Abstract:

The stem of the snakewood plant (Strychnos lucida) has been used empirically as a malaria drug, relieves fever, treats stomach pain, hemorrhoids, rheumatism, stroke symptoms, and improves blood circulation. Tannins as one of the secondary metabolites of snakewood stems contain gallic acid compounds which are known to thin the blood. The purpose of this study was to determine the anticoagulant activity of the ethanolic extract of snakewood stems on blood group samples, namely A, B, AB, and O.

Abstract: The period of blood coagulation is the time needed to measure the duration of blood clots. Laboratory examination generally passes through 3 stages: preanalytic, analytic and post analytic stages. At the preanalytic stage should be considered such as the use of glass tubes and plastic tubes. As well as various technical errors tend to shorten or extend the freezing period. This study aims to determine whether there is any difference in the value of clotting time by using glass and plastic tube of Lee and White method.

Abstract:

An accurate characterization of borehole seismic sources is necessary to model and interpret waveforms observed in crosshole and reverse vertical seismic profiling (VSP) surveys, since the radiation pattern of a source will directly influence the amplitudes of elastic wave arrivals at receiver locations. Any attempt to study these data or perform inversions of amplitude data without incorporating the borehole effects will have serious limitations. Most previous studies of borehole seismic source radiation patterns have applied low‐frequency approximations to develop expressions for the radiati

Abstract:

Cardiovascular disease can occur due to disruption of the hemostatic system by forming blood clots in blood vessels, or commonly known as deep vein thrombosis. The curative action that has been carried out in the form of heparin anticoagulant administration had many side effects such as bleeding, hematuria, thrombocytopenia, and hypersensitivity; therefore, alternative anticoagulant ingredients such as onion bulbs have emerged. Dayak onion bulb (Eleutherine bulbosa) is known to contain eleutherinol compound, which has anticoagulant activity. This study aims to determine the potential anticoagu

The first part of the paper presents a method for frequency domain deconvolution of airborne gamma‐ray surveys using a Wiener filter. A geometrical detector model is used to model gamma‐ray detection, with aircraft movement simply incorporated by a multiplicative term. The method requires estimation of the autocorrelation functions governing both signal and noise. The former is estimated through the radially averaged power spectrum of the survey data, whereas an error propagation analysis is used to estimate the latter, which is assumed white.

Abstract:

Laser Assisted Electrodeposition (LAE) is one of the most interesting non-conventional electroplating techniques. This advanced deposition method makes use of a laser to induce the reduction of metallic ions on the surface of a conductive substrate. Unlike Laser Enhanced Electrodeposition (LEE), which relies on an external polarization, in the case of LAE the laser provides the totality of the energy required by the deposition process. The consequent absence of the anode required to polarize the substrate makes LAE highly attractive in terms of flexibility and scalability. In addition, LAE gua

Synthetic anticoagulants such as heparin, citric, and ethylenediaminetetraacetic acid (EDTA) are commonly used to prevent blood clots.

Therefore, an alternative material that is relatively cheap, non-toxic, and easy to obtain and process in a ready-to-use form is needed. Garlic contains allicin and ajoene, which are anti-platelet and anti-thrombogenic. This study’s aim is to explore the potential of garlic filtrate as an alternative anticoagulant. Blood from 16 in

The C. elegans embryo can be used for cell tracking studies to understand how cell movement drives the development of specific embryonic tissues. Analyses in late-stage development are complicated by bouts of rapid twitching motions which invalidate traditional cell tracking approaches.
