Opis:
A devised methodology presented here allows the determination of di-n-butyl phthalate in environmental samples (water and landfill leachate) using solid-phase extraction (SPE) and gas chromatography. It is developed based on the use of a gas chromatograph with an FID detector. Preliminary testing has also provided extraction parameters and conditions for chromatographic determination, with calibration applied by reference to an internal standard. The linearity of the calibration curve has been tested in DBP concentrations ranging from 0 to 7.5 mg/L, with the data obtained showing that, throughout this range, the detector readings as a function of the DBP concentrations remain linear (R2 coefficient >0.99). The average levels of recovery of DBP from aqueous solutions of phthalates are in the range of 97-109%, while the corresponding figures for leachates are 85-101%. The values of the coefficients of variation associated with the results obtained do not exceed 5%. The results, therefore, indicate that the applied extraction method is effective as regards DBP extraction from both water and landfill leachate, while numerous other substances present in the leachate from landfill sites apparently do not affect the correct determination of di-n-butyl phthalate by the method developed.

Opis:
Wykorzystanie okrzemek jako środowiskowych śladów kryminalistycznych stanowi idealne narzędzie do powiązania osoby z konkretnym miejscem – środowiskiem, a także może być pomocne przy diagnozowaniu utonięć lub przy typowaniu miejsca utonięcia. Narzędzie to jest standardowo stosowane przez organy ścigania w wielu krajach Europy, a także w Australii, Chinach, Indiach oraz Stanach Zjednoczonych Ameryki. Celem niniejszej pracy jest wskazanie możliwych metod i zasad, które powinny być stosowane przy zabezpieczaniu okrzemek na miejscu zdarzenia podczas takich czynności procesowych jak: oględziny i przeszukanie, a także propagowanie wiedzy z zakresu diatomologii kryminalistycznej w Polsce. Niniejsza metodyka została opracowana w oparciu o uznane i powszechnie stosowane doświadczenia w pozyskiwaniu i zabezpieczaniu okrzemek do celów badan z zakresu ich taksonomii i ekologii na podstawie piśmiennictwa. Rekomendujemy procedurę postępowania przy zabezpieczaniu materiału okrzemkowego oparta na metodach stosowanych i wypracowanych przez naukowców oraz dostosowana do warunków i technicznych możliwości, którymi dysponuje polski policjant – technik kryminalistyki.
The use of diatoms as environmental forensic traces is an ideal tool for linking a person to a specific place – environment, and may also be helpful in diagnosing drownings or determining the place of drowning. This is a standard tool used by law enforcement agencies in numerous European countries, as well as in Australia, China, India and the United States of America. The aim of this work is to indicate possible methods and principles that should be used to secure diatoms at the scene during procedural activities such as site examination and search, as well as to promote knowledge in the field of forensic diatomology in Poland. This methodology was developed based on recognized and widely used experience in obtaining and securing diatoms for the purposes of research based on their taxonomy and ecology as well as on the literature. We recommend a procedure for securing diatom material based on methods used and developed by scientists and adapted to the conditions and technical capabilities available to a Polish police officer – a forensic technician.

Opis:
Buffalopox (BPX) is a highly contagious disease that causes high morbidity and production losses in buffaloes. During this study, seroprevalence, effect of various associated risk factors, and pathological studies of BPX were recorded in the Punjab province. A total of 97 blood samples and 63 scabs were collected from clinically pox suspected buffaloes. Serum was harvested to perform single radial hemolysis to assess the seroprevalence, and scabs were subjected to PCR for BPX virus confirmation. Results revealed that, animal demographics and environmental associated factors showed significant effect (p<0.05,1<R2>0) on BPX occurrence. The overall BPX seroprevalence was recorded 4.18% in the Punjab province. The BPX was recorded 5.48% in Nili Ravi breed during winter (7.42%), aged 5-7 years (7.46%) under loose housing (5.51%) in the Faisalabad region (8.03%). Further, BPX was 5.37% in pregnant, 6.86% pregnant milking buffaloes during the 3rd lactation period (7.28%) in dairy herds (5.20%). The BPX was 5.22% in non-vaccinated buffaloes where multiple animals were reared together (4.99%) in the herds having 21-30 total number of animals. A total of 49 scab samples were found positive for the BPX virus via PCR with C18L gene amplification. Grossly, inflammatory lesions with pits in the center and wart-like nodules were seen on teats and udder of buffaloes. Increased leukocytes, especially neutrophils and lymphocytes, were seen in the blood of the infected animals. These results provide a broader window to understand the effect of associated risk factors, strengthen the diagnostic aid, and to contain the current spread of BPX in Pakistan to safeguard large ruminant-based livelihood.

Opis:
Based on a record sample from the Rayleigh model, we consider the problem of estimating the scale and location parameters of the model and predicting the future unobserved record data. Maximum likelihood and Bayesian approaches under different loss functions are used to estimate the model's parameters. The Gibbs sampler and Metropolis-Hastings methods are used within the Bayesian procedures to draw the Markov Chain Monte Carlo (MCMC) samples, used in turn to compute the Bayes estimator and the point predictors of the future record data. Monte Carlo simulations are performed to study the behaviour and to compare methods obtained in this way. Two examples of real data have been analyzed to illustrate the procedures developed here.

