Measuring the Use of Mobile Applications in Higher Education

The proliferation of use of mobile applications has increased access to information and the way we communicate and collaborate. Higher education institutions must follow this trend and cannot ignore this. They should make efforts to integrate them in their routines, namely in their students. This chapter aims to extend the understanding about the actual use of mobile applications and how users report using them, namely in the classrooms. The main objective of this literature review is to conduct a critical literature review on this use. For this purpose, an analysis of several articles in reference publishers and journals was carried out. As a result of the analysis and cross-checking of literature data, it could be concluded that the use of mobile applications that users make and the one they claim to make may differ. It is intended to understand this problematic and analyse methods that may result in more precise data in this context. These data may be used, for example, to define strategies, namely helping higher institutions defining the use of m-learning.

PROBABILITY DISTRIBUTION OF TIME DURATION OF MANUAL OPERATION IN THE PRODUCTION OF GLASS EYES

When precise planning of capacities and times of production is needed, there must be precise data for calculation. Not all operations have to have a normal time duration distribution. Counting with average values or use values from guessed distribution can lead to mistakes in actual production planning. This article aims to determine time probability distributions to manual operations. Tests of goodness of fit are used to search for more suitable distributions. This approach is presented in a case study of glass eyes manufacturing. Results show that there can be differences between the estimated normal distribution and another more suitable one. By using tests of goodness of fit to define the correct distribution, more precise production and capacity planning results can be achieved.

Lineal Megalithic Rock Scripts as precursors of Iberian and other lineal Mediterranean/Euro African ancient writings: the case of Fuerteventura (Canary Islands, Spain)

Lineal Megalithic/Paleolithic Lineal signs/lines may have a variety of purposes or representations. Some authors have proposed they represent sky, planets and stars and their movements, space/time representations or others, including letters/syllables or symbols/events. Some are painted, other incised; the latter are relatively more common in Megalithic scripts. Man is “writing” or creating handmade figures on stones /rocks and other supports, which sometimes have intentionally been polished since Paleolithic times: at least 70,000 years BP (Blombos Cave, South Africa). Megalithic script is named because it is associated to megalithic structures, although not exclusively. Von Petzinger 40,000 years old “symbols” and/or writing are extended worldwide in Paleolithic caves and other rocks. Man connection was worldwide in Paleolithic times. Canary Islands incise or picketed lineal writing exists with a transcribed and translated meaning collection of signs (Ibero-Guanche or Latin inscriptions and Lybic ones). Also, other African/European/Mediterranean lineal scripts there exist and examples are given in the present paper. Fuerteventura Island contains in addition many small or bigger stones and rocks with these Paleolithic/Megalithic incised lines all over its territory. About timing in which these stones that were incised by man, we are only referring to a kind of stone crafting. However, we do not discard that they were made by man several thousand years BP. Some Paleolithic/Megalithic scripts are mixed with clear Iberian semi-syllabary signs in Fuerteventura and other Canary Islands. They may reflect the evolution of more ancient Megalithic scripts to lineal writings like those detailed in the present paper and others. Finally, writing concept should be redefined whenever more precise data and dating be available.

The Impact of the Pandemic on Economic Crime

This paper aims to outline possible directions of criminal activity that are part of both state and global economic crime. It is not a novelty that periods of economic crises carry particular criminogenic potential, affecting the scale and dynamics of specific crime categories. The ongoing pandemic makes precise data collection or statistical calculations, in the context of the problems described in this paper, difficult. Nevertheless, at this stage, it is possible to indicate certain areas which, from the perspective of criminal law, should be of interest for criminal law specialists, but also criminologists aiming to develop tools to combat the most serious pathologies in business trading.

Monitoring Land Change of Cover in Al-Rusafa District In Baghdad City by using Remote Sensing and GIS Techniques

Change detection of land surface is critical to execute precise data about territory of study for any sorts of arranging improvement. Technologies of Remote Sensing and GIS and have accomplished incredible strides to tackle the investigation issues like changes of land cover. The point of that study is to deliver guides of land front of Al-Rusafa District on year 2000, 2018 to screen the potential the expectable changes especially in vegetation land and metropolitan or built land, furthermore, identify the cycle of city settlement. Two multi-transient satellite picture information, Upgraded Topical Mapper picture information from 2000 and OLI Satellite picture information from 2018 were utilized in that task. That study direction is the major approach of classification approach to supply divided maps, and cover of land categories were recognized and map. Spectral indices (NDVI, NDBI, NDWI) utilized to identify the changes of expanding and diminishing land the change detection in (Arc Map 10.5 ) Envision was utilized to identify the urban development and the concentrated alters encompassing the urban regions. Cellular automata of Markov was utilized to mimic the patterns of land utilize and change of cover the period of 2000 to 2018 cross-tabulation lattices between diverse stages were delivered to interpret the patterns of change of covers from one cover land to another, these measurement information straight forwardly regions communicated the alter of land cover. The results about appear these demonstrate that around (31.8 %) of Change from one Kind of land cover to another one though around (68.2 %) of the region Remained unaltered between (2000, and 2018)..

