Full Text Available The different contemporary approaches that touches the development focus from the territorial perspective can be classified into two big surveys of the so called new regionalism: the globalist survey and the regionalist survey. Some authors have preferred to focus on the regionalist studies in an excessively optimistic way, this way deserving being critically analysed. In spite of all that, it is possible to visualize a scenery of breathing answers to the challenges of the development territorialization in a way that the different forms of social territorial organization, the territorial collective innovation and the necessary reconsideration of the State´s role deserve destak. This way, it is opened the possibility that the progressive trajectory of territorial development can be managed and administrated from the articulated action of public and private actors.

2009-06-01

Full Text Available It is now generally accepted that chromosomes in the cell nucleus are organized in distinct domains, first called chromosome territories in 1909 by the great cytologist Theodor Boveri. Yet, even today chromosomes have remained enigmatic individuals, whose structures, arrangements and functions in cycling and post-mitotic cells still need to be explored in full detail. Whereas numerous recent reviews describe present evidence for a dynamic architecture of chromosome territories and discuss the potential significance within the functional compartmentalization of the nucleus, a comprehensive historical account of this important concept of nuclear organization was lacking so far. Here, we describe the early rise of chromosome territories within the context of the discovery of chromosomes and their fundamental role in heredity, covering a period from the 1870th to the early 20th century (part I, this volume. In part II (next volume we review the abandonment of the chromosome territory concept during the 1950th to 1980th and the compelling evidence, which led to its resurrection during the 1970th to 1980th.

COMPARATIVE ANALYSIS OF EFFICIENCY FUNCTIONING OF THE CONTROLLER-MELIORATIVE ORGANIZATION OF THE TERRITORY IN UKRAINE AND THE USA

Butenko E.

2017-08-01

Full Text Available In order to create an optimal land use model and reduce the impact of erosion on agricultural land, a number of land conservation measures need to be introduced. The most effective set of measures that minimizes the manifestation of water erosion in erosion-hazardous areas is the contouring-reclamation organization of the territory. This complex of activities combines a protective reclamation structure that interacts with the terrain and soil protection technology of growing crops. In general, at the end of the 1980s, projects of contouring-reclamation organization of the territory were developed for sites that had a negative erosion effect throughout the territory of Ukraine. However, with the beginning of the 1990s, the practical implementation of measures to restructure the territory was suspended due to political transformations and lack of funds. In practice, one of the most striking examples of the implementation of design decisions is the territory of Lisnosankivsky village council of the Kupyansk district, whose Kharkiv territory is characterized by significant manifestations of erosion. For three decades, the staff of the soil protection laboratory conducted experiments on these sites. The possibility of achieving sustainable ecological indicators of soil erosion at field crop rotation -1.8 t / ha and soil protection crop rotation -1.5 t / ha was established. Similar objects that were implemented and implemented in the Kupyansk district of the Kharkiv region, were partially implemented on other erosion-hazardous sites in Polissya, Forest-steppe and Steppe regions of Ukraine. Today, most of these activities have exhausted their laid-out exploitation resources, some of the protected areas were destroyed as a result of the lack of state control, constant change of owners and the lack of motivation of actual land users. The negative manifestation of water erosion on arable land is characteristic not only for the territory of Ukraine. This

Territorial prevention of natural disasters. Campania Region: a high risk territory. Studies by PLINIVS Centre and open issues

Full Text Available The safety of the territory and the environment is a theme much discussed, but often not in organic and competent way. PLINIVS study centre has been studying for several years the impact of potentially disastrous events on the territory and has produced analysis models and scenery simulation of main natural risks regarding Campania territory (seismic, hydrogeological, volcanic, meteo-marine risks, etc.. Knowing the risk, and quantifying it, is important in order to single out critical aspects of the territory (threats and to intervene through mitigation measures and eventually a modern Plan of Civil Protection. Therefore the plan becomes a dynamic process able to control rhythmically the state of the risk and the safety level of the territory, and spatial planning should avail itself of the fundamental contribution of knowledge offered by these tools.

Tactile spatial working memory activates the dorsal extrastriate cortical pathway in congenitally blind individuals.

In sighted individuals, both the visual and tactile version of the same spatial working memory task elicited neural responses in the dorsal "where" cortical pathway (Ricciardi et al., 2006). Whether the neural response during the tactile working memory task is due to visually-based spatial imagery or rather reflects a more abstract, supramodal organization of the dorsal cortical pathway remains to be determined. To understand the role of visual experience on the functional organization of the dorsal cortical stream, using functional magnetic resonance imaging (fMRI) here we examined brain response in four individuals with congenital or early blindness and no visual recollection, while they performed the same tactile spatial working memory task, a one-back recognition of 2D and 3D matrices. The blind subjects showed a significant activation in bilateral posterior parietal cortex, dorsolateral and inferior prefrontal areas, precuneus, lateral occipital cortex, and cerebellum. Thus, dorsal occipito-parietal areas are involved in mental imagery dealing with spatial components in subjects without prior visual experience and in response to a non-visual task. These data indicate that recruitment of the dorsal cortical pathway in response to the tactile spatial working memory task is not mediated by visually-based imagery and that visual experience is not a prerequisite for the development of a more abstract functional organization of the dorsal stream. These findings, along with previous data indicating a similar supramodal functional organization within the ventral cortical pathway and the motion processing brain regions, may contribute to explain how individuals who are born deprived of sight are able to interact effectively with the surrounding world.

Two different streams form the dorsal visual system: anatomy and functions.

Science.gov (United States)

Rizzolatti, Giacomo; Matelli, Massimo

2003-11-01

There are two radically different views on the functional role of the dorsal visual stream. One considers it as a system involved in space perception. The other is of a system that codes visual information for action organization. On the basis of new anatomical data and a reconsideration of previous functional and clinical data, we propose that the dorsal stream and its recipient parietal areas form two distinct functional systems: the dorso-dorsal stream (d-d stream) and the ventro-dorsal stream (v-d stream). The d-d stream is formed by area V6 (main d-d extrastriate visual node) and areas V6A and MIP of the superior parietal lobule. Its major functional role is the control of actions "on line". Its damage leads to optic ataxia. The v-d stream is formed by area MT (main v-d extrastriate visual node) and by the visual areas of the inferior parietal lobule. As the d-d stream, v-d stream is responsible for action organization. It, however, also plays a crucial role in space perception and action understanding. The putative mechanisms linking action and perception in the v-d stream is discussed.

Lumbar dorsal ramus syndrome.

Science.gov (United States)

Bogduk, N

1980-11-15

Low back pain, referred pain in the lower limbs, and spasm of the back, gluteal, and hamstring muscles are clinical features which can be induced in normal volunteers by stimulating structures which are innervated by the lumbar dorsal rami. Conversely, they can be relieved in certain patients by selective interruption of conduction along dorsal rami. These facts permit the definition of a lumbar dorsal ramus syndrome, which can be distinguished from the intervertebral disc syndrome and other forms of low back pain. The distinguishing feature is that, in lumbar dorsal ramus syndrome, all the clinical features are exclusively mediated by dorsal rami and do not arise from nerve-root compression. The pathophysiology, pathology, and treatment of this syndrome are described. Recognition of this syndrome, and its treatment with relatively minor procedures, can obviate the need for major surgery which might otherwise be undertaken.

Adult cut dorsal root axons regenerate into the transplants of embryonic spinal cord (ESC) and form functional synapses within the transplants. It is unknown whether the growth is specific to transplants of dorsal half of ESC, a normal target of most dorsal root axons, or whether it is due to properties shared by transplants of ventral half of ESC. We used calcitonin gene-related peptide (CGRP) immunohistochemistry to label to the subpopulations of regenerated adult dorsal root axons, quantit...

A Fate Map of the Murine Pancreas Buds Reveals a Multipotent Ventral Foregut Organ Progenitor

Angelo, Jesse R.; Guerrero-Zayas, Mara-Isel; Tremblay, Kimberly D.

2012-01-01

The definitive endoderm is the embryonic germ layer that gives rise to the budding endodermal organs including the thyroid, lung, liver and pancreas as well as the remainder of the gut tube. DiI fate mapping and whole embryo culture were used to determine the endodermal origin of the 9.5 days post coitum (dpc) dorsal and ventral pancreas buds. Our results demonstrate that the progenitors of each bud occupy distinct endodermal territories. Dorsal bud progenitors are located in the medial endoderm overlying somites 2–4 between the 2 and 11 somite stage (SS). The endoderm forming the ventral pancreas bud is found in 2 distinct regions. One territory originates from the left and right lateral endoderm caudal to the anterior intestinal portal by the 6 SS and the second domain is derived from the ventral midline of the endoderm lip (VMEL). Unlike the laterally located ventral foregut progenitors, the VMEL population harbors a multipotent progenitor that contributes to the thyroid bud, the rostral cap of the liver bud, ventral midline of the liver bud and the midline of the ventral pancreas bud in a temporally restricted manner. This data suggests that the midline of the 9.5 dpc thyroid, liver and ventral pancreas buds originates from the same progenitor population, demonstrating a developmental link between all three ventral foregut buds. Taken together, these data define the location of the dorsal and ventral pancreas progenitors in the prespecified endodermal sheet and should lead to insights into the inductive events required for pancreas specification.

Schreiter, Jeannine

2017-07-01

Full Text Available Background/purpose: The use of dorsal skinfold chamber models has substantially improved the understanding of micro-vascularisation in pathophysiology over the last eight decades. It allows pathophysiological studies of vascularisation over a continuous period of time. The dorsal skinfold chamber is an attractive technique for monitoring the vascularisation of autologous or allogenic transplants, wound healing, tumorigenesis and compatibility of biomaterial implants. To further reduce the animals’ discomfort while carrying the dorsal skinfold chamber, we developed a smaller chamber (the Leipzig Dorsal Skinfold Chamber and summarized the commercial available chamber models. In addition we compared our model to the common chamber. Methods: The Leipzig Dorsal Skinfold Chamber was applied to female mice with a mean weight of 22 g. Angiogenesis within the dorsal skinfold chamber was evaluated after injection of fluorescein isothiocyanate dextran with an Axio Scope microscope. The mean vessel density within the dorsal skinfold chamber was assessed over a period of 21 days at five different time points. The gained data were compared to previous results using a bigger and heavier dorsal skinfold model in mice. A PubMed and a patent search were performed and all papers related to “dorsal skinfold chamber” from 1 of January 2006 to 31 of December 2015 were evaluated regarding the dorsal skinfold chamber models and their technical improvements. The main models are described and compared to our titanium Leipzig Dorsal Skinfold Chamber model.Results: The Leipzig Dorsal Skinfold Chamber fulfils all requirements of continuous models known from previous chamber models while reducing irritation to the mice. Five different chamber models have been identified showing substantial regional diversity. The newly elaborated titanium dorsal skinfold chamber may replace the pre-existing titanium chamber model used in Germany so far, as it is smaller and lighter

The architecture of chicken chromosome territories changes during differentiation

Stadler Sonja

2004-11-01

Full Text Available Abstract Background Between cell divisions the chromatin fiber of each chromosome is restricted to a subvolume of the interphase cell nucleus called chromosome territory. The internal organization of these chromosome territories is still largely unknown. Results We compared the large-scale chromatin structure of chromosome territories between several hematopoietic chicken cell types at various differentiation stages. Chromosome territories were labeled by fluorescence in situ hybridization in structurally preserved nuclei, recorded by confocal microscopy and evaluated visually and by quantitative image analysis. Chromosome territories in multipotent myeloid precursor cells appeared homogeneously stained and compact. The inactive lysozyme gene as well as the centromere of the lysozyme gene harboring chromosome located to the interior of the chromosome territory. In further differentiated cell types such as myeloblasts, macrophages and erythroblasts chromosome territories appeared increasingly diffuse, disaggregating to separable substructures. The lysozyme gene, which is gradually activated during the differentiation to activated macrophages, as well as the centromere were relocated increasingly to more external positions. Conclusions Our results reveal a cell type specific constitution of chromosome territories. The data suggest that a repositioning of chromosomal loci during differentiation may be a consequence of general changes in chromosome territory morphology, not necessarily related to transcriptional changes.

2013-12-01

Full Text Available Two recently published books, one from Spain (Muñoz Machado, 2012 and the other from Colombia (Mendoza Martelo, 2013, evince concerns with respect to the territorial organization in both countries. What is the appeal of the territorial model? With common constitutional errors occurring in the territorial area, and a crisis in both function and coordination in various levels of the Government –as well as in the different regions and autonomous communities–, is legal reform preferable to constitutional change? These are some of the issues raised and evaluated in current debates. In the work in question, the main problems in Spain are analyzed and the author proposes ways of solving or diminishing these problems, such as a return to centralism, the partial conservation of autonomous communities, the replacement of the current model with a federal State, as well as the possibilities of self-determination and separatism. The proposed study will serve to revise certain aspects of Colombia’s territorial system, in order to determine whether or not reformation is necessary.

The Political and Territorial Development of Nations without States

Directory of Open Access Journals (Sweden)

Jernej Zupančič

2010-12-01

Full Text Available This paper analyzes the issue of nations without states in contemporary Europe between the Atlantic and the Urals. The political map of the continent comprises forty-seven countries, most of which are nation-states. However, the cultural mosaic of Europe is far more complex; there are around fifty ethnic groups (in addition to historical, territorial, or indigenous ethnic minorities and an enormous number of immigrant ethnic communities lacking a state-based organization. Together, these people add up to 78 million, or almost 15% of the European population. Twenty-seven groups can be considered nations without states; they are culturally and ethnically based and have various forms of territorial integrity and political organization. However, they did not create a state organization, despite many attempts by some through history. Without a state organization, those communities have poorer opportunities to protect their folk culture and to reproduce various elements of ethnic identity. This is why they seek territorial autonomy or independent statehood through nationalist movements. In many cases, these ambitions are encompassed in regional movements. These movements have been popular in Europe, particularly because the idea of a “Europe of regions” as part of the European Union has had broad political support and acceptance. However, it has not actually succeeded. The EU and Europe as a whole are still a Europe of (nation-states. In general, regional movements have been successful and through this some nations without states have attained part of their political ambitions in the form of territorial autonomy. The regionalization of former centralist states (e.g., Spain and the United Kingdom increased the chances of ethnic survival for the Catalans, Basques, Scots, and Welsh. On the other hand, the regionalization of nations without states represented territorial division, a kind of “divide and rule” strategy serving to reduce their

Full Text Available This article discusses how territory and linking notions articulate with the health field in Brazil, in view of the relations that are established between health staff and certain social groups who see in the movement a logic of life, survival and resistance: the nomads. The concept of territory is an important organizer of Brazilian’s public policies, and is closely related to inclusion. The data were collected through participant observation of the daily work of two teams of Family Health Strategy, in a medium-sized city located in the state of Rio Grande do Sul. For these services, nomadism is seen as a nuisance. On the other hand, include not only acquires a sense of attachment and population control, but the demarcation of belonging territories, from the investment of the relation of users with health services.

To investigate the versatility of the ventral urethrotomy approach in bulbar reconstruction with buccal mucosa (BM) grafts placed on the dorsal, ventral or dorsal plus ventral urethral surface. Between 1999 and 2008, 216 patients with bulbar strictures underwent BM graft urethroplasty using the ventral-sagittal urethrotomy approach. Of these patients, 32 (14.8%; mean stricture 3.2 cm, range 1.5-5) had a dorsal graft urethroplasty (DGU), 121 (56%; mean stricture 3.7, range 1.5-8) a ventral graft urethroplasty (VGU), and 63 (29.2%; mean stricture 3.4, range 1.5-10) a dorsal plus ventral graft urethroplasty (DVGU). The strictured urethra was opened by a ventral-sagittal urethrotomy and BM graft was inserted dorsally or ventrally or dorsal plus ventral to augment the urethral plate. The median follow-up was 37 months. The overall 5-year actuarial success rate was 91.4%. The 5-year actuarial success rates were 87.8%, 95.5% and 86.3% for the DGU, VGU and DVGU, respectively. There were no statistically significant differences among the three groups. Success rates decreased significantly only with a stricture length of >4 cm. In BM graft bulbar urethroplasties the ventral urethrotomy access is simple and versatile, allowing an intraoperative choice of dorsal, ventral or combined dorsal and ventral grafting, with comparable success rates.

Full Text Available This article aims to argue that territory is ahistorical concept rather than a constant one in explaining political conception of state and other political entities. Referring to liberalism and political realism, territory has been one of the core concepts in the study of political science. This paper will then elaborate the concept of territoriality and its problem in the era of globalization, which will also describe the existence of territory of non-state actor in private and public sphere. At the end of this article, I will outline the possibility to have a different reaction against the threat of non-state actor when the notion of territory is not taken for granted anymore.

2017-04-01

The purpose of this study is to compare radiographic outcomes of patients treated with dorsal spanning plates with previously reported normal values of radiographic distal radius anatomy and compare the results with prior publications for both external fixation and internal fixation with volar locked plates. Patients with complex distal radius fractures including dorsal marginal impaction pattern necessitating dorsal distraction plating at the discretion of the senior authors (M.A.T. and M.A.I.) from May 30, 2013, to December 29, 2015, were identified and included in the study. Retrospective chart and radiograph review was performed on 19 patients, 11 male and 8 female, with mean age of 47.83 years (22-82). No patients were excluded from the study. All fractures united prior to plate removal. The average time the plate was in place was 80.5 days (49-129). Follow-up radiographs showed average radial inclination of 20.5° (13.2°-25.5°), radial height of 10.7 mm (7.5-14 mm), ulnar variance of -0.3 mm (-2.1 to 3.1 mm), and volar tilt of 7.9° (-3° to 15°). One patient had intra-articular step-off greater than 2 mm. Dorsal distraction plating of complex distal radius fractures yields good radiographic results with minimal complications. In cases of complex distal radius fractures including dorsal marginal impaction where volar plating is not considered adequate, a dorsal distraction plate should be considered as an alternative to external fixation due to reduced risk for infection and better control of volar tilt.

Ontogeny of osmoregulation in embryos of intertidal crabs (Hemigrapsus sexdentatus and H. crenulatus, Grapsidae, Brachyura): putative involvement of the embryonic dorsal organ.

Seneviratna, Deepani; Taylor, H H

2006-04-01

This study examined whether the existence of hyperosmotic internal fluids in embryos of euryhaline crabs (Hemigrapsus sexdentatus and H. crenulatus) in dilute seawater reflects osmotic isolation due to impermeability of the egg envelope, as proposed for other decapods, or active osmoregulation. When ovigerous crabs with eggs at gastrula stage were transferred from 100% seawater (osmolality 1000 mmol kg(-1)) to 50% seawater, embryogenesis and hatching of zoea were completed normally, but were delayed. Hatching failed if the transfer to 50% seawater occurred before gastrulation, and embryogenesis was abnormal in 25% seawater. In 100% seawater, embryos at all stages were internally hyperosmotic by 150-250 mmol kg(-1). On transfer to 50% seawater, osmolality initially decreased but remained 200-350 mmol kg(-1) hyperosmotic to the medium for several weeks until hatching. High efflux rates of tritium-labelled water (t((1/2)) 16-75 min) and (22)Na (t(1/2) 109-374 min) from H. crenulatus embryos were inconsistent with the osmotic isolation hypothesis. It is concluded that post-gastrula embryos were actively hyper-osmoregulating. The diffusional water permeability of the embryos decreased during development while the sodium efflux rate increased 10-fold. Very rapidly exchanging pools of water and sodium (t(1/2) a few seconds to minutes) probably corresponded to peri-embryonic fluid and implied that the egg envelope was a negligible barrier to diffusion of water and salts. Higher Na(+)/K(+)-ATPase activities in late embryos of H. crenulatus incubated in 50% seawater than in embryos incubated in full strength seawater were consistent with an acclimation response. An area of the embryonic surface located over the yolk in the region of the embryonic dorsal organ stained with AgNO(3). Staining appeared at gastrulation, persisted throughout development and was lost at hatching. Deposits of AgCl between the outer and inner membranes, identified by X-ray microanalysis, suggest that

Prey availability affects territory size, but not territorial display behavior, in green anole lizards

The availability of food resources can affect the size and shape of territories, as well as the behaviors used to defend territories, in a variety of animal taxa. However, individuals within a population may respond differently to variation in food availability if the benefits of territoriality vary among those individuals. For example, benefits to territoriality may differ for animals of differing sizes, because larger individuals may require greater territory size to acquire required resources, or territorial behavior may differ between the sexes if males and females defend different resources in their territories. In this study, we tested whether arthropod abundance and biomass were associated with natural variation in territory size and defense in insectivorous green anole lizards, Anolis carolinensis. Our results showed that both male and female lizards had smaller territories in a habitat with greater prey biomass than lizards in habitats with less available prey, but the rates of aggressive behaviors used to defend territories did not differ among these habitats. Further, we did not find a relationship between body size and territory size, and the sexes did not differ in their relationships between food availability and territory size or behavioral defense. Together, these results suggest that differences in food availability influenced male and female territorial strategies similarly, and that territory size may be more strongly associated with variation in food resources than social display behavior. Thus, anole investment in the behavioral defense of a territory may not vary with territory quality.

To compare both the dorsal onlay technique of Barbagli and the dorsal inlay technique of Asopa for the management of long anterior urethral stricture. From January 2010 to May 2012, a total of 47 patients with long anterior urethral strictures were randomized into two groups. The first group included 25 patients who were managed by dorsal onlay buccal mucosal graft urethroplasty. The second group included 22 patients who were managed by dorsal inlay buccal mucosal graft urethroplasty. Different clinical parameters, postoperative complications and success rates were compared between both groups. The overall success rate in the dorsal onlay group was 88%, whereas in the dorsal inlay group the success rate was 86.4% during the follow-up period. The mean operative time was significantly longer in the dorsal onlay urethroplasty group (205 ± 19.63 min) than in the dorsal inlay urethroplasty group (128 ± 4.9 min, P-value <0.0001). The average blood loss was significantly higher in the dorsal onlay urethroplasty group (228 ± 5.32 mL) than in the dorsal inlay urethroplasty group (105 ± 12.05 mL, P-value <0.0001). The dorsal onlay technique of Barbagli and the dorsal inlay technique of Asopa buccal mucosal graft urethroplasty provide similar success rates. The Asopa technique is easy to carry out, provides shorter operative time and less blood loss, and it is associated with fewer complications for anterior urethral stricture repair. © 2013 The Japanese Urological Association.

As the recent law on energy transition defined a legal framework which allowed the action of local authorities in the field of energy, and resulted in the creation of local or territorial energy utilities by these authorities or other actors, this report proposes a presentation of examples of territorial energy utilities or operators. These examples are chosen in different French towns, district or regions (Vienne, Montpellier, Lannion, Pays de Vilaine, Lot, Ile-de-France, Rhone-Alpes) but also in Germany and Austria. Before presenting these experiments, the authors describe and discuss the French legal framework of territorial energy transition. They describe the territorial energy operator as a factor of emergence of an energetic and territorial autonomy

TERRITORIES, TERRITORIALITIES AND IDENTITIES: MATERIAL RELATIONS, SYMBOLIC, AND OF GENDER IN THE COUNTRYSIDE

Lívia Aparecida Pires de

2017-06-01

Full Text Available The territory is understood as an appropriate space, delimitated by power relations, and constituted by material and symbolic relations which provide elements to the territorialities development and for forming men and women identities. In the territory of familiar production, the sexual division of labor and of spaces causes the 'invisibility' of women's work in the productive sphere, fact that influences on the construction of the rural women’s identity. However, women exercise their territorialities in both spaces and their productive and reproductive activities are fundamental to the family's livingness and permanence in the countryside. In this sense, it proposes to analyze the territorialities and the territorial identity of the subjects of the countryside and ascertain how this discussion contributes to the recognition of rural woman's identity. To the development of this research, have been taken theoretical research about: territory, territoriality, identity, gender and domestic space.

The functional anatomy of speech perception: Dorsal and ventral processing pathways

Science.gov (United States)

Hickok, Gregory

2003-04-01

Drawing on recent developments in the cortical organization of vision, and on data from a variety of sources, Hickok and Poeppel (2000) have proposed a new model of the functional anatomy of speech perception. The model posits that early cortical stages of speech perception involve auditory fields in the superior temporal gyrus bilaterally (although asymmetrically). This cortical processing system then diverges into two broad processing streams, a ventral stream, involved in mapping sound onto meaning, and a dorsal stream, involved in mapping sound onto articulatory-based representations. The ventral stream projects ventrolaterally toward inferior posterior temporal cortex which serves as an interface between sound and meaning. The dorsal stream projects dorsoposteriorly toward the parietal lobe and ultimately to frontal regions. This network provides a mechanism for the development and maintenance of ``parity'' between auditory and motor representations of speech. Although the dorsal stream represents a tight connection between speech perception and speech production, it is not a critical component of the speech perception process under ecologically natural listening conditions. Some degree of bi-directionality in both the dorsal and ventral pathways is also proposed. A variety of recent empirical tests of this model have provided further support for the proposal.

The territorial biorefinery as a new business model

2016-05-01

Full Text Available The transition toward more sustainable industries opens the way for alternative solutions based upon new economic models using agricultural inputs or biomass to substitute oil-based inputs. In this context different generations of biorefinery complexes are evolving rapidly and highlight the numerous possibilities for the organization of processing activities, from supply to final markets. The evolution of these biorefineries has followed two main business models, the port biorefinery, based on the import of raw materials, and the territorial biorefinery, based on strong relationships with local (or regional supply bases. In this article we focus on the concept of the ‘territorial biorefinery’, seen as a new business model. We develop the idea of a link between the biorefinery and its territory through several relevant theoretical approaches and demonstrate that the definition of ‘territorial biorefinery’ does not achieve, from these theoretical backgrounds, a consensus. More importantly, we emphasise that the theoretical assumptions underlying the different definitions used should be made explicit in order to facilitate the manner in which practioners study, develop and set up businesses of this kind.

Full Text Available The 1999 Constitution of the Bolivarian Republic of Venezuela (CBRV recognizes Indigenous Rights; among them, the territorial claims. In agreement with what is stated in the article 119 of the Magna Carta, the right to the territory of these populations is exercised through the public policy of demarcation, which is understood as the process in which its territorial space is disclaimed, made by the State in participation with the peoples and communities to be demarcated, subsequently to entitle the collective ownership for these human beings groups. Fifteen years after the Constitution was approved, this process of delineation has been slow and misleading. This delay has caused that in the present, these human beings groups are being stalked by outside interests (illegal mining, development projects, irregular forces, among others who threaten their existence as distinct cultures; since the right to territory is a fundamental human right for their survival. This article is the result of a field research. In the first part, the study analyzes the Organic Law of Indigenous Peoples and Communities (LOPCI (2005 in Venezuela, with the purpose of clarifying at what stage the territorial demarcation process is paralyzed; and as a result, it describes how many communities and indigenous peoples have been demarcated and entitled from 2005 to 2014.

Histochemistry and functional organization of the dorsal skin of Ancistrus dolichopterus (Siluriformes: Loricariidae

Directory of Open Access Journals (Sweden)

Tarun K. Garg

Full Text Available The structural organization and histo-cytochemical features of dorsal skin of Ancistrus dolichopterus (acari bodo are the main focus of this work. The epidermis, dermis and subcutis are the principal layers of the skin. The epidermis mainly consists of epithelial and mucous cells. Interspersed between them are lymphocytes, pigment cells, eosinophilic granular cells (EGC, and the taste buds as sensory structures. The high number of EGCs is implicated in general and specific immunological defense from pathogenic bacteria and multicellular parasites. The epithelial cells and mucous cells contain glycoproteins with oxidizable vicinal diols, carboxyl groups and O-sulphate esters and their high secretory activity is correlated with the bottom dwelling habit of this species. A thick stratum laxum contains overlapping osteoderms bearing denticles, and the stratum compactum make the integument thicker to help the fish in negative buoyancy for maneuvering near the bottom and protection. The entire body surface is covered by conical, backwardly directed denticles. These are composed of a dentine cone, surrounding a pulp cavity with the top covered by mineralized cap, and are the true homologues of teeth. These structures provide effective protection from abrasion and enemies. These structural peculiarities and histochemical features indicate additional physiological role of the skin of A. dolichopterus.

Full Text Available Objectives. To compare the outcome of dorsal buccal mucosal graft (BMG substitution urethroplasty by dorsal urethrotomy approach with ventral urethrotomy approach in management of stricture urethra. Methods and Materials. A total of 40 patients who underwent dorsal BMG substitution urethroplasty were randomized into two groups. 20 patients underwent dorsal onlay BMG urethroplasty as described by Barbagli, and the other 20 patients underwent dorsal BMG urethroplasty by ventral urethrotomy as described by Asopa. Operative time, success rate, satisfaction rate, and complications were compared between the two groups. Mean follow-up was 12 months (6–24 months. Results. Ventral urethrotomy group had considerably lesser operative time although the difference was not statistically significant. Patients in dorsal group had mean maximum flow rate of 19.6 mL/min and mean residual urine of 27 mL, whereas ventral group had a mean maximum flow rate of 18.8 and residual urine of 32 mL. Eighteen out of twenty patients voided well in each group, and postoperative imaging study in these patients showed a good lumen with no evidence of leak or extravasation. Conclusion. Though ventral sagittal urethrotomy preserves the blood supply of urethra and intraoperative time was less than dorsal urethrotomy technique, there was no statistically significant difference in final outcome using either technique.

Full Text Available The authors argue through this paper, the importance of rethinking the recently abandoned tools that can be reactivated in times of crisis. EU 2020 Strategy and other EU documents create a favorable frame in order to achieve the priorities set by reconsidering the territorial pact concept. Recent documents define the partnership agreement concept, which seems to be more rigid and less flexible than the territorial pact. Having as a starter point Romania’s specifics, there are individualized 10 thematic territorial pacts and 8 global pacts. They must generate territorial synergies capable of ensuring the coherence between regions, states and the European Union as a whole.

Systematization, distribution and territory of the caudal cerebral artery on the brain's surface of the turkey (Meleagris gallopavo

Full Text Available Thirty Meleagris gallopavo heads with their neck segments were used. Animals were contained and euthanized with the association of mebezonium iodide, embutramide and tetracaine hydrochloride (T 61, Intervet by intravenous injection. The arterial system was rinsed with cold saline solution (15°C, with 5000IU heparin and filled with red-colored latex. The samples were fixed in 20% formaldehyde for seven days. The brains were removed with a segment of cervical spinal cord and after, the dura-mater was removed and the arteries dissected. The cerebral carotid arteries, after the intercarotid anastomosis, were projected around the hypophysis, until they reached the tuber cinereum and divided into their terminal branches, the caudal branch and the rostral branch. The rostral branch was projected rostrolateralwards and gave off, in sequence, two collateral branches, the caudal cerebral and the middle cerebral arteries and the terminal branch was as cerebroethmoidal artery. The caudal cerebral artery of one antimere formed the interhemispheric artery, which gave off dorsal hemispheric branches to the convex surface of both antimeres. Its dorsal tectal mesencephalic branch, of only one antimere, originated the dorsal cerebellar artery. In the interior of the cerebral transverse fissure, after the origin of the dorsal tectal mesencephalic artery, the caudal cerebral artery emitted occipital hemispheric branches, pineal branches and medial hemispheric branches, on both antimeres. The caudal cerebral artery's territory comprehended the entire surface of the dorsal hemioptic lobe, the rostral surface of the cerebellum, the diencephalic structures, the caudal pole and the medial surface of the cerebral hemisphere and in the convex surface, the sagittal eminence except for its most rostral third. Due to the asymmetry found in the caudal cerebral arteries' ramifications, the models were classified into three types and their respective subtypes.

To compare the finite element models of two different composite radius fracture patterns, reduced and stabilised with four different fixed-angle dorsal plates during axial, dorsal and volar loading conditions. Eight different plastic models representing four AO/ASIF type 23-A3 distal radius fractures and four AO/ASIF 23-C2 distal radius fractures were obtained and fixed each with 1 of 4 methods: a standard dorsal non-anatomical fixed angle T-plate (3.5mm Dorsal T-plate, Synthes), anatomical fixed-angle double plates (2.4mm LCP Dorsal Distal Radius, Synthes), anatomical fixed angle T-plate (2.4mm Acu-Loc Dorsal Plate, Acumed) or anatomical variable-angle dorsal T-plate (3.5mm, Dorsal Plate, Zrinski). Composite radius with plate and screws were scanned with a 3D optical scanner and later processed in Abaqus Software to generate the finite element model. All models were axially loaded at 3 points (centrally, volarly and dorsally) with 50 N forces to avoid the appearance of plastic deformations of the models. Total displacements at the end of the bone and the stresses in the bones and plates were determined and compared. Maximal von Mises stress in bone for 3-part fracture models was very similar to that in 2-part fracture models. The biggest difference between models and the largest displacements were seen during volar loading. The stresses in all models were the highest above the fracture gap. The best performance in all parameters tested was with the Zrinski plate and the most modest results were with the Synthes T-plate. There was no significant difference between 2-part (AO/ASIF type 23-A3) and 3-part (AO/ASIF 23-C2) fracture models. Maximal stresses in the plates appeared above the fracture gap; therefore, it is worth considering the development of plates without screw holes above the gap. © 2017 Elsevier Ltd.

Personal authentication through dorsal hand vein patterns

Hsu, Chih-Bin; Hao, Shu-Sheng; Lee, Jen-Chun

2011-08-01

Biometric identification is an emerging technology that can solve security problems in our networked society. A reliable and robust personal verification approach using dorsal hand vein patterns is proposed in this paper. The characteristic of the approach needs less computational and memory requirements and has a higher recognition accuracy. In our work, the near-infrared charge-coupled device (CCD) camera is adopted as an input device for capturing dorsal hand vein images, it has the advantages of the low-cost and noncontact imaging. In the proposed approach, two finger-peaks are automatically selected as the datum points to define the region of interest (ROI) in the dorsal hand vein images. The modified two-directional two-dimensional principal component analysis, which performs an alternate two-dimensional PCA (2DPCA) in the column direction of images in the 2DPCA subspace, is proposed to exploit the correlation of vein features inside the ROI between images. The major advantage of the proposed method is that it requires fewer coefficients for efficient dorsal hand vein image representation and recognition. The experimental results on our large dorsal hand vein database show that the presented schema achieves promising performance (false reject rate: 0.97% and false acceptance rate: 0.05%) and is feasible for dorsal hand vein recognition.

Neuroradiological evaluation of dorsal cyst malformations

Utsunomiya, Hidetsuna; Hayashi, Takashi; Hashimoto, Takeo; Matsuishi, Toyojiro; Okudera, Toshio.

1988-01-01

We discussed six cases with dorsal cyst malformations listing their neuroradiological observations and proposed to differentiate between the holosphere and hemisphere as defined by Yokota (1984). The cases were divided into holospheric and hemispheric groups depending on the continuity of their frontal lobe midlines. Cases 1, 2 and 3 were placed in the holospheric group because of their unseparated frontal lobe sbeneath the partially formed anterior interhemispheric fissures. Cases 4, 5 and 6 were grouped in the hemisphere due to the completion of the interhemispheric fissures. There has been a tendency in recent years for most cases of cerebral malformations having an endogenous dorsal cyst with monoventricular configuration to be diagnosed as holoprosencephaly. However, we believe that only patients who have a dorsal cyst in the holospheric brain should be included, and the others in the hemispheric brain, which is capable of completing hemispheric cleavage, should not. Therefore, we emphasize the importance of correctly identifying the holospheric state in the dorsal cyst malformations for diagnosing holoprosencephaly. (author)

The territorial approach to EU cohesion policy: Current issues and evidence from Greece

2011-01-01

Full Text Available The importance attributed to the territorial dimension of the European Union cohesion policy steadily influences its successive reforms and adaptations, while in recent years there has been an evolution in the way this particular dimension of cohesion policy is perceived. Important evidence for this is the way in which the Community Strategic Guidelines on cohesion 2007-13 take account of the territorial dimension of cohesion policy. This paper discusses the territorial approach to cohesion policy in relation to both policy and practice. Specifically, it examines the territorial dimension of regional development planning in Greece as it has emerged in the relevant official documents, namely the successive three Community Support Frameworks since 1989 and the National Strategic Reference Framework for the current 2007-13 period. The territorial dimension of the organization of the planning system is also considered in an effort to understand limitations and prospects, in light of the importance of the territorial approach to cohesion policy post-2013.

"Territorial promiscuity” and border demarcation in Piedmont. The case of Piovà Massaia and Cerreto d’Asti

Directory of Open Access Journals (Sweden)

Renato Bordone

2006-06-01

Full Text Available The relationship between a community organized in an established administrative structure and the surrounding territory and its exploitable resources is not always definitely biunique. We will discuss some cases in Piedmont, illustrating the persistence of situations dating back to the Middle Ages that still affect the administrative structures. Particular attention will be given to the boundary dispute between Cerreto d’Asti and Piovà Massaia, originating from a long-lasting condition of uncertain boundaries between the two territories. Originally, both villages were part of one ecclesiastical-political district (the Mairate parish church, with no territorial divisions. In the Modern Age each of them achieved a more defined territorial status; yet, there remained (and still remain areas of uncertain attribution. The dispute that is now in progress is the heritage of a territorial organization dating back to the Middle Ages, at present opposing a different, universally adopted model. Thus two alternatives – originally not in contrast – emerge: either sharing the territorial resources or exploiting them in an exclusive way.

2013-01-01

Since skin of the dorsal hands is a known site for the development of cutaneous squamous cell carcinoma, an epidemiologic investigation was needed to determine if beachgoers apply sunscreen to the dorsal aspect of their hands as frequently as they apply it to other skin sites. Aim. The aim of the current study was to compare the use of sunscreen on the dorsal hands to other areas of the body during subtropical late spring and summer sunlight exposure at the beach. Materials and Methods. A cross-sectional survey from a convenience sample of beachgoers was designed to evaluate responded understanding and protective measures concerning skin cancer on the dorsal hands in an environment with high natural UVR exposure. Results. A total of 214 surveys were completed and analyzed. Less than half of subjects (105, 49%) applied sunscreen to their dorsal hands. Women applied sunscreen to the dorsal hands more than men (55% women versus 40% men, ρ=0.04 ). Higher Fitzpatrick Skin Type respondents were less likely to protect their dorsal hands from ultraviolet radiation (ρ=0.001 ). Conclusions. More public education focused on dorsal hand protection from ultraviolet radiation damage is necessary to reduce the risk for squamous cell carcinomas of the hands.

