Abstract:

Vein detection is an important issue for the medical field. There are some commercial devices for detecting veins using infrared radiation. However, most of these commercial solutions are cost-prohibitive. Recently, veins detection has attracted much attention from research teams. The main focus is on developing real-time systems with low-cost hardware. Systems developed to reduce costs suffer from low frame rates. This, in turn, makes these systems not suitable for real-world applications. On the other hand, systems that use powerful processors to produce high frame rates suffer from high cos

Abstract:

Note on the stable isotope values of vein calcite in the El-Seboah peralkaline granite (SW Egypt)Stable isotope data for carbon (δ13C) and oxygen (δ18O) are used to constrain the environments of calcite formation in two veins in the El-Seboah peralkaline granite in south-western Egypt. Vein I with calcite-magnetite-goethite-hematite-quartz, and vein II with calcite-magnetite-goethite-kaolinite-hematite-quartz are texturally distinct. The calcite of each vein has characteristic δ13C- and δ18O-values: + 0.32 and -7.28‰ for vein I and + 1.16 and - 1.21‰ for vein II, respectively. The observed dif

Abstract:

SummaryOverall, aneurysms of the venous system constitute a rare disease. Up to March 2016, 1,199 venous aneurysms at various locations had been reported in the literature. The most common were aneurysms of the extrahepatic portal vein (n=247), followed by popliteal venous aneurysms (n=223) and, in third place, aneurysms of the internal or external jugular vein (n=143). Venous aneurysms are not usually diagnosed until they have become symptomatic or have led to complications, such as thrombosis and/or pulmonary embolism. First-line treatment of symptomatic aneurysms is resection of the aneurys

Abstract:

The superficial veins of the forelimb show high variability, both in man and in other primates, regarding the number of main venous trunks, their course, as well as the origin and location of openings. The distinction between two venous systems–the superficial and deep was made based on the relation of specific venous channels to the deep fascia; both groups of veins anastomose to each other through perforators piercing the deep fascia. In our work, we paid special attention to the organization of the venous system within the forelimb of the Anubis baboon (Papio anubis), as well as communicati

Abstract:

We have directly demonstrated that the mesenteric veins actively constrict and dilate in response to reflex stimuli in the in situ preparation. A segment of small intestine of 23 chloralose-anesthetized rabbits was exposed in a specially designed bath. Small vein diameter and intravenous pressure (575-1,375 microns and 6.2-11.4 mmHg at rest, respectively) of the mesentery were measured continuously at the same site with the use of videomicrometer and micropressure systems during celiac ganglion stimulation (CGS), bilateral carotid occlusion (BCO), and aortic nerve stimulation (ANS).

Abstract:

The Uinta Basin of northeastern Utah contains a wide variety of hydrocarbon resources including vast accumulations of crude oil and natural gas deposits, one of the largest oil shale resources in the world, and the largest tar sand deposit in the United States. In addition, unique solid hydrocarbons, including gilsonite, wurtzilite, tabbyite, and ozokerite, have a long and colorful history of exploration and/or production in the region. The most abundant of these, gilsonite, occurs in distinctive swarms of subparallel, northwest-trending veins. The lateral continuity of the veins is impressive

Abstract:

AbstractThe textural and paragenetic relationships of sulphide and sulphosalt minerals within Cu-Pb-Sb-Bi hydrothermal vein mineralization at the Apollo mine, Siegerland, Germany, are interpreted in terms of various reaction sequences. An earlier primary sulphide mineralization hosted within a siderite vein of the Siegerland type, with pyrite, chalcopyrite, sphalerite and galena as main component phases, has been overprinted by Sb-, Bi- and Cu-rich fluids. This superposition resulted in the formation of new quartz-stibnite veins, and various mineral reactions with the primary sulphides includi

Abstract:

Two types of venation in leaves of eucalypts and other members of Myrtaceae are described and their ontogeny investigated in species of Eucalyptus. Primary seedling leaves of eucalypts have brochidodromous venation. A paramarginal vein is formed from the extensions of primary lateral veins and completed by the strengthening of commissural minor veins. Adult Eucalyptus leaves have intramarginal veins that are formed independently of the primary laterals which join them after their formation. The apparently brochidodromous venation of leaves of some species arises as a result of differential gro

Abstract:

Phlebography of the popliteal vein is reviewed. An anatomical summary considers the superficial and deep venous systems, perforating veins and the gastrocnemius veins. Techniques and methods are described. Results of 2500 investigations are reported To date the puncture failure rate is only 0.3%. The method is useful in identifying incompetence in a wide variety of veins, varicose veins and post-phlebitic disease. The system is compared to other types of investigation. It is concluded that the technique enables a rapid evaluation of venous pathology in many instances and is ideal for use on ou

Abstract:

An unusual systemic arteriovenous malformation arising from the left 9th intercostal artery, taking a caudal course through the left paravertebral veins, eventually drained into the left ascending lumbar vein, as illustrated at computed tomography and angiography. An embryologic maldevelopment of the azygos venous system is not the only possible explanation for venous drainage in the caudal direction. We believe that predominant venous drainage can take place in either direction because of the potentially bidirectional flow in the vertebral venous systems.

Abstract:

Finger-vein recognition, which is one of the conventional biometrics, hinders fake attacks, is cheaper, and it features a higher level of user-convenience than other biometrics because it uses miniaturized devices. However, the recognition performance of finger-vein recognition methods may decrease due to a variety of factors, such as image misalignment that is caused by finger position changes during image acquisition or illumination variation caused by non-uniform near-infrared (NIR) light. To solve such problems, multimodal biometric systems that are able to simultaneously recognize both fi
