Guinea pig cecum structure in relation to digestion function
No full textGuinea pigs are often usen as animal models in investigations, thus there is an acute interest in these animals.
The apartenence of guinea pigs in the Rodentia order is still a matter of debate, which determined us to shed
a light on the microscopical structure of the cecum in order to understand whether this segment is responsible
for most of the digestion in this species. We harvested the cecum from 5 adult guinea pigs, brought for
necropsy examination in the Department of Necropsy (UASVM Cluj-Napoca). The samples were processed
for paraffin embedding and stained with three different procedures: Goldner’s trichrome method, PAS
reaction and Alcian blue stain. The cecum in guinea pigs presents the four characteristic tunics for the
digestive tract. The cecum has a rather thin wall in guinea pigs, the mucosa being the best represented tunic.
PAS-positive and Alcian blue-positive goblet cells are present in small numbers in both the surface and
glandular epithelium. The obtained structural information suggests that the digestion is only partially taking
place in the cecum in guinea pigs, completing the one taking place in the small intestine
The important record of Monolexis fuscicornis Forster, 1862 (hymenoptera, braconidae, doryctinae) in Turkey with notes on Trogoxylon impressum (Comoli, 1837)
No full textIn the present paper, Monolexis fuscicornis Förster, 1862 (Hymenoptera, Braconidae, Doryctinae) is recorded in Turkey for the second time and it is documented as parasitoid of Trogoxylon impressum (Comolli, 1837) (Coleoptera: Bostrichidae), firstly pest T. impressum (Comolli, 1837) record on fig plants. This damage to the fig plant and nutritional behavior with exit holes was observed for the first time with this work. In additionally, this record was firstly reported in the Southeast Anatolia region of the pest. Harmful has the potential to cause significant damage to fig plants over the years. It is necessary to studies whether the natural enemy detected on the pest is under the pressure of this pest. In this study, M. fuscicornis Förster,1862 is recognised as larva-pupa parasitoid of T. impressum, important pest in fig tree plantations in Turkey. This interaction could have significant implication in biodiversity conservation and pest management. Hence, this new parasitoid-host interaction on fig plants has highly significance in pest manage-ment and biocontrol, because it is thought that the damage will increase in the future
Enhancing the solubility and reclamation efficiency of gypsum with H2SO4
No full textAn effective reclamation procedure of saline sodic soils is removal of undesirable Na+ by addition of some Ca2+ source paralleled with leaching of this sodium out of root zone.
Nevertheless, gypsum being a direct source of Ca2+ is relatively insoluble in water. Its solubility can be increased with addition of H2SO4. Therefore, three years (2015 to 2018) study was plan to find out the optimal and economical level of H2SO4, which can increase the solubi-lity and reclamation efficiency of gypsum for saline sodic soil in rice wheat crop-ping rotation. Treatments included were: T1, Control, T2, gypsum @ 100% of GR, T3,
gypsum @ 100% of GR+10 kg H2SO4 acre-1, T4, gypsum @ 100% of GR+50 kg H2SO4 acre-1, T5, gypsum @ 100% of GR+100 kg H2SO4 acre-1. Before start of study, soil had pHs = 8.85, ECe = 4.85 (dS m-1), SAR = 43.82 (mmol L-1)1/2, GR = 4.10 (t. acre-1), BD = 1.65 (Mg m-3), HC = 0.33 (cm hr-1). Experiment was laid out in RCBD with three replications. Sulfuric acid and gypsum were applied (once) at the start of study in the
respective treatment plots. Recommended dose of fertilizers, 150-90-60 NPK kg ha-1
for rice (Shaheen Basmati) and 160-114-60 NPK kg ha-1 for wheat (Faisalabad, 2008) was applied. Yield and yield determining attributes of each crop were recorded at physical maturity. After harvest of each crop, soil samples were collected and were analyzed for ECe, pHs, SAR, bulk density and hydraulic conductivity. Pooled data analysis revealed that maximum growth and yield determining factors of rice and wheat were recorded
where gypsum was applied with H2SO4 at the rate of 50 and 100 kg acre-1. Soil physical and chemical properties, i.e. pHs, ECe, SAR bulk density and hydraulic conductivity were also substantially improved with combined application of gypsum and H2SO4 at the end of study. Both levels of H2SO4 at the rate of 50 and 100 kg acre-1 with gypsum proved equally to be the best in enhancing the solubility and reclamation efficiency of gypsum and
showed the statistically (p≤ 0.05) similar results in increasing the yield of rice and wheat crop and improving the soil physical and chemicals properties. Therefore, H2SO4 at the rate of 50 kg acre-1 is recommended as most economical and optimum level, which can be used with gypsum as an effective ameliorative strategy for the salt affected soils
Alternative treatments in wound healing in animals
