RFID TECHNNOLOGY - NEW CHALLENGE FOR MANUFACTURING AND LOGISTICS CENTERS

RFID technology can be exploited in newly developed logistics centers in Polandas well. The Radio frequency identification (RFID) has been recognized as one of the greatesttechnologies implemented by enterprises in different branches. Constantly increasing numberof enterprises, which are making use of RFID technology to improve their efficiency ofmanufacturing goods, functioning as well as to achieve a competitive advantage on themarket, shows the great necessity of large changes. One of the fields where RFID can be usedis logistics centers. There are projects that implement RFID into logistics centers. Suchprojects start with a study of what kinds of needs are in the market, and proceeds to thedevelopment of concept as well as project determines what the new systems and hardwarerequirements will be to translate the concept of logistics centers with RFID systems to anactual infrastructure. Conclusion is that RFID will be more universally diffused andassimilated into everyday life in the future.RFID, logistics centre, project

VWP is a manufacturer of passenger cars. Currently, the company manufactures two types of utility cars: the Caddy, which constitutes the basis of production, and the T5 Transporter. The main target group for the products manufactured by the Poznań-based branch of Volkswagen are business clients, who use the utility cars for the transport of lighter goods. About 94% of manufactured vehicles are exported as part of the intra-Community supply of goods, as well as to third countries

Polylactide Used as Filment in 3d Printing – Part 2: TG-DTG, DSC and DRIFT investigations

A series of structural and thermal analysis research (TG-DTG, DSC, DRIFT) were performed for the samples of polylactide (PLA), which is commonly used in additive technologies as a structural material. In total four materials were considered, including two containing dyes with different colors, a material made of PLA recyclate and a graphene-modified PLA material. It was noted that PLA material reinforced with graphene phase (GRAFYLON®) retains the best thermal properties (TG-DTG), which results in wider possibilities of its processing, including further modification and usability in manufacturing vehicle structural elements. Recycled PLA material (ALFA+W) was characterized by a higher melting point (Tp) by more than 20oC than other samples (DSC analysis), so it can be more useful in the production of structural elements operating, as well as used at elevated temperatures

Finansowanie ochrony środowiska a jakość życia mieszkańców Polski i krajów sąsiadujących

The purpose of the article is compare level of financing environmental protection in Poland, Slovakia, Czech Republic and Lithuania in regard to public institutions responsible for city logistics as well as to the enterprises. The environment protection issues is present in many publications especially with the background in logistics as well as social issues, connected with life quality. Financing ecological actions means fulfilling duties coming from the European Union accessing agreement as well as influence on the city inhabitants life quality in Poland. The relevance of the above mentioned issues is the motivation to evaluate one of environmental issues, which is structure and quantity of financial expenditure. Decision about quantity and quality of realized tasks in the research influence od city inhabitants life.Celem artykułu jest porównanie poziomu finansowania ochrony środowiska w Polsce na tle Słowacji, Czech i Litwy, z uwzględnieniem przede wszystkim działalności podmiotów publicznych, odpowiedzialnych za logistykę miasta, i przedsiębiorstw. Temat ochrony środowiska cechuje się wysoką aktualnością, szczególnie na tle zachodzących zmian w logistyce i tych społecznych, związanych z jakością życia. Finansowanie działań proekologicznych oznacza zaangażowanie i  spełnianie obowiązków wynikających z umowy akcesyjnej z Unią Europejską i przede wszystkim wpływa na jakość życia mieszkańców miast w Polsce. Istotność tematyki stanowiła motywację do oceny jednej ze składowych działalności środowiskowych, jaką jest struktura i wysokość nakładów finansowych. Decyzja o liczbie i jakości realizowanych w badanym zakresie zadań wpływa na życie mieszkańców miast

The influence of piroxicam, a non-selective cyclooxygenase inhibitor, on autonomic nervous system activity in experimental cyclophosphamide-induced hemorrhagic cystitis and bladder outlet obstruction in rats

Signs and symptoms of secondary overactive bladder (OAB) are observed both in course of infravesical obstruction of urine outflow in patients with benign prostatic hyperplasia, and as a result of development of hemorrhagic cystitis (HC) following administration of cyclophosphamide (CP). Non-steroidal antiinflammatory drugs (NSAIDs) alleviate symptoms of bladder overactivity reducing local synthesis of prostaglandins (PGs), but precise effects of those agents on functions of the autonomic nervous system (ANS) in course of OAB remain unknown. The purpose of this study was to evaluate the effect of piroxicam-induced prostaglandins (PGs) synthesis block on activity of the ANS in two experimental models of secondary OAB: bladder outlet obstruction (BOO) and cyclophosphamide-induced HC (CP-HC), by heart rate variability analysis (HRV). The experiment was performed on a group of rats with surgically induced 2-week BOO, and on a group of rats that were administered CP five times, with corresponding control groups. Study animals were given piroxicam (PRX) i.p. in two doses: 2 and 10 mg/kg b.w. In the BOO model, PRX in both doses revealed a trend for reduction of value of all non-normalized components of HRV. The lower PRX dose caused an increased nHF value, and PRX administered in the dose of 10 mg/kg b.w. caused an increase of the nLF value. In the CP-HC model, the lower PRX dose caused a trend for an increase of values of all non-normalized components, and the higher dose ñ for their decrease. Both doses of PRX in that model caused increase of the nLF value. Inhibition of PGs synthesis caused changes of ANS function in both models of OAB. Both in BOO and in CP-HC, PGs seem to be ANS-activating factors, responsible for maintenance of a high parasympathetic activity. In both models, inhibition of PGs synthesis with PRX administered at the dose of 10 mg/kg b.w. lead to functional reconstruction of ANS, with marked sympathetic predominance. That may contribute to reduction of the bladder contractile action and improvement of its compliance in the filling period, which was demonstrated by other authors in urodynamic tests for NSAIDs.prostaglandinsautonomic nervous systemheart rate variabilit

The influence of montelukast on the autonomic nervous system activity in rats with cyclophosphamide-induced hemorrhagic cystitis

The complex pathogenesis of cyclophosphamide-induced hemorrhagic cystitis involves arachidonic acid-derived inflammatory mediators, among them leukotrienes. Montelukast, a leukotriene receptor antagonist, is reported to exert an alleviatory effect in the course of cystitis associated with overactive bladder symptoms. The aim of this study was to verify whether the effect of montelukast is also associated with its influence on autonomic activity. The experiment included 20 rats with cyclophosphamide-induced hemorrhagic cystitis (75 mg/kg, four doses every second day), among them, 10 treated with oral montelukast (10 mg/kg for 8 days) and 10 controls. Time and frequency domain analyses of heart rate variability (HRV) were conducted in all the rats as an indirect measure of their autonomic activity. The montelukast-treated animals showed an increase in root mean square of successive differences (rMSSD), as well as an increase in HRV spectrum total power (TP) and power of very low (VLF) spectral component. This suggests that due to its anti-inflammatory and its anti-leukotriene effect, montelukast improves overall autonomic activity, with no preferential influence on either the sympathetic or parasympathetic part. Furthermore, the increase in VLF corresponds to attenuation of inflammatory response. In conclusion, this study showed that aside from its antagonistic effect on leukotriene receptors, montelukast can also modulate autonomic activity
