Research model for farm building design: General structure and physiognomic characterization phase

The design of contemporary farm buildings often subordinates architectural quality and aesthetic features to economic aspects, thus leading to poor landscape consistency and compatibility.  The research presented in this paper is based on the theoretical principle that historic rural buildings, being expression of an accumulation of empirical knowledge broadly associated with high architectural quality, have remarkable potentials to contribute with useful elements to the design of contemporary buildings, and on the awareness that the design process is also necessarily and substantially determined by technological, economic and functional variables.  The paper presents the FarmBuiLD model (Farm Building Landscape Design), a research model proposed by the authors as a tool for the analysis of the architectural characteristics of both historical and contemporary rural buildings, as well as the meta-design of new construction and transformation of contemporary rural buildings.  In particular, the work focuses on the general structure of this model and a synthesis of the main results of the critical analysis of the scientific literature aimed at identifying a set of synthetic architectural parameters suitable for its implementation, through the interpretation of the main physiognomical characteristics of rural buildings.  These parameters are not meant as a tool to obtain quantitative data to be translated into design constraints automatically; on the contrary, they are mainly considered as an interpretive-analytical tool, part of a broader knowledge framework aimed at supporting, stimulating and suggesting the design choices.Keywords: Rural building design, historical-typological consistency, landscape compatibility, architectural quality, analytical and meta-design criteria, Italian rural building heritage Citation: Tassinari P, D.

Feeding strategy and ontogenetic changes in diet of gurnards (Teleostea: Scorpaeniformes: Triglidae) from the Adriatic Sea

A multi-specific approach in fish diet studies provides insight into the complexity of trophic interactions in marine communities. The feeding habits of three gurnard species, Aspitrigla cuculus, Chelidonichthys lucerna and Eutrigla gurnardus (Scorpaeniformes: Triglidae), from the north-middle Adriatic Sea were studied to evaluate prey-resource partitioning amongst species and within species, comparing juveniles' and adults' diet for each gurnard species. A total of 1818 specimens (390 A. cuculus, 973 C. lucerna, 455 E. gurnardus) were collected by bottom trawling and they were assigned to size classes (juveniles or adults) on the basis of macroscopic evaluation of the gonads. Stomach contents were analysed. A common dietary preference for Crustacea was found in all species and size classes considered. Nevertheless, gurnards showed distinct feeding behaviour: C. lucerna and E. gurnardus were generalist-opportunistic predators, showing a varied diet based on epi-benthic, bentho-pelagic and necto-benthic preys belonging to different taxa such as Teleostei and Mollusca, while A. cuculus may be considered a specialist feeder, feeding almost exclusively on necto-benthic invertebrates. Morisita's index calculated for critical size classes (juveniles and adults) pointed out differences. At the inter-specific level, possible dietary competition between A. cuculus and E. gurnardus (C > 0.65) was found for all size classes combined, due to the prey abundance of Lophogaster typicus (Crustacea: Mysida). At the intra-specific level, high diet overlap was found between juveniles and adults of C. cuculus (C = 0.98) and between juveniles and adults of E. gurnardus (C > 0.84). In contrast, C. lucerna did not compete with increasing body size (C < 0.20), showing a clear change from crustaceans to fish in its diet preferences. The possibility that A. cuculus and E. gurnardus may compete for the same prey resources while C. lucerna shows food resource partitioning is discussed. Better understanding of the ecology of these coexisting predators should lead to improved conservation and improved fisheries management

Analysis of Phenotypic Variability and Correlation on Sugar Content Contributing Phenotypes of Salak (Salacca sumatrana Reinw var.Sidempuan. ) under Various Altitudes

Salak (Salacca edulis), commonly known as snake fruit, is one of Indonesia's local fruit preference with a promising commercial prospect for the development of horticultural product. This fruit is a superior fruit commodity of Padang Sidempuan which has been recognized nationally. A significant change of geographical altitudes from lowland to highland supported the salak growth when planted in South Tapanuli. This study was aimed to evaluate the phenotypic variability as well as its correlation of salak planted in three different subdistricts of South Tapanuli representing low, mid and highlands. Sampling was conducted using purposive sampling method where 30 accessions of salak were collected from all those three subdistricts in South Tapanuli. Both qualitative and quantitative traits were statistically analyzed and evaluated for its phylogenetic using NTSYS 2.02. According to the phylogenetic analysis, 37 morphological traits resulted in a similarity coefficient ranging from 0.34-0.68. Of all accessions tested, two accessions (MC4 and MC5) were closely clustered with a coefficient of 0.68. Moreover, 7 traits were positively correlated to sugar content, including plant height,number of fruit bunch, length and width of leaflet, number of leaf, fruit weight and flesh thickness

