There is very little reliable information about the forces needed to cause injury to the human body. Namely, it is very difficult to obtain reliable reports about the influence of mechanical forces ...and the subjective reaction to these forces, mainly due to the complexity and diversity of the human body in both physical and behavioral aspects.The need for the study of physical, physiological and psychological reactions of living beings in a laboratory, under controlled conditions, has led to the development and use of specialized devices for the simulation of impact and vibrations in order to carry out experiments on humans and animals. "Anthropometric" or "anthropomorphic" dummies that simulate the basic static and dynamic properties of the human body are widely used in the study of plane and car crashes. Thus, for example, a Hybrid III dummy is used in case of a frontal crash of the car. Various research works about automotive and aviation accidents as well as experiments with both dummies and living beings show that full support to the body and limiting the movement of the limbs provide maximum protection from the forces of acceleration. / На сегодняшний день имеется недостаточно достоверной информации о силах, которые приводят к различным травмам пассажиров. В частности, трудно получить достоверные данные о влиянии механических сил и о субъективной реакции на эти силы, в основном из-за широкого разнообразия человеческого организма, как в физическом смысле, так и в отношении их реакции. Необходимость лабораторного изучения физических, физиологических и психологических реакций живых существ в контролируемых условиях способствовала развитию и применению широкого спектра специализированнных устройств для моделирования ударов, столкновений и вибраций, используемых в экспериментах на людях и животных. Антропометрические или антропоморфные манекены, имитирующие основные статические и динамические качества человеческого тела, широко используются в исследованиях авиационных и автомобильных аварий. Так, например, гибридный манекен, Hybrid III dummy, употребляют в случае лобового столкновения автомобилей. Разнообразные исследования автомобильных и авиационных аварий, а также опыты с манекенами и живыми существами показывают, что устойчивое фиксированное положение тела и ограничение подвижности конечностей обеспечивают максимальную защиту от силы разгона и дают большие шансы на выживание. / O silama koje su potrebne da izazovu povrede na ljudskom telu postoji vrlo malo pouzdanih informacija. Naime, veoma je teško doći do pouzdanih podataka o uticaju mehaničkih sila i o subjektivnoj reakciji na ove sile, uglavnom zbog kompleksnosti i raznolikosti ljudskog tela, kako u fizičkom smislu, tako i u pogledu ponašanja. Potreba za proučavanjem fizičkih, fizioloških i psiholoških reakcija živih bića u laboratoriji, pod kontrolisanim uslovima, dovela je do razvoja i upotrebe širokog spektra specijalizovanih uređaja za simulaciju udara i vibracija za eksperimente na ljudima i životinjama. 'Antropometričke' ili 'antropomorfne' lutke, koje simuliraju osnovne statičke i dinamičke osobine ljudskog tela, uveliko se koriste u istraživanju avionskih i automobilskih nesreća. Tako, na primer, hibridna lutka, Hybrid III dummy, koristi se u slučaju čeonog automobilskog sudara. Razna istraživanja automobilskih i vazduhoplovnih nezgoda, kao i eksperimenti sa lutkama i živim bićima, pokazuju da potpuna potpora tela i ograničenje kretanja ekstremiteta obezbeđuju maksimalnu zaštitu od sila ubrzanja.
This book details results from the human genome project and presents the crossover to the human metagenome/microbiome. It brings a new perspective by combining information gained from the human ...genome with that derived from parallel metagenomic studies.
Recently, omega-3 fatty acids are in the center of attention for their potent anti-inflammatory effects. Osteoporosis as a chronic senile disease is associated with inflammation, and the role of ...inflammatory mediators has been demonstrated in the recent years. The beneficial effects of n-3 fatty acids on bone were proven in many animal studies, while to date, no conclusive data is available in human. The aim of this study was to evaluate the impact of n-3 fatty acids on bone biomarkers in osteoporotic women.
Forty osteoporotic post-menopausal women were recruited in the study and randomized in receiving either 40 g canola oil or the same amount sunflower oil per day as their dietary oil for 3 months. Serum levels of osteocalcin, bone alkaline phosphatase (BALP), N telo peptide collagen (NTX) and 25- hydroxy vitamin D3 were measured at baseline and at the end of the third month in both groups.
In the canola oil group, BALP and NTX were increased after 3 months while Osteocalcin decreased in both groups slightly; however,none of these changes were significant. In both groups, serum vitamin D3 was increased significantly; however, this change between groups was not significant.
Canola oil did not affect bone formation and resorption significantly after 3 months consumption. Further investigations with longer follow up are recommended.
The differences between intrinsic aging and photoaging are reviewed. The various model systems currently employed for the studies of aging and photoaging are discussed. Findings on age associated ...decrements in receptor/ligand mediated signaling as well as changes during cellular senescence in the expression of nuclear transcription factors are described. The role of telomere shortening and oxidative damage in the aging process is explained. At the cellular level, genetic and behavioral differences between aging and photoaging are illustrated with particular emphasis on changes in the structure and function of the tumor suppressor gene pS3.

