This paper introduces the penal process in the Church addressing the gravest delicts committed against morals. This has undergone certain modifications in recent years along with the precepts of the penal law of the Slovak Republic concerning these kinds of delicts. Of great importance in this context was the Second Vatican Council, the Code of Canon Law promulgated in 1983 and the Code of Canons of the Eastern Churches that came into force in 1991. Responding to a series of scandals of a sexual nature surrounding clerics that were exposed towards the end of the last century, the Church adopted serious modifications to the penal law. The most significant reform was introduced during the pontificate of John Paul II who issued an apostolic letter Motu proprio Sacramentorum sanctitatis tutela in 2001. In 2010, Pope Benedict XVI revised the original text of the De gravioribus delictis and modified some of its sections. Pope Francis continued in the reform by issuing an apostolic letter Motu proprio Come una madre amorevole in 2016 in which he introduced the possibility of removing bishops from ecclesiastical office for negligence in relation to cases of sexual abuse. The reform initiative of the Apostolic See is primarily aimed at securing justice in the Church and safeguarding the faithful from immoral acts of the clergy. In addition, these reforms seek to maintain the high credit of the priestly vocation amongst God’s people by placing a great emphasis on the moral integrity of the ministry in line with Christ’s teaching.

A first-derivative UV spectrophotometric method, with or without the subtraction technique, was developed for the determination of biapenem in pharmaceutical dosage form in the presence of its degradation products. The method was based on the measurement of first-derivative amplitudes at zero crossing point (λ = 312 nm) and the peak-to-zero technique and validated with regard to linearity, limits of detection and quantitation, selectivity and precision. The observed rate constants for the degradation of biapenem were comparable to those obtained in the stability-indicating HPLC method. [...]

Zinc is a vital and beneficial trace element found in the human body. Though found in small proportions, zinc performs a variety of functions in relation to the immune system, cell division, fertility and the body growth and maintenance. In particular, zinc is proven to be a necessary element for the formation, mineralization, development and maintenance of healthy bones. Considering this attractive attributes of zinc, recent research has widely focused on using zinc along with silicate-based bioactive glasses for bone tissue engineering applications. This paper reviews relevant literature discussing the significance of zinc in the human body, along with its ability to enhance antibacterial effects, bioactivity and distinct physical, structural and mechanical properties of bioactive glasses. In this context, even if the present analysis is not meant to be exhaustive and only representative studies are discussed, literature results confirm that it is essential to understand the properties of zinc-containing bioactive glasses with respect to their in vitro biological behavior, possible cytotoxic effects and degradation characteristics to be able to effectively apply these glasses in bone regeneration strategies. Topics attracting increasing research efforts in this field are elaborated in detail in this review, including a summary of the structural, physical, biological and mechanical properties of zinc-containing bioactive glasses. This paper also presents an overview of the various applications in which zinc-containing bioactive glasses are considered for use as bone tissue scaffolds, bone filling granules, bioactive coatings and bone cements, and advances and remaining challenges are highlighted.

Polymers have been widely used in agriculture for applications including controlled release of pesticides and other active ingredients. The ability to predict their delivery helps avoid environmental hazards. Macromolecular matrices used as carriers in controlled release of agricultural active agents, especially pesticides, are reviewed. The review focuses on the advantages and mechanisms of controlled release. It includes biodegradable polymers in agriculture, their manufacturing methods, and their degradation mechanisms and kinetics. The article also presents a critical account of recent release studies and considers upcoming challenges.

In view of the recent emphasis on non-conventional chemistry, application of ultrasound in isolation of plant polysaccharides represents a viable alternative to traditional extraction processes. This review presents an extensive literature survey of ultrasound-assisted extraction of polysaccharides from different plant materials, particularly herbal plants and secondary agricultural plant sources. Targeted, multistep methods were applied with respect to differences in the types of polysaccharides and their location in plant cell walls. The effectiveness of the methods was evaluated according to yield and properties of the isolated polysaccharides in comparison to classical extraction methods. Substantial shortening of extraction time, reduction of reagent consumption and/or extraction temperature are the most important advantages of the ultrasonic treatment. In combination with sequential extraction steps using different solvents, sonication was shown to be effective in separation and/or purification of polysaccharides. The disadvantages of the sonication treatment, such as degradation and compositional changes of the polysaccharide preparations are discussed as well.

The bacteriological evaluation of hydrocarbon polluted soil in Obitti oil field in Ohaji Egbema was investigated to ascertain the presence of bacterial community in crude oil-polluted soil. Ohaji Egbema has experienced crude oil pollution in recent times due to the presence of crude oil exploration facilities including the Obitti oil field. Soil samples were collected from four (4) different points within the oil field with varying degree of crude oil pollution along with their corresponding control samples (unpolluted soil). The total culturable heterotrophic bacteria (TCHB), total culturable hydrocarbon utilizing bacteria (TCHUB), pH and total petroleum hydrocarbon (TPH) concentrations were monitored using standard procedures. The total culturable heterotrophic bacterial count ranged from 0.45±2.0x105 Cfu/g to 2.12±2.6x105 Cfu/g while total culturable hydrocarbon utilizing bacterial count ranged from 0.56±2.1x104 Cfu/g to 1.35±2.6x103 Cfu/g. pH ranged from 0.11±4.0 to 1.10±5.0 for the polluted soil samples while a range of 0.10±5.7 to 1.00±7.2 was recorded for the control samples. The TPH analysis revealed a high concentration of 9.51±5747.13 mg/kg to 3.45±7214.82 mg/kg for polluted soil samples which is above the DPR intervention limit of 5000 mg/kg for soils while the control samples recorded a range of 5.41±3118.29 mg/kg to 8.21±4285.02 mg/kg. This study has therefore revealed the ability of indigenous bacterial population to strive despite crude oil pollution and as such these hydrocarbon impacted sites can be harnessed for the isolation of hydrocarbonoclastic bacteria which can serve as a bio-resource for the effective bioremediation of hydrocarbon impacted environment.

W Polsce funkcjonują miejscowości o charakterze miejskim, posiadające wysokie walory kulturowe, które nie są stolicami gmin. W wielu z nich postępuje degradacja społeczna oraz dekapitalizacja infrastruktury (w tym cennego dziedzictwa). W artykule zaproponowano rozwiązanie w postaci instytucjonalnego modelu wsparcia skoncentrowanego na lokalnej społeczności. Model taki może być zatem próbą zmaterializowania zasad nowoczesnego zarządzania lokalnego definiowanego jako elastyczny model podejmowania decyzji oparty na luźnych powiązaniach poziomych pomiędzy różnymi aktorami (publicznymi i prywatnymi).

There are many townsplaces in Poland, whith high cultural values, which are not the capital district. In many of them society degradation and infrastructure depreciation (including the valuable heritage) appear. The paper proposed to solve the problem by the model of community led local development support. This model can be therefore an attempt to materialised a modern local government rules, defined as flexible model to decisions making support by loose horizontal conections between various players (public and privat).
