Development and Calibration of Method for Thermal Property Measurement of Nonhomogeneous Masonry Materials
Authors: Sanders John P. , Huygen Nathaniel C. , Smith Stephen K.
Published: September 2018

Existing thermal conductivity or R-value data for masonry building materials are very limited and quite dated. Additionally, very little data on heat capacity are available. A convective heat transfer device was designed and built for the purpose of measuring the thermal performance of nonhomogeneous masonry materials that are not well suited for other testing methods. The device is similar to the hot box apparatus described in the standard ASTM C1363, Standard Test Method for Thermal Performance of Building Materials and Envelope Assemblies by Means of a Hot Box Apparatus, and it uses heat flux sensors to measure heat flows. This modified hot box apparatus is capable of measuring steady-state properties such as thermal conductivity or R-value. The modified hot box can also measure non-steady-state heat capacity that is traditionally measured by laser/light flash apparatuses. The heat capacity measurements can be used to calculate the thermal diffusivity when the density and thermal conductivity are known. The modified hot box instrumentation was calibrated to acquire data on building materials such as brick, concrete, and other nonhomogeneous materials that were large in size and mass.
The Evolution of Stone Masonry Veneer Requirements: Past, Present, and Future
Authors: Civitillo John M. , Peterson J. Eric
Published: September 2018

Stone masonry has been one of the most durable and reliable building materials for thousands of years. Numerous stone structures still stand after centuries of dependable service and resistance to the elements. It has not been until recent history (the last 50 years) that the design and construction of masonry structures has been codified by building officials to impose minimum requirements for the performance of such construction. However, the evolution of modern building codes has resulted in a narrowing of options for constructing stone masonry veneer walls, and the current codes impose significant limitations in the prescriptive requirements for stone masonry veneer, which are often in conflict with industry recommendations and common construction practices. This forces many designers to rely solely upon engineering judgment for the design and construction of many commonly accepted stone masonry veneer wall systems. This paper explores the progression of code requirements for stone masonry from different, and sometimes conflicting, code bodies in the United States through the consolidation of the codes in the current International Building Code. It will also explore the suggested current direction of the masonry industry for expanding the code to include new allowable types, materials, and configurations of stone masonry veneer systems to provide codified requirements for designers to utilize stone masonry more frequently in the design of buildings and other structures.
Evaluation of Existing Moisture Content in Brick for Hygrothermal Models in the Rehabilitation of Mass Masonry Walls
Authors: Cyphers Rex A. , Cyphers Annette M. , Knorowski Jodi M. , Skertic Ashley M.
Published: September 2018

A research study was undertaken to evaluate an in situ test method for determining the existing moisture content of brick masonry for use in hygrothermal models. Currently, ASTM E3069, Standard Guide for Evaluation and Rehabilitation of Mass Masonry Walls for Changes to Thermal and Moisture Properties of the Wall [1], is one of the only industry references providing guidance for evaluating the existing moisture content of masonry materials in buildings when the addition of insulation or other changes to the wall assembly are being considered. When interior insulation or a continuous air barrier is considered for addition to mass masonry walls to meet new energy standards, understanding the properties of the brick, the condition of the wall, and the existing moisture content of the brick are imperative for evaluating the hygrothermal performance of the wall assembly. The assumptions made for the initial moisture content of materials in the hygrothermal models for a mass masonry wall can change the design and alteration approach and, in some cases, could lead to a repair that would have detrimental long-term effects. In the laboratory, the interstitial relative humidity within the brick was measured utilizing temperature and humidity probes embedded within the brick body. The moisture content of the brick was measured at various humidity levels and then compared to various published isotherm curves. In addition to the laboratory testing, field-testing was conducted at five historic buildings with mass masonry wall assemblies to assess the moisture content of the masonry utilizing the same methods as were used for the laboratory testing. When within the hygroscopic range, these methods could be used as minimally invasive and direct techniques to measure the existing moisture content of the brick to develop more accurate and situationally specific hygrothermal models when evaluating existing mass masonry walls prior to a renovation.
Addressing Maximum Design Deflection for Cold-Formed Steel Framing When Used as a Backing for Brick Veneer
Authors: Clark Charles B. , Fried Cortney L. , Bryja James
Published: September 2018

