Selma Regina Martins Oliveira and Jorge Lino Alves
The present paper aims to verify the influence of innovation in the product development process on the performance of firm, based on 3D modeling and additive manufacturing (AM), in the perspective of value co-creation. A case study was applied in the (Firm MEDIMAT - Used skull) field of the medical sciences in development of patient-specific maxillofacial prosthesis. The research involved the intervention of experts - multidisciplinary teams, doctors, engineers, manufacturers of prosthesis, selected by technical-scientific criteria. The data were extracted using an assessment matrix. To reduce subjectivity in the results achieved the following methods were used complementarily and in combination: multicriteria analysis, psychometric scaling, Spearman and neurofuzzy technology. The results were satisfactory, validating the submitted proposal, allowing to show that it is possible to combine additive manufacturing techniques, traditional processes of production of components and the incorporation of other components, allowing to develop innovative products in very short time frames, with market acceptance and creating business and client value. The use of additive manufacturing techniques has been effective in the reduction of time of product development, helping identify flaws and improving the final quality of the product, since it is possible to perform repetitive tests, such as building a prototype, testing it, re-designing it, building it and testing it again.

Ataollah Abbasi and S.Hamid Fathi
Ferroresonance can cause severe overvoltages and heavy currents resulting in damage to power system equipment and customer installations. Ferroresonance is a complex phenomenon that occurs in power system. This can create thermal and insulation problems for power system equipments. It can also cause subharmonic oscillations in power system. This paper, discusses about ferroresonance in series compensation of power lines.
Series capacitors can increase the power carrying capacity of subtransmission and distribution lines by reducing voltage regulation. When considering Series capacitor compensation of distribution lines and subtransmission lines careful consideration needs to be given to capacitor location. Ferroresonance, ohmic reactive value, transient behavior, short circuit withstand and capacitor protection conventional design approaches include shunt connected resistors, spark gaps, metal oxide visitors, thyristor controlled reactors and bypass switches. A small scale nonlinear single phase Ferroresonant circuit was modeled with realistic per unit component value. Both 3rd and 2nd subharmonic Ferroresonance modes were predicted by modeling.
Keywords: Series Capacitors, Nonlinear Components, subharmonic Ferroresonance, power transformer.

Tchuigoua Ariane Clarisse, Mezajoug Kenfack Laurette Blandine and Tchana Angele
Defatted flours from Ricinodendron heudelotii and Tetracarpidium conophorum were used for in vivo protein digestibility essays with the aim to evaluate their potential effect on biochemical parameters (glycaemia, serum and hepatic protein concentration, transaminase activities, lipid profile) on 90&plusminus;5days old Wistar male rats. The liver and kidney histology were also performed. Diets made with these flours as protein sources (10%:w/v) were formulated. Casein was used as control. Rats were fed during 16 days and on the 17th day, they were fasted for 12 hrs, sacrificed and their blood collected for biochemical analyses. R. heudelotii (RHDF) and T. conophorum (TCDF) defatted flours contain 66.27-67.08% crude proteins, 11.62 – 48% crude fibres, 8.49-13.92% total ash. In vivo study revealed an increase in body weight of rats with casein compare to those fed with RHDF and TCDF. Compared to casein group, rats from RHDF group showed a decrease in glycaemia of 22.45% (P<0.05). Serum and hepatic proteins levels in rats fed with RHDF diet (97.27mg/g/rat/16days) were different (p<0.05) to those of casein group (89.43mg/g/rat/16days). ALAT value in casein group (32.5UI/l) was similar to that obtained in TCDF group (33.75UI/l), different (p>0.05) to RHDF group (11UI/l). The lowest value of triglyceride (TG) was obtained with RHDF (0.89mmol/l) group compared to those of casein group (1.46mmol/l). HDL cholesterol for experimental diets (0.14 and 0.12mmol/l respectively) was comparable to that of control diet (0.11mmol/l). LDL cholesterol was higher with rats from casein group. The histological section of liver and kidney of rats fed casein and experimental diets presented no cell or membrane lysis.

