Opis:: An advanced, solvent-less resin based Combustible Cartridge Case (CCC), designed to resolve the inherent problems of shrinkage and limited mechanical strength associated with the gelatinisation of nitrocellulose, has already been developed. The felt-moulded components contain thermoplastic polyvinyl acetate (PVAc) resin as the binder and the enhanced mechanical strength is achieved by carrying out hot compaction of dry felts at an elevated temperature (105 ± 2 °C). Presently, resin based technology is adopted for tank gun ammunition and also for the developed modular CCCs, i.e. the Modular Combustible Case (MCC) for different types of artillery gun ammunition. However, during exhaustive trials conducted with the resin based CCCs in 120 mm tank gun ammunition at three temperatures, i.e. -10, 27 and 55 °C, severe geometrical deformation was noticed when the rounds were conditioned at 55 °C for 24 h., adversely affecting the loading of rounds into the gun chamber. This was attributed to the combined effects of softening of the resin at that temperature and the load of the projectile/ shell (14.4 kg) experienced by the CCC region during conditioning of the round in the horizontal mode. In order to resolve this problem of deformation, PVAc resin was required to be modified. The PVAc resin was modified to the form of a nanocomposite. PVAc nano composite was prepared by dispersing organically modified nano clay, i.e. Cloisite 30B, into the resin before making the CCCs. The nanocomposite of PVAc resin was characterized by FTIR, DMA, softening point measurement etc. The results showed a remarkable improvement in the glass transition temperature (Tg) and in the softening temperature of the modified PVAc resin. This modified PVAc resin was used to prepare CCCs. Furthermore, these CCCs were coated with hexamethylene diisocyanate (HMDI) on the inner and the outer surfaces. The isocyanate coating becomes crosslinked in the matrix, thereby improving the softening point as well as the mechanical properties of the CCCs. These modified CCCs were repeatedly tested at 55 and 60 °C for 24 h. After testing, it was found that no deformation had taken place and the assembled rounds were easily loaded into the gun chamber. The use of the PVAc nanocomposite in the preparation of resin based CCCs, followed by isocyanate coating, is an effective means of achieving the required improvement in structural integrity of the resin CCCs at elevated temperatures.

Opis:: W artykule opisano przypadek, w którym ekspert na podstawie śladów pozostawionych na miejscu zdarzenia w postaci łusek i pocisków nieprawidłowo wytypował model broni, z której zastrzelono trzy osoby. Nieprawidłowy wynik badań eksperta miał wpływ na dalszą pracę służb dochodzeniowo-śledczych. Dopiero skonfrontowanie zeznań świadka z materiałami dowodowymi zabezpieczonymi na miejscu zabójstwa (łuski, pociski) doprowadziło do prawidłowego określenia rodzaju i modelu broni użytej na miejscu zdarzenia. Aby uzyskiwać dokładne wyniki badań, należy analizować szczegółowo wszystkie nawet najdrobniejsze ślady pozostawione na zabezpieczonych dowodach rzeczowych w postaci łusek i pocisków, a także poszczególnych elementach składowych broni. Artykuł obrazuje jak duże znaczenie w procesie wykrywczym mają zeznania świadków, dlatego wskazane jest, by były one udostępniane także ekspertom przeprowadzającym badania z zakresu broni i balistyki. Przedstawiony w artykule przypadek nieprawidłowego wytypowania modelu broni na podstawie przeprowadzonych badań łusek i pocisków nie miałby miejsca, gdyby ekspert dysponował aktami.
The paper presents the case where the expert made a mistake in typing a model of a weapon basing on evidence left on shooting incident scene and comprising of cartridge cases and bullets. Incorrect expert findings had impact on further investigation. The witness testimony combined with crime scene exhibits led to a correct determination of type and model of firearm used to commit homicide. In order to obtain accurate examination findings, the expert needs to analyse precisely each, even the slightest, mark left on exhibit, as well as the ones left on weapon components. The paper demonstrates the significance of witness testimony in the detection process and hence it has been recommended that these testimonies should be rendered available also to the firearms and ballistics examiners. The present case of mistyping a model of weapon would not have occurred if expert had had an insight into casefile.

Tytuł:: Methods of implementation and operation of hardware DRM protection on the example of printer cartridges

Opis:: Tens of millions of printers are sold each year, including copiers and multifunction devices. Each printer needs an ink or toner cartridge, depending on the type of printer. This is where the problems arise that anyone who owns such a device has encountered – the price and availability of cartridges. A set of original cartridges for the printer we bought can sometimes cost more than the printer itself. On the other hand, it is not always possible to buy cheaper replacement consumables. This is often due to the fact that the manufacturer of the printer has implemented a Digital Rights Management (DRM) protection in the chip connected to the cartridge. Bypassing such protection is not trivial, and when a way to do so is learned, it is not disclosed because of the commercial value of such knowledge. The goal of this paper is to determine if it is possible to find out for ourselves how selected DRM protections work by using reverse engineering, and to develop a way to reset these protections so that we are not tied to the price and availability of consumables on the market, as we can remanufacture our cartridges ourselves, which is especially important in the context of the Right to Repair.

