sexual hormones could be associated with sexual dysfunction. Permanent hormonal modifications, during menopause or caused by some endocrine pathologies, could be directly related to sexual dysfunction in some cases but not in all of them. HC use seems to be responsible for a decrease of circulating androgen, estradiol, and progesterone levels, as well as for the inhibition of oxytocin functioning. Hormonal contraceptive use could alter women’s pair-bonding behavior, reduce neural response to the expectation of erotic stimuli, and increase sexual jealousy. There are contradictory results from different studies regarding the association between sexual dysfunction and hormonal contraceptives, so it could be firmly said that additional research is needed. When contraceptive-related female sexual dysfunction is suspected, the recommended therapy is the discontinuation of contraceptives with consideration of an alternative method, such as levonorgestrel-releasing intrauterine systems, copper intrauterine contraceptives, etonogestrel implants, the permanent sterilization of either partner (when future fertility is not desired), or a contraceptive ring.

Published: June 2019

Outcome measures reported by patients, clinicians, and lay-observers can help to tailor treatment plans to meet patients’ needs. This study evaluated orthognathic surgery (OGS) outcomes using pre- and post-OGS patients’ (n = 84) FACE-Q reports, and a three-dimensional facial photograph-based panel assessment of facial appearance and psychosocial parameters, with 96 blinded layperson and orthodontic and surgical professional raters, and verified whether there were correlations between these outcome measurement tools. Post-OGS FACE-Q and panel assessment measurements showed significant (p < 0.001) differences from pre-OGS measurements. Pre-OGS patients’ FACE-Q scores were significantly (p < 0.01) lower than normal, age-, gender-, and ethnicity-matched individuals’ (n = 54) FACE-Q scores, with no differences in post-OGS comparisons. The FACE-Q overall facial appearance scale had a low, statistically significant (p < 0.001) correlation to the facial-aesthetic-based panel assessment, but no correlation to the FACE-Q lower face and lips scales. No significant correlation was observed between the FACE-Q and panel assessment psychosocial-related scales. This study demonstrates that OGS treatment positively influences the facial appearance and psychosocial-related perceptions of patients, clinicians and lay observers, but that there is only a low, or no, correlation between the FACE-Q and panel assessment tools. Future investigations may consider the inclusion of both tools as OGS treatment endpoints for the improvement of patient-centered care, and guiding the health-system-related decision-making processes of multidisciplinary teams, policymakers, and other stakeholders.
Population Approaches Targeting Metabolic Syndrome Focusing on Japanese Trials
Authors: Nishizawa Hitoshi , Shimomura Iichiro
Published: June 2019

The clinical importance of assessment of metabolic syndrome lies in the selection of individuals with multiple risk factors based on visceral fat accumulation, and helping them to reduce visceral fat. Behavioral modification by population approach is important, which adds support to the personal approach. The complexity of visceral fat accumulation requires multicomponent and multilevel intervention. Preparation of food and physical environments could be useful strategies for city planners. Furthermore, actions on various frameworks, including organizational, community, and policy levels, have been recently reported. There are universal public health screening programs and post-screening health educational systems in Japan, and diseases management programs in Germany. Understanding one’s own health status is important for motivation for lifestyle modification. The U.S. Preventive Services Task Force recommends that primary care practitioners screen all adults for obesity and offer behavioral interventions and intensive counseling. Established evidence-based guidelines for behavioral counseling are needed within the primary care setting.
Campylobacter at the Human–Food Interface: The African Perspective
Authors: Asuming-Bediako Nikki , Parry-Hanson Kunadu Angela , Abraham Sam , Habib Ihab
Published: June 2019

