Title: Biosynthesis And Characterization Of Silver Nanoparticles Using Fig (Ficus Carica) Leaves: A Potential Antimicrobial Activity

Abstract:Environmentally friendly methods for obtaining nanomaterials see a great interest. In addition to being inexpensive, the easy implementation process and the advantages of synthesis without toxic chemicals are the main reasons of interest. In this study, silver nanoparticles (AgNPs) were successfully synthesized using fig (Ficus carica) leaf extract. The formation and the presence of AgNPs were observed using ultraviolet-visible spectrophotometry (UV-Vis). Peaks with a maximum wavelength of 419 nm are identified in the measurements. Phytochemicals in the extract responsible for functional groups providing reduction and stability were evaluated using fourier transform infrared spectroscopy (FT-IR) data. The Scanning electron microscopy-Energy Dispersive X-Ray Spectrum (SEM-EDX) analysis showed that the AgNPs were spherical and the elemental composition contained mostly silver. X-ray diffractometer (XRD) results revealed that the peaks 111o, 200 o, 220 o and 311 o belong to the characteristic structure of silver and have a crystal dimension of 17.30 Nm using Debye-Scherrer equation. In thermogravimetric - differential thermal analysis (TGA-DTA) analysis, the degradation temperatures of AgNPs were evaluated. AgNPs showed antimicrobial activity on various microorganisms even at very high concentrations. As a solution to the antimicrobial search, it can be developed in medical industry.

Title: In Vitro Antioxidant and Cytotoxic Activities of AgNP Synthesized By King Oyster (Pleurotus eryngii) Mushrooms On Some Types Of Cancers

Abstract:Synthesizing nanoparticles (NPs) using wild edible fungi with environmentally friendly synthesis methods is more preferred because of the advantages it provides. The fact that its synthesis is easy, economical, non-toxic and has a wide range of uses increases the interest in this subject. The aim of this study was to determine the antioxidant and cytotoxic activity of biomolecularly synthesized Pleurotus eryngii silver nanoparticles (PE-AgNPs) against human prostatecarsinoma (PC-3), human cervix (HeLa) and breast carcinoma (MCF-7) cells. PE-AgNPs showed significant cytotoxic activity against HeLa, PC3, MCF-7 cell lines, and also dimethyl sulfoxide solvents of PE-AgNPs applied for their metal chelating activity, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity and antioxidant activity using the β-carotene linoleate model system. Biosynthetic PE-AgNPs were found to inhibit the proliferation of PC-3, HeLa and MCF-7 cells with IC50 values of 2.185, 46.594 and 6.169 µg / ml, respectively, during a 24-hour incubation period. With the parallel of increasing concentartions (1, 2, 5, 10 mg/mL) the activities were also increased at all the tests studied. At 10 mg/mL antioxidant activities were 82%, 85% and 77% for chelation of ferrous ions reducing power, DPPH scavenging and β-carotene linoleate tests respectively. The results show that PE-AgNPs may contribute to the development of a suitable anticancer drug that can lead to a new development of nanoparticles for cancer treatment. It also appears to be advantageous to use nanotechnology and green chemistry to improve the existing therapeutic properties of P. eryngii.




Title: PERCEPTION OF NURSES ON THE FACTORS ASSOCIATED WITH PREGNANCY IN ADOLESCENCE

Abstract:In Brazil, in the last decades, the proportion of deliveries performed among adolescents is increasing. It is observed that even with the reduction of the fertility rate in the 70\'s, the number of pregnancies in adolescence has increased greatly in recent years. Thus, this study aimed to identify the main factors associated with pregnancy in adolescents according to the nurses\' perception. This is a qualitative study with a descriptive approach, developed in the Family Health Strategy of a Brazilian municipality. Five nurses participated in the study. A semi-structured script was used to collect the data and, for the analysis of participants\' discourses, the Content Analysis technique was used. It was evidenced that the main factors associated with the high number of pregnant adolescents in the municipality are low income, lack of information about sexuality and fertilization, inadequate use of knowledge about contraception, mainly on the use of contraceptives and condoms.




Title: ERECTION OF THE KNOWLEDGE ECONOMY: A STRONG DEVELOPMENT POTENTIAL FOR INDUSTRIALIZED COUNTRIES AND A PERSPECTIVE FOR DEVELOPING COUNTRIES

Abstract:The paper provides a diagnosis of the fragile position of developing countries in the knowledge economy and proposes recommendations to enhance it. The paper opted for: to measure the intensity of the contribution of knowledge to the economic performance of developing countries, a Knowledge Economy Index (KEI) has been developed to classify industries according to the knowledge content (high, medium and low). We present a number of theoretical, making use of econometric techniques developed to justify the role of knowledge production and ownership of skills in the development of activities that generate high added value. We constated that: The Knowledge Economy Index (KEI) follows the following form: ??EI??(Developing Countries)=0.43*HK+0.16*(R&D)+0.43*TFP ??EI??(Industrialized Countries)=0.32*HK+0.30*(R&D)+0.38*TFP The success of a strategy of building the knowledge economy will depend on a number of conditions which require, among other things, a deepening of reforms to the pillars of economy, development of a modern infrastructure science and technology, skills development and intensification of scientific research, a favorable regulatory framework for economic and technological change and respect the rules of intellectual property.

Title: Description of convective drying of carrot circular slices including shrinkage and variation of effective diffusivity

Abstract:In this work, circular slices of carrots were dried at temperatures of 40, 50, 60 and 70 °C. The carrot slices were cut with average thickness of 4.5 mm. A numerical solution was proposed for the diffusion equation in Cartesian coordinates (one-dimensional case), in order to describe the drying process. The diffusion equation was discretized assuming the variation of the effective diffusivity and the thickness of the slices. Six empirical equations found in the literature were analyzed to study the drying rate. A period of induction was observed at the four temperatures studied. These periods were considerable, especially at temperatures of 40 and 50 °C. The proposed diffusive model described well the periods of decreasing rate, with good statistical indicators for all fits.
