A sample of ethanolic extracts of the husk of Theobroma cacao L. was scru-tinized using a UHPLC/DAD/MS Thermo scientific Dionex Ultimate 3000 RS coupled to a Thermo scientific LTQ XL mass spectrometer. In addition, about seven different chemical compounds were tentatively identified in this species based on chromatography retention time (Rt), UV and MS/MS spectra and compared with those of iso ...

The work shows that the associated Einstein-like gravity for the Klein-Gordon field shows the spontaneous emergence of the “cosmological” pressure tensor density (CPTD) that in the classical limit leads to the cosmological constant (CC). Even if the classical cosmological constant is set to zero, the model shows, that exists a residual theory-derived quantum CPTD. The work shows that the cosmological constant can be considered as ...

Quality represents the first competitive advantage of industrial and service companies. The race by companies to provide a high-quality output, in fact, derives from the intensity of competition, leading to continuous quality improvement, because it is impossible to compete in the local and global markets without providing high-quality products to be accepted by cus-tomers; thus quality becomes the primary goal to be met with atte ...

Thrombotic complications accompany surgical treatment, especially in children. Thrombosis is one of the actual problems of pediatrics. This problem is associated with severe complications, serious health problems in infant. This can contribute to increases of mortality in children with congenital heart diseases (CHD). In this article we discuss some aspects of thrombosis in the postoperative period of CHD in children w ...

In a two-echelon “Farmer-Supermarket Direct-Purchase” supply chain composed of a supermarket and a farmer, the dominant supermarket used the Nash equilibrium solution and the Shapley value as the fair reference points. By constructing the Stackelberg game model, this paper analyzed the influence of supermarket’s fairness preference on the operation of supply chains and made a sensitivity analysis. The research indicates that super ...

Periodontal disease is one of the most common infectious diseases in pregnancy. The disease is caused by bacteria that produce inflammation of gingiva through production of inflammatory mediators that may have direct insult on amnion. Untreated and chronic dental infections have a possibility of causing harm to both the mother and the baby. This was an analytical cross-sectional study the purpose of which was to determine the prev ...

In this article we consider a mathematical model for the weak decay of muons in a uniform magnetic field according to the Fermi theory of weak interactions with V-A coupling. With this model we associate a Hamiltonian with cutoffs in an appropriate Fock space. No infrared regularization is assumed. The Hamiltonian is self-adjoint and has a unique ground state. We specify the essential spectrum ...

In an attempt to produce a reliable source of water, the water quality model—QUAL2Kw—was put to through calibration and validation tests. This model was implemented in the river Tungabhadra of India. This worked quite well for the project at hand but showed certain irregularities. Different Quality Management methods exist currently and for this project, their impact in DO concentrations were examined base ...

In this paper, a detailed water quality monitoring was conducted on desalination brine according to the basic health requirements for water quality in bathing beaches, swimming pools and other bathing venues. The results showed that desalination brine could fully meet the requirements, so its use as the water source of artificial “Dead Sea” was theoretically feasible. Through further analysis and research, a salt-oz ...
