IPS’ Technology and Industrial Management graduate course: a curriculum followup analysis

The Technology and Industrial Management (T&IM) course of the Polytechnic Institute of Setúbal (IPS), Portugal, is a four year graduate course organized in trimesters with three course units per trimester [quarter]. In the last two trimesters [quarters] internships or real context projects prepare students for a smoother integration in the professional activity. From its beginning, in 2007, T&IM was designed for adults who develop a full-time professional activity in industrial companies, and needed to supplement their skills with those typical of managers and engineers. The b-learning methodology was adopted since it enabled the targeted students to better reconcile their academic, professional and family responsibilities. In 2010-2011 the first T&IM students concluded their graduate studies and, within IPS’ Integrated Management System, it was decided to monitor the suitability of the T&IM course curriculum. The following activities were undertaken: (a) data analysis, (b) satisfaction survey to current and graduate students, and (c ) focus groups with graduate students that had finished the course in 2010-2011. The data showed lower dropout numbers than those of IPS’ engineering courses. The survey showed good levels of satisfaction. Student satisfaction is high for curriculum related topics such as: (1) the course’s ability to develop transversal skills and (2) the course teaching methodology. Comparing graduate and current students survey results, the former group declares a higher overall satisfaction with the course. These results are consistent with those gathered from the focus group. During the focus group graduate students added that the skills acquired were comprehensive and appropriate to their understanding of how organizations actually operate. From the gathered results it is concluded that there is a good level of curriculum adequacy and student satisfaction, although there are “problem areas” and topics requiring further research.Com o apoio RAADRI

As pequenas memórias de Saramago

As pequenas memórias é uma obra de agradável e fácil leitura, apesar das cenas e mensagens intensas nela presentes. Neste livro, José Saramago recria, de forma magistral, as impressionantes paisagens e aventuras da sua infância e juventude, vividas entre o ambiente rural do Ribatejo e o urbano de Lisboa. Nesta pequena autobiografia, Saramago constrói, a partir de reminiscências sobre a sua vida privada, um conjunto de sólidas reflexões poéticas, cheias de considerações históricas críticas sobre as mudanças vividas com a entrada de Portugal para a União Europeia. Este livro permite compreender o impacto das experiências juvenis sobre a sua alma de escritor. Adicionalmente, ao longo de toda a narrativa, são dadas a conhecer não só as origens do seu nome, como também de muitos títulos e enredos de romances que, posteriormente, viriam a ser escritos por ele.info:eu-repo/semantics/publishedVersio

Extending Eventually Consistent Cloud Databases for Enforcing Numeric Invariants

Geo-replicated databases often operate under the principle of eventual consistency to offer high-availability with low latency on a simple key/value store abstraction. Recently, some have adopted commutative data types to provide seamless reconciliation for special purpose data types, such as counters. Despite this, the inability to enforce numeric invariants across all replicas still remains a key shortcoming of relying on the limited guarantees of eventual consistency storage. We present a new replicated data type, called bounded counter, which adds support for numeric invariants to eventually consistent geo-replicated databases. We describe how this can be implemented on top of existing cloud stores without modifying them, using Riak as an example. Our approach adapts ideas from escrow transactions to devise a solution that is decentralized, fault-tolerant and fast. Our evaluation shows much lower latency and better scalability than the traditional approach of using strong consistency to enforce numeric invariants, thus alleviating the tension between consistency and availability

The compression chord capacity model for the shear design and assessment of reinforced and prestressed concrete beams

This is the accepted version of the following article: [Cladera, A., Marí, A., Bairán, J. M., Ribas, C., Oller, E. and Duarte, N. (2016), The compression chord capacity model for the shear design and assessment of reinforced and prestressed concrete beams. Structural Concrete, 17: 1017–1032. doi:10.1002/suco.201500214], which has been published in final form at http://onlinelibrary.wiley.com/doi/10.1002/suco.201500214/fullA simplified mechanical model is presented for the shear strength prediction of reinforced and prestressed concrete members with and without transverse reinforcement, with I, T or rectangular cross-section. The model, derived with further simplifications from a previous one developed by the authors, incorporates the contributions of the concrete compression chord, the cracked web, the dowel action and the shear reinforcement in a compact formulation. The mechanical character of the model provides valuable information about the physics of the problem and incorporates the most relevant parameters governing the shear strength of structural concrete members. The predictions of the model fit very well the experimental results collected in the ACI-DAfStb databases of shear tests on slender reinforced and prestressed concrete beams with and without stirrups. Due to this fact and the simplicity of the derived equations it may become a very useful tool for structural design and assessment in engineering practice.Peer ReviewedPostprint (author's final draft

