Entrepreneurial Characteristics and Strategic Actions: a Case Study of a Brazilian Industry in the Dairy Sector
Tatiana Marceda Bach, Silvana Anita Walter, Valéria Silva da Fonseca and Jansen Maia Del Corso
The aim of this article is to analyze the relationship between the entrepreneurial characteristics of the founders of a Brazilian industrial company in the dairy sector and the formulation of their strategic actions. For this purpose, the professional background of the founders is analyzed before and after the establishment of the company, as well as the environment context at play in the formulation of the main strategic actions. The findings showed that while the founders of the future company were employed at a company in the same sector, they already wished to have their own enterprise to produce powdered whey. As owners of a pioneer industry in Brazil, purchasing whey in natura, they had to create processes to solve new problems and make investments that were unprecedented in Brazil. This required characteristics such as creativity, innovation, persistence, initiative and orientation to goals on the part of the founders. It can be concluded that the founders’ entrepreneurial characteristics aided the formation of the company’s strategic actions. The present study contributes to the literature by identifying the entrepreneurial characteristics of the founders and examining how they relate to the strategic actions formulated in organizations, using the entrepreneurship approach and strategy as practice.

Marine wastes present effects major environmental and economic. Misfortune and the monitoring process of the most effective means of assessing the extent of coastal wetlands pollution of the marine waste. This work is performed on Oued Loua beach on the Mediterranean Sea in the north of Morocco. This work aims to monitor the presence of marine debris and the impact of fishing activity in the presence of this waste. The results of the process of collecting samples seasonally during the year 2015 show that the area is characterised by the existence of five types of macro debris. The plastic is the more abundance with (53, 05%), following by lumber and paper (35,83%), clothes and fabric(8,47%), Metal (1,89%) and (0,7%). The micro-debris varied between (0-5,2g) and the third season is the more polluted. In order to determine the differences between transects, the analysis of variance Only three variables are significant. Total cigar tips, total pieces of rope and total cups with two significant groups for each variable (P-value<0.05) by Games-Howell multiple comparison. Two variables are significant total personal care products, Total plastic bags (or frag) by Tukey HSD multiple comparison.

Bloody Nipple Discharge Revealing A Bilateral Deficient Streptococcus Infection
Mbongo JA, Opfou Ondongo I, Loubienga S, Yala F, Iloki LH
Authors report a clinical case of bilateral bloody nipple discharge from a woman of advanced age, due to a deficient streptococcus infection. The diagnosis was not easy because of the type of germ that requires a special identification method, and also because of the clinical breast symptoms at this age that more likely suggest breast cancer. More perseverance was needed to finally achieve therapeutic success.
Keywords: nipple discharge - deficient streptococcus.
Classification of Web Pages and Extraction of User Browsing Pattern from Web Log Using Reinforcement Learning
Abdul Rahaman wahab sait and T.Meyyappan
Internet became part of life and billions of website exists in web. Web data is the combination of text, picture, and animation and difficult to extract data from web pages but with limited functionalities. Web page classification (WPC) is a method derived from web mining (WM) to classify web pages according to the label. Web usage mining (WUM) is another method from WM to extract useful patterns from weblog stored in the web server. The pattern extracted by WUM will be useful for the website owners to know the interest of visitors and customize their site depends on the pattern. The proposed research implements Reinforcement learning (RL) method to classify web pages into certain pre – defined categories and mine patterns from the weblog and divides the visitors into different types.

Etude préliminaire du volcanisme permien du massif de Bou Achouch
Abdelaziz BOUTSOUGAME, Hassane OUAZZANI, Hassan EL HADI and Aâtika EDDIF
Permian volcanic Bou Achouch complex (Central Morocco), manifested primarily by volcanic rocks of andesite and rhyolite type, intercalated in the clay-Greso-conglomeratic Permian deposits. These are rocks texture microlitic to porphyritic. Rhyolites show a primary paragenèse formed of plagioclase, biotite, quartz and orthoclase and secondary mineral assemblage consisting of calcite, quartz and oxides. Andesites consist of a primary paragenèse formed of plagioclase, pyroxene and amphibole and a secondary mineral assemblage formed of calcite, quartz and opaque. The rocks were studied petrographic characteristics comparable to those described in the Permian complex Khénifra and Tiddas- Sebt Ait Ikkou (Central Morocco).
The Bou Achouch subject area during the Permian essentially a compressive regime and recorded four episodes of deformation.

Enikuomehin, A.O, Amin A.O, Ogundipe D.A, Enikuomehin, M, Adefokun, A.O and Bashirat A.
Many modern devices for image identification has performed poorly in matching similar faces across different age brackets. This has led to multiple facial registration for a single task. The paper identifies the problem as an issue related to facial image feature extraction and hence propose the combination of the Linear Binary Pattern (LBT) and the Gabor Wavelent Transform (GWT) as a standalone algorithm to enhance the process of facial image retrieval. Several experiments were performed using Age invariant FR data, the combined results shows that the utilization of the mixed LBT and GWT method improved processing time( GWT: 6.1094, LBT:4.36404, HYBRID: 3.6404); false acceptance rate GWT: 25%, LBT:10%, HYBRID: 0%) and False rejection rate(GWT: 15%, LBT:8%, HYBRID:0%). The paper concludes that, for mixed hybrid method performs outstandingly when compared with single phrase bench mark approaches. It further recommends that future commercial and practical systems should incorporate the hybrid approach to achieve actual retrieval by building across age invariant retrieval systems.
