The Origin of Cosmic Microwave Background Radiation

This paper explains the Olbers paradox and the origin of cosmic microwave background radiation (CMBR) from the viewpoint of the quantum redshift effect. The derived formula dispels the Olbers paradox, confirming that the CMBR originates from the superposition of light radiated by stars in the whole universe, not the relic of the Big Bang. The dark-night sky and CMBR are all caused by Hubble redshift—the physical mechanism is the quantum redshift of the photon rather than cosmic expansion. So this theory supports the infinite and steady cosmology.

Application of Microwave Radiation to Extractive Metallurgy

In applying the microwave radiation to extractive me-tallurgy,it is essential first of all to find the extent ofmicrowave energy absorbed by various minerals experi-mentally.In this paper,more than 25 kinds of commonuseful minerals have been individually irradiated by a 500W,2450 MHz microwave source in an enclosed quartzcrucible to ascertain their heating temperature in a definitetime.In addition,the reduction and cbloridization testswere also carried out on the titanomagnetite concentrateand pentlandite with microwave heating,respectively.These experiments indicate potential applications of util-izing microwave energy in extractive metallurgy.

Two-step method to extract seismic microwave radiation anomaly:Case study of M_s8.0 Wenchuan earthquake

The satellite remote sensing has become a promising technique for detecting earthquake and fault activities.But it is still very difficult to exactly extract the earthquake anomaly from the complicated remote sensing information.This paper presented a two-step method to extract the seismic microwave radiation anomaly related with earthquake,which could eliminate the stable influence of geography,terrain,coversphere and seasons, as well as the random influence of weather.Furthermore the two-step method was applied to analyze the anomaly of Wenchuan earthquake based on the data of AMSR-E.Microwave radiation anomalies were effectively detected related to the main shock and aftershocks.The extracted microwave radiation variation showed general features of three-stage:the positive radiation anomaly appeared around the epicenter in the first stage,quiet variation in the second stage,and abnormal area gradually moved to the epicenter in the third stage.After the main shock the microwave radiation anomalies distributed along the Longmenshan faults,and the epicenters of aftershocks were coincident with the anomaly area in space.

Effects of microwave radiation on brain energy metabolism and related mechanisms

With the rapid development of electronic technologies, anxiety regarding the potential health hazards induced by microwave radiation(MW) has been growing in recent years. The brain is one of the most sensitive target organs for microwave radiation, where mitochondrial injury occurs earlier and more severely than in other organs. Energy metabolism disorders do play an important role during the process of microwave radiation-induced brain damage. In this paper, we will review the biological effects of microwave radiation, the features of brain energy supply and consumption and the effects of microwave radiation on mitochondrial energy metabolism and potential related mechanisms.

0-10 KM TEMPERATURE AND HUMIDITY PROFILES RETRIEVAL FROM GROUND-BASED MICROWAVE RADIOMETER

Deviation exists between measured and simulated microwave radiometer sounding data. The bias results in low-accuracy atmospheric temperature and humidity profiles simulated by Back Propagation artificial neural network models. This paper evaluated a retrieving atmospheric temperature and humidity profiles method by adopting an input data adjustment-based Back Propagation artificial neural networks model. First, the sounding data acquired at a Nanjing meteorological site in June 2014 were inputted into the Mono RTM Radiative transfer model to simulate atmospheric downwelling radiance at the 22 spectral channels from 22.234 GHz to 58.8 GHz, and we performed a comparison and analysis of the real observed data; an adjustment model for the measured microwave radiometer sounding data was built. Second, we simulated the sounding data of the 22 channels using the sounding data acquired at the site from 2011 to 2013. Based on the simulated rightness temperature data and the sounding data, BP neural network-based models were trained for the retrieval of atmospheric temperature, water vapor density and relative humidity profiles. Finally, we applied the adjustment model to the microwave radiometer sounding data collected in July 2014, generating the corrected data. After that, we inputted the corrected data into the BP neural network regression model to predict the atmospheric temperature, vapor density and relative humidity profile at 58 high levels from 0 to 10 km. We evaluated our model's effect by comparing its output with the real measured data and the microwave radiometer's own second-level product. The experiments showed that the inversion model improves atmospheric temperature and humidity profile retrieval accuracy; the atmospheric temperature RMS error is between 1 K and 2.0 K; the water vapor density's RMS error is between 0.2 g/m^3 and 1.93 g/m3; and the relative humidity's RMS error is between 2.5% and 18.6%.

