And Function

In addition to electrical design and function, corrosion resistance is an important factor in producing earth rod and plate which indicate quality of these products. The ability of an electrical grounding component to resist corrosion determines its service life.Different production methods has been tried to reach the maximum corrosion resistance but electro deposition process specially alloyed covering used in this research is the most successful method. In this research innovation of the invented process is described, then to confirm the method, corrosion resistance of the covered Earth rod and plate is tested. Phenomenal results indicated that even with 100 micron thickness of the new coating layer, corrosion resistance reaches the required time of resistance. Also by increasing the layer thickness, corrosion resistance is increased.

Galvanic Deposition

Galvanic deposition of Aluminium on steel substrate, starting from liquid ions, is considered. How the agitation of the liquid during deposition influences the homogeneity of the developed coating layer is investigated by a commercially available FLUENT® ANSYS® solver. Comparison of data coming from numerical simulation with experimentally obtained results are presented. The reported results demonstrate that the deposition process parameter influences the quality of the deposited aluminium.

GaAs layers grown by MBE at low temperatures (in the 200°C range, LT-GaAs) have been reported to have very interesting electronic and transport properties. Previous studies have shown that, before annealing, the crystalline quality of the layers is related to the growth temperature. Lowering the temperature or increasing the layer thickness generally results in some columnar polycrystalline growth. For the best “temperature-thickness” combinations, the layers may be very As rich (up to 1.25%) resulting in an up to 0.15% increase of the lattice parameter, consistent with the excess As. Only after annealing are the technologically important semi-insulating properties of these layers observed. When annealed in As atmosphere at about 600°C a decrease of the lattice parameter to the substrate value is observed. TEM studies show formation of precipitates which are supposed to be As related since the average As concentration remains almost unchanged upon annealing.

Correct Structure

Purpose Craniofacial anomalies (CFA) often result in growth abnormalities of the facial skeleton adversely affecting function and appearance. The functional problems caused by the structural anomalies include upper airway obstruction, speech abnormalities, feeding difficulty, hearing deficits, dental/occlusal defects, and cognitive and psychosocial impairment. Managing disorders of the craniofacial skeleton has been improved by the technique known as distraction osteogenesis (DO). In DO, new bone growth is stimulated allowing bones to be lengthened without need for bone graft. The purpose of this clinical focus article is to describe the technique and clinical applications and outcomes of DO in CFA. Conclusion Distraction can be applied to various regions of the craniofacial skeleton to correct structure and function. The benefits of this procedure include improved airway, feeding, occlusion, speech, and appearance, resulting in a better quality of life for patients with CFA.

Swallow Function

Lung cancer is one of the most commonly diagnosed cancers across Northern America and Europe. Treatment options offered are dependent on the type of cancer, the location of the tumor, the staging, and the overall health of the person. When surgery for lung cancer is offered, difficulty swallowing is a potential complication that can have several influencing factors. Surgical interaction with the recurrent laryngeal nerve (RLN) can lead to unilateral vocal cord palsy, altering swallow function and safety. Understanding whether the RLN has been preserved, damaged, or sacrificed is integral to understanding the effect on the swallow and the subsequent treatment options available. There is also the risk of post-surgical reduction of physiological reserve, which can reduce the strength and function of the swallow in addition to any surgery specific complications. As lung cancer has a limited prognosis, the clinician must also factor in the palliative phase, as this can further increase the burden of an already compromised swallow. By understanding the surgery and the implications this may have for the swallow, there is the potential to reduce the impact of post-surgical complications and so improve quality of life (QOL) for people with lung cancer.

Abstract In Poland, the last 15 years have been marked by various, numerous regeneration projects of historic cities that were supposed to improve the citizens quality of life and their security, as well as to create an attractive tourist offer. Those programs were often focused on the renewal, reshape and modernization of public squares. Such changes never go unnoticed. On contrary, these are frequently associated with criticism, debate and disagreements. The research has been focused on the analysis of regeneration projects from selected Market Squares in historic cities and town centres in Lower Silesia. The main aim was to exhibit the medieval origin of those squares and recently introduced contemporary layout. Moreover it was to present diverse opinions regarding square’s form and function, that can be crucial in understanding the architects, planners and citizens’ points of view and their ‘feelings’ towards the space.

Generally, interactions at surface asperities are the cause of wear. Two-Thirds of wear in industry occurs because of the abrasive or adhesive mechanisms. This research presents an analytical model for abrasion of additive manufactured Digital Light Processing products using pin-on-disk method. Particularly, the relationship between abrasion volume, normal load, and surface asperities’ angle is investigated. To verify the proposed mathematical model, the results of this model are verified with the practical experiments. Results show that the most influential parameters on abrasion rate are normal load and surface’s normal angle. Abrasion value increases linearly with increasing normal load. The maximum abrasion value occurs when the surface’s normal angle during fabrication is 45°. After the asperities are worn the abrasion volume is the same for all specimens with different surface’s normal angle. Though layer thickness does not directly affect the wear rate, but surface roughness tests show that layer thickness has a great impact on the quality of the abraded surface. When the thickness of the layers is high, the abraded surface has deeper valleys, and thus has a more negative skewness. This paper presents an original approach in abrasion behavior improvement of DLP parts which no research has been done on it so far; thus, bringing the AM one step closer to maturity.