Through the years, different values have been recommended as the maximum deflection for the design of cold-formed steel framing when used as a backing for brick veneer. The basis for each of these recommendations varied considerably and included criteria such as limiting the extent of cracking in the veneer, limiting the width of cracks in the veneer, limiting moisture intrusion, and “observations, experience, and judgment.” The methods by which this information was determined also varied and included analysis, full-scale testing, and field surveys. In addition, the building code-mandated wind load provisions that were frequently used to calculate maximum design deflection have changed over time. This paper reviews and reassesses the different maximum deflection recommendations by examining their basis and other factors. A comparison of the different maximum deflection recommendations is made considering the impact of the changing wind load provisions. Based on this information, a revised approach for determining maximum deflection for cold-formed steel framing used as a backing for brick veneer is recommended.
Cortázar y la formación de palabras. A propósito de las mancuspias
Authors: González García Luis
Published: September 2018

El objetivo de este trabajo es estudiar una de las creaciones léxicas más conocidas de Julio Cortázar, la palabra mancuspia, que designa a unas misteriosas criaturas fantásticas aparecidas en su cuento “Cefalea”(Bestiario). Para ello, después de encuadrarla en el marco general de creación de nuevas palabras propuesto por Cortázar para la renovación del léxico literario (el conocido glíglico, otras lenguas de creación propia como la fortrán) y de ponerla en relación con otros términos surgidos también de la pluma de Cortázar (como el conocido cronopio y otros de la misma naturaleza) concluimos que hay razones para postular que nos hallamos ante un vocablo procedente del gallego, llegado a Argentina como otras muchas palabras en boca de los emigrantes, al que habría tenido acceso Cortázar de manera indirecta. Para justificar esta aserción ofrecemos la documentación, oral y escrita, de que disponemos en gallego (fuentes lexicográficas y muestras textuales), alguna inédita.

Integridad emocional. Sobre cómo ser espiritual en un mundo escéptico
Authors: Molano Bustacara Alejandra , Cuéllar Saavedra José Edwin , Pérez Jiménez Miguel Ángel
Published: September 2018

El tema del presente trabajo es la espiritualidad en un mundo secularizado. Se propone que la teoría de la integridad emocional de Solomon, hace explícita una forma de espiritualidad que no la hace depender de la fe religiosa. Por eso, es una buena herramienta para comprender la espiritualidad en un mundo con distintas formas de religiosidad, ateísmo y agnosticismo. Esta espiritualidad asume una concepción cognitivista de las tres emociones tradicionalmente reconocidas como éticas y espirituales: la felicidad, la gratitud y el amor. Según dicha concepción, las emociones en general son juicios cuyo contenido es un objeto valorado de alguna forma. Estas tres emociones tienen otros estados emocionales como objetos intencionales, por eso se las llama metaemociones. Ser espiritual involucra una consideración de nuestra vida en su conjunto, valorada afectivamente desde un presente concreto. Así entendida, la espiritualidad es la clave de la construcción del sentido vital de cada persona. La espiritualidad afectiva se enmarca en una teoría de la integridad emocional. Según esta, los seres humanos somos capaces de un sinfín de emociones. En este sentido, la capacidad para procurarnos una vida afectiva íntegra es la capacidad para forjar lo que somos, para afrontar los retos del mundo, es como construimos el sentido de nuestra propia vida.
La narrativa imaginativa como vía de acceso a la solidaridad. Una propuesta educativa desde el pragmatismo y el neopragmatismo
Authors: Patiño Martha
Published: September 2018

Este artículo plantea la necesidad de reconocer las formas de narrativa presentes en los procesos educativos, y plantea la necesidad de integración de otra forma más sutil y orientada a la educación de la sensibilidad para la solidaridad, ya que se parte de la hipótesis que sostiene que los individuos se educan en dos formas particularmente poderosas de racionalidad, que derivan una insensibilización hacia los demás y hacia la naturaleza, evidenciado en egoísmo radical, en el consumismo inconsciente, en la exclusión de los demás y en la destrucción de la naturaleza. Como método de análisis, se examina el problema a la luz de la crítica al pensar objetivo-positivo, desde el pragmatismo clásico de Dewey y el neopragmatismo de Rorty, del mismo modo que se presenta la correspondiente crítica a la razón instrumental-tecnológica desde la escuela de Frankfurt. Todo lo anterior con la finalidad de ofrecer una propuesta de un léxico, una narrativa imaginativa que se oriente hacia la creación de un ethos de la empatía y la solidaridad, el cual se considera una perspectiva utópica, posible solo en la medida en que se haga visible otro ámbito de lo humano, para hacer posible el progreso moral que como humanidad constituye nuestra responsabilidad.
Gansos volando en forma de V: construcción de comunidad, eficacia colectiva y espacio defendible en un barrio de Cali, Colombia
Authors: Molina Correa Javier Alexander
Published: September 2018