De-Territorialization and Re-Territorialization of “the social”. A debate

Directory of Open Access Journals (Sweden)

2008-07-01

Full Text Available Deterritorialization has been used as an anthropological concept to designate the weakened ties between culture and place: Certain cultural/social processes and relations seem to increasingly transcend their previously given territorial boundaries in flexible capitalist societies. At the same time, policy studies, especially Studies on Governmentality, have emphasized the re-territorialization of the social, in which the former national welfare arrangements (welfare and nation state as the scale of bio-political integration patterns are more and more substituted by small scaled inclusion areas (e.g. neighbourhoods, districts and communities. Drawing on Deleuze and Guattari, de-territorialization processes have therefore always to be understood as combined with processes of a re-territorialization, producing new spatial formations. In this view, spatial arrangements and connections are not given and static structures, but controversial and unstable – nevertheless they are influential.

Organization of Functional Long-Range Circuits Controlling the Activity of Serotonergic Neurons in the Dorsal Raphe Nucleus

Directory of Open Access Journals (Sweden)

Li Zhou

2017-03-01

Full Text Available Serotonergic neurons play key roles in various biological processes. However, circuit mechanisms underlying tight control of serotonergic neurons remain largely unknown. Here, we systematically investigated the organization of long-range synaptic inputs to serotonergic neurons and GABAergic neurons in the dorsal raphe nucleus (DRN of mice with a combination of viral tracing, slice electrophysiological, and optogenetic techniques. We found that DRN serotonergic neurons and GABAergic neurons receive largely comparable synaptic inputs from six major upstream brain areas. Upon further analysis of the fine functional circuit structures, we found both bilateral and ipsilateral patterns of topographic connectivity in the DRN for the axons from different inputs. Moreover, the upstream brain areas were found to bidirectionally control the activity of DRN serotonergic neurons by recruiting feedforward inhibition or via a push-pull mechanism. Our study provides a framework for further deciphering the functional roles of long-range circuits controlling the activity of serotonergic neurons in the DRN.

2013-01-01

We report the discovery of light organs (photophores) adjacent to the dorsal defensive spines of a small deep-sea lanternshark (Etmopterus spinax). Using a visual modeling based on in vivo luminescence recordings we show that this unusual light display would be detectable by the shark's potential predators from several meters away. We also demonstrate that the luminescence from the spine-associated photophores (SAPs) can be seen through the mineralized spines, which are partially translucent. These results suggest that the SAPs function, either by mimicking the spines' shape or by shining through them, as a unique visual deterrent for predators. This conspicuous dorsal warning display is a surprising complement to the ventral luminous camouflage (counterillumination) of the shark.

Full Text Available In this study we analyzed the microanatomy of the dorsal vessel of the triatomine Panstrongylus megistus. The organ is a tuble anatomically divided into an anterior aorta anad a posterior heart, connected to the body wall through 8 pairs of alary muscles. The heart is divided in 3 chambers by means of 2 pairs of cardiac valves. a pair of ostia can be observed in the lateral wall of each chamber. A bundle of nerve fibers was found outside the organ, running dorsally along its major axis. A group of longitudinal muscular fibers was found in the ventral portion of the vessel. The vessel was found to be lined both internally and externally by pericardial cells covered by a thin laminar membrane. Inseide the vessel the pericardial cells were disposed in layers and on the outside they formed clusters or rows.

2009-01-01

During the last 100 years in medical literature, there are only 54 reports, including the report of Pasaoglu et al (World J Gastroenterol 2008; 14: 2915-2916), with clinical descriptions of agenesis of the dorsal pancreas in humans. Agenesis of the dorsal pancreas, a rare congenital pancreatic malformation, is associated with some other medical conditions such as hyperglycemia, abdominal pain, pancreatitis and a few other diseases. In approximately 50% of reported patients with this congenital malformation, hyperglycemia was demonstrated. Evaluation of hyperglycemia and diabetes mellitus in all patients with agenesis of the dorsal pancreas including description of fasting blood glucose, oral glucose tolerance test, glycated hemoglobin and medical treatment would be a future goal. Since autosomal dominant transmission has been suggested in single families, more family studies including imaging technologies with demonstration of the pancreatic duct system are needed for evaluation of this disease. With this letter to the editor, we aim to increase available information for the better understanding of this rare disease. PMID:19140241

Emergent properties during dorsal closure in Drosophila morphogenesis

Peralta, X G; Toyama, Y; Edwards, G S; Kiehart, D P

2008-01-01

Dorsal closure is an essential stage of Drosophila development that is a model system for research in morphogenesis and biological physics. Dorsal closure involves an orchestrated interplay between gene expression and cell activities that produce shape changes, exert forces and mediate tissue dynamics. We investigate the dynamics of dorsal closure based on confocal microscopic measurements of cell shortening in living embryos. During the mid-stages of dorsal closure we find that there are fluctuations in the width of the leading edge cells but the time-averaged analysis of measurements indicate that there is essentially no net shortening of cells in the bulk of the leading edge, that contraction predominantly occurs at the canthi as part of the process for zipping together the two leading edges of epidermis and that the rate constant for zipping correlates with the rate of movement of the leading edges. We characterize emergent properties that regulate dorsal closure, i.e., a velocity governor and the coordination and synchronization of tissue dynamics

In the present study, we investigated the role of endogenous neurotrophin-3 in nerve terminal sprouting 2 months after spinal cord dorsal root rhizotomy. The left L1-5 and L7-S2 dorsal root ganglia in adult cats were exposed and removed, preserving the L6 dorsal root ganglia. Neurotrophin-3 was mainly expressed in large neurons in the dorsal root ganglia and in some neurons in spinal lamina II. Two months after rhizotomy, the number of neurotrophin-3-positive neurons in the spared dorsal root ganglia and the density of neurite sprouts emerging from these ganglia were increased. Intraperitoneal injection of an antibody against neurotrophin-3 decreased the density of neurite sprouts. These findings suggest that endogenous neurotrophin-3 is involved in spinal cord plasticity and regeneration, and that it promotes axonal sprouting from the dorsal root ganglia after spinal cord dorsal root rhizotomy.

The city, territoriality and networks in mental health policies

Directory of Open Access Journals (Sweden)

Luciana Assis Costa

2014-09-01

Full Text Available The understanding of territory, made evident by a decentralized, local based, and non-institutionalized mental health model, is a fundamental element in building a renewed network. The objective of this essay is to understand how mental health policies gradually favor local actions, organized in terms of territories, to develop strategies of care that support the new model of mental health. From this perspective, the aim of this research is to reflect on the possibilities of establishing new social relations that can, in fact, widen the sense of community belonging in the daily living of those presenting mental health conditions. This study draws from theoretical concepts and frameworks of the social sciences, describing the diverse positions held by the main schools of urban sociology with regards to the understanding of territories. The multiple conceptions of territories and their relations to mental health are analyzed. Historical data about mental health in Brazil show a heterogeneous development of mental health policies in different areas of the country. Finally, social inclusion in the cities depends on an effective expansion of territory-based mental health services, as well as an amplification of the access to consumer goods and services not necessarily connected to health care, but to basic social and civil rights. Hopefully, new rules of social interaction will not be restricted to the mental health universe, but will promote new encounters in the urban space, with respect for differences and appreciation of diversity.

The article describes by means of a methodological process and inside an analysis mark that picks up aspects tried from the perspective of agrarian economy and the human geography, the effects of the public politics of the rural reservations in Bolivar's south, as well as its advances and challenges in the territorial reorganization of the territory. In this context, the document evidences the process of the new territorial configurations, in Bolivar's south, result of a social construction exercised by its own rural communities. In a same way the document presents a brief analysis of the agrarian structure of the rural reservations, and it illustrates the new underlying classification, product of the territorial control that develop the illegal armed groups at the moment. The advances, difficulties and challenges of the rural reservations, are the central axis of the present text, since the figure is presents as an interesting project of public politics, not alone of colonization and of agrarian reformation, but of territorial rural ordination, stiller, when in the country it has not been possible to approve an organic law of territorial classification that involves in an integral way the territorial aspects with the agrarian ones, going outside of the conception of the agrarian things of the strictly agricultural thing

2016-09-01

Full Text Available The Citizenship Territories Program, created in 2008 to replace the Rural Areas Program 2003, stands out as the Brazilian territorial development policy. This work aims, from the analysis of the Central Territory Citizenship of Rio Grande do Sul, to identify if the limits and possibilities of implementation of this territory are from public policy or from particularities of the region itself. Were outlined four keys for analytical analysis, which seek to discuss how policy has been implemented and how the notion of territorial development has been appropriated by society. In addition, we seek to present the main limitations for the development of territorial politics. Even if the territory proves an important forum for discussion and mobilization in the region, yet is insufficient to account for the territorial development, since the actions and policies of development for the circumscribed space not fully converge.

Full Text Available The current exigencies that a territory must faced in order to its’ optimalpositioning in future regional competition requires the ability to design theappropriate mechanism which better valorize the territory capability. Such aconstruct is vital for territorial sustainable development and supposes thecreation of a specific body of knowledge from distinctive local resourceexploitation and unique value creation and allocation. Territorial mechanismdesign is a typical management decision about identification, ownership andcontrol of specific strategic capabilities and their combination in a distinctiveterritorial portfolio. The most difficult responsibility is to allocate the territorialvalue added which is a source of conflict among territorial components. Ourcurrent paper research covers the basics of two complementary territorialpillars-rural and tourism potential and proves the lack of specific designmechanisms which explain the current diminishing value of Galati Brailaregion. The proposed management system, relying upon territorial controlmechanism, will ensure knowledge sharing process via collaborative learning,with the final role of appropriate territorial attractivity signals, reinforcingidentity as key factor of territorial attractability. Our paper is fully documentedon there years of data analyzing from territorial area of interest. This offers usthe necessary empiric contrasting for our proposed solution.

Couch potatoes do better: Delayed dispersal and territory size affect the duration of territory occupancy in a monogamous mammal.

Mayer, Martin; Zedrosser, Andreas; Rosell, Frank

2017-06-01

In territorial, socially monogamous species, the establishment and defense of a territory are an important strategy to maximize individual fitness, but the factors responsible for the duration of territory occupancy are rarely studied, especially in long-lived mammals. A long-term monitoring program in southeast Norway spanning over 18 years allowed us to follow the individual life histories of Eurasian beavers ( Castor fiber ) from adolescence in their natal family group to dispersal and territory establishment until the end of territory occupancy. We investigated whether territory size, resource availability, population density, and dispersal age could explain the duration of territory occupancy, which ranged from 1 to 11 years. The duration of territory occupancy was positively related to dispersal age, suggesting that individuals that delayed dispersal had a competitive advantage due to a larger body mass. This is in support with the maturation hypothesis, which states that an animal should await its physical and behavioral maturation before the acquisition of a territory. Further, we found that individuals that established in medium-sized territories occupied them longer as compared to individuals in small or large territories. This suggests that large territories are more costly to defend due to an increased patrolling effort, and small territories might not have sufficient resources. The lifetime reproductive success ranged from zero to six kits and generally increased with an increasing duration of territory occupancy. Our findings show the importance of holding a territory and demonstrate that dispersal decisions and territory selection have important consequences for the fitness of an individual.

Propuesta de un Modelo de Inteligencia Territorial

Directory of Open Access Journals (Sweden)

Ana Rosa Guzmán

2013-04-01

Full Text Available A territory is built on the shared space and interaction between diverse public and private actors providing knowledge and resources that encourage development of the territory according to their own trajectories, visions and contexts. Territorial development depends on the competences and efforts of these actors to articulate territorial networks and to build knowledge assets around the territorial possibilities and potential, so they can act favorably in front of the changing environment, deploying both adaptive and predictive behavior. This paper proposes a conceptual model of territorial intelligence that includes the processes that allow territorial appropriation of knowledge as well as the development of a collective intelligence to promote the sustainable development of the territory.

Neural correlates of consciousness: a definition of the dorsal and ventral streams and their relation to phenomenology.

Science.gov (United States)

Vakalopoulos, Costa

2005-01-01

The paper presents a hypothesis for a neural correlate of consciousness. A proposal is made that both the dorsal and ventral streams must be concurrently active to generate conscious awareness and that V1 (striate cortex) provides a serial link between them. An argument is presented against a true extrastriate communication between the dorsal and ventral streams. Secondly, a detailed theory is developed for the structure of the visual hierarchy. Premotor theory states that each organism-object interaction can be described by the two quantitative measures of torque and change in joint position served by the basal ganglia and cerebellum, respectively. This leads to a component theory of motor efference copy providing a fundamental tool for categorizing dorsal and ventral stream networks. The rationale for this is that the dorsal stream specifies spatial coordinates of the external world, which can be coded by the reafference of changes in joint position. The ventral stream is concerned with object recognition and is coded for by forces exerted on the world during a developmental exploratory phase of the organism. The proposed pathways for a component motor efference copy from both the cerebellum and basal ganglia converge on the thalamus and modulate thalamocortical projections via the thalamic reticular nucleus. The origin of the corticopontine projections, which are a massive pathway for cortical information to reach the cerebellum, coincides with the area typically considered as part of the dorsal stream, whereas the entire cortex projects to the striatum. This adds empirical support for a new conceptualization of the visual streams. The model also presents a solution to the binding problem of a neural correlate of consciousness, that is, how a distributed neural network synchronizes its activity during a cognitive event. It represents a reinterpretation of the current status of the visual hierarchy.

Serotonergic neurons play key roles in various biological processes. However, circuit mechanisms underlying tight control of serotonergic neurons remain largely unknown. Here, we systematically investigated the organization of long-range synaptic inputs to serotonergic neurons and GABAergic neurons in the dorsal raphe nucleus (DRN) of mice with a combination of viral tracing, slice electrophysiological, and optogenetic techniques. We found that DRN serotonergic neurons and GABAergic neurons receive largely comparable synaptic inputs from six major upstream brain areas. Upon further analysis of the fine functional circuit structures, we found both bilateral and ipsilateral patterns of topographic connectivity in the DRN for the axons from different inputs. Moreover, the upstream brain areas were found to bidirectionally control the activity of DRN serotonergic neurons by recruiting feedforward inhibition or via a push-pull mechanism. Our study provides a framework for further deciphering the functional roles of long-range circuits controlling the activity of serotonergic neurons in the DRN. Copyright © 2017 The Author(s).

Full Text Available The aim of this research is to analyze territorial capital as a new paradigm to make best use of endogenous assets. The study is dealing with the preconditions, meaning and possible theoretical taxonomies of territorial capital. In this study I emphasize that the cumulative effects of regional potentials are more important than economies of scale and location factors. I present different approaches and interpretations of territorial capital, then make an attempt to create an own model. I try to find answers for questions, such as why territorial capital shows a new perspective of urban and regional development; how cognitive elements of territorial capital provide increasing return; how territorial capital influences competitiveness and what kind of relation it has with cohesion.

Drosophila heart cell movement to the midline occurs through both cell autonomous migration and dorsal closure.

Science.gov (United States)

Haack, Timm; Schneider, Matthias; Schwendele, Bernd; Renault, Andrew D

2014-12-15

The Drosophila heart is a linear organ formed by the movement of bilaterally specified progenitor cells to the midline and adherence of contralateral heart cells. This movement occurs through the attachment of heart cells to the overlying ectoderm which is undergoing dorsal closure. Therefore heart cells are thought to move to the midline passively. Through live imaging experiments and analysis of mutants that affect the speed of dorsal closure we show that heart cells in Drosophila are autonomously migratory and part of their movement to the midline is independent of the ectoderm. This means that heart formation in flies is more similar to that in vertebrates than previously thought. We also show that defects in dorsal closure can result in failure of the amnioserosa to properly degenerate, which can physically hinder joining of contralateral heart cells leading to a broken heart phenotype.

Individual quality explains variation in reproductive success better than territory quality in a long-lived territorial raptor.

Directory of Open Access Journals (Sweden)

Jabi Zabala

Full Text Available Evolution by natural selection depends on the relationship between individual traits and fitness. Variation in individual fitness can result from habitat (territory quality and individual variation. Individual quality and specialization can have a deep impact on fitness, yet in most studies on territorial species the quality of territory and individuals are confused. We aimed to determine if variation in breeding success is better explained by territories, individual quality or a combination of both. We analysed the number of fledglings and the breeding quality index (the difference between the number of fledglings of an individual/breeding pair and the average number of fledglings of the monitored territories in the same year as part of a long term (16 years peregrine falcon (Falco peregrinus monitoring program with identification of individuals. Using individual and territory identities as correlates of quality, we built Generalised Linear Models with Mixed effects, in which random factors depicted different hypotheses for sources of variation (territory/individual quality in the reproductive success of unique breeding pairs, males and females, and assessed their performance. Most evidence supported the hypothesis that variation in breeding success is explained by individual identity, particularly male identity, rather than territory. There is also some evidence for inter year variations in the breeding success of females and a territory effect in the case of males. We argue that, in territorial species, individual quality is a major source of variation in breeding success, often masked by territory. Future ecological and conservation studies on habitat use should consider and include the effect of individuals, in order to avoid misleading results.

Versatile and simple approach to determine astrocyte territories in mouse neocortex and hippocampus.

Directory of Open Access Journals (Sweden)

Antje Grosche

Full Text Available BACKGROUND: Besides their neuronal support functions, astrocytes are active partners in neuronal information processing. The typical territorial structure of astrocytes (the volume of neuropil occupied by a single astrocyte is pivotal for many aspects of glia-neuron interactions. METHODS: Individual astrocyte territorial volumes are measured by Golgi impregnation, and astrocyte densities are determined by S100β immunolabeling. These data are compared with results from conventionally applied methods such as dye filling and determination of the density of astrocyte networks by biocytin loading. Finally, we implemented our new approach to investigate age-related changes in astrocyte territories in the cortex and hippocampus of 5- and 21-month-old mice. RESULTS: The data obtained by our simplified approach based on Golgi impregnation were compared to previously published dye filling experiments, and yielded remarkably comparable results regarding astrocyte territorial volumes. Moreover, we found that almost all coupled astrocytes (as indicated by biocytin loading were immunopositive for S100β. A first application of this new experimental approach gives insight in age-dependent changes in astrocyte territorial volumes. They increased with age, while cell densities remained stable. In 5-month-old mice, the overlap factor was close to 1, revealing little or no interdigitation of astrocyte territories. However, in 21-month-old mice, the overlap factor was more than 2, suggesting that processes of adjacent astrocytes interdigitate. CONCLUSION: Here we verified the usability of a simple, versatile method for assessing astrocyte territories and the overlap factor between adjacent territories. Second, we found that there is an age-related increase in territorial volumes of astrocytes that leads to loss of the strict organization in non-overlapping territories. Future studies should elucidate the physiological relevance of this adaptive reaction of

URBAN REGIONAL NETWORKS AND TERRITORIAL DEVELOPMENT: AN ANALYSIS OF “MINAS GERAIS” NORTHWEST TERRITORY IN RECENT YEARS

Clesio Marcelino Jesus

2016-09-01

Full Text Available This article aims to show that the establishment of a rural area as a cutout for implementation of public policies for development needs to consider the configuration of the urban network of the municipalities that compose it, identifying what are the hierarchical relationships between the municipalities that make up the territory and if the most dynamic centers radiate influence to the whole. We present the case study of the Northwest Territory of Minas, where were identified various limits for the implementation of territorial development policies. In this article it is shown that such limits are manifested largely because the territory groups municipalities that have different polarizations and establish differentiated functional relationships within the regional urban network. It was found that in this territorial clipping are articulated different social production systems and that the delimitation of the territory does not match even with the regionalization of state and federal agencies.

Pla, Patrick; Monsoro-Burq, Anne H

2018-05-28

The neural crest is induced at the edge between the neural plate and the nonneural ectoderm, in an area called the neural (plate) border, during gastrulation and neurulation. In recent years, many studies have explored how this domain is patterned, and how the neural crest is induced within this territory, that also participates to the prospective dorsal neural tube, the dorsalmost nonneural ectoderm, as well as placode derivatives in the anterior area. This review highlights the tissue interactions, the cell-cell signaling and the molecular mechanisms involved in this dynamic spatiotemporal patterning, resulting in the induction of the premigratory neural crest. Collectively, these studies allow building a complex neural border and early neural crest gene regulatory network, mostly composed by transcriptional regulations but also, more recently, including novel signaling interactions.

Full Text Available The end of World War I and the victory of the forces of Antante on 11 November 1918 did not result in the end of war in Londonized Albania and in the territories inhabited by Albanian people in Yugoslavia and Greece because neighbouring countries did not withdraw from Albanian territories since their desires were to extend even more to the detriment of the Albanian and were not satisfi ed only with the invasion of Kosovo by Serbia, Cameria by Greece, and Italy aspiring to keep Albania under its supervision. The European countries of Antante, such as England, France and Italy, did not support the Albanian people because they had reached an agreement during the World War 1 to conquer the countries of the triple alliance by promising Albanian territories to the neighbouring countries of Albania. The Protocol of April 1915 was devastating for Albania. The fate of Albanian people was such that European countries could not change the course of the World War 1. The intervention of USA was the one that changed the course of the World War 1, and USA even joined the war by stating that it did not recognize the agreements made during the war with regard to the territorial division. The neighboring countries of Albania had forgo$ en that in the global stage a political-military power was emerging which would lay the foundations of the new world order. Even though the war had ended, the neighboring countries of Albania were making agreements for the supervision of Albania. Italy was interested in keeping Albania under its supervision whereas Greece and Yugoslavia were interested in the division of Albania. Under these circumstances the Albanian people was facing new invasive challenges and they had to get organized both inside and outside the country for their national salvation. Albanians were organized in clubs and associations abroad, in order to help the freedom of Londonized Albania. The Albanians in Albania were fed up with long and savage invasions

Full Text Available The dorsal striatum (caudate/putamen is a node of the cortico-striato-pallido-thalamo-cortical (CSPTC motor circuit, which plays a central role in skilled motor learning, a critical feature of musical performance. The dorsal striatum receives input from a large part of the cerebral cortex, forming a hub in the cortical-subcortical network. This study sought to examine how the functional network of the dorsal striatum differs between musicians and nonmusicians.Resting state functional magnetic resonance imaging (fMRI data were acquired from female university students majoring in music and nonmusic disciplines. The data were subjected to graph theoretical analysis and functional connectivity analysis. The graph theoretical analysis of the entire brain revealed that the degree, which represents the number of connections, of the bilateral putamen was significantly lower in musicians than in nonmusicians. The functional connectivity analysis indicated that compared with nonmusicians, musicians had significantly decreased connectivity between the left putamen and bilateral frontal operculum and between the left caudate nucleus and cerebellum. In conclusion, compared with nonmusicians, female musicians have a smaller functional network of the dorsal striatum, with decreased connectivity. These data are consistent with previous anatomical studies reporting a reduced volume of the dorsal striatum in musicians and ballet dancers. To the best of our knowledge, this is the first study suggesting that long-term musical training results in a less extensive or selective functional network of the dorsal striatum.

Recent trends in environmental assessment theory and practice indicate a growing concern with collaboration and learning. Although there are few examples of the institutional, organizational, and socio-political forms and processes required to foster this collaboration and learning, the establishment of an environmental planning, management, and assessment regime in Canada's Northwest Territories offers useful insights. Consequently, this paper identifies and examines the institutional, organizational, and socio-political conditions that have encouraged more collaborative forms of environmental assessment practice in the Northwest Territories. Key issues highlighted include: (1) the development of decentralized regulatory organizations more responsive to changing circumstances; (2) strategies for more effective communication and participation of community interests; (3) efforts to build a collaborative vision of economic and social development through region-specific land use plans; (4) the integration of knowledge frameworks; and (5) a concern with the capacity required to encourage effective intervention in the assessment process

Patterning Muscles Using Organizers: Larval Muscle Templates and Adult Myoblasts Actively Interact to Pattern the Dorsal Longitudinal Flight Muscles of Drosophila

Pattern formation in muscle development is often mediated by special cells called muscle organizers. During metamorphosis in Drosophila, a set of larval muscles function as organizers and provide scaffolding for the development of the dorsal longitudinal flight muscles. These organizers undergo defined morphological changes and dramatically split into templates as adult fibers differentiate during pupation. We have investigated the cellular mechanisms involved in the use of larval fibers as templates. Using molecular markers that label myoblasts and the larval muscles themselves, we show that splitting of the larval muscles is concomitant with invasion by imaginal myoblasts and the onset of differentiation. We show that the Erect wing protein, an early marker of muscle differentiation, is not only expressed in myoblasts just before and after fusion, but also in remnant larval nuclei during muscle differentiation. We also show that interaction between imaginal myoblasts and larval muscles is necessary for transformation of the larval fibers. In the absence of imaginal myoblasts, the earliest steps in metamorphosis, such as the escape of larval muscles from histolysis and changes in their innervation, are normal. However, subsequent events, such as the splitting of these muscles, fail to progress. Finally, we show that in a mutant combination, null for Erect wing function in the mesoderm, the splitting of the larval muscles is aborted. These studies provide a genetic and molecular handle for the understanding of mechanisms underlying the use of muscle organizers in muscle patterning. Since the use of such organizers is a common theme in myogenesis in several organisms, it is likely that many of the processes that we describe are conserved. PMID:9606206

Full Text Available This article deals with the development of monoculture index (MI of eucalyptus as a key element for the management of the territory, from the perspective of sustainable development. We analyzed the "geography" of the eucalyptus plantation in Minas Gerais, to support the planning, organization, control and use of territory. The Monoculture index proposed, which is an important tool for land management, was developed and validate by its application to municipalities of Minas Gerais state. It was shown that the culture of Eucalyptus represents a low rate of monoculture in the state of Minas Gerais and that the geography of this culture is compatible with sustainable territorial expansion. Therefore, these results contribute to the definition of public land management in Minas Gerais and the methodology used can be applied to other states.

An influential striatal model postulates that neural activities in the striatal direct and indirect pathways promote and inhibit movement, respectively. Normal behavior requires coordinated activity in the direct pathway to facilitate intended locomotion and indirect pathway to inhibit unwanted locomotion. In this striatal model, neuronal population activity is assumed to encode locomotion relevant information. Here, we propose a novel encoding mechanism for the dorsal striatum. We identified spatially compact neural clusters in both the direct and indirect pathways. Detailed characterization revealed similar cluster organization between the direct and indirect pathways, and cluster activities from both pathways were correlated with mouse locomotion velocities. Using machine-learning algorithms, cluster activities could be used to decode locomotion relevant behavioral states and locomotion velocity. We propose that neural clusters in the dorsal striatum encode locomotion relevant information and that coordinated activities of direct and indirect pathway neural clusters are required for normal striatal controlled behavior.

The objectives of this research were to further delineate the neural circuits subserving proposed memory-based behavioural subsystems in the hippocampal formation. These studies were guided by anatomical evidence showing a topographical organization of the hippocampal formation. Briefly, perpendicular to the medial/lateral entorhinal cortex division there is a second system of parallel circuits that separates the dorsal and ventral hippocampus. Recent work from this laboratory has provided evidence that the hippocampus incidentally encodes a context-specific inhibitory association during acquisition of a visual discrimination task. One question that emerges from this dataset is whether the dorsal or ventral hippocampus makes a unique contribution to this newly described function. Rats with neurotoxic lesions of the dorsal or ventral hippocampus were assessed on the acquisition of the visual discrimination task. Following asymptotic performance they were given reversal training in either the same or a different context from the original training. The results showed that the context-specific inhibition effect is mediated by a circuit that includes the ventral but not the dorsal hippocampus. Results from a control procedure showed that rats with either dorso-lateral striatum damage or dorsal hippocampal lesions were impaired on a tactile/spatial discrimination. Taken together, the results represent a double dissociation of learning and memory function between the ventral and dorsal hippocampus. The formation of an incidental inhibitory association was dependent on ventral but not dorsal hippocampal circuitry, and the opposite dependence was found for the spatial component of a tactile/spatial discrimination.

2017-07-01

Full Text Available This paper analyzes, based on data from 2010, the social organization in Brazil, measured by the distribution of Private Foundations and Non-Profit Associations (FASFIL, comparing them with the main socioeconomic indicators. The concept of socio-territorial capital is adopted, based on the notion of social capital (PUTNAM, 1996. This concept values the territorial networking, the bonds of cohesion and cooperation and the territorial rooting, that is, the interaction in different sectors and scales. An analysis is made for the relation between by FASFIL and GDP per capita for the Major Regions and for the Federation Units. The results confirm regional imbalances and interstate imbalances, that is, where there is more FASFIL income is higher. The analysis is also done for the main metropolitan regions and for the metropolises, now involving, in addition to GDP per capita, seven socioeconomic indicators (HDI, Gini index, Life expectancy at birth, Infant mortality, Persons with complete upper level, Percentage of vulnerable to poverty and Formalization of the employed. The results are more expressive than in the scale of the Federation Units, especially at the level of the metropolises, that is, they express more prominently the relation between FASFIL and socio territorial capital.

Vieira, Claudia; Pombero, Ana; García-Lopez, Raquel; Gimeno, Lourdes; Echevarria, Diego; Martínez, Salvador

2010-01-01

The vertebrate Central Nervous System (CNS) originates from the embryonic dorsal ectoderm. Differentiation of the neural epithelium from the ectoderm and the formation of the neural plate constitute the first phase of a complex process called neurulation which culminates in the formation of the neural tube, the anlage of the CNS in sauropsids and mammals (for review see Smith and Schoenwolf, 1997; Colas and Schoenwolf, 2001). At neural plate and neural tube stages, local signaling centers in the neuroepithelium, known as secondary organizers, refine the antero-posterior specification of different neural territories (for review see Echevarria et al., 2003; Stern et al.,2006; Woltering and Durston, 2008). In this review, we will describe the principle aspects of CNS development in birds and mammals, starting from early stages of embryogenesis (gastrulation and neurulation) and culminating with the formation of a variety of different regions which contribute to the structural complexity of the brain (regionalization and morphogenesis). We will pay special attention to the cellular and molecular mechanisms involved in neural tube regionalization and the key role played by localized secondary organizers in the patterning of neural primordia.

Highland rural constellations. Territory occupation logics and models of order at the North of Traslasierra [Córdoba, Argentina

Directory of Open Access Journals (Sweden)

Fernando Diaz Terreno

2013-07-01

Full Text Available A set of intentioned readings made on an ancient Córdoba’s landscape reveal the occupation logics developed over centuries of territorial construction. These logics result from the combination of cultural ways of domination and exploitation of space, technical resources available and the natural landscape conditions imposed. From these processes, models of territorial order emerge as operational synthesis from the accumulation of human labor in the territory, gathering –in their own material structure– the key for future planning criteria. Just like constellation structures, order models express a form of spatial organization and some type of rurality specific from Northern Traslasierra. The aim is to arrive at a deep understanding of this postponed territory, show its cultural and natural resources and, through those, build a territorial narrative that places them back on the map of Córdoba’s regions.

Hydrodynamic function of dorsal fins in spiny dogfish and bamboo sharks during steady swimming.

Maia, Anabela; Lauder, George V; Wilga, Cheryl D

2017-11-01

A key feature of fish functional design is the presence of multiple fins that allow thrust vectoring and redirection of fluid momentum to contribute to both steady swimming and maneuvering. A number of previous studies have analyzed the function of dorsal fins in teleost fishes in this context, but the hydrodynamic function of dorsal fins in freely swimming sharks has not been analyzed, despite the potential for differential functional roles between the anterior and posterior dorsal fins. Previous anatomical research has suggested a primarily stabilizing role for shark dorsal fins. We evaluated the generality of this hypothesis by using time-resolved particle image velocimetry to record water flow patterns in the wake of both the anterior and posterior dorsal fins in two species of freely swimming sharks: bamboo sharks ( Chiloscyllium plagiosum ) and spiny dogfish ( Squalus acanthias ). Cross-correlation analysis of consecutive images was used to calculate stroke-averaged mean longitudinal and lateral velocity components, and vorticity. In spiny dogfish, we observed a velocity deficit in the wake of the first dorsal fin and flow acceleration behind the second dorsal fin, indicating that the first dorsal fin experiences net drag while the second dorsal fin can aid in propulsion. In contrast, the wake of both dorsal fins in bamboo sharks displayed increased net flow velocity in the majority of trials, reflecting a thrust contribution to steady swimming. In bamboo sharks, fluid flow in the wake of the second dorsal fin had higher absolute average velocity than that for first dorsal fin, and this may result from a positive vortex interaction between the first and second dorsal fins. These data suggest that the first dorsal fin in spiny dogfish has primarily a stabilizing function, while the second dorsal fin has a propulsive function. In bamboo sharks, both dorsal fins can contribute thrust and should be considered as propulsive adjuncts to the body during steady

Disentangling the effects of date, individual, and territory quality on the seasonal decline in fitness.

The seasonal timing of reproduction is a major fitness factor in many organisms. Commonly, individual fitness declines with time in the breeding season. We investigated three suggested but rarely tested hypotheses for this seasonal fitness decline: (1) time per se (date hypothesis), (2) late breeders are of lower quality than early ones (individual quality hypothesis), and (3) late breeders are breeding at poorer territories than early breeders (territory quality hypothesis). We used Bayesian variance component analyses to examine reproductive output (breeding success, number fledged, and number of recruits) from repeated observations of female Northern Wheatears (Oenanthe oenanthe) and individual territories from a 20-yr population study. The major part of the observed seasonal decline in reproductive output seemed to be driven by date-related effects, whereas female age and territory type (i.e., known indicators of temporary quality) contributed to a smaller degree. Other, persistent effects linked to individual and territory identity did not show any clear patterns on the seasonal decline in reproductive output. To better disentangle the quality effects (persistent and temporary) of individual and territory from effects caused by the deterioration of the environment we suggest a protocol combining experimental manipulation of breeding time with a variance-covariance partitioning method used here. © 2017 by the Ecological Society of America.

Regions and the Territorial Cohesion

Ioan Ianos

Full Text Available Territorial cohesion is an important target of European Union, constantly promoted by its institutions and their representatives. In the context of the Europe 2020 strategy, one of the most important support documents, the region represents a very important issue, being considered to be the key to its successfulness. The region is seen as a support for the smart growth and all the operational policy concepts try to make use of the spatial potential, by taking better account of the territorial specificities. Two main questions play attention: the need to transform the present-day developmental regions into administrative ones is a priority? What kind of regionalization it must to be promoted? Correlating these issues with already defined territorial cohesion, the administrative region is a real tool for the future territorial development. The experience of the last 14 years asks urgently the building of a new territorial administrative reform, giving competences to regions. For instant, each development region is a construction resulted from a free association of the counties. Their role in the regional development is much reduced one, because their regional councils are not elected; decisions taken at this level are consultative for the social, economical, cultural or political actors.

Chordotonal organs in hemipteran insects: unique peripheral structures but conserved central organization revealed by comparative neuroanatomy.

Hemipteran insects use sophisticated vibrational communications by striking body appendages on the substrate or by oscillating the abdominal tymbal. There has been, however, little investigation of sensory channels for processing vibrational signals. Using sensory nerve stainings and low invasive confocal analyses, we demonstrate the comprehensive neuronal mapping of putative vibration-responsive chordotonal organs (COs) in stink bugs (Pentatomidae and Cydinidae) and cicadas (Cicadidae). The femoral CO (FCO) in stink bugs consists of ventral and dorsal scoloparia, homologous to distal and proximal scoloparia in locusts, which are implicated in joint movement detection and vibration detection, respectively. The ligament of the dorsal scoloparium is distally attached to the accessory extensor muscle, whereas that of the ventral scoloparium is attached to a specialized tendon. Their afferents project to the dorso-lateral neuropil and the central region of the medial ventral association center (mVAC) in the ipsilateral neuromere, where presumed dorsal scoloparium afferents and subgenual organ afferents are largely intermingled. In contrast, FCOs in cicadas have decreased dorsal scoloparium neurons and lack projections to the mVAC. The tymbal CO of stink bugs contains four sensory neurons that are distally attached to fat body cells via a ligament. Their axons project intersegmentally to the dorsal region of mVACs in all neuromeres. Together with comparisons of COs in different insect groups, the results suggest that hemipteran COs have undergone structural modification for achieving faster signaling of resonating peripheral tissues. The conserved projection patterns of COs suggest functional importance of the FCO and subgenual organ for vibrational communications.

The judicialization of territorial politics in Brazil, Colombia and Spain

Directory of Open Access Journals (Sweden)

Helder Ferreira do Vale

2013-08-01

Full Text Available This article explains how judicial review influences intergovernmental political dynamics in Brazil, Colombia and Spain. The argument is developed in light of two questions: how supreme courts have established themselves as pivotal institutions for settling vertical intergovernmental disputes, and how national and subnational politicians use judicial review in order to enhance their own interests. A comparison between the judicial review processes in federal Brazil, quasi-federal Spain, and unitary Colombia provides an answer to these questions. Accounting for the differences in the territorial organization and systems of government among these countries, the article assesses the patterns of judicial review originating from the subnational level. Findings suggest that courts affect the interaction between national and subnational politicians in the three country-cases, but through different patterns of judicialization of territorial politics.

Full Text Available The paper deals with the evolution in the administrations of four Contadi in central and eastern cities of Lombardy (Bergamo, Brescia, Lodi and Mantova. It begins by examining the estate surveys that in the whole area start from the first two decades of the thirteenth century. These surveys will become instruments of knowledge of local territories. In addition it considers the legislation with which the city was seeking to build an active territoriality of the communities in the district. The district is also divided by cities into smaller administrative entities: the rural communities.

Opposing dorsal/ventral stream dynamics during figure-ground segregation.

