The study aims to present the results obtained following the burned patients micrografting, from the perspective of analyzing the physical and chemical properties of polyamide as a support for skin micrografts. To carry out the project, the data was obtained from the use of 100 micrografting kits with polyamide support which were analyzed and the results were interpreted in order to obtain relevant information regarding the effect of polyamide in accelerating the healing process, the rate of postoperative complications, as well as the acceleration in integration of the skin grafts. The comparative analysis was performed with a control group consisting of 108 free split skin grafts covered with classic cotton tulle. The conclusions of the study show that the use of polyamide in the therapeutic protocol of micrografting accelerates the process of grafts integration, while reducing the rate of postoperative complications, as well as decreasing the lenght of hospitalization.

The chemical composition and nutritional value of food products are determined both by the raw materials from which they come and by the contribution of auxiliary materials. These substances, for the most part, are added in order to improve some properties of the products. Respecting the legislation regarding the allowed limits of additives in food products, it is necessary to pay special attention in order to maintain the safety and health of the population. The generic term pectin includes polygalacturonic acids (acid polysaccharide) whose carboxylic groups are esterified in varying proportions with methyl alcohol and partially neutralized with calcium or magnesium ions. The specific properties of pectic substances, due to which they have uses in the food industry, are the gelling capacity and the stabilizing capacity of emulsions. Also, the gel does not show the phenomenon of syneresis, does not absorb moisture from the external environment and is resistant to sugaring. In our country, pectin is obtained industrially from apple pomace, a by-product resulting from obtaining juices and has multiple uses. The functional properties are largely determined by the degree of methoxylation of polygalacturonic acid, which determine the degree of esterification of this polysaccharic acid.

Food additives (commonly known as E) are substances that are not normally consumed as a stand-alone food and are not used as characteristic food ingredients with or without nutritional value. The aim of the paper was to observe the presence of food additives in some products, such as cold cuts and spreads, more frequently used in children's food, which have high visibility on the shelf, due to the attractive packaging, but also advertising messages in the media. The method applied was the observation of components from the label of products for children and the determination of those that are harmful to human consumption. A questionnaire was also developed to determine consumer opinion. This study was conducted in the Bucharest area, in three large shopping centres. Sodium nitrite (E 250) is found in all foods for children under study. The parents have the obligation to choose the right nutrition for their children. 52.9% of adults admitted that they did not read the label of the food they bought. It is necessary to continuously educate consumers about potentially dangerous ingredients, added to food, reading the label, to determine their presence in the chosen product on the shelf, giving up buying food on the principle of quantity or reduced price to the detriment of quality.

The encapsulation of fertilisers and pesticides represents an important process in agriculture and plays a significant role in the crop productivity. In literature, there is an explosion of data regarding the production and use of biodegradable polymers and the encapsulation of fertilizers, pesticides or their mixtures is also recorded. The aim is to control the release of the active substance over time, not only to extend the period of time during which it acts but also to prevent the pollution of ground water due to the washing processes. At the same time, it also aims to improve working conditions regarding the transport and use of fertilizers and pesticides. [ABSTRACT FROM AUTHOR]

During the performance of any activity and especially on the effort in specific sports activities, the body expends energy in calories. Using an adequate diet we follow body energy reserves forming needed during effort and contests. Performance Athlete diet will be more strict to cope with the physical effort. Therefore we recommend that athletes must consume high caloric density foods like cereals, juices, honey, fruit yoghurt, hydrating beverages, vegetables, fruits, chicken, turkey and beef, fish, eggs, soy products etc. All these are required not to be absent from athlete diet. The research method was based on bibliographic study and experimental methods in order to determine the best food groups required in an athlete's diet. [ABSTRACT FROM AUTHOR]

Liquid fertilizer, in the current period, represents an important share for agricultural crops. From the research of the herbicides used worldwide it is ascertained that in most of the cases mixes of products are used to obtain a wide action range. Usually mixes of herbicides and complementary action are used, thus obtaining products having a wide action range which enables their use in various fields. The use of the herbicide mixes has important technical and economic benefits: the number of crops treatments are significantly diminished, therefore of the equipment, manpower, thus obtaining important diminishment of the energy consumption.

This work presents the particularities of the diet in some sporting branches depending on the nature of the effort, the organs requested, the climatic conditions etc. Taking into account these criteria, the amount of nutritious substances found in food are established, in order to satisfy the average energetical consumption of a sportsman weighing around 70 kg who practices a certain sport. To help the body recover after exercise sportive must facilitate detoxification and the body’s water intake must be maintained at constant limits. The research method presented is based on bibliographic study and experimental methods in order to determine the nutritional values needed for a consistent diet. The sports performances obtained worldwide have reached values that years ago seemed inconceivable. For their achievement, the athletes are subjected to a complex training process, in which the effort often requires the body to exceed its maximum physiological limits. [ABSTRACT FROM AUTHOR]

The forestry measures applied consist in adjusting and decreasing of the forestry personnel for obtaining wooden material as required, with a good physiological state, without any specific flaw on its surface. The IV production Unit of Chirnogi belongs and develops in district Campiei Burnasului, it is administered by Mitreni SilvicDistrict, while being a public property of the state in the R.N.P. Romsilva. Thinning shave been done in UPF IV Chirnogi on a surface of 41.16 ha with a volume of 455 m3 and a 46 m3 annual average. The major modifications have been done by assignations in the parcel and underlake area in UP III Frasin Ulmeni. [ABSTRACT FROM AUTHOR]

Following the research executed in a vegetal farm, the analysis of several types of plants assortments (sunflower, autumn barley, corn and wheat), with regards to the agricultural technologies applied, as well as their economic impact, with the purpose of determining improvement measures regarding structure of cultures and economic-financial performances within future years. The yields per unit area were determined by the varieties and hybrids used in each crop, by the applied crop technology, by the quality of the agricultural work carried out and by the pedological and climatic conditions. The average yield on crops was as follows: 3,500 kg/ha for wheat, 5,000 kg/ha for winter barley, 2,500 kg/ha for sunflower, 6,000 kg/ha for maize. The total crop yield was conditioned by the production capacity per unit area and cultivated area. Thus, total crop yields were as follows: 2,975 t wheat, 750 t barley, 1,375 t sunflower, 600 t corn. The obtained products were fully utilized on the market, with the exception of wheat. Of the total production of 2,975 t of wheat, 950 t were allocated to the landowners in the company, each providing an in-kind rent of 500 kg of wheat per hectare. Therefore, only 2,025 t of wheat became the commodity production, meaning 68.06% of the total production obtained in this crop. [ABSTRACT FROM AUTHOR]