La ciudad de Santiago de Cali en Colombia se ha caracterizado desde inicios de siglo, por ser una de las urbes más inseguras del mundo. Ante la incapacidad del Estado en la garantía del orden, existen iniciativas desde las comunidades en las cuales se busca mitigar la ausencia de seguridad con acciones colectivas donde se suple esta falencia institucional. Este trabajo busca explorar la experiencia del barrio Marco Fidel Suárez, una de las comunidades con menos muertes de la ciudad gracias a estrategias como el encerramiento voluntario a través de la instalación de enrejados en puntos estratégicos, la regulación de entrada y salida de residentes en anexo a actividades diseñadas e implementadas desde la Junta de Acción Comunal, en aras de la gestión de una convivencia pacífica. Se utilizan: las teorías de la “eficacia colectiva” de Robert Sampson, el “espacio defendible” de Oscar Newman y la adecuación del concepto de emulación de “espacios residenciales multifamiliares”, apoyado en herramientas metodológicas cualitativas como la entrevista y la observación pasiva, con el fin de comprender y explicar el desarrollo de las estrategias mencionadas.

Dear Sir,

From the beginning of life on this planet research and writing remained one of the most important aspect for getting more attentions and values. But, with the pas- sage of times different methods has been introduced to share the knowledge and information i.e. from hand writing to hard publication and then to online publication. Dear readers, it was a story of 2015 when the honorable Dr. Phuc Van Pham (Founder and Editor-in-Chief) came with an idea and started the journal with name Biomedical Research and Therapy is the official journal of the Laboratory of Stem Cell Research and Application (SCL) (now as Stem Cell Institute, VNUHCM University of Science, Ho Chi Minh city, Viet Nam). After launching the journal, it was thinking that the journal will not exist for long time, be- cause it was a hard journey with limited resources. However, the journal is entered in to their 5th volume in 2018. Due to the hard working, creative ideas, team working and non-stoppable efforts of Dr. Pham and his team proofed that Biomedical Research and Therapy is one the emerging journal in the field of biomedical sciences. The journal is now indexed and abstracted by world renowned databases including Web of Science, Scopus, Embase, Index Copernicus, Ebsco, and Google Scholar.

In a very short time of period the journal become more popular in the Asian countries. Researchers from different parts of the world is publishing their work in Biomedical Research and Therapy.

Developing an Internship Preparedness Program for Final Year Medical Students
Authors: Nasir Bushra , Jurd Kate , Cook Sheila , Kwan Marcella , Ostini Remo
Published: September 2018

This article was migrated. The article was marked as recommended. Introduction: Medical students undertake extensive training yet often feel they lack the practical non-medical skills required for successful transition to internship. While research provides evidence for student perceptions and experiences regarding internship, there is little information regarding how students can be 'taught' work-readiness through learning non-medical skills. Methods: By reducing cognitive load when structured using a flipped classroom method, active learning resources may provide an effective approach to prepare medical students to be work-ready interns. Using a blended instructional method, the University of Queensland's Rural Clinical School (UQRCS) integrated face-to-face and online learning, to develop an Intern Preparedness program. Discussion: The Intern Preparedness program promotes student interaction in a range of active learning tasks to improve learning and engagement in a difficult and often neglected area of professional training. The program focused on providing knowledge and skills to increase competency in non-medical skills including time management on the ward, patient-focused prioritisation of tasks, and clinical conversations with the healthcare team. Conclusion: This program has become an integral part of the student learning experiences at the UQRCS as it continues to elevate student preparedness for internship. The program has become a fundamentally important aspect of improving cognitive skills such as critical thinking and reasoning, as well as soft skills, which are all essential for successful transitions to internship. A very high uptake and completion of program activities provided further incentive for program developers to continue its improvements over time.