The foodborne pathogen Campylobacter is a major cause of human gastroenteritis, accounting for an estimated annual 96 million cases worldwide. Assessment of the true burden of Campylobacter in the African context is handicapped by the under-reporting of diarrhoeal incidents and ineffective monitoring and surveillance programmes of foodborne illnesses, as well as the minimal attention given to Campylobacter as a causative agent of diarrhoea. The present review of the literature highlights the variability in the reported occurrence of Campylobacter in humans and animal food sources across different countries and regions in Africa. Campylobacter infection is particularly prevalent in the paediatric population and has been isolated from farm animals, particularly poultry, and foods of animal origin. The reported prevalence of Campylobacter in children under the age of five years ranges from 2% in Sudan to 21% in South Africa. In poultry, the prevalence ranges from 14.4% in Ghana to 96% in Algeria. This review also highlights the alarming trend of increased Campylobacter resistance to clinically important antimicrobials, such as ciprofloxacin and erythromycin, in humans and food animals in Africa. This review adds to our understanding of the global epidemiology of Campylobacter at the human–food animal interface, with an emphasis from the African perspective. Interinstitutional and intersectoral collaborations, as well as the adoption of the One Health approach, would be useful in bridging the gaps in the epidemiological knowledge of Campylobacter in Africa.
Long-Range, High-Resolution Camera Optical Design for Assisted and Autonomous Driving
Authors: Sahin Furkan
Published: June 2019

High-quality cameras are fundamental sensors in assisted and autonomous driving. In particular, long-range forward-facing cameras can provide vital information about the road ahead, including detection and recognition of objects and early hazard warning. These automotive cameras should provide high-resolution images consistently under extreme operating conditions of the car for robust operation. This paper aims to introduce the design of fixed-focus, passively athermalized lenses for next-generation automotive cameras. After introducing an overview of essential and desirable features of automotive cameras and state-of-the-art, based on these features, two different camera designs that can achieve traffic sign recognition at 200 m distance are presented. These lenses are designed from scratch, with a unique design approach that starts with a graphical lens material selection tool and arrives at an optimized design with optical design software. Optical system analyses are performed to evaluate the lens designs. The lenses are shown to accomplish high contrast from − 40 °C to 100 °C and allow for a 4 × increase in resolution of automotive cameras.
Conservative Sensor Error Modeling Using a Modified Paired Overbound Method and its Application in Satellite-Based Augmentation Systems
Authors: Zhang Yan , Xiao Zhibin , Li Pengpeng , Tang Xiaomei , Ou Gang
Published: June 2019

Conservative sensor error modeling is of great significance in the field of safety-of-life. At present, the overbound method has been widely used in areas such as satellite-based augmentation systems (SBASs) and ground-based augmentation systems (GBASs) that provide integrity service. It can effectively solve the difficulties of non-Gaussian and non-zero mean error modeling and confidence interval estimation of user position error. However, there is still a problem in that the model is too conservative and leads to the lack of availability. In order to further improve the availability of SBASs, an improved paired overbound method is proposed in this paper. Compared with the traditional method, the improved algorithm no longer requires the overbound function to conform to the characteristics of the probability distribution function, so that under the premise of ensuring the integrity of the system, the real error characteristics can be more accurately modeled and measured. The experimental results show that the modified paired overbound method can improve the availability of the system with a probability of about 99%. In view of the fact that conservative error modeling is more sensitive to large deviations, this paper analyzes the robustness of the improved algorithm in the case of abnormal data loss. The maximum deviation under a certain integrity risk is used to illustrate the effectiveness of the improved paired overbound method compared with the original method.

Authors: Pena Danilo , Lima Carlos , Dória Matheus , Pena Luan , Martins Allan , Sousa Vicente
Published: June 2019

In general, acoustic channels are not Gaussian distributed neither are second-order stationary. Considering them for signal processing methods designed for Gaussian assumptions is inadequate, consequently yielding in poor performance of such methods. This paper presents an analysis for audio signal corrupted by impulsive noise using non-Gaussian models. Audio samples are compared to the Gaussian, α -stable and Gaussian mixture models, evaluating the fitting by graphical and numerical methods. We discuss fitting properties as the window length and the overlap, finally concluding that the α -stable model has the best fit for all tested scenarios.
Improving Optical Measurements: Non-Linearity Compensation of Compact Charge-Coupled Device (CCD) Spectrometers
Authors: Nehir Münevver , Frank Carsten , Aßmann Steffen , Achterberg Eric P.
Published: June 2019

