Habitat selection by Asiatic black bear (Ursus thibetanus) in Siran and Kaghan Valleys, Pakistan

Asiatic black bear is present in variety of habitats like broad-leaves and coniferous forests, extending form sea level to 4300m elevation and change their habitat for food purpose seasonally. The present study was conducted at Kaghan and Siran Valleys, District Mansehra, Khyber Pakhtunkhwa, Pakistan to assess habitat of black bear. Line transect method was used for observation of bear signs. Twelve meter circular radius plots were selected for the concern vegetation’s i.e. (trees, shrubs and herbs) and three to six plots were placed in each transect. At the result of sign survey, thirteen different categories of bear signs were recorded and encounter rate was calculated for each sign. A total of 1858 signs were observed during field surveys. Total (81%) coniferous species were recoded among trees, with the highest appearance of Pinus wallichiana (34.22%) and Spruce spp (27.76%), similarly broad leaves trees (18.56%) were also recoded from habitat plots. Most of the signs were encountered in bushy areas, whereas high number of Viburnum Spp (60.29%) was present. It is indicated that black bear prefers blend of Coniferous Trees, Viburnum and Ferns Species; probably because these plants provide enough food, protection, and meticulous shelter because more than 80% of habitat composed of these three species. Currently habitat destruction and increase in human population are the up-growing issues for wild animals (especially Asiatic black bear), which is highly sensitive to such problems. High levels of conservation efforts are recommended for the protection of black bear habitat and to avoid human interference in their territory.

FOREST IN THE BASHKIRS' VIEW OF THE WORLD

В статье анализируются особенности восприятия лесного пространства башкирами. На основе языковых, фольклорных материалов сделана попытка раскрыть различные аспекты взаимоотношений лес - человек, образ леса в картине мира башкир. Как и в большинстве традиционных культур, в целом мифологический образ леса носит отрицательный характер. В фольклоре он часто описывается как тёмный, мрачный, неизвестный, таящий опасности, противопоставляясь обжитому и освоенному пространству селений. Лесной пандемониум также представлен в основном отрицательными персонажами. В целом образ леса в традиционной картине мира башкир предстаёт довольно неоднозначным. С одной стороны - это категория, связанная с потусторонним миром, неизведанная, «чужая» территория. С другой - лес издавна являлся источником различных благ - в виде строительного материала, пушнины, различных продуктов питания, укрывал от врагов. The article analyzes the features of Bashkirs' perception of the forest space. On the basis of the materials of the epos, folklore, folk ideas, an attempt was made to reveal the various aspects of the relationship between forest and man, the image of the forest in Bashkirs' world view. As in most traditional cultures, the mythological image of the forest as a whole is negative. In folklore, it is often described as dark, gloomy, unknown, fraught with danger, being contrasted with the inhabited and developed space of the villages. The forest pandemonium is also represented mainly by negative characters. On the other hand, in the domestic perception forest is valued for the benefits derived from it: shelter, food, protection from enemies. In addition, Bashkirs, distinguished by a developed aesthetic perception and contemplative thinking, appreciated its beauty, which is also reflected in folklore. In general, the image of forest in the Bashkirs' traditional view of the world appears rather ambiguous. On the one hand, it is the category associated with the other world, unknown, «foreign» territory. On the other hand, the forest has long been a source of various benefits - in the form of construction materials, furs, various food products, and it sheltered them from enemies.

Utilisation of Carp Skin Post-Production Waste in Binary Films Based on Furcellaran and Chitosan to Obtain Packaging Materials for Storing Blueberries

The aim of the study was to develop and characterise an innovative three-component biopolymer film based on chitosan (CHIT), furcellaran (FUR) and a gelatin hydrolysate from carp skins (Cyprinus carpio) (HGEL). The structure and morphology were characterised using the Fourier transform infrared spectroscopy (FT-IR) and atomic force microscopy (AFM). The FT-IR test showed no changes in the matrix after the addition of HGEL, which indicates that the film components were compatible. Based on the obtained AFM results, it was found that the addition of HGEL caused the formation of grooves and cracks on the surface of the film (reduction by ~21%). The addition of HGEL improved the antioxidant activity of the film (improvement by up to 2.318% and 444% of DPPH and FRAP power, respectively). Due to their properties, the tested films were used as active materials in the preservation of American blueberries. In the active films, the blueberries lost mass quickly compared to the synthetic film and were characterised by higher phenol content. The results obtained in this study create the opportunity to use the designed CHIT–FUR films in developing biodegradable packaging materials for food protection, but it is necessary to test their effectiveness on other food products.

