Biomonitoring of aquatic habitat using Apodu Dam in Malete, Moro local government area of Kwara state Nigeria as a case study
No full textWater bodies such as dams are an essential part of the ecosystems and the Apodu dam, a Local Government Area of Kwara State supplies water for the populace of Malete. The water is used for both domestic and agricultural purposes. Given the proposed rural development in the catchment area of the Apodu dam, it becomes imperative therefore to do extensive biomonitoring of the dam before the development begins so as to determine the likely source of pollution in the dam as well as determine the health of the dam. Ten samples of both water and plants were collected at different sampling points designated as A-J. The samples collected were digested and analyzed using standard techniques. Data generated from the research were subjected to T-test to determine whether there is a significant variation in the two sets of data. The parameters examined fall within the permissible level of standards set by the Federal Environmental Protection Agency (FEPA) and the World Health Organisation (WHO). Total hardness (TH) was 88.00-128.80 mg/l, pH 6.60-6.80, Total dissolved solids (TDSS) 242.00-420.00 mg/l, Electrical conductivity 102.32-103.39 µs cm, Biological Oxygen Demand (BOD) 3.47-3.53 mg/l, Chemical Oxygen Demand (COD) 104.00-168.00 mg/l and Dissolved oxygen (DO) 3.47- 3.53 mg/l. The lower concentration of DO is an indication of high water quality and this is advantageous for aquatic life as it suggests that there is less decomposition of foreign materials. In conclusion, high potential for an increasingly detrimental impact on the water quality resulting from increased anthropogenic activities especially if the proposed developments commence is imminent. </p

No full textEconomic impact is a stimulating effect on the economic condition of various regions. The paper describes the influence of the structure of the object on the choice of recreational activities, taking into account the sensitivity of the mountain structure to anthropogenic impact.Determined the value of the initial values of the applications of sociological research, which used to calculate the natural-territorial complexes - these are water bodies located on the territory with identified orographic structures, surrounded by forests, taking into account possible options for recreation.Evaluated of the assessment and comfort of the recreational area, based on the identification of psychophysiological characteristics, such as the sensation of noise, thermal effects of the environment. The development of recreation centers associated with the demand for recreationists, which also determined by the level of development and material base.Studies on the study of the Issyk-Kul region that the geographical characteristics of the territory (relief, water bodies, climate, etc.) have not only attractiveness, but inhibitory factors for rare types of recreational activities. </p
Duodenal injury: A challenging diagnostic enigma for clinicians
No full textThe objective of the article is to familiarize clinicians with duodenal injury and to recognize timely intervention to prevent morbidity and mortality associated with such injury. Although uncommon, duodenal injury challenges a clinician’s ability to diagnose and treat it in a timely fashion to prevent any associated mortality. The retroperitoneal anatomy makes duodenal injury difficult to diagnose. However, a high degree of suspicion based on the mechanism of injury and appropriate, timely diagnostic study leads to the correct identification of injury to the duodenum. The specific treatment depends on the type of injury that is detected. In conclusion, early recognition, and timely intervention of duodenal injury leads to a successful outcome. </p
Perrotta Hypersexuality Questionnaire (PeHy-Q): Development, regulation and validation of a new psychometric instrument for the diagnosis of hypersexuality
No full textIntroduction: The clinically relevant condition of hypersexuality is to date nebulous in its definition, and although it is understood as a psychological and behavioural alteration as a result of which sexually motivated stimuli are inappropriately sought and often experienced in a way that is not entirely satisfactory, it is unclear whether it is an obsessive disorder or is a trait of a more complex personality disorder or a consequence arising from a medical condition, whether primary or secondary. Methods: Using the Perrotta Hypersexuality Global Spectrum of Gradation (PH-GSS) as a model, the clinical and control population was selected to validate a new psychometric test, then compared with the Sexual Addiction Screening Test (SAST-R, v. 2.0). Results: Statistical analysis showed that the new psychometric test has a well-defined and stable construct (R = 0.975; p = 0.000), the variables are well represented (R = 0.999; p = 0.000) and it is positively correlated with the other constructs already validated (R = 0.951; p = 0.000). Conclusions: Perrotta Hypersexuality Questionnaire (PeHy-Q) is a valid, efficient, and effective psychometric tool to diagnose the clinically relevant condition of hypersexuality to improve the structural and functional framing of the patient and the appropriate therapy to pursue.</p
Deciphering PPAR-inducing pathway clarifying the link between Alzheimer’s Disease and diabetes