Charge-coupled device (CCD) spectrometers are widely used as detectors in analytical laboratory instruments and as sensors for in situ optical measurements. However, as the applications become more complex, the physical and electronic limits of the CCD spectrometers may restrict their applicability. The errors due to dark currents, temperature variations, and blooming can be readily corrected. However, a correction for uncertainty of integration time and wavelength calibration is typically lacking in most devices, and detector non-linearity may distort the signal by up to 5% for some measurements. Here, we propose a simple correction method to compensate for non-linearity errors in optical measurements where compact CCD spectrometers are used. The results indicate that the error due to the non-linearity of a spectrometer can be reduced from several hundred counts to about 40 counts if the proposed correction function is applied.
Nano-Cracked Strain Sensor with High Sensitivity and Linearity by Controlling the Crack Arrangement
Authors: Jung Hyunsuk , Park Chan , Lee Hyunwoo , Hong Seonguk , Kim Hyonguk , Cho Seong J.
Published: June 2019

Studies on wearable sensors that monitor various movements by attaching them to a body have received considerable attention. Crack-based strain sensors are more sensitive than other sensors. Owing to their high sensitivity, these sensors have been investigated for measuring minute deformations occurring on the skin, such as pulse. However, existing studies have limited sensitivity at low strain range and nonlinearity that renders any calibration process complex and difficult. In this study, we propose a pre-strain and sensor-extending process to improve the sensitivity and linearity of the sensor. By using these pre-strain and sensor-extending processes, we were able to control the morphology and alignment of cracks and regulate the sensitivity and linearity of the sensor. Even if the sensor was fabricated in the same manner, the sensor that involved the pre-strain and extending processes had a sensitivity 100 times greater than normal sensors. Thus, our crack-based strain sensor had high sensitivity (gauge factor > 5000, gauge factor (GF = (△R/R0)/ε), linearity, and low hysteresis at low strain (<1% strain). Given its high sensing performance, the sensor can be used to measure micro-deformation, such as pulse wave and voice.
Methods for Simultaneous Robot-World-Hand–Eye Calibration: A Comparative Study
Authors: Ali Ihtisham , Suominen Olli , Gotchev Atanas , Morales Emilio Ruiz
Published: June 2019

In this paper, we propose two novel methods for robot-world-hand–eye calibration and provide a comparative analysis against six state-of-the-art methods. We examine the calibration problem from two alternative geometrical interpretations, called ‘hand–eye’ and ‘robot-world-hand–eye’, respectively. The study analyses the effects of specifying the objective function as pose error or reprojection error minimization problem. We provide three real and three simulated datasets with rendered images as part of the study. In addition, we propose a robotic arm error modeling approach to be used along with the simulated datasets for generating a realistic response. The tests on simulated data are performed in both ideal cases and with pseudo-realistic robotic arm pose and visual noise. Our methods show significant improvement and robustness on many metrics in various scenarios compared to state-of-the-art methods.

Published: June 2019

The effects of a multi-ingredient performance supplement (MIPS) incorporating a mixture of branched chain amino acids, beta-alanine, glutamine, creatine, and piperine on resistance training (RT)-induced adaptations remains unclear. Therefore, the purpose of this study was to investigate the effects of this investigational MIPS during six weeks of RT on performance and body composition. Thirty recreationally trained males and females were recruited for this pair-matched, double-blind, placebo-controlled investigation. Subjects were assigned to consume either an experimental MIPS (MIPS) (n = 15) or a placebo (PLA) (n = 15) concurrently with a six-week periodized RT program. Body composition, one-repetition maximum (1RM), and muscular power were assessed at pre- and post-training. Weekly relative volume load was compared between groups. The MIPS and PLA groups demonstrated a significant increase in total body mass (MIPS = +2.9 ± 1.3%; PLA = +2.5 ± 1.7%) and lean mass (MIPS = +5.0 ± 2.1%; PLA = +3.1 ± 1.9%) (p < 0.001) with no changes in fat mass. There were no group × time interactions for any of the body composition measures. Both groups demonstrated similar improvements in maximum strength for the back squat, bench press, and deadlift as well as lower body power from pre- to post-training (p < 0.001). Within the limitations of the current investigation, results failed to demonstrate the benefits of the experimental MIPS for muscular strength and body composition across six weeks of RT compared to PLA.
An Integrated Approach for Modeling Ontology-Based Task Knowledge on an Incident Command System
Authors: Fang Kwoting , Lin Shuoche
Published: June 2019

