The semi-arid region of Paraíba is known for the expansion of cultivated areas and agricultural produce, and the high yields and the quality of grapes. The objective of this work was to evaluate the quality table grapes for classification purposes according to the physical and physicochemical characteristics marketed in a local fair in the city of Areia - PB. The work was developed at the Laboratory of Technology of Agricultural Products (LPTA), Federal University of Paraíba (UFPB), Center of Agricultural Sciences (CCA), Campus II, Areia-PB. Table grapes were purchased at the free fair in the municipality of Areia. Two clusters were selected and analyzed according to the Standardization Primer and Classification of the Brazilian Program for Modernization of Horticulture, identifying the group, subgroup, class, subclass, category and the presence of defects (severe or mild). According to the evaluations carried out from the standardization primer, the fruits were slightly damage and/but not changing in their post-harvest quality. The fruits were classified according to commercial standards and suitable for human consumption.

The present study was designed to evaluate the metabolic effects of a high-fat diet based on trienantin, an uncommon medium-odd-chain triacylglycerol. Male Wistar rats (33.37 6 5.69 g) (n = 3610) were maintained for 6 weeks on a control diet (7 g soya oil/100 g) or a high-fat diet based on trienantin (40 g margarine, 4 g soya oil and 25.79 g trienantin/100 g), or a high-fat diet based on soya oil (40 g margarine and 29.79 g soya oil/100 g). The serum lipid profile, hepatic function and injury markers, and renal function and injury markers were determined. Samples of liver, stomach, kidney and small intestine were collected for histological analysis. The animals fed the high-fat diet based on trienantin exhibited a lower body weight gain in relation to the control group, between the second and fifth week of the experiment. There were no differences amongst the biochemical markers of the three groups (p !0.05). Lipid infiltration of the hepatocytes was detected in a similar manner in all groups (p !0.05). These data demonstrate that the high-fat diet based on trienantin did not promote adverse metabolic effects under the conditions of this study. This could serve as a reference parameter in the evaluation of the safety of its therapeutic application.

The Moringa oleifera Lam. it is a perennial, arboreal species, rapidly growing, resistant to drought and with leaves, flowers and edible fruits. With this research the objective to evaluate the effect of different substrates in the emergence and development of seedlings of Moringa. The experiment was carried out at the Plant Ecology Laboratory of the Department of Phytotechnics and Environmental Sciences, at the Center for Agricultural Sciences, at the Federal University of Paraíba. The experimental desing was completely randomized, with eight treatments T1= sand washed (control), T2= sand + coconut fiber, T3= sand + rice bark, T4= sand + bovine manure, T5= sand + pine powder, T6= sand + chicken manure, T7= sand + vegetable ash and T8= quail, with four repetitions of 25 seeds totaling 100 seeds for each treatment. The substrates were used in proportion 3:1, and these proportions were determined in terms of weight and all the sieved substrates, arranged in 6 cm x 29.5 cm x 45.5 cm trays, with an approximate capacity of 7 liters of substrate. The following parameters were evaluated: the emergence percentage, first count, emergence speed index, seedling height, plant height, root length, number of leaves, dry leaf biomass, stalk, root and total. The germination and initial development of M. oleífera seedlings were satisfactory in sand and favored when fibrous materials of vegetable origin (coconut fiber, rice bark or pine powder) or bovine manure were added to the substrate. The addition of manure sand from birds (chicken and quails) and vegetable ash did not favor the substrate for germination of Moringa oleifera Lam. seeds. Contribution/Originality: In search of alternatives to reduce costs and maintain the yield and quality of the production of Moringa oleifera Lam, we tested the use of alternative natural substrates. The influence of using different substrate alternatives on the nutritional quality of this crop is an economically viable and beneficial to the environment.Popularly known as moringa (Moringa oleifera Lam.), It is a species belonging to the Moringaceae family [1]. It is an arboreal vegetable that reaches 8 to 12 meters in height, has slight growth, the ability to resist in poor soils,

The National System of Conservation Units has defined a buffer zone as an area around a Conservation Unit, where activities must be subject to specific standards, in order to minimize negative impacts on ecosystems. Based on this discussion, this research uses remote sensing and geoprocessing and has as objectives: to map the use and occupation of the land, to simulate the buffer zone and to characterize the spaces of social and environmental conflicts of the State Park Mata do Pau Ferro, Areia-PB. Through the mapping of use and occupation was identified that the Park has 600 ha. Of these, 492 ha (82%) present a spectral response of forest vegetation (Seasonal Semideciduous Forest) in different successional stages, 54 ha (9%) represent clearings, with pioneer vegetation (Poaceaea and shrub), which present the same response spectral of crops and pastures, and 54 ha (9%) is the Vaca Brava reservoir, which presents its Permanent Preservation Area. The spaces of conflict are the protagonists of the buffer zone and summed represent 600 ha or 75% of the area. This fact can be considered an aggravating factor because all these economic activities are not being monitored and spatially symbolize a high degree of edge effect. Integrated management between the Conservation Unit and its buffer zone in this situation is urgent and should involve the surrounding social sectors, especially rural producers. An alternative would be the payment for Environmental Services and incorporate the agroforestry system.
