Using a well calibrated sodium iodide (NaI) detector. The activity concentrations of 40K, 234U, and 232Th in crops and soils of the selected fertilized farmers of Rivers State have been determined. The activity concentration of radionuclides of 40K, 234U, and 232Th were all higher than its respective control values, which show that the fertilized farms contain more radionuclide than the unfertilized farms(control) and this may be due to the long use of inorganic fertilizers during cultivation on the selected Agricultural Development programme farms (Fertilized Farms). This variation may be due to differences in organic matter, soil content and type of soil of the selected farms. The mean transfer factor obtained is of the order 234U < 232TH < 40K which shows that activity concentration of natural radio isotopes within the study area are high and also the rate at which the radionuclides are transfer from soil to crops is also high. The result obtained show that there is high transfer ratio of radionuclide from soil to crops of the selected fertilized farms and this requires that the uses of NPK fertilizers should be under radiological control for consumption safety.","PeriodicalId":124795,"journal":{"name":"Physical Science International Journal","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124432002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The provision of bioclimatic habitats to households is therefore necessary since it will contribute to the reduction of energy consumption. This work consists in making a study of the thermal behavior of a habitat designed with foamed concrete (FC) in order to evaluate its thermal performance for the improvement of its thermal comfort and to compare its average internal temperature with those of other materials. \u0000Study Design: A calculation model developed under the COMSOL Multiphysics 5.3a software was used to simulate the thermal behavior of a foamed concrete habitat. The meteorological data used are those of Ouagadougou in the month of April (hottest month in Burkina Faso) on April 15, 2019 (with April 15, the hottest day of the year 2019) \u0000Methodology: The temperatures of each side of the walls were determined. Moreover, the study of the influence of the thickness of the walls on the average internal temperature made it possible to determine an optimal thickness. Then, the thermal phase shift, the thermal amplitude reduction and the damping factor were carried out. \u0000Results: The results obtained in the weather conditions of April in Ouagadougou, lead to an average internal temperature of the building of about 304 K, for a wall thickness of 17.5 cm. There is a thermal phase shift of 8 hours, and a reduction in thermal amplitude of 9°C or a damping factor of 8.6%. The maximum average internal temperature of the foamed concrete was compared with those of the cement block, the CEB, the adobe, the CLB which present respectively 311 K; 309.2K; 309K; 308.5K. \u0000Conclusion: A building constructed with foamed concrete has a low average internal temperature compared to cinderblock, CEB, adobe and CLB. Thus, this material makes it possible to provide more thermal comfort and can be used for the construction of habitats with good energy efficiency.","PeriodicalId":124795,"journal":{"name":"Physical Science International Journal","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126036693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used International Reference Ionosphere (IRI-2016) to collect data from five (5) quiet days of each characteristic month of each season. This study reveals that in this station located at the ionospheric equator, the variability of foE follows the evolution of the sun intensity during the day. There is a correlation between foE and the solar cycle phase, the season, and the time of day. During the day [0500 LT-1900LT], the foE profile does not show a winter anomaly, contrary to what is observed in the F2 layer  at the minimum and maximum  SC21 and SC22. On the other hand, a nocturnal winter anomaly was observed related to that observed in the F2 layer in the same periods. The study of foE at the Ouagadougou station will allow ionospheric physicists to have visibility on the seasonal variability of foE in this station.","PeriodicalId":124795,"journal":{"name":"Physical Science International Journal","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116794670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on a Lorenz-type chaotic model with multi-attractor coexistence, the Filippov system was established by introducing non-smooth terms as well as an external excitation. With multiple stable attractors in the discontinuous vector field, the parameter changes have led to complex transition patterns between the attractors and the non-smooth interface, or between the attractors. When an order gap exists between the exciting frequency and the natural frequency, implying the mixed-mode oscillations. Here we have taken several excitation amplitudes to cover different coexistence regions, a set of mixed mode oscillation patterns were obtained. Besides, the bifurcation set of two generalized autonomous subsystems and the coexistence region of attractors were discussed. Combined with the transformed phase diagram method, the bifurcation mechanism of bursting oscillation and the sliding dynamical behaviors of the system at the discontinuous interface has revealed with slow varying parameters access in different regions of multistable attractors coexistence. The alternations between quiescent and spiking states become more frequent and complex, leading to the change of the structure of the bursting oscillation modes. Moreover, the non-smooth partition interface of the system yields multiple non-smooth bifurcations, which will also affect the oscillation modes of the generalized autonomous system.","PeriodicalId":124795,"journal":{"name":"Physical Science International Journal","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122688990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In black hole thermodynamics, black hole entropy is a measure of uncertainty or lack of information about the actual internal configuration of the system. The Bekenstein bound corresponds to the interpretation in terms of bits of information of a given physical system down to the quantum level. However, at present, it is not known which microstates are counted by the entropy of black holes. Here, i show that the new formulation of entropic information approach, based on the bit of information gives an explanation of information processes involved in calculating entropy on missing information from black holes as well as down to the quantum level. Moreover, this formulation of entropic information constitutes a new coherent global mathematical framework candidate to be the Grand Unification Theory; with information as the ultimate building block of universe.","PeriodicalId":124795,"journal":{"name":"Physical Science International Journal","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122089469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It provides a few examples that show the effectiveness of this approach and demonstrate inconsistent points of some mainstream physical ideas. Furthermore, other well-established physical principles can be utilized for this end. Unfortunately, a scientific work that undertakes this assignment can hardly be found in the current mainstream literature. Several cases are discussed in detail. The results show inconsistencies of fundamental standard model theories, such as quantum chromodynamics and the electroweak theory.

Complex spin and angular momenta interactions of the cations, anions, protons and halides are considered.  A novel method of using the static magnetic field, static electric fields, radio frequency waves and ultrasounds for selective precipitations of LiOH (s) with retarding Li2CO3 (s) is presented. The ultrasounds and radio waves may agitate in operation to prevent clogging of the graphene/nanodiamond nanofiltration membrane. On the basis of separation factors (ξ) as by ratios of various NMMs of the cations in geothermal salar brines, the separation factor varies from: ξ(Li+/Na+) = 1.45; to ξ(Li+/K+) = 8.35 to ξ(Co/Li) = 0.607 to ξ(Co/Mn) = 0.635. The similar, large NMMs of Li with Co and Mn with small differences in spins may by the theory here be the explanation and cause for more difficult separation of Li from Co and Mn and the current empirical affinity of Li for Co and Mn as indeed Co and Mn have been observed as sorbents for Li.","PeriodicalId":124795,"journal":{"name":"Physical Science International Journal","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114990919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
