Published: March 2018

At present, the analysis of the results of advertising and marketing studies is done qualitatively in terms of the experience of a marketing analyst, thus generating little certainty and uncertainty of the effectiveness of the feelings and the message emitted. Brands are connected with the idea that the sender wants to transmit. For this, the marketing has studied the behavior of the consumer when exposed to different advertising stimuli, in order to understand the behavior at the time of the stimulus and to achieve alignment of the message to be transmitted with what is actually perceived. In this paper we propose a vector model based on computational intelligence and Neuromarketing studies that allows the identification of four basic emotions: joy, fear, anger and sadness from the bioelectric brain activity recorded by a person exposed to a certain audiovisual advertising. The results of the model allowed the identification of emotions in audiovisual advertising, which constitutes a tool that allows companies to create audiovisual advertising that guarantees greater commitment and effectiveness of the advertising segments with which it wants to impact the marketKeywords: Neuromarketing, audiovisual advertising, basic emotions, neural networks, Emotiv-EPOC®, vector support machines

In Panama, there are community organizations that guarantee access to water for human consumption to more than 20% of the country's total population. For the sustainability of the water resource, it is essential to involve the communities in the process of monitoring the water quality. This can be achieved through the implementation of participatory biomonitoring using macroinvertebrates as indicators. In fact, it has been determined that the presence of different families of these organisms in ecosystems can be associated to different levels of their ecological quality. This work aims to develop a system capable of recognizing two families of macroinvertebrates through the use of images. The system is based on the use of algorithms of deep neural networks, with which we can achieve the learning of patterns. From a set of public images from the internet and biomonitoring carried out in the field, we train a convolutional neural network implemented in Tensorflow and Keras. These images belong to photographs of specimens of the families Calopterygidae and Heptageniidae. For this preliminary test, we report reliability percentages with values above 95%.Keywords: image recognition, neural networks, convolutional neural networks, macroinvertebrates
Reduccion de CO2 por el Uso de Lamparas de Bajo Consumo a Expensas de la Generacion de Residuos Peligrosos Domiciliarios

Published: March 2018

Because the national legislation prohibits the sale of incandescent lamps the argentine citizen can acquire compact fluorescent lamps in their replacement. This situation has led us to develop this work whose main objective is to establish a comparison between these two types of lamps from the energy point of view and its environmental consequences. To this end, we have developed a study based on the last national census in Argentina. While significant energy savings achieved, and as a result lower emissions of carbon dioxide, this leads to an environmental problem due to the mercury content of compact fluorescent lamps. They become in hazardous waste when exhausted their useful lives and are discarded in sites for municipal solid waste. High probability that the lamps are broken and release mercury that can contaminate 19,55 liters of drinking water for kilogram of CO2 saved. We conclude that the regulations required to purchase compact fluorescent lamps instead of traditional incandescent lamps must go accompanied with sustainable alternatives to dispose them appropriately since otherwise we will be replacing an environmental problem with another.

Published: March 2018

Rotating electric machines with operating voltage greater than 12 [kV] are an integral part of the installed base of electric generators in different countries. These voltages incorporate new challenges to be solved in maintenance practices. One of the most important challenges is the identification of the condition of the stator winding. For many years, the most commonly used monitoring techniques in electrical generators were off-line insulation measurements, especially in direct current. More recently, the use of on-line insulation monitoring techniques has enabled problems to be detected in advance, such as partial discharge measurement. This article presents the measurement of on-line partial discharges, as a condition monitoring technique for high voltage electric generators. It is also used for risk assessment and decision support for corrective actions. In the case study, it was evidenced that periodic monitoring is key during the operating time of the evaluated generator unit, which can be extended to other generators. The monitoring of on-line partial discharges allowed to know its condition and evolution through the trend in time.Keywords: Partial discharge, electric generator, failure mode, predictive maintenance, void.
Experimental Study of a natural ventilation strategy in a Full-Scale Enclosure Under Meteorological Conditions: A Buoyancy-Driven Approach
Authors: Austin Miguel Chen , Bruneau Denis , Sempey Alain , Mora Laurent , Sommier Alain
Published: March 2018

The performance of a natural ventilation strategy, in a full-scale enclosure under meteorological conditions is studied through an experimental study, a buoyancy-driven approach, by means of the estimation of the air exchange rate per hour and ventilation power. A theoretical and an empirical model are proposed based on the airflow theory in buildings and blower-door tests. A preliminary validation, by comparing our results with standards in air leakage rate determination, is made. The experimental study conducted here has shown that the natural ventilation strategy implemented reach promising air exchange rate levels, as they are rather high compared to other experimental studies found in the literature.  The proposed models have shown good potential and further analysis should take place. Also, other methods for validating these models should be implemented (for instants: CFD simulation or tracer gas methods), as the one in the standards is rather rough estimations.Keywords: Buoyancy-driven, natural ventilation, ventilation power, blower-door test, airflow in buildings.