Electromagnetic fields related to high speed transportation systems
Authors: Kircher Roland , Klühspies Johannes , Palka Ryszard , Fritz Eckert , Eiler Kenji , Witt Michael
Published: September 2018

Issue: The potential health risks on passengers and the environment related to electromagnetic fields caused by the operation of electrically driven high speed transportation systems has become a major issue. Especially the magnetic flux density or induction can generate physiological effects in body tissues.
Aim: In this paper, we compare calculated and experimental values of electromagnetic fields in rail-wheel systems such as ICE with the Maglev-systems Transrapid and the JR Maglev-system, based on available data.
Method: To estimate the impact on passengers, the field contributions generated by the power supply system as well as by the drive and suspension systems are taken into account. For the comparison, the peak values of the electromagnetic fields have been considered.
Results: The results show, that there are no health risks from the electric fields. Regarding the magnetic induction, the calculated the peak values remain well below the limits given by national regulations. In the case of the Transrapid and the JR Maglev system, the measured peak values in the environment and inside the vehicle depend on the levitation and the guidance technology and the geometrical parameters. The JR Maglev system requires effective magnetic shielding measures which are connected with heavy materials. Since such materials may have a negative influence on the energy balance and the economics of operation, R&D efforts are focusing on the optimization of materials and the structure of shields.
Conclusion: In high speed transportation systems there are no potential risks from electrical fields. Regarding magnetic fields, the induction generated by the power supply and the drive system remain well below the frequency dependent limits. The situation is different for magnetic levitation systems, depending on the suspension and guidance technology. Especially the JR Maglev requires effective shielding measures. The shielding materials may have a negative impact on the energy balance.

Authors: Qin Feng , Lin Ying , Lu Diqiang
Published: September 2018

Aim: For exploring and testing the key technology of high-speed maglev transportation propulsion control system, this paper designs and establishes a hardware-in-the-loop (HIL) real-time simulation system of the high-speed maglev transportation five-segment propulsion system.
Materials and methods of the studies: According to the route conditions and propulsion segment division of Shanghai maglev demonstration and operation line, the real-time simulation platform based on dSPACE multiprocessor systems is implemented. The simulation system can achieve the functional simulation of all the high-power related equipment in the 5-segment area, including 8 sets of high-power converter units, 2 sets of medium-power converter units, 2 sets of low-power converter units, five-segment trackside switch stations and long-stator linear synchronous motors. The mathematical models of linear motors and converters are built in MATLAB/Simulink and System Generator, after compiling, they can be downloaded and executed in Field Programmable Logic Array (FPGA). All the interfaces connecting the simulation system to the propulsion control system physical equipment use real physical components as in the field, such as analog I/O, digital I/O, optical signals and Profibus.
Results: By using CPU+FPGA hardware configuration, the simulation steps are greatly shortened and the response speed and accuracy of real-time simulation system are improved. The simulation system can simulate multiple operating modes such as multi-segment, multi-vehicle, double-track, double-feeding, step-by-step stator section changeover, and so on. The simulation results show that the maximum speed of the simulation system can reach 500 km/h.
Conclusion: This HIL system can provide detailed real-time on-line test and verification of high speed maglev propulsion control system.

Authors: Zhou Danfeng , Yu Peichang , Li Jie , Cui Peng , Song Mengxiao
Published: September 2018

This paper is a study of the electromagnet-track coupled high frequency resonance that frequently occurs in the urban maglev systems, it includes the following points:
Aim: The purpose of this study is to investigate the principle underlying the high frequency resonance occurs between the maglev train and the track, and to develop an appropriate vibration control algorithm which can be applied in the levitation controller, such that the resonance can be eliminated when the maglev train travels along the track.
Materials and methods of the studies: In this paper, the model of the electromagnet-track coupled system is firstly established, in which some special cases, which correspond to the situations when the screws that fasten the F-rail to the sleepers are fatigue, or the stiffness of the rubber plates beneath the sleepers weaken for temperature reasons, are studied; and the reason that leads to the coupled resonance are explained as well. Secondly, an adaptive vibration control algorithm, which consists of a vibration observer and a tunable adaptive filter, is designed to suppress the high frequency electromagnet-track coupled resonance.
Results: Using this algorithm, when the train arrives at the spots where the coupled resonance may occur, the vibration observer will detect the occurring of the vibration and estimates its frequency, and then activate the adaptive filter and tune it to absorb the vibration.
Conclusion: The test indicates that this algorithm is capable of tuning itself to handle the unpredictable coupled resonance that occurs along the track, and it is simple and can be easily integrated into the levitation control code in a digital levitation control system.

