Abstract (sommario):

Mutations in rcsC that result in constitutive colanic acid capsule synthesis were obtained in Salmonella enterica serovar Typhimurium. Most rcsC alleles were dominant; however, recessive rcsC alleles were also found, in agreement with the postulated double role (positive and negative) of RcsC on the activation of the RcsB/C phosphorelay system. Salmonella rcsC mutants with constitutive activation of the Rcs system are severely attenuated for virulence in BALB/c mice and their degree of attenuation correlates with the level of Rcs activation. Partial relief of attenuation by a gmm mutation indi

Abstract (sommario):

Abstract Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western hemisphere, but its pathogenesis is still poorly understood. Constitutive tyrosine phosphorylation (p) of signal transducer and activator of transcription (STAT) 3 occurs in several solid tumors and hematologic malignancies. In CLL, however, STAT3 is constitutively phosphorylated on serine 727, not tyrosine 705, residues. Because the biologic significance of serine pSTAT3 in CLL is not known, we studied peripheral blood cells of 106 patients with CLL and found that, although tyrosine pSTAT3 was inducible, se

Abstract (sommario):

Cyclooxygenase-2 (COX-2) is an inducible enzyme that drives inflammation and is the therapeutic target for widely used nonsteroidal antiinflammatory drugs (NSAIDs). However, COX-2 is also constitutively expressed, in the absence of overt inflammation, with a specific tissue distribution that includes the kidney, gastrointestinal tract, brain, and thymus. Constitutive COX-2 expression is therapeutically important because NSAIDs cause cardiovascular and renal side effects in otherwise healthy individuals. These side effects are now of major concern globally. However, the pathways driving constit

Abstract (sommario):

Parasites represent a major threat to all organisms which has led to the evolution of an array of complex and effective defence mechanisms. Common to both vertebrates and invertebrates are innate immune mechanisms that can be either constitutively expressed or induced on exposure to infection. In nature, we find that a combination of both induced and constitutive responses are employed by vertebrates, invertebrates and, to an extent, plants when they are exposed to a parasite. Here we use a simple within-host model motivated by the insect immune system, consisting of both constitutive and indu

Abstract (sommario):

The nonlinear constitutive relations of clay are investigated with different initial stress conditions. Two series of triaxial compression tests are performed, respectively after consolidation and isotropic consolidation. On the basis of the framework of ~ model, a uniform nonlinear constitutive model is proposed by fitting of the test data. With the average slope of the unloading-reloading curve selected as the unloading modulus, the unloading function is constructed as the loading-unloading criterion. Moreover, a comparison of the experimental stress-strain curves with the predicted results

Abstract (sommario):

Fair play as a phenomenon of sporting life is present even if only in the form of small acts or gestures in most competitions; its absence is present in cases of foul play. The daily press comments its presence or absence every day in, and not only in the sports sections. Both the public and experts discuss acts from so called grey zone (forms of gamesmanship). Deciding unequivocally on the moral quality of a diverse range of actions, attitudes or statements requires clarity about the values underpinning fair play. Our aim is therefore to find the constitutive values of fair play by examining

Since the enactment of Law Number 19 of 1992 on Trademarks that had been amended last with the enactment of Law Number 20 of 2016 on Trademarks, it applies the Constitutive System (First to File) which is a change from the old system of the Declarative System (First to Use). Therefore, the legal protection is determined by a registration. However, there are still many lawsuit cases of trademark cancellation. Based on the Constitutive System, the right is granted to the first registrant. Some cases are based on a lawsuit from a party who feels as the owner of the trademark, but registered by an

Abstract (sommario):

Human populations are at risk of exposure to constitutive androstane receptor (CAR) activators present in a range of substances, including pharmaceuticals, plasticizers and crop protection agents. What exposure to CAR activators means for human health is uncertain. Activation of CAR in rodents is associated with liver hyperplasia, increased proliferation and eventual hepatocarcinoma; however the effect in human hepatic cells is unclear. There are two methods by which a compound can achieve activation of CAR; directly or indirectly via cellular signalling pathways. Phenobarbital is a prototypic

The governing equations of the system are obtained. By posing an inverse problem, the model is used to simulate the estimation of coupled substrates' material (constitutive) parameters. In the inverse problem, beam deformations are considered as measured parameters, and therefore an eventual hardware implementation would require measurements of these quantities. Different case studies are simulated to as

This is important: it offers a sense of how the natural register is open to thought and yet, simultaneously, a source of that which has the perpetual possibility of undermining conceptual distinctions and anticipations.

