Abstract:

Abstract A piping system is the main part of a system that connects the point where the fluid is stored to the point of accessing the pipe. Both pipe strength and pump capacity must be carefully considered because the safety of a ship will depend on the piping arrangement as well as on other ship equipment. The main function of the bilge pipe system is the drainage system in case of flooding in the compartment due to grounding or collision. Another function is the drainage system in the event of leaks on the welding root, condensation on the side shell leaks on the piping system (particularly

In 2015, research activities to modify TRIGA 2000 Reactor Bandung fuel element from cylindrical to plate-type have been initiated. By using plate-type fuel elements, core cooling process will be altered due to different generated heat distribution. The direction of cooling flow is changed from bottom-to-top natural convection to top-to-bottom forced convection. This change of flow direction requires adjustment on the cooling piping system, in order to produce simple, economical, and safe piping route.

Abstract:

Liquid in a large piping system could become a resonance column under axial excitations. A 1000-m long closed-boundaries pipeline with pressure wave propagation velocity of 1000 m/s would have the fundamental liquid resonance frequency of 0.5 Hz. Then, some hydraulic transients might occur during strong earthquakes. If dynamic pressure amplitude exceeds the value of system stationary pressure, then vaporizing at negative pressure, and after that, cavity or liquid column separation and reconnection can be produced. One of the effects of these behaviors would be equivalent damping of dynamic res

This project designed a plant that will process 250 tonnes of raw tomatoes per day. The duration of this production was spread across 24 hours and operated for 300 days in a year, which gave a yield of 17.5 tons of tomato powder per day. From these specifications, the best process route was synthesized. The process route selected involved choosing and sorting the tomatoes, washing, blanching, blending, spray drying (as the drying process), packaging and labeling. Through a series of investigations, the most feasible way to dry tomato powder on an industrial scale proved to be the spray-drying

The crossover and mutation operations are designed on the basis of this encoding as well. In case of the routing for multi pipes or pipe with branches, cooperative coevolutionary GA is adopted to route pipes harmoniou

This collision avoidance scheme is for orthogonal pipe routing and forms the basis for extension to other routing principles.

Abstract:

The transmission cycle of western equine encephalitis (WEE) virus in South America is unknown. A WEE virus strain was isolated from Aedes albifasciatus in Argentina during the WEE epizootic of 1982-83. Also, Culex pipiens from Argentina was reported to be able to transmit WEE virus experimentally, but other results indicate that Cx. pipiens from the USA is refractory to this virus. We determined the susceptibility of Argentina strains of Ae. albifasciatus and Culex pipiens complex mosquites to infection by WEE virus by the oral route. Adult females were fed on chicks infected with a WEE virus

Abstract The current work aims to improve the metal oxide characteristics for mosquito control. Un-doped and Y-doped CuO have been synthesized by simple chemical route. Structural, composition, and morphological properties were characterized by XRD, Raman spectra, EDX, SEM, and TEM techniques. The obtained results revealed that CuO was strongly affected by Y3+ support, in which the crystallite size decreased, and the surface area increased. Larvicidal performance was assessed against Culex pipiens suggesting that the nanocomposite CuO/Y of higher efficiency (LC50 = 7.67 mg /l, R2 = 0.977) comp

Abstract:

Protected cultivation in modern agriculture relies extensively on plastic-originated mulch films, nets, packaging, piping, silage, and various applications. Polyolefins synthesized from petrochemical routes are vastly consumed in plasticulture, wherein PP and PE are the dominant commodity plastics. Imposing substantial impacts on our geosphere and humankind, plastics in soil threaten food security, health, and the environment. Mismanaged plastics are not biodegradable under natural conditions and generate problematic emerging pollutants such as nano-micro plastics. Post-consumed petrochemical

Abstract:

The West Nile virus (WNV) has recently become more widespread, posing a threat to both human and animal health. In Western Europe, most outbreaks have been caused by WNV lineage 1, while in Eastern Europe, WNV lineage 2 has led to human and bird mortality. The ability to appropriately manage this threat is dependent on integrated surveillance and early detection. This study aimed to quantify the prevalence of WNV infection in mosquitoes and to identify the circulating viral lineage in eastern Croatia. Mosquito traps were set up in rural and urban areas during the 2021–2023 seasons, and the col

Abstract:

Polyethylene pipes are used in most applications for the transport and distribution of drinking water. Pipe systems generally have complex routes that include undercrossings of roads. Consequently, the pipe loads are complex, resulting from: internal fluid pressure, soil loads, traffic pressure. In a test program aimed at evaluating both the axial stress behavior and the mechanical characteristics of polyethylene pipes used in the construction of water distribution piping systems, in the presence of defects, theoretical and experimental research was carried out.

In May-June 2002, as part of a survey of a variety of taxa in the James Bay region of Ontario and Québec, we surveyed the poorly documented herpetofauna of this region. In Ontario we visited sites near Moosonee that FWS had previously surveyed in 1971-1972, and continued ongoing herpetological monitoring around Cochrane. In Québec we surveyed the inland James Bay Road, and roads to four settlements along the coast. American Toad (Anaxyrus americanus), Spring Peeper (Pseudacris crucifer), and Wood Frog (Lithobates sylvaticus) were widespread and abundant throughout. Blue-spotted Salamander (Amb

Abstract:

The lemon grass palladium metallic nanoparticles (NPs) are 20 ±1 nm in size, oval shape, and can enter a cell via a plasma membrane. The essential lipid bilayer is primarily composed of proteins and lipids. The protein portion of the membrane facilitates the transport of any molecules from the outside to the inside of the cell. The transport form of proteins is called transptransporters, ion channels that allow molecules inside the cell. The nanoparticle also follows the same route to enter the cell and pass through protein structures. Once the NPs enter the cell, they initiate their ac

Abstract:

An animal's capacity to recolonize a patch depends on at least two components: its ability to detect the patch and its ability to reach it. However, the disruption of such processes by anthropic disturbances could explain low animal abundance patterns observed by many investigators in certain landscapes. Through field experiments, we compared the orientation and homing success of northern green frogs (Rana clamitans melanota Rafinesque, 1820) and northern leopard frogs (Rana pipiens Schreber, 1782) translocated across disturbed or undisturbed surfaces. We also monitored the path selected by in

Abstract:

Rift Valley fever (RVF) is a zoonotic disease caused by a virus mainly transmitted by Aedes and Culex mosquitoes. Infection leads to high abortion rates and considerable mortality in domestic livestock. The combination of viral circulation in Egypt and Libya and the existence of unregulated live animal trade routes through endemic areas raise concerns that the virus may spread to other Mediterranean countries, where there are mosquitoes potentially competent for RVF virus (RVFV) transmission. The competence of vectors for a given pathogen can be assessed through laboratory experiments, but res

Isotopic methodology was used to characterize Cl- transport in isolated epithelia of frog skin (northern Rana pipiens) bathed in Cl--rich Ringer solution and short-circuited. Cl- content of epithelia measured when loaded to 36Cl specific activity equilibrium averaged 139.6 neq/mg dry wt. The kinetics of 36Cl efflux was biexponential and consistent with binding or compartmentalization of approximately 30% of tissue Cl- within the intracellular pool. Because efflux of 36Cl to the apical solution was immeasurable, it was concluded that apical membranes were virtually impermeable to Cl- and that b

Abstract:

In mosquitoes, the utilization of RNAi for functional genetics is widespread, usually mediated through introduced double-stranded RNAs (dsRNAs) with sequence identity to a gene of interest. However, RNAi in mosquitoes is often hampered by inconsistencies in target gene knockdown between experimental setups. While the core RNAi pathway is known to function in most mosquito strains, the uptake and biodistribution of dsRNAs across different mosquito species and life stages have yet to be extensively explored as a source of variation in RNAi experiments.
