Bioaktivni sastojci kozjeg mlijeka

A well balanced diet of modern population includes an increased consumption of products from goat’s milk, which has composition different from the commonly used cow milk. Goat’s milk is characterized by better digestibility, higher buffer capacity than cow’s milk and a lower content of αs1-casein which is responsible for causing allergic reactions. Goat’s milk also contains more free amino acids than cow’s milk. The advantage of goat’s milk is its approximately 30 % higher magnesium content, high selenium content and glutathione peroxidase enzyme, which means that goat’s milk has greater antioxidant properties than cow’s milk.Uravnotežena prehrana suvremenih potrošača sve češće podrazumijeva i povećanu konzumaciju proizvoda od kozjeg mlijeka koje se svojim sastavom znatno razlikuje od kravljeg. Kozje mlijeko karakteriziraju bolja probavljivost, veći puferski kapacitet u odnosu na kravlje mlijeko te niži udjel αs1-kazeina kojeg se smatra odgovornim za brojne alergijske reakcije. Osim toga, kozje mlijeko u usporedbi s kravljim sadrži i znatno veće količine slobodnih aminokiselina. Neke od ostalih prednosti kozjeg mlijeka nad kravljim su oko 30 % više magnezija, visoke koncentracije selena i enzima glutation-peroksidaze koji pridonose većem antioksidacijskom kapacitetu

Zawał komory prawej w praktyce ratownika medycznego

Choroby układu krążenia a w szczególności ostre zespoły wieńcowe są bezpośrednimi stanami zagrożenia życia, z którymi Ratownicy będą spotykali się na co dzień. Złożoność przypadku zawału komory prawej nierzadko stanowi problem zarówno w diagnostyce jak i leczeniu. Praca ta przedstawia istotę zawału, jego rozpoznanie, etapy ewolucji, działania ratownicze jak i stosowaną farmakoterapię.Cardiovascular diseases, in particular acute coronary syndromes, are a direct threat to life with which rescuers will meet on a daily basis. The complexity of the case of right ventricular infarction is often a problem in both diagnosis and treatment. This work presents the essence of the infarction, its diagnosis, stages of evolution, rescue operations, as well as applied pharmacotherapy

Wikis and Wikipedia as a Teaching Tool

Abstract Wikis are a very versatile and easy-to-use tool that is finding increasing applications in teaching and learning. This paper will illustrate how teaching academics can join the wiki revolution. First. it will introduce the common wikis and then focus on Wikipedia, The Free Encyclopedia, which has become one of the most popular Internet sites and offers unique opportunities for teachers and learners. It will describe how wikis and Wikipedia are used as a teaching tool and how to develop them further. Wikipedia can be used for various assignments: for example, students can be asked to reference an unreferenced article or create a completely new one. In doing so, students will see that writing an article is not a 'tedious assignment' but an activity that millions do 'for fun'. By submitting their work to Wikipedia students will see their work benefiting -and being improved upon -by the entire world

Vibration effect on the anthropo-technical systems reliability

Man operates many different types of technical objects (one of which are motor vehicles). In most cases, these are anthropo-technical systems (A-T S) taking into account the essential components of the process of exploitation: man – the operator, the technical object – hardware and software, and the environment - external and internal. One of the important features of exploitation is reliability. It is specified method for assessing the reliability of the system A-T S. Many factors determine reliability. Selecting necessary to take into account factors was possible after analyzing literature and environmental monitoring and a set of representative factors make the man (behavior), the system (ready to use) and threats (vibration, sun, water, etc.). Given the above, indicators have been developed (probability) for the identification of system reliability. In the next planned to use these indicators in the research of the real environmental conditions. The authors engaged in this topic, because in the literature found no studies which take into account so many variables

Dynamic model of a harmonic drive in a toothed gear transmission system

The present paper discusses certain aspects of dynamic modeling of the harmonic drive. In particular, a new original dynamic model of a harmonic drive has been proposed for a power transmission system. The model takes account of nonlinear changes in stiffness, as well as damping. The proposed model of a harmonic drive in the power transmission system is investigated in the Matlab-Simulink environment. Utilization of the identified, developed dynamic model will allow to expand the knowledge about torsional vibration which are present in power transmission systems equipped with harmonic drive as well as it will contribute to a reduction of expenses connected with performing costly experimental tests

Modern trends in diagnostics of technical condition of material handling equipment drives

This study presents problems of material handling equipment drives as objects of vibration diagnostics, as well as the concept of sensors integrated with a surface exposed to damage on an example of a DiaForce sensor integrated with the surface of the inner race of a rolling bearing according to the solution proposed by Fraunhofer Institute in Braunschweig

Influence of housing ribbing modification on frequencies and shapes of vibration

In article an experimental and theoretical modal analysis of selected structural solutions of housings gear was carried out. Results of the examinations enabled to determine a rate of FEM modal parameters conformity with parameters of actual objects by determination of MAC ratio value. Basing on obtained results of the experimental modal analysis, the numerical models of housings were fine tuned. The obtained conformity of the results of experimental and theoretical modal analysis of examined housings solutions enabled to ascertain the correctness of prepared FEM models. The executed modal analysis of various housing versions enabled to estimate influence of made ribbing modifications on form and frequency of its own vibrations

Determination of the damping characteristics of hydro pneumatic suspension strut

The paper presents the results of the hydropneumatic suspension strut researches on indicator test stand. The front hydropneumatic suspension strut for Citroen BX and C5 was researched. The aim of this investigation was to determine the damping characteristics (points of force for maximum linear velocity). The stroke and rotary velocities were selected on indicator test stand. For that extortion parameters force versus displacement and force versus velocity diagrams were determined. The damping characteristics were determined too

Assessment of diagnostic usefulness of vibration of the common rail system in the diesel engine

The paper presents an assessment of diagnostic usefulness of the vibration measurements and analysis of selected components of the common rail system in the diesel engine. Measurements were performed of the selected components of the CR system and changes were determined in the time and frequency structure of the recorded vibration signals. The research has shown that vibration recorded on the injector's housing and the rail of the common rail system is useful diagnostic information for the evaluation of the technical condition of the fuel supply system of a compression ignition engine