Published: March 2018

This study deals with the estimation of the carbon associated to the Above Ground Biomass, in a permanent plot of measurement located in the Cerro Pelado Tropical Hydrology Observatory in Gamboa, Panama. The objective is to highlight the contribution made by one-hectare of this forest to the local Climate Change mitigation. We employed a relation to carbon storage and sequestration, based on the important species of the tree community with diameter at breast height equal to or greater than 10 cm. It was found an increase in the Above Ground Biomass at the plot, with values of: 193 Mg*ha-1, 218 Mg*ha-11 and 225 Mg*ha-1, for the 2008, 2012 and 2015 censuses, respectively. The net growth in Above Ground Biomass is eliminating approximately 7 to 8 Mg de CO2*ha-1year-1 from the atmosphere, which means that it is acting as a sink and sequestrator of CO2. In this habitat, it is recognizable the important contribution of the Pera arborea species in terms of sustaining carbon sequestration in the Above Ground Biomass.Keywords: Gamboa, Panama, Above Ground Biomass, Climate Change, CO2

Published: March 2018

In the present work we evaluated the use of dolomite as an alternative for the adsorption of lead and copper ions from their aqueous solutions. The possible interferences between them and the selectivity of the process were studied working with mixtures of these two ions in adsorption processes. From the analysis of the results it can be inferred that the adsorption of lead is not affected by the presence of copper, since no changes in its adsorption capacity are observed as the concentration of the other ion changes. Copper adsorption is not affected by the presence of lead up to a copper level of 130 mg / L. For higher concentrations of copper, the antagonistic competition of Pb is manifested. From the kinetic studies performed at an equimolar concentration of Pb (400 mg / L) and Cu (130 mg / L), it was observed that the presence of copper increases the time required to reach the equilibrium of lead adsorption, but its adsorption capacity is unchanged. For the adsorption of copper the equilibrium time was not modified by the presence of lead.Keywords: Competitive adsorption, binary mixtures, copper, lead.

Occupancy profiles modelling based on Indoor Measurements and Clustering Analysis: Application in an Office Building
Authors: Mora Dafni , De Simone Marilena , Fajilla Gianmarco , Fábrega José R.
Published: March 2018

Sensors were applied in an office building to obtain information regarding user presence and absence intervals. Occupancy was also recorded by manual observation, and indoor parameters such as air temperature, relative humidity, carbon dioxide (CO2), volatile organic compounds (VOC) were monitored. Occupants’ behaviors regarding door/window (open/closed) and electric power were considered.  Clustering analysis by manual observation was employed to identify similarities in daily or monthly occupancy and to describe possible occupancy profiles. Similar approach was carried out with each monitored parameter and the results of clustering elaboration were compared with the real occupancy profiles to identify which sensor is more effective to measure office occupancy. Furthermore, data were analyzed to explore relationships between occupancy and the magnitude of indoor environmental changes with the objective to identify daily, weekly, or monthly patterns.  Single-linkage, complete-linkage, and average-linkage clustering were applied to each dataset. The cophenetic correlation coefficient was used to verify the quality of the results obtained for each variable, and the complete linkage was selected to define the groups. Comparison between occupancy real data clustering and VOC and open/closed door groups demonstrated not similarities. The electricity consumption and CO2 data showed some similarities.Keywords: Occupancy detection, environmental sensor, clustering analysis, Office buildings

Published: March 2018

Among the methods used in structural health monitoring (SHM), the electromechanical impedance technique (EMI), which uses piezoelectric transducers of lead zirconate titanate (PZT), stands out for its low cost. This paper presents a new approach for monitoring of the dressing operation based on structural health monitoring from the digital processing of voltage signals based on the time-domain response of a PZT transducer by EMI method. Experimental tests of the dressing process were performed by using a single-point dresser equipped with a natural diamond. The voltage signals in the time-domain were collected in different damage levels using a measurements EMI System. By using damage metrics, it was possible to qualify different damage levels that the diamond suffered during the dressing operation, observing variations from the magnitude of the signals. The dressing operation is of utmost importance for the grinding process and the dresser wear negatively affects the result of the process, which owns high added value. In this way, this work contributes with a new monitoring tool which aims ensuring a consistent dressing operation.Keywords: Manufacturing process, automation, electromechanical impedance, dressing operation.