Wokke, Martijn E; Scholte, H Steven; Lamme, Victor A F

2014-02-01

The visual system has been commonly subdivided into two segregated visual processing streams: The dorsal pathway processes mainly spatial information, and the ventral pathway specializes in object perception. Recent findings, however, indicate that different forms of interaction (cross-talk) exist between the dorsal and the ventral stream. Here, we used TMS and concurrent EEG recordings to explore these interactions between the dorsal and ventral stream during figure-ground segregation. In two separate experiments, we used repetitive TMS and single-pulse TMS to disrupt processing in the dorsal (V5/HMT⁺) and the ventral (lateral occipital area) stream during a motion-defined figure discrimination task. We presented stimuli that made it possible to differentiate between relatively low-level (figure boundary detection) from higher-level (surface segregation) processing steps during figure-ground segregation. Results show that disruption of V5/HMT⁺ impaired performance related to surface segregation; this effect was mainly found when V5/HMT⁺ was perturbed in an early time window (100 msec) after stimulus presentation. Surprisingly, disruption of the lateral occipital area resulted in increased performance scores and enhanced neural correlates of surface segregation. This facilitatory effect was also mainly found in an early time window (100 msec) after stimulus presentation. These results suggest a "push-pull" interaction in which dorsal and ventral extrastriate areas are being recruited or inhibited depending on stimulus category and task demands.

Full Text Available In this paper we focus on the structure and territorial borders of the Baltic Sea region, and examine the key structural elements of the transnational territorial transport system. In this respect, we clarify some terms used in transport geography. For the first time the transport system gets territorially localized, which allows for a broad range of new studies of transnational transportation in the Baltic Sea area. We also identify the main principles of development and operation of international territorial transport systems and present them taking the Baltic Sea region as an example. Our findings, we hope, will have a great practical application for researchers of transport geography, especially those studying international logistics.

Animal interactions and the emergence of territoriality.

Directory of Open Access Journals (Sweden)

Luca Giuggioli

2011-03-01

Full Text Available Inferring the role of interactions in territorial animals relies upon accurate recordings of the behaviour of neighbouring individuals. Such accurate recordings are rarely available from field studies. As a result, quantification of the interaction mechanisms has often relied upon theoretical approaches, which hitherto have been limited to comparisons of macroscopic population-level predictions from un-tested interaction models. Here we present a quantitative framework that possesses a microscopic testable hypothesis on the mechanism of conspecific avoidance mediated by olfactory signals in the form of scent marks. We find that the key parameters controlling territoriality are two: the average territory size, i.e. the inverse of the population density, and the time span during which animal scent marks remain active. Since permanent monitoring of a territorial border is not possible, scent marks need to function in the temporary absence of the resident. As chemical signals carried by the scent only last a finite amount of time, each animal needs to revisit territorial boundaries frequently and refresh its own scent marks in order to deter possible intruders. The size of the territory an animal can maintain is thus proportional to the time necessary for an animal to move between its own territorial boundaries. By using an agent-based model to take into account the possible spatio-temporal movement trajectories of individual animals, we show that the emerging territories are the result of a form of collective animal movement where, different to shoaling, flocking or herding, interactions are highly heterogeneous in space and time. The applicability of our hypothesis has been tested with a prototypical territorial animal, the red fox (Vulpes vulpes.

Full Text Available The article suggests a necessary link between urban planning and territorial organization, in order to, through the synergistic relationship between planning tools and their application to planning, implementing a policy of urban and regional management. By linking the development plan for territorial development plans and categories of land use, this methodology helps to streamline operations at multiple scales. The establishment of this network of instruments and shapes the actions of government action against the rapid and intense increase of only economic forces that shape the territory today, suggesting that it is possible to regulate the action of the housing market through planned interventions, valuing the regional balance, social and environmental - ethical by definition. It is suggested that the possible effects predatory natural and built environment can be reversed or prevented by an action articulating these planning instruments are linked to the development and implementation of plans (and projects at multiple scales, approaching from the regional to the local and metropolitan, from regional policies to sectors, that are incidents in the municipal territory. However, the speed and magnitude of the occupation and transformation of soil occur mainly in periods of heating housing, often jeopardize the balance and environmental quality, natural heritage, urban and landscape. It assumes the argument that the overcoming of undesirable environmental effects, triggered by occupation of the ground guided by the real estate sector fast action can be successful with the articulation of levels of planning and intervention. It is proposed that the complexity of contemporary urban and metropolitan requires the articulation of different scales through the use of innovative urban instruments. By articulating these different scales, at the municipal and other levels supra, contributes to, through a network plan to overcome the undesirable dichotomy

Full Text Available Forty two 2-year-old thoroughbreds were examined clinically at intervals of 15 days during their training for the first race to determine the incidence and the predisposing factors of dorsal metacarpal disease. During the first year 25 horses were followed during 2 months and in the second year the follow up was done for 4 months in 17 . Horses' data like gender, average speed, speed exercise work and trainer were also collected. Dorsal metacarpal disease was diagnosed in 28% and 70,6% of the 2 year-old thoroughbreds in the first and second year of the study, respectively. Total incidence was 45%. The incidence and average speed was not affected by gender. The average speed achieved by affected and none affected horses remained between 16 and 18m/s. On 500 and 700m speed exercise, the average speed of affected horses was higher than of none affected ones (p<0,05. Ten out of 19 horses showed dorsal metacarpal disease signs at the distance of 700m. There was significant difference between trainers regarding the incidence of dorsal metacarpal disease and average speed of their horses. 2-year-olds under care of trainers whose horses had the highest incidence o dorsal metacarpal disease also were the fastest one's. Therefore, fast speed associated with longer distances (700m and trainer are factors that predispose young horses to dorsal metacarpal disease.

The developing dorsal ganglion of the salp Thalia democratica, and the nature of the ancestral chordate brain

Science.gov (United States)

C.Lacalli, T.

1998-01-01

The development of the dorsal ganglion of the salp, Thalia democratica, is described from electron microscope reconstructions up to the stage of central neuropile formation. The central nervous system (CNS) rudiment is initially tubular with an open central canal. Early developmental events include: (i) the formation of a thick dorsal mantle of neuroblasts from which paired dorsal paraxial neuropiles arise; (ii) the differentiation of clusters of primary motor neurons along the ventral margin of the mantle; and (iii) the development from the latter of a series of peripheral nerves. The dorsal paraxial neuropiles ultimately connect to the large central neuropile, which develops later. Direct contact between neuroblasts and muscle appears to be involved in the development of some anterior nerves. The caudal nerves responsible for innervating more distant targets in the posterior part of the body develop without such contacts, which suggests that a different patterning mechanism may be employed in this part of the neuromuscular system. The results are compared with patterns of brain organization in other chordates. Because the salp CNS is symmetrical and generally less reduced than that of ascidian larvae, it is more easily compared with the CNS of amphioxus and vertebrates. The dorsal paraxial centres in the salp resemble the dorsolateral tectal centres in amphioxus in both position and organization; the central neuropile in salps likewise resembles the translumenal system in amphioxus. The neurons themselves are similar in that many of their neurites appear to be derived from the apical surface instead of the basal surface of the cell. Such neurons, with extensively developed apical neurites, may represent a new cell type that evolved in the earliest chordates in conjunction with the formation of translumenal or intralumenal integrative centres. In comparing the salp ganglion with vertebrates, we suggest that the main core of the ganglion is most like the mes

Responsibilities and Limits of Local Government Actions against Users of Public Services of Planning and Sustainable Territorial Development in Romania

Directory of Open Access Journals (Sweden)

Bogdan Suditu

2014-02-01

Full Text Available In the context of the changes that have occurred in the Romanian society, the public authorities are required to play a coordinating role in providing the framework for a sustainable and balanced development of the national territory, and to ensure the quality of life of the citizens. In order to achieve these goals of social responsibility, the public administration authorities must build and adapt the tools of public territorial action based on their specificity and within the existing legal framework and resources,. Thus, the study shows the national and European context that frames the actions of public administration for what concerns the sustainable territorial development. It analyzes the characteristics of administrative-territorial structures of Romania, highlighting their socio-demographic diversity and the territorial forms of institutional cooperation. The approach of these issues is based in the first instance on an analysis of the European strategic documents in the field, as well as on the national regulations concerning the organization and functioning of public administration and territorial planning. The implementation of decentralization and local public autonomy has led to the capitalization of the local potential of some administrative divisions and caused a competition and a difficult cooperation between them. By analogy with the provisions of the quality standards regarding the responsibilities of the organizations towards customers, the study illustrates and analyzes the responsibilities and limits of public administration authorities in promoting sustainable development, territorial equity and the quality of life for the users of public services, i.e. the community members.

Fiehler, Katja; Burke, Michael; Bien, Siegfried; Röder, Brigitte; Rösler, Frank

2009-01-01

The primate dorsal pathway has been proposed to compute vision for action. Although recent findings suggest that dorsal pathway structures contribute to somatosensory action control as well, it is yet not clear whether or not the development of dorsal pathway functions depends on early visual experience. Using functional magnetic resonance imaging, we investigated the pattern of cortical activation in congenitally blind and matched blindfolded sighted adults while performing kinesthetically guided hand movements. Congenitally blind adults activated similar dorsal pathway structures as sighted controls. Group-specific activations were found in the extrastriate cortex and the auditory cortex for congenitally blind humans and in the precuneus and the presupplementary motor area for sighted humans. Dorsal pathway activity was in addition observed for working memory maintenance of kinesthetic movement information in both groups. Thus, the results suggest that dorsal pathway functions develop in the absence of vision. This favors the idea of a general mechanism of movement control that operates regardless of the sensory input modality. Group differences in cortical activation patterns imply different movement control strategies as a function of visual experience.

Personal floatation devices maintain either a semirecumbent flotation posture with the head and upper chest out of the water or a horizontal flotation posture with the dorsal head and whole body immersed. The contribution of dorsal head and upper chest immersion to core cooling in cold water was isolated when the confounding effect of shivering heat production was inhibited with meperidine (Demerol, 2.5 mg/kg). Six male volunteers were immersed four times for up to 60 min, or until esophageal temperature = 34 degrees C. An insulated hoodless dry suit or two different personal floatation devices were used to create four conditions: 1) body insulated, head out; 2) body insulated, dorsal head immersed; 3) body exposed, head (and upper chest) out; and 4) body exposed, dorsal head (and upper chest) immersed. When the body was insulated, dorsal head immersion did not affect core cooling rate (1.1 degrees C/h) compared with head-out conditions (0.7 degrees C/h). When the body was exposed, however, the rate of core cooling increased by 40% from 3.6 degrees C/h with the head out to 5.0 degrees C/h with the dorsal head and upper chest immersed (P immersed (approximately 10%). The exaggerated core cooling during dorsal head immersion (40% increase) may result from the extra heat loss affecting a smaller thermal core due to intense thermal stimulation of the body and head and resultant peripheral vasoconstriction. Dorsal head and upper chest immersion in cold water increases the rate of core cooling and decreases potential survival time.

After the political constitution issued in 1991 and the gamma of laws that develop it, the possible environmental participation in Colombia is a legitimate participation that does not contribute to building of citizenship. In Medellin, the environmental participation, in planning the territorial arrangement, is low qualified for it presents grave faults in its structural attributes. As shown by the indicators, the representatively, legitimacy, the level of environmental information, the territorial associations, the communicative competence and the participation pertinence, present a low level of contribution to a substantive, democratic, involving, organic, co-responsible and informative environmental participation

Insights from event-related potentials into the temporal and hierarchical organization of the ventral and dorsal streams of the visual system in selective attention.

Science.gov (United States)

Martín-Loeches, M; Hinojosa, J A; Rubia, F J

1999-11-01

The temporal and hierarchical relationships between the dorsal and the ventral streams in selective attention are known only in relation to the use of spatial location as the attentional cue mediated by the dorsal stream. To improve this state of affairs, event-related brain potentials were recorded while subjects attended simultaneously to motion direction (mediated by the dorsal stream) and to a property mediated by the ventral stream (color or shape). At about the same time, a selection positivity (SP) started for attention mediated by both streams. However, the SP for color and shape peaked about 60 ms later than motion SP. Subsequently, a selection negativity (SN) followed by a late positive component (LPC) were found simultaneously for attention mediated by both streams. A hierarchical relationship between the two streams was not observed, but neither SN nor LPC for one property was completely insensitive to the values of the other property.

2015-01-01

Full Text Available Backgound and Purpose: Computerized tomography (CT perfusion (or CTP source images from CT scanners with small detector widths can be used to create a dynamic CT angiogram (CTA similar to digital subtraction angiography (DSA. Because CTP studies use a single intravenous injection, all arterial territories enhance simultaneously, and individual arterial territories [i.e., anterior cerebral artery (ACA, middle cerebral artery (MCA, and posterior cerebral artery (PCA] cannot be delineated. This limits the ability to assess collateral flow patterns on dynamic CTAs. The aim of this study was to devise and test a postprocessing method to selectively color-label the major arterial territories on dynamic CTA. Materials and Methods: We identified 22 acute-stroke patients who underwent CTP on a 320-slice CT scanner within 6 h from symptom onset. For each case, two investigators independently generated an arterial territory map from CTP bolus arrival maps using a semiautomated method. The volumes of the arterial territories were calculated for each map and the average relative difference between these volumes was calculated for each case as a measure of interrater agreement. Arterial territory maps were superimposed on the dynamic CTA to create a vessel-selective dynamic CTA with color-coding of the main arterial territories. Two experts rated the arterial territory maps and the color-coded CTAs for consistency with expected arterial territories on a 3-point scale (excellent, moderate, poor. Results: Arterial territory maps were generated for all 22 patients. The median difference in arterial territory volumes between investigators was 2.2% [interquartile range (IQR 0.6-8.5%]. Based on expert review, the arterial territory maps and the vessel-selective dynamic CTAs showed excellent consistency with the expected arterial territories in 18 of 22 patients, moderate consistency in 2 patients, and poor consistency in another 2 patients. Conclusion: Using a

Mammal-like organization of the avian midbrain central gray and a reappraisal of the intercollicular nucleus.

Directory of Open Access Journals (Sweden)

Marcy A Kingsbury

Full Text Available In mammals, rostrocaudal columns of the midbrain periaqueductal gray (PAG regulate diverse behavioral and physiological functions, including sexual and fight-or-flight behavior, but homologous columns have not been identified in non-mammalian species. In contrast to mammals, in which the PAG lies ventral to the superior colliculus and surrounds the cerebral aqueduct, birds exhibit a hypertrophied tectum that is displaced laterally, and thus the midbrain central gray (CG extends mediolaterally rather than dorsoventrally as in mammals. We therefore hypothesized that the avian CG is organized much like a folded open PAG. To address this hypothesis, we conducted immunohistochemical comparisons of the midbrains of mice and finches, as well as Fos studies of aggressive dominance, subordinance, non-social defense and sexual behavior in territorial and gregarious finch species. We obtained excellent support for our predictions based on the folded open model of the PAG and further showed that birds possess functional and anatomical zones that form longitudinal columns similar to those in mammals. However, distinguishing characteristics of the dorsal/dorsolateral PAG, such as a dense peptidergic innervation, a longitudinal column of neuronal nitric oxide synthase neurons, and aggression-induced Fos responses, do not lie within the classical avian CG, but in the laterally adjacent intercollicular nucleus (ICo, suggesting that much of the ICo is homologous to the dorsal PAG.

Nuclear: an energy in territories

Le Ngoc, Boris

2016-01-01

After having briefly outlined that introducing a relationship between geography and nuclear energy is a quite recent approach, and by often quoting a researcher (Teva Meyer) specialised in Swedish energy issues, the author briefly discusses how nuclear energy structures territories through meshing and 'polarisation' effects, and economic and social impacts. He also discusses whether territories then become dependent on nuclear activity, what happens when a nuclear plant stops, how the existence of a nuclear plant becomes an identity market for a territory, and how material flows also deal with geography. In the last part, the author notices that in Germany, nuclear industry is considered as an industry like any other one. He finally outlines that geography could be useful to achieve energy transition

Full Text Available Even for the evident "similarities" with the results of scientific and technological evolution of the "network society", during the 90s the network metaphor has established itself as a dominant "image", to which link the understanding/interpretation (project of the contemporary complexity (city/territory/society. This resulted in new descriptions/interpretations (projects of the city and of the territory that move from the "material" and "immaterial" organization of the network itself.However, not always the "reduction" operated within planning was able to highlight limitations and contradictions inherent in the network metaphor as an interpretative key.In reality, the planning “speech” seems to focus primarily on "technical" issues – which certainly are not irrelevant – as congestion of flows, inadequacy of logistics platforms and, more generally, as regards the Italian case, on the serious and continuing infrastructure deficit: all factors that determine an undeniable impact on efficiency and competitiveness, on accessibility to services and on the timing of city use.But what, however, seems to be necessary is the overcoming of the still too sectoral approach towards a truly integrated planning pattern.This difficulty can be traced to some issues/problems of a structural nature that, historically, characterized the political-cultural and disciplinary Italian context. For example, despite the obvious consequences, measures regarding infrastructures tend to be made separately from the planning system. This is derived from the organization in different sectors that historically characterized public administration in general. In addition, we have particularistic logic of both vertical and horizontal type, that is the division of powers between administrative bodies of different levels or between structures of the same sector.This limits related to the issue of segmentation are more noticeable if you switch from ordinary activities to the

Cultural territory and the transformation of the forest into a social artifact

Directory of Open Access Journals (Sweden)

Marcos Pereira Magalhães

2013-08-01

Full Text Available The perspective of landscape archaeology views all cultural territory as a space whose landscapes are constructed and environments transformed into social artifacts. The space that a society uses consists of localities with diverse material objects and natural resources that make up a cultural territory with related anthropogenic environments. Much like material artifacts, the landscapes reproduce the spiritual, political, and economic representations of a society. Recent archaeological studies conducted in the region of Porto Trombetas (Pará state have looked into the manner in which societies related to the Konduri ceramic tradition altered the environment by modifying, planting, or cultivating selected plant species according to their particular cultural norms. A botanical inventory and archaeological excavations carried out at the site Greig II, associated with the Konduri tradition, indicate how specific cultural activities create more productive environments as well as familiar landscapes with a specific cultural identity. Independent of the possible stylistic variations present in material culture, societies construct landscapes where they organize and create social and territorial identities.

This paper highlights the rationale for exclusive territories in a model of repeated interaction between competing supply chains. We show that with observable contracts exclusive territories have two countervailing effects on manufacturers' incentives to sustain tacit collusion. First, granting local monopolies to retailers distributing a given brand softens inter- and intrabrand competition in a one-shot game. Hence, punishment profits are larger, thereby rendering deviation more profitable....

and territory protection from mass-destruction weapon. Organization of actions on population and territory protection is caused on geographical location of Tajikistan. There is a number of some states near Tajikistan that have nuclear weapon: India, China, Pakistan. The basic actions for protection of the population and territories from weapons of mass destruction are: maintenance and accumulation of means of an individual defense, creation of stocks; creation and restoration of protective constructions of a civil defense; evacuation actions planning; restoration of system of monitoring and the laboratory control of a civil defense of Republic Tajikistan; according to the Government Regulation N 527 and dated on 31"s"t of October, 2008 the 'Emergency situations and civil defense system development 2009-2014' Program was adopted. According to the Plan of the events within this Programme Committee of emergency situations and civil defense under the Government of Republic of Tajikistan provides a stage-by-stage realization of the actions for protection of population and territories from mass-destruction weapon. One of the important actions is provision and accumulation of the means of personal protection, keeping of this means. The means of personal protections are laboratory tested by the specialists of the Committee of emergency situations and civil defense. Analytical data of the Committee of emergency situations and civil defense allows making some conclusions concerning experienced storage of the means of personal protection. A general analysis of laboratory test indicates that: laboratory tests of filtering boxes indicate the preservation of air flow resistance and waterproof due to the adherence to the rules of keeping; laboratory tests of the front parts of the gas masks and their hardness and waterproof, and the waterproof of the valves show that the front part is dependent on meteorological character of the region of storage at long-term keeping.

Buccal mucosal graft (BMG) substitution urethroplasty has become popular in the management of intractable anterior urethral strictures with good results. Excellent long-term results have been reported by both dorsal and ventral onlay techniques. Asopa reported a successful technique for dorsal placement of BMG in long anterior urethral strictures through a ventral sagittal approach. To evaluate prospectively the results and advantages of dorsal BMG urethroplasty for recurrent anterior urethral strictures by a ventral sagittal urethrotomy approach (Asopa technique). From December 2002 to December 2007, a total of 58 men underwent dorsal BMG urethroplasty by a ventral sagittal urethrotomy approach for recurrent urethral strictures. Forty-five of these patients with a follow-up period of 12-60 mo were prospectively evaluated, and the results were analysed. The urethra was split twice at the site of the stricture both ventrally and dorsally without mobilising it from its bed, and the buccal mucosal graft was secured in the dorsal urethral defect. The urethra was then retubularised in one stage. The overall results were good (87%), with a mean follow-up period of 42 mo. Seven patients developed minor wound infection, and five patients developed fistulae. There were six recurrences (6:45, 13%) during the follow-up period of 12-60 mo. Two patients with a panurethral stricture and four with bulbar or penobulbar strictures developed recurrences and were managed by optical urethrotomy and self-dilatation. The medium-term results were as good as those reported with the dorsal urethrotomy approach. Long-term results from this and other series are awaited. More randomised trials and meta-analyses are needed to establish this technique as a procedure of choice in future. The ventral sagittal urethrotomy approach is easier to perform than the dorsal urethrotomy approach, has good results, and is especially useful in long anterior urethral strictures.

BMPs regulate msx gene expression in the dorsal neuroectoderm of Drosophila and vertebrates by distinct mechanisms.

In a broad variety of bilaterian species the trunk central nervous system (CNS) derives from three primary rows of neuroblasts. The fates of these neural progenitor cells are determined in part by three conserved transcription factors: vnd/nkx2.2, ind/gsh and msh/msx in Drosophila melanogaster/vertebrates, which are expressed in corresponding non-overlapping patterns along the dorsal-ventral axis. While this conserved suite of "neural identity" gene expression strongly suggests a common ancestral origin for the patterning systems, it is unclear whether the original regulatory mechanisms establishing these patterns have been similarly conserved during evolution. In Drosophila, genetic evidence suggests that Bone Morphogenetic Proteins (BMPs) act in a dosage-dependent fashion to repress expression of neural identity genes. BMPs also play a dose-dependent role in patterning the dorsal and lateral regions of the vertebrate CNS, however, the mechanism by which they achieve such patterning has not yet been clearly established. In this report, we examine the mechanisms by which BMPs act on cis-regulatory modules (CRMs) that control localized expression of the Drosophila msh and zebrafish (Danio rerio) msxB in the dorsal central nervous system (CNS). Our analysis suggests that BMPs act differently in these organisms to regulate similar patterns of gene expression in the neuroectoderm: repressing msh expression in Drosophila, while activating msxB expression in the zebrafish. These findings suggest that the mechanisms by which the BMP gradient patterns the dorsal neuroectoderm have reversed since the divergence of these two ancient lineages.

Geostrategy of Economic Spaces: Innovation and Change in Latin America Territorial Administration

Directory of Open Access Journals (Sweden)

Euripedes Falcão Vieira

2008-10-01

Full Text Available In this essay we analyze the geostrategy of economic spaces in the sphere of new links in the global economy, placing Latin America in the scenario of the new world order. The geostrategic dimension of economic spaces includes spatial redefinitions as a result of new global strategies of the major transnational corporations. This is, therefore, of a space-time configuration of scenarios in the articulation between the importance of the place, action site, and expression of power. Territorial administration adopts new outlines, sharing and is linked to the logistics of market interests. In the new configuration of interests of global economics, the spatial barriers are set aside and global places are created, representing fragmentations of territorialized space. Territorialization of global productive spaces represents deterritorialization of national spaces. Forms of power and influence of power radiate from them in all directions. Power and administration of territory in the large complex economic and political organisms – regional blocks – confront each member’s historic reality, the inequalities of the rates of development, culture and social levels. These realities are hard to harmonize and eventually categorize hegemonic centers of power and a national fringe of dependence. Global geostrategy, therefore, takes over, redefines and reorders productive circulation spaces, establishing new relations of power and administration of territories. Historically, Latin America continued to depend heavily on the economic order established by the colonizing countries and this dependence gradually shifted to the world financial supremacies. This dependence intensified the indebtedness process that today characterizes the so-called market of foreign debts, with significant reflections on the internal social order.

bullwinkle and shark regulate dorsal-appendage morphogenesis in Drosophila oogenesis.

Tran, David H; Berg, Celeste A

2003-12-01

bullwinkle (bwk) regulates embryonic anteroposterior patterning and, through a novel germline-to-soma signal, morphogenesis of the eggshell dorsal appendages. We screened for dominant modifiers of the bullwinkle mooseantler eggshell phenotype and identified shark, which encodes an SH2-domain, ankyrin-repeat tyrosine kinase. At the onset of dorsal-appendage formation, shark is expressed in a punctate pattern in the squamous stretch cells overlying the nurse cells. Confocal microscopy with cell-type-specific markers demonstrates that the stretch cells act as a substrate for the migrating dorsal-appendage-forming cells and extend cellular projections towards them. Mosaic analyses reveal that shark is required in follicle cells for cell migration and chorion deposition. Proper shark RNA expression in the stretch cells requires bwk activity, while restoration of shark expression in the stretch cells suppresses the bwk dorsal-appendage phenotype. These results suggest that shark plays an important downstream role in the bwk-signaling pathway. Candidate testing implicates Src42A in a similar role, suggesting conservation with a vertebrate signaling pathway involving non-receptor tyrosine kinases.

Attention modulates the dorsal striatum response to love stimuli.

Langeslag, Sandra J E; van der Veen, Frederik M; Röder, Christian H

2014-02-01

In previous functional magnetic resonance imaging (fMRI) studies concerning romantic love, several brain regions including the caudate and putamen have consistently been found to be more responsive to beloved-related than control stimuli. In those studies, infatuated individuals were typically instructed to passively view the stimuli or to think of the viewed person. In the current study, we examined how the instruction to attend to, or ignore the beloved modulates the response of these brain areas. Infatuated individuals performed an oddball task in which pictures of their beloved and friend served as targets and distractors. The dorsal striatum showed greater activation for the beloved than friend, but only when they were targets. The dorsal striatum actually tended to show less activation for the beloved than the friend when they were distractors. The longer the love and relationship duration, the smaller the response of the dorsal striatum to beloved-distractor stimuli was. We interpret our findings in terms of reinforcement learning. By virtue of using a cognitive task with a full factorial design, we show that the dorsal striatum is not activated by beloved-related information per se, but only by beloved-related information that is attended.

The anatomic distribution and potential arterial flow patterns of the circumflex scapular artery were investigated by Microfil injection. These studies demonstrated that the circumflex scapular artery lies within the dorsal thoracic fascia, which plays a significant role in the circulation of the overlying skin and subcutaneous tissue. We conclude that scapular/parascapular flaps are fasciocutaneous flaps, the dorsal thoracic fascia can be transferred as a free flap without its overlying skin and subcutaneous tissue, and intercommunication exists between the myocutaneous perforators of the latissimus dorsi myocutaneous flap and the vascular plexus of the dorsal thoracic fascia. We present microvascular cases in which the vascular properties of the dorsal thoracic fascia facilitated wound closure with free fascia flaps or expanded cutaneous or myocutaneous flaps.

Innovative model of development of traditionally industrial territories

2012-09-01

Full Text Available The consideration in this paper is given to innovative model of development of traditionally industrial territories. We emphasize the following basic approaches to the employment of innovative potential of territories: diversification and restructuring of local economy, integration and disintegration of life-sustaining activity of neighboring territories, progressive economic advance, as well as simultaneous combination of several approaches (mixed model. Progressive model of development is sufficiently popular and is related tothe increasing already existing potential of territories. In practice,it doesn’t generally suppose essential changes in sectoral structure of local economy and means developing existing productions and spheres of activity of territory. Mixed model of structural transformations is characterized through the fact, that it supposes simultaneous use of different elements from the models counted. It allows: firstly, to adopt in a bigger extent a complex of measures to conditions of certain territory; secondly, to take into account a broader range of exogenous and endogenous factors; thirdly, to raise the effectiveness of the program of structural transformations being realized

Energetic cost of feeding territories in an Hawaiian honeycreeper.

Carpenter, F Lynn; MacMillen, Richard E

1976-09-01

By analysis of time budgets the daily energy expenditure in territorial individuals of a Hawaiian honeycreeper (Vestiaria coccinea, Fam. Drepanididae) were estimated during the nonbreeding season and compared to that of nonterritorial individuals. The mean rise in living costs was 2.3 kcal/24 h or 17% of the nonterritorial energy budget. The most costly territorial behavior was advertisement rather than chasing, and total territorial cost was seen to be little affected by the number of intruders or the size of the territory. These results are compared with data on feeding (nonbreeding) territories of other nectar-feeding birds. The suggestion is made that hummingbirds may be more likely to develop nonbreeding territorial behavior in any set of environmental circumstances than are honeycreepers because of relatively lower total cost of advertisement plus chasing.

Compound dorsal dislocation of lunate with trapezoid fracture

2016-12-01

Full Text Available We report about a dorsal dislocation of the lunate accompanied by a trapezoid fracture in a 41-year old male patient after a motorcycle accident. The lunate dislocation with no dorsal or volar intercalated segment instability (DISI, VISI was diagnosed by x-ray whereas the trapezoid fracture was only diagnosable by computed tomography. A closed reduction and internal fixation of the lunate by two Kirschner wires was performed, the trapezoid fracture was conservatively treated. Surgery was followed by immobilization, intense physiotherapy and close follow-up. Even though complaints such as swelling and pain subsided during the course of rehabilitation, partial loss of strength and range of motion remained even after 16 months. In conclusion, a conservative treatment of trapezoid fractures seems to be sufficient in most cases. Closed reduction with Kwire fixation led to an overall satisfactory result in our case. For dorsal lunate dislocations in general, open reduction should be performed when close reduction is unsuccessful or DISI/VISI are observed in radiographs after attempted close reduction.

Garcia and Associates (GANDA) was contracted by the Lawrence Livermore National Laboratory (LLNL) to collect information on golden eagle (Aquila chrysaetos) use of Site 300. During 2014, we conducted surveys at Site 300 and for an area including a 10-mile radius of Site 300. Those surveys documented 42 golden eagle territories including two territories that overlapped with Site 300. These were named ‘Tesla’ and ‘Linac Road’. In 2015, we conducted surveys to refine the territory boundaries of golden eagle territories that overlapped with Site 300 and to document eagle activity at Site 300.

Assessment of brain-damaged subjects presenting with dissociated repetition deficits after selective injury to either the left dorsal or ventral auditory pathways can provide further insight on their respective roles in verbal repetition. We evaluated repetition performance and its neural correlates using multimodal imaging (anatomical MRI, DTI, fMRI, and(18)FDG-PET) in a female patient with transcortical motor aphasia (TCMA) and in a male patient with conduction aphasia (CA) who had small contiguous but non-overlapping left perisylvian infarctions. Repetition in the TCMA patient was fully preserved except for a mild impairment in nonwords and digits, whereas the CA patient had impaired repetition of nonwords, digits and word triplet lists. Sentence repetition was impaired, but he repeated novel sentences significantly better than clichés. The TCMA patient had tissue damage and reduced metabolism in the left sensorimotor cortex and insula. DTI showed damage to the left temporo-frontal and parieto-frontal segments of the arcuate fasciculus (AF) and part of the left ventral stream together with well-developed right dorsal and ventral streams, as has been reported in more than one-third of females. The CA patient had tissue damage and reduced metabolic activity in the left temporoparietal cortex with additional metabolic decrements in the left frontal lobe. DTI showed damage to the left temporo-parietal and temporo-frontal segments of the AF, but the ventral stream was spared. The direct segment of the AF in the right hemisphere was also absent with only vestigial remains of the other dorsal subcomponents present, as is often found in males. fMRI during word and nonword repetition revealed bilateral perisylvian activation in the TCMA patient suggesting recruitment of spared segments of the left dorsal stream and right dorsal stream with propagation of signals to temporal lobe structures suggesting a compensatory reallocation of resources via the ventral streams.

Early life experience influences stress reactivity and mental health through effects on cognitive-emotional functions that are, in part, linked to gene expression in the dorsal and ventral hippocampus. The hippocampal dentate gyrus (DG) is a major site for experience-dependent plasticity associated with sustained transcriptional alterations, potentially mediated by epigenetic modifications. Here, we report comprehensive DNA methylome, hydroxymethylome and transcriptome data sets from mouse dorsal and ventral DG. We find genome-wide transcriptional and methylation differences between dorsal and ventral DG, including at key developmental transcriptional factors. Peripubertal environmental enrichment increases hippocampal volume and enhances dorsal DG-specific differences in gene expression. Enrichment also enhances dorsal-ventral differences in DNA methylation, including at binding sites of the transcription factor NeuroD1, a regulator of adult neurogenesis. These results indicate a dorsal-ventral asymmetry in transcription and methylation that parallels well-known functional and anatomical differences, and that may be enhanced by environmental enrichment.

Spaces of Territorialization in Fritz Lang’s Film Metropolis (1927

2015-04-01

Full Text Available This paper investigates the relationship between film, architecture and the city in Fritz Lang’s film Metropolis by analyzing and interpreting its spatial concepts as a text of Weimar culture. Locating the study in the context of philosophy, theory of text, and cultural analysis, the main hypothesis of this paper is that the urban and architectural spaces of Metropolis are based on the concept of territorialization (arborescent model of organization of a totalitarian capitalist system through the reduction of real or fictional deterritorialization to a definitive and closed territory of totalitarianism. Developing this hypothesis with historical, comparative, and analytical methods, the aim of this paper is to investigate the relationship between narrative, ideology, and space in Metropolis. How is the ideology of Weimar culture represented by spatial structures in Metropolis? What are the relations of acts of territorialization, narrative, and the rhythmical structures of spaces of modern culture in this film? How are social practices inscribed in the spatial structures of the film, marking the totalitarian system and its terrorist horror on one side, and resistance to the totalitarian system on the other, trying to abolish the active/passive dichotomy? These are the key questions of this study. Its theoretical starting point comes from the works of Gilles Deleuze, Félix Guattari, Luce Irigaray, Erwin Panofsky, and Rosalind Krauss.

Age-related reduction in microcolumnar structure correlates with cognitive decline in ventral but not dorsal area 46 of the rhesus monkey.

The age-related decline in cognitive function that is observed in normal aging monkeys and humans occurs without significant loss of cortical neurons. This suggests that cognitive impairment results from subtle, sub-lethal changes in the cortex. Recently, changes in the structural coherence in mini- or microcolumns without loss of neurons have been linked to loss of function. Here we use a density map method to quantify microcolumnar structure in both banks of the sulcus principalis (prefrontal cortical area 46) of 16 (ventral) and 19 (dorsal) behaviorally tested female rhesus monkeys from 6 to 33 years of age. While total neuronal density does not change with age in either of these banks, there is a significant age-related reduction in the strength of microcolumns in both regions on the order of 40%. This likely reflects a subtle but definite loss of organization in the structure of the cortical microcolumn. The reduction in strength in ventral area 46 correlates with cognitive impairments in learning and memory while the reduction in dorsal area 46 does not. This result is congruent with published data attributing cognitive functions to ventral area 46 that are similar to our particular cognitive battery which does not optimally tap cognitive functions attributed to dorsal area 46. While the exact mechanisms underlying this loss of microcolumnar organization remain to be determined, it is plausible that they reflect age-related alterations in dendritic and/or axonal organization which alter connectivity and may contribute to age-related declines in cognitive performance.

A territorial understanding of sustainability in public development

Sustainability theories in European Union (EU) development policies are facing significant challenges: it is difficult to transmit context-specific, publicly communicable messages; the recent development policies strengthen the concurrent development paradigm of economic growth and competitiveness; 'climate change' became a more popular environmental integration term than sustainability in the last few years. However, due to the recent crises of the economic growth, there is a great chance to reintroduce a sustainability-based development. A territorial/regional understanding of sustainability can also be an answer for the current challenges, a platform for refreshing the concept with relevant, specific messages that are close to the everyday life. This paper summarises the 'territorial system'-based basic principles of territorial sustainability in a model called AUTHARSIIV (AUTonomy, HARmony, Solidarity, Innovation, Identity and Values). This is a supplementary sustainability content specified for the context of spatial/regional development or planning. The paper also examines the presence of 'general and territorial sustainability' in regional development programmes, and case studies on applying the territorial sustainability principles in planning, assessment, and implementation. According to the results, sustainability is rarely adapted to the conditions of a given sector or a region, and the territorial aspect of sustainability is underrepresented even in territorial programmes. Therefore, the paper proposes a new planning and assessment system that is based on a set of regionally legitimate sustainability values.

Amnioserosa cell constriction but not epidermal actin cable tension autonomously drives dorsal closure.

Science.gov (United States)

Pasakarnis, Laurynas; Frei, Erich; Caussinus, Emmanuel; Affolter, Markus; Brunner, Damian

2016-11-01

Tissue morphogenesis requires coordination of multiple force-producing components. During dorsal closure in fly embryogenesis, an epidermis opening closes. A tensioned epidermal actin/MyosinII cable, which surrounds the opening, produces a force that is thought to combine with another MyosinII force mediating apical constriction of the amnioserosa cells that fill the opening. A model proposing that each force could autonomously drive dorsal closure was recently challenged by a model in which the two forces combine in a ratchet mechanism. Acute force elimination via selective MyosinII depletion in one or the other tissue shows that the amnioserosa tissue autonomously drives dorsal closure while the actin/MyosinII cable cannot. These findings exclude both previous models, although a contribution of the ratchet mechanism at dorsal closure onset remains likely. This shifts the current view of dorsal closure being a combinatorial force-component system to a single tissue-driven closure event.

Dorsal pancreatic agenesis is a very rare congenital anomaly. Unilateral renal agenesis, on the other hand, is a relatively common congenital anomaly, although its etiology is not fully understood. Renal and pancreatic embryologic development appears to be nonrelated. We report a case of a 34-year-old man who was referred to our hospital for evaluation of cholestasis and microalbuminuria. Ultrasound and magnetic resonance imaging examinations showed empty right renal fossa and absence of the pancreatic neck, body, and tail. Our case report is the second case of a dorsal pancreatic agenesis and unilateral renal agenesis in a young male patient.

Primary afferent terminal sprouting after a cervical dorsal rootlet section in the macaque monkey.

