Avaliação dos resíduos sólidos gerados no Restaurante Universitário da UNESP de Rio Claro: uma análise do potencial de compostagem

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, seus incríveis números e seus segredos

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.

Comparación de la conductancia hidráulica dentinaria, de acuerdo al tiempo de aplicación de desensibilizantes con base de oxalatos

ABSTRACT. Introduction: an in vitro model was used to measure the hydraulic conductance in human dentin discs treated with oxalic acid for 15, 30 or 60 s maintaining the occlusive effect and measuring 7 and 14 days after application. Methods: 45 dentin discs measuring 1 mm thick were obtained from human third molars which were free of caries and in no occlusion; the samples were obtained from patients aged 16 to 30 years. Discs were sorted out into three study groups (n = 15) depending on the time of application of a commercial solution of oxalate-based dentin desensitizer (DD) (BisBlock®) which contains ˂ 5% oxalic acid of 1.5-1.8 pH: in group A the agent was applied for 15 s, in group B it was applied for 30 s, and in group C for 60 s. The hydraulic conductance of each disc was calculated after acid etching, which corresponds to the maximum permeability of discs (100%) after immediate application of oxalic acid, as well as seven and fourteen days of storage in saline solution. The statistical analysis was done with ANOVA test and post-hoc Games-Howell test. Results: 35,46 ± 23.41% in Group A, 36.34 ± 15.88% in Group B and 24.99 ± 14.99% in Group C, showing that the use of DD for 15, 30 or 60 s decreased permeability in a statistically significant manner (p <0.05). Conclusions: DD was effective in reducing hydraulic conductance regardless of application time, but this reduction was temporary only, since after seven days permeability returns to values close to those of baseline.

Aplicação em subdose do haloxyfop-methyl na aveia-preta

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

Tumor odontogênico queratocístico e considerações diagnósticas

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.

Tumor odontogênico queratocístico: considerações clínico-cirúrgico

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.

Tumor odontogênico queratocístico: relato de caso

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.
