Resumen

Spatial layout optimization is a core of existing barracks renewal. Distinguishing from new built barracks, existing barrack spatial layout optimization needs to pay more attention to solve the contradiction between current and future. So in this chapter, we develop six primary design keys applied to existing barracks including harmony relations between barrack and its surrounding environment, emphasis on weakness construction, optimize allocation, improve security defense capabilities, enhance artistry of spatial layout and realize the whole structure optimization. Reference to ancient classical fortification thoughts and current construction conditions, we also explore 5 tactics to optimize existing barracks spatial layout , namely, function integration method, node co-ordinate method, axis control method, three-dimensional space construction method, as well as idle land reuse method. Finally, we choose one tipical case to integrated apply the above keys and tactics from theoretical and practical fields promoting the sustainable development of existing barrack .

Resumen

"The hay barrack and other hay structures from the Land of Maramureș The hay barrack is a unique structure, consisting of four wooden poles which support a pyramidal roof, which can be raised or lowered, depending on the amount of hay sheltered from the weather. The Land of Maramureș (the northern half of the current Maramureș County), a quite well-known traditional life stronghold, can be considered ”the World’s hay capital”, a place where the hay culture is stronger than anywhere else and where the fields are filled up with ”classic” hay barracks (we estimate that there are probably 10-15,000 structures still left), with tens of thousands hay stacks, with thousands hay barracks with immovable roof and with countless drying hayracks of different types, so many that they change the look of the landscape. Moreover, there is the only place where the hay barracks are still used today exactly as in the Middle Ages (being filled regularly, manually, with traditionally harvested hay), and on a huge scale, not found elsewhere. With prehistoric origins, the most special structure, the hay barrack is considered to have its birthplace in the Netherlands, from where, since the 13th and 14th centuries, it spread over a large part of the continent, a territory bordered by Great Britain, France, Northern Italy, Croatia, Hungary, Northern Transylvania, Ukraine, Russia or Scandinavia. Today, everywhere, the unusual barrack has disappeared, except în Maramureș and the Netherlands - where there is the second largest group of preserved structures, but without being used anymore for storing hay. The study lists the main features of the construction, the villages where the hay barracks survive in more significant number, and it tries to find out the reason why this type of structure still persists so strongly in that region. At the end there are some old images from different places, as well as contemporary photographs taken in Maramureș, featuring various types of hay structures. Keywords: hay barrack, hay stack, hayrack, Maramureș, traditional farming "

Resumen

Tidal range energy is one of the most predictable and reliable sources of renewable energy. This study’s main aim is to determine potential sites for tidal range power in East Malaysia, by analyzing tidal range distributions and resources and the feasibility of constructing barrages. Investigation was conducted in 34 sites, estimating their potential energy outputs and studying their areas for constructing barrages. Only 18 sites were marked as appropriate for constructing a tidal range energy extraction barrage. The highest potential power was found in Tanjung Manis, and its maximum capacity was calculated as 50.7kW. The second highest potential of tidal power extraction was found in Kuching Barrage at Pending, where an energy harvester could produce electric power up to 33.1kW.

Resumen

Unitary pallido-nigral synaptic currents were measured using optogenetic stimulation, which activated up to three unitary synaptic inputs to each substantia nigra pars reticulata (SNr) cell. Episodic barrages of synaptic conductances were generated based on in vivo firing patterns of globus pallidus pars externa (GPe) cells and applied to SNr cells using conductance clamp. Barrage inputs were compared to continuous step conductances with the same mean. Barrage inputs and steps both slowed SNr neuron firing and produced disinhibition responses seen in peristimulus histograms. Barrages were less effective than steps at producing inhibition and disinhibition responses. Barrages, but not steps, produced irregular firing during the inhibitory response. Phase models of SNr neurons were constructed from their phase-resetting curves. The phase models reproduced the inhibition and disinhibition responses to the same inputs applied to the neurons. The disinhibition response did not require rebound currents but arose from reset of the cells’ oscillation. The differences in firing rate and irregularity in response to barrage and step inhibition resulted from the high sensitivity of SNr neurons to inhibition at late phases in their intrinsic oscillation. During step inhibition, cells continued rhythmic firing at a reduced rate. During barrages, brief bouts of intense inhibition stalled the cells’ phase evolution late in their cycle, close to firing, and even very brief respites from inhibition rapidly released single action potentials. The SNr cell firing pattern reflected the fine structure of the synaptic barrage from GPe, as well as its onset and offset. NEW & NOTEWORTHY The pallido-nigral pathway connects the striatum to spontaneously active basal ganglia output neurons in the substantia nigra. Each substantia nigra neuron receives powerful inhibitory synaptic connections from a small group of globus pallidus cells and may fire during pauses in pallidal activity. Despite lacking any hyperpolarization-activated rebound currents, they fire quickly to even brief pauses in the pallido-nigral inhibition. The mechanism of their rapid disinhibitory response is explained by features of their phase-resetting curves.

