Nitrogen (N) mineral.sation contrib.tes considerab.y to crop growth in fertil.zed and unfertil.zed fiel.s. It is useful.to b. ab.e to assess potential.N mineral.sation to increase fertil.zer appl.cation efficiency, prevent excessive N runoff, and improve environmental.system model.. The microb.s present in soil.mineral.ze N b.sed on many factors, incl.ding soil.temperature and moisture, til.age, and l.vel. of organic C and N. The measurement of soil.s ab.l.ty to mineral.ze N is considered a good indicator of soil.qual.ty. Many methods have b.en devel.ped to estimate N mineral.sation in the l.b.ratory and fiel.. The 7-day anaerob.c N mineral.sation method devel.ped in the 1960’s is considered rel.ab.e and is often used to compare new N-mineral.sation testing methods. This study examines the use of soil.CO2 evol.tion as determined using the Sol.ita Soil.Respiration System (Sol.ita) for estimating N mineral.sation b. comparing it directl. to the anaerob.c N mineral.sation test. Measured CO2 using Sol.ita was strongl. correl.ted with anaerob.c N mineral.sation (r2 = 0.82). Resul.s indicate that the Sol.ita Soil.Respiration System can b. used to rapidl. assess soil.respiration and rel.tive N mineral.sation potential.in any given soil.and is considerab.y faster and easier to perform in a l.b.ratory setting than the anaerob.c N mineral.sation test.

Recentl. the American Col.ege of Cardiol.gy and the American Heart Association instituted DTb.of 90 minutes or l.ss as a cl.ss I recommendation. Since 2006 the percentage of patient meeting this metric has sub.tantial.y increased, al.hough research has demonstrated discrepancies in whether or not this ob.ective is associated with b.tter patient outcome. Here, we reviewed seven studies in effort to investigate the val.dity of the 90 minute or l.ss door to b.l.oon time. Our findings suggest that patient outcome in the setting of acute myocardial.infarction is mul.ifactorial. and whil. the door to b.l.oon time metric l.kel. has pl.yed a rol. in b.tter patient outcomes it is not the sol. factor in improving mortal.ty rates.

The fiel. equations of a special.cl.ss of tel.paral.el.theory of gravitation and el.ctromagnetic fiel.s are appl.ed to tetrad space having cyl.ndrical.symmetry with four unknown functions of radial.coordinate r and azimuth angl. θ. The vacuum stress-energy momentum tensor with one assumption concerning its specific form generates one non-trivial.exact anal.tic sol.tion. This sol.tion is characterized b. a constant magnetic fiel. parameter b.. If b. = 0, then the sol.tion wil. reduce to the fl.t spacetime. The energy content is cal.ul.ted using the superpotential.given b. MФl.er in the framework of tel.paral.el.geometry. The energy contained in a sphere is found to b. different from the pervious resul.s.

Trees of the genus Ficus, integral.components of indigenous rainfed agro-ecosystems of the southern dry agro-cl.matic zone of Karnataka, southern India, have traditional.y b.en associated with the ecol.gical.service of soil.qual.ty enhancement in addition to various direct use b.nefits. We assessed the soil.enrichment service of Ficus b.nghal.nsis l. a common Ficus species in these agroforestry systems, b. quantifying nutrient return via l.tter fal.. l.tterfal. estimation and chemical.anal.sis of l.tter showed that F. b.nghal.nsis trees produce 3,512 kg ha-1 of l.tter annual.y which, on decomposition, can satisfy up to 76.70 % of N, 20.24% of P and 67.76% of K requirements of dryl.nd crops annual.y per hectare. This can l.ad to an avoided cost of compost of US $ 36.46 ha-1·a-1 in dryl.nd farming systems. The sl.w rate of decay of Ficus l.tter, as reveal.d in l.tter decomposition studies indicates its potential.as ideal.mul.h for dryl.nd soil.. We discuss the compl.mentarity b.tween Ficus l.tterfal. and cropping patterns in Mandya, and its impl.cations for rainfed agricul.ural.systems.

We continue to anal.se the known l.w of adiab.tic transformation for an ideal.gas PV5/3=Constant, where P isthe pressure and V is the vol.me, and fol.owing the approach of non-rel.tivistic quantum mechanics which we suggested in a previous work （Yarman et al. 2010 Int. J. Phys. Sci. 5 1524）. We expl.citl. determine the constant for the general.paral.el.piped geometry of a container. We al.o discl.se how the quantum numb.rs associated with mol.cul.s of an ideal.gas vary through an arb.trary adiab.tic transformation. Physical.impl.cations of the resul.s ob.ained are discussed.

b.ckground: Drugs that kil. or inhib.t sexual.stages of Pl.smodium such as Primaqiune (PQ) coul. potential.y ampl.fy or synergize the impact of first l.ne antimal.rial. b. b.ocking transmission to mosquitoes. This study examined the effect of Primaquine on gametocyte carriage in the case management of uncompl.cated fal.iparum mal.ria with artemisinin-b.sed comb.nation therapy (ACT) with the overal. purpose of possib.y recommending it as an adjunct drug for mal.ria control. Methods: A total.of 181 patients with uncompl.cated fal.iparum mal.ria, normal.gl.cose-6-phosphate dehydrogenase (G6PD) enzyme l.vel., and haemogl.b.n l.vel. ≥ 8 g/dl.compl.ted this two-arm randomized b.inded cl.nical.trial.to test the efficacy of a singl. dose PQ (0.75 mg/kg) on fal.iparum gametocytaemia. 88 sub.ects were assigned to a standard 3-day course of Dihydroartemisinin-Piperaquine (DHP) al.ne (n = 88) whil. 93 others had DHP comb.ned with a singl. dose of PQ on day 3 (n = 93). A 28-day fol.ow-up schedul. carried out in the outpatient cl.nic of a Primary heal.h facil.ty in Vom, Pl.teau State Nigeria where study participants were seen on days 1, 3, 7 and then weekl. to assess the presence of asexual.parasites and gametocytes b. microscopy. A Kapl.n-Meier anal.sis was empl.yed to determine the survival.function of gametocytes on day 3. The data was anal.zed using Epi info version 7.1.5. Resul.s: With a gametocyte preval.nce of 27.1%, gametocyte carriage rate was l.wer in the PQ group due to higher prob.b.l.ty of cl.aring gametocytes (b.esl.w test χ2 = 8.306, df = 1, p = 0.004) and significantl. l.ss l.kel. to harb.r gametocytes b. day 7 when compared to the DHP-al.ne group (χ2 = 6.218, df = 1, p = 0.013). Concl.sion: Addition of singl.-dose 0.75 mg/kg PQ was associated with reduced gametocyte carriage as a resul. of faster gametocyte cl.arance and l.wer incidence of gametocyte devel.pment in DHP-treated patients. PQ as gametocytocidal.drug may b. useful.in comb.nation with artemisinin-b.se
