Abstract:

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/

The article presents the theoretical substantiation of using the optimal trim of “river- sea” vessels in order to improve the propulsion of vessels of various types and purposes navigating on seas and rivers. There has been carried out the analysis of the optimal trim for different types of ships in operation. The given calculations prove the possibility of designing new ships with improved sailing characteristics. The scheme of damping the bow shear wave coming from the stem of the “river-sea” vessel is illustrated using the shear wave coming from the bow bulb, with a differential to the bow.

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

Protection of marine environment and reduction of GHG emissions are currently imperative criterion for ship design. For ships in service, including fishing vessels powered by internal combustion engines, options of retrofitting are sought to reduce their hydrodynamic resistance and fuel consumption. One such possibility is the addition of a simple-shape bulbous bow, which can be installed at low cost to upgrade a fishing vessel.

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.

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.

<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

Abstract:

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.

Abstract:

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.

Abstract:

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

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

Abstract:

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 use of bionic drag-reducing microstructures in artificial blood vessels can effectively reduce their resistance to blood flow. 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.

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

Abstract:

<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 effects of atriopeptin III (AP III) were determined on agonist-induced [i.e., 10(-4) M norepinephrine (NE)] and depolarization-induced (80 mM K+) contractions of isolated mesenteric resistance vessels (ID approximately 100 microns) from spontaneously hypertensive rats (SHR) and from normotensive control Wistar-Kyoto (WKY) rats. 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
