Renata Vianna Lima, Henrique Duarte Vieira, Francielle de Souza Guimar?es, Nardele Moreno Rohem Jr., Tatiana Oliveira da Silva, Alberto Magno Fernandes, Cynthia Pires Guimar?es, Amanda Justino Acha, Bruno Borges Deminicis
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.514230
Abstract:

This study was conducted to evaluate the physiological quality of forage seeds after passage through the gastrointestinal tract of cattle, as well as the emergence of seedlings derived from these seeds. Three Fabaceae species were used: tropical kudzu, leucaena and calopo. One hundred grams of seeds of each species were offered, separately, to five bovines. After the start of the dispersion, the faeces of the animals were collected every 6 hours, in a total of 72 hours, being taken to the greenhouse immediately after each collection. The study evaluated the total number of seedlings in the stool, the lengths of roots and aerial parts, as well as the natural and dry seedling weight thirty days after the disposal of the faeces in the greenhouse. The experimental design consisted of randomized blocks, with twelve treatments (sampling periods) and five replications (cattle). The best performance for the total number of seedlings in the faeces of cattle was observed in the kudzu species. The length of the root, length of the aerial part and dry matter seedling weight was observed in the leucaena species, followed by kudzu. The calopo showed low results for all variables due to the high degradation of the seeds.

BENEFITS AND SUCCESS FACTORS OF OPEN-SOURCE WEB SERVICES DEVELOPMENT PLATFORMS FOR SMALL SOFTWARE HOUSES
Valter de Assis Moreno Jr.
JISTEM - Journal of Information Systems and Technology Management , 2012,
Abstract: It is usually difficult for companies to keep up with the development of new information technologies and adapt to them in face of the opportunities and threats their advances may represent. This is especially true for small and medium enterprises (SME) in emerging economies, where resources tend to be scarce and markets more volatile. This paper describes an action research conducted in a small Brazilian software house that adopted an open-source Web Services development platform in order to improve its software development process. Data analysis revealed critical success factors (CSF) in the adoption process, as well as specific benefits and barriers prone to be faced by small software houses in their adoption efforts. In the process of overcoming such barriers, SME may acquire intellectual capital that represents an essential resource to ensure their competitiveness and survival in emerging economies.

Journal of Cancer Therapy (JCT) , 2013, DOI: 10.4236/jct.2013.47A009
Abstract:

Cancer is a leading cause of death worldwide, and is estimated to be the cause of 13.1 million deaths in 2030. Breast cancer is the second cancer in the global mortality ranking, considering both sexes. Due to the burden of breast cancer worldwide, this paper aims to present an overview of the main R&D efforts focusing on breast cancer treatment. Patents were retrieved from the Derwent Innovations Index?, which has a specific code for pharmaceuticals related to breast cancer. A total of 423 patent documents filed in recent years were identified, of which 126 are exclusively for breast cancer, 169 for breast cancer and other cancers, and 128 are inventions related to the treatment of cancer and other diseases. The patent documents were classified into two large groups, the first of which had a predominance of claims for antibodies, proteins and polypeptides for use in medication production, while the second focuses on gene therapy, nucleotides and RNA. The country with the majority of priority patent applications was found to be the United States, followed by China and Japan.

Abstract: diversity and biomass of chironomidae larvae were studied between january-november 1993 and march-november 1994 in an impacted lagoon in rio de janeiro, southeastern brazil, in an attempt to establish the ecological consequences of anthropogenic eutrophication processes. nine hundred and seventy-five organisms belonging to the tanypodinae, orthocladiinae, and chironominae were collected. polypedilum (62%) and chironomus (58%) were the most common genera found in the limnetic and littoral zones.
Malacological assessment and natural infestation of Biomphalaria straminea (Dunker, 1848) by Schistosoma mansoni (Sambon, 1907) and Chaetogaster limnaei (K. von Baer, 1827) in an urban eutrophic watershed
Callisto, M.;Moreno, P.;Gon?alves, J. F. Jr.;Ferreira, W. R.;Gomes, C. L. Z.;
Brazilian Journal of Biology , 2005, DOI: 10.1590/S1519-69842005000200005
Abstract: the objective of this study was to perform a malacological assessment at the ibirité reservoir watershed in the metropolitan region of belo horizonte (minas gerais) and to evaluate the natural infestation rate of biomphalaria straminea (gastropoda: planorbidae)by schistosoma mansoni (platyhelminthes: trematoda) and chaetogaster limnaei (oligochaeta: naididae). the samples were collected from july to august 2002. the b. straminea individuals collected were kept in the laboratory; the natural infestation rate by s. mansoni and c. limnaei was assessed weekly. the malacological assessment identified fivemollusk species present in the ibirité reservoir watershed: b. straminea, physa marmorata, lymnea sp., melanoides tuberculatus,and pomacea austrum. laboratory observations showed that the b. straminea individuals were infected by c. limnaei rather than s. mansoni. although there was no infection of b. straminea by s. mansoni,presence of b. straminea in itself merits close attention due to possible risk of human schistosomiasis by the local population.

JISTEM - Journal of Information Systems and Technology Management , 2009,
Abstract: This study investigates work relations and career perspectives of IT professionals in the information technology service industry. The research is based on the case of executives, managers and technical professionals which work in a large Brazilian company that provides consulting and systems development and implementation services, and reveals a considerable vulnerability in the relationship between the company and such professionals. The human resources business model adopted seems to impose restrictions to the development of the professionals, consequently limiting their future performance, and concurring for the continuing devaluation of IT as a profession. The sustainability of such a model is discussed, given its long term risks for the companies’ service quality and competitiveness, as well as its implications for the attractiveness of Information Technology as a career.

Magnetic dilution on LaCrO$_3$
Romualdo S. Silva Jr.,Petrucio Barrozo,N. O. Moreno,J. Albino Aguiar
Physics , 2015,
Abstract: In this work, we study the effect of the magnetic dilution of Cr$^{3+}$ on the LaCrO$_3$ half doped with Al. Pure and half-doped samples were prepared by combustion method using urea as fuel. The crystal structure was investigated by X-ray diffraction. Rietveld analysis reveal a structural phase transition caused by the increase of the chemical pressure due difference of Al$^{3+}$ and Cr$^{3+}$ ionic radii. SEM images shows that the samples exhibit a spherical formation and irregular morphologies. Magnetization measurements as a function of temperature reveal an antiferromagnetic order in both samples with a large decrease of T$_N$ (N\'eel temperature) with Al doping. The reduction of frustration factor and the increase of the magnetic moment of the doped sample could be attributed to the breaking of the long-range antiferromagnetic order. The magnetic hysteresis loops show a typical antiferromagnetic behavior with a slightly spin canting for the doped sample.
