A consequence of population growth is the increased generation of solid waste, which requires environmentally and economically viable suitable disposal sites. The scarcity of such sites makes necessary to adopt non-generation measures, reduction, reuse , recycling and treatment of solid waste before final disposal of waste. This paper presents the quantification and qualification of organic waste generated in each sector of the University Restaurant (UR) , by proposing indicators of waste generation per meal (index of waste) . Then, from the characterization of the waste management practices adopted internally, evaluates the potential deployment of the composting process for organic waste, with signaling for opportunities to improve waste management. The diagnosis of waste generation was made based on data collected during the period of 10 days. The waste were classified into 3 groups (organic, recyclable and waste) in each sector of the restaurant ( pre preparation , kitchen and tray return) . The results reveal that 33 % of the waste generated in the UR currently has the potential to be composted in a suitable place on campus. Every meal served generat approximately 124g of waste, of which 35g are organic waste of the pre preparation sector, 49g are remnants of food in the tray’s return and 40g are other kinds of waste, including recyclable and non recyclable. You can still get a higher percentage of compostable if the trays pre-wash is not performed with detergent and water. To minimize the generation of waste trays can be replaced by plates and skimmers and ladles can be replaced by smaller ones. The food exposed in the counter but not consumed, can be distributed to students after the restaurant is closed so this material would not be disposed in the garbage

O DNA existe por um único motivo – criar mais DNA. Em cada célula do nosso organismo, o filamento estendido de DNA chega a ter cerca de 2 metros. Se você imaginar que em nosso corpo há perto de 10 trilhões de células, você terá uma ideia da enormidade de DNA que nós possuímos. Assim, se todo o seu DNA fosse emendado em um único filamento, seria tão comprido que se estenderia da Terra à Lua, ida e volta, várias vezes. Pudera, você é proprietário de 20 milhões de quilômetros de DNA. Seu corpo, em suma, é uma máquina de produzir DNA e sem ele você não conseguiria viver. Mas o próprio DNA, apesar de ser considerado “a base da vida”, não está vivo. Ao contrário de qualquer outra molécula, ele é, por assim dizer, “inanimado”. Não é reativo e quimicamente inerte. Por essas razões, pode ser recuperado de restos de sangue, de sêmen, ou de pele secos há muito tempo – milhares de anos, até.

One of the major constraints to sustainable of the tillage is the rapid decomposition of dry the matter. One of the mechanisms known to facilitate this process is the interference in pathways of polymers of lignin from tests of application of low doses of herbicide based on the relation that higher the content of the lignin greater the resistance to degradation. With this purpose, the herbicide Verdict * R (haloxyfop-methyl) was used to verify the effect of low doses at the height of the plants, productivity of dry matter and in the metabolism of the lignin in plants of black oat. Preliminary tests in the greenhouse were realized for adjustments ​​to the best low doses to be applied in the definitive experiment in the production area. The results obtained were 24% of increase in productivity in the experiments conducted in greenhouse, from the application of 3.125g of the active ingredient of the haloxyfop-methyl per hectare, in this subdose no changes was observed in growth and content of lignin in plants of black oat. In the field, the concentration of 2.5g i. a. ha-1 of haloxyfop-methyl decreased in 9% the lignification rate without interfering with the height and productivity of the plants, this being favorable to the degradation rate of stubble tillage on outcome

Keratocystic odontogenic tumor (KCOT is benign, featuring controversies in diagnosis and treatment. It occurs mainly in the region of the mandibular angle, which may or may not be related to a tooth and whose importance is due to its aggressive behavior and high recurrence rate. The causes of high rates of relapse observed in this lesion are dependent on factors such as age, location and size of lesion, gender, type of treatment and histological variant. The thin capsule and friable connective tissue of KCOT may favor the retention of epithelial debris responsible for the high proliferative capacity of this clinical entity. Due to the aggressiveness with its recurrence this paper aims to conduct a literature review addressing clinical and imaging aspects, composes the histopathological diagnosis of KCOT.

Introduction: The tumor odontogenic keratocyst (toq) is a benign disorder, which is controversial in its diagnosis and treatment. It is characterized by a true neoplasms arising from remnants the dental lamina. It occurs predominantly in the angle mandible, which may or may not be related to a tooth and whose importance is due to its aggressive behavior and high recurrence rate. The causes of the high recurrence rates. The thin capsule and friable tissue may favor the toq retention of epithelial debris and, moreover, the presence of satellite cells in the lesion site is responsible for the increased proliferative capacity of clinical entity. Objective: To present the peculiarities toq inherent in using a clinical case of toq in mandible. Case report: TOQ in the jaw in patient, 16 years old male presenting important lesion radiographically radiolucent related to the impacted tooth. Final comments: In consideration of the high rate of recurrence chosen treatment proved effective and was not any evidence of recurrence.

