One of the possible ways to further miniaturize technical devices is the utilization of the two-dimensional structures such as plates. The acoustic wave propagation is one of the important characteristics. This theoretical work provides two new shear-horizontal (SH) dispersive acoustic waves. The SH-wave dispersion relations are obtained in explicit forms for the case of the transversely isotropic (6 mm) plates. In the plate, the propagation of either new SH-wave is coupled with the electrical, magnetic, gravitational, and cogravitational potentials. Using the obtained SH-waves, it is possible to constitute various technical devices (filters, sensors, etc.) of acoustoelectronics and spintronics, and to integrate them in the new communication era based on some gravitational phenomena. Also, the plate SH-waves are apt for nondestructive testing and evaluation of (composite) thin films.

The geotechnical properties of soils for civil engineering constructions in Nyuene, Bonny Island were evaluated using seismic refraction survey. A 3-layer soil structure was delineated: topmost layer, 6.9 m thick; second layer, 17.1 m thick and consolidated bedrock layer extending to great depths. Results across these layers respectively reveal that Vp/Vs has averages of 1.29, 1.50 and 1.78 indicating fluid-saturated top layers; Poisson’s ratio has averages of -0.72, 0.05 and 0.29; Shear modulus has averages of 2.10 x108 Nm-2, 5.20 x108 Nm-2 and 8.09 x108 Nm-2; Young’s modulus has averages of 0.67 x108 Nm-2, 10.80 x108 Nm-2 and 20.80 x108 Nm-2; Bulk modulus has averages of 0.60 x108 Nm-2, 4.62 x108 Nm-2 and 16.7 x108 Nm-2. Furthermore, the ultimate bearing capacity averages at 464.5 kNm-2, 764.6 kNm-2 and 995.8 kNm-2 respectively across the layers and the allowable bearing pressure averages at 116.1 kNm-2, 191.2 kNm-2 and 248.9 kNm-2 respectively. The trend of the dynamic elastic parameters respectively indicates increase in compressive soil strength, increase in the capacity to withstand shear stress and increase in compaction. These values show that the consolidated layer can withstand more pressure and bear more load than the other layers. The properties of this layer fall within the standard criteria for civil engineering constructions. For the construction of high-rise buildings/skyscrapers and bridges in the study area, 24m of topsoil should be reinforced by piling. However, for other non-high-rise buildings/structures, about 7.0 m of topsoil should be excavated for proper siting of foundations due to the tidal flooding and land subsidence in Bonny Island and environs. This method should be combined with Cone Penetrometer Test at early stage of any construction work to properly determine the soil depth and geotechnical properties to locate foundations. This will forestall the problems of cracks in foundations and buildings collapse.

Tides created by the Moon on the Earth are discussed. A tidal wave slows down the rotation of the Earth. The Earth loses 3.3 TJ of kinetic energy every second. Almost all of this energy is converted to heat. However, a small part associated with the angular momentum is transmitted to the Moon. A formula for the efficiency of the transmitted energy is derived. It is proved that the efficiency is equal to the ratio of the following periods: day/month. The flow of energy from the Earth to the Moon is discussed. Its power and density are calculated: the power is equal to 100 GW and the density is equal to 1 mW/m2. The possibility that this energy is transmitted at the speed of light is discussed. It is shown that in this case the transferred angular momentum would be 17.5 million times less than the observed angular momentum. To reconcile the angular momentum transferred to the Moon with the equations of relativistic dynamics, the energy must be transmitted at a speed exceeding the speed of light by 17.5 million times. Therefore, the author puts forward the hypothesis that energy from the Earth to the Moon is transmitted instantaneously.

The present paper deals with the record of 76 species of birds from Bhambhor area which is in close proximity to the Wind Power Project Site in the Gharo (Coastal) Wind Corridor in Taluka Mirpur Sakro, district Thatta, Sindh. More than 11 types of habitats are available in the area supporting at least 10 Threatened/ Near-threatened species, mostly of waterbirds. Potential impacts on birds due to the operation of wind turbines have been mentioned which need to be mitigated during the construction and operational phase. At present, there are no serious threats to birds due to the developmental activities with regard to Wind Power Projects (WPPs) but as an immediate and necessary conservation initiative such as monitoring of bird populations visiting the area particularly in the migratory season is recommended on long term basis

In this study, Fish samples Clarias anguillaris, Synodontis budgetti, and Heterotis niloticus were collected during the rainy and dry season from Komadugu river basin, Yobe State, Nigeria for the determination of some heavy metals. The concentrations of heavy metals were determined using Perkin-Elmer Analyst 300 Atomic Absorption Spectroscopy (AAS) and X-Ray Fluoresces (XRF). The concentrations of all the heavy metals in the fish samples ranged from 1.18E+03 mg/kg. Heterotis niloticus were observed to show the highest total concentration of the heavy metals studied with a value of 2.19E+03 mg/kg, while Clarias anguillaris shows the lowest concentration with a value of 0.03 mg/kg. The accumulation of tissues of fish samples were observed to be in the order of gills>liver>intestine>flesh in both methods. The concentrations of all heavy metals were significantly higher using XRF method when compared with AAS. Fe shows the highest ADI value of 1.53E+00 mg/kg/day in Clarias anguillaris, while Synodontis budgetti shows the lowest value of ADI value of 8.23E-01 mg/kg/day among all the four species of fish samples studied. From the results obtained, the HQ values of some of the heavy metals in the fish samples during the rainy season were all above one (1), with the exception of HQ values during the dry season which was lower than 1. The lowest HQ value of 9.00E- 08 in all the fish samples study was lower than 1, while the highest HQ of 1.50E+01 As detected in all the fish samples was higher than the HQ values of one (1). Cancer risks were computed as 5.10E-02 for highest and 5.40E-07 for lowest chances for the study fish respectively. These risk values indicate that consumption of fish from the study area would result in an excess of 5 cancer cases per 1,000,000 people

The checklists covers vertebrate classes including Amphibia (Amphibians), Reptilia (Reptiles), Aves (Birds) and Mammalia (Mammals) recorded from the Nara Game Reserve area. Based on field surveys and review of literature, as many as two species of amphibian, 20 reptilian species, 129 species of birds and 21 mammalian species were recorded. A total of 75 floral species have also been recorded from the study area. We determined the present status of the vertebrate fauna of Nara Game Reserve area. Threats to the wildlife were also identified

The article reviews the well-known theories and ideas about the origin of life on Earth. We propose to divide all such theories into two classes. The first include theories and hypotheses that pretend to explain the phenomenal complexity of living beings and their radical difference from inanimate nature. The second class includes theories that do not explain the phenomenal complexity of living beings. One of the unusual and complex phenomena of the subatomic world called the quantum nonlocality is analyzed. The possible influence of this phenomenon on the synthesis of the first organic substances, and subsequently of living organisms, is investigated. The hypothesis of the quantum origin of life is considered, in which the concept of a united quantum state of a living system permeated with nonlocal connections plays the main role. It is shown that this hypothesis belongs to the first class, since it explains the phenomenal complexity of living beings and their radical difference from inanimate nature.

It points to the costly experiments on the detection of gravitational radiation, which have not yet yielded an indisputable result. It is shown that the well-known theories predict the possibility of finding the gravitational Lorentz forces on the Earth. It points to known experiments in which these forces are found. On the basis of this assumption, it is made that the gravitational radiation of cosmic objects can be detected on the Earth as a manifestation of the gravitational Lorentz forces. The construction of a gravitational antenna designed to detect gravitational waves is proposed. It is shown that such a design is much simpler than known gravitational antennas and telescopes.