Science.gov (United States)

Darian-Smith, Corinna

2004-03-01

We examined the role of primary afferent neurons in the somatosensory cortical "reactivation" that occurs after a localized cervical dorsal root lesion (Darian-Smith and Brown [2000] Nat. Neurosci. 3:476-481). After section of the dorsal rootlets that enervate the macaque's thumb and index finger (segments C6-C8), the cortical representation of these digits was initially silenced but then re-emerged for these same digits over 2-4 postlesion months. Cortical reactivation was accompanied by the emergence of physiologically detectable input from these same digits within dorsal rootlets bordering the lesion site. We investigated whether central axonal sprouting of primary afferents spared by the rhizotomy could mediate this cortical reactivation. The cortical representation of the hand was mapped electrophysiologically 15-25 weeks after the dorsal rootlet section to define this reactivation. Cholera toxin subunit B conjugated to horseradish peroxidase was then injected into the thumb and index finger pads bilaterally to label the central terminals of any neurons that innervated these digits. Primary afferent terminal proliferation was assessed in the spinal dorsal horn and cuneate nucleus at 7 days and 15-25 postlesion weeks. Labeled terminal bouton distributions were reconstructed and the "lesion" and control sides compared within each monkey. Distributions were significantly larger on the side of the lesion in the dorsal horn and cuneate nucleus at 15-25 weeks after the dorsal rootlet section, than those mapped only 7 days postlesion. Our results provide direct evidence for localized sprouting of spared (uninjured) primary afferent terminals in the dorsal horn and cuneate nucleus after a restricted dorsal root injury.

This article intends to manifest some conceptual and methodological questions around spacetime, space and territory, sustainability, social agent, territoriality. It is necessary to overcome the dichotomy space without time and time without space and to un think the world of the social, leaving out the analysis of problems that overcome the fields of the disciplines. The most appropriate approach would be to recognize the existence of a spacetime dimension, or if one wants, time space and to define the geography as a social science that considers the territory like a social construction through the spacetime

Full Text Available This paper aims at introducing the debate about the concepts of "space", "territory", "territoriality", "place" and their possible responsibility in the analysis of political subjects, especially in connection with an Argentine unemployment movement: the CTD Aníbal Verón. First of all, we deal with the debate about whether the space can be thought of as a political constituting dimensión or whether it is enough for it to be considered a conflict manifestation, limit demarcation and access control; the space built being understood as territory. Secondly, we also carry out an analysis of the relation between subjects and space, their appropriation and the meaning they give it, involving identity relations which are often analyzed through the category of place. Attention will be paid to two of the various practices which construct places [in terms of identity] in the territories built/appropriated by the organization: the neighborhood and the picket

Foraging Habitat Distributions Affect Territory Size and Shape in the Tuamotu Kingfisher

Full Text Available I studied factors influencing territory configuration in the Tuamotu kingfisher (Todiramphus gambieri. Radiotelemetry data were used to define territory boundaries, and I tested for effects on territory size and shape of landscape habitat composition and foraging patch configuration. Tuamotu kingfisher territories were larger in areas with reduced densities of coconut plantation foraging habitat, and territories were less circular in the study site that had a single slender patch of foraging habitat. Maximum territory length did not differ between study sites, however, which suggested that the size of Tuamotu kingfisher territories might be bounded by the combined influence of maximum travel distances and habitat configurations. Results also suggested that birds enlarge territories as they age. Together, results supported previous work indicating that territory configurations represent a balance between the costs of defending a territory and gains from territory ownership.

Detection of genes regulated by Lmx1b during limb dorsalization.

Feenstra, Jennifer M; Kanaya, Kohei; Pira, Charmaine U; Hoffman, Sarah E; Eppey, Richard J; Oberg, Kerby C

2012-05-01

Lmx1b is a homeodomain transcription factor that regulates dorsal identity during limb development. Lmx1b knockout (KO) mice develop distal ventral-ventral limbs. Although induction of Lmx1b is linked to Wnt7a expression in the dorsal limb ectoderm, the downstream targets of Lmx1b that accomplish limb dorsalization are unknown. To identify genes targeted by Lmx1b, we compared gene arrays from Lmx1b KO and wild type mouse limbs during limb dorsalization, i.e., 11.5, 12.5, and 13.5 days post coitum. We identified 54 target genes that were differentially expressed in all three stages. Several skeletal targets, including Emx2, Matrilin1 and Matrilin4, demonstrated a loss of scapular expression in the Lmx1b KO mice, supporting a role for Lmx1b in scapula development. Furthermore, the relative abundance of extracellular matrix-related soft tissue targets regulated by Lmx1b, such as collagens and proteoglycans, suggests a mechanism that includes changes in the extracellular matrix composition to accomplish limb dorsalization. Our study provides the most comprehensive characterization of genes regulated by Lmx1b during limb development to-date and provides targets for further investigation. © 2012 The Authors.

Territorial structure of tourism in Guatemala

Álvaro Sánchez Crispín

Full Text Available The aim of this paper is to reveal the nuclei, flows and surfaces generated by tourism in Guatemala that, nowadays, constitute the basis for the promotion of the country in the international market. Following the trend in Central America, and after a long civil war, Guatemala is encouraging the growth of its tourism economy. The starting point of this research is rooted in the fact that there are only a handful of places, distributed over the Guatemalan territory, that articulate the tourist flows (constituted mainly by international visitors and onto which tourism surfaces are being constructed. We assume that this territorial structure is still weak, does not include all areas of the country and it is mostly dependant on regional emitting markets. The context of the territorial structure of tourism in Guatemala suggests that all countries in the region are competing to get access to the international tourism market and that this competition will be decided in favour of those nations that mastermind the administration of their natural and cultural resources. At the end of the text, we comment on the basics of the territorial structure found by our study.

Dorsal Phalloplasty to Preserve Penis Length after Penile Prosthesis Implantation

Directory of Open Access Journals (Sweden)

Osama Shaeer

2017-03-01

Full Text Available Objectives: Following penile prosthesis implantation (PPI, patients may complain of a decrease in visible penis length. A dorsal phalloplasty defines the penopubic junction by tacking pubic skin to the pubis, revealing the base of the penis. This study aimed to evaluate the efficacy of a dorsal phalloplasty in increasing the visible penis length following PPI. Methods: An inflatable penile prosthesis was implanted in 13 patients with severe erectile dysfunction (ED at the Kamal Shaeer Hospital, Cairo, Egypt, from January 2013 to May 2014. During the surgery, nonabsorbable tacking sutures were used to pin the pubic skin to the pubis through the same penoscrotal incision. Intraoperative penis length was measured before and after the dorsal phalloplasty. Overall patient satisfaction was measured on a 5-point rating scale and patients were requested to subjectively compare their postoperative penis length with memories of their penis length before the onset of ED. Results: Intraoperatively, the dorsal phalloplasty increased the visible length of the erect penis by an average of 25.6%. The average length before and after tacking was 10.2 ± 2.9 cm and 13.7 ± 2.8 cm, respectively (P <0.002. Postoperatively, seven patients (53.8% reported a longer penis, five patients (38.5% reported no change in length and one patient (7.7% reported a slightly shorter penis. The mean overall patient satisfaction score was 4.9 ± 0.3. None of the patients developed postoperative complications. Conclusion: A dorsal phalloplasty during PPI is an effective method of increasing visible penis length, therefore minimising the impression of a shorter penis after implantation.

Full Text Available Agenesis of the dorsal mesentery is a rare occurrence that usually presents in children. It is associated with proximal small bowel malrotation as well as high jejunal atresia with discontinuity of the small bowel. We present a case report of an adolescent presenting with clinical features of proximal small bowel obstruction (confirmed on imaging as well as acute pancreatitis. At laparotomy, he was found to have no dorsal mesentery, without small bowel atresia, and the duodenum was fixed to the posterior abdominal wall. The patient recovered well and remained symptom-free.

CAPABLE TERRITORIAL COMMUNITIES: THE FINANCIAL ASPECT OF FUNCTIONING

2018-03-01

Full Text Available Introduction. The essence of administrative and territorial reform is analyzed in the article. The role of capable territorial communities is substantiated in the integrated development of the local government system. Purpose. The purpose of the article is to substantiate the theoretical and methodological provisions concerning the development and functioning of capable territorial communities as a guarantee of the effective economic development of the local territories. Results. The theoretical and methodological provisions concerning the development and functioning of the capable territorial communities as the basis of effective economic development of local territories are substantiated. The financial opportunities of the united territorial communities in the solving of problems of a local level have been analyzed. Conclusions. Consequently, the sustainable development of the social economic systems depends directly on the management of economic entity, namely, their economic activity under the influence of processes occurring in the political, social and legal spheres of the domestic economic system. Today one of such processes is the decentralization of power and the creation of a new system of state and a local government. The policy of decentralization of power contributes to the improvement of the economic and social situation in the country, the improvement of relations between the state and local levels of power relations and the rational and efficient use of budgetary funds at various levels of government. The main task of the administrative territorial reform that has been analyzed in accordance with the law is the transfer of power to the places in order to concentrate their own and public funds and resources and their spending on their own needs and development. It is a matter of establishing united territorial communities, which are called to carry out the development of adjacent territories to the unions through the adoption of

Enchained territories, migratory displacements and adaptive ruralities

Directory of Open Access Journals (Sweden)

Luis Camarero

2017-05-01

Full Text Available The text is concerned with the ways in which the territories, in this case the different rural areas and localities, are integrated, linked or dissociated into processes and chains of production and economic of a global order. The connection between territories and economic chains occurs through flows of goods, inputs and capital, but also through migratory movements and diverse mobility practices. The process of social division of labor generates new logics of integration / disintegration of the regions in the socioeconomic process, and different mobility demands associated with these changes. The hypothesis that encloses this text is that places and territories will reach to insert in global chains if they develop capacities of adaptability to the productive conditions and especially they manage to reduce the territorial friction guaranteeing the migratory management and mobility of the labor force. With this point of view the socio-agricultural evolution of the rural areas in Spain is contemplated from the end of century XIX

Yelatskov Alexey

2012-01-01

Full Text Available The article examines the notions of ‘territorial political system’ and ‘regional geopolitical system' as well as a correlation between them from the viewpoint of the socalled activity-based geospatial approach. A regional geopolitical system includes geopolitical relations between the states within the region and those with powerful external actors. A geopolitical region itself can be characterized by integration, autonomization or a permanent geopolitical conflict. A territorial political system is studied in a broad sense (all political phenomena of a certain territory and in a narrow context (geopolitical relations of a certain territory. The latter is considered to be a subsystem of regional geopolitical system. The research results can be applied in the study of geopolitical regions and geopolitical systems. The article develops a methodology for regional geopolitical and political geographical studies. The author wishes to thank his colleagues from Saint Petersburg State University for their comments on earlier versions.

The presence of nuclear cactus in the early Drosophila embryo may extend the dynamic range of the dorsal gradient.

Directory of Open Access Journals (Sweden)

Michael D O'Connell

2015-04-01

Full Text Available In a developing embryo, the spatial distribution of a signaling molecule, or a morphogen gradient, has been hypothesized to carry positional information to pattern tissues. Recent measurements of morphogen distribution have allowed us to subject this hypothesis to rigorous physical testing. In the early Drosophila embryo, measurements of the morphogen Dorsal, which is a transcription factor responsible for initiating the earliest zygotic patterns along the dorsal-ventral axis, have revealed a gradient that is too narrow to pattern the entire axis. In this study, we use a mathematical model of Dorsal dynamics, fit to experimental data, to determine the ability of the Dorsal gradient to regulate gene expression across the entire dorsal-ventral axis. We found that two assumptions are required for the model to match experimental data in both Dorsal distribution and gene expression patterns. First, we assume that Cactus, an inhibitor that binds to Dorsal and prevents it from entering the nuclei, must itself be present in the nuclei. And second, we assume that fluorescence measurements of Dorsal reflect both free Dorsal and Cactus-bound Dorsal. Our model explains the dynamic behavior of the Dorsal gradient at lateral and dorsal positions of the embryo, the ability of Dorsal to regulate gene expression across the entire dorsal-ventral axis, and the robustness of gene expression to stochastic effects. Our results have a general implication for interpreting fluorescence-based measurements of signaling molecules.

Role of the right dorsal anterior insula in the urge to tic in Tourette syndrome.

The mid-posterior part of the insula is involved in processing bodily sensations and urges and is activated during tic generation in Tourette syndrome. The dorsal anterior part of the insula, however, integrates sensory and emotional information with cognitive valuation and is implicated in interoception. The right dorsal anterior insula also participates in urge suppression in healthy subjects. This study examined the role of the right dorsal anterior insula in the urge to tic in Tourette syndrome. Resting-state functional magnetic resonance imaging was performed in 13 adult Tourette patients and 13 matched controls. The role of the right dorsal anterior insula within the urge-tic network was investigated using graph theory-based neural network analysis. The functional connectivity of the right dorsal anterior insula was also correlated with urge and tic severity. Even though the patients did not exhibit any overt tics, the right dorsal anterior insula demonstrated higher connectivity, especially with the frontostriatal nodes of the urge-tic network in patients compared with controls. The functional connectivity between the right dorsal anterior insula and bilateral supplementary motor area also correlated positively with urge severity in patients. These results suggest that the right dorsal anterior insula is part of the urge-tic network and could influence the urge- and tic-related cortico-striato-thalamic regions even during rest in Tourette syndrome. It might be responsible for heightened awareness of bodily sensations generating premonitory urges in Tourette syndrome. © 2015 International Parkinson and Movement Disorder Society.

The dorsal striatum plays a key role in the learning and expression of instrumental reward associations that are acquired through direct experience. However, not all learning about instrumental actions require direct experience. Instead, humans and other animals are also capable of acquiring instrumental actions by observing the experiences of others. In this study, we investigated the extent to which human dorsal striatum is involved in observational as well as experiential instrumental reward learning. Human participants were scanned with fMRI while they observed a confederate over a live video performing an instrumental conditioning task to obtain liquid juice rewards. Participants also performed a similar instrumental task for their own rewards. Using a computational model-based analysis, we found reward prediction errors in the dorsal striatum not only during the experiential learning condition but also during observational learning. These results suggest a key role for the dorsal striatum in learning instrumental associations, even when those associations are acquired purely by observing others.

Campania: Territory and City in front of the Challenge of Logistics

Full Text Available Logistics can be defined as the process of planning, organization and control of all the activities of transportand storage of goods and informations; it interests all the productive phases, from the acquisition of rawmaterials, to the production process in the factories, up to the delivery of the finished products to the finalcustomers. In this way the logistics intersects the territory at different stages of its activity: when the rawmaterials are brought to the factory, when the factory sends semi-production units to other factories, whereproducts are stored in equipped areas, and when the final goods are brought to terminal sales.Inside the Southern territorial system the Campania is an important hub in the transport and sorting ofgoods. This role has made stronger after the carrying out of new logistics infrastructures, related to othersupport infrastructures, as railways and motorways.The regional system presents nationwide excellence’s peaks that could encourage its role in this sector, butthere are also negative factors that may to slow the take-off of the sector. The reference is to theinfrastructures and operating bottlenecks interfering its efficiency, but also to the weakness of the regionalproduction’s system that doesn’t ensures a local critical mass to the logistics.A third aspect is the lack of a clear structure of programming investment and of a greater transparency inthe roles assigned to various initiatives, arising mainly on local, uncoordinated pushes.The paper analyzes the situation of logistics and of its spatial interrelationships in Campania, identifyingstrengths, weaknesses, and potential evolutionary factors. The discussion faces up aspects of territoriallogistics: it differs from the urban logistics for the amount of handled commodities and for the concentrationin strategic poles, because these logistics platforms require specialized equipments and wide spaces formovement and deposit.The first part of the paper

How neural specificity for distinct conceptual knowledge categories arises is central for understanding the organization of semantic memory in the human brain. Although there is a large body of research on the neural processing of distinct object categories, the organization of action categories remains largely unknown. In particular, it is unknown whether different action categories follow a specific topographical organization on the cortical surface analogously to the category-specific organization of object knowledge. Here, we tested whether the neural representation of action knowledge is organized in terms of nonsocial versus social and object-unrelated versus object-related actions (sociality and transitivity, respectively, hereafter). We hypothesized a major distinction of sociality and transitivity along dorsal and ventral lateral occipitotemporal cortex (LOTC), respectively. Using fMRI-based multivoxel pattern analysis, we identified neural representations of action information associated with sociality and transitivity in bilateral LOTC. Representational similarity analysis revealed a dissociation between dorsal and ventral LOTC. We found that action representations in dorsal LOTC are segregated along features of sociality, whereas action representations in ventral LOTC are segregated along features of transitivity. In addition, representations of sociality and transitivity features were found more anteriorly in LOTC than representations of specific subtypes of actions, suggesting a posterior-anterior gradient from concrete to abstract action features. These findings elucidate how the neural representations of perceptually and conceptually diverse actions are organized in distinct subsystems in the LOTC. The lateral occipitotemporal cortex (LOTC) is critically involved in the recognition of objects and actions, but our knowledge about the underlying organizing principles is limited. Here, we discovered a dorsal-ventral distinction of actions in LOTC

Excessive ultraviolet radiation (UVR) exposure is the primary predisposing factor for basal cell carcinoma (BCC). However, surprisingly, BCCs occur very rarely on the dorsal hand, which is subject to intense sun exposure, and their infrequent presentation in this location suggests that other factors besides UVR may play a role in BCC pathogenesis. Because dorsal hand BCCs are uncommon, knowledge of their characteristics is limited, and more data are needed to describe their clinical presentation and treatment. To perform an updated review of the literature on the management of dorsal hand BCCs. The authors conducted a comprehensive literature review by searching the PubMed database with the key phrases "basal cell carcinoma dorsal hand," "basal cell carcinoma hand," and "basal cell carcinoma finger," and "basal cell carcinoma thumb." The authors identified 176 cases of dorsal hand BCCs in the literature, 120 of which had sufficient data for analysis. Only 4 cases were treated with Mohs micrographic surgery (MMS). The authors present 14 additional cases of dorsal hand BCCs treated with MMS. Basal cell carcinomas on the dorsal hand occur infrequently, and potential risk factors include being a male of white descent and personal history of skin cancer. Mohs micrographic surgery seems to be an effective treatment method.

Ultraviolet radiation is a well-known risk factor for basal cell carcinoma (BCC). Therefore, the high incidence of BCCs in sun-exposed areas such as the head and neck is unsurprising. However, unexpectedly, BCCs on the sun-protected dorsal foot have also been reported, and tumor occurrence here suggests that other factors besides ultraviolet radiation may play a role in BCC pathogenesis. Because only few dorsal foot BCCs have been reported, data on their clinical features and management are limited. To perform an updated review of the literature on clinical characteristics and treatment of dorsal foot BCCs. We conducted a comprehensive literature review by searching the PubMed database with the key phrases "basal cell carcinoma dorsal foot," "basal cell carcinoma foot," and "basal cell carcinoma toe." We identified 20 cases of dorsal foot BCCs in the literature, 17 of which had sufficient data for analysis. Only 1 case was treated with Mohs micrographic surgery. We present 8 additional cases of dorsal foot BCCs treated with Mohs micrographic surgery. Basal cell carcinomas on the dorsal foot are rare, and potential risk factors include Caucasian descent and personal history of skin cancer. Mohs micrographic surgery seems to be an effective treatment option.

Association, property, territory: What is at stake in immigration?

Directory of Open Access Journals (Sweden)

Miklósi Zoltán

2017-01-01

Full Text Available It is often claimed that states have territorial rights, and that these rights include the right to exclude people who seek admission to their territory. In this paper I will examine whether the most defensible account of territorial rights can provide support to the right to exclude. I will discuss three types of theories of territorial rights. The first account links the right of states to exclude to the prior right of individuals to freedom of association, which is said to include the right not to associate and to dissociate. The second is a Lockean theory that grounds the territorial rights of states, and hence their right to exclude, in the prior right of individuals to private property in the land that constitutes the territory of the state. I argue that these accounts have independently implausible implications, regardless of their implications for the immigration debate. The third account is a Kantian theory that bases the territorial jurisdiction of states on individuals’ duty to create, sustain and submit themselves to a shared system of law that is a necessary condition of guaranteeing their rights and of discharging their duties towards one another. I will argue that the Kantian account is superior to its current alternatives. However, I also suggest that it cannot ground a broad right to exclude.

. Using the instruments of municipal marketing social-ethic conception one can focus target audiences’ attention on social, ecological and economical territorial attractiveness ensuring stable territorial development. Territorial marketing within the framework of partnership conceptions as the philosophy of territorial (region, city functioning based on the formation, support and development of mutually beneficial long-term relations between the participants of interaction will create new common values, obtaining and sharing advantages of this activity. The development of the relations between territory and its target audiences defines and forms the basis of the environment to make decisions as to the habitation, visiting, conducting business, investment etc., i. e. forms specific territory’s (country, region, city, settlement attractiveness. Novelty. On the basis of this research the authors proposed to consider marketing approach to territorial (regional, urban attractiveness as a transition to long-term development in the field of systematic management on the basis of consumers’ demands orientation and partnership, clear definition of target audience and its demands, flexible regional policy, applying both traditional and non-traditional instruments to form, improve, support and, sometimes, decrease the attractiveness of territory with demarketing means. Conclusions. It has been determined, that according to marketing approach, the attractiveness of the territory is – the ideas total about properties and features, factors and conditions, limits and possibilities, means and instruments, providing satisfaction and the perspective of increase of target audiences’ needs while they choose a proper region for activity and organize their loyalty towards the territory (region, city. Marketing policy of the attractiveness of territories is proposed as a complex of measures aimed at attracting target audience’s attention, it’s being worked out and realized by

The evolution of the dorsal thalamus of jawed vertebrates, including mammals: cladistic analysis and a new hypothesis.

Science.gov (United States)

Butler, A B

1994-01-01

The evolution of the dorsal thalamus in various vertebrate lineages of jawed vertebrates has been an enigma, partly due to two prevalent misconceptions: the belief that the multitude of nuclei in the dorsal thalamus of mammals could be meaningfully compared neither with the relatively few nuclei in the dorsal thalamus of anamniotes nor with the intermediate number of dorsal thalamic nuclei of other amniotes and a definition of the dorsal thalamus that too narrowly focused on the features of the dorsal thalamus of mammals. The cladistic analysis carried out here allows us to recognize which features are plesiomorphic and which apomorphic for the dorsal thalamus of jawed vertebrates and to then reconstruct the major changes that have occurred in the dorsal thalamus over evolution. Embryological data examined in the context of Von Baerian theory (embryos of later-descendant species resemble the embryos of earlier-descendant species to the point of their divergence) supports a new 'Dual Elaboration Hypothesis' of dorsal thalamic evolution generated from this cladistic analysis. From the morphotype for an early stage in the embryological development of the dorsal thalamus of jawed vertebrates, the divergent, sequential stages of the development of the dorsal thalamus are derived for each major radiation and compared. The new hypothesis holds that the dorsal thalamus comprises two basic divisions--the collothalamus and the lemnothalamus--that receive their predominant input from the midbrain roof and (plesiomorphically) from lemniscal pathways, including the optic tract, respectively. Where present, the collothalamic, midbrain-sensory relay nuclei are homologous to each other in all vertebrate radiations as discrete nuclei. Within the lemnothalamus, the dorsal lateral geniculate nucleus of mammals and the dorsal lateral optic nucleus of non-synapsid amniotes (diapsid reptiles, birds and turtles) are homologous as discrete nuclei; most or all of the ventral nuclear group

Full Text Available The purpose of the paper is to study the essence of agent-based modeling, defining its features and prospects of usage in the modeling of socio-economic development of territories and systematization of domestic and foreign approaches to the development of prototypes for agent-based models of territories. Information basis for the research comprised the works on agent-based modeling by Russian and foreign scholars, especially articles and monographs of scientists of the Central Economics and Mathematics Institute under the Russian Academy of Sciences, papers presented in an international journal The Journal of Artificial Societies and Social Simulation and other sources available on the Internet. The article presents theoretical and methodological foundations of agent-based models of territories. The author considers the concepts of “agent-based modeling” and “agent” and defines specifics of agent-based models in comparison with other types of simulation modeling. The paper also describes major stages of building agent-based models for territories and considers qualification requirements to a modeling subject. Furthermore, it reviews Russian and foreign approaches to the development of prototypes for agent-based models of territories. It has been determined that most of them deal with the modeling of spatial, territorial and socio-economic development of regions, cities and municipal entities. Agents in such models are presented by households, residents of regions and cities, enterprises and organizations operating in their territory, and public administration authorities (their inclusion in the model makes it possible to test different options of management impacts on territories by changing the model parameters, for instance, the introduction of certain prohibitions and quotas, issuance of permits, distribution of financial resources, etc.. At the end of the paper, the author formulates major conclusions. He shows the complexity faced

The sodium-activated potassium channel Slack (Kcnt1, Slo2.2) is highly expressed in dorsal root ganglion neurons where it regulates neuronal firing. Several studies have implicated the Slack channel in pain processing, but the precise mechanism or the levels within the sensory pathway where channels are involved remain unclear. Here, we furthered the behavioral characterization of Slack channel knockout mice and for the first time examined the role of Slack channels in the superficial, pain-processing lamina of the dorsal horn. We performed whole-cell recordings from spinal cord slices to examine the intrinsic and synaptic properties of putative inhibitory and excitatory lamina II interneurons. Slack channel deletion altered intrinsic properties and synaptic drive to favor an overall enhanced excitatory tone. We measured the amplitudes and paired pulse ratio of paired excitatory post-synaptic currents at primary afferent synapses evoked by electrical stimulation of the dorsal root entry zone. We found a substantial decrease in the paired pulse ratio at synapses in Slack deleted neurons compared to wildtype, indicating increased presynaptic release from primary afferents. Corroborating these data, plantar test showed Slack knockout mice have an enhanced nociceptive responsiveness to localized thermal stimuli compared to wildtype mice. Our findings suggest that Slack channels regulate synaptic transmission within the spinal cord dorsal horn and by doing so establishes the threshold for thermal nociception.

Industrial ecology and sustainable development share the concept of territory. Two models of territorial development are proposed: Eco industrial Parks and Italian Districts. Both models use industrial-ecology concepts and strategies, but both are still far from incorporating sustainability. This ideal could be pursed by more and better networking, in the first case to strengthen links with the local community, and in the second to increase financial resources. The Masurin project, co-funded by the EU, provides a response to this lack. This article describes Batter (one of the Masurin tolls) and its application to the city of Venice) [it

Altenritter, Matthew E.; Kinnison, Michael T.; Zydlewski, Gayle B.; Secor, David H.; Zydlewski, Joseph D.

2015-01-01

The imperiled status of sturgeons worldwide places priority on the identification and protection of critical habitats. We assessed the micro-structural and micro-chemical scope for a novel calcified structure, dorsal scutes, to be used for reconstruction of past habitat use and group separation in shortnose sturgeon (Acipenser brevirostrum). Dorsal scutes contained a dual-layered structure composed of a thin multi-layered translucent zone lying dorsally above a thicker multi-layered zone. Banding in the thick multi-layered zone correlated strongly with pectoral fin spine annuli supporting the presence of chronological structuring that could contain a chemical record of past environmental exposure. Trace element profiles (Sr:Ca), collected using both wavelength dispersive electron microprobe analysis and laser ablation inductively coupled mass spectrometry, suggest scutes record elemental information useful for tracing transitions between freshwater and marine environments. Moreover, mirror-image like Sr:Ca profiles were observed across the dual-zone structuring of the scute that may indicate duplication of the microchemical profile in a single structure. Additional element:calcium ratios measured in natal regions of dorsal scutes (Ba:Ca, Mg:Ca) suggest the potential for further refinement of techniques for identification of river systems of natal origin. In combination, our results provide proof of concept that dorsal scutes possess the necessary properties to be used as structures for reconstructions of past habitat use in sturgeons. Importantly, scutes may be collected non-lethally and with less injury than current structures, like otoliths and fin spines, affording an opportunity for broader application of microchemical techniques.

Full Text Available The article promotes an approach to assess the prospects of regional development on the basis of the synthesis of comparative and historical methods of research. According to the authors, the comparative analysis of the similar functioning of the socio-economic systems forms deeper understanding what part factors and methods of state regulation play in regional development, and also their place in socio-economic and geopolitical space. The object of the research is Kamchatka territory as the region playing strategically important role in socio-economic development of Russia and also northern territories of the other countries comparable with Kamchatka on the bass if environmental conditions such as Iceland, Greenland, USA (Alaska, Canada (Yukon, and Japan (Hokkaido. On the basis of allocation of the general signs of regional socio-economic systems and creation of the regional development models forming the basis for comparative estimates, the article analyses the territories, which are comparable on the base of climatic, geographic, economic, geopolitical conditions, but thus significantly different due to the level of economic familiarity. The generalization of the extensive statistical material characterizing various spheres of activity at these territories, including branch structure of the economy, its infrastructure security, demographic situation, the budgetary and financial sphere are given. It allows defining the crucial features of the regional economy development models. In the conclusion, the authors emphasize that ignoring of the essential relations among the regional system elements and internal and external factors deprives a research of historical and socio-economic basis.

We report the case of disseminated metastatic tumor at dorsal surface of medulla oblongata presenting intractable hiccups. A 73-year-old man has a history of for metastatic lung tumor of the left tempral lobe. Although 3 surgeries and 4 radiotherapies were performed in the last 8 years, residual tumor grew slowly. He presented with intractable hiccups. His hiccups continued for 30 minutes, sometimes for 3 hours with obstruction of eating. Contrast-enhanced Magnetic resonance (MR) imaging demonstrated the dissemination of metastatic lung tumor at dorsal surface of medulla oblongata and ventral surface of midbrain. Some literatures reported the patients with intractable hiccups caused by dorsal medullary lesions. Therefore, we thought that the small disseminated tumor at dorsal surface of medulla oblongata caused the hiccups. Evaluation of dorsal medullay area by MR imaging is important to reveal the cause of intractable hiccups.

2001-03-01

A cytoarchitectonic analysis of the telencephalon of the sea bass Dicentrarchus labrax, based on cresyl violet-stained serial transverse sections, is presented. Rostrally, the brain of the sea bass is occupied by sessile olfactory bulbs coupled to telencephalic hemispheres. The olfactory bulbs comprise an olfactory nerve fiber layer, a glomerular layer, an external cellular layer, a secondary olfactory fiber layer, and an internal cellular layer. Large terminal nerve ganglion cells are evident in the caudomedial olfactory bulbs. We recognized 22 distinct telencephalic nuclei which were classified in two main areas, the ventral telencephalon and the dorsal telencephalon. The ventral telencephalon displays four periventricular cell masses: the dorsal, ventral, supracommissural, and postcommissural nuclei; and four migrated populations: the lateral, central, intermediate, and entopeduncular nuclei. In addition, a periventricular cell population resembling the lateral septal organ reported in birds is observed in the ventral telencephalon of the sea bass. The dorsal telencephalon contains 13 nuclei, which can be organized into five major zones: the medial part, dorsal part, lateral part and its ventral, dorsal, and posterior divisions, the central part, and posterior part. Based on histological criteria, two cell masses are recognized in the ventral division of the lateral part of the dorsal telencephalon. The nucleus taenia is found in the caudal area of the dorsal telencephalon, close to the ventral area. This study represents a useful tool for the precise localization of the neuroendocrine territories and for the tracing of the neuronal systems participating in the regulation of reproduction and metabolism in this species.

Responses of spinal dorsal horn neurons to foot movements in rats with a sprained ankle

Science.gov (United States)

Kim, Jae Hyo; Kim, Hee Young; Chung, Kyungsoon

2011-01-01

Acute ankle injuries are common problems and often lead to persistent pain. To investigate the underlying mechanism of ankle sprain pain, the response properties of spinal dorsal horn neurons were examined after ankle sprain. Acute ankle sprain was induced manually by overextending the ankle of a rat hindlimb in a direction of plantarflexion and inversion. The weight-bearing ratio (WBR) of the affected foot was used as an indicator of pain. Single unit activities of dorsal horn neurons in response to plantarflexion and inversion of the foot or ankle compression were recorded from the medial part of the deep dorsal horn, laminae IV-VI, in normal and ankle-sprained rats. One day after ankle sprain, rats showed significantly reduced WBRs on the affected foot, and this reduction was partially restored by systemic morphine. The majority of deep dorsal horn neurons responded to a single ankle stimulus modality. After ankle sprain, the mean evoked response rates were significantly increased, and afterdischarges were developed in recorded dorsal horn neurons. The ankle sprain-induced enhanced evoked responses were significantly reduced by morphine, which was reversed by naltrexone. The data indicate that movement-specific dorsal horn neuron responses were enhanced after ankle sprain in a morphine-dependent manner, thus suggesting that hyperactivity of dorsal horn neurons is an underlying mechanism of pain after ankle sprain.

2012-03-01

Full Text Available In this paper we focus on the structure and territorial borders of the Baltic Sea region, and examine the key structural elements of the transnational territorial transport system. In this respect, we clarify some terms used in transport geography. For the first time the transport system gets territorially localized, which allows for a broad range of new studies of transnational transportation in the Baltic Sea area. We also identify the main principles of development and operation of international territorial transport systems and present them taking the Baltic Sea region as an example. Our findings, we hope, will have a great practical application for researchers of transport geography, especially those studying international logistics.

Directory of Open Access Journals (Sweden)

Manmeet Singh

2013-01-01

Full Text Available Introduction: Female urethral stricture is an underdiagnosed and overlooked cause of female bladder outlet obstruction. The possible etiologies may be infection, prior dilation, difficult catheterization with subsequent fibrosis, urethral surgery, trauma, or idiopathic. We present our technique and results of dorsal onlay full thickness vaginal graft urethroplasty for female urethral stricture. Materials and Methods: A retrospective review was performed on 16 female patients with mid-urethral stricture who underwent dorsal onlay vaginal graft urethroplasty from January 2007 to June 2011.Of these, 13 patients had previously undergone multiple Hegar dilatations, three had previous internal urethrotomies. The preoperative work up included detailed voiding history, local examination, uroflowmetry, calibration, and micturating cystourethrogram. Results: All patients had mid-urethral stricture. Mean age was 47.5 years. Mean Q max improved from 6.2 to 27.6 ml/s. Mean residual volume decreased from 160 to 20 ml. Mean duration of follow-up was 24.5 months (6 months to 3 years. Only one patient required self-calibration for 6 months after which her stricture stabilized. None of the patient was incontinent. Conclusion: Dorsal vaginal onlay graft urethroplasty could be considered as an effective way to treat female urethral stricture.

ZAIATS Yi. I.

2015-11-01

Full Text Available Problem statement. For planning and organization of urban construction is necessary to analyze the use of areas. Territorial resources of the city, being used for construction and other urban purposes, consists of plots of land: disposable, reserved and undeveloped in previous years of construction in progress; residential districts and blocks of obsolete housing fund; industrial and municipal and warehouse enterprises being used irrationally or stopped to work; the defence department, where the amortized warehouses and other main funds are that are not used by purpose; agricultural enterprises where the obsolete industrial funds, haying, nurseries, greenhouses. The number of free areas suitable for future urban development is extremely limited. However a considerable part of the territories of almost all functional zones is used inefficiently. Purpose. Formalization of a factor of investment attractiveness of territories for the further identification and research of the connection between it and the cost of housing construction is necessary. Conclusion. The identification of regularities of influence of the factor of investment attractiveness of territories on the cost of construction of high-rise buildings allow to obtain a quantitative estimate of this effect and can be used in the development of the methodology of substantiation of the expediency and effectiveness of the implementation of highrise construction projects, based on organizational and technological aspects.

Manuel Chiriboga

2013-09-01

Full Text Available This article draws from the preliminary findings of an ongoing appliedresearch program on rural territorial dynamics carried out by the Latin American Center for Rural Development (RIMISP. The article provides some initial findings on 4 territories, of the 11 territories that are part of the overall study. The case studies include the island of Chiloé in southern Chile, the province of Tungurahua in Ecuador, a dairy farm region of Santo Tomás Nicaragua and Cuatro Lagunas near Cuzco Perú. Rural areas in Latin America are characterized by their dual nature with agro-exporting enclaves linked to global value chains alongside impoverished peasant economies, leading to differentiated policy recommendations. The research attempts to find relationships between reduced poverty and inequality in winning regions, measured by three variables, with issues of access to resources, human capital, political empowerment, markets and institutions, with particular attention to innovative social coalitions.

Indigenous Territories and REDD in Latin America: Opportunity or Threat?

Directory of Open Access Journals (Sweden)

Chris van Dam

2011-03-01

Full Text Available An important proportion of Latin America’s forests are located in indigenous territories, and indigenous peoples are the beneficiaries of about 85% of the area for which local rights to land and forest have been recognized in Latin America since the 1980s. Nevertheless, many of these areas, whether or not rights have been recognized, are subject to threats from colonists, illegal loggers, mining and oil interests and others, whose practices endanger not only the forests but also indigenous people’s territory as a whole. In this context, REDD could constitute a new threat or intensify others, particularly in places where indigenous tenure rights have not been recognized, but REDD could also offer new opportunities. This article describes the limitations of thinking only in terms of communities, rather than territories, and examines the extent to which REDD has been conceived considering the characteristics of this new territorial configuration. It also identifies the challenges that REDD may face with this new ‘stakeholder’, such as numerous specific characteristics of territories, given their heterogeneity, in the context of past experiences regarding ‘forest options’. This paper analyses the situation in already-titled indigenous territories in particular, and also discusses problems facing territories in the titling process.

Non-adaptive territory selection by a bird with exceptionally long parental care

Directory of Open Access Journals (Sweden)

Radosław Włodarczyk

2016-03-01

Full Text Available High-quality territories are expected to provide greater fitness return for breeding individuals and, thus, are likely to have higher long-term occupation rate in comparison to low-quality territories. However, if environmental and ecological cues used for territory selection cannot reliably predict true territory quality, a mismatch between preferences and fitness may occur. We suggest that this kind of non-adaptive territory selection is more likely in species with long reproductive cycles, as a long time interval between territory establishment and young fledgling should reduce predictability of conditions during the critical stages of brood care. In this study, we investigated adaptiveness of territory selection in a migratory bird with exceptionally long parental care, the mute swan Cygnus olor, which requires over four months to complete the entire reproductive cycle from egg laying to young fledging. For this purpose, we collected information on the long-term (10–19 years occupancy of 222 swan breeding territories and correlated it with reproductive performance (n = 1,345 breeding attempts and body condition of breeding adults. We found that long-term occupancy positively correlated with the timing of breeding, suggesting that individuals settled earlier in the attractive, frequently occupied territories. By contrast, we found no relationship between territory occupancy and reproductive output (hatching and fledging success or adult body condition. The results indicate that at the time of territory selection swans might not be able to reliably assess territory quality, likely due to: (1 exceptionally long period of parental care, which reduces temporal correlation between the conditions at the time of territory selection and conditions during chick rearing; and (2 unpredictability of human-related activities that had a major impact on reproductive output of swan pairs in our population.

