Karate in MMA Analysis of Lyoto Macida’s Career and Fighting Style

Fighting as a sport represents the phenomenon of civilization which involves refined and legalized fightbetween two people with strict limitations. Although we find roots of MMA in Ancient Greece, officially it is a relativelynew sport, created at the end of the 20th century. It united all well-known martial arts into one system, and this paperreflects on the distinguished representative and “modern ambassador” of karate, Lyoto Machida. Machida had 29official MMA fights in various organizations, and in 2009 he became the world champion at the Ultimate FightingChampionship, the world’s best MMA organization. The importance of winning this championship is great for karateand it lies in the confirmation of the applicability of karate in real fight. The aim of this paper is to describe hissuccessful career in sports and to look into the fighting style which brought him glory

Influence of two-month training program on anthropometry and VO2 max in recreational athletes

The aim was to evaluate the effect of a two-month training program on some anthropometric characteristics and maximum oxygen consumption (VO2 max) in male and female recreational athletes. Study included 62 participants, 30 males and 32 females. All participants were doing recreational sport, aged from 35 to 50 years old. In order to obtain accurate results, the following instruments were used: measuring tape, InnerScan body composition monitor Tanita BC-532, and "Technogym" treadmill where they were performing submaximal aerobic test. Training process lasted for two months and consisted of two testing sessions. The training program has included three sessions per week for about 90 minutes. T-test for paired samples was used in the statistical program "SPSS", and results suggested that there was a positive effect of a two-month training process on certain anthropometric characteristics and the maximal oxygen uptake in both male and female subjects

DETECTION AND HANDLING EXCEPTIONS IN BUSINESS PROCESS MANAGEMENT SYSTEMS USING ACTIVE SEMANTIC MODEL

Although business process management systems (BPM) have been used over the years, their performance in unpredicted situations has not been adequately solved. In these cases, it is common to request user assistance or invoke predefined procedures. In this paper, we propose using the Active Semantic Model (ASM) to detect and handle exceptions. This is a specifically developed semantic network model for modeling of semantic features of the business processes. ASM is capable of classifying new situations based on their similarities with existing ones. Within BPM systems this is then used to classify new situations as exceptions and to handle the exceptions by changing the process based on ASM’s previous experience. This enables automatic detection and handling of exceptions which significantly improves the performance of bpm systems

USER DEFINED GEOMETRIC FEATURE FOR THE CREATION OF THE FEMORAL NECK ENVELOPING SURFACE

There is a growing demand for application of personalized bone implants (endoprostheses or macro-scaffolds, and fixators) which conform the anatomy of patient. Hence the need for a CAD procedure that enables fast and sufficiently accurate digital reconstruction of the traumatized bone geometry. Research presented in this paper addresses digital reconstruction of the femoral neck fracture. The results point out that User-Defined (geometric) Feature (UDF) concept is the most convenient to use in digital reconstruction of numerous variants of the same topology, such as in this kind of bone region. UDF, named FemoNeck, is developed to demonstrate capability of the chosen concept. Its geometry, controlled by a dozen of parameters, can be easily shaped according to anatomy of femoral neck region of the specific patient. That kind of CAD procedure should use minimally required set of geometric (anatomical) parameters, which can be easily captured from X-ray or Computed Tomography (CT) images. For the statistical analysis of geometry and UDF development we used CT scans of proximal femur of 24 Caucasian female and male adults. The validation of the proposed method was done by applying it for remodeling four femoral necks of four different proximal femurs and by comparing the geometrical congruency between the raw polygonal models gained directly from CT scan and reconstructed models

THE INFLUENCE OF VARIOUS MICROENVIRONMENTAL FACTORS ON BIOMECHANICAL FEATURES OF DIFFERENT SUTURE MATERIALS USED IN HEPATO-PANCREATO-BILIARY SURGERY

The key features of any suture material, such as its tensile strength, knot security, resorbability, handling characteristics and biological behavior must be taken into account during the selection process. These biomechanical features may be variable in different microenvironmental conditions in the human body in which the sutures are placed due to the influence of numerous local biohumoral factors. We have reviewed the data on the impact of pancreatic juice and bile, various pH conditions, chemotherapy and heat on different suture materials behavior. It is suggested that in pancreatic and biliary surgery polydioxanone sutures should be used. The review has also demonstrated that absorbable suture materials were more sensitive to pH than non-absorbable sutures. In addition, polyglyconate sutures were the strongest of all absorbable synthetic sutures when exposed to heat and cytotoxic drugs. This review provides a better basis for the selection of suture materials for specific applications