Resumen

Independent mobility refers to children’s liberty to play freely in the neighbourhood without been supervised by adults. However, mobility restriction has affected child-friendliness in military barrack community in developing countries including Nigeria. The study aimed to explore principles of independent mobility in creating child-friendly barrack. Thirty journal articles related to children’s environment studies, military geographies and barrack housing were reviewed and analyzed. Children’s level of independent mobility impacts their physical, social, cognitive, and emotional developments. Consequently, walking or cycling-friendly environment as active travel mode was found to have positively contributed to improved well-being and quality of life of children in military barracks.

Resumen

Electricity generation from the sea has many advantages in comparison with other renewable energy resources. Power can be generated from new or existing barrages. Based on previous location research, a suitable system to produce tidal range energy from a potential site was developed in this paper. The main objective of this research is to calculate the energy output of the Kuching Barrage of Sarawak State of Malaysia. The daily flushing process of Kuching Barrage is conducted during the low tide period and therefore to put up the ebb generation process is appropriate. The calculated period of power generation is determined to about 6 hours. The annual energy output is calculated based on a theoretical method, with the average daily potential energy calculated to be 5.8MW and approximately 10.23GWh/year could be harnessed. This research can be beneficial for energy generation with the use of a double basin scheme for the construction of new barrages in East Malaysia.

Resumen

The Water Apportionment Accord (WAA) of Pakistan was instituted in 1991 to allocate Indus River water among Pakistan’s provinces. This paper assesses the performance of the WAA in terms of the accord’s ability to meet the barrages’ and environmental demands in the Lower Indus Basin. Use of metrics as assessment tools in water security and climate adaptation is an important field, with the potential to inform sustainable management policy. Reliability, resiliency, and vulnerability are used as indicators to define the system’s performance against supply. The results indicate from the pre-Accord period to the post-Accord period, the reliability of Guddu Barrage (the upstream-most barrage in the study) is not changed. However, at Sukkur and Kotri, the most downstream barrage in the study, reliability has significantly decreased. The Results reveal the high vulnerability of the Indus delta in Rabi season when the flows decline and the majority of the water at the Kotri Barrage is diverted.

Resumen

Large barrages have been constructed on the main rivers in South Korea to store water and mitigate fluvial flooding damage. However, the increase in water levels behind the barrages can potentially lead to a rise in groundwater levels in the riversides. The purpose of this study was to describe the effect of a barrage on groundwater levels and to test the applicability of a numerical model to groundwater inundation in this context. The Shincheon–Baekcheon catchment is characterised mainly by agricultural land use and includes significant greenhouse cultivation. Its two zones, which are lower A and upper B basins, mainly yield fine- and coarse-grained deposits, respectively. Trend and distribution analyses of manual and automatic measurements of groundwater levels indicated that: (1) the groundwater levels generally increased as the river water levels rose after the river was dammed; (2) the significant correlation between groundwater and river water levels could lead to reductions in the groundwater levels if the barrage gates were opened as a control measure; and (3) the lowering of high groundwater levels during dry seasons is important for preventing soil wetting in the riversides.

Resumen

For tidal power barrages, a breast-shot water wheel, with a hydraulic transmission, has significant advantages over a conventional Kaplan turbine. It is better suited to combined operations with pumping that maintain the tidal range upstream of the barrage (important in reducing the environmental impact), and is much less harmful to fish. It also does not require tapered entry and exit ducts, making the barrage much smaller and lighter, so that it can conveniently be built in steel. For the case of the Severn Estuary, UK, it is shown that a barrage at Porlock would generate an annual average power of 4 GW (i.e. 35 TWh yr −1 ), maintain the existing tidal ranges upstream of it and reduce the tidal ranges downstream of it by only about 10%. The weight of steel required, in relation to the annual average power generated, compares very favourably with a recent offshore wind farm.

Resumen

The purpose of the present research was to investigate the structural relationships of role differentiation, cohesion, team member satisfaction, and perceived group performance and to examine the moderating effects of barrack’s structure and squad leader’s initiating structure in these relationships. A total of 924 ROK Army soldiers participated in this research and data were collected through survey. Results of the structural equation modeling analysis showed that role differentiation was positively related to cohesion, team member satisfaction, and perceived group performance, respectively. Also, cohesion mediated the relationships between role differentiation and team member satisfaction as well as between role differentiation and perceived group performance. The moderating effect of barrack’s structure in the relationship between role differentiation and team member satisfaction was significant, suggesting that team member satisfaction was higher in the hierarchical barrack than in the horizontal barrack when soldiers perceived that the role differentiation was high. The moderating effect of squad leader’s initiating structure in the relationship between role differentiation and perceived group performance was also significant, suggesting that the relationship between role differentiation and perceived group performance was stronger when squad leader’s initiating structure was high than low. Lastly, the results, implications, and limitations of this research were discussed.