The main functions of the human musculoskeletal system are to sustain loads and provide mobility. Bones and joints themselves cannot produce movement; skeletal muscles provide the ability to move. Knowledge of muscle forces during given activities can provide insight into muscle mechanics, muscle physiology, musculoskeletal mechanics, neurophysiology, and motor control. However, clinical examinations or instrumented strength testing only provides information regarding muscle groups. Musculoskeletal models are typically needed to calculate individual muscle forces.

Parameter determination of advanced cyclic plasticity models which are developed for simulation of cyclic stress-strain and ratcheting responses is complex.

Moreover, manual parameter determination for an advanced plasticity model requires in-depth knowledge of the model and experience with its paramet

Abstract (sommario):

Recent concerns regarding global warming and energy security have accelerated research and developmental efforts to produce biofuels from agricultural and forestry residues, and energy crops. Anaerobic digestion is a promising process for producing biogas-biofuel from biomass feedstocks. However, there is a need for new reactor designs and operating considerations to process fibrous biomass feedstocks. In this research project, the multiphase flow behavior of biomass particles was investigated. The objective was accomplished through both simulation and experimentation. The simulations included

Abstract (sommario):

In 2015, Nepal adopted a federal system of governance abandoning the previous centralized, unitary, feudal and autocratic system to address systemic exclusion and discrimination. The Constitution of Nepal devolved state power amongst three spheres of government. Entrenched into five separate lists, these powers are both exclusive and concurrent. However, many of the powers that look exclusive at the onset are essentially concurrent due to the widespread duplication of subject areas within and across these lists. Against this backdrop, I argue that the pervasiveness of concurrency in Nepal’s di

Abstract (sommario):

The 1991 Colombian Constitution strengthened the checks and balances of the political system by enhancing the role of Congress and the Constitutional Court, while somewhat limiting the powers of the President (who nonetheless remains extremely powerful even by Latin American standards). As a consequence of the larger number of relevant players, and the removal of barriers that restricted political participation, the political system has gained in terms of representation. However, political transaction costs have increased, making cooperation harder to achieve. The authors show that this has be

Abstract (sommario):

There is much to learn from the recent New Zealand and Japan earthquakes. These earthquakes produced differing levels of liquefaction-induced ground movements that damaged buildings, bridges, and buried utilities. Along with the often spectacular observations of infrastructure damage, there were many cases where well-built facilities located in areas of liquefaction-induced ground failure were not damaged. Researchers are working on characterizing and learning from these observations of both poor and good performance. The “Liquefaction-Induced Ground Movements Effects” workshop provided an opp

Abstract (sommario):

Healthcare-associated infections are a major cause of morbidity and mortality, and constitute a significant burden on health systems. Hand hygiene is regarded as an effective preventive measure but the frequency of hand hygiene by healthcare workers is low.

Testo completo

Abstract (sommario):

The project investigated the molecular genetic and biochemical basis of pollination-induced senescence of Phalaenopsis flowers. This experimental system offered unique advantages in that senescence is strictly regulated by pollination, providing the basis to experimentally initiate and synchronize senescence in populations of flowers. The postpollination syndrome in the Phalaenopsis orchid system was dissected by investigating the temporal and spatial regulation of ACC synthase gene expression. In the stigma, pollen-borne auxin induces the expression of the auxin-regulated ACC synthase (PS-ACS

Abstract (sommario):

Having a right that is not respected is not the same as having no right at all. At least this should not be the case. Failure to receive something to which you are entitled should lead to formal redress or failing that, protest. The rights-based discourse has a wider importance. If and when it is or should be used is significant. In terms of access to social protection (including social and humanitarian assistance), the rights-based discourse means there is no difference between refugees and others who fail to receive the protection to which they are entitled, such as Internally Displaced Peop

Abstract (sommario):

The governance of Technical and Vocational Education and Training (TVET) in Nepal was heavily centralized in the past as the country was operating under a unitary government system. The 2015 Constitution has opened the avenue to operate the TVET sector in a federalized setting with the sharing of TVET functions along with power and authority by three tiers of government. However, the sharing of power and authority between the federal and subnational governments has not been easy as highlighted by the Constitution. This paper attempts to analyse the challenges that are hindering the smooth tran