Moysés, Simone Tetu; Franco de Sá, Ronice

2014-11-01

The article highlights the importance of considering the specificities of spaces/territories/ locations of individual and collective life in creating health promotion actions. It explores how this approach has conceptually consolidated respect for territoriality and territorial actions as a principle and an operational health promotion strategy. Based on the literature, the article also points to the need to envision the territory occupied as a locus to put intersetorialities into practice, giving a voice to people who live there, seek to and solve their complex problems, to existing and emerging social networks. It also presents a nationally and internationally validated strategy/method (Bamboo Method) for the development of local health promotion plans, which enables the prioritization of actions by listening to the people and to the managers.

Territorial Dynamics and Gender Equality Policies in Spain

Directory of Open Access Journals (Sweden)

Alba Alonso

2014-12-01

Full Text Available This article analyses the impact of the multilevel governance structure in Spain. Particularly, it explores how the main territorial dynamics underpinning the Spanish decentralization model have shaped gender equality policies, namely the cross-regional competitive bargaining, the existence of multiple arenas, the underdevelopment of intergovernmental mechanisms and a highly salient territorial cleavage. The article looks at three key fields of gender equality public intervention and scholarly research: gender mainstreaming, electoral gender quotas and policies against gender-based violence. Our results align with the conditional approach of the gender and federalism scholarship. While competition has stimulated policy diffusion across regions and feminist agency has frequently benefited from the multilevel opportunity structure, the lack of well-established intergovernmental mechanisms has brought about negative side-effects like ‘patchwork’ policies that fail to guarantee equal rights for all Spanish women. The article also shows that territorial interests have not trumped gender equality since the most advanced policies are found in regions with the highest territorial saliency.

We propose that Kasai's classification is appropriate for guiding treatment.

Dorsal stream involvement in recognition of objects with transient onset but not with ramped onset

Directory of Open Access Journals (Sweden)

Lourenco Tomas

2011-08-01

Full Text Available Abstract Background Although the ventral visual stream is understood to be responsible for object recognition, it has been proposed that the dorsal stream may contribute to object recognition by rapidly activating parietal attention mechanisms, prior to ventral stream object processing. Methods To investigate the relative contribution of the dorsal visual stream to object recognition a group of tertiary students were divided into good and poor motion coherence groups and assessed on tasks classically assumed to rely on ventral stream processing. Participants were required to identify simple line drawings in two tasks, one where objects were presented abruptly for 50 ms followed by a white-noise mask, the other where contrast was linearly ramped on and off over 325 ms and replaced with a mask. Results Although both groups only differed in motion coherence performance (a dorsal stream measure, the good motion coherence group showed superior contrast sensitivity for object recognition on the abrupt, but not the ramped presentation tasks. Conclusions We propose that abrupt presentation of objects activated attention mechanisms fed by the dorsal stream, whereas the ramped presentation had reduced transience and thus did not activate dorsal attention mechanisms as well. The results suggest that rapid dorsal stream activation may be required to assist with ventral stream object processing.

Two middle-aged-patients each presenting with a progressively enlarging mass in the first dorsal web space of their hands are reported. Magnetic resonance imaging (MRI) demonstrated the cause to be a hypertrophic first dorsal inter osseous muscle, with normal T1, T2 and post-gadopentetate dimeglumine signal characteristics. The ability of MRI to diagnose anatomical variants of hand muscles is important in the clinical management of patients with these pseudotumours. The usefulness of magnetic resonance imaging (MRI) in evaluation of soft tissue tumours of the musculoskeletal system is now widely accepted. Its ability to maximize contrast between tumour and adjacent normal tissue in a multiplanar manner makes it the imaging modality of choice in pre-operative staging of soft tissue masses. In the hand and wrist, where benign tumours predominate, MRI may provide a specific diagnosis. We describe two cases in which MRI demonstrated the cause of a hand pseudotumour to be due to hypertrophy of the first dorsal inter osseous muscle. Copyright (1999) Blackwell Science Pty Ltd

After having outlined that each territory does not possess the same potential in terms of energy efficiency, a first issue of this publication outlines the role of territorial planning to improve performance and efficiency of the built environment, to develop infrastructures and to improve their quality, to organise mobility demand, to put back the car to a right place, to reduce and to optimise goods road transport. It also notices that planning is not enough: individuals must somehow be constrained and encouraged, and changes of practices on the long term must be promoted. A panel of solutions to be adapted to the local context is then proposed for different situations related to mobility and transport. The second issue first outlines how to valorise local energy potentials by promoting energy saving and energy efficiency, by choosing the right energy for the right usage. It shows how to promote interdependency and solidarity between territories as far as energy production and consumption are concerned. It describes how to plan renewable energy sites in town planning documents

Normally, the ophthalmic artery (OA) arises from the supraclinoid segment of the internal carotid artery (ICA) and enters the orbit via the optic canal. A persistent dorsal OA is a rare variation that originates from the cavernous segment of the ICA and enters the orbit via the superior orbital fissure. To the best of our knowledge, persistent dorsal OA has not been described in the Korean literature. In this paper, we report three cases of persistent dorsal OA with review of the literature on embryogenesis and other origins of the OA.

Investigating category- and shape-selective neural processing in ventral and dorsal visual stream under interocular suppression.

Science.gov (United States)

Ludwig, Karin; Kathmann, Norbert; Sterzer, Philipp; Hesselmann, Guido

2015-01-01

Recent behavioral and neuroimaging studies using continuous flash suppression (CFS) have suggested that action-related processing in the dorsal visual stream might be independent of perceptual awareness, in line with the "vision-for-perception" versus "vision-for-action" distinction of the influential dual-stream theory. It remains controversial if evidence suggesting exclusive dorsal stream processing of tool stimuli under CFS can be explained by their elongated shape alone or by action-relevant category representations in dorsal visual cortex. To approach this question, we investigated category- and shape-selective functional magnetic resonance imaging-blood-oxygen level-dependent responses in both visual streams using images of faces and tools. Multivariate pattern analysis showed enhanced decoding of elongated relative to non-elongated tools, both in the ventral and dorsal visual stream. The second aim of our study was to investigate whether the depth of interocular suppression might differentially affect processing in dorsal and ventral areas. However, parametric modulation of suppression depth by varying the CFS mask contrast did not yield any evidence for differential modulation of category-selective activity. Together, our data provide evidence for shape-selective processing under CFS in both dorsal and ventral stream areas and, therefore, do not support the notion that dorsal "vision-for-action" processing is exclusively preserved under interocular suppression. © 2014 Wiley Periodicals, Inc.

Sustainability and the Viable Systems Approach: Opportunities and Issues for the Governance of the Territory

Directory of Open Access Journals (Sweden)

Sergio Barile

2018-03-01

Full Text Available The aim of this paper is to propose an approach for representing the territory as a dynamic system of intersubjective relationships that is able to guarantee not only the efficiency of the processes within organizations, but also effective results in the general context and a sustainable impact on the broader environment. This contribution is developed on the basis of the viable systems approach (vSa, which is intended as a theoretical framework for the analysis of social phenomena as well as for orienting government processes. Using this theoretical framework, the proposed approach leads to the representation of the territory as a viable system that is capable of surviving in its own context by creating value for the other entities of the context (public groups of governments, communities, investors, natural environment, future generations, non-human species, thus defining the essential conditions for a sustainable equilibrium. The consideration that social phenomena have to be analyzed by taking into account the different relations and interactions that orient the behavior of individuals and, as a consequence, their main collective manifestations, i.e., organizations, underlines the importance of shifting from a traditional reductionist approach to a systemic approach. In what follows, taking a cue from the definition of sustainability that implies a wider sharing, we provide some initial critical positions, and finally shape the useful elements that can be preparatory to the introduction of a working hypothesis that is capable of delineating a possible itinerary for the development of the territory.

development of agribusiness. The main tasks of the agricultural production of enterprises should be as follows: the correction of specialization and location of livestock production in view of the natural resource base of the landscape; the increase in the share of green fodders from pastures and hayfields; the use of farming technologies adaptive to the climatic conditions that enhance the productivity of agricultural lands and efficiency of the spent material and technical resources; the conservation of degraded agricultural lands followed by grassing, etc. [4–6]. Such an approach will, on the one hand, prevent the manifestation of the adverse natural processes, and, on the other, ensure the environmental sustainability of the territory and the dynamic development of agribusiness, the economic competitiveness of the Russian market and the possibility of import substitution [7]. The aim of the “pilot” draft is to create land tenure with optimal structure and balance. Therefore, agro-ecological evaluation of «Dubovskiy» potential is done to take proper measures to optimize territorial organization of land tenure. The formation of land tenure model will trigger similar actions in 26 districts of Stavropol territory.

Barbagli Guido

2003-01-01

Full Text Available INTRODUCTION: The use of flaps or grafts is mandatory in patients with longer and complex strictures. In 1995-96 we described a new dorsal onlay graft urethroplasty. Over time, our original technique was better defined and changed. Now this procedure (also named Barbagli technique has been greeted with a fair amount of enthusiasm in Europe and in the United States. SURGICAL TECHNIQUE: The patient is placed in normal lithotomy position, and a midline perineo-scrotal incision is made. The bulbar urethra is then free from the bulbo-cavernous muscles, and is dissected from the corpora cavernosa. The urethra is completely mobilized from the corpora cavernosa, it is rotated 180 degrees, and is incised along its dorsal surface. The graft (preputial skin or buccal mucosa or the flap is fixed and quilted to the tunica albuginea of the corporal bodies. The right mucosal margin of the opened urethra is sutured to the right side of the patch-graft. The urethra is rotated back into its original position. The left urethral margin is sutured to the left side of the patch graft and to the corporal bodies, and the grafted area is entirely covered by the urethral plate. The bulbo-cavernous muscles are approximated over the grafted area. A 16F silicone Foley catheter is left in place. COMMENTS: Dorsal onlay graft urethroplasty is a versatile procedure that may be combined with various substitute materials like preputial skin, buccal mucosa grafts or pedicled flaps.

Multidimensional and multiscalar analisis of territorial rural development in Brazil

2013-09-01

Full Text Available Of late, there have been several political, practical and analytical changes to our understanding of rural development. Diverse efforts have emerged in the analysis and discussion of spatial dynamics such as “rurality”, territories, in the construction of a territorial perspective of rural development. These changes in the forms of identification and measurement of rural development lead us to question the validity and effectiveness of applied methods, inviting us to establish methodologies and analytical criteria coherent with the multiple manifestations and scales of development. This article offers a multidimensional and multi-scalar analytical model for territorial rural development, using our methodology tested in four rural territories of Brazil.

The dorsal striatum and ventral striatum play different roles in the programming of social behaviour: a tribute to Lex Cools.

Science.gov (United States)

van den Bos, Ruud

2015-02-01

Early work by Lex Cools suggested that the caudate nucleus (dorsal striatum) plays a role in programming social behaviour: enhanced activity in the caudate nucleus increased the extent to which ongoing behaviour is controlled by the individual's own behaviour (internal control) rather than by that of its partners (external control). Interestingly, later studies by others have indicated that the ventral striatum plays a role in external rather than internal control. Here, I discuss the role of these different striatal areas - and the emotional (ventral striatum) and cognitive control (dorsal striatum) system in which they are embedded - in the organization of social behaviour in the context of locus of control. Following on from this discussion, I will pay particular attention to individual differences in social behaviour (individuals with more internal or external control), focusing on the role of dopamine, serotonin and the effects of stress-related challenges in relation to their different position in a dominance hierarchy. I will subsequently allude to potential psychological and behavioural problems in the social domain following on from these differences in locus of control ['social obliviousness' (dorsal stratum) and 'social impulsivity' (ventral striatum)]. In doing so, I provide as a tribute a historical account of the early research by Lex Cools.

Hydrocarbons in Argentina: networks, territories, integration

International Nuclear Information System (INIS)

Carrizo, S.C.

2003-12-01

Argentinean hydrocarbons networks have lived a huge reorganizing the structure, after the State reform in the 90's. Activities deregulation and the privatization of YPF and Gas del Estado forced the sector re-concentration, since then dominated by foreign companies, leaded by Repsol YPF. The hydrocarbons federalization contributed to the weakening and un-capitalization loss of wealth of the State. These changes resulted in an increase of the hydrocarbons production allowing to achieve the self-supply. Nevertheless, the expansion of internal networks has not been large enough to ensure the coverage of new requirements. Besides, several infrastructures have been built up to join external markets. National networks are connected to those of near neighboring countries. This integration is an opportunity for the 'South Cone' countries to enhance their potentials. In the country, hydrocarbons territories undergo the reorganizing the structure effects (unemployment, loss of territorial identity, etc). With many difficulties and very different possibilities, those territories, like Comodoro Rivadavia, Ensenada et and Bahia Blanca, look for their re-invention. (author)

2008-01-01

The will of building up an international thermonuclear experimental reactor (ITER) gathers since several years the European community of atomic energy (Euratom), Japan, the USA, and Russia, next followed by China, South Korea and, since 2005, by India. The agreement signed in Paris between these seven parties on November 21, 2006 entrusted the international organization ITER with the realization of this project. The implications of the ITER project are enormous both in their scientific and in their economical aspects. France has a particular position in this project since the head office of ITER organisation is sited at Saint-Paul-lez-Durance and the tokamak will be built at Cadarache. Therefore, an agreement has been signed between ITER organization and the French government. The approval of this agreement is the object of this project of law made of a single article. The agreement between the French government and the international organization ITER is attached to the document. It defines the juridical status, the privileges and immunities of the organization itself and of its personnel inside the French territory. An appendix to the agreement precises the cooperation modalities between the French authorities and ITER organization. (J.S.)

To reconstruct space distribution of iodine-131 on the territory of Belarus we used the following data: (i) contents of iodine-131 in soil measured by gamma spectrometry method in May-July, 1986; (ii) contents of iodine-131 in samples of radioactive atmospheric fall-outs measured by gamma spectrometry method in May, 1986; (iii) daily measurements of exposure dose power levels on the territory of Belarus obtained in April-July, 1986; (iv) results of aerial gamma radiation mapping, obtained in May, 1986; (v) daily measurements of radioactive contamination of milk on the territory of Belarus obtained in May-July, 1986; (vi) measurements of iodine-131 content in links of biological chain 'soil-grass-milk' sampled from 15 reference farms; (vii) maps of specific activity of natural hayfields grass on the territory of Belarus (for every district) obtained on June 2 and 5, on July 3, 1986. Dose commitments on thyroid gland caused by iodine isotopes were formed mainly during the first 2.5 months after the accident. Local irradiation of this organ was stipulated by high accumulation factor of iodine isotopes in thyroid gland that caused increasing of malignant thyroid tumors incidences, including children, on all over the territory of Belarus. Comparison of iodine-131 distribution map and malignant thyroid gland tumor incidences among children on the territory of Belarus map shows that the more level of iodine contamination the more malignant thyroid gland tumor incidence

The evolutionarily conserved Toll signaling pathway controls innate immunity across phyla and embryonic patterning in insects. In the Drosophila embryo, Toll is required to establish gene expression domains along the dorsal-ventral axis. Pathway activation induces degradation of the IκB inhibitor Cactus, resulting in a ventral-to-dorsal nuclear gradient of the NFκB effector Dorsal. Here, we investigate how cactus modulates Toll signals through its effects on the Dorsal gradient and on Dorsal target genes. Quantitative analysis using a series of loss- and gain-of-function conditions shows that the ventral and lateral aspects of the Dorsal gradient can behave differently with respect to Cactus fluctuations. In lateral and dorsal embryo domains, loss of Cactus allows more Dorsal to translocate to the nucleus. Unexpectedly, cactus loss-of-function alleles decrease Dorsal nuclear localization ventrally, where Toll signals are high. Overexpression analysis suggests that this ability of Cactus to enhance Toll stems from the mobilization of a free Cactus pool induced by the Calpain A protease. These results indicate that Cactus acts to bolster Dorsal activation, in addition to its role as a NFκB inhibitor, ensuring a correct response to Toll signals. © 2017.

TERRITORIAL RISK ASSESMENT AFTER TERRORIST ACT: EXPRESS MODEL

Directory of Open Access Journals (Sweden)

M. M. Biliaiev

2018-02-01

Full Text Available Purpose. The paper involves the development of a method to assess the territorial risk in the event of a terrorist attack using a chemical agent. Methodology. To describe the process of chemical agent scattering in the atmosphere, ejected in the event of a terrorist attack, the equation of mass transfer of an impurity in atmospheric air is used. The equation takes into account the velocity of the wind flow, atmospheric diffusion, the intensity of chemical agent emission, the presence of buildings near the site of the emission of a chemically hazardous substance. For numerical integration of the modeling equation, a finite difference method is used. A feature of the developed numerical model is the possibility of assessing the territorial risk in the event of a terrorist attack under different weather conditions and the presence of buildings. Findings. A specialized numerical model and software package has been developed that can be used to assess the territorial risk, both in the case of terrorist attacks, with the use of chemical agents, and in case of extreme situations at chemically hazardous facilities and transport. The method can be implemented on small and medium-sized computers, which allows it to be widely used for solving the problems of the class under consideration. The results of a computational experiment are presented that allow estimating possibilities of the proposed method for assessing the territorial risk in the event of a terrorist attack using a chemical agent. Originality. An effective method of assessing the territorial risk in the event of a terrorist attack using a chemically hazardous substance is proposed. The method can be used to assess the territorial risk in an urban environment, which allows you to obtain adequate data on possible damage areas. The method is based on the numerical integration of the fundamental mass transfer equation, which expresses the law of conservation of mass in a liquid medium. Practical

Anatomy and muscle activity of the dorsal fins in bamboo sharks and spiny dogfish during turning maneuvers.

Science.gov (United States)

Maia, Anabela; Wilga, Cheryl D

Stability and procured instability characterize two opposing types of swimming, steady and maneuvering, respectively. Fins can be used to manipulate flow to adjust stability during swimming maneuvers either actively using muscle control or passively by structural control. The function of the dorsal fins during turning maneuvering in two shark species with different swimming modes is investigated here using musculoskeletal anatomy and muscle function. White-spotted bamboo sharks are a benthic species that inhabits complex reef habitats and thus have high requirements for maneuverability. Spiny dogfish occupy a variety of coastal and continental shelf habitats and spend relatively more time cruising in open water. These species differ in dorsal fin morphology and fin position along the body. Bamboo sharks have a larger second dorsal fin area and proportionally more muscle insertion into both dorsal fins. The basal and radial pterygiophores are plate-like structures in spiny dogfish and are nearly indistinguishable from one another. In contrast, bamboo sharks lack basal pterygiophores, while the radial pterygiophores form two rows of elongated rectangular elements that articulate with one another. The dorsal fin muscles are composed of a large muscle mass that extends over the ceratotrichia overlying the radials in spiny dogfish. However, in bamboo sharks, the muscle mass is divided into multiple distinct muscles that insert onto the ceratotrichia. During turning maneuvers, the dorsal fin muscles are active in both species with no differences in onset between fin sides. Spiny dogfish have longer burst durations on the outer fin side, which is consistent with opposing resistance to the medium. In bamboo sharks, bilateral activation of the dorsal in muscles could also be stiffening the fin throughout the turn. Thus, dogfish sharks passively stiffen the dorsal fin structurally and functionally, while bamboo sharks have more flexible dorsal fins, which result from a

The locations of 22 territorial gray wolves (Canis lupus) killed by conspecifics in northeastern Minnesota were analyzed in a study involving radio-telemetry from 1968 through 1992. Twenty-three percent of the wolves were killed precisely on the borders of their estimated territories; 41%, within 1.0 km (16% of the radius of their mean-estimated territory) inside or outside the estimated edge; 91%, within 3.2 km inside or outside (50% of the radius of their mean-estimated territory) of the estimated edge. This appears to be the first report of intraspecific mortality of mammals along territorial boundaries.

The ergonomic analysis of a control or a supervision workstation for a vehicle or a process, necessitates to take into account the biomecanical visuo-postural system. The measurements, which are necessary to do, must give informations about the spatial direction of the limbs, the dorsal shape, eventually the eyes direction, and the postural evolution during the working time. More, the smallness of the work station, the backrest and sometime a vibratory environment made use specific, strong and small devices wich do not disturb the operator. The measurement system which we propose is made of an optical device. This system is studied in relation with the french "Institute de Recherche pour les Transports" for an ergonomic analysis of a truck cabin. The optical device consists on placing on the body of the driver on particular places materializing specially members and trunck joint points, some drops which reflect the infra-red raies coming from a specific light. Several cameras whose relative positions depend on the experiment site, transmit video signals to the associated treatment systems which extract the coordinates (Xi, Yi) of each drop in the observation scope of any camera. By regrouping the informations obtained from every view, it is possible to obtain the spatial drop position and then to restore the individual's posture in three dimensions. Therefore, this device doesn't enable us, in consideration of the backrest, to analyse the dorsal posture, which is important with regard to dorsal pains frequency. For that reason, we complete the measurements by using a "curvometer". This device consists of a flexible stick fixed upon the individual back with elastic belts, whose distorsions (curvature in m-1) are measured, in the individual's sagittal plane, with 4 strain gauges pairs; located approximately at the level of vertebra D1, D6, D10 and L3. A fifth measurement, concerning the inclination (in degree) of the lower part of the stick, makes it is possible to

Full Text Available The aim of this study was to describe the anatomical arrangement of the branches arising from the dorsal surface of the aorta abdominalis in the rabbit and the hare. The study was carried out on ten adult rabbits and ten adult European hares using the corrosion technique. After the euthanasia, the vascular network was perfused with saline. After polymerization of the casting medium, the maceration was carried out in a KOH solution. We found different variations in; the number of arteries, level of their origin and arrangement. The aa. lumbales of the same level arose by means of a common trunk or their origin was independent. The aa. lumbales VI or aa. lumbales VI et VII originated also from the a. sacralis mediana. By aa. lumbales we found an important interspecies difference in; number, diameter, ramification and density of dorsal branches, which are designated for the dorsal muscles of the body stem. All listed parameters of branches were higher in the hare. This anatomical arrangement of dorsal branches is adapted to the higher movement activity of the hare. According to our results, it can be concluded that the anatomical arrangement of the branches of the aorta abdominalis shows a higher number of variations in the domesticated rabbit in comparison with the hare.

Seleznev, V. S.; Soloviev, V. M.; Emanov, A. F.

The outcomes of modern geophysical researches of the Geophysical Survey SB RAS, directed on study of geodynamic situation in large industrial and civil centers on the territory of Siberia with the purpose of an evaluation of seismic risk of territories and prediction of origin of extreme situations of natural and man-caused character, are pre- sented in the paper. First of all it concerns the testing and updating of a geoinformation system developed by Russian Emergency Ministry designed for calculations regarding the seismic hazard and response to distructive earthquakes. The GIS database contains the catalogues of earthquakes and faults, seismic zonation maps, vectorized city maps, information on industrial and housing fund, data on character of building and popula- tion in inhabited places etc. The geoinformation system allows to solve on a basis of probabilistic approaches the following problems: - estimating the earthquake impact, required forces, facilities and supplies for life-support of injured population; - deter- mining the consequences of failures on chemical and explosion-dangerous objects; - optimization problems on assurance technology of conduct of salvage operations. Using this computer program, the maps of earthquake risk have been constructed for several seismically dangerous regions of Siberia. These maps display the data on the probable amount of injured people and relative economic damage from an earthquake, which can occur in various sites of the territory according to the map of seismic zona- tion. The obtained maps have allowed determining places where the detailed seismo- logical observations should be arranged. Along with it on the territory of Siberia the wide-ranging investigations with use of new methods of evaluation of physical state of industrial and civil establishments (buildings and structures, hydroelectric power stations, bridges, dams, etc.), high-performance detailed electromagnetic researches of ground conditions of city

To explore the feasibility of applying a dorsal free graft to treat urethral stricture by the ventral sagittal urethrotomy approach without mobilizing the urethra. Twelve patients with long or multiple strictures of the anterior urethra were treated by a dorsal free full-thickness preputial or buccal mucosa graft. The urethra was not separated from the corporal bodies and was opened in the midline over the stricture. The floor of the urethra was incised, and an elliptical raw area was created over the tunica on which a free full-thickness graft of preputial or buccal mucosa was secured. The urethra was retubularized in one stage. After a follow-up of 8 to 40 months, one recurrence developed and required dilation. The ventral sagittal urethrotomy approach for dorsal free graft urethroplasty is not only feasible and successful, but is easy to perform.

To describe the technique and results of dorsal onlay lingual mucosal graft (LMG) urethroplasty for the definitive management of urethral strictures in women. In all, 15 women (mean age 42 years) with a history suggestive of urethral stricture who had undergone multiple urethral dilatations and/or urethrotomy were selected for dorsal onlay LMG urethroplasty after thorough evaluation, from October 2006 to March 2008. After a suprameatal inverted-U incision, the dorsal aspect of the urethra was dissected and urethrotomy was done at the 12 o'clock position across the strictured segment. Tailored LMG harvested from the ventrolateral aspect of the tongue was then sutured to the urethrotomy wound over an 18 F silicone catheter. The preoperative mean maximum urinary flow rate of 7.2 mL/s increased to 29.87 mL/s, 26.95 mL/s and 26.86 mL/s with a 'normal' flow rate curve at 3, 6 and 12 months follow-up, respectively. One patient at the 3-month follow-up had submeatal stenosis and required urethral dilatation thrice at monthly intervals. At the 1-year follow-up, none of the present patients had any neurosensory complications, urinary incontinence, or long-term functional/aesthetic complication at the donor site. LMG urethroplasty using the dorsal onlay technique should be offered for correction of persistent female urethral stricture as it provides a simple, safe and effective approach with durable results.

Shape representations in the primate dorsal visual stream

Tom eTheys

2015-04-01

Full Text Available The primate visual system extracts object shape information for object recognition in the ventral visual stream. Recent research has demonstrated that object shape is also processed in the dorsal visual stream, which is specialized for spatial vision and the planning of actions. A number of studies have investigated the coding of 2D shape in the anterior intraparietal area (AIP, one of the end-stage areas of the dorsal stream which has been implicated in the extraction of affordances for the purpose of grasping. These findings challenge the current understanding of area AIP as a critical stage in the dorsal stream for the extraction of object affordances. The representation of three-dimensional (3D shape has been studied in two interconnected areas known to be critical for object grasping: area AIP and area F5a in the ventral premotor cortex (PMv, to which AIP projects. In both areas neurons respond selectively to 3D shape defined by binocular disparity, but the latency of the neural selectivity is approximately 10 ms longer in F5a compared to AIP, consistent with its higher position in the hierarchy of cortical areas. Furthermore F5a neurons were more sensitive to small amplitudes of 3D curvature and could detect subtle differences in 3D structure more reliably than AIP neurons. In both areas, 3D-shape selective neurons were co-localized with neurons showing motor-related activity during object grasping in the dark, indicating a close convergence of visual and motor information on the same clusters of neurons.

Constitutionalism, State and territory in the globalization context

William Guillermo Jiménez

2012-12-01

Full Text Available Globalization shows that the national State is losing the monopoly in the production of law, and this generates changes concerning the environment of application of the state legal arrangements and the role of the territory as the limit thereof. The object of this work is to offer a panorama about of the law globalization impacts on the State, the constitutional theory and the territory. The study is performed by means of the documentary review technique by using the consultation of diverse sources. Our conclusion is that the Westphalian model of State-nation has been weakened; however, globalization needs the State to be able to operate. Law has been deterritorialized and the territory continues to be a fundamental element for the contemporary State.

To investigate the relationship between the level of collateral circulation and perfusion territory normalisation after carotid endarterectomy (CEA). This study enrolled 22 patients with severe carotid stenosis that underwent CEA and 54 volunteers without significant carotid stenosis. All patients were scanned with ASL and t-ASL within 1 month before and 1 week after CEA. Collateral circulation was assessed on preoperative ASL images based on the presence of ATA. The postoperative flow territories were considered as back to normal if they conformed to the perfusion territory map in a healthy population. Neuropsychological tests were performed on patients before and within 7 days after surgery. ATA-based collateral score assessed on preoperative ASL was significantly higher in the flow territory normalisation group (n=11, 50 %) after CEA (P mean differences+2SD among control (MMSE=1.35, MOCA=1.02)]. This study demonstrated that effective collateral flow in carotid stenosis patients was associated with normalisation of t-ASL perfusion territory after CEA. The perfusion territory normalisation group tends to have more cognitive improvement after CEA. • Evaluation of collaterals before CEA is helpful for avoiding ischaemia during clamping. • There was good agreement on ATA-based ASL collateral grading. • Perfusion territories in carotid stenosis patients are altered. • Patients have better collateral circulation with perfusion territory back to normal. • MMSE and MOCA test scores improved more in the territory normalisation group.

How memory of direct animal interactions can lead to territorial pattern formation.

Science.gov (United States)

Potts, Jonathan R; Lewis, Mark A

2016-05-01

Mechanistic home range analysis (MHRA) is a highly effective tool for understanding spacing patterns of animal populations. It has hitherto focused on populations where animals defend their territories by communicating indirectly, e.g. via scent marks. However, many animal populations defend their territories using direct interactions, such as ritualized aggression. To enable application of MHRA to such populations, we construct a model of direct territorial interactions, using linear stability analysis and energy methods to understand when territorial patterns may form. We show that spatial memory of past interactions is vital for pattern formation, as is memory of 'safe' places, where the animal has visited but not suffered recent territorial encounters. Additionally, the spatial range over which animals make decisions to move is key to understanding the size and shape of their resulting territories. Analysis using energy methods, on a simplified version of our system, shows that stability in the nonlinear system corresponds well to predictions of linear analysis. We also uncover a hysteresis in the process of territory formation, so that formation may depend crucially on initial space-use. Our analysis, in one dimension and two dimensions, provides mathematical groundwork required for extending MHRA to situations where territories are defended by direct encounters. © 2016 The Author(s).

La dinámica territorial de las principales instituciones bancarias en la península de Baja California: estructura e interrelaciones

Full Text Available This research analyzes the territorial distribution of the main banking institutions within the Baja California peninsula´s urban space. It starts by providing a background on the spatial organization of banking institutions in the study area and their relationship within the national context, stressing their borderline location. The location-focused analysis, through examining the territorial distribution of the 158 bank offices from the seven main Institutions, allows to detect a considerable concentration in small and mid-sized urban towns located to the north. Also, banks tend to be located at the most populated towns having differential behaviors. Since this aspect is related to the economic activity that takes place in them, these towns have become preferential spaces, resulting in territorial unbalances. The cities of Tijuana and Mexicali stand out, followed to a lesser extent by La Paz and Ensenada, The territorial distribution of banking institutions in Baja California follows the same behavior pattern as the one that occurs at a national level, i.e. location according to the specific area of specialty.

The aim of this study was to determine the normal location, wall thickness and motility of the right dorsal colon in adult ponies and miniature horses. The abdominal ultrasonography examination was performed in a study group consisting of 23 ponies and miniature horses and in a control group comprising ten Thoroughbred horses. The procedure was performed in unsedated standing animals. The location and the thickness of the right dorsal colonic wall was examined on the right side of the abdomen between the 10th and the 14th intercostal space. The contractility was recorded in the 12th intercostal space. A comparative analysis between the study group and control group was carried out using the Student’s t-test. Pearson’s linear correlation coefficient was used to calculate the correlation between the thickness of the colonic wall as well as the number of peristaltic movements and age, wither height and body mass of the animals. The right dorsal colon was identified in all the horses in the 12th intercostal space. In all the intercostal spaces the mean ± standard deviation (SD) wall thickness of the right dorsal colon was 0.27 ± 0.03 cm in the horses from the study group and 0.37 ± 0.03 cm in the control horses. The mean number of peristaltic contractions was 4.05 ± 1.07 per minute in the animals from the study group and 1.7 ± 0.46 contractions per minute in the control group. The values of the ultrasonographic wall thickness and peristaltic motility in small breed horses in the present study were different from the values obtained for large breed horses. The study also found that the right dorsal colon in small breed horses is physiologically located in the 12th intercostal space. This suggests that different reference values should be used in small horse breeds when performing an ultrasound examination. PMID:29065146

Full Text Available Since the end of the 1960s, the eclosion of a planetary problematics related to the recognition of the “ecological limits of material growth” has mobilized growing attention on the part of scientific communities and public opinion. The systemic concept of eco-development has emerged from this context and been gradually disseminated as a an expression of the radical critique of the economistic ideology underlying industrial-technological “civilization”. Over the course of the 1980s and 1990s, the proliferation of case studies on experiences of local and territorial development in different national contexts has contributed to a deepening of (systemic notions of endogeneity, de-centralization, self-reliance, local autonomy and integrated local productive systems, which have always considered bases of the ecodevelopmentalist position. Against the background of the uncertainties, constraints and opportunities imposed by assymetrical globalization, special attention began to be given to the analysis of the innovative and synergic responses – in terms of socio-economic, socio-cultural and political-institutional reorganization – that have been generated within these spaces. Furthermore, and in a rather paradoxical way, most of the studies linked to a territorial focus give little attention to the treatment of the immense challenges brought about through the elosion of socioenvironmental crisis and the appearance of a vast literature dealing with the connection between environment and development. The present article offers exploratory subsidies that attempt to overcome the aforementioned lacunae, evaluating both the pertinence and general conditions of viability of the sustainable territorial development approach at the current stage of evolution of the Brazilian environmental agenda. Keywords: systemic research, ecological policy, environmental policy, sustainable territorial development.

Dorsal column sensory axons degenerate due to impaired microvascular perfusion after spinal cord injury in rats

Muradov, Johongir M.; Ewan, Eric E.; Hagg, Theo

The mechanisms contributing to axon loss after spinal cord injury (SCI) are largely unknown but may involve microvascular loss as we have previously suggested. Here, we used a mild contusive injury (120 kdyn IH impactor) at T9 in rats focusing on ascending primary sensory dorsal column axons, anterogradely traced from the sciatic nerves. The injury caused a rapid and progressive loss of dorsal column microvasculature and oligodendrocytes at the injury site and penumbra and a ~70% loss of the sensory axons, by 24 hours. To model the microvascular loss, focal ischemia of the T9 dorsal columns was achieved via phototoxic activation of intravenously injected rose bengal. This caused an ~53% loss of sensory axons and an ~80% loss of dorsal column oligodendrocytes by 24 hours. Axon loss correlated with the extent and axial length of microvessel and oligodendrocyte loss along the dorsal column. To determine if oligodendrocyte loss contributes to axon loss, the glial toxin ethidium bromide (EB; 0.3 µg/µl) was microinjected into the T9 dorsal columns, and resulted in an ~88% loss of dorsal column oligodendrocytes and an ~56% loss of sensory axons after 72 hours. EB also caused an ~72% loss of microvessels. Lower concentrations of EB resulted in less axon, oligodendrocyte and microvessel loss, which were highly correlated (R2 = 0.81). These data suggest that focal spinal cord ischemia causes both oligodendrocyte and axon degeneration, which are perhaps linked. Importantly, they highlight the need of limiting the penumbral spread of ischemia and oligodendrocyte loss after SCI in order to protect axons. PMID:23978615

Mechanisms underlying the organizer formation in Bufo arenarum embryos.

Manes, M E; Nieto, O L

In the early gastrula of Bufo arenarum the prospective mesoderm was previously identified as a marginal belt of grey cells. To analyze their differentiation capacity explants of these cells were cultured within ectodermal vesicles, in isolation and in combination with vegetal components. When cultured in isolation, dorsal and ventral fragments from the deep marginal zone behaved differently. Whilst ventral explants produced blood cells, dorsal explants failed to differentiate, remaining as masses of yolk-laden cells. On the other hand, both cultures were drastically modified when associated with superficial cells from the blastoporal zone, which caused the following effects: a) Promotion of differentiation in dorsal marginal explants, able now to produce notochordal and somitic structures, in addition to mesenchymatic cells. b) Promotion of dorsalization in ventral marginal explants, which changed their expected destiny developing axial components, similar to those furnished by "activated" dorso marginal explants. On the contrary, combined cultures of animal and vegetal pieces were unable to generate mesodermal structures. These studies suggest that the axial mesoderm, identified as the "organizer", develops from a marginal substrate of genuine mesodermal cells through a dorsalizing inductive stimulus originated in superficial periblastoporal cells.

Rare patterns of dorsal puncture in Pterostichus oblongopunctatus (Coleoptera: Carabidae

2018-04-01

Full Text Available Background The carabid beetle species Pterostichus oblongopunctatus is common in different types of forests in Poland and Europe. With respect to this species, some unclarities exist concerning the morphological feature of punctures on the elytra. P. oblongopunctatus has dorsal pits in the third interval of the elytra, the available identification keys, however, provide inconsistent information concerning the puncture in other intervals. During long-term studies at different study sites in Poland, the first author rarely but regularly discovered individuals with unusual dorsal puncture patterns, i.e., pits in the fifth and even in the seventh interval of the elytra. Since such rare patterns might be connected with special habitat characteristics, and thus have a potential as an indicator, the aim of the study was to test if they are connected with specific subpopulations (interaction groups, if they are related to the sex or size of the beetles, and if they are related to specific habitat conditions. Material and Methods We counted the pits on the elytra, determined the sex, and measured the length of the right elytron of individuals of P. oblongopunctatus collected at numerous study sites located within the borders of the Regional Directory of National Forests in Piła (Western Poland over the period 2014–2016. Results Altogether, 1,058 individuals of P. oblongopunctatus were subjected to statistical analysis. Almost 19% of the individuals had a dorsal puncture in the fifth interval of the elytra and about 0.7% had a dorsal puncture in the seventh interval of the elytra. In 2014 and 2015, significantly more females exhibited such unusual patterns of dorsal puncture than males. Even if not statistically significant, in 2016 also relatively more females showed such a pattern. Neither males nor females of the analysed individuals with usual puncture patterns showed a significant difference in the length of the right elytron from those with

Local authorities and electricity: territories, actors and issues within the local public service in France

International Nuclear Information System (INIS)

Bouvier, G.

