Local vessel wall shear stress is considered to be important for vessel growth. This study is a theoretical investigation of how this mechanism contributes to the structure of a vascular network. The analyses and simulations were performed on vascular networks of increasing complexity, ranging from single-vessel resistance to large hexagonal networks. These networks were perfused by constant-flow sources, constant-pressure sources, or pressure sources with internal resistances. The mathematical foundation of the local endothelial shear stress and vessel wall adaptation was as follows: delta d/

We have examined effects of vasodilator stimuli on segmental resistance in the cerebral circulation. Our hypothesis was that resistance of large arteries, as well as small vessels, contributes to cerebral vascular responses to vasodilator stimuli. We measured cerebral blood flow with microspheres in anesthetized rabbits and measured pressure in pial arteries approximately 100 microns diameter using a servo-null method. These values were used to calculate resistance of large arteries (greater than 100 microns diameter) and small vessels (less than 100 microns diameter). Under control conditions

Abstract A bulbous bow is a widely employed feature to enhance the hydrodynamic resistance of ships. More than 95% of the merchant fleet incorporates various types of bulbous bows to reduce wave-making resistance and wave breaking. Bulbous bow is also utilized in smaller vessels like fishing vessels. In certain cases, the initial ship design includes the addition of a bulbous bow by default. In this study, which focuses on a typical Argentinian trawler fishing vessel, we investigate the impact of the bulbous bow on resistance.

Abstract Morphological traits of the plant vascular system such as xylem vessel diameter have been implicated in many physiological processes including resistance to drought-induced xylem cavitation and vessel occlusion during infection with vascular wilt diseases. In both events, xylem vessels lose function because they become filled with air or tyloses and gels. Xylem cavitation has been well studied, whereas vessel occlusion remains purely descriptive even though it is a critical response to wounding injuries and compartmentalization of vascular pathogens.

Histamine's effect on the longitudinal resistance and compliance distribution in the canine pulmonary circulation was determined under control and elevated vascular tone using the thromboxane analogue U46619. The arterial-, venous-, and double-occlusion techniques were used in isolated blood-perfused dog lungs at both constant flow and constant pressure. Large and small blood vessel resistances and compliances were studied in lungs given the following treatments: 1) histamine; 2) histamine in lungs pretreated with the H1-receptor antagonist diphenhydramine, and 3) histamine in lungs pretreated

<strong><em>Abstract</em></strong><strong>—</strong> <em>In general, fishing fleets operating in Maluku waters and managed by local entrepreneurs consist of mono hull fishing vessels (such as purse seines, etc.) and trimaran in chart form. These two types of fishing fleets have been known to the people of Maluku for a long time. However, these two types each have their advantages and limitations, for example, mono hull fishing boats have limited deck space and poor transverse stability, especially in bumpy sea conditions in extreme weather. While the trimaran type has better deck space a

Trimaran hull form as multihull ship becomes more attractive these days in various ship types. It offers more advantages in terms of seakeeping performances, particularly on the application of a fishing vessel. However, thus far, the conventional design of fishing vessels is not favorable to ensure the safety of a vessel sailing in a rough sea. In conjunction with such issues, we discuss a trimaran fishing vessel design based on the seakeeping criterion to evaluate the dynamic stability, ship motion RAOs, and ship resistances at the initial design stages using linear strip theory.

Indonesia is a maritime country with two-thirds of its territory is the ocean. Indonesia has a diversity of marine resources with a total fish production continuing each year to reach 8.02 million tons. The traditional fishing vessel is one of transportation and livelihood support in Indonesia and the vessel was made based on the knowledge from generation to generation. Thus, the investigation of the fishing vessels must be conducted to measure the resistance profile and wave pattern. This analysis is conducted to consider the mono-hull fishing vessel design.