REVIEW OF BONE SCAFFOLD DESIGN CONCEPTS AND DESIGN METHODS

The paper brings out a review of existing, state-of-the-art approaches to designing the geometry of the scaffolds that are used for tissue engineering with a special emphasis on the macro scaffolds aimed for bone tissue recovery. Similar concepts of different authors are organized into groups. The focus of the paper is on determining the existing concepts as well as their advantages and disadvantages. Besides the review of scaffolds' geometry solutions, the analysis of the existing designs points to some serious misconceptions regarding the scaffold role within the (bone) tissue recovery. In the last section of the paper, the main requirements regarding geometry, that is, architecture and corresponding mechanical properties and permeability are reconsidered

Miliaria Scarlatinosa, A Peculiar and Rare Form of Scarlet Fever – A Case Repor

Scarlet fever typically presents with distinctive erythematous papular rash following pharyngitis. Atypical forms may develop, making the diagnosis difficult. We present the case of a girl with feve, and unusual vesicular skin eruption (miliaria scarlatinosa) preceded by a skin infection, without mucosal changes. Leukocyte count, C-reactive protein, and antistreptolysin O-titer were elevated. Bacteriological swabs of the skin injury revealed Streptococcus pyogenes. Histopathology was compatible with scarlet fever exanthema. Intramuscular penicillin and topical wound care induced complete remission. It is of great importance to be aware of uncommon clinical presentations of scarlet fever in order to establish a timely diagnosis and prevent potential complications

Tyre Design and Optimization by Dedicated CAD Tyre Model

Structural optimization by Finite Elements (FE) is proved very effective in tyre design. For that purpose, major tyre manufacturers use in-house applications. An alternative solution, involving dedicated CAD tyre model (DCTM), is here proposed. DCTM concept permits to easily change the FE tyre models, concerning shape and structure, by moving a part of pre-processing from FE analysis to CAD. No special skills regarding CAD or FEA are required. For every new tyre design, only a new DCTM and a corresponding FE model must be built. All subsequent model changes are automatically performed by mapping and translation routines. To test this concept, DTCM models of an existing tyre were created and used within a pilot design study

Merenje protoka pomoću mernih blendi - poređenje rezultata proračuna protoka prema standardima ISO 5167:1989 i ISO 5167:2007

Merenje protoka fluida je jedno od osnovnih merenja koje se obavlja u procesnoj tehnici, termotehnici, energetici i mnogim drugim oblastima tehnike. Zavisno od potreba potrebno je odabrati odgovarajući metod, kojim može da se sprovede merenje na najjednostavniji način, uz dovoljnu tačnost, i uz najmanje ometanje tehnološkog postupka. Merenje protoka pomoću mernih blendi se svodi na ugradnju merne blende u cevovod kružnog preseka i posredno utvrđivanje protoka merenjem razlike pritisaka ispred i iza blende. Ovaj metod je veoma čest u industrijskoj praksi, jer je normiran kroz standarde kao što su npr. SRPS EN ISO 5167:2012 „Merenje protoka fluida pomoću uređaja sa diferencijalnim pritiskom ugrađenih u cevovode kružnog poprečnog preseka - Deo 1: Opšti principi i zahtevi“ koji je identičan sa EN ISO 5167-1:2003 ili ASME MFC-14M-2001 „Measurement of fluid flow using small bore precision orifice meters”. Proračunska procedura pomoću koje se izračunava protok fluida je u važećem standardu SRPS EN ISO 5167:2012 drugačija nego u prethodnim izdanjima istog standarda 1980., 1989., 1993., kao i iz 1998. Imajući ovo u vidu postavlja se pitanje da li se i za koliko razlikuju izračunati protoci fluida, pa je u ovom radu analizirano nekoliko konkretnih slučajeva. U pitanju su merenja na industrijskim instalacijama, kao i merenja obavljena u Laboratoriji za procesnu tehniku na Mašinskom fakultetu u Beogradu