Resumen

The subject of the article is an analysis of the stabilisation method of the western gable walls of a barrack with the inventory number B-123, situated at the section BI of the former German Nazi concentration and extermination camp Auschwitz II-Birkenau. The barracks of the former Birkenau have a documentary and historical value and are subject to protective conservation. A barrack with inv. no. B-123 had been erected in the last months of 1941 as a residential barrack, then it was used as a hospital facility. The barrack walls are characterised by low stiffness, because with the building’s plan of 36.17 m  11.39 m, the walls are only 0.12 m thick. Gable walls have been greatly deformed, as a result they have detached from longitudinal walls and their deflection is up to 120 mm. The construction of the walls is at risk, because a bad-quality wall is loaded with horizontal and vertical forces transmitted from the roof, on the eccentricity reaching 120 mm. Deformations are progressing as a consequence of such forces and the walls must be stabilised. In case of the western wall, it was decided to stop its further deformation and to increase the local carrying capacity by stabilising with steel elements connected with ties anchored in the ground. Given the historical value of the plasters with paint coats layers covering the wall, it was decided not to remove the wall deformation mechanically. For the eastern wall, which is not covered with plaster and was partly reconstructed after the war, the removal of its deflection by rectification was designed.

Resumen

Malgré la présence de nombreux barrages au Québec, peu d'études ont été consacrées à l'analyse des impacts de ces ouvrages sur les régimes hydrologiques des cours d'eau. La présente note a pour but d'analyser les impacts d'un barrage sur le régime hydrologique de la rivière Matawin en comparant le régime hydrologique de la rivière en amont (1390 km2) et en aval (4070 km2) du barrage pendant une période de 60 ans (1930-1990) et sur trois échelles temporelles distinctes. A l'échelle interannuelle, l'influence du barrage se manifeste par une persistance plus marquée des effets des épisodes humides ou secs ainsi qu'une hausse ou une baisse des débits moyens annuels respectivement durant ces périodes. Mais cette succession et cette persistance n'ont pas affecté significativement la stationnarité de la série hydrologique. Aux échelles mensuelles et saisonnière, l'influence du barrage se manifeste par une inversion du régime hydrologique caractérisée par une hausse des débits hivernaux et une baisse des débits printaniers. Cette influence se traduit aussi par une baisse significative du débit maximum mensuel mais une hausse du débit minimum mensuel. Il en résulte une diminution du coefficient d'immodération. A l'échelle journalière, le barrage modifie la période d'occurrence des débits extrêmes minimums et maximums. Il provoque la diminution significative des débits extrêmes minimums et maximums. Mais l'écrêtement des crues est modéré pour les débits de récurrence=10 ans. L'impact le plus significatif du barrage de Matawin est sans nul doute l'inversion du régime hydrologique dont les conséquences morphologiques et biologiques ne sont pas encore documentées dans la littérature scientifique canadienne. Cette inversion résulte du faible écoulement hivernal et d'une forte production de l'énergie électrique pendant la saison froide.

Resumen

G. I. Taylor's approximate analytical solution for the tidal flow in the Severn estuary is extended to find the optimum location for a tidal power barrage, from the power point of view. It appears to be at the lowest point in the estuary, between Ilfracombe and Gower – contrary to earlier computations. The analytical solution shows that barrages radiate tidal waves out to sea, which highlights the important role of the far-field boundary condition in absorbing them. This appears to have been neglected in numerical models, which may explain the difference from the earlier results.

Resumen

In the Dutch part of the Rhine many hydraulic works (sluices, barrages, etc.) are situated which are considered to be barriers for upstream fish migration. Because of intensive shipping these works are always combined with big shipping locks. Until recently no data were available concerning fish migration via these locks. This was studied in the river Lek at the Hagestein barrage. Due to the short length of the study period and few recaptured salmonids (salmon, sea trout, rainbow trout) no conclusive evidence about the effects of the shipping lock on salmonid migration was obtained. However, the results do suggest that the Hagestein barrage complex forms a serious barrier for upstream migration of salmonids. Several other fish species on the other hand were observed to migrate through the lock. Therefore, depending on target species and management goals, the presence of shipping locks should be taken into account when considering improving fish migration possibilities.