2005-06-01

In France, the role of local authorities in the organization of the electricity supply system is largely unknown mainly due to the size of the state-owned utility Electricite de France (EDF). Local authorities and their groupings played a major role in the electrification of the national territory and have kept important prerogatives as conceding authorities of this service of general interest. These groupings also became the tools of the soft power of local actors. The geopolitical analysis of the relationships between local municipalities and electric power stakeholders shows the diversity of actors and opinions. Stuck between market liberalization issues and decentralization to local authorities, these groupings tend to reinforce their competencies. Furthermore, decentralization goes along with a reinforcement of the political involvement in local energy policy and with conflicts on the adequate territorial scale for theses policies. (author)

REVIEW OF THE EUROPEAN SYSTEMS RESEARCH PROGRAMS OF URBAN TERRITORIES

Directory of Open Access Journals (Sweden)

2017-01-01

Full Text Available The model of sustainable development of the territory should be in a state of control and management. The system of urban monitoring of Ukraine does not fully provide information on the level of sustainable development of settlements and regions. Therefore, it is necessary to create systems for monitoring indicators of sustainable development of human settlements and regions. The objective of this study is to analyze the existing programs for stimulating sustainable development in European countries and to develop recommendations on the need to organize such systems in Ukraine and to improve the system of urban monitoring. The article describes such systems and programs: URBACT is a program for sharing best practices between cities by creating thematic networks. URBACT’s mission is to encourage cities to work together and develop integrated solutions to common urban problems, through networking, to learn from each other’s experiences and identify best practices in order to improve urban policies; URBAN AUDIT – a large set of statistical information. The main objective of the system is to provide objective and comparable statistical data on European cities; URBAN ATLAS – provides a pan-European comparison of urban land use data. The information is in the form of open geospatial data. The system is aimed at facilitating work on site planning and site accounting. It is necessary to adopt the best practices of implementing sustainable development technology and apply it in other countries that have chosen a model for their development – a model for sustainable development of the territory. The current system of town-planning monitoring in Ukraine needs to be improved and given a new task – to take into account indicators of sustainable development of the territories. This system is most suitable for this task, since urban monitoring already takes into account certain indicators in the form of spatial data.

Full Text Available Effects of thalamic nuclei damage and related white matter tracts on memory performance are still debated. This is particularly evident for the medio-dorsal thalamus which has been less clear in predicting amnesia than anterior thalamus changes. The current study addresses this issue by assessing 7 thalamic stroke patients with consistent unilateral lesions focal to the left medio-dorsal nuclei for immediate and delayed memory performance on standard visual and verbal tests of anterograde memory, and over the long-term (> 24 hrs on an object-location associative memory task. Thalamic patients showed selective impairment to delayed recall, but intact recognition memory. Patients also showed accelerated forgetting of contextual information after a 24 hour delay, compared to controls. Importantly, the mammillothalamic tract was intact in all patients, which suggests a role for the medio-dorsal nuclei in recall and early consolidation memory processes.

Full Text Available This article considers the main features of sustainable development of rural territories, identifies the factors of innovative entrepreneurship, and assesses their influence on the condition of rural economy. Special attention is paid to the analysis of concepts, programmes, and projects in the field of rural territory development. The authors summarise conceptual and strategic approaches and actions of the Baltic region states in the field of sustainable development of rural territories. The article identifies objectives, common for the Baltic region, relating to sustainability of rural territories, including sustainable use of natural resource potential, diversification of production through support for non-agricultural activities and employment, application of innovations and efficient technologies, and manufacturing of environmentally friendly products. The analysis of the development of agricultural and innovations in the Baltic Sea regions serves as a basis for identifying the factors and conditions of supporting innovative entrepreneurship. Of special importance are the research, technological, and innovative potential of the territory, the availability of adequate innovative infrastructure, and the formation of innovative culture. The authors corroborate the idea of innovative entrepreneurship development in rural territories through the transformation of organizational and economic mechanism of management relating to the creation of institutional, infrastructure, and spatial conditions. Research and technological cooperation in the Baltic region is emphasised as a priority area.

2013-09-01

Full Text Available The paper shows that the traditional outlook on development of territories as the process of alignment of their socio-economic development with the help of external influences should be advanced and replaced by a new vision. The purpose of the work is the definition of the basic rules of the concept of vital stability of territories. The creation by the local population of the riches and well being by expansion of manufacturing industry on the basis of the use of intelligence — technological and moral — ethical factors are shown as the basic contents of the offered concept. A consequence of such approach is the growing feedback of made expenses, as technologically completed production will be realized but not raw material or semi-finished item. Only the differentiation industrial development of the territory is capable to deduce it from a condition of poverty and depression. The understanding of development of the territory as creation of conditions for growth of people’s wellbeing and formation of a man as a person is opened. The accent of the attention on the promotion of a man not only as the purpose of transformation of territory, but also as the factor of its safe development through an increase of his or her intellectual and spiritual levels is made. The measures and instruction on innovation to the strengthening of vital stability of territories are offered. The separate results of research were used at the prolongation of the Plan for strategic development of Yekaterinburg up to 2020. Authorities of territories at the formation of their development strategy can apply the new offered rules.

Territorial Identity and Grassroots Economic Activism: The Politicization of Farmers’ Mobilizations in the French Basque Country

Directory of Open Access Journals (Sweden)

Xabier Itçaina

2015-07-01

Full Text Available The French Basque Country (FBC represents an emblematic case of the politicization of local development through grassroots economic activism. These mobilizations are particularly obvious in the agricultural sector. Based on a qualitative research on small farmers’ organizations and short food circuits, this article shows that Basque farmers’ mobilizations constitute a case of a dual politicization of small-scale farming and territorial identity. This process has gone through two phases: the first period (1970-2000 was characterized by the politicization of local productive systems. Throughout the decade 2000-2010, a new mode of grassroots economic activism emerged, signalled by new alliances between producers and consumers, and by an increasing ideological pluralism. Two case studies illustrate these developments. The first relates to a case of explicit politicization with the controversy around the foundation in 2005 of an alternative Basque Chamber of Agriculture. The second case study is devoted to the development of short food circuits in the FBC, considered here as a case of implicit politicization of the encounter between productive and consumption circuits. Both cases illustrate the politicization of new economic social movements, and the constant overlapping of sectoral and territorial claims in the Basque territory.

Protecting the turf: The effect of territorial marking on others' creativity.

Science.gov (United States)

Brown, Graham; Baer, Markus

2015-11-01

Territorial marking allows people to communicate that a territory has been claimed. Across 2 studies, we examine the impact of territorial marking of one's ideas on others' invited creativity when asked to provide feedback. Integrating research on territoriality and self-construal, we examine the effect of control-oriented marking on invited creativity (Study 1), and the extent to which an independent versus interdependent self-construal moderates this effect (Study 2). Results of Study 1 demonstrate that the use of control-oriented marking to communicate a territorial claim over one's ideas inhibits invited creativity, and this effect is mediated by intrinsic motivation. Also consistent with our hypotheses, the results of Study 2 show that self-construal moderates the effect of control-oriented marking on others' intrinsic motivation and creativity. Marking diminishes invited creativity among people with an independent self-construal but serves to enhance the creativity of those with an interdependent self-construal. Consistent with Study 1, intrinsic motivation mediates this moderated effect. Our results highlight the important but heretofore understudied role of territoriality in affecting others' creativity as well as the role of independent versus interdependent self-construal in shaping this effect.

Dorsal inlay buccal mucosal graft (Asopa) urethroplasty for anterior urethral stricture.

Marshall, Stephen D; Raup, Valary T; Brandes, Steven B

2015-02-01

Asopa described the inlay of a graft into Snodgrass's longitudinal urethral plate incision using a ventral sagittal urethrotomy approach in 2001. He claimed that this technique was easier to perform and led to less tissue ischemia due to no need for mobilization of the urethra. This approach has subsequently been popularized among reconstructive urologists as the dorsal inlay urethroplasty or Asopa technique. Depending on the location of the stricture, either a subcoronal circumferential incision is made for penile strictures, or a midline perineal incision is made for bulbar strictures. Other approaches for penile urethral strictures include the non-circumferential penile incisional approach and a penoscrotal approach. We generally prefer the circumferential degloving approach for penile urethral strictures. The penis is de-gloved and the urethra is split ventrally to exposure the stricture. It is then deepened to include the full thickness of the dorsal urethra. The dorsal surface is made raw and grafts are fixed on the urethral surface. Quilting sutures are placed to further anchor the graft. A Foley catheter is placed and the urethra is retubularized in two layers with special attention to the staggering of suture lines. The skin incision is then closed in layers. We have found that it is best to perform an Asopa urethroplasty when the urethral plate is ≥1 cm in width. The key to when to use the dorsal inlay technique all depends on the width of the urethral plate once the urethrotomy is performed, stricture etiology, and stricture location (penile vs. bulb).

Full Text Available The strategy to strengthen the field of rural development planning aims the search for social cohesion, regional competitiveness and environmental sustainability of the territories. In this sense, the current uncertain context characterized by the globalization of the economy, increasing demand for energy, erosion and pressure on natural resources demand for innovative models that promote rural development territorial strategies that give priority to local resources and that support local development models  In this stage, the model of territorial planning is established as a preferred option on models of local development settled under the concept of the municipality, since mobilizes resources and capabilities between regions that have common strengths and opportunities for promoting development and exceeding the vision and concept of the local as political-administrative unit. It is in this supra-municipal and territorial approach where Biosphere Reserves are an opportunity for sustainable territorial development.

Decreased resting-state BOLD regional homogeneity and the intrinsic functional connectivity within dorsal striatum is associated with greater impulsivity in food-related decision-making and BMI change at 6-month follow up.

Science.gov (United States)

Gao, Xiao; Liang, Qianlin; Wu, Guorong; She, Ying; Sui, Nan; Chen, Hong

2018-04-30

Increasing animal models as well as brain imaging studies among human suggest an association between substance-related impulsivity in decision-making and decreased function of dorsal striatum. However, the resting-state intrinsic functional organization of dorsal striatum underlying food-choice impulsivity remains unknown. To address this issue, we used resting-state functional MRI (rs-fMRI) to measure brain activity among adult females. Subjects underwent the food rating task, during which they rated each food item according to their subjective perception of its taste (from Dislike it very much to Like it very much), its long term effect on health (from very unhealthy to very healthy) and decision strength to eat it (from Strong no to Strong yes). Behaviorally, impulsivity in food-choice was indexed by the decision strength of the palatable high-calorie food rather than of the low-caloric food. Results on rs-fMRI showed that greater impulsivity in food-related decision-making was inversely correlated with spontaneous regional homogeneity in the dorsal striatum (dorsal caudate), as well as the resting-state functional connectivity (rs-FC) between the dorsal caudate seed and the rostral putamen. Furthermore, the caudate-putamen rs-FC inversely predicted BMI change at six-month follow-up. These findings may suggest the insensitivity to reward signals in dorsal caudate in decision-making coupled with an imbalance between goal-directed behaviors (modulated by dorsal caudate) and habitual actions (modulated by putamen) underlying impulsivity and future weight gain. In sum, these findings extend our understanding on the neural basis of food-related impulsivity, and provide evidence for the dorsal striatum as one of the landmarks in over eating and weight change.

Full Text Available The Spanish protectorate in Morocco was based in a High Commision as the highest authority in the area, supported by diferent delegations that promoted the sectorial policies. The Moroccan authority structure was based on a khalifa who was in charge of the government and the administration with the assistance of a central Makhzen. The political action required a territorial organization to keep the Spanish presence. However, this structure based on the Makhzen and the kabyle administration did not take into account the differences and complexity of Morocco.

Osteology of the dorsal vertebrae of the giant titanosaurian sauropod dinosaur Dreadnoughtus schrani from the Late Cretaceous of Argentina

Directory of Open Access Journals (Sweden)

Kristyn K. Voegele

2017-11-01

Full Text Available Many titanosaurian dinosaurs are known only from fragmentary remains, making comparisons between taxa difficult because they often lack overlapping skeletal elements. This problem is particularly pronounced for the exceptionally large-bodied members of this sauropod clade. Dreadnoughtus schrani is a well-preserved giant titanosaurian from the Upper Cretaceous (Campanian–Maastrichtian Cerro Fortaleza Formation of southern Patagonia, Argentina. Numerous skeletal elements are known for Dreadnoughtus, including seven nearly complete dorsal vertebrae and a partial dorsal neural arch that collectively represent most of the dorsal sequence. Here we build on our previous preliminary description of these skeletal elements by providing a detailed assessment of their serial positional assignments, as well as comparisons of the dorsal vertebrae of Dreadnoughtus with those of other exceptionally large-bodied titanosaurians. Although the dorsal elements of Dreadnoughtus probably belong to two individuals, they exhibit substantial morphological variation that suggests that there is minimal, if any, positional overlap among them. Dreadnoughtus therefore preserves the second-most complete dorsal vertebral series known for a giant titanosaurian that has been described in detail, behind only that of Futalognkosaurus. The dorsal sequence of Dreadnoughtus provides valuable insight into serial variation along the vertebral column of these enormous sauropods. Such variation includes the variable presence of divided spinodiapophyseal laminae and associated spinodiapophyseal fossae. Given that dorsal vertebrae are the only elements that overlap between known remains of most giant titanosaurian taxa, the dorsal series of Dreadnoughtus provides a means to directly compare the morphologies of these sauropods. The dorsal vertebrae of Dreadnoughtus and Futalognkosaurus have dorsoventrally narrow transverse processes, unlike the condition in Puertasaurus. Further

Nuclear industry and territories

International Nuclear Information System (INIS)

Le Ngoc, B.

2016-01-01

Nuclear industry being composed of plants, laboratories, nuclear power stations, uranium mines, power lines and fluxes of materials from one facility to another is a strong shaper of the national territory. Contrary to other European countries, French nuclear industry is present all over the national territory. In 64 departments out of 101 there is at least one enterprise whose half of the revenues depends on nuclear activities. The advantage of such a geographical dispersion is when a nuclear activity is given up the social impact is less important: people tend to find a new job in the same region. French Nuclear power plants are generally set in remote places where population density is low and being the first employer by far of the area and being a major contributor to the city revenues, they are perceived as a key element the local population is proud of. In Germany, nuclear power plants are set inside dense industrial regions and appear as an industry just like any other.(A.C.)

In this study, we compared induction of c-Fos and phosphorylated extracellular signal-regulated kinase (p-ERK) in the spinal dorsal horn after peripheral nerve injury. We examined the spinal dorsal horn for noxious heat-induced c-Fos and p-ERK protein-like immunoreactive (c-Fos- and p-ERK-IR) neuron profiles after tibial nerve injury. The effect of administration of a MEK 1/2 inhibitor (PD98059) on noxious heat-induced c-Fos expression was also examined after tibial nerve injury. A large number of c-Fos- and p-ERK-IR neuron profiles were induced by noxious heat stimulation to the hindpaw in sham-operated animals. A marked reduction in the number of c-Fos- and p-ERK-IR neuron profiles was observed in the medial 1/3 (tibial territory) of the dorsal horn at 3 and 7 days after nerve injury. Although c-Fos-IR neuron profiles had reappeared by 14 days after injury, the number of p-ERK-IR neuron profiles remained decreased in the tibial territory of the superficial dorsal horn. Double immunofluorescence labeling for c-Fos and p-ERK induced by noxious heat stimulation to the hindpaw at different time points revealed that a large number of c-Fos-IR, but not p-ERK-IR, neuron profiles were distributed in the tibial territory after injury. Although administration of a MEK 1/2 inhibitor to the spinal cord suppressed noxious heat-induced c-Fos expression in the peroneal territory, this treatment did not alter c-Fos induction in the tibial territory after nerve injury. ERK phosphorylation may be involved in c-Fos induction in normal nociceptive responses, but not in exaggerated c-Fos induction after nerve injury.

Purpose: To investigate the diagnostic performance of 64-section CTA in the detection of dorsal pancreatic artery before interventional therapy for patients with diabetes. Materials and methods: The study was approved by the institutional ethics committee; written informed consent was obtained. Forty-two consecutive patients with diabetes received an experimental treatment of autologous bone marrow-derived stem cell transplantation by means of infusion into the dorsal pancreatic artery. All cases underwent abdominal CTA before angiography of pancreatic arteries in order to locate the origin and course of dorsal pancreatic artery. Angiography of coeliac artery, splenic artery, common hepatic artery and superior mesenteric artery were performed both in CTA and DSA. Superselective catheterization of dorsal pancreatic artery was carried out for the infusion of stem cell. Sensitivity, specificity and accuracy for the detection of dorsal pancreatic artery with CTA were calculated using DSA images as the reference standard. Results: Thirty-five and thirty-six dorsal pancreatic arteries were detected by CTA and DSA respectively. Dorsal pancreatic artery was not visualized in either CTA or DSA in 5 patients. The sensitivity, specificity and accuracy for CTA were 94.4%, 83.3% and 92.9%. Conclusion: 64-section CTA is accurate for the detection of dorsal pancreatic artery. It may be useful for the facilitation of superselective arterial infusion of stem cells to pancreas.

The control-collaboration model makes various theoretical claims on the relationship between territorial control and the use and motivations of violence (whether selective or indiscriminate. This study tests two of the key claims made in the model: 1. There is an inverse relationship between level of territorial control and the use of indiscriminate violence; and, 2. The loss off territory encourages the use of indiscriminate violence. Using data on civilian and child deaths taken from the ‘Syrian Martyr Database’, this study examines the relationship between territorial control and territorial loss, and the use of indiscriminate violence by incumbent (Syrian state forces. Examining the levels of territorial control/loss and the extent of civilian and child casualties in Aleppo, Syria, results of the study largely support the theoretical assumptions outlined by Kalyvas.'

Harmane and norharmane (two beta-carbolines) are tobacco components or products. The effects of harmane and norharmane on serotonergic raphe neurons remain unknown. Harmane and norharmane are inhibitors of the monoamine oxidases A (MAO-A) and B (MAO-B), respectively. To study the effects of harmane, norharmane, befloxatone (MAOI-A), and selegiline (MAOI-B) on the firing of serotonergic neurons. To compare the effects of these compounds to those of nicotine (whose inhibitory action on serotonergic neurons has been previously described). The effects of cotinine, a metabolite of nicotine known to interact with serotonergic systems, are also tested. In vivo electrophysiological recordings of serotonergic dorsal raphe neurons in the anaesthetized rat. Nicotine, harmane, and befloxatone inhibited serotonergic dorsal raphe neurons. The other compounds had no effects. The inhibitory effect of harmane (rapid and long-lasting inhibition) differed from that of nicotine (short and rapidly reversed inhibition) and from that of befloxatone (slow, progressive, and long-lasting inhibition). The inhibitory effects of harmane and befloxatone were reversed by the 5-HT1A antagonist WAY 100 635. Pretreatment of animals with p-chlorophenylalanine abolished the inhibitory effect of befloxatone, but not that of harmane. Nicotine, harmane, and befloxatone inhibit the activity of raphe serotonergic neurons. Therefore, at least two tobacco compounds, nicotine and harmane, inhibit the activity of serotonergic neurons. The mechanism by which harmane inhibits serotonergic dorsal raphe neurons is likely unrelated to a MAO-A inhibitory effect.

Alzheimer disease: functional abnormalities in the dorsal visual pathway.

LENUS (Irish Health Repository)

Bokde, Arun L W

2012-02-01

PURPOSE: To evaluate whether patients with Alzheimer disease (AD) have altered activation compared with age-matched healthy control (HC) subjects during a task that typically recruits the dorsal visual pathway. MATERIALS AND METHODS: The study was performed in accordance with the Declaration of Helsinki, with institutional ethics committee approval, and all subjects provided written informed consent. Two tasks were performed to investigate neural function: face matching and location matching. Twelve patients with mild AD and 14 age-matched HC subjects were included. Brain activation was measured by using functional magnetic resonance imaging. Group statistical analyses were based on a mixed-effects model corrected for multiple comparisons. RESULTS: Task performance was not statistically different between the two groups, and within groups there were no differences in task performance. In the HC group, the visual perception tasks selectively activated the visual pathways. Conversely in the AD group, there was no selective activation during performance of these same tasks. Along the dorsal visual pathway, the AD group recruited additional regions, primarily in the parietal and frontal lobes, for the location-matching task. There were no differences in activation between groups during the face-matching task. CONCLUSION: The increased activation in the AD group may represent a compensatory mechanism for decreased processing effectiveness in early visual areas of patients with AD. The findings support the idea that the dorsal visual pathway is more susceptible to putative AD-related neuropathologic changes than is the ventral visual pathway.

The realities of doing business in the Northwest Territories

International Nuclear Information System (INIS)

Gullberg, E.

2000-01-01

The practical and legal issues regarding business operations in the Northwest Territories were discussed for the benefit of any enterprise wishing to conduct business in the territory. The non-renewable resources in the North are greatly responsible for the economic development in the Northwest Territories. Yellowknife was established in 1930's to service the gold mines and is now the service centre for Canada's only diamond mine located in the tundra one hour by air from Yellowknife. Other major oil and gas discoveries include Norman Wells along the Mackenzie River and the Beaufort Delta Region. In addition, new oil and gas has been discovered near Fort Liard. There is no legislation governing businesses operating in the oil and gas industry specifically, but several Acts exist where general applications would apply. This paper described the demographics of the territory and the types of government. Band councils play a significant role in local government. Much of the land in the Northwest Territories is the subject of land claims or has been transferred to indigenous people as part of settled land claims. A socio-economic agreement signed in 1996 ensures a certain percentage of northern suppliers, northern resident employees and aboriginal employees in both the construction and operation of the BHP mine. An even more demanding agreement was signed for the Diavik Diamond mine in 1999. The registration and licensing requirements that the government of the Northwest Territories imposes on businesses were described with emphasis on the Business Corporations Act, the Business License Act and the Worker's Compensation Act. Employee issues were also discussed as they relate to the Canada Labour Code, the Employment Standards Regulation, Fair Practices Act, and the Payroll Tax Act. Other regulatory requirements which would apply to the oil and gas industry include the Safety Act, the Motor Vehicles Act

PARTICULARITIES OF THE ORGANIZATION OF LOCAL PUBLIC ADMINISTRATION IN ROMANIAN AND GREEK SPACES

Full Text Available The way the public administration is organized affects the progress of the national community, in general, and of the local communities, in particular. A good management of public affairs from territorial units is not possible without the organizational design of the local administrative mechanism. From such a way, the pages of this paper are devoted to the study in mirror of the organization way of the Romanian and Greek local administrative systems, both territorially and functionally. By examining the territorial and functional administrative organisation we highlighted the peculiarities encountered and we extracted the similarities and the differences in the two local public administrations taken into consideration. As a result of the investigations conducted we found that at the basis of both local administrations are found clear regulations that expressly provide the territorial and functional organisational bases; with reference to the territorial organisation, for both administrative systems we have identified a structure with three levels of government, the difference being given by the existence of other specific territorial divisions; regarding the organs through which is realised the management of public affairs, in both administrations we find own authorities for each of the levels of government; the duration of the mandate of the Romanian local administration authorities differs from the one of the Greek administration authorities; most of administrative authorities of the two systems are elected by direct vote and only for some of them the setting occurs through indirect voting or appointment. Overall, we found that, at least regarding the criteria analyzed, between the two local public administrations there are no consistent differences, the territorial and functional organisational specificities being similar in equal measure.

Sanfratello, Lori; Aine, Cheryl; Stephen, Julia

2018-05-25

Impairments in auditory and visual processing are common in schizophrenia (SP). In the unisensory realm visual deficits are primarily noted for the dorsal visual stream. In addition, insensitivity to timing offsets between stimuli are widely reported for SP. The aim of the present study was to test at the physiological level differences in dorsal/ventral stream visual processing and timing sensitivity between SP and healthy controls (HC) using MEG and a simple auditory/visual task utilizing a variety of multisensory conditions. The paradigm included all combinations of synchronous/asynchronous and central/peripheral stimuli, yielding 4 task conditions. Both HC and SP groups showed activation in parietal areas (dorsal visual stream) during all multisensory conditions, with parietal areas showing decreased activation for SP relative to HC, and a significantly delayed peak of activation for SP in intraparietal sulcus (IPS). We also observed a differential effect of stimulus synchrony on HC and SP parietal response. Furthermore, a (negative) correlation was found between SP positive symptoms and activity in IPS. Taken together, our results provide evidence of impairment of the dorsal visual stream in SP during a multisensory task, along with an altered response to timing offsets between presented multisensory stimuli.

Scent marking in a territorial African antelope: I. The maintenance of borders between male oribi.

Science.gov (United States)

Brashares; Arcese

1999-01-01

Scent marking is ubiquitous among the dwarf antelope and gazelles of Africa, but its function has been the subject of debate. This study examined preorbital gland scent marking in the oribi, Ourebia ourebi, a territorial African antelope. Several hypotheses for the function of scent marking by territorial antelope were tested with observational data. Of these, the hypotheses that scent marking is driven by intrasexual competition between neighbouring males, and that marks serve as an honest advertisement of a male's ability to defend his territory from rivals, were supported best. Thirty-three territorial male oribi on 23 territories marked most at borders shared with other territorial males, and territorial males marked more often at borders shared with multimale groups than at borders shared with a single male. This suggests that males perceived neighbouring male groups as a greater threat to territory ownership than neighbouring males that defended their territories without the aid of adult subordinates. Marking rate was unrelated to territory size or the number of females on adjacent territories, but males with many male neighbours marked at higher rates than those with fewer male neighbours. These results suggest that the presence of male neighbours has a greater effect on the scent marking behaviour of territorial antelope than has been considered previously.

Radiological monitoring of food on the French territory

Boissieux, T.; Leprieur, F.; Pierrard, O. [Institute for Radiological Protection and Nuclear Safety (France)

2014-07-01

Drink the milk of cows grazing near French nuclear power plants is it really safe in normal times? In case of a nuclear accident leading to release in the environment, what kind of foodstuff can we still eat? In his regulatory mission of environmental monitoring, the French Institute for Radiological Protection and Nuclear Safety (IRSN) tends to answer these questions by acquiring radioactivity data in the food chain. Food radiological monitoring program by IRSN is implemented with a three scale strategy. Locally, i.e. within the range 0 to 10 kilometers of nuclear installations, foodstuff locally produced and thus potentially exposed to radioactive sources are frequently sampled and analyzed. At the regional level, specific studies are carried out to establish an updated levels baseline of radioactivity in the environment, especially in agricultural productions characteristic of the area concerned. At the national level, monitoring food aims to map the average contamination observed all around the French territory. This work of vigilance is organized in partnerships with other French actors involved in food monitoring. In the event of a nuclear accident or small-scale incidents, it would allow having an efficient support network of samplers and measurers located on the whole French territory and quickly mobilized in short or medium terms. Since 2008, IRSN has developed a food monitoring program with the Directorate general for food (DGAL) and the Directorate general for competition policy, consumer affairs and fraud control (DGCCRF). These directions have a general mission of food safety control (animal and plant products) and animal feed-stuff, which requires the search for chemical, physical, biological and radioactive substances. Likewise, a sampling program of grain products is efficient since 1969 with the support of France Agrimer. In 2013, the food monitoring is based on multi-radionuclides analysis (cesium, iodine, tritium, alpha emitters...) in about 650

Characterisation of rebound depolarisation in mice deep dorsal horn neurons in vitro.

Science.gov (United States)

Rivera-Arconada, Ivan; Lopez-Garcia, Jose A

2015-09-01

Spinal dorsal horn neurons constitute the first relay for pain processing and participate in the processing of other sensory, motor and autonomic information. At the cellular level, intrinsic excitability is a factor contributing to network function. In turn, excitability is set by the array of ionic conductance expressed by neurons. Here, we set out to characterise rebound depolarisation following hyperpolarisation, a feature frequently described in dorsal horn neurons but never addressed in depth. To this end, an in vitro preparation of the spinal cord from mice pups was used combined with whole-cell recordings in current and voltage clamp modes. Results show the expression of H- and/or T-type currents in a significant proportion of dorsal horn neurons. The expression of these currents determines the presence of rebound behaviour at the end of hyperpolarising pulses. T-type calcium currents were associated to high-amplitude rebounds usually involving high-frequency action potential firing. H-currents were associated to low-amplitude rebounds less prone to elicit firing or firing at lower frequencies. For a large proportion of neurons expressing both currents, the H-current constitutes a mechanism to ensure a faster response after hyperpolarisations, adjusting the latency of the rebound firing. We conclude that rebound depolarisation and firing are intrinsic factors to many dorsal horn neurons that may constitute a mechanism to integrate somatosensory information in the spinal cord, allowing for a rapid switch from inhibited-to-excited states.

Physical activity opportunities in Canadian childcare facilities: a provincial/territorial review of legislation.

Preschoolers spend a substantial portion of their day in childcare; therefore, these centers are an ideal venue to encourage healthy active behaviors. It is important that provinces'/territories' childcare legislation encourage physical activity (PA) opportunities. The purpose of this study was to review Canadian provincial/territorial childcare legislation regarding PA participation. Specifically, this review sought to 1) appraise each provincial/territorial childcare regulation for PA requirements, 2) compare such regulations with the NASPE PA guidelines, and 3) appraise these regulations regarding PA infrastructure. A review of all provincial/territorial childcare legislation was performed. Each document was reviewed separately by 2 researchers, and the PA regulations were coded and summarized. The specific provincial/territorial PA requirements (eg, type/frequency of activity) were compared with the NASPE guidelines. PA legislation for Canadian childcare facilities varies greatly. Eight of the thirteen provinces/territories provide PA recommendations; however, none provided specific time requirements for daily PA. All provinces/territories did require access to an outdoor play space. All Canadian provinces/territories lack specific PA guidelines for childcare facilities.

From the data on gamma-radiation dose rates, on meteorological data and conditions of atmospheric transfer at the first days following Chernobylsk NPP accident it was shown that soil contamination of Byelorussian and Russian territories with radionuclides was mainly caused by atmospheric precipitations on 28-30 April of 1986. Spatial distribution of radionuclide activity revealed that contamination of Russian territories were similar in isotopic content and radionuclide content considerably differed from contamination of Byelorussian territories

Habitat selection often involves choices made at different spatial scales, but the underlying mechanisms are still poorly understood, and studies that investigate the relative importance of individual scales are rare. We investigated the effect of three spatial scales (landscape, territory, nest-site) on the occurrence pattern of little crake Zapornia parva and water rail Rallus aquaticus at 74 ponds in the Masurian Lakeland, Poland. Habitat structure, food abundance and water chemical parameters were measured at nests and random points within landscape plots (from 300-m to 50-m radius), territory (14-m) and nest-site plots (3-m). Regression analyses suggested that the most relevant scale was territory level, followed by landscape, and finally by nest-site for both species. Variation partitioning confirmed this pattern for water rail, but also highlighted the importance of nest-site (the level explaining the highest share of unique variation) for little crake. The most important variables determining the occurrence of both species were water body fragmentation (landscape), vegetation density (territory) and water depth (at territory level for little crake, and at nest-site level for water rail). Finally, for both species multi-scale models including factors from different levels were more parsimonious than single-scale ones, i.e. habitat selection was likely a multi-scale process. The importance of particular spatial scales seemed more related to life-history traits than to the extent of the scales considered. In the case of our study species, the territory level was highly important likely because both rallids have to obtain all the resources they need (nest site, food and mates) in relatively small areas, the multi-purpose territories they defend.

2017-01-01

Full Text Available The current economic situation in rural territories is characterized by many challenges to their sustainable development. The level and quality of life in rural areas, underdevelopment of social infrastructure, the environmental situation significantly contributes to the depopulation of the rural territories. In this regard, it is very important to research and discuss the possible decision of problems of development of rural settlements.The actions of the state on formation of the complex of normative-legal documents regulating state policy in the field of rural development are aimed at ensuring the management of these areas by federal authorities which leads to some extent to resource dependence on it, and reduces the motivation of regional and municipal management to the formation of effective policy of rural development.The management of the regions chooses its directions of developing rural areas, without taking into account the prevailing socio-economic situation at the municipal level and features of development of rural settlements, which reduces the effectiveness of the management of the territory.As an example the authors have evaluated the level of rural areas development in Orel Region and proposed a classification of areas at regional level. The results of the research show that there could be three levels of rural territories development: highly stable, moderately stable and unstable areas. The main indicators of development of rural territories were selected as follows: incomes and expenses of budgets of rural areas, the volume of investments in fixed capital, average monthly nominal accrued wages of employees of enterprises and organizations, agricultural production in farms of all categories of the rural population. The authors have made some proposals as to how to solve the problems of instability in rural areas. The implementation of these decisions should happen on the background of permanent monitoring of the status and

Ultra-weak photon emission as a non-invasive tool for monitoring of oxidative processes in the epidermal cells of human skin: comparative study on the dorsal and the palm side of the hand.

All living organisms emit spontaneous ultra-weak photon emission as a result of cellular metabolic processes. Exposure of living organisms to exogenous factors results in oxidative processes and enhancement in ultra-weak photon emission. Here, hydrogen peroxide (H(2)O(2)), as a strongly oxidizing molecule, was used to induce oxidative processes and enhance ultra-weak photon emission in human hand skin. The presented work intends to compare both spontaneous and peroxide-induced ultra-weak photon emission from the epidermal cells on the dorsal and the palm side of the hand. A highly sensitive photomultiplier tube and a charge-coupled device camera were used to detect ultra-weak photon emission from human hand skin. Spontaneous ultra-weak photon emission from the epidermal cells on the dorsal side of the hand was 4 counts/s. Topical application of 500 mM H(2)O(2) to the dorsal side of the hand caused enhancement in ultra-weak photon emission to 40 counts/s. Interestingly, both spontaneous and peroxide-induced ultra-weak photon emission from the epidermal cells on the palm side of the hand were observed to increase twice their values, i.e. 8 and 80 counts/s, respectively. Similarly, the two-dimensional image of ultra-weak photon emission observed after topical application of H(2)O(2) to human skin reveals that photon emission from the palm side exceeds the photon emission from the dorsal side of the hand. The results presented indicate that the ultra-weak photon emission originating from the epidermal cells on the dorsal and the palm side of the hand is related to the histological structure of the human hand skin. Ultra-weak photon emission is shown as a non-destructive technique for monitoring of oxidative processes in the epidermal cells of the human hand skin and as a diagnostic tool for skin diseases.

Territory and nest site selection patterns by Grasshopper Sparrows in southeastern Arizona

Science.gov (United States)

Ruth, Janet M.; Skagen, Susan K.

2017-01-01

Grassland bird populations are showing some of the greatest rates of decline of any North American birds, prompting measures to protect and improve important habitat. We assessed how vegetation structure and composition, habitat features often targeted for management, affected territory and nest site selection by Grasshopper Sparrows (Ammodramus savannarum ammolegus) in southeastern Arizona. To identify features important to males establishing territories, we compared vegetation characteristics of known territories and random samples on 2 sites over 5 years. We examined habitat selection patterns of females by comparing characteristics of nest sites with territories over 3 years. Males selected territories in areas of sparser vegetation structure and more tall shrubs (>2 m) than random plots on the site with low shrub densities. Males did not select territories based on the proportion of exotic grasses. Females generally located nest sites in areas with lower small shrub (1–2 m tall) densities than territories overall when possible and preferentially selected native grasses for nest construction. Whether habitat selection was apparent depended upon the range of vegetation structure that was available. We identified an upper threshold above which grass structure seemed to be too high and dense for Grasshopper Sparrows. Our results suggest that some management that reduces vegetative structure may benefit this species in desert grasslands at the nest and territory scale. However, we did not assess initial male habitat selection at a broader landscape scale where their selection patterns may be different and could be influenced by vegetation density and structure outside the range of values sampled in this study.

Full Text Available Background Territory owners usually defeat intruders. One explanation for this observation is the uncorrelated asymmetry hypothesis which argues that contests might be settled by an arbitrary convention such as “owners win.” We studied the effect of territorial residency on contest asymmetries in the white-eared hummingbird (Hylocharis leucotis in a fir forest from central Mexico. Methods Twenty white-eared male adult hummingbird territories were monitored during a winter season, recording the territorial behavior of the resident against intruding hummingbirds. The size and quality of the territory were related to the probability that the resident would allow the use of flowers by the intruder. Various generalized models (logistical models were generated to describe the probabilities of victory for each individual resident depending on the different combinations of three predictor variables (territory size, territory quality, and intruder identity. Results In general, small and low quality territory owners tend to prevent conspecific intruders from foraging at a higher rate, while they frequently fail to exclude heterospecific intruders such as the magnificent hummingbird (Eugenes fulgens or the green violetear hummingbird (Colibri thalassinus on any territory size. Our results showed that the identity of the intruder and the size and quality of the territory determined the result of the contests, but not the intensity of defense.

1994-01-01

The central objective of this paper is to show how vertical restraints, which affect intra-brand competition, can and will be used as an effective mechanism for reducing inter-brand competition and increasing producer profits. We show how exclusive territories alter the perceived demand curve, making each producer believe he faces a less elastic demand curve, thereby inducing an increase of the equilibrium price. The use of exclusive territories may increase producers' profits, even if the pr...

Temporal binding function of dorsal CA1 is critical for declarative memory formation.

Temporal binding, the process that enables association between discontiguous stimuli in memory, and relational organization, a process that enables the flexibility of declarative memories, are both hippocampus-dependent and decline in aging. However, how these two processes are related in supporting declarative memory formation and how they are compromised in age-related memory loss remain hypothetical. We here identify a causal link between these two features of declarative memory: Temporal binding is a necessary condition for the relational organization of discontiguous events. We demonstrate that the formation of a relational memory is limited by the capability of temporal binding, which depends on dorsal (d)CA1 activity over time intervals and diminishes in aging. Conversely, relational representation is successful even in aged individuals when the demand on temporal binding is minimized, showing that relational/declarative memory per se is not impaired in aging. Thus, bridging temporal intervals by dCA1 activity is a critical foundation of relational representation, and a deterioration of this mechanism is responsible for the age-associated memory impairment.