No full textDiabetes is a widely prevalent metabolic disorder characterized by chronic hyperglycemia. This condition is caused by various factors that ultimately result in pancreatic β cell failure. The American Diabetes Association (ADA) recognizes two main types of diabetes: Type 1 diabetes mellitus (T1DM) and Type 2 diabetes mellitus (T2DM) [1-4].</p
Fractal space-time and variations of the hubble constant
No full textSpatial variations of the Hubble constant are considered according to Riess, et al. (2018). It is noted that the values of the Hubble constant form an almost fractal manifold. This fact suggests that the variations may be associated with local gravitational perturbations in the neighborhoods of galaxies, in which there are Cepheids and supernovae selected for measurement. The aim and purpose of the study is to show that the spatial variations of the Hubble constant may be due to the fact that the galaxies belong to outskirts of the Local Supercluster.</p
Negative entropy production in L-lactate dehydrogenase kinetics
No full textFröhlich theory of coherent excitations in biological systems is analyzed. L-lactate dehydrogenase kinetics is studied using the activation process model for non-equilibrium cases. The model explains the process of energy accumulation necessary for carrying out catalytic reactions in a living cell by means of interaction of quantum subsystems with thermal equilibrium radiation, light, and radiation energy of metabolic processes occurring in the cell. It is shown that lactate dehydrogenase catalyzes the interconversion of pyruvate and lactate with concomitant interconversion of NADH and NAD+ in three ways, that is, three reactions occur simultaneously. Negative information entropy for the reactions under consideration is calculated. Its absolute value is equal to that of information entropy of the elementary activation act. This fact ensures the principle of stable non-equilibrium and indicates the reaction under consideration belongs to a living cell.</p

Smallholder farmers’ perception on climate change, information needs and adaptation strategies for improved pineapple (Ananas comosus) production in Awaé Cameroon
No full textThis study examined smallholder pineapple farmers’ experiences of climate variability and change in production, as well as ranked adaptation and information source options using data from primary sources. The primary data consisted of a survey on pineapple growing in Awaé. The analysis revealed that pineapple farmers experience climate variability and change evidenced mainly through irregular rainfall patterns (100%), excessive heat (97.14%), drying of streams (85.71%), and rising temperatures (77.14%). These variabilities cause a change in color and taste (40.00 and 45.71% respectively), a reduction in fruit size and yield (68.57 and 100% respectively), and consequently, a reduction in income from pineapple production. Farmers identify deforestation (54.29 ± 0.51%), bush fires (34.29 ± 0.48%) as the major causes of climate change. Although the use of soil conservation practices (e.g. mixed and rotational cropping), bush fallow and crop diversification emerged as the three main adaptation options employed by smallholder pineapple farmers, climate change has the potential to reduce pineapple production in Awaé. Therefore there is a need for future studies to identify adaptation measures that will help improve pineapple production in the area. These farmers are willing to receive information commencement of rain, the prediction of stopping rain, the impact, adaptation strategies, and mitigation strategies to climate change. They can be informed through phone text messages, television, radio, and even demonstration methods for them to effectively follow up on climate change to better improve their pineapple production in Awaé.</p
Forest restoration, resources sustainable use and high-quality sustainable management
No full textAs the economy develops and the population increases, there is an increasing demand for goods such as timber, food, medicine, and so on, and ecological services such as fresh water and the environment. Because goods and services produced by the original forest cannot meet the increasing need of people, so most of the original forest has become farmland, plantation, and grass. In the process of Forest restoration, a lot of exotic plants was introduced to produce special products and service. As exotic plants grow, vegetation declines, and crop failure will happen in dry years or resource waste in wet years. In order to solve these problems, Years of theoretical research and investigation in fixed positions have shown that there is a soil water resources use limit by plants and the soil water vegetation carrying capacity in the process of vegetation restoration. When the soil water resources in the range of the maximum infiltration depth are equal to the soil water resources use limit by plants, the plant water relation enters the key period of plant water relation regulation. If existing plant density is more than the soil water vegetation carrying capacity in the key period of plant water relation regulation, the plant water relation has to be regulated on the soil water vegetation carrying capacity to get maximal yield and service and realize high-quality sustainable management of forest vegetation in a water shortage area.</p