Effect of Low Level Subchronic Microwave Radiation on Rat Brain

Objective The present study was designed to investigate the effects of subchronic low level microwave radiation(MWR) on cognitive function,heat shock protein 70(HSP70) level and DNA damage in brain of Fischer rats.Methods Experiments were performed on male Fischer rats exposed to microwave radiation for 90 days at three different frequencies: 900,1800,and 2450 MHz.Animals were divided into 4 groups: Group I: Sham exposed,Group II: animals exposed to microwave radiation at 900 MHz and specific absorption rate(SAR) 5.953 × 10-4 W/kg,Group III: animals exposed to 1800 MHz at SAR 5.835 × 10-4 W/kg and Group IV: animals exposed to 2450 MHz at SAR 6.672 × 10-4 W/kg.All the animals were tested for cognitive function using elevated plus maze and Morris water maze at the end of the exposure period and subsequently sacrificed to collect brain tissues.HSP70 levels were estimated by ELISA and DNA damage was assessed using alkaline comet assay.Results Microwave exposure at 900-2450 MHz with SAR values as mentioned above lead to decline in cognitive function,increase in HSP70 level and DNA damage in brain.Conclusion The results of the present study suggest that low level microwave exposure at frequencies 900,1800,and 2450 MHz may lead to hazardous effects on brain.

The Derivation of the Cosmic Microwave Background Radiation Peak Spectral Radiance, Planck Time, and the Hubble Constant from the Neutron and Hydrogen

Purpose: The cosmic microwave background radiation, CMB, is fundamental to observational cosmology, and is believed to be a remnant from the Big Bang. The CMB, Planck time, tP, and the Hubble constant, H0, are important cosmologic constants. The goal is to accurately derive and demonstrate the inter-relationships of the CMB peak spectral radiance frequency, tP, and H0 from neutron and hydrogen quantum data only. Methods: The harmonic neutron hypothesis, HNH, evaluates physical phenomena within a finite consecutive integer and exponential power law harmonic fraction series that are scaled by a fundamental frequency of the neutron as the exponent base. The CMB and the H0 are derived from a previously published method used to derive tP. Their associated integer exponents are respectively +1/2, −3/4, and −128/35. Results: Precise mathematical relationships of these three constants are demonstrated. All of the derived values are within their known observational values. The derived and known values are: νCMB, 160.041737 (06) × 109 Hz, ~160 × 109 Hz;2.72519 K, 2.72548 ± 0.00057 K, H0 2.29726666 (11) × 10−18 s−1, ~2.3 × 10−18 s−1;and tP 5.3911418 (3) × 10−44 s, 5.39106 (32) × 10−44 s. Conclusion: The cosmic fundamental constants tP, H0, and CMB are mathematically inter-related constants all defined by gravity. They are also directly derivable from the quantum properties of the neutron and hydrogen within a harmonic power law.

Nanoparticles assisted microwave radiation:Fluid-rock interactions in oil reservoirs