Resumen

Résumé L’Algérie, caractérisée par un climat semi-aride, est menacée par l’érosion des terres agricoles qui provoque l’augmentation du transport solide et l’envasement croissant des barrages. Cet article décrit une nouvelle méthode d’estimation des flux de matières en suspension (MES) au niveau d’un barrage algérien (barrage de Beni Amrane) basée sur la logique floue. Cette dernière utilise des termes flous tels que « faible », « moyen » et « élevé », pour décomposer le processus débit-MES en plusieurs sous-ensembles flous et d’en déduire les quantités de matières solides en fonction du débit observé de la rivière. Les performances de cette méthode ont été évaluées en période de calage, mais aussi en période de validation, pour mieux juger de la capacité prédictive du modèle à ces deux échelles. En comparant la logique floue avec un modèle empirique régressif utilisant une relation de puissance, nous avons démontré la robustesse du modèle flou en tant qu’outil de quantification du transport solide.

Resumen

This study was conducted to examine the discharge capacity of the reach of the Tigris River between Kut and Amarah Barrages of 250km in length. The examination includes simulation the current capacity of the reach by using HEC-RAS model. 247cross sections surveyed in 2012 were used in the simulation. The model was calibrated using observed discharges of 533, 800, 1025 and 3000m3/s discharged at Kut Barrage during 2013, 1995, 1995 and 1988, respectively, and its related water level at three gauge stations located along the reach. The result of calibration process indicated that the lowest Root Mean Square Error of 0.095 can be obtained when using Manning’s n coefficient of 0.026, 0.03 for the Kut- Ali Al Garbi and Ali Al Garbi- Amarah reaches respectively, and 0.03 for the flood plain of the whole reach under study. The reach under study has two lateral inflow streams, UmAljury, which joins Tigris River at station 51km, and Aljabab, which joins Tigris River at station 57km. The discharge of Aljabab varies between 0 and 400m3/s and the discharge of UmAljury varies between 0 and 50m3/s. The results showed that the current capacity of the main channel of the reach of the Tigris River between Kut and Amarah Barrages is 400m3/s. The water levels kept less 1m than both levees in case of discharging 1800m3/s from Kut Barrage, with no lateral inflows, and 1700m3/s with lateral inflow. The reach of Tigris River fails to accommodate the flood discharge of 3300m3/s which is the discharge of the flood of 1988 measured at Kut Barage. It can be concluded that the reach had large amount of sediment for the period from 1988 to 2012 and the reach capacity reduced to about half its capacity of 1988 during this period. The results of removing 12 islands and 2 sidebars by reshaping the current condition into trapezoidal cross-section will decrease the surface water levels by 20cm and flow of 1900m3/s can be discharged safely at Kut Barrage without any lateral inflow and 1800m3/s with lateral inflow from the tributaries. While, expand 58 narrow cross-sections that choking the flow, the water levels along the reach are lowered by an average of 20cm in addition to that 20cm when modifying the cross-sections at the islands and sidebars. In this case, flow of 2100m3/s can safely be discharged from Kut Barrage without any lateral inflow and 1900m3/s with lateral inflow. The result when modifying additional 111 cross-sections showed that the reach can safely accommodate a flood wave of 3300m3/s from Kut Barrage without any lateral inflow and 3000m3/s with lateral inflow.

Resumen

L’objectif de notre travail est d’utiliser les sédiments de dragage du barrage de Gargar (Algérie) dans le domaine de l’industrie des matériaux de construction. Cette industrie possède un caractère stratégique dans les pays en développement : outre son poids économique considérable, elle favorise le dynamisme de son principal client, l’industrie du bâtiment et des travaux publics. Celle-ci contribue pour une large part à l’investissement national et au développement de l’industrie des matériaux de construction locaux. La disponibilité locale de matériaux de construction est un enjeu vital du développement pour les raisons suivantes : elle correspond à une demande essentielle des populations les plus démunies pour obtenir un logement à un coût acceptable, elle structure le développement des autres branches et elle constitue l’une des principales articulation des secteurs modernes et informels de production. Les résultats de cette étude montrent que les caractéristiques physiques et minéralogiques des sédiments d’envasement du barrage de Gargar (wilaya de Relizane) permettent leur utilisation dans l’industrie des briques, en comparaison avec celles produites actuellement, et ceci pour réduire les coûts de dévasement des barrages et protéger l’environnement des quantités importantes que présentent ces particules qui ne sont pas exploitées.

Resumen

The key goal of the Water Framework Directive is to achieve a good ecological status in water bodies. The ecological status is mainly determined by the biological elements, which are a very good indicator of the changes taking place in water environments. Thus, this article focuses on the analysis of different methods of assessment of the ecological status of water bodies based on macrophytes used in selected countries in the European Union (the Macrophyte Index for Rivers (MMOR)—Poland; the Mean Trophic Rank (MTR)—Ireland; the Trophic Index of Macrophytes (TIM)—Bavaria, Germany; the Bulgarian Reference Index of Macrophytes (RI-BG)—Bulgaria). Three research sections have been selected for research on the river Ślęza: The reference section, the section above the barrage and the section below the barrage. The analysis carried out revealed considerable similarity between the results obtained by all these methods—the differences were at most by one class of ecological status (and the analysis of sums of Wilcoxon’s ranks revealed that there were no differences between the results obtained using different methods, i.e., p = 0.860). With respect to surface waters, investigation of biological elements is important because it allows one to retrace the past and foresee the future based on the past and present trends in the changes occurring in the species diversity and structure of not only macrophytes, but also other groups of organisms. Further action is required that would determine the scope of influence of barrages with hydroelectric buildings on the environment (in the case of the investigated barrage this influence is negative).

