although the internet has become one of the most important information resources for university students, excessive internet use can be defined as uncontrolled and harmful use of the internet, in other words, internet addiction. internet addiction (ia) can be described as a maladaptive preoccupation with internet use impairing social, occupational and other areas of a person’s functioning. rece...

The direct conversion reaction of glucose to 5-hydroxymethylfurfural (HMF) is studied using metal organic framework (MOF) as Lewis-acid catalysts and a polyoxometalate (POM), silicotungstic acid, Brønsted-type acid with mixture 1% solution in ?-valerolactone (GVL)-10% H2O at 140 °C. study carried out two routes: one MOF POM tandem added independently the other through synthesis composite materi...

A 16-week feeding trial, involving 18 weaner pigs in a randomized complete block design, was carried out to determine the value of poultry offal meal (POM) as protein supplement for grower at three dietary levels, 0%, 10% and 20%. Liveweight gain, dressing percentage backfat thickness were significantly (<0.05) higher fed 20% POM level. The cut parts, heart, liver kidney, also increased with...

Sinking of gelatinous zooplankton biomass is an important component of the biological pump removing carbon from the upper ocean. The export efficiency, e.g., how much biomass reaches the ocean interior sequestering carbon, is poorly known because of the absence of reliable sinking speed data. We measured sinking rates of gelatinous particulate organic matter (jelly-POM) from different species o...

A novel route to facilitate the degradation of phenol is reported. This new approach is based on a micellar polyoxometalate (POM) catalytic system. The micellar POM catalyst could promote phenol molecules' degradation into a simple inorganic compound such as CO2 using only air as an oxidant under room conditions. The results of the recycling experiment suggests that the micellar POMs may be use...

Production systems design is critical to achieving manufacturing performance and objectives. Although generic approaches to this design are available they may not be able to objectively address specific manufacturing configurations. Here it is argued that product oriented manufacturing (POM) organization offers advantages in relation to the function oriented one. Based on this, a methodology sp...

Ten organoimido polyoxometalate (POM)-based chromophores have been synthesized and studied by hyper-Rayleigh scattering (HRS), Stark and Resonance Raman spectroscopies, and density functional theory (DFT) calculations. HRS β0 values for chromophores with resonance electron donors are significant (up to 139 × 10-30 esu, ∼5 times greater than that of the DAS+ cation), but systems with no donor, o...
