This exploration set up a limited number of user equipment (UEs) while taking into account the three-dimensional (3D) distance between UEs and base stations (BSs), multislope line of sight (LOS) and non-line of sight (n-LOS), idle mode capability (IMC), and third generation partnership projects (3GPP) path loss (PL) models. In the current work, we examine the relationship between the height and gain of the macro (M) and pico (P) base stations (BSs) antennas and the ratio of the density of the MBSs to the PBSs, indicated by the symbol β. Recent research demonstrates that the antenna height of PBSs should be kept to a minimum to get the best performance in terms of coverage and capacity for a 5G wireless network, whereas ASE smashes as β crosses a specific value in 5G. We aim to address these issues and increased the performance of the 5G network by installing directional antennas at MBSs and omnidirectional antennas at Pico BSs while taking into consideration traditional antenna heights. The authors of this work used the multi-tier 3GPP PL model to take into account real-world scenarios and calculated SINR using average power. This study demonstrates that, when the multi-slope 3GPP PL model is used and directional antennas are installed at MBSs, coverage can be improved 10% and area spectral efficiency (ASE) can be improved 2.5 times over the course of the previous analysis [1]. Similarly to this, the issue of an ASE crash after a base station density of 1000 has been resolved in this study.

INTRODUCTION M ACRO, micro, pico, and femtocells are only a few of the several network technologies that are combined in heterogeneous cellular networks (HetNets) to provide effective coverage and capacity for various locations and use cases. The main goal of HetNets is to optimize network performance by dynamically allocating network resources to satisfy the changing requirements of various devices and services. HetNets use a combination of different radio access technologies (RATs) and frequencies and employ advanced techniques such as load balancing, self-organization, and interference management to provide efficient and effective network operation. In addition, HetNets use small cells to supplement macro cells and provide increased capacity and coverage in stadiums, shopping centres, and urban centres are examples of high-density areas. The 3GPP (3rd Generation Partnership Project) is working to define the standards and protocols for HetNets, and there have already been a number of commercial HetNet deployments in various regions of the world. The 3rd generation partnership project (3GPP) radio access network (RAN) plenary has authorised a work package for its Release 18, which represents a major evolution

Mixed cryoglobulinaemia is itself a low-grade B-cell lymphoproliferative disorder which may progress to non-Hodgkin's lymphoma (NHL). Studies from Europe and Asia have found a prevalence of hepatitis C virus infection in non-Hodgkin's lymphoma patients as high as 34%. Other viral infections are also associated with non-Hodgkin's lymphoma. We speculated that non-Hodgkin's lymphoma patients in the midwestern USA would have an increased prevalence of hepatitis C infection. We tested 73 patients with NHL and 20 controls with Hodgkin's disease for anti-HCV antibodies by EIA-2. Only 1/73 patients and no control subject was positive for anti-HCV. The anti-HCV positive patient had no identifiable risk factors for hepatitis C, and ALT was persistently normal. HCV-RNA testing by RT-PCR was negative. Thus, none of 73 non-Hodgkin's lymphoma patients could be confirmed to have hepatitis C infection. In a second part of the study, of 438 patients with HCV infection followed an average of 28.1 months, only one patient developed non-Hodgkin's lymphoma. We conclude that in our population, non-Hodgkin's lymphoma is not associated with hepatitis C virus infection. Based on these results and review of the literature, there are marked regional differences in the prevalence of hepatitis C infection in Non-Hodgkin's lymphoma.

Biologically important compounds like DNA bases, and amino acids showed irreversible behavior when oxidized electrochemically. The reversible redox potentials for such systems (say, irreversible electrochcemical systems) were estimated by analyzing the cyclic voltammograms recorded at different scan rates. The approach presents here is relatively simple and easy for obtaining reversible redox potential of electrochemically irreversible systems. Moreover, for the case of thymine, the obtained reversible oxidation potential also used to establish the PCET-pathways for oxidation of thymine in water.

Homogenous seeds of okra were drilled in rows 75cm apart from each other on well prepared seed bed on February 15, 2011. Where as, the feeding potential of predatory spiders on these pests were evaluated in a laboratory condition. Four prominent predatory spider species such as; Hippasa agelenoides, Cheiracanthium danieli, Argyrodes argentatus and Drassodes sp. were recorded throughout the data collection. Thus, there feeding potential was observed under the laboratory conditions at 25±2 o C and the pests were provided. The overall consumption by these two spider species; C. danieli and H. agelenoides consumed maximum (12.30±1.23) and (10.10±1.07) where as, the minimum (9.65±1.39) and (8.35±2.09) pest population by A, argentatus and Drassodes sp. The correlation of 143 Journal of Agriculture and Sustainability all predatory spiders was highly significant with jassid (r 2 =0.84**), whitefly (r 2 =0.94**), thrips (r 2 =0.88**) and mites (r 2 =0.94**). But the temperature had the low positive correlation with the population among predatory spiders (r 2 =0.45 ns), jassid (r 2 =0.38 ns), whitefly (r 2 =0.46 ns), thrips (r 2 =0.45 ns) and mites (r 2 =0.53 ns). In the behavior of relative humidity had also low positive correlation with the population of predatory spiders (r 2 =0.31 ns), jassid (r 2 =0.14 ns), whitefly (r 2 =0.25ns), thrips (r 2 =0.34 ns) and mites (r 2 =0.22 ns). However, predatory spiders were found abundantly with their carnivorous habits among the population that showed synchronization with the sucking insect pests in okra crop.

