The currently popular distributed, n-tiered, object-oriented application architecture provokes many design debates. Designs of such applications are often divided into logical 'tiers'-usually user interface, business logic and domain object, or data, tiers, each with their own design issues. In particular, the latter contains data that needs to be stored and retrieved from permanent storage. Decisions need to be made as to the most appropriate way of doing this-the choices are usually whether to use an object database, to communicate directly with a relational database, or to use objectrelational mapping (ORM) tools to allow objects to be translated to and from relational form. Most often, depending on the perceived profile of the application, architects make these decisions using rules of thumb derived from particular experience or the design patterns literature. Examples include: object-oriented databases ease programming, relational databases ease report generation and data mining; object-oriented databases are good for navigation around an object model, relational databases are good for sequential processing and complex queries; if you are writing an application from scratch, use an object database, if you need to integrate to various sources of legacy data, use an ORM tool. Although helpful, these rules are often highly context-dependent and are often misapplied. Research into the nature and magnitude of 'design forces' in this area has resulted in a series of benchmarks, intended to allow architects to more clearly understand the implications of design decisions concerning object persistence. In this paper, the performance of selected open source object persistence tools is investigated, to attempt to clarify the myths surrounding the performance of the different options. In particular, we compare Hibernate, representative of the ORM stable, and db4o, representative of object-oriented databases. The OO7 benchmark is used to compare the speed of execution of a suite of typical persistence-related operations in both candidates. We then propose some preliminary explanations of the sometimes surprising results.

In this paper I have present Web design frameworks as a conceptual methodology to exhaust the possibilities reuse in Web applications. Firstly talk over the necessity for construction abstract and reusable directional design structures, demonstrating with different kinds of Web Information Systems. Hibernate Framework technology as a unique and well-organized resources to access massive databases and also emphases on how to implement persistent features in object-oriented system finished it. It provides an indication of design patterns and frameworks and discovers the association between design patterns and frameworks.Java accepts N-tier framework of MVC Model in J2EE platform and uses EJB, Struts Web Framework and Hibernate technology.

Os processos de delegação de tarefas por parte do chefe da Secretaria Administrativa do 11o Batalhão de Polícia Militar da cidade de São Miguel do Oeste eram até então realizados utilizando a delegação direta verbal ou meramente informativa via e-mail, ocasionando uma gestão menos eficiente dos trabalhos administrativos realizados naquela secretaria, ocorrendo por vezes ruídos na dinâmica de comunicação da equipe. Foi proposta a atenuação deste transtorno com a centralização das tarefas em um aplicativo web, o qual o presente estudo tem por objetivo desenvolver. A aplicação fará uso de tecnologias relacionadas à linguagem de programação Java e centralizando a criação, delegação, edição e encerramento de tarefas por parte dos profissionais da referida secretaria.

Natural nests of the European ground squirrel (Spermophilus citellus) are constructed almost exclusively of fresh fescue (Festuca pseudovina: Poaceae). We performed laboratory experiments to understand the functional significance of preference of wild squirrels for nest material. We examined the factors contributing to nest quality by monitoring the construction and analyzing the composition of squirrel nests. As in the wild, squirrels showed strong preference for fescue during the laboratory tests and preferred fresh material to dry material. Because preference for fresh material was not expected, because high water content reduces insulation, we manipulated the moisture content of nests made from either fresh or dry fescue to determine how nest quality and moisture level contribute to insulation. We found that the insulation property of fresh grass nests was superior to nests constructed from dry grass only. Intracellular water in the nest material did not affect thermal conductance and insulation significantly. We concluded that fresh fescue provided a more flexible material that allows squirrels to construct nests with better insulation under both field and laboratory conditions.