No full textTreating wounds on a patient is a daily work for veterinarians in small animals practice. Wounds are not so simple to treat as we might think. It is important to assess the correct wound category in order to apply the right treatment. Antibiotics became challenging due to the worldwide problem of antibiotic resistance and so, alternative treatments started to emerge. In human medicine, people want to receive treatments which are the most natural as possible. Nowadays, Phytotherapy became more popular the last few years, even in veterinary medicine. Sea buckthorn is an ancient plant, very well-known remedy, since the dawn of time for its beneficial effects on the organism. In this study, we evaluated the effect of sea buckthorn oil on wound healing by second intention on rabbits, in comparison with Honeyderm, a product that is already on the market for veterinary medicine. The two products were applied on the same type of wounds but in different quantity per day and in comparison with a control one using saline solution. Histological examination highlighted better results in wounds treated with sea buckthorn oil. The cutaneous defects were filled with an abundant amount of immature fibrous tissue composed of large number of fibroblasts and new small capillaries, extracellular matrix and insignificant number of inflammatory cells. No significant differences were identified in the individuals of the control group and those of the Honeyderm group
The economic impact of tourism activities on agritourism farms
No full textThe fact that the rural zones are characterized by a high level of unemployment and a lower standard of living determines the orientation of the local population towards another income sources than agriculture. One of the farmers’ favorite options to diversify the agricultural activities is the agritourism. The international reference literature mentions
a series of determining factors that may positively or negatively impact the economic effect of tourism activities on the farms. The lack or insufficiency of the economic data regarding the agritourism businesses and the fact that the most part of researches on this topic is conducted on regional level lead to very different estimations of the value and
importance of agritourism. The economic impact of agritourism is, in generally, favorable for the agricultural household. In the case of small farms and of those that fight for survival, the involvement in tourism activities is very important in order to increase the total income. Within the agritourism household, the contribution of the tourism
activities to the generation of total income and its profit depends on the following: the farm’s size and characteristics, the development stage and the type of the agritourism business carried out, the entrepreneur’s knowledge and abilities in agritourism, as well as the features of the geographical region where this occurs. The revenues obtained from food services, accommodation and marketing of agricultural and handicrafts products have a significant contribution to the total income generated by the tourism activities. Regardless the size of the agritourism farm, the agriculture remains the main source of income, the tourism activity being complementary to the agricultural one. Still, between tourism and agriculture may occur also a competitive relationship regarding the use of some resources, fact which could diminish the economic benefits for the agritourism farm
Correlation between the quality of the blonde beer originating from a profil unit in the North-East of Romania and food safety
Get PDFNatural, traditional beer is an alcoholic beverage, naturally saturated with carbon dioxide, which is obtained from barley malt, water, hops and yeast for fermentation. This is the third most consumed drink in the world, after water and tea, and the oldest alcoholic beverage on the entire planet. In this context, the main purpose of the research was to analyze the quality of the different types of blonde beer within a profile unit in northeast of Romania. In order to identify the technological features of beer production, the technological flow within the study unit was followed. The researched material was represented by 20 blonde beer samples, which came from four different types of beer (Suceava clasic, Călimani, Bermas and Solca), produced in the study unit. The samples were analysed organoleptically and then subjected to physico-chemical analyzes, determining: apparent extract, real extract, pH, alcohol concentration, total acidity, bitter value and CO2 concentration. Sensory analysis was performed by the scoring method, evaluating the appearance, colour, smell, taste, CO2 impregnation and persistence of the foam, the four types of beer evaluated having a good or very good quality. pH is one of the most important parameters regarding the taste and beer stability, the values obtained falling within the range 4.35-4.8, imposed in the study unit by product standards. CO2 concentration is another important parameter, all four types of blonde beer falling within the range of 0.3 - 0.5%. After analyzing all the results obtained, it is concluded that these products comply with the quality standards imposed by the legislation in force
Eco-friendly management of flower thrips and pod borers of mungbean through sesame intercropping
No full textEffectiveness of sesame intercropping in mungbean for the management of flower thrips and pod borer of mungbean was studied at Pulses Research Centre, Ishurdi, Pabna,
Bangladesh, during two consecutive season of kharif-I 2017 and 2018. Sesame intercropping in mungbean reduced flower thrips infestation and pod borer infestation significantly in both the years. Among the intercropped treatments, mungbean: sesame at 2:2 row ratio arrangements was found the best intercropping arrangements in reducing