This paper presents the TTIPP methodology, an integration of task analysis, task ontology, integration definition function modeling (IDEF0), Petri net, and Petri net mark language (PNML), to organize and model the task knowledge in the form of natural language expressions acquired during the knowledge-acquisition process. The goal of the methodology is to make the tasks more useful, accessible, and sharable through the web for a variety of stakeholders interested in solving a problem which is expressed mostly in linguistic form, and to shed light on the nature of problem-solving knowledge. This study provides a core epistemology for the knowledge engineer while developing the task ontology for a generic task. The proposed model overcomes the drawbacks of IDEF0, which are its static nature and Petri net which has no concept of hierarchy. A good number of countries lie on the typhoon and earthquake belts, which make them vulnerable to natural calamities. However, a practical incident command system (ICS) that provides a common framework to allow emergency responders of different backgrounds to work together effectively for standardized, on-the-scene, incident management has yet to be developed. There is a strong need to explicitly share, copy, and reuse the existing problem-solving knowledge in a complex ICS. As an example, the TTIPP model is applied to the task of emergency response for debris-flow during a typhoon as a part of an ICS.
General Overview of Art Music in Kosovo: Social and Political Impact
Authors: KRYEZIU BREZNICA Rreze
Published: June 2019

Art Music, if understood in the sense of concert activity and foundation of professional institutions in Kosovo, started to develop by the middle of the 20th century, i.e. still during the Yugoslav period. Precisely, the population of Albanian ethnos in Kosovo was to share its fate with other people of the ex-Yugoslav State after World War II, from 1945. As an integral part of this development, new economic, political, social, and cultural circumstances arose for the professional development of Art Music as a significant segment of cultural life during this period. Prior to this period, there were no professional music institutions, no artists, composers, instrumentalists, or educated singers in Kosovo.

In order to properly understand the characteristics of Art Music in Kosovo, it is necessary to take a brief look at the impact of social and political circumstances on such development. This article strives to help identify specific problems that initially affected the delayed appearance of such a tradition in Kosovo. Despite all the difficulties, and political-historical circumstances, which had overwhelmed Kosovo, and continue having a huge impact even today (2017-18), Art Music (brought and dealt with very late), has managed to achieve a lot. At least it overcame the dark period and unfavourable conditions it had encountered for centuries.
“Sung Poetry” of the South Siberian Turks: Interrelations between Music and Poetry
Authors: SYCHENKO Galina
Published: June 2019

The article is devoted to the so-called ‘sung
poetry’ of several Turkic-speaking peoples of South Siberia. The author’s main
focus is on the problem of metric organization of poetic and musical parameters
and the interrelations between them. The author starts with a discussion of some
methodological issues, in particular, what can be regarded as ‘meter’ in vocal
folk music. Contrary to some authors, who attribute this term exclusively to
poetic expression, in this article it is understood in a broader sense: as a
system of temporal organization. In Altai, Tuva, Shor, and Khakass song
traditions, there is a ‘syllabic rhythmical formula’ (SRF), which corresponds
to the verses, as well as to the melodic line. The SRF, following the author’s
opinion, can be regarded as a meter for a song, or the song as genre. It
usually regulates number and quality of musical units in correspondence with
the syllables.

This common and rather simple picture, nevertheless, becomes
more complicated when the author starts to describe some particular cases. The
traditions of the Telengits, Chalkans and Kumandins, Shors, and
Khakasses-Sagays are chosen to demonstrate a variety of arrangements of the of
‘sung poetry’ of the South Siberian Turks.