The characters considered were plant height, leaf area, leaf fresh weight, leaf dry weight, number of leaves per plant, number of sympodial branches per plant, number of bolls per plant, boll weight and seed cotton yield per plant. Irrigation treatments were three; normal seven irrigations schedule upto 150 days of crop maturity, four irrigations (medium stress) upto 150 days of crop maturity and two irrigations upto 150 days of maturity (stress conditions). General and specific combining ability analysis revealed that the mean squares for GCA and SCA were significant for all the characters under all the irrigation treatments. The general combining ability estimates of parents for all the characters under study and under all the irrigation treatments were highest for CRIS-134 except for boll weight under four irrigations where CRIS-52 excelled all the parents. Similarly, CRIS-9 followed CRIS-134 in GCA estimates scoring, and ranked second in all irrigation treatments and for all the characters except for boll weight under seven irrigations (where MARVI was second highest), under four irrigations here CRIS-110 was second highest) and under two irrigations where CRIS-52 was second highest. Thus GCA estimates of parents for boll weight are affected by drought conditions and therefore in the selection of desirable parents to give desirable combinations for boll weight, only those combinations be selected with highly significant difference for boll weight towards bigger boll size. Testing of such combinations is recommended to continue upto F 5 and F 6 generations to get homogeneity of high performing lines/advance strains. As regards to specific combining ability estimates, hybrid CRIS-9 x CRIS-134 gave highest SCA value of 11.54 for seed cotton yield under seven irrigations treatment, while CRIS-9 x CRIS-191 gave highest SCA value of 9.91 under four irrigations treatment for seed cotton yield. Under stress conditions (two irrigations), CRIS-9 x CRIS-134 gave highest SCA value of 12.35 for seed cotton yield. As the seed cotton yield is the main and important attribute for almost all the stakeholders, therefore it is suggested that the particular hybrid CRIS-9 x CRIS-134 may be produced which in present study, has been isolated to give highest SCA values under normal as well as under drought conditions (only two irrigations).

Fresh animals (adults) of both the sexes were used in all the experiments, and the gastrocnemius (skeletal) muscles were dissected out, reptilian buffer solution was used to keep dissected muscles moist & used during experimentation. The muscle sample solutions were prepared by heating/drying and incinerating/ashing the muscle tissues, treating with acid and deionized water respectively. These samples were then used for the estimation of Na+, K+ & Cl-ions. The water content was found as percent wet muscle weight. The average mean values of water content and these osmotically active ionic contents were found to fall significantly (P<0.05) from peak winter towards peak summer & vice versa. The seasonal effects of these parameters, studied for the first time in the skeletal muscle of Uromastix hardwickii, displayed changes as the animal passed from one seasonal phase to another. Hence seasonal changes are invariably associated with changes in environmental temperature, and definitely responsible to change the active behavior and homeostasis of these animals from summer towards winter by variations in blood borne humoral and hormonal substances along with significant changes in osmolality and tissue water contents.

Zinc oxide NWs have shown very high voltage generation and they are possible to grown on plastic, paper and cotton. Since we with these substrates can get a new freedom to bend and also stretch the NWs and to incorporate them into new applications they are of great potential. Here we will describe the mechanical and piezoelectric properties of ZnO NWs grown on ordinary clean room paper and on cotton fabrics substrates as well as possibility of coating the ZnO NWs to maximize the output generated power. An enhancement of 160 times in the piezo-potential was observed from ZnO NWs coated with P3HT p-type polymer compared to non-coated NWs.

Different approaches are compared along with their experimental results to show the variation in the amount of superplasticity by varying above mentioned parameters. At room temperature magnesium alloys usually have poor formability but recent studies of some alloys such as ZE10, AZ31, AZ61 AZ60, AZ80 and AZ91 are pointing that by varying the temperature along with grain size and strain rate improved formability is possible or even superplastic forming of these alloys can be achieved to meet the demands of automotive, aircraft and other weight conscious industries.

Br• was generated through electrochemical oxidation of bromide ion (Br–). First the reactivity of Br• atom-free radical vis a vis its dimerization to form Br2, was studied using cyclic voltammetry and spectroelectrochemistry. Through these techniques it was ascertained that the substrates understudy and the under experimental conditions used, underwent reactions with Br• and not with dibromine (Br2). The monitoring of the reactions of Br• with glycine and cytosine led us to conclude that whereas cytosine reacted with Br• as simple chemical reaction (EC mechanism), glycine underwent a catalytic reaction (EC′ mechanism).