Oil Spill Detection Using Otical Sensors: A Multi-Temporal Approach
Authors: Roberto LUCIANI , Giovanni LANEVE
Published: September 2018

Oil pollution is one of the most destructive consequences due to human activities in the marine environment. Oil wastes come from many sources and take decades to be disposed of. Satellite based remote sensing systems can be implemented into a surveillance and monitoring network. In this study, a multi-temporal approach to the oil spill detection problem is investigated. Change Detection (CD) analysis was applied to MODIS/Terra and Aqua and OLI/Landsat 8 images of several reported oil spill events, characterized by different geographic location, sea conditions, source and extension of the spill. Toward the development of an automatic detection algorithm, a Change Vector Analysis (CVA) technique was implemented to carry out the comparison between the current image of the area of interest and a dataset of reference image, statistically analyzed to reduce the sea spectral variability between different dates. The proposed approach highlights the optical sensors’ capabilities in detecting oil spills at sea. The effectiveness of different sensors’ resolution towards the detection of spills of different size, and the relevance of the sensors’ revisiting time to track and monitor the evolution of the event is also investigated.

Published: September 2018

Background: India has the third largest number of people living with HIV/AIDS. India is estimated to have 75,900 new adults with HIV infections. The prevalence of HIV infection was 0.7% in India, 0.26% in Tamil Nadu in the year 2017. HIV related stigma remains an important barrier in effectively fighting against HIV/AIDS. The objectives of the study were to assess knowledge regarding HIV/AIDS among medical students and to assess attitude towards HIV/AIDS among medical students.Methods: A cross-sectional study conducted among 1st year undergraduates of Sree Balaji Medical College. Sample size was calculated using 4pq/L2, computed to a total of 240. Data collection was done using pretested structured questionnaire, containing 7 questions and 5 questions regarding knowledge and attitude towards HIV/AIDS respectively. Data was entered in MS excel and analysed using SPSS software version 22.Results: Among the participtants, 46% were male and 54% were female. 91% of study participants had adequate knowledge (94% knew that HIV was preventable, 89% knew about the mode of spread, 90% knew about transmission prevention) and 84% of the study participants had good attitude.Conclusions: This knowledge and attitude study was to assess the current level of knowledge among first year MBBS students about AIDS at the point of entry to medical course. Few misconceptions were found to exist regarding mode of transmission and prevention. Awareness programmes should be initiated among the MBBS students in the first year itself, so that these lacunae can be rectified.

Published: September 2018

Background: Menstrual abnormalities are a major gynaecological problem faced by adolescent girls leading to morbidity that may have an adverse effect on their school attendance. The objective of the study was to determine prevalence of menstrual disorders in girls aged 10-19 years and to study their treatment-seeking behaviour.Methods: We conducted a cross-sectional study on 592 girls in the age group of 10 to 19 years attending schools in Pune city during January 2016 to December 2016. Permission was sought from school authorities. Girls 10-17 years were included after obtaining parental consent. For 18 and 19 year olds, informed consent was taken from the girls themselves. Demographic information, height, weight and characteristics of menstrual period were noted.Results: Majority girls (36%) were in age group 12.1-14 years. Most prevalent menstrual disorder was painful menses reported by 70% of girls, followed by heavy menstrual bleeding (46%) and cycle irregularity (22%). All menstrual disorders were most commonly prevalent in the age group of 14.1 to 16 years. Proportion of girls visiting a doctor and taking medications for painful menses was 26.7% and 16.5% respectively, for heavy menstrual bleeding was 25.7% and 16.5% respectively and for cycle irregularity was 33% and 16.5% respectively. No association was found between mother’s education and treatment seeking behaviour for menstrual disorders.Conclusions: In spite of high prevalence of menstrual disorders, only a minority of the adolescents seek expert advice. This underscores the need for creating awareness among girls, mothers and teachers and developing a screening tool to identify girls who could benefit by further investigation and follow-up.