Bu araştırmada, çocukların okula hazır olmalarında önemli etkisi bulunan okuma yazmaya hazırlık ve matematik becerilerinin evde ailesi tarafından ne düzeyde desteklendiği incelenmiştir. Bununla beraber, çocuğa ilişkin çeşitli özelliklerin (yaş, cinsiyet, okul öncesi eğitim alma durumu, okul öncesi eğitim alma süresi) evde sunulan destek üzerindeki etkisi araştırılmıştır. Araştırma, betimsel tarama modelindedir. Araştırmanın örneklemini, Türkiye’nin en büyük ili olan İstanbul ve küçük bir Anadolu şehri olan Aksaray’da okul öncesi eğitim kurumuna devam eden 110 çocuk oluşturmuştur. Ailelerin okuma yazmaya hazırlık ve matematik becerilerini evde orta düzeyde desteklediği belirlenmiştir. Ailelerin çocukların okuma yazmaya hazırlık ve matematik becerilerini destekleme düzeylerinin çocuğun cinsiyetine, yaşına ve doğum sırasına göre farklılık göstermediği belirlenmiştir. Okul öncesi eğitimi alma durumu ve okul öncesi eğitimi alma süresi ise çocukların evde gerçekleştirdikleri yapılandırılmış etkinlikler üzerinde etkili olmuştur. Çocukların okuma yazmaya hazırlık becerilerinin evde desteklenme durumu ile matematik becerilerinin evde desteklenme durumu arasında anlamlı bir ilişki olduğu görülmüştür.

Investigation about nanocarriers has been a hot issue and nanofabrication method still plays an important role. In this work, a phenomenon that reacting linear polystyrene chains can collapse when a reaction media changed from tetrahydrofuran to water was utilized as templates to prepare nanospheres. Free radicals on the surface of the collapsed templates can initiate hydrophilic monomers N-isopropylacrylamide and N,N’-methylenebisacrylamide in water. Effect levels of some factors including stirring rate, N-isopropylacrylamide concentration and reaction time of styrene on size and monodispersity of the spheres were investigated. The results show the obtained spheres had polystyrene cores and crosslinked poly(N-isopropylacrylamide) shells. Monodispersed nanospheres with mean diameter 63nm can be obtained under optimized condition. The results also display that the first effect factor was the reaction time of styrene, and the second was the stirring rate. The proposed technology provides a mode to prepare monodisperse nanospheres or nanocapsules, which are highly attractive for targeting hydrophobic-drug delivery systems, oil-water separation, single molecule detect, colloid science and so on.
Linguistique du locuteur, linguistique de la complexité, linguistique générale : l’apport du français d’Afrique à la linguistique « tout court »
Authors: Ploog Katja
Published: June 2019

La transformation de l’objet français en Afrique au cours des cinquante dernières années va de pair avec la mutation des disciplines affines à la sociolinguistique. Les études étaient alors orientées sur l’interférence des langues maternelles sur le français chez les locuteurs africains et fondées sur des relevés « à la volée » ; plus récemment, le focus s’est porté sur les pratiques sociales liées aux langues, en milieu urbain en particulier. La contribution argumente que le français en Afrique est une chance pour les recherches sur le français parlé et pour l’étude des langues en interaction en général. Le défi majeur de sa constitution en objet d’étude linguistique consistera à développer une méthodologie inspirée de la linguistique de corpus et soucieuse des caractéristiques intrinsèques des données. Celles-ci sont orales pour les plus originales parmi elles, liées au temps et à l’activité d’élaboration discursive du locuteur.
Télépression au travail, relation entre l’utilisation de la messagerie électronique au travail et les échanges leader-membres : rôles de la reconnaissance et de la charge de travail