Cross-border cooperation in inner Scandinavia: A territorial impact assessment

Medeiros, Eduardo, E-mail: emedeiros@campus.ul.pt

2017-01-15

The use of territorial impact assessment procedures is gaining increasing relevance in the European Union policy evaluation processes. However, no concrete territorial impact assessment tools have been applied to evaluating EU cross-border programmes. In this light, this article provides a pioneering analysis on how to make use of territorial impact assessment procedures on cross-border programmes. More specifically, it assesses the main territorial impacts of the Inner Scandinavian INTERREG-A sub-programme, in the last 20 years (1996–2016). It focuses on its impacts on reducing the barrier effect, in all its main dimensions, posed by the presence of the administrative border. The results indicate a quite positive impact of the analysed cross-border cooperation programme, in reducing the barrier effect in all its main dimensions. The obtained potential impact values for each analysed dimension indicate, however, that the ‘economy-technology’ dimension was particularly favoured, following its strategic intervention focus in stimulating the economic activity and the attractiveness of the border area. - Highlights: • A territorial impact assessment method to assess cross-border cooperation is proposed. • This method rationale is based on the main dimensions of the barrier effect. • This method identified positive impacts in all analysed dimensions. • The economy-technological dimension was the most positively impacted one.

1993-05-01

This paper reviews the historical evolution of environmental awareness over the last three decades. The aspects covered include: the growing economic interdependence of nations, the development of new technologies, the internationalization of human rights and the phenomenon of organized trans-nationalism. The paper then develops a framework of territorial development assessment criteria embodying the United Nation's approach towards sustainable growth in which the rights of the human individual to a healthy life in harmony with nature are placed at the forefront of all sustainable growth decision making. Examples of decisional processes during actual hearings to decide on the go-ahead of energy development projects in Italy (a district heating system and a combined cycle gas turbine power plant) are given to evidence optimum ways to have public participation and interaction with government and expert committees take place in line with the United Nation's approach towards development. An important element dealt with is how to optimize the dissemination and use of information

Ventral and Dorsal Striatum Networks in Obesity: Link to Food Craving and Weight Gain.

Science.gov (United States)

Contreras-Rodríguez, Oren; Martín-Pérez, Cristina; Vilar-López, Raquel; Verdejo-Garcia, Antonio

2017-05-01

The food addiction model proposes that obesity overlaps with addiction in terms of neurobiological alterations in the striatum and related clinical manifestations (i.e., craving and persistence of unhealthy habits). Therefore, we aimed to examine the functional connectivity of the striatum in excess-weight versus normal-weight subjects and to determine the extent of the association between striatum connectivity and individual differences in food craving and changes in body mass index (BMI). Forty-two excess-weight participants (BMI > 25) and 39 normal-weight participants enrolled in the study. Functional connectivity in the ventral and dorsal striatum was indicated by seed-based analyses on resting-state data. Food craving was indicated with subjective ratings of visual cues of high-calorie food. Changes in BMI between baseline and 12 weeks follow-up were assessed in 28 excess-weight participants. Measures of connectivity in the ventral striatum and dorsal striatum were compared between groups and correlated with craving and BMI change. Participants with excess weight displayed increased functional connectivity between the ventral striatum and the medial prefrontal and parietal cortices and between the dorsal striatum and the somatosensory cortex. Dorsal striatum connectivity correlated with food craving and predicted BMI gains. Obesity is linked to alterations in the functional connectivity of dorsal striatal networks relevant to food craving and weight gain. These neural alterations are associated with habit learning and thus compatible with the food addiction model of obesity. Copyright © 2016 Society of Biological Psychiatry. Published by Elsevier Inc.

Automatic phoneme category selectivity in the dorsal auditory stream.

Science.gov (United States)

Chevillet, Mark A; Jiang, Xiong; Rauschecker, Josef P; Riesenhuber, Maximilian

2013-03-20

Debates about motor theories of speech perception have recently been reignited by a burst of reports implicating premotor cortex (PMC) in speech perception. Often, however, these debates conflate perceptual and decision processes. Evidence that PMC activity correlates with task difficulty and subject performance suggests that PMC might be recruited, in certain cases, to facilitate category judgments about speech sounds (rather than speech perception, which involves decoding of sounds). However, it remains unclear whether PMC does, indeed, exhibit neural selectivity that is relevant for speech decisions. Further, it is unknown whether PMC activity in such cases reflects input via the dorsal or ventral auditory pathway, and whether PMC processing of speech is automatic or task-dependent. In a novel modified categorization paradigm, we presented human subjects with paired speech sounds from a phonetic continuum but diverted their attention from phoneme category using a challenging dichotic listening task. Using fMRI rapid adaptation to probe neural selectivity, we observed acoustic-phonetic selectivity in left anterior and left posterior auditory cortical regions. Conversely, we observed phoneme-category selectivity in left PMC that correlated with explicit phoneme-categorization performance measured after scanning, suggesting that PMC recruitment can account for performance on phoneme-categorization tasks. Structural equation modeling revealed connectivity from posterior, but not anterior, auditory cortex to PMC, suggesting a dorsal route for auditory input to PMC. Our results provide evidence for an account of speech processing in which the dorsal stream mediates automatic sensorimotor integration of speech and may be recruited to support speech decision tasks.

Two centuries of economic territorial dynamics: the case of France

Directory of Open Access Journals (Sweden)

Magali Talandier

2016-01-01

Full Text Available We propose an analysis of the socio-economic development processes at work in territories at the scale of French communes from 1806 to 2010. This is an extremely fine scale for such analysis, given that there are 36,000 communes in mainland France. The diachronic dimension, spanning two centuries, makes it possible to consider the temporal depth of territorial development. But the primary interest is not so much demographics as the socio-economic dimension of these variations over two centuries. We have analysed demographic changes as the expression of the socio-economic processes that shaped French territory over two centuries. Dynamic mapping of long-term population shifts reflects the industrial expansion of certain territories, decline due to the end of traditional farming practices, the shock produced by two world wars, the Fordist period and the post-war boom; the subsequent impact of an increasingly globalized, metropolitan economy then becomes apparent. We thus identify, map and analyse several historico-socio-economic phases.

2011-07-01

Full Text Available It is very important to be found methods to increase the competitiveness between the Romanian administrative-territorial units, under the current conditions of the economic crisis, by means of the existing economic levers successfully used within the European Union regions. The development regions of Romania do not have the statute of administrative units, but they represent territorial units large enough to constitute a good basis for the elaboration and implementation of regional development strategies, allowing an efficient use of the financial and human resources. The scope for which these development regions were created had in view the support granted for the larger communities in their action to settle the problems which go beyond the administrative borders and which surpass the financial possibilities of one county. In Romania, the communes, towns, municipalities and counties are defined as administrative-territorial units within which the local autonomy is exercised and the authorities of the local public administration are organized and operate. The local, communal, town, municipality and county councils, as deliberative authorities, and also the mayors and the presidents of county councils as executive authorities have the duties to solve the public matters of the community, acting as authorities of the Romanian public administration. In Romania, the local autonomy is only administrative and financial, having as objective the organization, operation, competencies and tasks, and also the management of the inland resources. The principle of the local financial autonomy implies the fact that the administrative-territorial units have the right to financial resources, which can be used by the authorities of the local public administration when exercising their tasks. According to the Law of the local public finances, the local budget incomes could be made also of the non-reimbursable funds granted by the European Union. Based on the

Full text: After collapse of the Soviet Union, the Republic of Kazakhstan has inherited a wealthy nuclear legacy from the former superpower. The Kazakhstan enterprises were actively engaged into a closed nuclear fuel cycle existing in the USSR. In addition, the Kazakhstan territory housed strategic nuclear forces defense bases, nuclear weapon test-sites, and research institutions engaged in studying and developing of nuclear technologies including these for defense and space purposes. After gaining its independence, the Republic of Kazakhstan made efforts to rid itself of many components of this system: military bases were closed; nuclear weapon was withdrawn from Kazakhstan territory; nuclear test-sites were closed; many fuel cycle enterprises having lost orders for their products had to reduce their output or close down; scientific and research institutions were re-oriented to perform operations in the field of peaceful nuclear and radiation technologies use. All these actions were not only appreciated by the international politics thus promoting the integration of the newly independent state into the international economy, but have also created the necessary prerequisites for qualitative change of the ecological conditions at Kazakhstan territory. However, there are negative consequences of an old political system collapse also. One of them is a significant reduction of control over nuclear and radioactive materials located at Kazakhstan territory. In the end of the last millennium and with the beginning of the new one, numerous radical terrorist organizations have livened up their activities. The situation arisen in Kazakhstan may be used by such organizations to acquire nuclear and radioactive materials for the purposes of terrorist acts and threats. It is likely that some organizations acquire such materials to sell to third parties or foreign terrorist organizations rather than use them in any acts within Kazakhstan. Due to structural reorganization of force

Commercial Territory Design for a Distribution Firm with New Constructive and Destructive Heuristics

Directory of Open Access Journals (Sweden)

Jaime

2012-02-01

Full Text Available A commercial territory design problem with compactness maximization criterion subject to territory balancing and connectivity is addressed. Four new heuristics based on Greedy Randomized Adaptive Search Procedures within a location-allocation scheme for this NP-hard combinatorial optimization problem are proposed. The first three (named GRLH1, GRLH2, and GRDL build the territories simultaneously. Their construction phase consists of two parts: a location phase where territory seeds are identified, and an allocation phase where the remaining basic units are iteratively assigned to a territory. In contrast, the other heuristic (named SLA builds the territories one at a time. Empirical results reveals that GRLH1 and GRLH2 find near-optimal or optimal solutions to relatively small instances, where exact solutions could be found. The proposed procedures are relatively fast. We carried out a comparison between the proposed heuristic procedures and the existing method in larger instances. It was observed the proposed heuristic GRLH1 produced competitive results with respect to the existing approach.

Decolonizing through integration: Australia's off-shore island territories

Roger Wettenhall

2016-11-01

Full Text Available Australia’s three small off-shore island territories – Norfolk Island in the Pacific Ocean and Christmas Island and the Cocos (Keeling Islands Group in the Indian Ocean – can be seen as monuments to 19th century British-style colonization, though their early paths to development took very different courses. Their transition to the status of external territories of the Australian Commonwealth in the 20th century – early in the case of Norfolk and later in the cases of Christmas and Cocos – put them on a common path in which serious tensions emerged between local populations which sought autonomous governance and the Commonwealth government which wanted to impose governmental systems similar to those applying to mainstream Australians. This article explores the issues involved, and seeks to relate the governmental history of the three island territories to the exploration of island jurisdictions developed in island studies research.

Cognitive behaviour therapy territory model: effective disputing approach.

Science.gov (United States)

Lam, D

1997-06-01

This paper proposes a disputing model (territory model) which is particularly useful and effective for disputing clients who persistently hold on to their dysfunctional thinking and/or core irrational beliefs. Their 'stubbornness' to change is compounded by unhealthy negative emotions during sessions. The intense emotion makes it difficult to access the belief system, and therefore any attempt to dispute it often proves futile. This model advocates the shift of disputing onto a different 'territory/ground' where the client can be facilitated to acquire higher, abstract and objective thinking, and at the same time his/her emotional level is susceptible to rational and logical arguments. The new thinking would act as a catalyst for the client to reflect on his/her dysfunctional thought/irrational beliefs. In this paper, the author uses a case example to illustrate and discuss the ineffectiveness of the 'traditional' way of disputing the dysfunctional thinking/core beliefs of a difficult and emotional client. This is contrasted with the 'territory' model.

Experience of rehabilitation of territories contaminated during Chernobyl NPP accident in Ukraine

Zeleznyak, M.

2003-01-01

Full text: Significant part of Ukraine territory, including agricultural lands, was subjected to radioactive contamination as a result of ChNPP emergency. In the initial period of emergency the main attention was given to averting of radioactivity propagation and irradiation of the population. Irradiation of the thyroid gland for a large contingent of human, especially children, became the hardest consequence of the emergency. The main problem of minimization of the emergency consequences consisted in a complete rehabilitation of contaminated areas. Resettlement of residents of contaminated territories was appeared effective only in cases, when expected effective dose of irradiation could exceed levels of interference. In the remote terms after emergency this measure was accompanied by an unjustifiable psychological stress for the population and considerable material expenses. The adopted organizational and technological countermeasures allowed to reduce significantly a dose of irradiation for thyroid gland, especially for population of Kiev urban agglomeration - about 4 mln. persons. The efficiency of countermeasures was insufficient due to hiding of the emergency firstly, and then because of the late announcement of a danger, after iodine attack already. The program of reconstruction of irradiation doses for different groups of population was realized, i.e. the liquidators of emergency, children, inhabitants of the contaminated zone. The sharp increase of thyroid gland cancer frequency and other types of pathologies was observed. The network of specialized medical entities for consulting and clinical examination of victims was created. Iodine radionuclides entered into human organism per os with foodstuffs predominantly. Prevention of milk contamination and its processing was the most effective measures of population protection. The big part of the territory of Ukraine was subjected to radioactive contamination with fallout predominantly the area of Ukrainian

Full Text Available At present a territory is considered as the basis for effective socio-economical development of the region. However, special attention should be paid to the presence of available resources on the territory under consideration, as well as the conditions of their future development. The availability and/or the possibility of creating/upgrading the existing resources encourage today the accumulated potential of the territory. Potential of the area is a set of capabilities and different levels of impact on the total potential of the area and includes such resources as natural, human, investment, innovation, employment, scientific and technological, demographic, urban development, tourism, tax, financial, recreational, marketing, cluster and infrastructure, as well as other kinds of potentials. The prospects for the development of enterprises or their complexes determine the capacities of the territory, the basis of their operation being the location. In this connection it is necessary to consider the basic types of potential undertakings, which the article refer to: marketing, investment, innovation, employment, tax, industrial, economic, resources. For more exact information and accurate prediction each primary resource must include a group of elements. The number of analyzed resources, as well as their elements, is not limited. However an obligatory demand for including the resources or their elements in the list is their exceptional importance for the development of the subject. For efficient operation of enterprises or their complexes in a certain area it is necessary to identify the sources of coordinated development of land and property of the complex, the purpose of which is to obtain maximum benefit from the combination of "territory↔enterprise (s". For this aim we suggest assessing the possibility of long-term development according to the following scenario: establishment of a list of core resources, having impact on businesses

Active surveillance is important in infection control programmes, allowing the detection of patients colonised with multi-drug resistant organisms and preventing the spread of multi-drug resistant organisms. The aim of this study was to determine the rate of asymptomatic colonisation with multi-drug resistant organisms and the prevalence of each organism in patients transferred to An-Najah National University Hospital, Nablus, occupied Palestinian territory. Patients transferred from other hospitals between January and December, 2015, were screened at time of admission by taking nasal, groin, and axillary swabs. Swabs were cultured and assessed for the presence of multi-drug resistant organisms (extended spectrum β-lactamase producers, Pseudomonas aeroginosae, Acinetobacter baumannii, methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococcus, and carbapenem-resistant enterobacteriaceae. Of the 822 screened patients, 265 (32%) had infections with multi-drug resistant organisms. 394 isolates of multi-drug resistant organisms were obtained: 131 (33%) isolates were extended spectrum β-lactamase producers, 119 (30%) isolates were P aeroginosae, 26 (9%) isolates were A baumannii, 94 (24%) isolates were methicillin-resistant S aureus, 13 (3%) isolates were vancomycin-resistant enterococci, and one (<1%) isolate was carbapenem-resistant enterobacteriaceae. We identified a high prevalence of asymptomatic colonisation with multidrug-resistant bacteria in transferred patients. These findings emphasise the need for a national strategy to combat the spread of multi-drug resistant organisms in the occupied Palestinian territory. An-Najah National University.

Towards the observation of Territorial Energy Systems - a geographical design approach for energy territorialisation

International Nuclear Information System (INIS)

Flety, Yann

2014-01-01

Having an effect on a system calls for a thorough knowledge of it. The main goal of this research is to provide a general framework for the interpretation of geographic information, as well as a methodological framework to understand the interrelations between territory and energy in the context of a territorial observatory. A literature review of energy planning on the one hand and spatial planning on the other reveals similar developments in the two fields, in particular in terms of decentralisation and environmental concerns. The change of geographical scale chosen for the analysis brings new possibilities for public intervention. In this context, therefore, local authorities have a key role to play in implementing energy policy goals in their planning practices. They need analysis and prospective studies, as well as basic knowledge to carry out territorial energy planning. Indeed, the socio-spatial functions (living, travelling, working, etc.) are themselves at the root of spatial layout, urban forms and settlement structures. Those functions cannot be disassociated from questions of land use and energy. So, to understand energy which is vital, ubiquitous, and responsible for the organisation of territory, a systemic approach is proposed: the Territorial Energy System. It illustrates the importance of the interactions between a territory and its energy system, and more precisely, the interdependence between energy processes and territorial ones. We propose a design approach in the context of an observatory, and more precisely conceptual models, to analyse the territory-energy interrelations, especially with a focus on semantic dimensions. This approach combines three elements: a meta-model, a light and pre-consensus domain ontology, and individual conceptual data models for each indicator. An original indicator is then used for a first ontology population: the territorial energy label. Characterising the interrelations between territory and energy is non

During early meiotic prophase, a nucleus-wide reorganization leads to sorting of chromosomes into homologous pairs and to establishing associations between homologous chromosomes along their entire lengths. Here, we investigate global features of chromosome organization during this process, using a chromosome painting method in whole-mount Caenorhabditis elegans gonads that enables visualization of whole chromosomes along their entire lengths in the context of preserved 3D nuclear architecture. First, we show that neither spatial proximity of premeiotic chromosome territories nor chromosome-specific timing is a major factor driving homolog pairing. Second, we show that synaptonemal complex-independent associations can support full lengthwise juxtaposition of homologous chromosomes. Third, we reveal a prominent elongation of chromosome territories during meiotic prophase that initiates prior to homolog association and alignment. Mutant analysis indicates that chromosome movement mediated by association of chromosome pairing centers (PCs) with mobile patches of the nuclear envelope (NE)-spanning SUN-1/ZYG-12 protein complexes is not the primary driver of territory elongation. Moreover, we identify new roles for the X chromosome PC (X-PC) and X-PC binding protein HIM-8 in promoting elongation of X chromosome territories, separable from their role(s) in mediating local stabilization of pairing and association of X chromosomes with mobile SUN-1/ZYG-12 patches. Further, we present evidence that HIM-8 functions both at and outside of PCs to mediate chromosome territory elongation. These and other data support a model in which synapsis-independent elongation of chromosome territories, driven by PC binding proteins, enables lengthwise juxtaposition of chromosomes, thereby facilitating assessment of their suitability as potential pairing partners.

An amphioxus Msx gene expressed predominantly in the dorsal neural tube.

Sharman, A C; Shimeld, S M; Holland, P W

1999-04-01

Genomic and cDNA clones of an Msx class homeobox gene were isolated from amphioxus (Branchiostoma floridae). The gene, AmphiMsx, is expressed in the neural plate from late gastrulation; in later embryos it is expressed in dorsal cells of the neural tube, excluding anterior and posterior regions, in an irregular reiterated pattern. There is transient expression in dorsal cells within somites, reminiscent of migrating neural crest cells of vertebrates. In larvae, mRNA is detected in two patches of anterior ectoderm proposed to be placodes. Evolutionary analyses show there is little phylogenetic information in Msx protein sequences; however, it is likely that duplication of Msx genes occurred in the vertebrate lineage.

Territoriality, prospecting, and dispersal in cooperatively breeding Micronesian Kingfishers (Todiramphus cinnamominus reichenbachii)

We investigated territoriality, prospecting, and dispersal behavior in cooperatively breeding Pohnpei Micronesian Kingfishers (Todiramphus cinnamominus reichenbachii) throughout the annual cycle using radiotelemetry and color-band resights. Mean home-range size was 6.3 ha and territories were 8.1 ha. Within territories, Micronesian Kingfishers shared 63% of their home-range space with coterritorial occupants, and 3% was shared with extraterritorial conspecifics. Birds on cooperative territories had larger home ranges that overlapped more with coterritory occupants' home ranges than birds in pair-held territories. Despite evidence suggesting that resources necessary for survival and reproduction occurred on each territory, Micronesian Kingfishers of all age and sex classes made extraterritorial prospecting movements. Prospecting was rare; it comprised only 4.3% of our observations. When birds departed on forays, they were gone for ∼1.9 h and returned to home territories before sunset. Prospecting by dominant birds was temporally correlated with courtship and nest initiation, and birds were observed at neighboring nest sites with opposite-sex conspecifics during the period when females were available for fertilization. Juveniles and helpers prospected throughout the year and made repeated homesteading movements to dispersal destinations before dispersing. Mean dispersal distance for radiomarked individuals was 849 m. Results suggest that prospecting in Micronesian Kingfishers is a complex behavior that provides information for dispersal decisions and familiarity with dispersal destinations. Additionally, extraterritorial movements may provide covert opportunities for reproduction, which have potential to profoundly influence the distribution of fitness among helper and dominant Micronesian Kingfishers.

The Northern Goshawk (Accipiter gentilis) is the largest of the three North American species ofAccipiter and is more closely associated with older forests than are the other species. Its reliance on older forests has resulted in concerns about its status, extensive research into its habitat relationships, and litigation. Our objective was to model the spatial patterns of goshawk territories in the Black Hills, South Dakota, to make inferences about the underlying processes. We used a modification of Ripley's K function that accounts for inhomogeneous intensity to determine whether territoriality or habitat determined the spacing of goshawks in the Black Hills, finding that habitat conditions rather than territoriality were the determining factor. A spatial model incorporating basal area of trees in a stand of forest, canopy cover, age of trees >23 cm in diameter, number of trees per hectare, and geographic coordinates provided good fit to the spatial patterns of territories. There was no indication of repulsion at close distances that would imply spacing was determined by territoriality. These findings contrast with those for the Kaibab Plateau, Arizona, where territoriality is an important limiting factor. Forest stands where the goshawk nested historically are now younger and have trees of smaller diameter, probably having been modified by logging, fire, and insects. These results have important implications for the goshawk's ecology in the Black Hills with respect to mortality, competition, forest fragmentation, and nest-territory protection.

Acupuncture is shown to be effective in producing analgesia in ankle sprain pain in humans and animals. To examine the underlying mechanisms of the acupuncture-induced analgesia, the effects of electroacupuncture (EA) on weight-bearing forces (WBR) of the affected foot and dorsal horn neuron activities were examined in a rat model of ankle sprain. Ankle sprain was induced manually by overextending ligaments of the left ankle in the rat. Dorsal horn neuron responses to ankle movements or compression were recorded from the lumbar spinal cord using an in vivo extracellular single unit recording setup 1 day after ankle sprain. EA was applied to the SI-6 acupoint on the right forelimb (contralateral to the sprained ankle) by trains of electrical pulses (10 Hz, 1-ms pulse width, 2-mA intensity) for 30 min. After EA, WBR of the sprained foot significantly recovered and dorsal horn neuron activities were significantly suppressed in ankle-sprained rats. However, EA produced no effect in normal rats. The inhibitory effect of EA on hyperactivities of dorsal horn neurons of ankle-sprained rats was blocked by the α-adrenoceptor antagonist phentolamine (5 mg/kg ip) but not by the opioid receptor antagonist naltrexone (10 mg/kg ip). These data suggest that EA-induced analgesia in ankle sprain pain is mediated mainly by suppressing dorsal horn neuron activities through α-adrenergic descending inhibitory systems at the spinal level.

Spiny Prey, Fortunate Prey. Dorsal Spines Are an Asset in Intraguild Interactions among Lady Beetles

2017-11-01

Full Text Available The Multicolored Asian Ladybird, Harmonia axyridis, is an extremely successful invasive species. Here we suggest that, in addition to many other traits, the dorsal spines of its larvae contribute to their success, as suggested by behavioral observations of agonistic interactions between H. axyridis and European coccinellids. In coccinellids, the role of dorsal spines in these interactions has been poorly studied and they could be a physical protection against intraguild predators. Dorsal spines of second instar H. axyridis larvae were removed with micro-scissors, which resulted in spineless larvae after molting (spineless group. These larvae were then exposed to starved Coccinella septempunctata larvae. Two control categories were also submitted to interactions: H. axyridis larvae with all their spines (control group and with their spines, but injured by pin stings (injured group. Spine removal at the second instar did not hamper H. axyridis development. The bite rate by C. septempunctata was significantly higher on the spineless H. axyridis and more dorsally located compared to the control and injured groups, while no bite rate difference was observed between the injured and the control group. Our results suggest that in addition to behavioral and chemical defenses, the dorsal spines play a significant protective role against bites. Therefore, spines in ladybirds could be considered as a morphological defense against intraguild predation. In H. axyridis, these defenses might contribute to its success in food resources already exploited by other guild members and thus further facilitate the invasion of new areas.

Raclopride or high-frequency stimulation of the subthalamic nucleus stops cocaine-induced motor stereotypy and restores related alterations in prefrontal basal ganglia circuits.

Motor stereotypy is a key symptom of various neurological or neuropsychiatric disorders. Neuroleptics or the promising treatment using deep brain stimulation stops stereotypies but the mechanisms underlying their actions are unclear. In rat, motor stereotypies are linked to an imbalance between prefrontal and sensorimotor cortico-basal ganglia circuits. Indeed, cortico-nigral transmission was reduced in the prefrontal but not sensorimotor basal ganglia circuits and dopamine and acetylcholine release was altered in the prefrontal but not sensorimotor territory of the dorsal striatum. Furthermore, cholinergic transmission in the prefrontal territory of the dorsal striatum plays a crucial role in the arrest of motor stereotypy. Here we found that, as previously observed for raclopride, high-frequency stimulation of the subthalamic nucleus (HFS STN) rapidly stopped cocaine-induced motor stereotypies in rat. Importantly, raclopride and HFS STN exerted a strong effect on cocaine-induced alterations in prefrontal basal ganglia circuits. Raclopride restored the cholinergic transmission in the prefrontal territory of the dorsal striatum and the cortico-nigral information transmissions in the prefrontal basal ganglia circuits. HFS STN also restored the N-methyl-d-aspartic-acid-evoked release of acetylcholine and dopamine in the prefrontal territory of the dorsal striatum. However, in contrast to raclopride, HFS STN did not restore the cortico-substantia nigra pars reticulata transmissions but exerted strong inhibitory and excitatory effects on neuronal activity in the prefrontal subdivision of the substantia nigra pars reticulata. Thus, both raclopride and HFS STN stop cocaine-induced motor stereotypy, but exert different effects on the related alterations in the prefrontal basal ganglia circuits. © 2012 The Authors.

The dopamine system has been characterized in motor function, goal-directed behaviors, and rewards. Recent studies recognize various dopamine system genes as being associated with autism spectrum disorder (ASD). However, how dopamine system dysfunction induces ASD pathophysiology remains unknown. In the present study, we demonstrated that mice with increased dopamine functions in the dorsal striatum via the suppression of dopamine transporter expression in substantia nigra neurons or the optogenetic stimulation of the nigro-striatal circuitry exhibited sociability deficits and repetitive behaviors relevant to ASD pathology in animal models, while these behavioral changes were blocked by a D1 receptor antagonist. Pharmacological activation of D1 dopamine receptors in normal mice or the genetic knockout (KO) of D2 dopamine receptors also produced typical autistic-like behaviors. Moreover, the siRNA-mediated inhibition of D2 dopamine receptors in the dorsal striatum was sufficient to replicate autistic-like phenotypes in D2 KO mice. Intervention of D1 dopamine receptor functions or the signaling pathways-related D1 receptors in D2 KO mice produced anti-autistic effects. Together, our results indicate that increased dopamine function in the dorsal striatum promotes autistic-like behaviors and that the dorsal striatum is the neural correlate of ASD core symptoms.

Full Text Available Nation States have three defining characteristics: government of a territory, rapport with a group of people and ownership of a sovereign power. All three of these characteristics are undergoing changes. Several developments involve a redefinition of the “State” and produce numerous contradictions, which can only be solved if we consider the historicity of both the phenomenal essence and the conceptual essence of the State. We need to rethink and reconceptualise the State within the context of the new tendencies and transformations delineated by globalisation.

In this context, the spatial planning practice modifies the territorial structure, involving solid strategic development activities through three main ways – identifying the local politics and defining the investment projects, as well as the correlation of activities with the right compentences of the interested parties and actors. The regional interdependences are more and more complex and dynamic and require the permanent constitution of networks, the cooperation and integration of different regions of the European Union at all relevant territorial levels.

The organization of honeybee ocelli: Regional specializations and rhabdom arrangements.

Science.gov (United States)

Ribi, Willi; Warrant, Eric; Zeil, Jochen

2011-11-01

We have re-investigated the organization of ocelli in honeybee workers and drones. Ocellar lenses are divided into a dorsal and a ventral part by a cusp-shaped indentation. The retina is also divided, with a ventral retina looking skywards and a dorsal retina looking at the horizon. The focal plane of lenses lies behind the retina in lateral ocelli, but within the dorsal retina in the median ocellus of both workers and drones. Ventral retinula cells are ca. 25μm long with dense screening pigments. Dorsal retinula cells are ca. 60μm long with sparse pigmentation mainly restricted to their proximal parts. Pairs of retinula cells form flat, non-twisting rhabdom sheets with elongated, straight, rectangular cross-sections, on average 8.7μm long and 1μm wide. Honeybee ocellar rhabdoms have shorter and straighter cross-sections than those recently described in the night-active bee Megalopta genalis. Across the retina, rhabdoms form a fan-shaped pattern of orientations. In each ocellus, ventral and dorsal retinula cell axons project into two separate neuropils, converging on few large neurons in the dorsal, and on many small neurons in the ventral neuropil. The divided nature of the ocelli, together with the particular construction and arrangement of rhabdoms, suggest that ocelli are not only involved in attitude control, but might also provide skylight polarization compass information.

Spatial Aggregation of Forest Songbird Territories and Possible Implications for Area Sensitivity

Directory of Open Access Journals (Sweden)

Julie Bourque

2006-06-01

Full Text Available Habitat area requirements of forest songbirds vary greatly among species, but the causes of this variation are not well understood. Large area requirements could result from advantages for certain species when settling their territories near those of conspecifics. This phenomenon would result in spatial aggregations much larger than single territories. Species that aggregate their territories could show reduced population viability in highly fragmented forests, since remnant patches may remain unoccupied if they are too small to accommodate several territories. The objectives of this study were twofold: (1 to seek evidence of territory clusters of forest birds at various spatial scales, lags of 250-550 m, before and after controlling for habitat spatial patterns; and (2 to measure the relationship between spatial autocorrelation and apparent landscape sensitivity for these species. In analyses that ignored spatial variation of vegetation within remnant forest patches, nine of the 17 species studied significantly aggregated their territories within patches. After controlling for forest vegetation, the locations of eight out of 17 species remained significantly clustered. The aggregative pattern that we observed may, thus, be indicative of a widespread phenomenon in songbird populations. Furthermore, there was a tendency for species associated with higher forest cover to be more spatially aggregated [ERRATUM].

2005-12-01

Questions of assessment of earthquake economical losses on urban territories of Uzbekistan, taking into account damage forming factors, which are increqasing or reducing economical losses were discussed in the paper. Buildings and facilities vulnerability factors were classified. From total value (equal to 50) were selected most important ones. Factors ranging by level of impact and weight function in loss assessment were ranged. One group of damage forming factors includs seismic hazard assessment, design, construction and maintenance of building and facilities. Other one is formed by city planning characteristics and includes : density of constructions and population, area of soft soils, existence of liquefaction susceptible soils and etc. To all these factors has been given weight functions and interval values by groups. Methodical recomendations for loss asessment taking into account above mentioned factors were developed. It gives possibility to carry out preventive measures for protection of vulnerable territories, to differentiate cost assessment of each region in relation with territory peculiarity and damage value. Using developed method we have ranged cities by risk level. It has allowed to establish ratings of the general vulnerability of urban territories of cities and on their basis to make optimum decisions, oriented to loss mitigation and increase of safety of population. Besides the technique can be used by insurance companies for estimated zoning of territory, development of effective utilization schema of land resources, rational town-planning, an economic estimation of used territory for supply with information of the various works connected to an estimation of seismic hazard. Further improvement of technique of establishment of rating of cities by level of damage from earthquakes will allow to increase quality of construction, rationality of accommodation of buildings, will be an economic stimulator for increasing of seismic resistance of

The development of neuroimaging has allowed clinicians to improve clinico-anatomic correlations in patients with strokes. Brainstem and cerebellum structures are well delineated on MRI, but there is a lack of standardization in their arterial supply. We present a system of 12 brainstem and cerebellum axial sections, depicting the dominant arterial territories and the most important anatomic structures. These sections may be used as a practical tool to determine arterial territories on MRI, and may help establish consistent clinico-anatomic correlations in patients with brainstem and cerebellar ischemic strokes.

Thus, an important condition of industrial structure development is the formation of innovative landscape representing the entirety of innovative territorial subjects that use innovative technologies, management tools for creation the product. In narrow sense, innovative landscape can be understood as an integrative entirety of parameters including socio-economic conditions, state administrative body, innovative economic subjects, existence of innovative infrastructure and cluster interactions etc. A methodic approach to comparative estimation of industrial regions innovative landscape parameters considered in the article lets identify its state and structural characteristics with the purpose of making more reasonable decisions on productive forces location and o n the increase of innovativeness level of industrial territories and regions.

Consistent left-right asymmetry cannot be established by late organizers in Xenopus unless the late organizer is a conjoined twin.

How embryos consistently orient asymmetries of the left-right (LR) axis is an intriguing question, as no macroscopic environmental cues reliably distinguish left from right. Especially unclear are the events coordinating LR patterning with the establishment of the dorsoventral (DV) axes and midline determination in early embryos. In frog embryos, consistent physiological and molecular asymmetries manifest by the second cell cleavage; however, models based on extracellular fluid flow at the node predict correct de novo asymmetry orientation during neurulation. We addressed these issues in Xenopus embryos by manipulating the timing and location of dorsal organizer induction: the primary dorsal organizer was ablated by UV irradiation, and a new organizer was induced at various locations, either early, by mechanical rotation, or late, by injection of lithium chloride (at 32 cells) or of the transcription factor XSiamois (which functions after mid-blastula transition). These embryos were then analyzed for the position of three asymmetric organs. Whereas organizers rescued before cleavage properly oriented the LR axis 90% of the time, organizers induced in any position at any time after the 32-cell stage exhibited randomized laterality. Late organizers were unable to correctly orient the LR axis even when placed back in their endogenous location. Strikingly, conjoined twins produced by late induction of ectopic organizers did have normal asymmetry. These data reveal that although correct LR orientation must occur no later than early cleavage stages in singleton embryos, a novel instructive influence from an early organizer can impose normal asymmetry upon late organizers in the same cell field.

Do hair-crested drongos reduce prospective territory competition by dismantling their nest after breeding?

Lv, Lei; Li, Jianqiang; Kingma, Sjouke A.; Gao, Chang; Wang, Yong; Komdeur, Jan; Zhang, Zhengwang

Animals that breed seasonally often use the same territory where they successfully produced young previously. Intra-specific competition may be intense for these high-quality territories, and therefore, natural selection should favour behaviour of territory owners to reduce such competition.

Regulations concerning land use density controls in non-urban areas are often ineffective in protecting the rural character of such areas, within the context of Colombia's territorial organization plans What they tend to do is indirectly promote urban expansion through the fixing of minimum plot sizes Rather than question the methods employed in land use classification, the present study uses the case of the rural area of Santa Elena on the outskirts of Medellin and the existing zoning controls as established in the territorial organization plan, and focuses on the regulations established for each land use category as they effect occupation densities and patterns of plot fragmentation. On the one hand a simulation is undertaken of the trends which would result from land occupation in accordance with existing regulations concerning land use classification and plot size This indicates that the overall effect would be to disperse settlement patterns and fragment the landscape Secondly, an alternative scenario is developed based on the modification of minimum plot sizes for each of the three land use classifications established in the existing plan (protection, rural and suburban) In this way, and through the perspective of landscape ecology, It Is shown that in certain cases less dispersion and greater concentration of settlements can be achieved, and in other cases dispersion is minimized The use of GIS is fundamental in the development of such simulation techniques

Elaboration of methods for assessment of radio-ecological safety state of objects, situated on the territories contaminated with Chernobyl radionuclides

2008-01-01

The main purpose of assessment of radio-ecological state of object is to elaborate recommendations to reduce both radiation dose and negative action of other contaminators on human organism. The basis of objects' ecological safety assessment is considering complex influence of multiple negative factors, such as radioactive contamination, firstly, and air, water, soil and noise pollution, secondly. The objects of assessments are social, industrial, rural enterprises and their production: school buildings and territories, all kinds of recreational institutions, civil buildings, etc. The described method is embodied in a computer program, which enables calculation of integral indicator of contamination and gives information about object's safety state. The results of the work may be proposed to the corresponding supervisor institutions as a prototype of practical guidance to control ecological state of the objects and territories. Particularly, the proposed methods are necessary to determine the order of measures, normally undertaken to deactivate objects, and to provide unified approach to radio-ecological safety assessment of objects, situated in the territories contaminated with Chernobyl radionuclides.

Retinal glia promote dorsal root ganglion axon regeneration.

Directory of Open Access Journals (Sweden)

Barbara Lorber

Full Text Available Axon regeneration in the adult central nervous system (CNS is limited by several factors including a lack of neurotrophic support. Recent studies have shown that glia from the adult rat CNS, specifically retinal astrocytes and Müller glia, can promote regeneration of retinal ganglion cell axons. In the present study we investigated whether retinal glia also exert a growth promoting effect outside the visual system. We found that retinal glial conditioned medium significantly enhanced neurite growth and branching of adult rat dorsal root ganglion neurons (DRG in culture. Furthermore, transplantation of retinal glia significantly enhanced regeneration of DRG axons past the dorsal root entry zone after root crush in adult rats. To identify the factors that mediate the growth promoting effects of retinal glia, mass spectrometric analysis of retinal glial conditioned medium was performed. Apolipoprotein E and secreted protein acidic and rich in cysteine (SPARC were found to be present in high abundance, a finding further confirmed by western blotting. Inhibition of Apolipoprotein E and SPARC significantly reduced the neuritogenic effects of retinal glial conditioned medium on DRG in culture, suggesting that Apolipoprotein E and SPARC are the major mediators of this regenerative response.

