Peruvian Union University is a Seventh-day Adventist university in Lima, Peru. It is the second largest of ten Adventist universities in South America. Its acronym is "UPeU". Founded in 1919 as Instituto Industrial in Miraflores, Lima, it was the first higher education facility started by Seventh-day Adventists in Peru. Wikipedia.

Two mysticete fossil whales from the upper Miocene of the Pisco Formation in Peru are described that show healed bone-fractures in ribs. One specimen is preserved in a tuffaceous, diatomaceous siltstone and the other specimen is preserved in siltstone. Both specimens are well preserved, mostly articulated and almost complete. Shark teeth were found associated with one of the skeletons, but both specimens lack any trace evidence for the activity of macro-scavengers. We suggest that the cause of bone fracture may have been collision with rocky shores, other whales, or large predators. The fact that the rib fractures healed indicates that the whales did not die due to the bone fractures. Sedimentologic and paleontological evidence indicate that they were rapidly buried in the marine platform with well-oxygenated water. © 2015, Sociedad Española de Paleontolog a.

The Pisco Formation in Peru contains abundant fossil cetaceans in middle Miocene to lower Pliocene sandstone, siltstone, and tuffaceous and diatomaceous mudstone. Fossil whales are especially abundant in the uppermost diatomaceous units. Most specimens are well articulated or partially disarticulated but associated. Degree of preservation is exceptionally high and uniform among articulated and disarticulated specimens and on the lower and upper surfaces of the bones. Some specimens have baleen preserved in anatomical position. Bones show no evidence of bioerosion by macro- or micro-invertebrates, except for a very limited amount of microbial borings. Diatomaceous layers seem to lack bioturbation. However, bioturbation did occur in a few tuffaceous silty and sandy layers of the lower part of the formation. Shark teeth are found associated with many of the specimens; however, despite abundance of whale skeletons, shark tooth marks are extremely rare. Several lines of evidence indicate that sediments and whales were deposited in a shallow-to-deep shelf environment (an embayment), and not in a beach environment. The thick diatomaceous successions record conditions of strong ocean upwelling indicated by the abundant occurrence of the diatom species Thalassionema nitzschioides. The exceptional preservation of diatom frustules suggests that they reached the seafloor very rapidly and were not successively reworked. The hundreds of whale specimens found, their excellent preservation, and their high degree of articulation make the Pisco Formation fossil whales the best representative assemblage of fossil Mysticeti known so far. The abundance of whale skeletons and other vertebrates in the diatomaceous beds, their excellent preservation, including evidence that soft tissue (baleen) was still present at burial, and the degree of articulation, point to frequent mortalities followed by rapid sedimentation that prevented decay of the skeletons and colonization by invertebrates. Sedimentation rates appear much higher than rates inferred from some other modern and ancient settings where whale skeletons have been found. © 2014 Elsevier B.V.

The purpose of this study is the construction and evaluation of the psychometric properties of an instrument that is capable of detecting the risk of addiction to social networks in adolescents between the ages of 14 and 18. For this reason, a conceptual definition of the construct was performed on the first stage of the study and a preliminary instrument (59 items) was developed based on the literature on addiction to new technologies. On the second stage, a pilot sample of 205 school students was considered. An exploratory factor analysis was performed in order to make a rigorous analysis of the theoretical and dimensional nature of the construct. On the third stage, the psychometric properties of the scale were verified along with 453 high school students ranging from third to fifth high school grades belonging to 7 high schools in the city of Lima Metropolitana, where the confirmatory factor analysis showed that the factor structure is good (RMSEA =.047, CFI =.91) and Cronbach's alpha coefficient were between.71 and.96 for both the dimensions and the global scale. The scale finally consisted of 43 items assessing 7 dimensions of addiction to social networks: loss of control, abstinence syndrome, decreased academic performance, mood modification, dependency, loss of interest in other activities and conflicts in the social sphere. We conclude that the instrument gives evidence of good internal consistency and construct validity. © 2015 Elsevier Ltd. All rights reserved.

Microencapsulation of flax oil was investigated using zein as the coating material. Central Composite Design - Face Centered was used to optimize the microencapsulation with respect to zein concentration (x1) and flax oil concentration (x2) using spray drying. Also, freeze drying was carried out at two zein:oil ratios. The quality of microcapsules was evaluated by determining encapsulation efficiency, flowing properties (Hausner ratio), and evaluating the morphology with scanning electron microscopy. The response surface model for microencapsulation efficiency showed a high coefficient of determination (R2 = 0.992) and a non-significant lack of fit (p = 0.256). The maximum microencapsulation efficiencies were 93.26 ± 0.95 and 59.63 ± 0.36% for spray drying and freeze drying, respectively. However, microcapsules prepared by spray and freeze drying had very poor handling properties based on the Hausner ratio. The bulk density decreased with an increase in zein concentration at the same flax oil concentration. The morphology of the flax oil microcapsules depended on the zein:flax oil ratio and the process used for microencapsulation. Flax oil microcapsules prepared by spray drying appeared to be composed of heterogeneous spheres of various sizes at high zein:flax oil ratios. Microcapsules prepared by freeze drying resulted in agglomerated small spheres. These microcapsules might find a niche as functional food ingredients. © 2011 Elsevier Ltd.
