1. Response of grey slug to entomopathogenic nematodes
ABSTRACT Biological control using entomopathogenic nematodes (EPNs) is known as an ecofriendly strategy in integrated pest management. The terrestrial slug Parmacella ibera is a major pest of vegetables and citrus trees in north of Iran. The heavy costs and environmental concerns of synthetic molluscicides led the study to use EPNs, against the slug P. ibera

2. Ocular tentacle malformation in Deroceras reticulatum (Mollusca: Gastropoda: Agriolimacidae)
Abstract Malformations in animals have long been known. In gastropod, natural and induced malformations are mentioned in different systems and in ocular tentacles, mainly linked to cases of parasitism and exposure to pollutants (molluscicides and chemicals). In this study we present a new malformation not documented in the ocular tentacles of slug Deroceras

3. Mini-channel Two Phase Flow of Hydrogen Peroxide: Decomposition with Silver Catalyst
ABSTRACT Hydrogen peroxide is a chemical compound which is commonly used as a disinfectant at lower concentrations. The chemical is called as a green propellant for space applications. Water and oxygen are the products after self-decomposition of the compound at higher concentrations. The reaction rate at lower concentrations can be enhanced by using catalys

4. Expression of E-cadherin, Slug and NCAM and its relationship to tumor invasiveness in patients with acromegaly
Pituitary adenomas account for 10–15% of primary intracranial tumors. Growth hormone (GH)-secreting adenomas account for 13% of all pituitary adenomas and cause acromegaly. These tumors can be aggressive, invade surrounding structures and are highly recurrent. The objective of this study was to evaluate E-cadherin, Slug and neural cell adhesion molecule (N

5. SIMULATION OF INTERMITTENT FLOW IN VERTICAL PIPES USING THE TWO-FLUID MODEL WITH DIFFERENT CLOSURE PARAMETERS / SIMULAÇÃO DO REGIME INTERMITENTE EM TUBULAÇÕES VERTICAIS UTILIZANDO O MODELO DE DOIS FLUIDOS COM DIFERENTES RELAÇÕES DE FECHAMENTO
Intermittent two phase flows are characterized by a succession of liquid slugs separated by bubbles of different sizes, with varying frequency. The prediction of this type of flow is very important, since it can be found in several industrial applications. In the present work, studies of intermittent flows in vertical pipes are performed, employing the Two F

6. EXPERIMENTAL STUDY OF ELONGATED BUBBLES IN HORIZONTAL TWO-PHASE INTERMITTENT FLOW / ESTUDO EXPERIMENTAL DE BOLHAS ALONGADAS NO ESCOAMENTO BIFÁSICO HORIZONTAL INTERMITENTE
The present work experimentally studied several relevant dynamic characteristics of gas-liquid intermittent flow through a horizontal pipe. All tests were performed in a test section formed by 50.8 mm internal diameter pipe using air and water as working fluids. The tests covered a region where the flow undergoes a complex transition from elongated bubble fl

7. Experimental investigation of horizontal gas-liquid slug flow by means of wire-mesh sensor
The monitoring and visualization of two-phase flow is of great importance either from technical/practical point of view for process control and supervision or from scientific/theoretical point of view, for the understanding of physical phenomenon. A wire-mesh sensor was applied to experimentally investigate two-phase horizontal pipe flow. Furthermore, some p

8. Statistical characterization of two-phase slug flow in a horizontal pipe
The present paper reports the results of an ongoing project aimed at providing statistical information on slugs in two-phase flow in a horizontal pipe. To this end, the flow was examined experimentally and numerically. On the experimental side, three non-intrusive optical techniques were combined and employed to determine the velocity field and bubble shape:

9. Evaluation of prognostic factors in stage IIA breast tumors and their correlation with mortality risk
Breast tumors exhibit extensive molecular and clinical heterogeneity. One of the most utilized breast carcinoma classifications is based on its molecular aspects and subdivides breast cancer into five major groups based on the expression of certain genes. In this study, we evaluated which factors are important in determining a prognosis after 5 years of foll

10. Avaliação do impacto ambiental e caracterização geoquímica de contaminantes em solo e água subterrânea na área do aterro de resíduos industriais da UTRESA na região do Vale dos Sinos, em Estância Velha, RS
A contaminação de resíduos industriais é um grande problema ambiental relacionado ao desenvolvimento industrial e urbano atual. A região do Vale dos Sinos, RS tem um histórico preocupante no gerenciamento e na destinação final de resíduos industriais ali gerados. Este estudo foi realizado na Central de resíduos da UTRESA, no município de Estância

12. Estudo experimental de escoamentos líquido-gás intermitentes em tubulações inclinadas / Experimental analysis of slug flow in inclined lines
This work analyses experimentally the flow properties of a gas-liquid mixture flowing in the slug regime in inclined lines. The experimental data are collected through a pair of impedance probes placed at 77D and 257D downstream of the air-water mixer in a 26mm ID pipe. During the tests air and water superficial velocities spanned, respectively, from 0,1 m/s