Recently,many researchers have focused on the usage of electromagnetic waves in oil production and well stimulation,but so far the effect of these waves on the fluid and rock interaction and its simultaneous effect with nanoparticles have not been investigated.Fluid-rock interaction is one of the most important factors affecting fluid distribution in the reservoirs.In this study,the oil reservoir rock wettability alteration under electromagnetic heating and the presence of nanoparticles has been investigated.Three nanoparticles of TiO_2,Fe_(3)O_(4),and TiO_2/Fe_(3)O_(4)have been utilized.TiO_2 nanoparticles are commercially available,and the other mentioned nanoparticles are synthesized via a co-precipitation method.Citric acid has been used to modify surfaces of nanoparticles and stabilize them in water as the base fluid.Also,the adsorption of the nanoparticles on the rock surface has been determined.In the next step,the amount of oil outflow from the rock has been measured and reported as the external fluid imbibition.In this process,the nanoparticle performance in wettability alteration was investigated using pH and inductively coupled plasma(ICP)analyses.To better understand the governing mechanisms,oil viscosity was measured by mixing the oil with nanoparticles and put under irradiation.The results reveal that the microwave has a great ability to reduce oil contact angle with carbonate rock.In the presence of0.2 wt%Fe_(3)O_(4)nanoparticles,the contact angle was reduced from 155°to 19°after 28 min of irradiation,indicating strong rock hydrophilicity.Furthermore,microwave irradiation on Fe_(3)O_(4)nanofluid extracts75%of the oil from the rock.With microwave radiation,the pH of the nanofluid increases and hence,more nanoparticles are adsorbed on the rock which subsequently causes more rock dissolution.The viscosity change results prove that there is an optimal irradiation time of 5 min in which oil viscosity reduces from 481 cP to 410 cP and then increases to 827 cP.Moreover,the application of further nanoparticles diminishes the oil viscosity at optimum irradiation time in which Fe_(3)O_(4)has the most oil viscosity reduction,representing 481 cP to 200 cP at 50%microwave power level.

Simulated Solar Microwave Radiation Blocks the Formation of Biofilms

The article presents the results of the experimental study that was devoted to determining the blocking influence of the solar microwave radiation on the process of biofilm formation in Gram-positive and Gram-negative microorganisms. The microwave generator that allows simulating microwave “splashes” of the Sun in the frequency range (4.0 - 4.3 GHz) with the controlled intensity of radiation (from 50 μW/sm2 to 500 μW/sm2) was used for conducting this research. It is found out that the simulated solar radiation of the microwave range blocks the formation of the extracellular matrix by the opportunistic microorganisms. The results of this study confirm the hypothesis of the evolutionary nature of the leading role of the microwave radiation of the Sun in the life processes of organisms. The technology of the exposure on the microorganisms that was used in the experiment opens up the real prospects for reducing the persistent potential of microorganisms and improving the efficiency of the bacterial infections treatment.

Radiation Losses in the Microwave X Band in Al-Cr Substituted Y-Type Hexaferrites

We present a study on radiation losses in the microwave X band in Al-Cr substituted Y-type hexaferrites,namely Ba_2 Mg_2 Al_(x/2)Cr_(x/2)Fe_(12-x)O_(22)(x= 0, 0.5 and 1.0). The study is performed by means of a vector network analyzer, Fourier transform infrared spectroscopy, a vibrating sample magnetometer and x-ray powder diffraction.Ba_2 Mg_2 Fe_(12)O_(22) hexaferrite shows radiation loss of-37.25 dB(99.999% loss) at frequency 9.81 GHz, which can be attributed to its high value of saturation magnetization, i.e., 22.08 emu/g. Moreover, we obtain that magnetic properties have strong influence on the radiation losses.

Influence of Microwave Radiation on Properties and Structure of Fe_2O_3/SO_4^(2-) Solid Superacid Catalyst

The microwave radiation method was introduced to prepare the Fe2O3/SO solid superacid.Its structure and properties were investigated by means of X-ray diffraction and infrared spectrum analyses as well as measurement of magnetic susceptibility and rate of esterification. The structure of the superacids prepared in microwave field can be crystalline or non-crystalline, the latter has not been reported yet in literatures. Comparing with the traditional superacid, the non-crystalline Fe2O3/SO superacid prepared in microwave field has the highest magnetic susceptibility and catalytic activity. The di-coordination of Fe2O3 and SO and the S=O bi-bond were reinforced by microwave radiation, which is favorable for increasing the acid intensity of the Fe2O3/SO