Hibernation (i.e., multiday torpor) is considered an adaptive strategy of mammals to face seasonal environmental challenges such as food, cold, and/or water shortage. It has been considered functionally different from daily torpor, a physiological strategy to cope with unpredictable environments. However, recent studies have shown large variability in patterns of hibernation and daily torpor (“heterothermic responses”), especially in species from tropical and subtropical regions. The arboreal marsupial “monito del monte” (Dromiciops gliroides) is the last living representative of the order Microbiotheria and is known to express both short torpor episodes and also multiday torpor depending on environmental conditions. However, only limited laboratory experiments have documented these patterns in D. gliroides. Here, we combined laboratory and field experiments to characterize the heterothermic responses in this marsupial at extreme temperatures. We used intraperitoneal data loggers and simultaneous measurement of ambient and body temperatures (TA and TB, respectively) for analyzing variations in the thermal differential, in active and torpid animals. We also explored how this differential was affected by environmental variables (TA, natural photoperiod changes, food availability, and body mass changes), using mixed-effects generalized linear models. Our results suggest that: (1) individuals express short bouts of torpor, independently of TA and even during the reproductive period; (2) seasonal torpor also occurs in D. gliroides, with a maximum bout duration of 5 days and a mean defended TB of 3.6 ± 0.9°C (one individual controlled TB at 0.09°C, at sub-freezing TA); (3) the best model explaining torpor occurrence (Akaike information criteria weight = 0.59) discarded all predictor variables except for photoperiod and a photoperiod by food interaction. Altogether, these results confirm that this marsupial expresses a dynamic form of torpor that progresses from short torpor to hibernation as daylength shortens. These data add to a growing body of evidence characterizing tropical and subtropical heterothermy as a form of opportunistic torpor, expressed as daily or seasonal torpor depending on environmental conditions.

Packet analysis is an important aspect of network security, which typically relies on a flexible packet filtering system to extrapolate important packet information from each processed packet. Packet analysis is a computationally intensive, highly parallelisable task, and as such, classification of large packet sets, such as those collected by a network telescope, can require significant processing time. We wish to

Akt (or protein kinase B) plays a central role in coordinating growth, survival and anti-apoptotic responses in cells and we hypothesized that changes in Akt activity and properties would aid the reprioritization of metabolic functions that occurs during mammalian hibernation. Akt was analyzed in skeletal muscle and liver of Richardson's ground squirrels, Spermophilus richardsonii, comparing the enzyme from euthermic and hibernating states. Akt activity, measured with a synthetic peptide substrate, decreased by 60-65% in both organs during hibernation. Western blotting showed that total Akt protein did not change in hibernation but active, phosphorylated Akt (Ser 473) was reduced by 40% in muscle compared with euthermic controls and was almost undetectable in liver. Kinetic analysis of muscle Akt showed that S 0.5 values for Akt peptide were 28% lower during hibernation, compared with the euthermic enzyme, whereas S 0.5 ATP increased by 330%. Assay at 10°C also elevated S 0.5 ATP of euthermic Akt by 350%. Changes in ATP affinity would limit Akt function in the hibernator since the muscle adenylate pool size is also strongly suppressed during cold torpor. Other parameters of euthermic and hibernator Akt were the same including activation energy calculated from Arrhenius plots and sensitivity to urea denaturation. DEAE Sephadex chromatography of muscle extracts revealed three peaks of Akt activity in euthermia but only two during hibernation suggesting isozymes are differentially dephosphorylated during torpor. Altered enzyme properties and suppression of Akt activity would contribute to the coordinated suppression of energy-expensive anabolic and growth processes that is needed to maintain viability during over weeks of winter torpor.

Creating Project Cost Estimation (PCE) and list of materials and staff requirements of a construction project should be done before do the project itself. This process needs careful and accurate analysis. Dinas Pekerjaan Umum (DPU) or Department of Public Works in Salatiga city still made PCE manually. It needs much of time and lack of accuracy. This article studies about how to design and implements efficient accurate PCE especially for building construction and rehabilitation by using prototyping method. The application in this article is implemented with Java language program, Hibernate, database server MySQL and multiuser feature that aims to improve the efficiency and precision of PCE making in DPU of Salatiga City in order to give better service to the public.

Para que um determinado serviço de TI atenda as reais necessidades de um negócio, sugere-se definir contratos internos com terceiros para garantir a sua qualidade, geralmente incluindo os acordos de nível de serviços (Service Level Agreements - SLAs). Para que se tenha um acompanhamento eficaz dos SLAs, busca-se criar indicadores, alimentados periodicamente, a partir dos canais de comunicação internos e externos aos provedores de serviços, uma vez que a informação positiva ou negativa sobre o serviço pode estar sendo gerada pelo service desk, e-mail, messenger, blogs, páginas da web relacionadas a reclamações, redes sociais, entre outros canais de comunicação. Este trabalho teve como objetivo realizar a coleta e pré-processamento de dados de um canal social para técnicas de mineração de dados na mineração de textos, visando coletar informação sobre possíveis violações de SLAs e baixa QoS.
