Liquid-liquid equilibrium data for aqueous biphasic system formed by polyethylene glycol (PEG)/sodium citrate (C6H5O7Na3)/water (H2O) were determined at 298.15 K, respectively. Binodal data were correlated using a four- parameter equation. The effect of the molecular weight of PEG (1500, 3000, 6000) on the binodal curves was investigated, and it was found that the two-phase region expands with an increase in the molecular weight of PEG. The effects of some monohydric (methanol, ethanol, propanol...

Background: In an economic sense, derivatives are often used for commodities, including oil, gasoline, silver, gold, iron ore, currencies, stocks, and bonds. The derivative is considered as a financial contract that derives its value from an underlying asset. The buyer of the asset agrees to purchase it on a specific date and at a particular price. In the past couple of decades, financial derivatives evolved, and this is not unrelated to the fundamental changes in the financial markets across th...

Purpose: Mounting evidence supports the implementation of neuromuscular training (NMT) interventions to improve biomechanical profiles for prevention of musculoskeletal injury in dynamic pivoting athletes. Research has demonstrated there is a clear link between functional movement behavior and vulnerability to injury. However, there is limited research examining the capacity of NMT to positively influence pathomechanical movement behavior. This investigation assessed the strength, balance, and f...

There is mutual acceptance between the Senoufo and Malinké, two ethnolinguistic groups of Côte d’Ivoire. In order to assess language as the mediating factor between the two groups, two different questionnaires have been submitted respectively to some individuals of each group. The statistical analysis and interpretation of the data have permitted to reveal that the Dyula language plays a key role in the peaceful relations between the Senoufo and Malinke of Côte d’Ivoire. It has been ...

Venture capital, as an active financing method, has introduced many non- capitalized services while providing funds. Green technological innovation, as an important force in promoting the green and ecologicalization of China’s industrial structure, has an impact on the relationship between the two analyses is necessary. This paper explores the relationship between green technology innovation and venture capital through panel data from various regions of China (except Hong Kong, Macao, Taiwan and...

The loss of crop production caused by weeds has become a serious threat to many important crops. The utilization of microorganism metabolites is considered as an effective method towards a wide variety of weeds in the field. In this study, sixty-eight strains were isolated from weed plants with infections symptom. Each strain was cultured in submerged liquid medium. Culture filtrate was obtained from fermented broth by filtration and it was used to determine herbicidal activity both in vitro and...

This paper introduces the working principle of CPK (Combined Public Key) and the general method of constructing identifier-based public key, which can not only solve the problem of key distribution, but also solve the authentication problem of identifier claimed by the subject. As basic functions, identifier authentication, identifier password, digital signature and key encryption are introduced. Where Identifier authentication is a new concept, and a separate authentication protocol is formulat...

Douala, situated between latitude 4.00 - 4.15 and longitude 9.65 - 9.95, is the economic capital of Cameroon in the Littoral Region and it hosts more than 80% of the industries in the Country. Increased urbanization and agricultural activities have a potential for trace metal contamination as such, the trace metal evaluation of groundwater in Douala begs our attention. This study investigated the trace metal content of groundwater sources; determined estimates of the health hazard and pollution ...

In many geographic areas influenced by tropical and temperate climates, natural forest ecosystems have been destroyed in favour of plantations of allochthonous trees which are economically profitable for different aspects of the timber industry. Some of these mature plantations degrade the soils and inhibit natural regeneration of the local flora; others, due to the physical constraints they impose, can contribute to the installation and the development of autochthonous taxa. The plantations of ...
