Abstract Organic fertilization in orchards aims at increasing soil fertility, impacting plant productivity and environmental sustainability. This study aimed verifying the effects of organic fruit load on two nectarine cultivars with high low loads. The experiment was carried out an orchard under management Fratta Terme, Po valley, northeastern Italy. Nectarine Big Top Carene, implemented 2017 ...

Lower concentration of glucose was often obtained from enzymatic hydrolysis process of agricultural residue due to complexity of the biomass structure and properties. High substrate load feed into the hydrolysis system might solve this problem but has several other drawbacks such as low rate of reaction. In the present study, we have attempted to enhance glucose recovery from agricultural waste...

The complementary variational problems for finite plasticity with strainhardening effect are developed in this paper based on the theory of convex analysis. A new lower bound theorem for the load intensity factor, in which the plastic yield condition is relaxed by a complementary plastic superpotential, is proved. A simple illustrative example is worked out.

Carbon mat thermoplastics (CMT) consisting of 12.7 mm long, chopped carbon fibers in a polypropylene matrix were manufactured using the wetlay technique at fiber volume fractions (FVF) from 10% to 25%, and tests simulating the compression molding process were conducted. The packing stress of the CMT followed a power law relation with FVF. A single fiber pull-out fixture was used to measure the ...

When operating a cellular radio system at nearly full capac-ity, admitting yet another user may jeopardize the stability of the system as well as the performance of the individual users. Therefore, proper admission control is crucial. Prior art includes algorithms which are lim-iting the number of users or the uplink interference per cell. Both are known to yield roughly the same performance, b...

Glucoamylase was covalently immobilized through the spacer-arm of the poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) spheres by using a glutaraldehyde as a coupling agent. The influence of the enzyme load, applied to the support on immobilization, yield and specific activity, has been determined. Obtained specific activity was 700 U/g with immobilization yield of 35 %. The Km val...

Using a multiplexed LNA-based Taqman assay, RT-digital PCR (RT-dPCR) was performed in a prefabricated microfluidic device that monitored absolute viral load in native and immortalized cell lines, overall precision of detection, and the absolute detection limit of an occult RNA virus GB Virus Type C (GBV-C). RT-dPCR had on average a 10% lower overall coefficient of variation (CV, a measurement o...
