The article considers and presents the main economic and biological parametres of new hashish-free varieties of androgenous hemp of the Central Russian type. The authors studied four zoned and recommended the following varieties of androgenous hemp into production: Diana, Ingreda, Antonio and Juliana. The research was carried out in 2013-2015 on the experimental base of Chuvash Research Institute of Agriculture. The objects of the research were androgenous hemp varieties: Diana, Ingreda, Antonio and Juliana. A comparative study of the varieties by a complex of economically valuable traits was carried out on a control seed plot. Experimental plots were 2-row, row width - 0.45 m, row length - 5.0 m, plot area - 4.5 m2. Repetition was sixfold. Sowing was carried out with a hand marker, the seeding scheme was 5x45 cm. According to the analysis, it was revealed that androgenous hemp has a high population uniformity by gender. It was established that early maturity of androgenous hemp varieties allows them to be cultivated both for seeds and fiber, which significantly increases the economic production efficiency. Androgenous hemp plants ensure simultaneous maturation of plants, which, in turn, allows mechanized harvesting to be carried out. A promising and noteworthy direction of hemp selection work is development of the so-called unisexual hybrids. It was revealed that the basis for creation of unisexual hemp is hybridization: dioecious varieties are taken for the maternal form, and monoecious varieties - for the fatherly one. In this regard, the question of creating the so-called unisexual hemp hybrids has been and remains an eternal topic of scientific research

Microorganisms such as bacteria and their derived biopolymers can be used in biomaterials and tissue regeneration. Various methods have been applied to regenerate damaged tissues, but using probiotics and biomaterials derived from bacteria with improved economic-production efficiency and highly applicable properties can be a new solution in tissue regeneration. Bacteria can synthesize numerous types of biopolymers. These biopolymers possess many desirable properties such as biocompatibility and biodegradability, making them good candidates for tissue regeneration. Here, we reviewed different types of bacterial-derived biopolymers and highlight their applications for tissue regeneration.

Farming Households

This study examined the economics of Philippine Lime or Calamansi production in selected Cities and Municipalities in Nueva Ecija, Philippines. The study was conducted within the rural farming households' framework, which constitutes the Philippine agricultural sector's backbone, producing about 5.8 percent of the total national agricultural output with the Central Luzon area, including the portion of the locale of the study. Using quota sampling, data collected from 50 selected calamansi grower- farmers from top 5 producing area in Nueva Ecija, the study measured the profitability of and the production efficiency of calamansi production in the area. Using a formal interview schedule, primary data was obtained from the sampled farming households. The study revealed that the typical calamansi farmer in the area as reflected in the instrument, thirty-two (32) or 64% which covers the majority of the respondents claimed that they fully owned the land they cultivated. Calamansi yield depends on its age as well. Fertilizer was found to harm output. Majority of them shared the same production and post–production practices, though a slight difference in terms of labor cost was observed. There were some who were already in the industry for quite a long time and learned other farming techniques and practices different from the conventional and were proven effective. For better efficiency, the land area cultivated, the farmers' educational status, accessibility to credit facility, and development of the rural areas and farmers' contact with the extension agents are some of the key issues to address. The local government in cities and municipalities may engage in an intensive campaign in encouraging capitalists to form cooperatives, processing and manufacturing houses to produce calamansi juice and other valuable products out of the calamansi fruit.

Productivity Indicators

In this article, in the form of publication, are presented key study findings that cover both methodological issues of measurement and comprehensive analysis of regional labor productivity, along with extended formulations of study results. Based on the experience of domestic and foreign statisticians, the author substantiates the system of regional labour productivity indicators required for its integrated assessment. In the author’s opinion, this system is needed in a formation of a single coordinated approach to the calculation of labour productivity from the perspective of branches, enterprises, and constituent entities of the Russian Federation.The introduction argues for the relevance of the issues related to measuring regional labour productivity, which is necessary to evaluate the progress of the Federal Project “Systemic Measures to Improve Labor Productivity” implemented under the national project “Labor Productivity and Employment Support”.The author justifies the solution to the problem of clustering regions by regional labour productivity indicator using a combined approach, which explains the trends in the economic development of the regions of Russia in the selected clusters.The final part of the article concludes that the study is relevant in assessing the factors of regional labour productivity needed to identify growth reserves or to prevent stagnation in economic development, measured, in particular, by means of a basic indicator of the economic production efficiency in constituent entities of the Russian Federation.

Coating Formulations

The Ji’an PM No. 3 is the first linerboard machine in China to use multilayer curtain coating technology. Since successful startup at the end of 2011, further development has been carried out to optimize running conditions, coating formulations, and the base paper to provide a product with satisfactory quality and lower cost to manufacture. The key challenges include designing the base board structure for the desired mechanical strength, designing the surface properties for subsequent coating operations, optimizing the high-speed running of the curtain coater to enhance production efficiency, minimizing the amount of titanium dioxide in the coating color, and balancing the coated board properties to make them suitable for both offset and flexographic printing. The pilot and mill scale results show that curtain coating has a major positive impact on brightness, while smoothness is improved mainly by the blade coating and calendering conditions. Optimization of base board properties and the blade + curtain + blade concept has resulted in the successful use of 100% recycled fiber to produce base board. The optical, mechanical, and printability properties of the final coated board meet market requirements for both offset and flexographic printing. Machine runnability is excellent at the current speed of 1000 m/min, and titanium dioxide has been eliminated in the coating formulations without affecting the coating coverage. A significant improvement in the total cost of coated white liner production has been achieved, compared to the conventional concept of using virgin fiber in the top ply. Future development will focus on combining low cost with further quality improvements to make linerboard suitable for a wider range of end-use applications, including frozen-food packaging and folding boxboard.