Opis:: Bath gray water organoleptically did not appear to be significantly contaminated liquid. However, in order to re-use them, they need proper treatment. When recirculated in a household, they cannot pose a threat to human life. Based on their appearance, it seems that the solution to the problem is the use of cartridges filter. The article presents the results of the filtration of gray water from the bath through the filtration system with a housing double stage polypropylene-carbon filter FCCA-STO and to determine the impact of individual filter layers on wastewater treatment, tests were carried out on a single polypropylene FCPS10 and carbon FCCA filtration cartridge. The aim of the study was to determine the suitability of the selected housing filter cartridges for the treatment of bathing gray water for their reuse. For the tests were used natural bathing gray water from a two-family building inhabited by seven people. Wastewater were fed to the filter with a constant flow rate of 0.1 dm3·s–1. The assessment of the work of the filters based on parameters such as: COD, BOD5, suspension, dry residue, decay and turbidity. The conducted tests have shown a slight improvement in most of the quality parameters of gray water after filtration through selected housing cartridge filters. Only for turbidity, the reduction in the value of the pollution indicator was noticeable. The cartridge filters used in tests, acted like ordinary mechanical filtration cartridges. For the considered gray water, the use of analyzed cartridge filters can only be used for their initial purification.

Opis:: Water is one of the humans’ basic needs that are essential in daily lives. The water use related to the production of the food processing industry must at least meet the quality standards required for drinking water. The Production process water is obtained from the artesian well that has been treated with a physical treatment process. The microbiological examination result of total Coliform is 8.6 MPN/100 ml meaning that it does not meet the quality standard requirements, which is 0 MPN/100 ml (The Minister of Health Regulation Number 492 of 2010, concerning Drinking Water Quality Requirements), it is necessary to treat the production process water using a Melt Blown Filter (MBF) and UV-C rays. The purpose of this study was to determine the differences in the variation of the 1, 3, and 5-micron of Melt Blown Filter cartridge 10” in reducing the amount of total Coliform, as well as the water hardness and their effect on disinfection using UV-C rays. The type of research used is experimental research with a pretest-posttest without control research design. There is a reduction in the average total Coliform after the treatment using a Melt Blown Filter, with a result of 1, 3, and 5-micron as 2.95 MPN /100ml, 3.61 MPB/100 ml, and 7.31 MPN/100 ml with a percentage reduction of 100%, 94.5%, and 82.4%, respectively. The average total Coliform using the Melt Blown Filter equipped with the UV-C rays treatment resulted in a reduction of 1, 3, and 5-micron as 2.95 MPN/100 ml, 3.95 MPN/100 ml, 8.88 MPN/100 ml respectively, with a reduction percentage of 100%, for each treatment. The data analysis for total coliform using the One-Way ANOVA test resulted in a pvalue of 0.001, the effective variation obtained is 1-micron MBF equipped with UV-C rays. The analysis of results pertaining to the water hardness data showed that the use of Melt Blown Filter could not reduce water hardness, but the UV-C rays could still be used accordingly. The data analysis for water hardness was performed using KruskalWallis with a p-value of 0.820, meaning that there are no differences in Melt Blown Filter variation on the results of total water hardness value.

Opis:: Thermal and economic conditions that have to be satisfied by heat exchangers in heat and power generation cause that analysis of the influence of the working medium flowing in heating cartridge pipes is essential for designers. It follows from the state of the heating cartridge after its many-year operation. Because of strength issues that affect design and thermal solutions, it is important to evaluate the influence of heat exchanger working conditions on the possibility of its stability loss. One of the most important elements of heat exchangers are perforated bottoms – perforated plates of significant thickness in which heating cartridge pipes are mounted. For designers of heat exchangers, the definition of loading and analysis of all possible types of failure is of special importance. The paper is a continuation of the conducted investigations on heat exchangers where the calculations of elastic stability of perforated bottoms with pipes inside were developed for inelastic regions.
Warunki cieplne i ekonomiczne stawiane wymiennikom ciepła stosowanym w energetyce powodują, że dla konstruktorów istotna jest analiza wpływu przepływającego czynnika w rurkach wkładu grzewczego. Świadczy o tym stan wkładu grzewczego po wieloletniej pracy urządzenia. Ze względów wytrzymałościowych rzutujących na rozwiązania konstrukcyjne i energetyczne, istotna jest ocena wpływu warunków pracy urządzenia na możliwość utraty jego stateczności.