Authors: Al-Hammad Nouf S. , Al-Dhubaiban Mohammed , Alhowaish Latifa , Bello Lanre L.
Published: March 2018

Objective: To evaluate molar-incisor-hypomineralization (MIH) prevalence, clinical characteristics, and severity amongst school children in Riyadh, Saudi Arabia.
Subjects and Methods: Randomly selected, healthy third- and fourth-grade students (aged 8–10 years) attending elementary schools in Riyadh, and children of the same age attending dental clinics at the College of Dentistry, King Saud University, were examined for the presence of MIH, its clinical characteristics, and severity.
Results: The sample studied consisted of 924 children, 447 (48.4%) of whom were boys. There were 376 children, (199 females and 177 males), with at least 2 index teeth affected (prevalence = 40.7%). A total of 133 (35.4%) had only molar hypomineralization (MH), whereas 243 (64.6%) had molars and incisors involved (MIH). The mean number of affected teeth per child was 6.6 ±3.6 (3.3 for molars and 3.2 for incisors). The chi-Square test showed no association between the distribution of hypomineralization and age (P = 0.115). Children with severe hypomineralization predominated across all age groups, with the 10-year-old group having more severely affected children (71.9%)  compared to 8- and 9-year-old groups (P = 0.000).  Proportional t-test showed no statistically significant difference (P>0.05) between males and females in the occurrence of MH or MIH, and in the severity of the hypomineralization. Upper molars were more affected than lower molars, whilst upper incisors were more affected than lower incisors.
Conclusion: Enamel hypomineralization is a common feature in the dentition of 8–10-year-old children in Riyadh, Saudi Arabia. There is no association with age and no gender predilection.

Authors: Mishra Dr. Vishal , Singh Dr. Alok Pratap , Singh Dr. Lal Mani
Published: March 2018

Introduction : Urinary tract infection is a common contagion among men and women but incidence is quite high among women due to their anatomy. The incidence of the infection is higher among sexually active women and the possibilities of encountering the infection after a sexual intercourse is higher. Identified risk factors for such infections include sexual activity, spermicide-based contraception, delayed postcoital micturition, and a history of previous UTIs.

OBJECTIVES :

To assess socio demographic factors among patients of urinary tract infection.

To assess risk factors contributing to urinary tract infection.

Material and methods :

Total 91 female patients, who were diagnosed to have urinary tract infection were selected in our study. Data regarding socio-demographic and various risk factors was collected and frequency distribution tables were prepared.

RESULTS : Majority females (68%) were between 18-45 years old. About 64% patients belonged to rural area, and 90% patients belong to lower, or lower middle class. About 68% patient’s education was below high school and about 74% patients were married. Among risk factors for UTI, we found that sexual activity (in 83%) was most common risk factor for UTI.

CONCLUSION: Patient who are exposed to risk factors, should be given special attention by the visiting clinicians, so that early diagnosis can be made and early treatment can be started. Early diagnosis and treatment leads to less complications, morbidities and mortality.

Published: March 2018

The present study investigates the relations between obesity and survival during intra-abdominal hypertension (IAH) in diet induced obesity Wistar rats. The animals from model group were fed with high-fat diet for 45 days. Intra-abdominal pressure in both groups (control and model) was elevated by manual system for air insufflations. The pressure was of value (25mmHg) corresponding to the typical values observed in abdominal compartment syndrome. Quantification of the serum levels of serum amyloid A was carried out after deflation. The results interpretation was made in correlation with clinical observations in patients with proved cardiovascular diseases caused by obesity, as well as with patients to whom surgery had caused an increased intra-abdominal pressure. Experimental observations have shown increased survival in diet induced obesity rats with IAH compared to control rats with IAH. Increased resistance to IAH is due to changes in the structure and in the mechanical characteristics of the abdominal wall, following obesity.