Environmental Indicators of Oil Companies
Darliane Ribeiro Cunha
Currently, many interest groups demand that the social and environmental aspects be considered as a variable key to understand the performance and strategic position of companies. The objective of the paper is to analyze the disclosure of environmental indicators by oil companies. It is an exploratory and descriptive research. The oil companies publish their sustainability reports and use the environmental indicators of the Global Reporting Initiative. However, the level of the environmental indicators disclosed is not what is expected, nor is there a proactive approach that is conducive to the demands of stakeholders. The results of the study show a moderate disclosure in aspects such as emissions, effluents, waste and biodiversity that are essential for the sector. The oil industry is responsible for a significant share of greenhouse gas emissions, and controlling these emissions is vital to contribute to a low carbon future. In addition, relevant indicators such as materials and energy have a lower disclosure.

Cowpea, Vigna unguiculata (L.) Walp. is an important crop in Benin. Many pest comprising Aphids, Thrips and Maruca constitute bottlenecks to the crop development and growth. This study aims at assessing the efficacy of the cashew’s balms as alternative and ecological methods to control these pests. The study was performed using the cowpea local variety ‘‘TAWA’’ grown at the Agronomic Faculty farm in Benin. Completed Block Design was used with six treatments: untreated; insecticide (LAMBDACE 25EC), cashew’s balms extracted while it is cold from the weaken hull of cashew; cashew’s balms extracted while it is cold from non-weaken hull of cashew; cashew’s balms extracted while it is hot from the weaken hull of cashew; cashew’s balms extracted while it is hot from non-weaken hull of cashew. Ten cowpea plants per plot have been used through the experiment from the flowering. The pests’ density was low in treated plots: the numbers of 50.91&plusminus;18.63aphids; 0.20&plusminus;0.06thrips; 2.16&plusminus;0.61Maruca against 133.58&plusminus;11.02aphids; 0.93&plusminus;0.06thrips; 9.91&plusminus;1.46Maruca respectively for hot extracted from weakened hull of cashew and untreated. Finally, the treatments’ efficacy involved the improvement of grain yield, (P<0.01). These results indicated that the cashew’s balms can be used to control these pests for safe and sustainable cowpea production.

The present study aims at the efficacy of the biocidal property of Tephrosia vogelii in the control of pyrethroid-resistant vectors. Larval tests were carried out on the larvae of stages 2, 3 and 4 of An. gambiae s.s. of wild-type. The susceptible reference strain "Kisumu" served as a control. Mortalities were read 24 hours and 48 hours after exposure. LD 50 and 90 for 24 hours and 48 hours were determined according to the log-probit method of dose determination corresponding to a proportion. The high LD50 determined correspond to stage 3 larvae of wild populations in 24 hours and 48 hours. Low LD50 refer to Stage 2 "Kisumu" larvae. The highest LD90 correspond to stage 3 larvae of wild populations. The weak refer to Stage 4 "Kisumu". The ratios determined indicate a negligible influence of resistance on the bliss of plant extracts. Larvicidal activity of plant extracts at unprivileged doses on larvae of sensitive and wild strains provides an alternative advantage in the management of vector resistance to pyrethroids.

Asma’a Al-Amarneh and Hadeel Yaseen
Financial intermediaries in general and commercial banks in particular, play a crucial role in maintaining economic growth of a nation by facilitating the flow of funds to various sectors of the economy. The efficiency of the banking system is one of the most critical aspects in the financial market, since it affects the stability of the banking industry and thus have a significant impact on the effectiveness of the entire monetary system. The aim of this paper is to analyze the efficiency of the banking system in Jordan and to establish empirical evidence on the impact of economic freedom on bank efficiency during the period of 2005-2015. The efficiency scores of commercial banks are measured by using the Data Envelopment Analysis (DEA), a linear programming technique that was developed by Charnes Cooper (1978) between the years 2005-2015. The findings reported in this paper shows that following the 2008 financial crisis, the increased government intervention had a negative impact on the efficiency of the Jordanian banking sector.
