Abstract:

Roller linear guides are key components in machine tool. The accuracy and efficiency of a machine toll are determined by the stiffness and friction torque of roller guide. This study proposes an improved design method for roller guide. The influences of the rollers profile on stiffness, stress distribution of roller linear guide are analyzed using finite element simulation. In this work, the design of the roller, slider, and the overall structure is modified. Moreover, experimental investigations on noise and sliding friction of roller linear guide are compared to validate the proposed design

Abstract:

In traditional studies of linear motion roller guide, the static stiffness is a main indicator to evaluate the mechanical behavior. However, the local contact profile between the roller and raceway surface, although very important to the precision maintenance, cannot be reflected in the measured value of static stiffness. In this article, a new indicator, named the real contact total length (RCTL), is proposed based on the Greenwood–Williamson model and the Hertz contact theory. In particular, an electric contact model is presented where the RCTL of linear motion roller guide without preload i

Abstract Steel structures for a conveyance guiding system are subjected to prolonged, intense corrosion during their operation leading to a considerable loss of material and structure capacity reduction. Shaft guides are made of closed profiles welded from hot-rolled channel sections. These profiles are categorized as class 1 cross-sections according to Eurocode 3, which means that they are resistant to local instability upon bending [1]. With an increase in the corrosion loss of the guides, the inertia moment of the cross-section is reduced. The resistance of profiles to local buckling is als

Abstract:

Background: Fine Needle Aspiration Cytology (FNAC) is a very useful technique for morphological diagnosis of any tumors. It is useful in children as the chance of complication is very rare. Moreover, it is rapid, cost effective, and outpatient procedure. No anesthesia is required for this. Diagnosis can be available readily and suitable for giving preoperative chemotherapy. So FNAC plays important role in pediatric kidney tumor where neo adjuvant chemotherapy given before surgery. Guided FNAC is more reliable method than unguided FNAC. Core Needle Biopsy (CNB) is another investigation for preo

Abstract:

Dyspepsia, characterized by epigastric discomfort, postprandial fullness, and early satiety, is a common disorder affecting a significant proportion of the population worldwide. Its management hinges on appropriately distinguishing functional from organic causes—where structural lesions or malignancies may be involved. Endoscopy serves as a crucial diagnostic tool, but its utilization should be guided by patient age and the presence of alarm features to ensure optimal benefit and avoid unnecessary risks. This review discusses current evidence regarding indications, diagnostic yield, and potent

Abstract:

The ability of irradiated 55 mm diameter tryptone soya agar contact plates to recover naturally occurring surface microbial contamination, using three different manual sampling procedures, was investigated. The investigation was completed by sampling hard surfaces contaminated with microbe-carrying particles (MCPs) dispersed from a person within heavily populated environments. This is more representative of the contamination that is found within cleanrooms and avoids issues resulting from the utilisation of standard commercial test organisms to distribute unicellular microbes onto surfaces, wh

Abstract:

Introduction With a deluge of mouthwatering pre-publicity, the opening of The Spotted Pig, the USA’s first self-identified British-styled gastropub, in Manhattan in February 2004 was much anticipated. The late Australian chef, food writer and restauranteur Mietta O’Donnell has noted how “taking over a building or business which has a long established reputation can be a mixed blessing” because of the way that memories “can enrich the experience of being in a place or they can just make people nostalgic”. Bistro Le Zoo, the previous eatery on the site, had been very popular when it opened almos

In 1988, historian Nadia Wheatley and indigenous artist Donna Rawlins published their award-winning picture book, My Place, a reinterpretation of Australian national identity and sovereignty prompted by the bicentennial of white settlement. Twenty years later, the Australian Broadcasting Corporation (ABC) commissioned Penny Chapman’s multi-platform project based on this book. The 13 episodes of the television series begin in 2008, each telling the story of a child at a different point in history, and are accompanied by substantial interactive online content.

Abstract:

In light of an ongoing debate over the authorship of the Redfern address (was it then Prime Minister Paul Keating or his speechwriter, Don Watson, who was responsible for this historic piece?), the authors of this article consider notions of ownership, authorship, and acknowledgement as they relate to the crafting, delivery, and reception of historical political speeches. There is focus, too, on the often-remarkable partnership that evolves between speechwriters and those who deliver the work. We argue that by drawing on the expertise of an artist or—in the case of the article at hand—speechwr
