Platelet-rich plasma (PRP) is an autologous concentrated cocktail of growth factors and inflammatory mediators, and has been considered to be potentially effective for cartilage repair. Animal clinical studies suggest that PRP is a promising treatment for cartilage injuries and relieving symptoms due to its three biological properties: an anabolic effect, enhancement of cartilage regeneration and inhibition of inflammation. The aim of this article is to analyse the available evidence on the clinical application of this biological approach to animals for the injective treatment of cartilage lesions and joint degeneration, and also to support the rationale for the use of platelet concentrates and to give indications on what to expect from intra-articular injections of platelet-rich plasma (PRP) in animals. This article is a summary of analytical research papers about the use of platelet-rich plasma as a treatment for the osteoarthritis. The intra-articular injections do not just target cartilage; instead, platelet-rich plasma might influence the entire joint environment, leading to clinical improvement. Many biological variables might influence the clinical outcome and have to be studied to optimize PRP injective treatment of cartilage degeneration and osteoarthritis.

The objective of the study was to investigate the correlation between the milk urea (MU), milk yield and reproductive performance using milk recording tests and the health check results. Weak to average negative correlation was found between MU and the milk yield (r = -0.44 and r = -0.34; p is greater than 0.05), milk protein (r = -0.22; p is less than 0.05) and milk freezing point (r = -0.33; p is less than 0.01). Higher milk fat was found in cow milk with MU below 30 mg dLE-1 in comparison with cow milk which had MU above 30 mg dLE-1, 4.0 ± 0.77% and 3.9 ± 0.75%, respectively. High MU fluctuations within a cow group can be observed if cows of different productivity levels are grouped together or if there are too many animals in one group. Correlations between MU and times of artificial insemination or the service period were not established, possibly due to successful veterinary measures. In conclusion we emphasize the necessity on large dairy farms to analyse MU concentration in relation to milk protein and fat concentration for individual animals and in each feeding group separately. The study was the part of the State Research Project (AgroBioRes) No. 2014.10-4/VPP-7/5; subproject VP29.

Actual and reliable meteorological data are necessary for building performance analysis. Since meteorological conditions vary significantly from year to year, there is a need to create a test reference year (TRY), to represent the long-term weather conditions over a year. In this paper TRY data model was generated by analysing every 3-hour weather data for a 30-year period (1984 – 2013) in Liepāja, Latvia, provided by the Latvian Environment Geology and Meteorology Centre (LEGMC). TRY model was generated according to standard LVS EN ISO 15927-4. The generated TRY contains from typical months that are included in TRY from a number of different years. The data gathered from TRY was compared with the climate data from the Latvian Cabinet of Ministers regulation No. 379, Regulations Regarding Latvian Building Code LBN 003-15. Average monthly temperature values in LBN 003-15 were lower than the TRY values that indicate on climate changes in this location. The results of this study may be used in building energy simulations and heating-cooling load calculations for selected region. TRY selection process should include the latest meteorological observations and should be periodically renewed to reflect the long-term climate change.

United States of America and European countries like Great Britain, Germany, Norway have long traditions in the development of scenic roads, special scenic routes for tourists, National Scenic Byway Programs. They have set criteria for road landscape planning and design, discussed the economic value of scenic roads. Scenic roads are also important for tourism, as well as visual and cultural countryside development in Latvia. Planning regions and regional communities in Latvia have strategic development plans and spatial plans. All of them include high value landscapes and protected, scenic territories. Some scenic roads are defined in these documents, but criteria for scenic road designation are set in every region individually. There are unlisted roads with high aesthetic value which could be protected. Common methods, criteria for the assessment of road landscapes and scenic road designation in Latvia are not developed. The aim of the research was to evaluate and understand the present situation of scenic roads in Latvia. An online questionnaire was carried out in order to find out peoples’ opinion about the road landscape quality. Spatial plans of regional communities and planning regions were examined. A field study of two sections of scenic roads was carried out. The research project was carried out from December 2014 to December 2015. Results show that current road landscape has a potential for development, and it needs improvements. The study gives a general insight into the scenic road situation in Latvia and provides basis for further research on scenic road planning and management.

This paper presents first results of monthly water stable isotope monitoring programme covering the most important surface and groundwater types in the Salaca River basin. The aim is to characterise the isotopic values of different water types in the Salaca River basin, and test if their contribution can be identified in the Salaca river runoff. A monthly groundwater and surface water stable isotope monitoring programme was initiated in August 2015 covering the most of the important surface and groundwater types in the study region – groundwater and surface water in the raised bogs, free-surface groundwater including artificially drained agricultural lands, water emerging from the Lake Burtnieks as well as Burtnieks and Arulika confined aquifers. Preliminary results show that stable isotopes are useful tool to identify distinct water components and their evolution. However, it is needed to continue monitoring programme to draw significant conclusions.

Afghanistan-ICARDA programs have field tested a range of rural development approaches and practices. Many of these are ripe for scaling-up at national level and can contribute to the EU-Afghanistan National Priority Programs (NPP) 2017-2021. The rural development plans of the Islamic Republic of Afghanistan have been supported by ICARDA – the International Center for Agricultural Research in the Dry Areas – since 2002, in areas including: provision of seeds and new crop varieties, improving management of land and water, introducing new agricultural production technologies and farming practices, and enterprise building for rural communities, with a special focus on women’s empowerment. These programs have helped develop the national agriculture sector – particularly in a number of remote areas – and the rebuilding the agricultural genetic diversity that was lost during the country’s conflict years. Development and research programs over the past two decades were funded by the European Union, Australia, USAID, IFAD, OFID, JICA (Japan), UKAID, The Netherlands, IDRC (Canada) and FAO.

The purpose of this report is to provide national- and state-level policymakers, private-sector investors, civil society, and donors with an analysis of the rural economy of Mon State and pathways to improved prosperity for its population. The analysis is based on a representative survey of rural households, which make up 73 percent of Mon State’s 2 million residents, and extensive interviews with farmers, traders, processors, local leaders, and government officials. Whereas some parts of the Mon State economy are quite dynamic, such as construction, others are stagnant and far from reaching their full potential. Furthermore, the dynamic sectors are heavily dependent on remittances from migrants to neighboring countries. The current pattern of donor investment is heavily focused on necessary infrastructure and energy investments, but with only very limited support to productive sectors, especially agriculture and fisheries. Major investments in education, both formal and vocational training, are also necessary to support the growth of a modern economy. The analysis in this report identifies options for more balanced growth, leading to a vibrant economy in which returning migrants can invest and find employment.

This chapter draws attention to the link between VCD and smallholder livelihood strategies that comprise a complex mix of subsistence and market-oriented activities and that are diversified to meet multiple livelihood goals and mitigate risks; and the authors address the related implications for the design and assessment of value-chain interventions. They question some of the underlying assumptions of NGOs, government agencies, and private-sector agents seeking to link smallholders to higher-value markets.

The purpose of this report is to provide information and analysis to government, civil society, and donors interested in improving the well-being of the rural population of Mon State. Specifically, the report analyzes the different sources of income for rural households, as well as their socioeconomic characteristics, with a view to identifying potential pathways to improving incomes, especially for poor households, and stimulating inclusive rural growth. The overall picture that emerges is one of an economy heavily dependent on services for local employment and on international migration for income. Like a two-legged stool, such an economy is potentially unstable in the face of external shocks. Diversification of the Mon State economy, including diversification and increased productivity within the agricultural sector, will lessen the relative dependence on external migration remittances and result in more resilient growth in the future
