Role Of The State

In Vietnam, the construction of hydropower projects has contributed significantly in the cause of industrialization and modernization of the country. The place where hydropower projects are built is mostly inhabited by ethnic minorities - communities that rely primarily on land, a very important source of livelihood security. In the context of the lack of common productive land in resettlement areas, the orientation for agricultural production is to promote indigenous knowledge combined with increasing scientific and technical application; shifting from small-scale production practices to large-scale commodity production. However, the research results of this article show that many obstacles in the transition process are being posed such as limitations on natural resources, traditional production thinking or the suitability and effectiveness of scientific - technical application models. When agricultural production does not ensure food security, a number of implications for people’s lives are increasingly evident, such as poverty, preserving cultural identity, social relations and resource protection. Since then, it has set the role of the State in researching and building appropriate agricultural production models to exploit local strengths and ensure sustainability.

Abstract In the current process of producing vermicompost on a large-scale, the main challenge is to keep the worms alive. This is achieved by maintaining temperature and moisture in their living medium. It is a difficult task to maintain these parameters throughout the process. Currently, this is achieved by building infrastructure but this method requires a large initial investment and long-run maintenance. Also, these methods are limited to small-scale production. For large-scale production, a unit is developed which utilises natural airflow with water and automation. The main aim of this unit is to provide favourable conditions to worms in large-scale production with very low investment and minimum maintenance in long term. The key innovation of this research is that the technology used in the unit should be practical and easy to adopt by small farmers. For long-term maintenance of the technology lesser number of parts are used.

The importance of the agricultural sector in the economy of Azerbaijan is high. This sector has always been at the center of economic reforms by the government. This chapter overviews economic and trade policies of the government focused on the development of agricultural production since 1991. Authors carry out analysis of policy changes during separate development stages. The research output presents agricultural policy before the oil boom as mainly devoted to achieving structural transformation from centrally planned economy to the market environment. Within the oil boom period, the government provided substantial fiscal and technical support to the agricultural sector as well as applied tax incentives to farmers but did not pay attention to the transformation from family farming to medium and large-scale production. However, fiscal and macroeconomic challenges of post-oil boom period forced the government to focus on increasing efficiency of the subsidies and incentives and implementation of further agricultural reforms.

Background: Miniaturization of nanosuspensions preparation is a necessity in order to enable proper formulation screening before nanosizing can be performed on a large scale. Ideally, the information generated at small scale is predictive for large scale production. Objective: This study was aimed to investigate the scalability when producing nanosuspensions starting from a 10 g scale of nanosuspension using low energy wet ball milling up to production scales of 120 g nanosuspension and 2 kg nanosuspension by using a standard high energy wet ball milling operated in batch mode or recirculation mode, respectively. Methods: Two different active pharmaceutical ingredients, i.e. curcumin and hesperetin, have been used in this study. The investigated factors include the milling time, milling speed, and the type of mill. Results: Comparable particle sizes of about 151 nm to 190 nm were obtained for both active pharmaceutical ingredients at the same milling time and milling speed when the drugs were processed at 10 g using low energy wet ball milling or 120 g using high energy wet ball milling in batch mode, respectively. However, an adjustment of the milling speed was needed for the 2 kg scale produced using high energy wet ball milling in recirculation mode to obtain particle sizes comparable to the small scale process. Conclusion: These results confirm in general, the scalability of wet ball milling as well as the suitability of small scale processing in order to correctly identify the most suitable formulations for large scale production using high energy milling.

