    Pure fiber-reinforced polymer composites can give protection only of a certain level of ballistic threat i.e. only of small arms ammunition. For higher ballistic threat of high energy projectiles, ballistic inserts of ceramic tiles/composite back panel are used. Such inserts are usually composed of ceramic tiles, facing the impact, laid on fiberreinforced polymer back panel where the hardness of the ceramic is the main factor contributing to the ballistic strength of the inserts. The purpose of the back panel is to keep the tiles stuck together and to be strong/rigid enough to keep the backface blunt trauma effect of the inserts under the allowed upper limit of 44 mm (1,73 inch). In this study we used pure (99,5%) alumina 5 x 5 x 0,9 cm ceramic tiles and different types of back panel high-performance composites reinforced with aramid (Kevlar), ballistic nylon, ultra-high molecular weight polyetjylene (UHMWPE, Dyneema) and glass fibers. The purpose of the study was to find the optimal back panel construction in terms of its trauma performance, weight and price level. It was shown that the lowest trauma effect could be achieved with aramid composites, the lowest weight with UHMWPE, the cheapest – with glass but with a sacrifice of the weight and ballistic nylon backpanel was somewhere between aramid and glass panels in terms of its weight and price level

    Predicting the ballistic strength of aramid fiber composites by implementing full factorial experimental design

    Get PDF
    The purpose of the study is to predict the ballistic strength of hard aramid fiber/phenolic ballistic composites by implementing the full factorial experimental design. When designing ballistic composites two major factors are the most important: the ballistic strength and the weight of the protection. The ultimate target is to achieve the required ballistic strength with the lowest possible weight of protection. The hard ballistic aramid/phenolic composites were made by open mold high pressure, high-temperature compression of prepreg made of plain woven aramid fibre fabric and polyvinyl butyral modified phenolic resin. The preparation of the composites was done by applying the 22 full factorial experimental design. The areal weight of the composites was taken to be the first factor and the second – fibre/resin ratio. The first factor low and high levels were chosen to be 2 kg/m2 and 9 kg/m2, respectively and for the second factor – 80/20 and 50/50, respectively. The first-order linear model to approximate the response i.e. the ballistic strength of the composites within the study domain (2 – 9) kg/m2 x (80/20 – 50/50) ratio was used. The influence of each individual factor on the response function was established, as well as the interaction of the two factors. It was found out that the estimated first-degree regression equation with interaction gives a very good approximation of the experimental results of the ballistic strength of composites within the study domain. Key words: aramid fibre, ballistic composites, factorial design, regression equation, V

    Effective process for lipid reduction using high speed centrifugation compared with ultracentrifugation

    Introduction: Reducing laboratory errors and improving patient safety is receiving a lot of attention. Lipaemic samples are cause of analytical errors and present challenges for laboratories, particularly for those without ultracentrifuges. Lipaemia can originate from physiological (postprandial metabo-lism), para-physiological causes (e.g. IV administration of lipids) as well as metabolic disturbances (e.g. hypertriglyceridaemia). Materials and methods: We have evaluated a procedure with 10 native lipaemic sample pools (triglyceride concentration range 11.6-42.7 mmol/L) for the ability to reduce lipid concentration using a high speed micro-centrifuge (double centrifuged at 21.885 x g for 15 min) compared with an ultracen-trifuge, and provide accurate results. Results of sodium, creatinine, urate, total protein, lactate dehydrogenase (LD), magnesium and, cholesterol and triglyceride analysis on a Beckman DxC800 analyser are presented. Results: Data from our tertiary level hospital showed ~0.7% of the samples received for lipid studies have triglyceride levels > 10 mmol/L which can potentially cause analytical interference. The mean differences from the neat aliquot to the ultracentrifuged and high speed centrifuged sample pools were: cholesterol 4.9 mmol/L and 3.1 mmol/L; and triglycerides 17.4 mmol/L and 15.0 mmol/L respectively. The data confirms high speed centrifugation is almost as effective as ultracentrifugation in lipid reduction. Conclusion: The procedure utilized in this study using a high speed micro-centrifuge showed it is effective in reducing lipid levels and provides a suitable alternative to ultracentrifuged samples to pro-vide accurate results

    The system analysis is the necessary activity in designing information systems (IS), especially in creating complex IS which have to satisfy a wide pallet of users’ demands. Installing the IS without expert’s planning and leading can lead to the huge users’ dissatisfaction, and maybe non - usage of system which often the consequent system do not work. This is especially emphasized when we talk about web based IS which demand a strong defined access rules as well as accurate data update procedures. In this paper is made a system analysis and design of IS for local economic development (LED). The problem of LED itself is very important because of the decentralization process that happens in R.of Macedonia in recent year as well as the global crises and the necessity of employment increasing. As an important factor we mention a need of increasing the usage of IS, especially when is concern of the issues that help for the young people’s position. Analysis of the need of IS for LED’s support is made on the couple of present local governments’ (LG) web sites in R.of Macedonia as well as the interviews and a questionnaire of the LER’s responsible in the LG and potential users of this kind of information. The results of this survey are decanting in analysis of the information needs as well as the LED’s support System’s proposition. We are using the structural analysis and logical design of IS as the working’ methodology. For this purpose, a series of systematic undertaken processes were used. These processes, we think, that will enhance the information and usage of computer’s IS in function of business climate and business community’s better information. The proposed model for LED’s support IS which have to cover the users’ demands will be made with creating a redundant databases, loaded whit trigger procedures and intelligent agents