Objetivo: Trata-se do relato da trajetória de Sofia que teve suas filhas gêmeas adotadas compulsoriamente. Analisa-se seu percurso nas redes do Sistema Único de Assistência Social em Belo Horizonte, MG, discutindo como o julgamento e os estereótipos criados nesta trajetória definiram a adoção. Métodos: Pesquisa qualitativa, do tipo interferência, delineado como estudo de caso, definido a partir da experiência e percurso de uma usuária-guia. Resultados: O percurso de Sofia nos múltiplos pontos da rede foi atravessado por estabelecimento de vínculos, demandas, ofertas e desejos. O fato de ser mulher, negra, pobre, usuária de drogas, ter trajetória de rua, vínculos fragilizados ou rompidos, parece ter contribuído na construção de falas relativas às incapacidades e estereótipos acerca de Sofia.Conclusão: A adoção compulsória foi resultado de um complexo processo que envolveu julgamentos sobre Sofia, sem considerar seus desejos, demandas e necessidades. As redes existentes foram limitadas para captar e apreender toda a amplitude e pluralidade das demandas apresentadas e para operar na produção do cuidado. Assim, os direitos de vir a ser de Sofia foram sequestrados com a adoção de suas filhas.

Küreselleşen
dünyamızda yaşanan finansal krizler ile birlikte bankacılık alanında denetim ve
gözetimin zorunlu bir hal aldığı görülmektedir. Bu amaç doğrultusunda 1974
yılında yaşanan Dünya Petrol Krizi sonrası 1988 yılında Basel Komitesi
tarafından Sermaye Yeterlilik Uzlaşısı geliştirilmiştir. Türkiye'de 1989
yılından itibaren Basel I, 2006 yılından itibaren Basel II standartlarının
kapsamlı versiyonu uygulanmaktadır. Çalışmanın amacı, BIST'te işlem gören
bankaların sermaye yeterliliklerine göre karşılaştırılmasıdır. Çalışma,
2012-2017 yılları arasında BIST'te işlem gören 13 bankayı kapsamaktadır. Bu
doğrultuda bankaların sermaye yeterlilik oranları kullanılarak WASPAS yöntemine
göre değerlendirilmiştir. Sonuç olarak sermaye yeterliliği açısından Albaraka,
Kalkınma ve TSKB bankaları en iyi; QNB Finansbank ve Denizbank’ın ise genelde
düşük düzeyde oldukları görülmüştür. Yine, 2013 yılında sermaye yeterlilik
düzeyleri ile hisse senedi getirileri arasında anlamlı bir ilişki tespit
edilmiştir.

Araştırmanın
amacı, katılımcı çalışma ikliminin kurumsal itibar algısı üzerindeki etkisinde
kişi-iş ve kişi-kurum uyumunun aracılık rolünün olup olmadığı ortaya
çıkarmaktır. Katılımcı çalışma iklimi de katılımcılığın bu özelliğinin çalışma
ikliminde ne derecede olduğunu ortaya çıkarmaktır. Kişi-Kurum uyumu Schneider
(1987)’in Çekim-Seçim-Yıpranma (Attraction-Selection-Attrition) modeline
dayanmaktadır. Bu model kişilerin rasgele durumlara atanmadığını, ancak daha
çok cazip durumları araştırdıklarını savunmaktadır. Kişi-iş uyumu da bu değer
eşleşmesinin kişi ve yaptığı iş ve görevlerde ne derecede olduğunun tespitine
odaklanmaktadır. Kurumsal itibar kavramının temelinde de kişinin itibarında
olduğu gibi “güven” ve “inanç” kavramları bulunmaktadır. Bahsi geçen ilişki ve
etkileri ortaya çıkarmak için bu çerçevede İstanbul’da istihdam edilmiş olan
283 çalışan üzerine anket çalışması yapılmıştır. Sonuçta kişi-kurum uyumunun
katılımcı iklim ile kurumsal itibar ilişkisinde aracılık rolü üzerine bir
araştırma yapılmış olup aracılık rolü ortaya konulmuştur.
The Tom (The Turkey)