ABSTRACT Melanin is a pigment produced by organisms throughout all domains of life. Due to its unique physicochemical properties, biocompatibility, and biostability, there has been an increasing interest in the use of melanin for broad applications. In the vast majority of studies, melanin has been either chemically synthesized or isolated from animals, which has restricted its use to small-scale applications. Using bacteria as biocatalysts is a promising and economical alternative for the large-scale production of biomaterials. In this study, we engineered the marine bacterium Vibrio natriegens, one of the fastest-growing organisms, to synthesize melanin by expressing a heterologous tyrosinase gene and demonstrated that melanin production was much faster than in previously reported heterologous systems. The melanin of V. natriegens was characterized as a polymer derived from dihydroxyindole-2-carboxylic acid (DHICA) and, similarly to synthetic melanin, exhibited several characteristic and useful features. Electron microscopy analysis demonstrated that melanin produced from V. natriegens formed nanoparticles that were assembled as “melanin ghost” structures, and the photoprotective properties of these particles were validated by their protection of cells from UV irradiation. Using a novel electrochemical reverse engineering method, we observed that melanization conferred redox activity to V. natriegens. Moreover, melanized bacteria were able to quickly adsorb the organic compound trinitrotoluene (TNT). Overall, the genetic tractability, rapid division time, and ease of culture provide a set of attractive properties that compare favorably to current E. coli production strains and warrant the further development of this chassis as a microbial factory for natural product biosynthesis. IMPORTANCE Melanins are macromolecules that are ubiquitous in nature and impart a large variety of biological functions, including structure, coloration, radiation resistance, free radical scavenging, and thermoregulation. Currently, in the majority of investigations, melanins are either chemically synthesized or extracted from animals, which presents significant challenges for large-scale production. Bacteria have been used as biocatalysts to synthesize a variety of biomaterials due to their fast growth and amenability to genetic engineering using synthetic biology tools. In this study, we engineered the extremely fast-growing bacterium V. natriegens to synthesize melanin nanoparticles by expressing a heterologous tyrosinase gene with inducible promoters. Characterization of the melanin produced from V. natriegens-produced tyrosinase revealed that it exhibited physical and chemical properties similar to those of natural and chemically synthesized melanins, including nanoparticle structure, protection against UV damage, and adsorption of toxic compounds. We anticipate that producing and controlling melanin structures at the nanoscale in this bacterial system with synthetic biology tools will enable the design and rapid production of novel biomaterials for multiple applications.

History Of

Between the Civil War and the Industrial Revolution, four generations of the Stansfield family lived in Halifax—an upland parish in the West Riding of Yorkshire. Although its politics were calm, the century and a half between England's two great “revolutions” was not devoid of change in other respects. Significant social, economic, and cultural developments during this period laid the foundations for the ferment of the Industrial Revolution. The history of the Stansfield family is an excellent illustration of these changes, for there was a world of difference between the great-grandfather, Josias Stansfield, who was in his prime at the Restoration, and his great-grandsons, George and David Stansfield, who were in their primes a century later.For his part, Josias was recognizably a man of the middling sort. A yeoman engaged in farming and small-scale textile production, his economic activities and his social standing place him in the ranks of families who fell between the few gentlemen who lived in the area and the mass of simple artisans and laborers who had to struggle just to survive. Josias's great-grandsons, George and David Stansfield lived in a different world. By the mid-eighteenth century, Halifax's textile industry was increasingly dominated by large-scale production of which George's large putting-out concern and David's substantial export business were typical. George and David's social position was also quite different. No longer merely comfortable, these two second cousins were among the wealthiest residents of their respective townships, and they had assumed an appropriately significant share of the political and social leadership in the parish.

Abstract The years of activity of the PNZ (Państwowe Nieruchomości Ziemskie – State Agrarian Real Estate) fell into the period of post-war agricultural reconstruction and management of Recovered Territories. Initially, their main task was to prepare for the parceling out of large landed estates, which was important for the settlement campaign. The target task was to run specialized farms that would supply the entire agriculture with seed and breeding material. After the escape of S. Mikołajczyk, the communists changed the priorities of PNZ activity, which from then on were to deal with large-scale production, and above all, manage about 1,200 hectares of agricultural land. The vast majority of the area used by PNZ was located in the western and northern regions of the country. The best conditions existed in those areas for establishing a state sector in agriculture. In spite of many achievements, PNZ was liquidated because the communists wanted to get rid of the prewar staff of specialists, mostly landowners, from the enterprise. This decision was political in nature. State farms were then created to replace PNZ.
