Abstract: sugar snap peas (pisum sativum l.) are edible-podded peas that, unlike snow (chinese) peas, have thick pod walls. they are the result of the combination of at least six recessive genes controlling pod and grain traits, and two others are being incorporated in modern cultivars. sugar snap peas may be consumed fresh or frozen, and are highly appreciated in the united states and other countries. six genotypes from the usa were evaluated at two locations in la araucania region in southern chile in 2004 and 2005. most sugar snap varieties showed yields similar to a freezable cultivar used as a check. yield differences among sugar snap varieties were small and inconsistent; however, cv. sweet ann performed relatively well and showed the best freezing quality. over 15 t ha-1 of pods were obtained under favorable conditions, suggesting that yields around 10 t ha-1 are quite achievable commercially. all varieties presented, at variable levels, suture on both dorsal and ventral sides of the pods. a mild frost (-2 °c), harmless to the plant, may also deteriorate the appearance of the pods. sugar snap peas are a delicate produce and, if well managed, can be a sound option to diversify chilean horticultural offer.
Electroweak physics at LHCb
Simone Bifani
Physics , 2014,
Abstract: Measurements of electroweak boson production provide an important test of the Standard Model at the LHC energies and allow the partonic content of the proton to be constrained. $W$ and $Z$ bosons are reconstructed in several leptonic final states using data samples corresponding to an integrated luminosity of up to about 1 $fb^{-1}$. Inclusive and associated production cross-sections are reported.

We studied changes in growth factor levels released from human mesenchymal stem cells in the vitreous cavity as well as changes in growth factor levels in host retinal neurons following intravitreal injection. Methods: Twenty-two Lewis rats were treated with an intravitreal human mesenchymal stem cell microinjection. Determination of neurotrophic factors released by human mesenchymal stem cells in the vitreous was carried out using real-time polymerase chain reaction. Results: Detectable levels of neurotrophic factors were identified postoperatively in the vitreous of all rats. Conclusion: Increased intravitreal and retinal concentrations of neuroprotective growth factors in rats confirm the neuroprotective activity of human mesenchymal stem cells in diabetic retinopathy.
Facts and Perceptions Regarding Software Measurement in Education and in Practice: Preliminary Results  [PDF]
Mónica Villavicencio, Alain Abran
Journal of Software Engineering and Applications (JSEA) , 2011, DOI: 10.4236/jsea.2011.44025
Abstract: How is software measurement addressed in undergraduate and graduate programs in universities? Do organizations consider that the graduating students they hire have an adequate knowledge of software measurement? To answer these and related questions, a survey was administered to participants who attended the IWSM-MENSURA 2010 conference in Stuttgart, Germany. Forty-seven of the 69 conference participants (including software development practitioners, software measurement consultants, university professors, and graduate students) took part in the survey. The results indicate that software measurement topics are: 1) covered mostly at the graduate level and not at the undergraduate level, and 2) not mandatory. Graduate students and professors consider that, of the measurement topics covered in university curricula, specific topics, such as measures for the requirements phase, and measurement techniques and tools, receive more attention in the academic context. A common observation of the practitioners who participated in the survey was that students hired as new employees bring limited software measurement-related knowledge to their organizations. Discussion of the findings and directions for future research are presented.
Relevance of Epistemological Pluralism for Resource Management Policies  [PDF]
Mónica Gómez Salazar
Open Journal of Philosophy (OJPP) , 2015, DOI: 10.4236/ojpp.2015.56039
Abstract: The common believe of a single successful form of knowing the reality is misleading. A brief analysis of many human activities reveals a pluralistic perspective of several coexisting conceptual schemes that underlie the form in which women and men know and constitute the world in which we live. Here, I will discuss the necessity of taking seriously this pluralistic perspective when developing conceptual frameworks of human activities. As an example of great interest and importance, I will consider the case of resource management that has to contemplate the conservation and the response of ecosystems to human activities that may lead to irreversible damage. Ecosystems’ activity occurs over a wide range of space and time scales and, hence, policies and proposals of solutions to ecological problems should avoid narrow and monochromatic approaches. Specifically, the Pemon perspective of fire is a good example to show that for more robust and flexible resource management we need the knowledge and experience of different cultural and disciplinary groups.
A Matching Model on the Use of Immigrant Social Networks and Referral Hiring  [PDF]
Mónica García-Pérez
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.24070
Abstract: Using a simple search model, with urn-ball derived matching function, this paper investigates the effect of firm owner’s and coworkers’ nativity on hiring patterns and wages. In the model, social networks reduce search frictions and wages are derived endogenously as a function of the efficiency of the social ties of current employees. As a result, individuals with more efficient connections tend to receive higher wages and lower unemployment rate. However, because this efficiency depends on matching with same-type owners and coworkers, there is also a differential effect among workers’ wages in the same firm. This analysis highlights the potential importance of social connections and social capital for understanding employment opportunities and wage differentials between these groups.
Assessing spatial genetic structure from molecular marker data via principal component analyses: A case study in a Prosopis sp. forest  [PDF]

Abstract:

Advances in genotyping technology, such as molecular markers, have noticeably improved our capacity to characterize genomes at multiple loci. Concomitantly, the methodological framework to analyze genetic data has expanded, and keeping abreast with the latest statistical developments to analyze molecular marker data in the context of spatial genetics has become a difficult task. Most methods in spatial statistics are devoted to univariate data whereas the nature of molecular marker data is highly dimensional. Multivariate methods are aimed at finding proximities between entities characterized by multiple variables by summarizing information in few synthetic variables. In particular, Principal Component analysis (PCA) has been used to study genetic structure of geo-referenced allele frequency profiles, incorporating spatial information with a posteriori analysis. Conversely, the recently developed spatially restricted PCA (sPCA) explicitly includes spatial data in the optimization criterion. In this work, we compared the results of the application of PCA and sPCA in the study of the spatial genetic structure at fine scale of a Prosopis flexuosa and P. chilensis hybrid swarm. Data consisted in the genetic characterization of 87 trees sampled in Córdoba, Argentina and genotyped at six microsatellites, which yielded 72 alleles. As expected, principal components explained more variance than sPCA components, but were less spatially autocorrelated. The maps obtained by the interpolation of sPC1 values allowed a better visualization of a patchy spatial pattern of genetic variability than the PC1 synthetic map. We also proposed a PC-sPC scatter plot of allele loadings to better understand the allele contributions to spatial genetic variability.

Recognition in the Communication Processes of Diverse Young the Experience of Living in a Park in the City of Cali  [PDF]
Mónica Marión Cata？o
Advances in Journalism and Communication (AJC) , 2015, DOI: 10.4236/ajc.2015.31004
Abstract: Artisan Park La Loma de la Cruz, is a park located in a suburb of the city of Cali, a place where different groups converge youth from youth cultures. The park is a place for meeting, socializing, communication practices through which young people interact and build relationships. The park is set up as a stage of “coexistence” in which rockers, punks, emos, skaters and members of the LGBTI community stay together and share the same dwelling place (Figure 1). In the worlds of life of these young people, the words in different languages are a part of his being and his feelings, hence the affectations of joy and sadness, as defined by Spinoza (1980)1, are a way of weaving links and establish relationships communication. It is also possible to identify forms of recognition, Honneth’s way, recognition of love and solidarity2. These forms of recognition collide when young people, relate to the adult world, in the park, are made by artisans, police and neighbors. From the adult world, the form of contempt is evident in the rejection of the young by their expressions, especially those with expressing his affectations manifest. If young people recognize the existence of other people, as well as their own differences in the way they think, if they recognize the action in their own inter-subjective relationships and in the same way they construct a “we”, we would be spectators of new ways of being together; of ethical and political linking which go through new ways of living together and in which the sense and the shared meaning of life are negotiated that show a way of understanding in communication.
An Experimental Study of Self-Compacting Concrete Made with Filler from Construction and Demolition Waste  [PDF]
M？nica Batista Leite, Marcela Crusoé Figueiredo
Open Journal of Civil Engineering (OJCE) , 2020, DOI: 10.4236/ojce.2020.104028
Abstract: This study evaluated the influence of the Portland cement replacement by 0, 5%, 10%, 15% and 20% of Construction and Demolition Waste (CDW) filler contents in the production of self-compacting concrete (SCC). The SCC mixtures were evaluated on fresh state by slump flow, J-ring, resistance of segregation, specific gravity, and on hardened state by compressive and splitting tensile strength, specific gravity, air voids and absorption rate. The results indicated that all SCC produced with CDW filler met the limits established at any level of substitution without changes of the w/c ratio or superplasticizer content. It was possible to verify that the presence of CDW filler, in substitution of cement, by volume, improves the resistance to segregation and up to 5% of CDW filler decreases the loss of fluidity with time as compared to reference. It was found that all SCC mixtures, at 28 days, had the average compressive strength above 50 MPa, without showing significant loss with up to 20% of CDW filler. For splitting tensile strength, SCC recycled mixtures reached up to 92.5% of the SCC used as reference. Absorption rate and air voids index of SCC recycled mixtures had a maximum increase of 1.60%Compared to the reference one. So, it is possible to conclude that the use of the CDW filler up to 20% in substitution of cement, by volume, is feasible for SCC production.
Co-infec？？o HIV/tuberculose: necessidade de uma vigilancia mais efetiva
Lima,M？nica M.;
Revista de Saúde Pública , 1997, DOI: 10.1590/S0034-89101997000300001
Abstract: the increasing endemicity of tuberculosis resulting from causes such as immigration, poverty, a declining public health infrastructure and co-infection by hiv/mycobacterium tuberculosis, is leading to a change in tuberculosis control programmes. one of the main reasons for the resurgence of tuberculosis is hiv infection - the risk of tuberculosis is greater in hiv patients than in the majority of the population as can be seen from numerous research projects. the need for systematic testing for hiv infection in all tuberculosis patients by undertaking confidential hiv tests on admission to a tuberculosis programme is brought out. this measure would increase the number of cases diagnosed and provide data for better surveillance of the co-infection.