Resumen

L’érosion des sols et le transport solide sont des causes de perte de capacité de stockage des barrages. Il est important d’identifier et de cartographier les sous-bassins contribuant le plus à l’envasement. Le bassin versant de l’oued Bouregreg a été choisi pour exemple, car le barrage Sidi Mohammed ben Abdellah (SMBA) situé à l’aval s’envase. Les modèles utilisés, RUSLE (équation universelle révisée des pertes de sol) et MUSLE (équation universelle des pertes de sol modifiée par Williams), sont empiriques et bien connus. Ils permettent la réalisation d’une cartographie thématique facilitée par l’utilisation de systèmes d’information géographique. À l’issue de cette analyse, les sous-bassins générant une forte érosion seront clairement mis en évidence pour que des mesures correctives y soient mises en œuvre.

Resumen

Twenty-nine vegetative compatibility groups (vcgs) were identified among 297 isolates of the fungus causing soybean stem canker in the southeastern United States (southern Diaporthe phaseolorum). Of the isolates characterized, 79% were from one of the vcgs described (group 1). Barrage zones formed between isolates from different vcgs when grown on potato dextrose agar, and also formed, but not always distinctly, on cornmeal agar, Czapek-Dox agar, lima bean agar, and malt agar; barrages did not form on Sach's agar or water agar. Two types of evidence suggested that southern D. phaseolorum is homothallic. Perithecia and viable ascospores were produced by single ascospore isolates, and ascospores produced by mass isolates were always of the same compatibility group as the parental mass isolate.

Resumen

AbstractThe idea of ‘developing’ Sind has been a lynchpin of government action and rhetoric in the province during the twentieth century. The central symbols of this ‘development’ were three barrage dams, completed between 1932 and 1962. Because of the barrages’ huge economic and ideological significance, the ceremonies connected with the construction and opening of these barrages provide a unique opportunity to examine the public presentation of state authority by the colonial and postcolonial governments. This paper investigates the way that ideas of ‘development’ and ‘modernity’ appeared in discourses connected with these ceremonies, in order to demonstrate that the idea of imposing ‘progress’ on a province considered ‘backward’ by the state administrators survived longer than the British regime which had introduced it. The paper begins with the historical links between water-provision and governance in Sind, before examining the way that immediate political concerns of the sitting governments were addressed in connection with the projects, demonstrating the ways in which very similar projects were cast as symbols of different political priorities. The last part of the paper draws out deeper similarities between the logic of these political expressions, in order to demonstrate the powerful continuity in ideologies of ‘progress’ throughout mid-twentieth century Sind.

Resumen

The total population of Indus Dolphins, numbering perhaps 500 individuals, is subdivided by barrages into five or six subpopulations. At least two of these are so small (fewer than 20 animals) that they have little chance of survival past the next few decades. If dispersal occurs at all, because of barrages it will apparently only be downstream, causing a net loss to upstream subpopulations. The subpopulation in Sindh Dolphin Reserve, between Sukkur and Guddu barrages, is relatively large and apparently well-protected. However, the small size of the Reserve, its geographical position near the downstream end of the species range, and the political and economic instability of the area, taken together, mean that this subpopulation is at considerable risk. The need for additional reserves upstream of Guddu Barrage, to improve the prospects of the species' survival, is clear.The subpopulation downstream of Taunsa and Panjnad barrages is unquestionably the largest in Punjab, and its protection should be a high priority of the Punjab Government. Apart from the obvious need to prevent both direct capturing and accidental killing, the Dolphins' aquatic habitat must be carefully safeguarded. Any additional withdrawal of water from the Indus and its tributaries, whether for agriculture or industry, would be inimical to Dolphin conservation. Moreover, any project involving changes to the river system's hydrography and water-quality, even if expected to have no net effect on discharge levels in the main channels, should be evaluated critically for the potential impact on Dolphins.It is important to emphasize that responsibility for the fate of Indus Dolphins and the many other organisms affected by major water-development schemes, is shared by a number of countries in addition to Pakistan. We hope that foreign governments, in their efforts to support Pakistan's economic development and relieve poverty in the subcontinent by assisting in the planning and financing of water megaprojects, do not in the process contribute to the impoverishment of the client country's, and in turn the world's, ecological heritage.