The dorsolateral calcaneocuboid ligaments have different configurations. In the literature they are only described as either the dorsal or lateral calcaneocuboid ligament. However, recent reconstructive surgical techniques may benefit from a better understanding of the anatomy. The aims of this study were to classify the morphology and attachments of the dorso-lateral calcaneocuboid ligaments and to determine their dimensions. The dorso-lateral aspects of the calcaneocuboid joint of 30 cadaver feet were dissected to expose the associated ligaments. Further, we evaluated possible bony landmarks of the calcaneus that could imply which shape or course the ligament would have in a specific individual. Our findings showed a wide variety of configurations in shape, number, and attachment sites. A constant dorsal ligament and an additional narrower lateral ligament was detectable in half of the cases. The majority of the dorso-lateral calcaneocuboid ligament-complex had an upward course and fanning out from proximal to distal. No bony predictor for the ligaments' shape or course was found. The dorso-lateral ligament-complex of the calcaneocuboid joint revealed a wide variety of configurations. Better understanding of the anatomy of these ligaments may aid in the anatomic reconstruction of these ligaments.

Full Text Available In the context of global criticism on urban sprawl, the questions which arises are: what can we do with the expansion forms already occurred in most part of our cities; can they be fully or partially integrated into the city? But first, which exactly are the common morphological features of urban expansion areas in large European cities, and (by comparison in Romania? The urban form correlated to these „sparwl patterns” and „sprawl mechanisms” shows more then the lack of planning, but a social input in occuping the territory, related with a specific meaning of the landscape. The paper explores the relationship between the five distinct morphological patterns ways of forming in relation to spatial and landscape shapes which they generate, in the territories of sprawl, all illustrated through case studies of Bucharest.

OBJECTIVES. To illustrate the history and the evolution over time of bulbar dorsal onlay urethroplasty, comparing outcomes when using buccal mucosa or skin grafts. MATERIALS AND METHODS. Ninety-four patients underwent bulbar urethral reconstruction using two dorsal onlay techniques, namely augmented anastomotic urethroplasty and dorsal onlay graft urethroplasty. Preoperative evaluation included clinical history, physical examination, urine culture, residual urine measurement, uroflowmetry and urethrography. Thirty-four patients underwent augmented anastomotic urethroplasty using penile skin (10 cases) or buccal mucosa (24 cases) grafts. Sixty patients underwent dorsal onlay graft urethroplasty using penile skin (38 cases) or buccal mucosa (22 cases) grafts. Forty-eight out of 94 patients received skin grafts and 46 buccal mucosal grafts. RESULTS. Sixty-four (68%) out of 94 cases were successful, whereas 30 (32%) failed. The 34 augmented anastomotic urethroplasties provided successful outcomes in 24 cases (70.6%), but poor outcomes in 10 (29.4%) cases. The 60 dorsal onlay graft urethroplasty proved to be successful in 42 cases (70%), failing in 18 (30%) cases. Twenty-eight (58.3%) out of 48 penile skin grafts were successful and 20 (41.7%) failed. Thirty-six (78.3%) out of 46 buccal mucosa grafts were successful and 10 (21.7%) failed. The 30 failed cases were then treated with internal urethrotomy in 14 cases (46.7%), perineal urethrostomy in 8 cases (26.7%), two-stage repair in 4 cases (13.3%), and one-stage repair in 4 cases (13.3%). CONCLUSIONS. The dorsal onlay technique used for bulbar urethral stricture repair has changed over time. In our experience, the buccal mucosa seems to be the best substitute graft material for bulbar urethroplasty using dorsal approach.

Day-to-day variability in performance is a common experience. We investigated its neural correlate by studying learning behavior of monkeys in a two-alternative forced choice task, the two-armed bandit task. We found substantial session-to-session variability in the monkeys' learning behavior. Recording the activity of single dorsal putamen neurons we uncovered a dual function of this structure. It has been previously shown that a population of neurons in the DLP exhibits firing activity sensitive to the reward value of chosen actions. Here, we identify putative medium spiny neurons in the dorsal putamen that are cue-selective and whose activity builds up with learning. Remarkably we show that session-to-session changes in the size of this population and in the intensity with which this population encodes cue-selectivity is correlated with session-to-session changes in the ability to learn the task. Moreover, at the population level, dorsal putamen activity in the very beginning of the session is correlated with the performance at the end of the session, thus predicting whether the monkey will have a "good" or "bad" learning day. These results provide important insights on the neural basis of inter-temporal performance variability.

Directory of Open Access Journals (Sweden)

N. I. Romanenkova

2011-01-01

Full Text Available Abstract. The degree of immunity to polioviruses of three serotypes among children of different ages was analysed on certain "controlled" and "silent" territories of Russia in different periods of Polio Eradication Initiative. It was shown that the levels of immunity of children’s population to polioviruses on "controlled" and "silent" territories had no significant difference. It was stated that on the phase which preceded the certification for the absence of circulation of wild polioviruses, when the National Immunisation Days were conducted in the country, the percentage of eronegative children to polioviruses of different serotypes was low on all the territories of Russia. After Russia as a part of the WHO European region was certified as a polio free country and mass immunisation was stopped thepercentage of seronegative children increased, especially to poliovirus of serotype 3, both on the "controlled" and on the "silent" territories.

Javier A. Cienfuegos

Full Text Available Background: Agenesis of the dorsal pancreas is a rare malformation. Since 1911 and until 2008, 53 cases have been reported. Several authors have recently described the association of this anomaly with neoplasia of the ventral pancreas, thus we performed a systematic review of the literature from 2008 to 2015. Methods: A systematic review of the Medline and ISI Web of Science Databases from 2008 until 2015 was carried out, and 30 articles which met the inclusion criteria were identified that included a total of 53 patients: 7 children and 46 adults. Conclusions: Although dorsal pancreatic agenesis is a rare malformation, given its association with non-alcoholic pancreatitis and neoplasia of the residual pancreas, physicians should maintain an expectant attitude.

2017-12-01

Full Text Available The article contains information on methods of geoecological zoning carried out based on the assessment of cartographic material using geoinformation technologies for the analysis of factographic cartographic material. The proposed methodology complements the existing methodological recommendations on geological and environmental research, developed by VSEGINGEO. The paper reflects the basic principles of obtaining the initial environmental information for creation of a map evaluation model of the Salekhard Area, and the rationale for selecting factors and numerical criteria for an integrated environmental assessment of the territory, taking into account the specifics of nature-technogenic conditions of the Severnoye Priobye region (West Siberia. The article briefly describes the main natural factors of the region of research, including landscape, geological, radiation, engineering-geological, geocryological, hydrogeological factors. Separate block describes the objects of technogenic load, including technogeneally-transformed landscapes in residential areas, corridors of transport communications, industrial and energy zones, and local ecologically significant objects. Ecological significance of natural and technogenic factors affected conducted ranking of their numerical parameters of the evaluation criteria. The article shows the application of a method of expert scoring for obtaining an integral assessment of the ecological state of the geological environment and creating a map of the regionalization of the Salekhard Area. Based on obtained cartographic model, a brief analysis of the existing ecological situation in the Salekhard Area shows the territories of favorable, satisfactory, tense, and crisis ecological states. The geoinformation-integrated model serves as the basis for determination of ecologically significant factors at the points of mapping the state of the geological environment, which allows for the further development of the

Features of the territorial planning of the sea coastal zone

Full Text Available The coastal zone in Ukraine is likely to undergo the most profound change in the near future. Already more than 65 percent of the Ukrainian Black Sea region population lives within 30 km of the coast. Consequently, unless territory planning and careful environmental management are instituted, sharp conflicts over coastal space and resource are likely, and the degradation of natural resources will stop future social-economic development. In order to maintain and restore coastal ecosystem it was implemented law about formation of the national ecological network of Ukraine. Later were developed General Scheme for Planning of the Territory of Ukraine and regional level planning scheme but there is no especial document regulating the use of land in the coastal zone. The study of geographical conditions, economic activity, and population resettlement shows separation within the regions of several echelons of economic development in relation to the coastline. Such separation may be based on differences in intensity and types of economic use within the territory and the water area, as well as the population density on the land. These features include the following economic stripes: seaside-facade, middle, peripheral – on land, and coastal, territorial waters, exclusive economic zone – in the direction of the sea. At the same time, each economic stripe has a complex internal structure. There are several basic principles of functional zoning of the territory highlighted in the article can help to rational plan the seaside regions.

Propagation of a dorsal cortical fracture of the third metacarpal bone in two horses

Seemingly, propagation of a dorsal cortical fracture in the third metacarpal bone developed after continued race performance in 2 horses. Historically, both horses had intermittent lameness that had responded to nonsteroidal anti-inflammatory drugs and brief rest periods. However, lameness in both horses had increased in severity. Radiography revealed a dorsal cortical fracture of the third metacarpal bone, with propagation of the fracture plane proximally. Fractures were incomplete and healed with stall rest in both horses

We examined home range behavior of female feral pigs (Sus scrofa) in a heavily hunted population on Fort Benning Military Reservation in west-central Georgia, USA. We used Global Positioning System location data from 24 individuals representing 18 sounders (i.e., F social groups) combined with markrecapture and camera-trap data to evaluate evidence of territorial behavior at the individual and sounder levels. Through a manipulative experiment, we examined evidence for an inverse relationship between population density and home range size that would be expected for territorial animals. Pigs from the same sounder had extensive home range overlap and did not have exclusive core areas. Sounders had nearly exclusive home ranges and had completely exclusive core areas, suggesting that female feral pigs on Fort Benning were territorial at the sounder level but not at the individual level. Lethal removal maintained stable densities of pigs in our treatment area, whereas density increased in our control area; territory size in the 2 areas was weakly and inversely related to density of pigs. Territorial behavior in feral pigs could influence population density by limiting access to reproductive space. Removal strategies that 1) match distribution of removal efforts to distribution of territories, 2) remove entire sounders instead of individuals, and 3) focus efforts where high-quality food resources strongly influence territorial behaviors may be best for long-term control of feral pigs.

Birth Territory: a theory for midwifery practice.

Science.gov (United States)

Fahy, Kathleen M; Parratt, Jenny Anne

2006-07-01

The theory of Birth Territory describes, explains and predicts the relationships between the environment of the individual birth room, issues of power and control, and the way the woman experiences labour physiologically and emotionally. The theory was synthesised inductively from empirical data generated by the authors in their roles as midwives and researchers. It takes a critical post-structural feminist perspective and expands on some of the ideas of Michel Foucault. Theory synthesis was also informed by current research about the embodied self and the authors' scholarship in the fields of midwifery, human biology, sociology and psychology. In order to demonstrate the significance of the theory, it is applied to two clinical stories that both occur in hospital but are otherwise different. This analysis supports the central proposition that when midwives use 'midwifery guardianship' to create and maintain the ideal Birth Territory then the woman is most likely to give birth naturally, be satisfied with the experience and adapt with ease in the post-birth period. These benefits together with the reduction in medical interventions also benefit the baby. In addition, a positive Birth Territory is posited to have a broader impact on the woman's partner, family and society in general.

Chromosome Painting Reveals Asynaptic Full Alignment of Homologs and HIM-8–Dependent Remodeling of X Chromosome Territories during Caenorhabditis elegans Meiosis

Nabeshima, Kentaro; Mlynarczyk-Evans, Susanna; Villeneuve, Anne M.

2011-01-01

During early meiotic prophase, a nucleus-wide reorganization leads to sorting of chromosomes into homologous pairs and to establishing associations between homologous chromosomes along their entire lengths. Here, we investigate global features of chromosome organization during this process, using a chromosome painting method in whole-mount Caenorhabditis elegans gonads that enables visualization of whole chromosomes along their entire lengths in the context of preserved 3D nuclear architecture. First, we show that neither spatial proximity of premeiotic chromosome territories nor chromosome-specific timing is a major factor driving homolog pairing. Second, we show that synaptonemal complex-independent associations can support full lengthwise juxtaposition of homologous chromosomes. Third, we reveal a prominent elongation of chromosome territories during meiotic prophase that initiates prior to homolog association and alignment. Mutant analysis indicates that chromosome movement mediated by association of chromosome pairing centers (PCs) with mobile patches of the nuclear envelope (NE)–spanning SUN-1/ZYG-12 protein complexes is not the primary driver of territory elongation. Moreover, we identify new roles for the X chromosome PC (X-PC) and X-PC binding protein HIM-8 in promoting elongation of X chromosome territories, separable from their role(s) in mediating local stabilization of pairing and association of X chromosomes with mobile SUN-1/ZYG-12 patches. Further, we present evidence that HIM-8 functions both at and outside of PCs to mediate chromosome territory elongation. These and other data support a model in which synapsis-independent elongation of chromosome territories, driven by PC binding proteins, enables lengthwise juxtaposition of chromosomes, thereby facilitating assessment of their suitability as potential pairing partners.

Floral anatomy of Delphinieae (Ranunculaceae: comparing flower organization and vascular patterns

Directory of Open Access Journals (Sweden)

Andrew V. Novikoff

2014-04-01

Full Text Available Species of the tribe Delphinieae have dorsoventralized flowers; their pentamerous calyx and reduced corolla are dorsally spurred and inner spurs are nectariferous. Based on this common floral scheme, Delphinieae species exhibit a wide diversity of floral structures and morphologies. We present here the first investigation of the floral anatomy in Delphinieae. The organization of the floral vascular system has been studied in species representative of the floral morphological diversity of Delphinieae: Aconitum lasiocarpum, Delphinium elatum, and Consolida regalis. The three species show a similar vascularization of the calyx and of the reproductive organs, but exhibit distinct anatomical features in the corolla where the nectaries are borne. The sepals and the stamens have a trilacunar three-traced and a unilacunar one-traced vascularization, respectively. Three free carpels in D. elatum and A. lasiocarpum are basically supplied by six vascular bundles – three independent dorsal bundles and three fused lateral bundles. In C. regalis the single carpel is supplied by three independent vascular bundles (one dorsal and two ventral. Staminodes are not vascularized. The basic type of petal vascularization is unilacunar one-traced, but in the case of C. regalis the derived bilacunar two-traced type has been observed. This latter state arose as a result of the fusion of the two dorsal petal primordia. The results of this first comparative study of the floral anatomy of Delphinieae are discussed with the recent phylogenetic, morphological, and evo-devo findings concerning the tribe.

The spinal dorsal horn comprises heterogeneous populations of interneurons and projection neurons, which form neuronal circuits crucial for processing of primary sensory information. Although electrophysiological analyses have uncovered sensory stimulation-evoked neuronal activity of various spinal dorsal horn neurons, monitoring these activities from large ensembles of neurons is needed to obtain a comprehensive view of the spinal dorsal horn circuitry. In the present study, we established in vivo calcium imaging of multiple spinal dorsal horn neurons by using a two-photon microscope and extracted three-dimensional neuronal activity maps of these neurons in response to cutaneous sensory stimulation. For calcium imaging, a fluorescence resonance energy transfer (FRET)-based calcium indicator protein, Yellow Cameleon, which is insensitive to motion artifacts of living animals was introduced into spinal dorsal horn neurons by in utero electroporation. In vivo calcium imaging following pinch, brush, and heat stimulation suggests that laminar distribution of sensory stimulation-evoked neuronal activity in the spinal dorsal horn largely corresponds to that of primary afferent inputs. In addition, cutaneous pinch stimulation elicited activities of neurons in the spinal cord at least until 2 spinal segments away from the central projection field of primary sensory neurons responsible for the stimulated skin point. These results provide a clue to understand neuronal processing of sensory information in the spinal dorsal horn.

2015-08-30

Major depressive disorder is associated with lower medial prefrontal cortex volumes. The role that gender might play in moderating this relationship and what particular medial prefrontal cortex subregion(s) might be implicated is unclear. Magnetic resonance imaging was used to assess dorsal, ventral, and anterior cingulate regions of the medial prefrontal cortex in a normative sample of male and female adults. The Depression, Anxiety, and Stress Scale (DASS) was used to measure these three variables. Voxel-based morphometry was used to test for correlations between medial prefrontal gray matter volume and depressive traits. The dorsal medial frontal cortex was correlated with greater levels of depression, but not anxiety and stress. Gender moderates this effect: in males greater levels of depression were associated with lower dorsal medial prefrontal volumes, but in females no relationship was observed. The results indicate that even within a non-clinical sample, male participants with higher levels of depressive traits tend to have lower levels of gray matter volume in the dorsal medial prefrontal cortex. Our finding is consistent with low dorsal medial prefrontal volume contributing to the development of depression in males. Future longitudinal work is needed to substantiate this possibility.

2012-01-01

In this review,we describe the current models of dorsal and ventral streams in vision,audition and touch.Available theories take their first steps from the model of Milner and Goodale,which was developed to explain how human actions can be efficiently carried out using visual information.Since then,similar concepts have also been applied to other sensory modalities.We propose that advances in the knowledge of brain functioning can be achieved through models explaining action and perception patterns independently from sensory modalities.

Body size correlates with fertilization success but not gonad size in grass goby territorial males.

Directory of Open Access Journals (Sweden)

Jose Martin Pujolar

Full Text Available In fish species with alternative male mating tactics, sperm competition typically occurs when small males that are unsuccessful in direct contests steal fertilization opportunities from large dominant males. In the grass goby Zosterisessor ophiocephalus, large territorial males defend and court females from nest sites, while small sneaker males obtain matings by sneaking into nests. Parentage assignment of 688 eggs from 8 different nests sampled in the 2003-2004 breeding season revealed a high level of sperm competition. Fertilization success of territorial males was very high but in all nests sneakers also contributed to the progeny. In territorial males, fertilization success correlated positively with male body size. Gonadal investment was explored in a sample of 126 grass gobies collected during the period 1995-1996 in the same area (61 territorial males and 65 sneakers. Correlation between body weight and testis weight was positive and significant for sneaker males, while correlation was virtually equal to zero in territorial males. That body size in territorial males is correlated with fertilization success but not gonad size suggests that males allocate much more energy into growth and relatively little into sperm production once the needed size to become territorial is attained. The increased paternity of larger territorial males might be due to a more effective defense of the nest in comparison with smaller territorial males.

Full Text Available Habitat use by the Little Blue Heron (Egretta caerulea and discovery of feeding territoriality are discussed here. The results showed the existence of a territorial individual defending an area (2,564.46 ± 943.56 m² close to the mangrove, and non-territorial individuals (9.17 ± 2.54 in the rest of a demarcated area (mean area for the non-territorial: 893.25 ± 676.72. A weak positive correlation (r = 0.47, df = 46, p < 0.05 was found between the overlapping of territorial and non-territorial individuals (2.85 ± 3.07 m² and the mean overlapped area for territorial individuals (171.41 ± 131.40 m². Higher capture (1.52 ± 1.14 × 1.00 ± 1.37 catches/minutes and success rates (0.45 ± 0.31 × 0.21 ± 0.27 and lower energy expenditure rates (45.21 ± 14.96 × 51.22 ± 14.37 steps/minutes; and 3.65 ± 2.55 × 4.94 ± 3.28 stabs/minutes were observed for individuals foraging in areas close to the mangrove. The results suggest that the observed territorial behaviour is more related to a number of food parameters than to intruder pressure, and also that the observed territoriality might be related to defense of areas with higher prey availability.

Lasting Differential Effects on Plasticity Induced by Prenatal Stress in Dorsal and Ventral Hippocampus

2016-01-01

Full Text Available Early life adversaries have a profound impact on the developing brain structure and functions that persist long after the original traumatic experience has vanished. One of the extensively studied brain structures in relation to early life stress has been the hippocampus because of its unique association with cognitive processes of the brain. While the entire hippocampus shares the same intrinsic organization, it assumes different functions in its dorsal and ventral sectors (DH and VH, resp., based on different connectivity with other brain structures. In the present review, we summarize the differences between DH and VH and discuss functional and structural effects of prenatal stress in the two sectors, with the realization that much is yet to be explored in understanding the opposite reactivity of the DH and VH to stressful stimulation.

Catalina Larach-del Castillo

2017-06-01

Full Text Available The tension in the distribution of power, with particular regards to the centralization and decentralization techniques, commonly impedes a coherent association between territorial realities and national demands, and could even encourage peripheral and separatist resistances. In spite of different resources available in the States, it is possible to query whether policies jointly executed by distinct levels of government are a sufficient illustration of inter-territorial interaction. This paper examines the unitary and federal models from an interterritorial perspective, with the purpose of finding common grounds, as well as mechanisms that will encourage concerted efforts and actions.

Dorsal approaches to intradural extramedullary tumors of the craniovertebral junction

Directory of Open Access Journals (Sweden)

D Refai

2010-01-01

Full Text Available Tumors of the craniovertebral junction (CVJ pose significant challenges to cranial and spine surgeons. Familiarity with the complex anatomy and avoidance of injury to neurologic and vascular structures are essential to success. Multiple surgical approaches to address lesions at the CVJ have been promoted, including ventral and dorsal-based trajectories. However, optimal selection of the surgical vector to manage the pathology requires a firm understanding of the limitations and advantages of each approach. The selection of the best surgical trajectory must include several factors, such as obtaining the optimal exposure of the region of interest, avoiding injury to critical neurologic or vascular structures, identification of normal anatomical landmarks, the familiarity and comfort level of the surgeon to the approach, and the need for fixation. This review article focuses on dorsal approaches to the CVJ and the advantages and limitations in managing intradural extramedullary tumors.

Full Text Available Georgia can be characterised by its turbulent history, centuries-old traditions, and a great ethnic diversity. This makes it necessary to include historical determinants, in addition to geopolitical and economic factors, when making a regional analysis of its territory and contemporary governance issues. Five stages of the development of the present territorial division of Georgia are distinguished. They have been identified by means of an analysis of key events (critical junctures of significance in the formation of its historical regions. Additionally, their influence at each of the three levels of the current territorial division of independent Georgia is discussed, in particular in the context of territorial governance.

Single-prolonged stress induces apoptosis in dorsal raphe nucleus in the rat model of posttraumatic stress disorder

Directory of Open Access Journals (Sweden)

Liu Dongjuan

2012-11-01

Full Text Available Abstract Introduction Post-traumatic stress disorder (PTSD is an anxiety disorder that develops after exposure to a life-threatening traumatic experience. Meta-analyses of the brainstem showed that midsagittal area of the pons was significantly reduced in patients with PTSD, suggesting a potential apoptosis in dorsal raphe nucleus after single-prolonged stress (SPS. The aim of this study is to investigate whether SPS induces apoptosis in dorsal raphe nucleus in PTSD rats, which may be a possible mechanism of reduced volume of pons and density of gray matter. Methods In this study, rats were randomly divided into 1d, 7d and 14d groups after SPS along with the control group. The apoptosis rate was determined using annexin V-FITC/PI double-labeled flow cytometry (FCM. Levels of Cytochrome c (Cyt-C was examined by Western blotting. Expression of Cyt-C on mitochondria in the dorsal raphe nucleus neuron was determined by enzymohistochemistry under transmission electron microscopy (TEM. The change of thiamine monophosphatase (TMP levels was assessed by enzymohistochemistry under light microscope and TEM. Morphological changes of the ultrastructure of the dorsal raphe nucleus neuron were determined by TEM. Results Apoptotic morphological alterations were observed in dorsal raphe nucleus neuron for all SPS-stimulate groups of rats. The apoptosis rates were significantly increased in dorsal raphe nucleus neuron of SPS rats, along with increased release of cytochrome c from the mitochondria into the cytoplasm, increased expression of Cyt-C and TMP levels in the cytoplasm, which reached to the peak of increase 7 days of SPS. Conclusions The results indicate that SPS induced Cyt-C released from mitochondria into cytosol and apoptosis in dorsal raphe nucleus neuron of rats. Increased TMP in cytoplasm facilitated the clearance of apoptotic cells. We propose that this presents one of the mechanisms that lead to reduced volume of pons and gray matter associated

The immune and nervous systems are two major organ systems responsible for host defense and memory. Both systems achieve memory and learning that can be retained, retrieved, and utilized for decades. Here, we report the surprising discovery that peripheral sensory neurons of the dorsal root ganglia (DRGs) of immunized mice contain antigen-specific antibodies. Using a combination of rigorous molecular genetic analyses, transgenic mice, and adoptive transfer experiments, we demonstrate that DRGs do not synthesize these antigen-specific antibodies, but rather sequester primarily IgG1 subtype antibodies. As revealed by RNA-seq and targeted quantitative PCR (qPCR), dorsal root ganglion (DRG) sensory neurons harvested from either naïve or immunized mice lack enzymes (i.e., RAG1, RAG2, AID, or UNG) required for generating antibody diversity and, therefore, cannot make antibodies. Additionally, transgenic mice that express a reporter fluorescent protein under the control of Igγ1 constant region fail to express Ighg1 transcripts in DRG sensory neurons. Furthermore, neural sequestration of antibodies occurs in mice rendered deficient in neuronal Rag2, but antibody sequestration is not observed in DRG sensory neurons isolated from mice that lack mature B cells [e.g., Rag1 knock out (KO) or μMT mice]. Finally, adoptive transfer of Rag1-deficient bone marrow (BM) into wild-type (WT) mice or WT BM into Rag1 KO mice revealed that antibody sequestration was observed in DRG sensory neurons of chimeric mice with WT BM but not with Rag1-deficient BM. Together, these results indicate that DRG sensory neurons sequester and retain antigen-specific antibodies released by antibody-secreting plasma cells. Coupling this work with previous studies implicating DRG sensory neurons in regulating antigen trafficking during immunization raises the interesting possibility that the nervous system collaborates with the immune system to regulate antigen-mediated responses.

Inflammatory reaction of the anterior dorsal tongue presumably to sodium lauryl sulfate within toothpastes: a triple case report.

Science.gov (United States)

Brown, Ronald S; Smith, Langston; Glascoe, Alison L

2018-02-01

Sodium lauryl sulfate (SLS), a popular surface active agent ingredient within toothpastes, is known for its foaming action. Surface active agents increase the effectiveness of toothpastes with respect to dental plaque removal. SLS is a known irritant and also has allergenic potential. The authors report 3 patients with oral pain secondary to inflammation of the dorsal anterior tongue. These patients were all using toothpastes with SLS as an ingredient. The dorsal tongue lesions and oral pain resolved upon switching to toothpastes without SLS as an ingredient. Clinicians should be aware of the potential of SLS within toothpastes to cause oral mucosal inflammatory reactions of the anterior dorsal tongue. To our knowledge, these are the first case reports of oral mucosal inflammatory reactions of the anterior dorsal tongue associated with SLS containing toothpastes. Copyright © 2017 Elsevier Inc.

Replication labeling patterns and chromosome territories typical of mammalian nuclei are conserved in the early metazoan Hydra.

Science.gov (United States)

Alexandrova, Olga; Solovei, Irina; Cremer, Thomas; David, Charles N

2003-12-01

To investigate the evolutionary conservation of higher order nuclear architecture previously described for mammalian cells we have analyzed the nuclear architecture of the simple polyp Hydra. These diploblastic organisms have large nuclei (8-10 microm) containing about 3x10(9) bp of DNA organized in 15 chromosome pairs. They belong to the earliest metazoan phylum and are separated from mammals by at least 600 million years. Single and double pulse labeling with halogenated nucleotides (bromodeoxyuridine, iododeoxyuridine and chlorodeoxyuridine) revealed striking similarities to the known sequence of replication labeling patterns in mammalian nuclei. These patterns reflect a persistent nuclear arrangement of early, mid-, and late replicating chromatin foci that could be identified during all stages of interphase over at least 5-10 cell generations. Segregation of labeled chromatids led after several cell divisions to nuclei with single or a few labeled chromosome territories. In such nuclei distinct clusters of labeled chromatin foci were separated by extended nuclear areas with non-labeled chromatin, which is typical of a territorial arrangement of interphase chromosomes. Our results indicate the conservation of fundamental features of higher order chromatin arrangements throughout the evolution of metazoan animals and suggest the existence of conserved mechanism(s) controlling this architecture.

The polymorphic, multilayered and networked urbanised territory

Nielsen, Tom

2015-01-01

The discussion of the network city has in recent years been supplemented by an increasing interest in reconsidering the notion of territory. Looking into both geographical and urban design theories, we find examples of a focus on how the networks of the city not only connect them irreversibly...... with sites and systems without any direct physical relation, but also of how this does not necessarily result in complete fragmentation and dissociation between the parts and the surrounding landscapes, as described in network city theory. By relating examples from this literature to a description...... in theory. The concept of The Polymorphic, Multilayered and Networked Urbanised Territory is introduced to grasp the reality experienced in European regions outside the largest and most potent versions of contemporary cities....

We present a new case of trombosis of the superficial dorsal penis vein called Penile Mondor's disease. The characteristics of the disease are reviewed and the most usual diagnostic and therapeutic methods. The case of a 41 year old man is reviewed who consulted for pain and induration on the proximal part of the penis. After phisical examination and Eco-doppler was made the diagnosis of Mondor's disease. He receibed treatment with non steroidal antiinflamatories and antibiotics. The dorsal vein thrombosis is a rare disease with pain an induration of the dorsal part of the penis. The ethiology can be traumatic, neoplasic, excesive sexual activity or abstinence. Is necesary the diferencial diagnosis with esclerosant linphangitis and the most important imaging is the Eco-doppler. The treatment is based in non steroidal antiinflamatories and antibiotics wit infection. The local aplication of heparine can be useful and the surgery with thrombectomy and resection is for persistent cases.

Structure transformations of endocrine system organs during adaptation to increased radioactivity

International Nuclear Information System (INIS)

Ermakova, O.V.

2004-01-01

It is well known that during ecological monitoring of contaminated territories registration of early abnormalities in an organism is hampered by man-caused influence of habitat. Under these circumstances study of both structural and functional changes in organs and tissues of rodents inhabiting radioactive contaminated territories is of great importance. Study of structural features of endocrine glands, hormones of which trigger the process of active adaptive changes in an organism, is very important in radioecological surveys. Basing on long-term study of voles we have determined that long-term living by rodents on the territories characterized by increased natural and artificial radioactivity (radium contaminated fields in the Komi Republic and 30-km zone of Chernobyl APS) substantially influences morpho-functional state of endocrine system organs, causing quantitative and qualitative changes. It is demonstrated that population processes modify biological consequences of small doze chronic ionizing radiation in habitat. We noticed the following: high heterogeneity of histological changes of thyroid gland and adrenal gland as a response to radioactive habitat contamination; disorder of interconnection among different links of endocrine system; dependence of radiation effects on gender, age, degree and character of radiation contamination of a habitat as well as duration of radioactive influence. We have got data on morphological characteristics of thyroid gland and adrenal gland during different phases of population amount of this kind of rodents. It was discovered that effectiveness of radiation influence is not the same during different periods of population cycle. Presence of voles on the territories characterized by increased radioactivity causes chronic tension of adrenal cortex (increasing of the organ mass, enlarging of thickness of zona fasciculata and zona reticularis). Destructive-necrotic processes combine with manifestation of reparative regeneration

When animals encounter conflict they initiate and escalate aggression to establish and maintain a social hierarchy. The neural mechanisms by which animals resolve fighting behaviors to determine such social hierarchies remain unknown. We identified two subregions of the dorsal habenula (dHb) in zebrafish that antagonistically regulate the outcome of conflict. The losing experience reduced neural transmission in the lateral subregion of dHb (dHbL)-dorsal/intermediate interpeduncular nucleus (d/iIPN) circuit. Silencing of the dHbL or medial subregion of dHb (dHbM) caused a stronger predisposition to lose or win a fight, respectively. These results demonstrate that the dHbL and dHbM comprise a dual control system for conflict resolution of social aggression. Copyright © 2016, American Association for the Advancement of Science.

Aposematism and crypsis are not enough to explain dorsal polymorphism in the Iberian adder

2017-11-01

Aposematic organisms can show phenotypic variability across their distributional ranges. The ecological advantages of this variability have been scarcely studied in vipers. We explored this issue in Vipera seoanei, a species that exhibits five geographically structured dorsal colour phenotypes across Northern Iberia: two zigzag patterned (Classic and Cantabrica), one dorsal-strip patterned (Bilineata), one even grey (Uniform), and one melanistic (Melanistic). We compared predation rates (raptors and mammals) on plasticine models resembling each colour phenotype in three localities. Visual modelling techniques were used to infer detectability (i.e. conspicuousness) of each model type for visually guided predators (i.e. diurnal raptors). We hypothesize that predation rates will be lower for the two zigzag models (aposematism hypothesis) and that models with higher detectability would show higher predation rates (detectability hypothesis). Classic and Bilineata models were the most conspicuous, while Cantabrica and Uniform were the less. Melanistic presented an intermediate conspicuousness. Predation rate was low (3.24% of models) although there was variation in attack frequency among models. Zigzag models were scarcely predated supporting the aposematic role of the zigzag pattern in European vipers to reduce predation (aposematism hypothesis). From the non-zigzag models, high predation occurred on Bilineata and Melanistic models, and low on Uniform models, partially supporting our detectability hypothesis. These results suggest particular evolutionary advantages for non-zigzag phenotypes such as better performance of Melanistic phenotypes in cold environments or better crypsis of Uniform phenotypes. Polymorphism in V. seoanei may respond to a complex number of forces acting differentially across an environmental gradient.

Offshore wind energy development in France and Germany: what role for territories? Final dissertation

International Nuclear Information System (INIS)

Douteau, Anne-Laure

2010-01-01

'Pays du Bessin au Virois' is a French association of cities. The association is concerned by projects of offshore wind farms. It wants to think about the consequences of the offshore wind farms on the territory, and the integration in the local activities. For that reason the association wanted to learn from the German experience of offshore development. To compare the French and the German situation, this report raises the question of the relationship between an offshore wind farm and a territory. Thanks to the characteristics of an offshore wind farm and of a territory, I built a method to analyze the relationship between a park and a territory. I studied two cases: the French territory Pays du Bessin au Virois related to the three projects of offshore wind parks in the Baie de Seine, and the German territory Ostfriesland, close to the first offshore wind park in Germany, Alpha Ventus. The two cases showed that important topics could be studied for every territory. There are differences between French and German situation. However the comparison sets on interesting actions for the Pays du Bessin au Virois. Another comparison can be realized with Denmark or United Kingdom, which offshore strategy is closer to the French situation. (author) [fr

Full Text Available The article is aimed at studying the mechanisms for activating the integration of territorial communities through the formation and use of social capital. The relevance of the study of administrative and territorial reforms based on the integration of the territorial communities from the perspective of the formation and use of social capital has been disclosed. The results of decentralization of power have been analyzed, and the advantages and disadvantages of this process have been highlighted. On the basis of studying publications on the indicated issue, the essence of the concepts of «community» and «territorial community» has been defined, their constituents and relationships with social capital have been disclosed. The article proposes application of an integrated estimation based on the method of expert estimations, which allows for the determination of the socio-economic performance of a single territorial community (STC, comparison of the activities by territorial communities and their integrations in the region, as well as the desirability of creating a STC. Prospect for further research is an analysis of the directions of institutional change, which facilitate the implementation of mechanisms for the effective development of social capital of both the territorial communities and the STC.

Comparison of dorsal and dorsomedial displacement in evaluation of first ray hypermobility in feet with and without hallux valgus.

Science.gov (United States)

Singh, Dishan; Biz, Carlo; Corradin, Marco; Favero, Laura

2016-06-01

Hypermobility of the first ray, a probable primary cause of hallux valgus, has traditionally been evaluated in the dorsal direction only although the first tarso-metatarsal joint allows movement in a dorso-medial direction. 600 feet, divided according to the presence or absence of hallux valgus, were evaluated for both dorsal and dorso-medial displacement using a Klaue device. In the control group, the mean first ray displacement was 7.2mm (4.2-11.3) in the dorsal direction (sagittal plane) and 8.3mm (4.0-12.6) in the 45° dorso-medial direction. In the hallux valgus group, the mean first ray mobility was 9.8mm (5.2-14.1) in the dorsal direction compared to a mean of 11.0mm (5.9-16.2) in the 45° dorso-medial direction. It is a paradox that hypermobility of the first ray is measured in only a dorsal (vertical) direction whereas a hallux valgus angle and an intermetatarsal angle are only measured in a transverse plane. Furthermore, the weightbearing foot pronates during gait and the first metatarsal is displaced in a dorsomedial direction rather than a pure dorsal direction. It is suggested that measurement hypermobility of the first ray at a 45° dorso-medial direction is more appropriate. Copyright © 2015 European Foot and Ankle Society. Published by Elsevier Ltd.

Galland, Daniel; Elinbaum, Pablo

2015-01-01

This paper argues that spatial planning systems tend to redefine and reinterpret conventional territorial scales through the dual adoption and articulation of legal instruments and spatial strategies at different levels of planning administration. In depicting such redefinition, this paper delves...... into the cases of Denmark and Catalonia through an analysis concerned with: i) the strategic spatial role attributed to each level of planning; and ii) the redefinition of territorial scales as a result of changing political objectives and spatial relationships occurring between planning levels. The assessment...... pertaining to the strategic roles of spatial planning instruments as well as the evolving redefinition of territorial scales in both Denmark and Catalonia suggests that the conventional, hierarchical ‘cascade-shaped’ ideal of policy implementation is superseded. While both cases tend to converge...

Our results show that part of the DRP is generated by a TTX-resistant, probably non-spiking micro-circuit with separate components mediated by GABA and glutamate....

In eukaryotes, microRNAs (miRNAs) serve as regulators of many biological processes, including virus infection. An miRNA can generally target diverse genes during virus-host interactions. However, the regulation of gene expression by multiple miRNAs has not yet been extensively explored during virus infection. This study found that the Spaztle (Spz)-Toll-Dorsal-antilipopolysaccharide factor (ALF) signaling pathway plays a very important role in antiviral immunity against invasion of white spot syndrome virus (WSSV) in shrimp ( Marsupenaeus japonicus ). Dorsal , the central gene in the Toll pathway, was targeted by two viral miRNAs (WSSV-miR-N13 and WSSV-miR-N23) during WSSV infection. The regulation of Dorsal expression by viral miRNAs suppressed the Spz-Toll-Dorsal-ALF signaling pathway in shrimp in vivo , leading to virus infection. Our study contributes novel insights into the viral miRNA-mediated Toll signaling pathway during the virus-host interaction.