Peranan Penyidik Kepolisian Resor Siak Dalam Mengungkap Tindak Pidana Menggunakan Senjata Api

In the beginning the use of firearms is only allowed for certain apparatus with the provisions and controls are tight, especially in the field of defence and security. As the development era that has begun to lack of surveillance conducted by law enforcement officers in cracking down on rampant circulation up illegal firearms that have been circulating in the community, which resulted in the occurrence of the crime using firearms. Licensing the ownership of firearms have been regulated in such a way in terms of legislation. Based on the description that has been described above, the author argues for the analytically descriptive regarding the role of the investigating of the Siak Resort Police in exposing the crime using firearms.This legal research suggests the outline of three problems as follows: 1) how did the Siak Resort Police investigator's role in exposing the crime using firearms?, 2) what are the obstacles of the Siak Resort Police investigator in exposing the crime using firearms?, and 3) how the Siak Resort Police investigator attempt to overcome the obstacles in exposing the crime using firearms? This research use sociological, juridical methods which are: applying research approaches to the study of perception and behavior of legal persons (human and legal entity) and the community as well as the effectiveness of the enactment of positive law in the community, where the author direct research on the location or place that is examined in order to give a complete and clear picture of the problems in a thorough the Siak Resort Police investigator's role in uncovering the crime using firearms.Legal research is then analyzed the role of the Siak Resort Police investigator in exposing the crime using firearms where the leading sector on Reserse Criminal Unit (Satreskrim) at the Siak Resort Police (Polres Siak) and coordinate with other entities such as the Security Intelligence Unit (Satintelkam) and the active participation of all elements of society, the obstacles encountered is the number of elements in the community who still feel frightened to report any event or incident a criminal offence who uses a firearm, and concrete efforts made by Police investigators, among others in the form of the Siak Resort Police construction and/or socialization to all elements of society to improve environmental safety systems in order to cope with the increasing swakarsa crime using firearms

Temporal genetic structure in a poecilogonous polychaete: the interplay of developmental mode and environmental stochasticity

Background: Temporal variation in the genetic structure of populations can be caused by multiple factors, including natural selection, stochastic environmental variation, migration, or genetic drift. In benthic marine species, the developmental mode of larvae may indicate a possibility for temporal genetic variation: species with dispersive planktonic larvae are expected to be more likely to show temporal genetic variation than species with benthic or brooded non-dispersive larvae, due to differences in larval mortality and dispersal ability. We examined temporal genetic structure in populations of Pygospio elegans, a poecilogonous polychaete with within-species variation in developmental mode. P. elegans produces either planktonic, benthic, or intermediate larvae, varying both among and within populations, providing a within-species test of the generality of a relationship between temporal genetic variation and larval developmental mode. Results: In contrast to our expectations, our microsatellite analyses of P. elegans revealed temporal genetic stability in the UK population with planktonic larvae, whereas there was variation indicative of drift in temporal samples of the populations from the Baltic Sea, which have predominantly benthic and intermediate larvae. We also detected temporal variation in relatedness within these populations. A large temporal shift in genetic structure was detected in a population from the Netherlands, having multiple developmental modes. This shift could have been caused by local extiction due to extreme environmental conditions and (re)colonization by planktonic larvae from neighboring populations. Conclusions: In our study of P. elegans, temporal genetic variation appears to be due to not only larval developmental mode, but also the stochastic environment of adults. Large temporal genetic shifts may be more likely in marine intertidal habitats (e.g. North Sea and Wadden Sea) which are more prone to environmental stochasticity than the sub-tidal Baltic habitats. Sub-tidal and/or brackish (less saline) habitats may support smaller P. elegans populations and these may be more susceptible to the effects of random genetic drift. Moreover, higher frequencies of asexual reproduction and the benthic larval developmental mode in these populations leads to higher relatedness and contributes to drift. Our results indicate that a general relationship between larval developmental mode and temporal genetic variation may not exist

Topological Wilson-loop area law manifested using a superposition of loops

We introduce a new topological effect involving interference of two meson loops, manifesting a path-independent topological area dependence. The effect also draws a connection between quark confinement, Wilson-loops and topological interference effects. Although this is only a gedanken experiment in the context of particle physics, such an experiment may be realized and used as a tool to test confinement effects and phase transitions in quantum simulation of dynamic gauge theories.Comment: Superceding arXiv:1206.2021v1 [quant-ph