Resumen

La présente étude s'inscrit dans le cadre d'un programme de recherche sur la gestion des lacs et barrages collinaires en zone méditerranéenne HYDROMED. Elle a pour objectif le suivi hydrologique et la sédimentation du barrage collinaire Saboun, situé dans la zone de Tanger au Nord-Ouest du Maroc. Un dispositif hydro-pluviométrique automatique a été installé à ce sujet depuis novembre1997. Il a permis le suivi du bilan en eau de la retenue et l'analyse de son fonctionnement hydrologique. Parallèlement, une étude de la bathymétrie par sondage ponctuel a montré que le taux de sédimentation est de l'ordre de 2% par an. Cette perte en eau de la capacité totale de la retenue est une conséquence directe d'une forte dégradation des sols du bassin versant estimée à 115 T/ha/an.

Resumen

Neste trabalho é resumido um estudo experimental sobre o comportamento de emendas por traspasse de barras comprimidas em pilares de concreto armado, com o objetivo de investigar a influência da distância entre as barras emendadas sobre o comportamento da emenda. O estudo englobou os ensaios à compressão centrada de dois pilares: um com emenda com barras em contato e outro com emenda com barras separadas a uma distância igual a duas vezes o diâmetro das barras da armadura longitudinal, φl. Nos pilares ensaiados, constatou-se que a tensão média de aderência na emenda praticamente não depende da distância entre as barras. Para ambos os pilares, próximo à carga última, a tensão normal nas pontas das barras apresentou valores muito superiores à resistência uniaxial à compressão do concreto.

Resumen

Historical barrack complexes constitute a separate genre in architectural typology and a crucial component of cultural landscape in garrison towns. Their construction impacted spatial development of historic cities. Military compounds were usually formed in a raster pattern, which spawned the grid plan further to adjacent streets forming a connection with the existing urban area, thus stimulating growth and modernization of cities. Originally positioned on the outskirts, today they become liaisons between historic downtowns and contemporary suburbs. They are excellently suited for that role, because by default they are utilitarian. Still they are endangered and neglected. For singleminded investors their material substance is worthless compared to the land they stand upon. The Wrzeszcz Barracks give proof that there exists a way to innovatively reintroduce this genre into city scope. Following in the footsteps of European exponents in Turin or Freiburg, the ‘Garnizon Neighborhood’ is one of the most successful mix-use regeneration efforts of post-military complexes in Poland. The paper constitutes a case study of regeneration indicating its strong and weak points in relation to similar undertakings.

Resumen

Este trabalho baseia-se na substituição de barras de aço convencional por barras de GFRP (Glass Fiber Reinforced Polymer) em estruturas de concreto armado. Foram dimensionadas, à flexão, vigas de concreto armadas com barras de aço, as quais seguiram a recomendação da norma ACI 318 (ACI, 2019), e vigas de concreto armadas com barras de GFRP com o uso da recomendação ACI 440.1R (ACI, 2015), a fim de se estudar, comparativamente, a capacidade de carga e o modo de ruptura destes elementos. Cotações de preços foram realizadas para a comparação dos custos de execução das vigas. Foi possível concluir que, com taxas de armadura equivalentes, verifica-se que uso de barras de GFRP leva a obtenção de capacidades resistentes superiores entre 177 e 113% para as mesmas seções dimensionadas com aço convencional. Quando se considera o mesmo diâmetro para as barras de GFRP e aço, percebe-se que as que vigas armadas com aço CA-50 apresentam capacidade resistente 20% superior à das vigas armadas com barras de GFRP. Com relação ao modo de ruptura, o das vigas armadas com barras de aço convencionais é baseado no escoamento da armadura, enquanto aquelas armadas com barras de GFRP é baseada na ruptura das barras à tração ou no esmagamento do concreto comprimido. Por fim, os custos de execução das vigas armadas com barras de GFRP, em curto prazo, são maiores do que os custos de execução de vigas armadas com barras de aço. Entretanto, é necessário avaliar os possíveis custos com manutenção das estruturas, dado que as vigas armadas com barras de GFRP são mais resistentes às condições de agressividade do ambiente e apresentam menores custos de manutenção quando se leva em conta a vida útil de projeto das estruturas de concreto armado.

Resumen

AbstractThis paper describes the Quaternary geology of the area around Gasr Banat which lies near the confluence of the Wadis N'f'd and N'fed in the pre-desert of Tripolitania. The site is of interest because of its aridity, the notable archaeological remains that occur in the region and the opportunity it offered to map the surficial deposits of an area otherwise largely unknown. The survey revealed that two Pleistocene cobble and gravel units laid down by ‘torrential’ rivers could be distinguished: the older of which had been cemented by calcrete. Polyphase slope deposits occur. Thin section studies of the calcrete suggests it is possible to recognise two arid and two humid episodes from its micromorphology.The Holocene period is represented by water-lain and aeolian deposits on the wadi floodplain, and climbing and barchan dunes on the adjacent hills. The period immediately prior to the construction of major cross wadi barrages may have been characterised by larger or more frequent floods than occurred immediately prior to the 1984 survey; the palaeoclimatic significance of this observation is unclear. One major barrage in the area is shown to have been built on substantial earth foundations. The assumed Romano-Libyan date of these barrages still remains to be proven, but, conversely, it is now demonstrated that they were not constructed or reconstructed in the 1950s.

