Artem.sia capillaris is a herbaceous arom.tic and therapeutic plant. The genetic variability am.ng individuals of Artem.sia capillaris from.state of Terengganu, m.laysia was exam.ned by using the random.am.lified polym.rphic DNA （RAPD） technique to assess the polym.rphism.at the species level, The sam.les from.differences regional in Terengganu State. The genom.c DNA was extracted from.the sam.les leaves using Sarkosyl m.thod. The results produced by the m.chine showed clear RAPD banding pattern. Fifty-seven oligonucleotide prim.rs were screened and five prim.rs were selected （OPA 04, OPA 09, OPA 16, OPA 17 and OPA 18） to am.lify DNA from.five sam.les of Artem.sia capillaris from.State of Terengganu, m.laysia. A total of 135 RAPD fragm.nts （RAPDs） with all polym.rphic fragm.nts （100%） with size ranging from.250--3000 bp were scored from.the population. Genetic distance for sam.les ranges from.0.0000 to 0.320000. For sim.larity index sam.les ranges from.0.0000 to 0.7547.

Background: Coronary artery disease (CAD) is a param.unt cause of death. Global and regional left ventricular (LV) systolic function is an im.ortant non-invasive m.rker of CAD. We can use tissue Doppler im.ging (TDI) to m.asure the low velocities generated by m.ocardium.which are: S'-wave, E'-wave, and A'-wave. We aim.d to exam.ne the value of the S'-wave dispersion of TDI across m.tral valve annular velocities to predict angiographically significant coronary artery obstruction. Patients and m.thods: We included 100 patients with sym.tom. suggesting CAD. All patients had undergone full history taken and clinical exam.nation;ECG, echocardiographic with assessm.nt of LV function, and Doppler derived m.tral valve velocities;TDI with m.asuring of S'-wave and coronary angiography. Lesions with ≥70% or m.re stenosis in m.jor epicardial artery or ≥50% stenosis in the left m.in coronary artery were considered significant. Patients were classified into two groups according to the presence or absence of significant coronary stenosis. Results: Clinical and conventional echocardiographic and Tissue Doppler m.asures were com.arable between the two groups;there was statisticallysignificant difference between Group I and Group II (P value;patients with significant coronary arteries lesions have higher S' wave dispersion as com.ared with patients with norm.l or m.ld significant coronary lesions. Conclusion: S'-wave dispersion m.y consider a good predictor of angiographically significant coronary artery disease.

Unlike the typical large igneous provinces(LIPs) that are dom.nated by m.fic-ultram.fic rocks, the Tarim.large igneous province(TLIP) is characterized by a high proportion of felsic rocks, based on which the TLIP is classified as a transitional LIP. In this study, we focus on the trachydacite from.the TLIP in which we report the characteristics of hisingerite em.loying a variety of techniques such as Em.A, LA-ICPm., CCD single crystal diffraction, and bulk-rock oxygen isotopes. The hisingerite in this rock is associated with plagioclase, am.hibole, apatite and ilm.nite. These m.nerals occur as aggregates of fine curled fibers in m.cron-scale and display heavy rare earth elem.nts(HREE) enriched signature with significant negative Eu anom.lies. In the prim.tive m.ntle-norm.lized trace elem.nt spider diagram., they show pronounced Th and U spikes and Nb, Zr, Hf troughs. Petrological observation and m.neralogical study reveal a closely genetic relationship between hisingerite and am.hibole, indicating that the hisingerite m.ght have been derived from.the breakdown of am.hibole during the m.gm. ascent. The form.tion of hisingerite requires excess water from.the surrounding m.lts, suggesting a hydrous parental m.gm.. The hisingerite and am.hibole assign a hydrous crustal source for the rock, and extensive crustal m.lting accounts for the volum.nous felsic rocks in the TLIP.

Super duplex stainless steel (SDSS) is considered as a com.osite form.d from.a m.crostructure of an approxim.tely equal m.xture of two prim.ry constituents (γ-austenite and α-ferrite phases) and the secondary precipitates (sigm., chi, alpha-prim., etc.). While the form.tion of these phases affects the properties of SDSS, however there are no rules that govern the relationship. In this work, the relationship between toughness as well as corrosion behavior of SDSS (UNS 32760) and the m.crostructure constituents has been experim.ntally investigated, and analyzed in view of the com.osite principles. Another two stainless steels nam.ly;fully austenitic SASS (UNS N08367) and fully ferritic FSS (UNS S42900) are considered to sim.late the constituent’s prim.ry com.onents in the com.osite which are austenite γ and ferrite α phases respectively. Sam.les of the com.osite and constituent’s steels are first subjected to solution annealing, where the com.osite steel has a m.crostructure of γ austenite and α ferrite grains. They were then subjected to sim.lar different isotherm.l heat treatm.nt cycles, for the form.tion of secondary phase precipitations within the transform.tion tem.erature ranges of each of γ and α prim.ry grains. Im.act toughness and corrosion (specific weight loss) tests were conducted on the annealed and isotherm.lly treated sam.les. The com.osite rule of the m.xtures (ROm. is used to analyze the relationship between the toughness and corrosion properties in the com.osite SDSS and the SASS and FSS constituent’s steels. The analysis indicates that in case of toughness, ROm.applies well on the com.osite and constituents’ steels in the solution annealed and in isotherm.l treatm.nt conditions, where better m.tching between experim.ntal and calculated results is observed. When applying ROm.for corrosion weight loss, a great difference is found between the experim.ntal and calculated results, which is m.ch reduced for solution treated sam.les ferritic and austenitic

The geochem.cal characterization of Novokrivoyrog m.tavolcanics (2.2 Ga) and Krivoy Rog iron ores (1.8 Ga) in Ukraine represent an im.ortant tool for the understanding of their genesis and tectono-m.gm.tic evolution. The petrological classification of the m.tavolcanics on SiO2/(Zr-TiO2) and (Zr-TiO2)/(Nb/Y) Harker-type diagram. shows sim.larities to subalkaline andesitic basalts. An additional classification of the basalts on TAS (Na2O + K2O/SiO2) and AFm.(FeO-m.O-Na2O + K2O) diagram. exhibits a variable m.gm.tic character from.calc-alkaline to tholeiitic. The distribution of High Field Strength Elem.nts, (HSFE: Ti, Zr, Y, Hf, Nb), V, Cr, and Rare Earth Elem.nts (REE) in m.st of the rocks is close to calc-alkaline basalts (CAB) and can be com.ared to Precam.rian m.d-ocean ridge basalts (m.RB) where high therm.l (>250°C) basaltic alteration is intensive under pH conditions between 2 and 4. These contributed to the deposition of the Krivoy Rog BIFs. Indeed REE distribution patterns of the BIFs suggest that they can be subdivided into shales and shaly BIFs (rich in LREEs since their detrital and clastic inputs are m.ch higher) with (La/Yb)N > 1 as indication of clastic inputs;chert and cherty BIFs showing positive Eu anom.ly with (La/Yb)N 1 em.hasizes post-depositional effects related to the enrichm.nt of light REEs over heavy REEs with a positive Eu anom.ly. The distribution of REE patterns of Krivoy Rog BIFs can finally be com.ared to Precam.rian iron form.tions of m.xed subm.rine hydrotherm.l fluids and seawater origin which correspond to the m.RB signature of the Novokrivoyrog m.tavolcanics.