Published: June 2019

La messagerie électronique (ME) au travail est l’outil de communication le plus utilisé au sein des entreprises actuelles. Cette étude exploratoire tente de comprendre la relation entre l’utilisation perçue de la messagerie électronique et la qualité des relations leader-membres, d’une part, et la télépression, d’autre part, en testant les effets médiateurs de la reconnaissance et de la charge de travail. Les résultats auprès de 56 salariés juniors indiquent que l’utilisation de la messagerie électronique est liée positivement à la qualité des échanges leader-membres et négativement à la télépression. Les effets de l’utilisation perçue de la messagerie électronique sur les échanges entre leader et membres sont médiatisés par la reconnaissance. Les effets de l’utilisation perçue de la ME sur la télépression sont médiatisés par la charge de travail. La présente étude expose ces relations complexes et équivoques, tout en apportant de nouvelles pistes de recherches.
The Relationship Between Pain and Physical Function: Mediating Role of Sleep Quality, Depression, and Fatigue
Authors: Lee Myung Kyung , Oh Ji Hyun
Published: June 2019

The current study investigated whether osteoarthritis pain was associated with physical function and aimed to identify possible multistep indirect pathways of the association between pain and physical function through sleep quality, depression, and fatigue. Using the survey method, data were collected from 222 adults age ≥65 years diagnosed with osteoarthritis at a senior welfare center in Daejeon, Korea. Data were statistically analyzed using serial multiple mediation analysis. Study findings showed that the relationship between pain and limitation of physical function was partially mediated by sleep quality, depression, and fatigue. The experience of pain among older adults with osteoarthritis directly and most strongly led to limitations in physical functioning, and pain-induced sleep disorders, depression, and fatigue may sequentially negatively affect physical functioning. Thus, pain is a possible fundamental cause of poor, or deterioration in, physical functioning in older adults with osteoarthritis. Therefore, pain assessment and pain management should be prioritized when caring for older adults with osteoarthritis. [

Published: June 2019

A data set of 438 calcium transient signals measured from induced pluripotent stem cell derived cardiomyocytes was collected to analyze and separate abnormal signals corresponding to aberrant cardiomyocytes from normal signals corresponding to normally developed cells. After the calcium transient peak detection, the authors computed peak variable values. Each signal peak was determined to be either normal or abnormal. The peak variables were used for machine learning algorithms to classify entire calcium transient signals into normal or abnormal types. The authors evaluated the classification power of 10 variables to separate normal signals from abnormal ones. This article obtained classification accuracies of up to 85-95%, around 5% better than the results in the preliminary research. The correctness of the classification of the signals was inferred either by a biotechnology expert or by an algorithm. The new results are promising for the continuity of this area of study in identifying aberrant calcium transients.
Mitigation of Linear Accelerations and Shear Forces During Drop Head Simulated Falls

Published: June 2019

The danger and risk associated with ice hockey has led to the development of new helmet technologies and testing protocols to minimize the risk of traumatic brain injuries or concussions. Researchers believe that understanding helmet performance across different impact locations and angles during head collisions helps inform helmet manufacturers in the development of helmet testing protocols for brain injury prevention. Based on these beliefs and concerns, this study examined the dynamic interaction of neck compliance, helmet location, and angle of impact in mitigating linear acceleration and shear forces. The results support the hypothesis that an increasing angle of impact decreases peak linear acceleration and increases shear force. Decreasing neck compliance, however, decreases peak linear acceleration and shear force for some helmet impact locations but not all of them. These results add to the literature by implementing a new helmet testing protocol to provide information beyond traditional measures of peak linear acceleration used in current helmet testing standards.
RIPERCORRENDO ALCUNI "PASSI" SULLA STRADA DELLA COSTITUZIONE REPUBBLICANA ITALIANA
Authors: Illari Silvia
Published: June 2019

Ripercorrendo alcuni "passi" del percorso compiuto dalla Costituzione italiana del 1948, si è tentato in primis di soffermare l'attenzione sul modello liberaldemocratico scaturito dall'arduo lavoro dei Costituenti. Questi gettarono le basi di un nuovo inizio, poi seguì la travagliata attuazione e il crescente susseguirsi di progetti di riforma, spesso non arrivati a compimento, se non addirittura respinti con voto popolare. "Tutti avvertono che non va, ma non si sa come corregerla o sostituirla" affermò Ugo Spirito già nel lontano 1972. E intanto la Costituzione del 1948 appare ancora oggi come il patto che lega il popolo italiano nella libertà e nella democrazia, oltre tutte le ragioni di divisione.