Opis:
The results of microstructure examinations and UTS, YS, El, RA carried out on low-carbon cast steel containing 0.15% C. The tests were carried out on specimens cut out from samples cast on a large-size casting and from samples cast in separate foundry moulds. It has been shown that significant differences in grain size observed in the material of the separately cast samples and cast-on samples occur only in the as-cast. In the as-cast state, in materials from different tests, both pearlite percent content in the structure and mean true interlamellar spacing remain unchanged. On the other hand, these parameters undergo significant changes in the materials after heat treatment. The mechanical properties (after normalization) of the cast-on sample of the tested cast steel were slightly inferior to the values obtained for the sample cast in a separate foundry mould. The microscopic examinations of the fracture micro-relief carried out by SEM showed the presence of numerous, small non-metallic inclusions, composed mainly of oxide-sulphides containing Mn, S, Al, Ca and O, occurring individually and in clusters.

This article presents the materials of deformability studies of pre-stressed steel-concrete beams reinforced with a package of reinforcement with different ratio of tape and rebar in the pure bending moment zone. The aim of the research was determination of the reinforcement percentage influence, for pre-stressed reinforced concrete beams reinforced with a package of reinforcement on their deformability. Also, the aim was to evaluate the effectiveness of using pre-stressed rebar in combined reinforcement. The practical significance of the experimental research is to study the deformability in pre-stressed bending elements with external tape and rebar reinforcement, taking into account the influence of different ratios of reinforcement areas within the combined reinforcement and development of proposals for such structures` calculation and design. The scientific novelty of the research is in obtaining the deformability characteristics of reinforced concrete beams reinforced with a package of reinforcement (tape and steel bars with periodic profile) with different ratios in the case of static loads` action.

Works in the crypts in Szczuczyn had been carried out since 2013, however in this case the main aim of the work was to collect botanical samples to analyse the vegetation that was used in the early modern funeral rite. An important element during the work was the proper selection of places from which botanical samples were to be taken, as well as marking the samples and their further segregation. To this end, it was decided to prepare a common sampling system for all the burials.

Opis:
In the modern world, fast and efficient processing of non-digital (handwritten or typed) texts is the task of extreme importance. Similar to many other fields, optical character recognition (OCR) benefits from the application of machine learning (ML) which allows developing effective and accurate methods. In order to achieve good performance, a machine learning algorithm requires great amount of data. Nowadays, a large database of handwritten characters prepared by National Institute of Standards and Technology (NIST), USA, can be used for training an ML model. However, significant differences between the manners of handwriting exist in the US and Poland. That fact, along with the absence of Polish diacritical marks, causes the NIST database to be less useful for development of an OCR model for the Polish language. According to the best of the authors’ knowledge, no database with samples of Polish handwriting exists. The present research is focused at filling this gap, i.e. gathering and preparing an extensive database of Polish handwritten characters. The paper presents the very first database of Polish handwriting samples. The database is by far larger than all the datasets used in the previous attempts of implementing OCR for the Polish handwriting. It is also the first fully publicly accessible database of Polish handwriting of this scale. The same method and developed tools can be used to build handwritten characters databases of other languages.

Opis:
In this paper, we continue a topic of modeling measuring processes by perceiving them as a kind of signal sampling. And, in this respect, note that an ideal model was developed in a previous work. Whereas here, we present its nonideal version. This extended model takes into account an effect, which is called averaging of a measured signal. And, we show here that it is similar to smearing of signal samples arising in nonideal signal sampling. Furthermore, we demonstrate in this paper that signal averaging and signal smearing mean principally the same, under the conditions given. So, they can be modeled in the same way. A thorough analysis of errors related to the signal averaging in a measuring process is given and illustrated with equivalent schemes of the relationships derived. Furthermore, the results obtained are compared with the corresponding ones that were achieved analyzing amplitude quantization effects of sampled signals used in digital techniques. Also, we show here that modeling of errors related to signal averaging through the so-called quantization noise, assumed to be a uniform distributed random signal, is rather a bad choice. In this paper, an upper bound for the above error is derived. Moreover, conditions for occurrence of hidden aliasing effects in a measured signal are given.

Opis:
This research focuses on the ground water quality index in Ado-Ekiti State, Nigeria. Groundwater sample wells were randomly collected and their spatial locations captured using a handheld GPS. Water samples were taken from 45 wells and their physio-chemical properties were analyzed in the laboratory. Spatial distribution maps of the water quality parameters were then developed. Herein, the Kriging method of interpolation from geospatial analyst wizard in Esri ArcGIS software was deployed in the generation of thematic maps of water quality parameters. A drinking water quality index was subsequently developed to describe the overall quality of groundwater in the study area. Laboratory analysis of 34 wells showed water of acceptable use as it conforms to WHO standard, while 11 wells were found to have unsuitable water for domestic use. The results further show spatial variation in the water quality. The south central depicts poor water quality, fair water quality in the south-east, while the North, north east, north-west down to the south west depicted the best water quality.
