Improving the 14c dating of marine shells from the Canary Islands for constructing more reliable and accurate chronologies
Radiocarbon dating of closely associated marine mollusk shells and terrestrial material (charred wood or bone) collected from archaeological contexts on Tenerife and Fuerteventura islands allowed us to quantify the marine C-14 reservoir effect (Delta R) around the Canary Archipelago. Coastal Fuerteventura has a positive weighted mean Delta R value of +185 +/- 30 C-14 yr, while for Tenerife a range of negative and positive values was obtained, resulting in a Delta R weighted mean value of 0 +/- 35 C-14 yr. These values are in accordance with the hydrodynamic system present off the Canary Islands characterized by a coastal upwelling regime that affects the eastern islands (Fuerteventura and Lanzarote) but not the other islands of the archipelago, namely Tenerife. Because of this oceanographic pattern, we recommend the extrapolation of these results to the remaining islands of the archipelago, i.e. the first value must be used for the eastern islands, while for the central and western islands the acceptable Delta R value is 0 +/- 35 C-14 yr
Exploring sizable triple Higgs couplings in the 2HDM
An important task at future colliders is the measurement of the triple Higgs
coupling. Depending on its size relative to the Standard Model (SM) value,
certain collider options result in a higher experimental accuracy. Within the
framework of Two Higgs Doublet Models (2HDM) type I and II we investigate the
allowed ranges for all triple Higgs couplings involving at least one light,
SM-like Higgs boson. We take into account theoretical constraints (unitarity,
stability), experimental constraints from direct Higgs-boson searches,
measurements of the SM-like Higgs-boson properties, flavor observables and
electroweak precision data. We find that the SM-type triple Higgs coupling
w.r.t. its SM value, , can range between and . Depending on which value is realized, the HL-LHC can
compete with, or is clearly inferior to the ILC. We find the coupling
between and . Triple Higgs couplings
involving two heavy Higgs bosons, , and
can reach values up to , roughly independent
of the 2HDM type. This can lead to potentially strongly enhanced production of
two Higgs-bosons at the HL-LHC or high-energy colliders.Comment: 44 pages, 16 figure
PERANCANGAN KOMIK KREASI CERITA GATOTKACA “PRINCE OF PRINGGADANI”
So many culture in Indonesia who began forgotten by the next generation
of Indonesia such as puppet show, excess of puppet show that is reflection of the
temper of man. Gatokaca is one of the traditional arts of puppet character, knight
of Pringgadani, son of Werkudara and Dewi Arimbi. That strong kninght has the
nickname “iron wire and bone muscle”. Many are not knowing the story of the
puppet character, as the young generation shall be obliged to love and preserving
puppet, because it has been being inherited from ancestors the Indonesia nation.
Now this comic has been part of pop culture and constituting literary work
visual very popular various parties from years ago until now, because comic
books more easily understood by the reader. Those things that drive choose the
title of this final project design, aiming to provide an alternaive media read to the
next generation about the puppet character and story. The story of Gatotkaca
packaged adjust to teenagers that readers are more interested with the comic as
well as more love traditional culture of puppet.
Design comic creation story Gatotkaca “Prince of Pringgadani” form of
comic book undersized A5 potrait and full color. Using concept “everyone can be
a hero” showing or giving an image of a puppet the imagination of the audience
who apprehends all that is in the story puppet in accordance with versions of each
individual. The message to be delivered is no less exciting puppet stories
compared with superhero stories from overseas, increasing the sense of love for
the culture and preserving the culture of Indonesia.

Seizing the present, consolidating the future: educational technology in health
A tecnologia educativa possibilita a utilização de metodologias operativas dinâmicas, com a
principal finalidade de fomentar a eficácia dos processos de formação, oferecendo uma gama de
conhecimentos, coerentes e sólidos, sobre a forma de organizar os processos de ensinoaprendizagem,
planear e elaborar ambientes e processos educativos, com o intuito de atingir os
objectivos pedagógicos previamente definidos, aspectos que se podem aplicar na educação para
a saúde, nomeadamente na saúde escolar. As políticas internacionais de promoção de saúde e a
configuração dos próprios sistemas de saúde, tornam importante a análise das concepções
subjacentes à tecnologia educativa, convergindo para a reflexão dos seus impactos na
actualidade, enquanto peças centrais de dimensionamento das estratégias desenvolvidas no
âmbito da saúde. Ampliando as possibilidades do acesso à informação, a sua utilização permite
desenvolver estratégias que facultem não só o desenvolvimento de conhecimentos e
competências, como a actualização e a capacitação dos indivíduos, englobando-o num processo
de aprendizagem ao longo da vida, afirmando-se desta forma como uma importante linha de
investigação a considera
Social capital and health: a structural interaction area
Nos últimos anos têm-se vindo, progressivamente, a constatar que o capital social se encontra, inequivocamente, relacionado com a edificação de estruturas comunitárias que promovam estratégias de empoderamento e desenvolvimento sustentado, fomentando melhorias na qualidade de vida dos indivíduos, influenciando o surgimento de benefícios globais ao nível da saúde coletiva, pelo contributo facultado na identificação e satisfação das necessidades de diferentes populações-alvo. Alguns estudos empíricos apontam a existência de uma relação entre as diferentes formas de capital social e os ganhos em saúde, individuais e coletivos, ao nível da saúde física, da saúde mental e dos comportamentos e atitudes relacionados com estilos de vida saudável, facto que leva a poder encarar a conexão estabelecida entre capital social e saúde como uma eventual estratégia de dimensão global, sustentada e sustentável de promoção da saúde e de desenvolvimento sociocomunitário. Neste domínio, a mobilização das diferentes estruturas comunitárias, alicerçada na concertação da participação coletiva e no estabelecimento de relações em que impera a confiança mútua, representa uma verdadeira representação de vitalidade, que possibilita concetualizar a saúde como um fenómeno que associa a qualidade de vida dos indivíduos, grupos e comunidades às principais dimensões que emergem do conceito de capital social
After the experience, what does remain?
