Industrial biotechnology (IB) is considered a multidisciplinary discipline. Up to date, in Ecuador there is a growing demand from both, academia and industry for scientists with a solid background in the field of bioinformatics, genetic engineering, industrial biotechnology and bioprocesses. This work describes a practical educative example with an integrative approach based on simulation programs that include and relate such important disciplines, which normally are taught as separated courses in our institutions. The participants acquired skills from these disciplines in the same classwork in which they used computer programs to pose and solve a practical problem going from the molecular design to the industrial process through design, economic and environmental analysis of the bioprocess. With these integrated simulations, the student gets closer to the reality of what is done at the industry level. University professors, who teach integrative subjects at the undergraduate level such as Industrial Biotechnology and BioProcess Design & Economics, can use this practical and inspiring educational example highly valued by students supported by computer programs, also thought to be used in postgraduate programs. Satisfaction survey results are also discussed.

La deserción es un tema relevante en las instituciones de educación superior que ha sido muy estudiado por varios autores. El presente trabajo presenta una propuesta muy interesante para la medición de la deserción estudiantil, siendo parte del insumo informativo para la toma de decisiones con la finalidad de revertirla. El uso de este indicador denominado Índice Geométrico de Deserción ha logrado entregar variada información de forma rápida y efectiva. Cuando se analizan los resultados de la deserción, estos indican que los departamentos académicos presentan una tendencia al alza, observándose que la deserción de segundo año es tan alta como la de primer año, lo cual está en contra de un consenso respecto que la deserción de segundo año resultaría ser bastante menor a la de primer año, sobre todo en carreras de tres años de duración. También se observa un menor ingreso del sexo femenino el que presenta una deserción significativa. El grupo de investigación recomienda la utilización de este indicador por tener una metodología bastante eficaz para la producción de información basada en la deserción.

Customer confidence is critical to businesses as customers are reason why organisations remain sustained hence serving them better. Meanwhile, high level of loss of customer confidence is being experienced due to poor strategic leadership which has led to various problems for many Insurance companies in Nigeria. This study investigated the effect of strategic leadership on customer confidence of quoted Insurance companies in Nigeria. The study adopted cross-sectional survey research design. The population was 375 executive directors and executive managers of 20 quoted insurance companies in Nigeria. Total enumeration method was adopted. A structured and validated questionnaire was used to collect data. Cronbach’s Alpha coefficients for all the constructs ranged from 0.71 to 0.82. The response rate was 82.9%. Data collected were analysed using descriptive and inferential (linear and multiple regression) statistics. Findings revealed that strategic leadership had significant effect on customer confidence of quoted insurance companies in Nigeria (Adj. R2 = 0.297; F (5,305) = 27.134, p < 0.05). The study concluded that strategic leadership enhances customer confidence of quoted insurance companies in Nigeria. It was recommended that management of quoted insurance companies in Nigeria should continuously adopt strategic leadership so as to ensure customer confidence and remain sustained.

This paper proposes an integrated inventory model for manufacturer and retailer in order to achieve a long term sustainable supply chain. Aim of the paper is to maximize their individual as well as joint benefit when units ordered by retailer is actually not delivered by supplier. We determine optimal order quantity and number of shipment in integrated and non-integrated scenario when input is random. This model is analysed for time dependent deteriorating items with fix life time. Sensitivity of different inventory and supply chain parameters is carried out using appropriate data. This model is useful to managers for managing supply chain of drugs, cosmetic, FMCGs and many more.

Popularity means the need to love and to be loved and it is one of the human innate needs. Being truly popular means for a person to treat people with good intentions and honest behavior so they can enter people’s hearts and be loved by them. Considering the significance of this issue, knowing what factors lead to an increase in popularity of athletes among their fans could be a key to an increase in their popularity. This research tries to propose a true and real popularity model for athletes. Mixed method is used in this research. The statistical population in this research in qualitative section included experts in three field of soccer, volleyball and wrestling and in the quantitative section included all fans of the three aforementioned fields in Shiraz County(Iran). In the qualitative section, 16 experts were interviewed qualitatively and in the quantitative section, the questionnaire derived from the analysis of the interviews were distributed among 215 fans. Results suggested that fans considered 23 sub-categories in 4 main categories for popularity of the athletes. These four categories included: being committed to beliefs and values, desirable social relationships, being determined and strong-willed, and having dignity.

In this paper, a framework for the synchronization of two discrete hyperchaotic systems, namely the 3D\ngeneralized Hénon maps, based on the use of output feedback concept and aggregation techniques is proposed and\napplied to a two-channel secure communication design. New sufficient conditions for synchronization are obtained by\nthe use of Borne and Gentina practical stability criterion associated to the forced arrow form matrix for system\ndescription. The application of the proposed approach to hyperchaotic Hénon maps, considered as symmetric\nencryption and decryption keys, proves the efficiency of the proposed communication system to confidentially recover\ntransmitted messages. Numerical simulations are carried out to assess the performance and the efficiency of the\nproposed contributions in the important field of secure information encryption.

In this study a novel diazinon biosensor based on Acetylcholinesterase (AChE) immobilized on Sol-IonicLiquid-Graphene (Sol-IL-Gr) nanocomposite modified electrode is reported. The proposed biosensor accelerated the conversion of substrate (acetylthiocholine chloride) to thiocholin which was electrochemically oxidized at 0.6V vs. calomel reference electrode. In order to improve the efficiency of the proposed biosensor the influence of AChE concentration, pH and substrate concentration on the response of the AChE biosensor was investigated. The Sol-IL-Gr nanocomposite modified biosensor showed a wide linear range from 2 to 60 ?M with a detection limit (LOD = 3Sb/S) of 1.8 ?M for diazinon. This biosensor could provide a simple and sensitive method for diazinon detection in real samples through an effective enzyme immobilization on the electrode surface.

Our research is about the use of the whole public expenditure of operations and equipment as an instrument of economic growth. The traditional and new theoretical doctrines which are stated in our work, indicate that the theoretical framework adapted to the treatment of this problematic belongs to the models of the internally formed growth.\nThe aim of our study is to demonstrate the importance of the total expenditure of STATE on the economic growth in Algeria . To attain this we have considered carefully a variety of different patterns which have dealt with this main object. Thanks to Econometric modeling, we came to the point that expenditures have no effect on the economic growth.

Mental health difficulties of traumatic brain injury (TBI) interfere with rehabilitative interventions and following their discharge from inpatient rehabilitation settings. Little is known in Saudi Arabia about how emotion recognition abilities become affected after TBI. The aim of this study was to determine whether emotion recognition deficits may be additional mental health impairment for adolescents with TBI. A case study of five adolescents with TBI at the outpatient rehabilitation psychology clinic at the Rehabilitation Hospital of King Fahad Medical City (KFMC) was conducted. Deficits in recognizing emotion was reported among the sample. The finding highlights the importance of providing valid neuropsychological assessments in order to target emotion recognition limitations in the rehabilitation interventions programs.