Nikolay GumilevThe Tom (The Turkey)Translated from Russian by Anne Becker and Leonid Margolis) From the dawn of my unfaithful memories,I recollect a dappled meadowWhere reigned a haughty TomWhom I adored. Independence and rage were in him;His beak was as scarlet as flame;And because I was four years old,He roundly despised me. Neither chocolate nor caramels,Nor pineapple soda,Could console meFor the knowledge of my shame. Today a great anguish returns,With the humiliation and grief of my early years,When you, my adored, cruel,Proudly deny me. But everything passes in this fluid life,Love will pass, sorrow will pass,And I will recall you with a smileAs I recall the turkey.
DIFERENTES DENSIDADES EM CULTIVO DO CAMARÃO BRANCO USANDO BIOFLOCOS E ÁGUA DE SUBSOLO EM CLIMA SUBTROPICAL

Nos últimos anos, há uma forte tendência para produção de camarões marinhos em sistema de bioflocos. Este sistema favorece o aumento das densidades de estocagem utilizando menores áreas. Além disso, o uso de água de subsolo também pode ser uma alternativa para empreendimentos afastados do litoral. Em áreas subtropicais a temperatura é um importante parí­¢metro a ser considerado, pois pode reduzir o perí­­odo de cultivo em viveiros. Este estudo teve como objetivo avaliar a viabilidade da produção de Litopenaeus vannamei, comparando duas densidades de estocagem (100 e 150 camarões m-2), utilizando bioflocos e água do subsolo. O experimento foi realizado entre janeiro a abril de 2011 (105 dias) na Estação Marinha de Aquacultura (EMA/FURG), localizada na cidade do Rio Grande, RS, Brasil. Os camarões foram estocados em viveiros de 600 mÂ² com pós-larvas de 0,08 Â± 0,03 g (PL 40), sendo utilizadas três réplicas para cada tratamento. Os parí­¢metros de qualidade da água e composição iônica estavam dentro dos limites aceitáveis para L. vannamei. No desempenho zootécnico, a conversão alimentar em ambos os tratamentos pode ser atribuí­­da pelo consumo de flocos microbianos pelos camarões. As densidades apresentaram diferença significativa na produtividade: 9.748 e 13.860 kg ha- 1 para 100 e 150 camarões m-2, respectivamente. Embora a temperatura da água tenha diminuí­­do nas duas últimas semanas (19,4 Â°C), a sobrevivência foi 97 % (100 camarões m-2) e 88 % (150 camarões m-2). No sul do Brasil, as densidades testadas 100 e 150 camarões m-2 foram adequadas apresentando valores eficientes de crescimento, sobrevivência e conversão alimentar dos camarões. No entanto, a densidade de 150 camarões m-2 foi mais rentável devido í­Â  alta produtividade. Neste estudo, a relação iônica foi mais baixa do que os valores da água do mar, mas isto não afetou o desempenho zootécnico dos animais. Em relação í­Â  localização, deve-se levar em consideração que as condições climáticas nesta área possibilitam cultivo de camarão em viveiros durante os meses mais quentes.

O estudo de fontes de proteí­­nas alternativas é muito importante para reduzir o custo de dietas aquí­­colas. Neste estudo foi avaliada a utilização de resí­­duos do processamento de jundiá (Rhamdia quelen) na dieta de juvenis desta espécie. Deste modo, foi utilizado sistema de recirculação com 16 tanques de polipropileno (280 L), cada um com 50 peixes (peso inicial = 5,5 Â± 0,09 g). Foram testadas quatro dietas (37% de proteí­­na bruta e 3.200 kcal-1 kg de energia digestí­­vel): dieta controle, composta por farinha de carne e ossos suí­­na, substituí­­da por farinha de peixe, composta por peixe inteiro (jundiá), farinha de carcaças de jundiá com ví­­sceras e dieta com farinha de carcaças de jundiá sem ví­­sceras. Foi avaliado, o peso final, fator de condição, taxa de crescimento especí­­fico, taxa de conversão alimentar, ganho de peso diário e taxa de retenção de proteí­­na. Observou-se maior peso final (50,5 g), taxa de crescimento especí­­fico (3,9% dia-1), conversão alimentar (1,3:1), deposição de proteí­­na corporal (6,3 g) para os peixes alimentados com as dietas compostas por farinha de carcaça de jundiás com ví­­sceras. A incorporação de farinha de resí­­duos do processamento de jundiás na dieta é viável para o crescimento dos peixes.