This article discusses the work of three Goa-based Lusophone writers active under the Estado Novo: Alberto de Menezes Rodrigues, Ananta Rau Sar Dessai and Telo de Mascarenhas. By comparing writings ...composed and published either side of the demise of Portuguese colonial rule in 1961, I map the fissiparous literary field of this little-studied period in Goa. I argue that Menezes Rodrigues displays a regime-compliant quietism before going on to indulge in social fantasy and effect a reinvestment in an identity rooted in the local vernacular, Konkani. Sar Dessai comes closest to a publicly subversive postcolonising intervention before adopting a pan-Indian outlook. Mascarenhas, for his part, exhibits the most complete oppositional stance open to Lusophone Goans but also the linguistic and cultural cost of political integration into India. Taken as a whole, compared to other emergent Lusophone cultures, the Portuguese-language literary scene that existed and subsisted in Goa proves eccentric and ambivalent. Keywords: Goan literature; Portuguese India; Alberto de Menezes Rodrigues; Telo de Mascarenhas; Ananta Rau Sar Dessai
Tekst uvodoma osvetli razmerje med telesom in „dušo“, pravzaprav duševnimi pojavi, saj te metafizične entitete ni niti v objektivnem niti v subjektivnem svetu – za razliko od konkretnega, nenehno ...spreminjajočega se toka zavestnih izkušenj (ki so za posameznika nekaj najbolj realnega, čeprav še vedno ne vemo, kako nastanejo in čemu služijo) –, za nameček pa je tudi ni mogoče utemeljiti ali pojasniti z evolucijsko teorijo. Duša (v svoji enoviti in nesmrtni formi), ki jo Bog podari le človeški „kroni stvarstva“, obstaja samo v religiozni perspektivi in torej kot „zgolj“ intersubjektivna, v kolektivni domišljiji in komunikaciji vzpostavljena in ohranjajoča se realnost, ki ima še vedno vse prej kot zanemarljiv vpliv na precejšnje število ljudi, in to ne le vernikov. Dognanja bioloških ved pa čedalje bolj rušijo tudi vero v obstoj svobodne volje in enega samega, nedeljivega in avtentičnega („resničnega“) jaza (sebstva), ki je v optiki liberalnega humanizma ultimativni vir smisla, ekonomskih odločitev ter estetskih, moralnih in političnih sodb. Osrednji del sestavljajo analize dojemanj človeške duševnosti in njihov vpliv na organizacijo družbenega nadzorstva, izvrševanje oblasti in upravičevanje hierarhij, ki so izvorno praviloma vselej namišljene, sčasoma pa postajajo vse bolj empirično otipljive in okostenele: kot zloslutne prerokbe, ki se uresničujejo same – dokler jih „oni in one spodaj“ (dozdevno manjvredni in običajno zapostavljeni, zatirani, izkoriščani, prezirani ali celo osovraženi subjekti) s političnim bojem ne postavijo pod vprašaj, kar se v zgodovini pripeti pomenljivo redko, zelo počasi in ne vedno uspešno. V zvezi s tem je posebna pozornost namenjena razgrnitvi in preučitvi različnih pomenov čustveno močno otovorjene besede „svoboda“. V sklepnem delu steče beseda o duševni motenosti in normalnosti, in sicer predvsem v povezavi z nasilnim vedenjem in različnimi načini soočanja posameznikov z „vse preveč človeškim“ problemom raznovrstnega trpljenja kot (po vsej verjetnosti neodpravljive) tegobe, ki te ne doleti le zaradi te ali one smole, zle usode ali nesrečne konstelacije zvezd in planetov, ampak že zgolj zato, ker si živ, ker si kot subjekt ujet v življenje – v neuspeh lastnega nerojstva – in z njim spete naravne mehanizme, na katere pa se vse prepogosto prilepi še kup družbeno, kulturno in medosebno generiranega gorja. Najbolj na kratko in karikirano rečeno: človeška eksistenca = duševna motnja. Ta težava se dandanes vse bolj „rešuje“ s kupovanjem komercialnih dobrin in storitev, ki obljubljajo doživljanje prijetnih občutkov (in eo ipso srečnost), in z uživanjem zdravil ali (zakonitih in nezakonitih) drog, ki neposredno spreminjajo posameznikov biokemični sistem. To pa ima več kot otipljive kriminogene učinke, saj je večina kriminalnega vedenja posredno ali neposredno povezana s posameznikovo težnjo po sreči (s hrepenenjem po prijetnih občutkih in netoleranco do neprijetnih občutkov).
Growing Unmanned Aerial Vehicle (UAV) market trends and interest in potential uses such as monitoring, visual inspection, object detection, and path planning have shown promising results using ...machine learning techniques. However, UAV adoption faces several challenges in real-life scenarios as lowaccuracy sensors are involved in the identification, tracking, and localization of UAVs. In order to overcome the aforementioned challenges, this paper proposes an intelligent machine learningbased system coupled with computer vision (CV) to detect objects and localize UAVs equipped with just a monocular camera. The experimental results using the Telo DJI drone demonstrate that the proposed methodology can detect, track objects, and localize the drone with high accuracy. The system's ability for automated monitoring in real environments can lend its uses for urban traffic, logistics, and security applications.