Resumen

La semilla de quinoa (Chenopodium quinoa Willd) se caracteriza por presentar una composición balanceada; es rica en proteínas, fibra, vitaminas, minerales y antioxidantes, por lo que puede ser incorporada en la formulación de barras de cereal a fin de incrementar el valor nutricional de la alimentación diaria. El objetivo de este trabajo fue estudiar el efecto de la incorporación de semillas de quinoa en la calidad tecnológica, nutricional y sensorial de barras de cereal. Se elaboraron y analizaron tres muestras de barras de cereal, con diferentes porcentajes de sustitución de arroz crocante por semillas de quinoa y un control (sin quinoa). Se observó un incremento de peso de las barras de cereal, a medida que se aumentó el nivel de sustitución y una disminución en el largo de éstas. La dureza de las barras fue afectada, obteniéndose barras más blandas cuando tenían quinoa en la formulación. La incorporación de quinoa generó un aumento en el contenido de minerales, proteínas y fibra alimentaria del producto final. Además, las barras de cereal con quinoa presentaron una digestibilidad más lenta del almidón. A los consumidores les resultó agradable el sabor de las barras con quinoa y también tuvieron una buena aceptabilidad global.

Este trabalho trata sobre o comportamento estrutural de vigas de concreto armadas com barras de compósito de resina e fibras de vidro (GFRP). A partir de um programa experimental, 6 (seis) vigas de concreto armado de 150 mm x 150 mm x 1500 mm de dimensões foram ensaiadas à flexão em quatro pontos. Os parâmetros variados nestas vigas foram o material das barras (aço ou GFRP) e a taxa de armadura longitudinal (0,88% e 2,02%). A resistência média do concreto à compressão foi 25 MPa. Foram monitorados até a ruptura das vigas os valores de flecha, deformação específica das armaduras (transversal e longitudinal) e do concreto, e abertura de fissura no vão de flexão pura. Os resultados mostraram que as vigas com barras de GFRP apresentaram resistência próxima à das vigas com barras de aço. Por causa da menor rigidez à flexão, os valores de flecha e de abertura de fissura das vigas com barras de GFRP foram maiores que os das vigas com barras de aço.

Resumen

The “Ecological Master Plan for the Rhine (Salmon 2000)” was elaborated within the framework of the “Rhine” Action Programme (RAP). It focuses on two points.Restoration of the main stream as the backbone of the ecosystem Migratory fish can only return to the Rhine when certain conditions are given. Improvement measures must be realized. For the support and realization of the project “Salmon 2000” two applications for subsidies were approved by the European Community. The first project concerns various habitat improvements, re-establishing, re-stocking and success control measures in several Rhine tributaries. The second project concerns the methods of improvements at barrages which are currently considerable obstacles to migration. At the barrages of Iffezheim and Gambsheim/Upper Rhine, new fish ladders must be built. The Master Plan will only prove successful if the re-establishing and restocking of habitats is being carried out simultaneously with measures aiming at reestablishing the surmountability of barrage weirs.Preservation, protection and improvement of ecologically important reaches. The plan demands an extension of the alluvial areas. Complete ecological interaction between these areas and the river must be allowed. A group is working on a specific ecological network with the most important alluvial areas along the Rhine. These areas shall serve as “stepping stones” for the whole Rhine ecosystem. This plan may be considered as an exemplary conception of international waterways protection. Its significance includes amongst other things the applicability to other similar river systems.

Resumen

Nigerian military army barracks are a rich domain in which soldiers and officers display different strands of their identity. A typical army barracks in Nigeria often accommodates many ethnic groups owing to the federal policy governing the recruitment of both soldiers and officers. Thus, it is common in the barracks for military men to be aware of their ethnic, linguistic, religious, and regional affiliations and to relate to one another based on these various affiliations. It is against this backdrop that the present study seeks to investigate how soldiers and officers make use of linguistic resources available to them to convey religious, occupational, ethnic, and linguistic identity in the barracks. Data for the study were collected from 46 military men, soldiers and officers, in four military barracks. The locationss are Akure, Enugu, Saki, and Zaria Barracks. The instruments used in gathering the data were questionnaire, face-to-face interviews, and participant observation. The study revealed that both soldiers and officers represent their occupational identity through the specific use of certain lexical items and slang, while their ethnic identity is signified through the use of ethnic and other local languages. Their personal names were also observed to be symptomatic of their religious identity.