As a result of the high specific strength/stiffness to mass ratio, filament wound composite pressure vessels are extensively used to contain gas or fluid under pressure. The ability to in-situ monitor the composite pressure vessels for possible damage is important for high-pressure medium storage industries. This paper describes an in-situ monitoring method to permanently monitor composite pressure vessels for their structural integrity. The sensor is made of a multi-walled carbon nanotube (MWCNT) that can be embedded in the composite skin of the pressure vessels. The sensing ability of the se

Abstract In this article is presented the methodology of calculation of principal parameters of hull a vessel and resistance components. The approximate method is based on the analysis of the results of model tests and surrender tests presented in the literature. Ship owners' preliminary assumptions for new ship consist of deadweight, speed-shipping line and others. This goal needs definition of principal dimensions of a vessel, which are the basis for further calculations of hull’s resistance and evaluation of necessary power of main engine to fulfil shipping requirements.

The objectives of this study were to evaluate the myogenic behavior of blood vessels and their interaction within the coronary arterial tree and to evaluate the possible role of the myogenic response in autoregulation. The model consists of 10 compartments in series, each representing a class of vessel sizes. Diameter and resistance in each class are determined by their value at full dilation ( d p, R p) and by the myogenic response. Three distributions of R p and three distributions of myogenic strength, M i (slope of pressure-diameter curve, range −0.05 to −0.4%/mmHg) were evaluated (9 cases

The study of the effect of leukocyte adhesion on blood flow in small vessels is of primary interest to understand the resistance changes in venular microcirculation. Available computational fluid dynamic studies provide information on the effect of leukocyte adhesion when blood is considered as a homogeneous Newtonian fluid. In the present work we aim to understand the effect of leukocyte adhesion on the non‐Newtonian Casson fluid flow of blood in small venules; the Casson model represents the effect of red blood cell aggregation. In our model the blood vessel is considered as a circular cylin

Metastasis is the primary cause of cancer-related mortality. Cancer cells primarily metastasize via blood and lymphatic vessels to colonize lymph nodes and distant organs, leading to worse prognosis. Thus, strategies to limit blood and lymphatic spread of cancer have been a focal point of cancer research for several decades. Resistance to FDA-approved anti-angiogenic therapies designed to limit blood vessel growth has emerged as a significant clinical challenge. However, there are no FDA-approved drugs that target tumor lymphangiogenesis, despite the consequences of metastasis through the lymp

The characteristics of the blood vessel are analysed and simplified, and the resistance reduction effects of three bionic microstructure models, namely V-shaped, rectangular and semi-circular, are compared and analysed by numerical simulations, and the resistance reduction effects of the three groove structures in the tubular model are verified. The results show that the V-shaped groove structure occupies a smaller volume compared to the rectangular and semi-circul

Today the most crucial aspect in the preliminary vessel design stage is to make it as green/blue as possible. One of the exciting goals is the minimisation of vessel resistance. The use of hydrofoils to reduce the vessel draught and consequently, reduction in the vessel resistance is today one of the hottest design topics, especially for catamaran passenger vessels. In the present work, we discuss the issues related to the implementation of Isogeometric Analysis (IGA) Boundary Element Method (BEM) for the calculation of the hydrodynamic properties of lifting hydrofoils.

To explore possible longitudinal variations in response sidedness, we compared reactivity of isolated vessels from carotid arteries to first-order arterioles. Concentration-response curves for luminally or adventitially applied phenylephrine (PE) were constructed. Arterioles were 274-fold less responsive when PE was in luminal vs. adventitial responsiveness decreased as vessel diameters increased, from 24-fold in inferior saccular arteries to 18-fold in exte

<em>The type of fishing vessel that is widely used by fishermen in North Sulawesi, especially in the Bitung Coast, is a pelagic fishing vessel. When the ship sails at a certain speed, it will experience resistance in the form of resistance. This resistance will cause some speed drops. This will result in losses to the ship, including the time it takes when the ship performs maneuvers to catch schools of fish, extending the sailing time so that fuel consumption becomes greater and the use of working hours becomes longer, which means the cost of exploitation of the ship becomes greater.</em> <em

The vessels from both groups, when activated by 80 mM K+, were unaffected by AP III. However, activation of WKY vessels by 10(-4) M NE (both phasic and tonic contraction) was inhibited quite effectively and potently by AP III, whereas that in SHR vessels was much le