Unauthorized Food Manipulation as a Criminal Offense: Food Authenticity, Legal Frameworks, Analytical Tools and Cases

Food fraud is a criminal intent motivated by economic gain to adulterate or misrepresent food ingredients and packaging. The development of a reliable food supply system is at great risk under globalization, but Food Business Operators (FBOs) have a legal obligation to implement and maintain food traceability and quality at all stages of food production, processing, and distribution. Incidents of food fraud have a strong negative impact on consumer confidence in the food industry. Therefore, local and international regulatory mechanisms are established to prevent or mitigate food fraud. This review brings new perspectives linking EU and US legislation, as well as new definitions and descriptions of the criminal aspect of food fraud incidents. It also describes certain new insights into the application of state-of-the-art methods and techniques that provide valuable tools for geographic, botanical, or other chemical markers of food authenticity. The review also provides an overview of the most common cases of food fraud worldwide from 2010 to 2020. Further research is needed to support the development of predictive models for innovative approaches to adulteration, especially when some valuable nutrients are replaced by toxic ingredients. A possible solution to minimize food fraud incidents is to increase the level of risk-based inspections, establish more productive monitoring and implementation of food protection systems in the supply chain, and implement better ingredient control and certification. National and international (e.g., regional) police offices for food fraud should be introduced, possessing knowledge and skills in food, food safety, food processing, and food products, as initial positive results have emerged in some countries.

Design and Development of Enhanced Antimicrobial Breathable Biodegradable Polymeric Films for Food Packaging Applications

The principle of breathable food packaging is to provide the optimal number of pores to transfer a sufficient amount of fresh air into the packaging headspace. In this work, antimicrobial microporous eco-friendly polymeric membranes were developed for food packaging. Polylactic acid (PLA) and polycaprolactone (PCL) were chosen as the main packaging polymers for their biodegradability. To develop the microporous films, sodium chloride (NaCl) and polyethylene oxide (PEO) were used as porogenic agents and the membranes were prepared using solvent-casting techniques. The results showed that films with of 50% NaCl and 10% PEO by mass achieved the highest air permeability and oxygen transmission rate (O2TR) with PLA. Meanwhile, blends of 20% PLA and 80% PCL by mass showed the highest air permeability and O2TR at 100% NaCl composition. The microporous membranes were also coated with cinnamaldehyde, a natural antimicrobial ingredient, to avoid the transportation of pathogens through the membranes into the packaged foods. In vitro analysis showed that the biodegradable membranes were not only environmentally friendly but also allowed for maximum food protection through the transportation of sterile fresh air, making them ideal for food packaging applications.

Limitation of Manufacturing Defects of the Selected Product in the Glass Mill

In the era of global market and internationalization of enterprises, an extremely important element influencing the competitiveness of companies is ensuring high quality of manufactured products, taking into account the requirements and expectations of buyers. At the moment when defects appear in the manufactured product, the production plant ceases to meet the expectations of customers. Not only is this related to the costs of production or complaints, but above all to the loss of credibility and good customer opinion. It is extremely important to identify and analyze the causes of this phenomenon as soon as possible, without allowing it to repeat itself. The problem of manufacturing defects becomes even more important when it poses a threat to the health or life of the customer. This also applies to products manufactured for the purposes of food protection. This article presents the results of the research that enabled the development of a method to reduce the production defects of a selected product in a glass factory. In order to achieve the goal, an analysis of the production process of the selected glass packaging was carried out, which allowed to identify defects and determine the causes and effects of their formation. Based on the presented research results, improvement measures have been proposed, consisting in developing a new organization of work in the area of quality control.