Authors: Elgue Patiño Mara
Published: March 2018

Este artículo sintetiza una investigación que se propuso conocer las percepciones de los profesores de Educación Media Superior sobre la evaluación en un contexto de innovación curricular. El nuevo sistema propone evolucionar de un modelo finalista centrado en el examen hacia una evaluación de procesos. La evaluación es uno de los procesos que reviste mayor interés en los cambios. Implica corregir y transformar las tareas de gestionar, enseñar y aprender. Cualquier cambio curricular, está íntimamente vinculado con el profesor en tanto hacedor del currículo en acción. Por ello importan sus opiniones y creencias implícitas para ver lo que efectivamente hacen a la hora de evaluar. Entre las principales conclusiones, se señala que las prácticas de evaluación centradas en la función social de la acreditación han primado en detrimento de la función reorientadora de los aprendizajes y de las prácticas de enseñanza.

Authors: Beese Rebecca J. , Ringdahl Deborah
Published: March 2018

Addressing spirituality in health care is important as it improves health outcomes; however, several provider barriers exist to providing spiritually based care.

A chart audit at a multidisciplinary wellness center serving a population with chronic mental health problems identified a need to improve the number of spiritually based interventions provided to clients by the nurse practitioner.

A quasi-experimental design and pre- and post-test questionnaire were used to measure outcomes including the number of spiritually based interventions and provider attitudes.

Providers, including a nutritionist, exercise physiologist, pharmacist, acupuncturist, and nurse practitioner, participated in two, 1-hour interactive educational sessions on providing spiritually based care, emphasizing the use of gratitude practices.

The mean number of spiritually based interventions charted per visit by the nurse practitioner increased from 0.4 pre-implementation to 1.1 post-implementation (rate ratio = 2.57, with 95% CI [1.75, 3.87]; p < .001). Descriptive statistics from all providers show improvements in attitudes and comfort level in addressing spiritually based care. Several intervention areas documented by the nurse practitioner decreased significantly, including mind/body, which may be related to the study, as many spiritually based interventions are also mind/body interventions.

Interactive educational sessions on spirituality can improve a health-care team's attitudes, comfort level, and practice of providing spiritually based care. Generalizability is limited to the project site, but the process could be implemented in other facilities to determine if similar results can be achieved.
The Impact of Caring: Teaching Students Empathy through the Patient Voice

Published: March 2018

The purpose of this educational brief is to describe an innovative learning experience focused on teaching students empathy for chronic illness, using patient voices. Panel members of individuals who had experienced acute and chronic illness from either the perspective of the patient or caregiver participated in a one-time session for undergraduate baccalaureate nursing students. Panel members presented their narrative to the students, engaging them in a question-and-answer session about the impact of nursing care on their experience. Both the panelists and the students found the experience meaningful. Over time the panel has varied in format, Put has consistently humanized the patient experience, highlighted the importance of empathy and conveyed the impact that nurses have on their patients and families. This innovative strategy proved to be very beneficial for students transitioning into their first clinical experience.

Authors: Vaughan Karolyn , McMurray Anne , Sidebotham Mary , Gamble Jennifer
Published: March 2018

Background:

Certification as a lactation consultant is based on practitioners having achieved a standard of knowledge indicative of their competence to practice by passing a psychometric examination. The underpinning principle of recertification programs is to support clinicians to become lifelong learners by progressively enhancing and advancing their knowledge and skills in line with contemporary evidence. The aim of this study was to investigate the factors that influence International Board Certified Lactation Consultants (IBCLCs) to advance their practice.

Method:

A mixed-methods study was conducted in two phases. Phase 1 included focus groups, interviews, and participants’ demographic data. Phase 2 comprised of an online questionnaire to IBCLCs. This approach was designed to provide a comprehensive qualitative understanding of the IBCLCs’ experiences, which was then triangulated with quantitative data from a significantly larger population of IBCLCs in Phase 2.

Results:

The findings are described in themes and subthemes. Participants in phase 2 (n = 3,946) reported being intrinsically motivated (93.3%, n = 3,631) and committed to providing evidence-based guidance and optimal care to support breastfeeding mothers. They identified various sources of continuing education, although attendance at conferences, peer support, and reflective sessions were the most common approaches to enhancing knowledge. They recognized that it was through extension of knowledge that they were able to advance their practice.