flower thrips and pod borer infestation. Sesame intercropping showed statistically
similar performance in reducing pod borer infestation, as like as insecticide spraying
(Imitaf 20 SL @ 0.5 ml/l). Mungbean equivalent yield varied depending on the prevailing weather condition of the cropping season and market prices of both mungbean and sesame, but the total production was always higher in intercropped treatments than sole
cropping of mungbean. Hence, sesame intercropping in mungbean might be ecofriendly
management approach against flower thrips and pod borers of mungbean providing higher production and benefit
The importance of implementing a HACCP plan in food service operations and restaurants
No full textThe European Union has shown that the post-industrial market economy has led to the production of food products above the level of consumer needs in the member states. This development has generated new types of issues, due to the production of food at industrial scale. In order to cope with food and nutrition illnesses and to restore consumer confidence in food safety, the European Commission has launched a series of new legislative amendments on food safety (Marin V. et al, 2007). The Good Hygiene Practices Guide in restaurants establishes, according to the legislation in force, a set of rules referring to the part of food hygiene, which must be followed and applied in restaurants. Potential risks of contamination of food and/or beverages are identified in these plans and a series of measures are developed to prevent these risks. The plan also includes the hygiene rules that must be observed by the employees and the kitchen staff. Operators operating in the field of food must guarantee for its products, comply with the legislative requirements and permanently implement these requirements, in order to release for consumption safe products for the final consumer. The purpose of this paper is to keep in mind the scope of this study focusing on the storage, handling, processing and distribution of all products, including the cooked product to be consumed. Thus, all biological, chemical or physical hazards that may occur during the cooking process of the product are taken into account. The HACCP team will ensure that all foodstuffs used in the preparation of cooked products comply with food safety legislation
Posibilitatea utilizării plantelor de tomate ca biosenzor în sistemele de fertilizare
No full textThe response of plants to external stimuli is manifested by different physiological and morphological changes. The results presented in this paper are related to the "neurophysiologyof plants" and quantify the behavior of the plants to external stimuli, respectively the availability of water and nutrients, behavior expressed by quantitative modifications of the electric potential. The potential differences were continuously monitored, under controlled environmental conditions, in the greenhouse of the Institute of Agriculture and Environmental Research, within the UASVM Iasi, with readings 5 to 5 seconds, using two electrodes inserted into the stem of tomato plants, connected to a pico-ammeter. The systematic models of the variation of the electric potential, with values between 4.6 and 5.8 nA, can be used as tools for early evaluation of the conditions of water and nutritional stress, including the use of the system as a biosensor forfertigation
Researches on the implementation of the forest cadastre using the GNSS technology and the remote sensing
No full textIn Romania, about 27% of the land area is the forest fund. Sustainable development of forest involves their inventory and permanent updating in order to achieve a precise cadastral record. The land that are part of the forest cadastre are mainly represented by wooded land. The work consists in identifying and delimiting the cadastral area of a forest plot using modern ways of locating and tracking changes in time. The research aims to determine the modern aspects regarding cadastre and forest management issues, as well as how to create a database of the type of Geographic Information Systems, necessary in the context of the development of forest resources. In order to achieve the proposed
objective, modern technologies for field measurements were used, such as high-precision Trimble GNSS systems, capable of providing a high degree of precision and productivity. Thanks to the built-in technology, GPS receivers, receives signals from all existing satellite constellations, ensuring a high quality of the measurements made. The studied
area was also analyzed using satellite imagery which allowed the delimitation of forest boundaries through the digitization process. The use of very high resolution satellite imagery ensures high digitization accuracy, taking place in a shorter time than the terrestrial measurement method. Inventory of forests also involve the registration of plots in the Land Book. Through the ETERRA 3 application, the areas entered in the integrated national cadastre and land register can be viewed, interrogated and updated at all times. Since clearance is a major current problem, the most accurate and efficient cadastral survey and record keeping of forest enables sustainable forestry development in order to ensure a good quality of life
