background: babesia ovis and theileria ovis are among the important and main etiological agents causing ovine babesiosis and ovine theileriosis, causing severe economic losses among sheep and goats. the aim of the present study was to determine the prevalence and molecular diagnosis of b. ovis and t. ovis in lohi sheep at livestock experiment station bahadurnagar, okara, pakistan. methods: the ...

The paper reports the synthesis and characterisation of a series of flexible di-bidentate bridging ligands in which two 4-methyl-2,2'-bipyridine groups are linked at the 4'-position by polymethylene (bb(n)), linear polyether (bbO(n)) or linear alkylamine (bbN(n)) chains of varying length (n). The enantiomers (ΔΔ/ΛΛ) of the rac forms of the ruthenium(ii) dinuclear complexes incorporating these l...

In this paper, an injection-seeded nanosecond optical parametric generation (OPG) using BBO crystal, which combines relatively low thresholds with a simple and compact configuration, was demonstrated. By seeding externally distributed feedback (DFB) diode laser at 1313 nm wavelength, pumped by 355 pulse, the maximum blue output power of 1.36 W rate 100 Hz linewidth less than 0.13 were obtained,...

Dark matter (DM) occupies the majority of content in universe and is probably cold (CDM). However, modifications to standard CDM model may be required by small-scale observations, DM self-interacting (SIDM) or warm (WDM). Here we show that diffractive lensing gravitational waves (GWs) from binary black hole mergers small halos ($\ensuremath{\sim}{10}^{3}--{10}^{6}\text{ }\text{ }{M}_{\ensuremat...

Black-box optimization (BBO) algorithms are concerned with finding the best solutions for problems missing analytical details. Most classical methods such based on strong and fixed a priori assumptions, as Gaussianity. However, complex real-world problems, especially when global optimum is desired, could be very far from assumptions because of their diversities, causing unexpected obstacles. In...