Introduction: The odontogenic keratocyst tumor (OKT) derived from dental lamina rests with particularities and specific histological features, with high rates of relapse and aggressive clinical behavior. Presents certain predilection for males, affecting the mandible of 60% to 80% of cases may be related to impacted tooth 25 to 45% of cases. Objective: To highlight the clinical, histopathological and imaging procedures of the OKT, as well as discuss the treatment of this injury. Case Report: To report a case of 10 years of age to look for the orthodontist to correct anterior open bite was observed in panoramic radiography radiolucent area in the region of the body of the mandible associated with pathological inclusion of the lower premolar. It was performed an incisional biopsy of the lesion and the histopathologic diagnosis was odontogenic keratocyst tumor. It was performed a CT scan to assess the extent of the injury and its relation to anatomic structures. How to conduct, we opted for the extraction of the deciduous molar and enucleation of the lesion, preserving the premolar included. The same goes on clinical and radiographic control 18 months, after removal of OKT obtaining the eruption of premolar that was involved in the injury. Final Comments: It is necessary to adopt protocols that include dental care knowledge of oral diagnosis, medical history and careful clinical evaluation without forgetting the need for histopathological confirmation.

The sialolithiasis is characterized by the formation of calcified structure called sialolith within the salivary ductal system. Although its etiology is unknown, it is believed that is from the deposition of calcium salts around an accumulation of organic leftovers in the lumen of the duct or be resulted by chronic sialadenitis and partial obstruction. In this study, the authors describe a case of a male patient, 46 years old, brown, who presented the complaint “pain under the tongue.” The presence of a hardened nodule located in the left sublingual fold was observed through intra-oral exam. Current considerations about treatment, clinical and radiographic characteristics were addressed in this work.

A displasia cemento-óssea é o tipo mais comum dentre as lesões fibro-ósseas, podendo apresentar-se de 3 maneiras: periapical, focal e florida. Paciente parda, de 53 anos, compareceu com queixa de “secreção na gengiva” e histórico de exodontia na região há 8 meses. À inspeção apresentou uma leve tumefação na região vestibular posterior esquerda da mandíbula e uma pequena fístula drenando pus. Realizou-se uma radiografia panorâmica, que revelou uma lesão de radiopacidade mista na região de molares inferiores direitos, medindo 2 cm de diâmetro; outra lesão radiopaca na região de pré-molares esquerdos, de 6mm de diâmetro - ambas bem delimitadas; e outra área radiolúcida com radiopacidade central, com halo radiopaco na região infectada, medindo 1,5 cm de diâmetro. O diagnóstico presuntivo foi de displasia cemento-óssea infectada, cisto periapical infectado associado à displasia e osteomielite. Após antibioticoterapia, realizou-se biópsia e curetagem da área. Microscopicamente apresentou áreas de tecido cemento-ósseo em forma trabecular e no local onde deveria haver tecido fibroso, presença de biofilme bacteriano, conteúdo hemorrágico e restos necróticos. No tecido de granulação removido observou-se intenso infiltrado inflamatório e áreas de calcificação cementóide. As características microscópicas juntamente com os achados clínicos e radiográficos levaram ao diagnóstico de osteomielite aguda supurativa secundária a lesão fibro-óssea, sugestiva de displasia cemento-óssea florida.

This work presents the results of the efficiency of three protection methods of roads slopes, against the development of erosion processes.The methods anlyzed were: (1) grass planting "San Carlos" (Axonopus compressus), (2) litter, composed of remains of branches and leaves of eucalyptus E. Grandis, and (3) Compacted soil cover with a local soil with properties more resistant to erosion processes.The experiment consisted of assembly of four rectangular cells with 6 meters, three for protection systems in study and one was kept unprotected to evaluate the efficiency of the methods in study.The determination of the amount of eroded sediment was based on the sum of the solids in suspension and stored sediments in the geotextile bags.The results showed that, compared to the unprotected cell, the litter obtained a reduction of soil loss of 90%, while the grass enveloped and reduced 80% and 65% respectively.
