No full textLokum is a gelled product prepared by boiling a mixture of sugar, glucose and starch with the addition of flavors and dyes. To complete the current study were achieved threeTurkish delight assortments (strawberry flavoured, lemon flavoured and mint flavoured), fivefor each studied assortment, and were bought from different stores localised in Iaşi City. The criteria used for sensory evaluation were overall appearance and colour, aspect, smell, taste and texture. Chemical analysis consists in determination of moisture and dry matter content, total sugar and directly reducing sugar content. It was observed distinctly significant differences between all three types of lokum in terms of colour, general and section aspect and total average score. Very significant differences were registered for the smell and taste features. The only feature in which the differences were insignificant was the one regarding texture.Percentage of moisture presented a value of 17.23% in the case of the three lokum assortments, dry substance recorded an average value of 82.77%, percentage of total sugarhad a value of 73.76%, and percentage of directly reducing sugarwas 17.87%

Microbiological risk assessment represented by the psychrotrophic microflora from some meat products
No full textMeat products are one of the categories of food that is increasingly appreciated by consumers. The presence in meat
products of psychrotrophs is of particular importance for their quality, safety and freshness. Psychrotrophs can decrease
their quality or make them non-edible, either by their pathogenic action or by the degradation and production of toxic
metabolites. The aim of the study was to carry out a microbiological risk assessment regarding contamination of some
meat products with psychrotrophs. The research material was represented by 36 samples of heat treated meat products:
frankfurter, extra baloney and Victoria ham salami, collected between February - May 2019 from a meat processing
company, located in Transylvania. All the samples were analyzed for the presence of the main psychrotrophs involved
in spoilage processes: Acinetobacter spp., Pseudomonas spp., Moraxella spp., Lactobacillus spp., Aeromonas spp.,
Yersinia spp., and other bacteria from Enterobacteriaceae family. Psychrotrophic microbial load ranged between
7.0x102 and 5x104 cfu/g, 2x102 cfu/g and 8x102 and 3.2x106 for Victoria ham salami, extra baloney and frankfurters,
respectively. In case of frankfurters, the microbial population was represented by: Pseudomonas fluorescens,
Pseudomonas putida, Micrococcus spp., lactic acid bacteria, Moraxella lacunata, Ochrabactrum anthropi, and
unidentified Gram positive rods. Microbial populations in case of Victoria ham salami were represented by:
Pseudomonas fluorescens, Pseudomonas putida, Acinetobacter lwofii, Moraxella lacunata, Staphylococcus spp.,
Stenotrophomonas maltophilia, Streptococcus spp., and unidentified Gram positive rods. Microbial populations in case
of extra baloney were represented by: Pseudomonas fluorescens, Psychrobacter phenylpiruvicus, Micrococcus spp.,
Staphylococcus spp., Streptococcus spp., and unidentified Gram-positive bacteria. Following the microbiological risk
assessment regarding the presence of psychrotrophs in meat products, we conclude that psychotrophic microflora must
be monitored permanently, being dependent on the initial loading of the raw material, as well as on the hygiene practices
and temperature from storage area
Tourists’ motivations and preferences for agritourism activities
No full textThe agritourism is a category of tourism in full expansion worldwide. By its social and economic contribution
to the development of rural communities and farms, the agritourism became an attractive alternative for the
diversification of agricultural businesses. The main aim of the present paper is to identify, based on the international
literature of concern, which are the reasons that determine the tourists to choose agritourism as a form of leisure. The
studies carried out by specialists in different countries point out that the tourists’ preference for agritourism is highly
influenced by the context in which they are, and is generated by a wide range of “push” and “pull” type of factors. The
tourists have different expectations from a stay at the agritourism farm due to a large variety of motivations. According
to their nature, the reasons to practice agritourism are physical, emotional, cultural and personal, being subject to status
or desire for self-development. The physical and mental relaxation, the opportunity to spend nice time together with the
family or friends, the possibility to buy fresh fruits and vegetables and the wish to have direct contact with nature and to
enjoy the beauty of landscapes are the most obvious motives that determine the tourists to attempt an agritourism
experience. The participation at agricultural activities does not represented a major interest for agritourists. The
relationships between the tourists’ preferences for agritourism activities and their motivations show that they are
interested in those activities that are consistent with the initial reasons sustaining their decision to practice agritourism
Studies on biology and antibiosis resistance in mango (Mangiferae indica) varieties against mango mealy bug, Drosicha mangiferae green (Hemiptera: Margarodidae)
No full textMango is known as king of fruits. Among mango pests, mango mealy bug, Drosicha mangiferae (MMB), is considered one of the most destructive pests of mango orchards and other plantations. Whenever it enters in any orchards it is difficult to eradicate it from those orchards. The experiment was conducted at Entomological Research Sub Station, Multan-Punjab, Pakistan, during 2009 and 2010, to evaluate fitness of mango mealy bug on different varieties of mango and biology on ‘Chaunsa’ variety. Mango mealy bug, Drosicha mangiferae Green (Hemiptera: Coccoidea: Margarodidae), is matter of concern, as it is widespread pest of woody plants even in urban areas. A study was conducted on cultivar resistance and fecundity of mango mealy bug. The ‘Chaunsa’ cultivar of mango proved highly susceptible to mango mealy bug with maximum number of eggs laid, i.e. 335.90, and maximum weight, i.e. 0.239 g of the female, was recorded on the cultivar ‘Chaunsa’. The maximum length, i.e. 1.63 cm, and width, i.e. 0.80 cm of female, was observed on ‘Chaunsa’, which showed a susceptible response and did not differ significantly with the width of female on ‘Black Chaunsa’. Regarding biology, the 1st instar male and female duration on an average is 56.3 days, whereas the 2nd instar has 26 days. In case of the 3rd instar, female has duration 19.5 days and male has three days. Male has pupal stage, while it is absent in female. On an average two study years, the ranking of susceptibility of mango cultivars was as under: ‘Chaunsa’ > ‘Black Chaunsa’ > ‘Malda’ > ‘Fajri’ > ‘Retaul-12’ > ‘Langra’ > ‘Sensation’ > ‘Sindhri’ > ‘Dusehri’ > ‘Sufaid Chaunsa’ > ‘Anwar Reutul’ and > ‘Tukhmi’
Effect of row spacing and weed management practices on the performance of aerobic rice
No full textDirect-seeded rice alternative to transplanted rice system is less labor intensive, easier to plant, and consume less water. The advantages of direct-seeded rice have been proved by many research workers, but yet it is not very much adapted by farmers. Weeds reduce cost effectiveness of direct-seeded rice. A study was conducted to evaluate the effect of different row spacing and weed management practices on the performance of aerobic rice at Agronomic Research Area, University of Agriculture, Faisalabad, during summer season of 2013. Fine rice variety ‘Super Basmati’ was used for experiment in a randomized complete block design with factorial arrangements with three replications.