Conclusion:

This article identifies strategies that the managers, educators, and certification bodies can adopt to support the IBCLCs in continuing to advance their practice, which will ultimately improve breastfeeding outcomes for mothers.
The Mystery of D-MER: What Can Hormonal Research Tell Us About Dysphoric Milk-Ejection Reflex?
Authors: Uvnas-Moberg Kerstin , Kendall-Tackett Kathleen
Published: March 2018

The hormones that support breastfeeding also help mothers tolerate, or even enjoy it. But what happens when the hormones of breastfeeding turn against mothers? What if these very hormones make breastfeeding intolerable by biological mistake? That appears to be the case with D-MER. D-MER refers to Dysphoric Milk-Ejection Reflex, where mothers experience dysphoria during milk ejection. D-MER can range from mild to severe. It is a burst of negative emotions in the first few minutes of breastfeeding. In some cases, D-MER is so severe that mothers feel forced to wean. In this article, we examine the phenomenon of D-MER in the light of hormonal research, offer some hypotheses on the causes of D-MER, and suggest possible strategies mothers can use to help them cope.

Synthesis of N-(4t-buthylbenzoyl)-p-aminophenol has been done by reacting p-aminophenol and 4-tert- buthylbenzoyl chloride compounds with 1% MgF2 catalyst. N-(4t-buthylbenzoyl)-p- aminophenol as an antiinflamatory analgesic. Products were characterized by organoleptic test, melting point determination, TLC, UV/Vis Spectrophotometry, and infrared spectrophotometry. The results of the organoleptic test showed that N- (4t-butylbenzoyl) -p- aminophenol is powdered, gray and tasteless. Melting point of N-(4t- buthylbenzoyl)-p- aminophenol was 193 – 194 °C. TLC results showed that N-(4t-buthylbenzoyl)-p- aminophenol had two Rf values of 0.73 – 0.76 and 0.89 – 0.91. The results of UV wavelength scanning showed that N- (4t-butylbenzoyl) -p-aminophenol had two peaks at 290 and 294 wavelengths. Yield of N-4t- butylbenzoyl-p-aminophenol was 24.35%.

Biomass Energy Outlook in Malaysia using Functions of Innovation Systems
Authors: Nyakuma Bemgba Bevan
Published: March 2018

Malaysia generates significant quantities of Oil Palm Wastes (OPW) which can be potentially valorised into sustainable bioenergy as envisaged by the National Biomass Strategy (NBS-2020). Despite significant investments, policy directives and government support, the valorisation of OPW into bioenergy has remained low exacerbating waste management challenges. Therefore, the strategies and impediments to the rapid bioenergy development and bioelectricity generation from OPW require practical assessment. Therefore, this paper examines the level of development and diffusion of the biomass innovation system in Malaysia based on the Functions of Innovations Systems (FIS) approach developed by Dutch and Swedish researchers. Furthermore, the key factors hindering biomass energy technologies implementation in Malaysia and potential solutions were identified, highlighted and examined. Based on the FIS analysis the functions; entrepreneurial activities, knowledge development, and resources mobilization functions are well established in the Malaysian biomass innovation system (BIS). However, the functions of guidance of search; creation of legitimacy; knowledge diffusion and market formation are underdeveloped resulting in the low penetration of bioenergy in Malaysia. Other factors include; fossil fuel subsidies, numerous or conflicting energy policies and weak collaboration between academia and the industry. The outlined challenges can be addressed by revising fuel subsidies, Feed-in tariffs, RETs implementation, roles of supervisory agencies, and bureaucratic procedures for access to funds for research and development of bioenergy in Malaysia.
Optical Conductivity on Charge Order Transition in Organic Dirac Electron System α-(BEDT-TTF)2I3

Published: March 2018

The optical conductivity in the charge order phase is calculated in the extended Hubbard model describing an organic Dirac electron system α-(BEDT-TTF)2I3 using the mean field theory and the Nakano-Kubo formula. A peak structure due to interband excitation being characteristic in two-dimensional Dirac electron system is found above the charge order gap. It is shown that the peak structure originates from the Van Hove singularities of the conduction and valence bands, where those singularities are located at a saddle point between two Dirac cones in momentum space. The frequency of the peak structure exhibits drastic change in the vicinity of the charge order transition.