Geological and tectonic preconditions for hydraulic heterogeneity of the rocks in the area of the Gotse Delchev valley

Hydrogeological conditions largely depend on the permeability of the geological environment. In areas with complex geological and tectonic conditions, the detection of hydraulic heterogeneity of the rocks and determination of groundwater-rich zones is a challenge for hydrogeological practice. The aim of the study is to analyze the geological and tectonic prerequisites for hydraulic heterogeneity of the sediments for the Gotse Delchev valley (Southwestern Bulgaria), which predetermine the degree of their water productivity. In order to obtain more precise data for specific sites, a geophysical survey was conducted. The Self-Potential method was chosen, which is one of the most commonly used techniques for applications for hydrogeological purposes. The results of the geophysical survey carried out in selected sites allowed to locate groundwater-rich zones, to establish the depth of occurrence of hard low permeable rocks, as well as to confirm the presence of faults.

Checklist of the Pipunculidae (Diptera) of mainland France: further faunistic records and description of a new species

Since the first faunistic study of the Pipunculidae (Diptera) of mainland France in 2006, new material from 37 natural sites and four private collections has been evaluated by the authors of this article. A total of 5739 specimens of Pipunculidae collected in France were examined, of which 5214 were identified to species by the authors, for a total of 114 species. DNA analyses were also carried out on some specimens to confirm their morphological identifications. The list of Pipunculidae recorded in mainland France is updated to include 140 species. Tomosvaryella estebani sp. nov. is described from material collected in France and Italy. Twenty-four species are also reported for the first time from France. The records of Cephalops (Semicephalops) carinatus (Verrall, 1901), Cephalosphaera (Cephalosphaera) furcata (Egger, 1860), Eudorylas terminalis (Thomson, 1870) and Jassidophaga villosa (Roser, 1840), without precise data in the literature, are now precisely located in France with this work. For the other species, we provide new post-2006 records.

SECOND STAGE OF PEASANT EXILE TO THE NORTH OF WESTERN SIBERIA (1931): LITTLE-STUDIED AND DEBATABLE ISSUES

Researchers identify three stages in the organization of forced migrations of peasants and their families in the early 1930 to the North of Western Siberia. This was due to mass dekulakization in the USSR. Previous studies often contain contradictory and incomplete data. These relate to the chronology stages and number of peasants. The article is a continuation of the research topic. This is a clarification of the stages of the “kulak” exile and the number of peasants sent to the North. This is the territory of the Khanty-Mansiysk and Yamalo-Nenets Autonomous districts today. In the study of the beginning of the stage (1930), we have clarity. We do not have complete data about the second stage. These are questions such as the time of sending special settlers, transportation, the number of exiles. We want to clarify which organizations they were sent to work for. We do not have precise data on the geography of settlement. We do not know the total number of special settlers by the end of 1931 in the national districts. The researchers did not provide data on demographic losses. The article examines the little-studied and debatable issues of the second stage of peasant exile based on available research and available sources. It is considered on the materials of the Ostyako-Vogul and Yamalo-Nenets districts (1931). The author finds out the chronological boundaries of the methods of transporting peasants in the summer of 1931. The article provides reasonable data on the number of sent special settlers (1930-1931). The researcher shows the placement areas. The article examines the actual presence of a special population in the national districts by the end of 1931.

Semen extenders: An evaluative overview of preservative mechanisms of semen and semen extenders

Reproduction is fundamental for all living things as it ensures the continued existence of a species and an improved economy in animal husbandry. Reproduction has developed since history, and diverse processes, such as artificial insemination and in vitro fertilization, have been developed. Semen extenders were discovered and developed to protect sperm from harmful factors, such as freeze and osmotic shock, oxidative stress, and cell injury by ice crystals. Semen extenders preserve sperm by stabilizing its properties, including sperm morphology, motility, and viability and membrane, acrosomal, and DNA integrity. Therefore, semen extenders must provide a favorable pH, adenosine triphosphate, anti-cooling and anti-freeze shock, and antioxidant activity to improve semen quality for fertilization. Hence, this review provides precise data on different semen extenders, preservative mechanisms, and essential additives for semen extenders in different animals.