Resumen

Durante terremotos es de esperar que las barras de acero de refuerzos en estructuras de concreto, experimenten deformaciones cíclicas de tensión y compresión. Debido a separaciones inadecuadas del refuerzo transversal, el estado de deformaciónes inélasticas de típico cíclico reversible en barras de acero de refuerzo puede llevar al pandeo de estas barras. A un cuando diversos reglamentos de construcción estipulan separaciones máximas de refuerzo transversal, dichas separaciones se basan generalmente en resultados de pocos estudios experimentales.En esta invstigación se efectuó un estudio experimental con el fin de evaluar el comportamiento de barras de acero de refuerzo cortas y esbeltas, sometidas a cargas comprensión monotónicas, así como ciclícas revesibles. Para la obtención de curvas esfuerzo-deformación de barras cortas de acero de refuerzo sometidas a ambos tipos de cargas se utilizaron modelos analíticos propuestos en la literatura. los cuales permiten definir este tipo de curvas a partir de la tensión. La correlación de resultados obtenidos con estos modelos y los experimentales fue aceptable. Se comparan los resultados obtenidos en los ensayos experimentales ante cargas cíclicas reversibles de barras esbeltas, con los de un modelo analítico propuesto en la literatura, empleado además un críterio de definición de pandeo desarrollado en este estudio. Con base a los resultados obtenidos se dan recomendaciones para evaluar el fenomeno del pandeo de barras de refuerzo sometidas tanto a cargas monotónicas como cíclicas reversibles.

Resumen

Given difficulty in having children assess their own behaviour, there are few self reports on child impulsivity. With the exception of Eysenck's 16 questionnaire, there are no self-report measures of impulsivity in children with good psychometric properties. The present study tested the possibility of using the adolescent version of the Barrati Impulsiveness Scale-11 with children. For this purpose the questionnaire was translated and backtranslated and administered to school children (182 boys and 195 girls) ages 8 to 12 years ( M = 10.4, SD = 0.9). The data were analysed by exploratory factor analysis, to evaluate the factorial structure of the questionnaire, the fit of the proposed solution, and internal consistency reliabilities. Results seem to indicate that this questionnaire may be useful in assessing impulsivity in children. The three-factor structure showed slight differences with the initial questionnaire proposed by Barratt and had good or sufficient internal consistency (depending upon the scale) across the 8- to 12-yr.-old age range.

Resumen

Taking military barracks wastewater treatment as an example, this paper presents a new concept design of a modified DEWATS system with both the horizontal subsurface constructed wetland and aquatic plants pond. Results show that this process in treating the military barracks area wastewater have many advantages such as low operation cost, simple operation and maintenance, and the effluent could meet the urban wastewater treatment plant pollutant discharge standard "(GB18919-2002) for first level Class A. It is suitable for the military barracks which have difficulty to be connected to centralized sewerage treatment system. At the same time, it can effectively improve the internal and surrounding water environment around the military barracks. This is a flexible wastewater treatment technology and can be replicated and applied for decentralized wastewater treatment.

Introducción: El tratamiento de las escoliosis de inicio temprano guiado con barras magnéticas permite realizar distracciones no invasivas y ambulatorias. El objetivo de este estudio fue evaluar nuestra primera serie de casos con escoliosis de inicio temprano tratados con el sistema de barras magnéticas. Materiales y Métodos: Se realizó una revisión de casos tratados con el sistema de barras magnéticas entre 2014 y 2018. Se formaron dos grupos: grupo I (procedimientos primarios con barras magnéticas) y grupoII (conversiones de sistema tradicional a barras magnéticas). Resultados: Se evaluó a 19 pacientes. La edad promedio en el momento de la cirugía era de 7 años y 4 meses, con un seguimiento promedio de 2 años y 7 meses. El grupo I tenía 12 pacientes y el grupo II, 7 pacientes. Los valores angulares promedio preoperatorio y posoperatorio inmediato de la escoliosis fueron 62° y 42°, respectivamente; los de cifosis, 49° y 34°, respectivamente. La distancia T1-T12 fue de 160 a 176 mm. La distancia T1-S1 fue de 285 a 317 mm. Hubo una complicación: protrusión del implante e infección, y fue necesario retirar el material (grupo II). Conclusiones: Los resultados preliminares sugieren que es un método seguro y eficaz. Si bien los resultados a corto y mediano plazo son alentadores, persisten algunos desafíos importantes e incógnitas en relación con el comportamiento mecánico del implante en un seguimiento prolongado. Palabras clave: Escoliosis de inicio temprano; barras de crecimiento; barras magnéticas.Nivel de Evidencia: IV