Hand drill sowing with row spacing comprised 15 cm, 22.5 cm, and 30 cm was practiced. Weed scouting hoeing (hand pulling is weed free treatment for comparison with the others and hoeing is a type of mechanical weeding) and preemergence herbicide, followed by postemergence herbicide, were the weed management practices. Weeds data and rice yield parameters were measured. Maximum reduction in weed density (86%) and weed dry weight (79%) was recorded for pre-emergence, followed by for post-emergence herbicide in crop sown at 15 cm row spacing
Study of semen parameters in captive brown bears (Ursus arctos)
No full textAs the Carpathian brown bear still represents one of the biggest populations of bears across Europe, the
study of its semen parameters as well as cryopreservation can help advancing the research regarding
conservation of genetic diversity for the endangered sub-species of European brown bear. The aim of this
paper was to study the parameters of the Carpathian brown bear semen and to attempt its liquid storage at
4°C. The study was performed on two bears, one belonging to the Turda zoo and another to the Libearty
bear sanctuary in Zarnesti. We obtained one sample of semen by electro-ejaculation from an 18 years old
captive brown bear from the Turda zoo, while the Libearty bear sanctuary provided us with a pair of testicles
from a 2.2 years old male, from which we obtained semen by retrograde flushing of the epididymis. We
analyzed those samples in 2 different extenders, before and after 24h refrigeration, using the CASA system
for concentration and motility and the flow-cytometer for viability. The results showed that semen obtained
by electro-ejaculation had good motility, which decreased after 24h of refrigeration, while viability was
adequately maintained. The epididymal extraction also provided semen with high motility and viability, but
liquid storage at 4°C was unsuccessful. This study is just a beginning, as it needs to be further continued, in
order to reach the goal of creating a sperm bank for the Carpathian brown bear and offer new data that
could help the preservation of endangered populations of other European brown bears

No full textInfertility in cows is one of the major problems with great economic implications. The purpose of this study was to identify by global and individual gynecological investigation major ovarian diseases and to determinate their incidence in the relation with hot season at Aberdeen Angus cows. The study was carried out in June 2019 in private unit in Timis county, Romania, on a number of 93 Aberdeen Angus cows in order to determine the prevalence of different ovarian diseases at this breed in a summer season. Gynecological investigations were performed in order to establish the prevalence of ovarian diseases in the summer season. The results showed different pathological entity variation. Thus, 50.22% of the animals taken into study presented ovarian hypofunction, 27.9 % presented corpus luteum , 0.93% polycystic ovary with uterine adherences and 7.44% ovarian follicle
Rural development approach in Romania's sustainable development strategy 2014-2020
No full textIn recent decades, Romania has faced enormous challenges in meeting its economic and social potential, agro-food and forestry, and rural areas. Gross domestic product per capita was and is much lower than the European Union average and significantly lower in all rural areas, demonstrating a very slow economic growth process. In terms of
development, rural areas are significantly different from urban areas and are characterized by persistent structural weaknesses (the large number of people employed in agriculture, the aging of the population, a large number of subsistence holdings, etc.); low added value of agri-food products; low labor productivity and productivity; poor entrepreneurship for the development of economic activities, low access to credits; a non-functional land market; a modest export orientation; insufficient investment in research and development; the continuous increase of regional disparities; a high share of the population at risk of poverty and social exclusion, etc. The present analysis aimed at highlighting the structural and dynamic evolutions of the main indicators that characterize the agriculture of Romania during the period 2011-2016, namely: macroeconomic indicators; production structures; cultivated areas and livestock; agricultural crop and animal production; prices of agricultural products. In Romania, the first Sustainable Development Strategy was implemented between 1997 and 1999 and was revised in 2008 (Sustainable Development Strategy 2013-2020-2030). In 2013, the National Strategy for Regional Development
2014-2020 was developed, which includes several aspects of ensuring sustainable development. In 2014, the Strategic Guidelines for Sustainable Development of the Carpathians (2014-2020) were approved
