امروزه استفاده بیش از حد کودهای شیمیایی موجب تخریب ساختمان خاک و آلودگی آب های سطحی و زیرزمینی شده است. یکی از روشهای بهبود کیفیت خاک و حذف آلاینده های ناشی از بکارگیری کود شیمیایی، استفاده از کودهای حیوانی است که مصرف آن نقش موثری در توسعه کشاورزی پایدار دارد. از مشکلات مهم در استفاده از کودهای حیوانی نحوه ی پخش آنها در سطح مزرعه است. بدین منظور در این پژوهش به طراحی و ساخت ماشین کودپاش سانتری...

BACKGROUND Unmethylated cytosine-guanine (CpG) motif-containing oligodeoxynucleotides (ODNs) have been well characterized as agonists of Toll-like receptor 9 (TLR9). ODNs with a phosphorothioate (PTO) backbone have been studied as TLR9 agonists since natural ODNs with a phosphodiester (PD) backbone are easily degraded by a serum nuclease, which makes them problematic for therapeutic application...

Three isostructural interwoven 3,4-connected mesoporous metal-organic frameworks of pto-a topology (UTSA-28-Cu, UTSA-28-Zn, and UTSA-28-Mn) were synthesized and structurally characterized. Because of their metastable nature, their gas sorption properties are highly dependent on the metal ions and activation profiles. The most stable, UTSA-28a-Cu, exhibits promising gas storage and separation ca...

The aim of this work is to assess the influence different degrees adaptability power take-off (PTO) system on absorption dense wave energy converter (WEC) arrays. included in simulations through a transmission ratio that scales force actuating PTO relative generated by motion floater. A numerical model used which hydrodynamic interactions between floaters and nonlinearities are considered. lowe...

A mixed time-domain/frequency-domain method is proposed for modelling dense wave energy converter (WEC) arrays with non-linear power take-off (PTO). The model based on a harmonic balance which describes the system response in frequency domain, while evaluating PTO force and solving equations of motion time domain. computed Lagrange multipliers. In order to apply WEC array responses real sea sta...

Acknowledging the absence of up-to-date empirical data on the value retention, service life and annual use of chipping machinery, in 2017 the authors surveyed the records kept by 50 contractors offering biomass chipping services. The machine fleet and operations in this survey could be taken as representative for most of Europe, where the biomass sector is well established and is facing further...

The disease-specific survival (DSS) of 151 patients with chronic graft-versus-host disease (cGVHD) was studied in an attempt to stratify patients into risk groups and to form a basis for a new grading of cGVHD. The data included the outcome and 23 variables at the diagnosis of cGVHD and at the primary treatment failure (PTF). Eighty-nine patients (58%) failed primary therapy for cGVHD. Nonrelap...