Die rußländische Sicherheitspolitik um die Jahrtausendwende

13 pages, 3 figures, 6 tablesThe metabolic carbon requirements and excretion rates of three major zooplankton groups in the Southern Ocean were studied in the vicinity of the Antarctic Peninsula in February 2009. The research was conducted in the framework of the ATOS project (POL2006-00550/CTM), as part of the Spanish contribution to the International Polar Year. Our objective was to ascertain the possible consequences of changes on size spectrum and community structure of the Southern Ocean zooplankton for the cycling of biogenic carbon and the stoichiometry of dissolved inorganic nutrients. The carbon respiratory demands and NH4-N and PO4-P excretion rates of < 5 mm size copepods, krill (represented by furcilia spp. and adult Euphausia superba) and salps (blastozoids of Salpa thompsoni) were estimated by incubation experiments. The respiration rates and N:P metabolic quotients of salps were more than twice those of krill (furcilia spp. and adults) and copepods. The possible community shift from krill to salps in the Southern Ocean would therefore encompass not only the substitution of a pivotal zooplankton group (krill) by one with an apparently indifferent role in Antarctic food webs and with higher specific metabolic carbon demands (salps), but the changes in the proportion of zooplankton-recycled N and P would modify the N:P stoichiometry of the dissolved nutrient pool, thus inducing changes in the functional and structural properties of phytoplankton that would translate to the whole Southern Ocean ecosystemThis work was supported by the Spanish funded projects ATOS (POL 2006-0550/CTM) to Carlos M.

Tecnologia da irrigação na África do Sul e no Quênia

This paper reviews various irrigation technologies in both South Africa and Kenya that enable improvements in their socio-economic conditions. The two countries are located in semi-arid areas that experience extreme fluctuations in the availability of rain water for plant growth. Population growth exceeds the ability to produce food in numerous countries around the world and the two countries are not an exception. This experiment examined the constraints that farmers face and the role of government and nongovernmental organization in the uptake of modern technologies for irrigation. Detailed mechanisms and options to secure sustainable irrigation which are economically viable are considered. Despite the higher production of cereals and grains, fruits, and flowers also thrive in the two countries. Total irrigated area, crops grown and irrigation systems used in the two countries are discussed.Este trabalho aborda as tecnologias de irrigação utilizadas na África do Sul e no Quênia que possibilitam melhorias nas suas condições sócio-econômicas. Localizados em regiões semiáridas, esses países estão susceptíveis à extrema flutuação na disponibilidade de precipitação pluviométrica para o desenvolvimento das plantas. O crescimento populacional, como em muitos países, excede à capacidade de produção alimentar. Neste trabalho foram levantados as dificuldades que enfrentam os produtores rurais e o papel do governo e das instituições de pesquisa não governamentais na captação de tecnologias modernas para a irrigação. Detalhados mecanismos de execução e opções para garantir a irrigação sustentável e economicamente viável foram considerados. Apesar da maior produção de cereais e grãos, a fruticultura e a floricultura também prosperam nesses países. A área irrigada total, as culturas beneficiadas e os sistemas de irrigação usados nesses países também foram discutidos

Testicular biometric characteristics in Santa Inês sheep submitted to protein supplementation

Para avaliar as características biométricas testiculares de carneiros da raça Santa Inês, 24 cordeiros machos, inteiros, com peso médio inicial de 24,5 kg ± 2,88, aos quatro meses de idade, foram distribuídos em quatro tratamentos: APv (animais vermifugados + concentrado com alta proteína), APn (animais não-vermifugados + concentrado com alta proteína), BPv (animais vermifugados + concentrado com baixa proteína), BPn (animais não vermifugados + concentrado com baixa proteína) durante 8 meses e meio. Antes do abate, realizaram-se as medições testiculares in situ: perímetro escrotal (PE), comprimento (COMP), largura testicular (LARG) e a forma dos testículos, bem como o volume testicular (cilindro e prolato esferóide). Após o abate, determinaram- se o volume testicular real (VOLR), o comprimento (COMPV) e a largura testicular (LARGV). Observou-se que os testículos dos animais eram simétricos e que o uso do paquímetro é uma forma altamente confiável para se realizar as medições testiculares in situ. O formato dos testículos afetou diretamente seu volume. O valor médio das equações do prolato esferóide e cilíndrica é a forma mais acurada para se estimar o volume testicular real em ovinos Santa Inês. O alto teor de proteína da dieta e o tratamento antiparasitário possibilitaram uma melhoria do peso corporal dos ovinos, sendo o principal fator de variação para as características biométricas testiculares. _____________________________________________________________________________________ ABSTRACTBiometric testicular traits were evaluated on 24 entire male Santa Inês lambs, with mean initial weight of 24.5 kg ± 2.88. These were distributed in four treatments (n=6): HPv (animals drenched + high protein concentrate), HPn: (animals not drenched + high protein concentrate), LPv: (animals drenched + low protein concentrate), LPn: (animals not drenched + low protein concentrate) for eight and a half months. Before slaughter testicular measurements were taken in situ. Scrotal perimeter (SC) was measured using tape as well as length (LENG) and width (WID) using calipers. Testicular shape and volume (using prolate and cylinder equation) were calculated. After slaughter the measurements were taken in vitro. Real testicle volume (VOLR) was measured using water displacement. Length (LENGV) and width (WIDV) were measured with calipers after skin removal. The testicles were symmetrical and calipers were an accurate means of in situ measurement of the testicle size. The form of the testicles affected the volume. The average of the prolate sphere and cylinder equations gave the best estimate for real testicle volume. High protein levels in the diet accompanied by antihelminth treatment led to higher body weight in the sheep, this being the main factor for variation in testicle biometric traits