As novas exigências com as quais se confronta o ensino superior assentam numa formação onde é
cada vez mais reconhecido o interesse de envolver na gestão do sistema de ensino/formação, uma
maior diversidade de actores sociais, ensaiando modalidades de articulação consubstanciadas em
redes de cooperação, onde o estudante é participante activo. Importa por isso analisar, a forma como
são articulados os saberes oriundos da escola com as experiências clínicas vivenciadas em contexto
real de trabalho ao longo do Curso de Licenciatura em Enfermagem, para caracterizar os impactos
que estas experiências têm na estruturação da percepção dos estudantes, acerca das funções do
enfermeiro e das repercussões destas no seu processo de desenvolvimento
Evolutionary rule-based system for IPO underpricing prediction
Genetic And Evolutionary Computation Conference. Washington DC, USA, 25-29 June 2005Academic literature has documented for a long time the existence of important price gains in the first trading day of initial public offerings (IPOs).Most of the empirical analysis that has been carried out to date to explain underpricing through the offering structure is based on multiple linear regression. The alternative that we suggest is a rule-based system defined by a genetic algorithm using a Michigan approach. The system offers significant advantages in two areas, 1) a higher predictive performance, and 2) robustness to outlier patterns. The importance of the latter should be emphasized since the non-trivial task of selecting the patterns to be excluded from the training sample severely affects the results.We compare the predictions provided by the algorithm to those obtained from linear models frequently used in the IPO literature. The predictions are based on seven classic variables. The results suggest that there is a clear correlation between the selected variables and the initial return, therefore making possible to predict, to a certain extent, the closing price.This article has been financed by the Spanish founded research MCyT project TRACER, Ref: TIC2002-04498-C05-04M
ALTERNATIF PROTEASE PADA ENZIM RENNET DALAM PEMBUATAN KEJU
Rennet merupakan kombinasi dari enzim protease seperti kimosin dan pepsin yang didapatkan dari abomasum anak sapi. Enzim kimosin sendiri merupakan enzim yang memiliki pengaruh dominan terhadap peristiwa koagulasi pada susu menjadi curd dan whey dalam pembuatan keju. Beberapa alternatif dari enzim rennet dapat berasal dari bahan pangan non-hewani, seperti enzim papain (dari ekstrak getah buah pepaya), enzim zingibain (ekstrak rimpang jahe), enzim cucumisin (ekstrak bagian sarkokarp melon), dan bromelin (ekstrak batang dan buah nanas). Parameter yang diamati dari beberapa jurnal berkaitan dengan sumber, pH dan suhu optimum, rasio antara milk clotting activity (MCA) dengan proteolytic activity (PA), persentase cheese yield serta hardness keju. Hasil yang didapatkan dari akumulasi beberapa jurnal dan ditabulasikan untuk mengetahui perbedaan karakteristik dan kualitas dari masing-masing enzim. Keju yang dihasilkan oleh enzim papain memiliki karakteristik aroma manis, floral, dan fruity akibat pembentukan asam asetat dan aldehid, sedangkan penambahan enzim zingibain menghasilkan keju dengan senyawa aromatik yang cukup kuat. Enzim cucumisin yang ditambahkan pada proses pembuatan keju menghasilkan karakteristik hardness yang rendah dengan nilai minimum sebesar 1,97 N, sedangkan penambahan enzim papain mampu menghasilkan hardness yang paling tinggi pada nilai maksimum 13,79 N. Adapun penambahan enzim bromelain mampu menghasilkan keju dengan karakteristik pahit yang rendah pada keju yang dihasilkan
