Abstract:
Link residual closeness (LRC) is a new sensitive characteristic for network vulnerability analysis. LRC measures the vulnerability even when the removal of links does not disconnect the network. In this paper, the robustness of wheel type network topologies is modeled and analyzed via LRC in the face of possible link destruction.

Abstract:
The study of human thermoregulation is one of the most developed areas of modern physiology and medicine. This is due to the important role of temperature in normal and pathological conditions. Directly or indirectly almost all systems and organs are involved in maintaining of relatively constant temperature in the body, since their normal functioning is closely related to the temperature of the internal environment (temperature homeostasis). Currently, the existence of two systems of thermoregulation is recognized: a physiological organ-based system with a center in the hypothalamus and a mol

Abstract:
Eutrophication as well as the removal of algae by the drinking water industry received dedicated attention in past three decades. An interdisciplinary approach will assist catchment and water purification managers to work to the same future – algal blooms in reservoirs dominated by the “ideal algae” which can be removed by conventional unit treatment processes. This paper will provide a futuristic picture of resource and product quality management, based on a historic perspective of eutrophication and algal removal research.

Abstract:
Weight thresholding (WT) is a method intended to decrease the number of links within weighted networks that may otherwise be excessively dense for network science applications. WT aims to remove links to simplify the network by holding most of the features of the original network. Here, we test the robustness and the efficacy of the node attack strategies on real-world networks subjected to WT that remove links of higher weight (strong links). We measure the network robustness along node removal with the largest connected component (LCC). We find that the real-world networks under study are ge

The construction of ‘hard’ impermeable surfaces in urban areas results in the increased flow of stormwater runoff and its associated pollutants into downstream receiving waters.

Abstract:
The organization of real networks usually embodies both regularities and irregularities, and, in principle, the former can be modeled. The extent to which the formation of a network can be explained coincides with our ability to predict missing links. To understand network organization, we should be able to estimate link predictability. We assume that the regularity of a network is reflected in the consistency of structural features before and after a random removal of a small set of links. Based on the perturbation of the adjacency matrix, we propose a universal structural consistency index t

Our numerical application considers phosphorus driven eutrophication, agricultural phosphorus abatement and fisheries targeted on cyprinids on a coastal bay in the Baltic

Removal of agricultural pipes used in crop support and greenhouse agriculture is manpower-intensive. However, most agricultural workers are elderly.

The optimization parameters are the length of each link and the initial link angle of the device. The driving force, according to the design parameters, was calculated by applying the theory of k

Abstract:
Many inference algorithms develop the time-domain connection of the direct by employ a Kalman filter base on a first-order (or sometimes second-order) estimate of the time-varying channel amid a norm based on link toning (CM), or on the Minimization of Asymptotic Variance (MAV). To decrease the complexity of the high-dimensional RW-KF for combined opinion of the multi-path multifaceted amplitudes, we suggest using an inferior dimensional RW-KF that estimate the compound amplitude of each path separately. We demonstrate that this amounts to a simplification of the joint multi-path Kalman increa

Abstract:
AbstractFunctional polyketones were chemically cross-linked for the softening of hard water, i.e. for the removal of the divalent cations Ca2+ and Mg2+. Elemental analysis, FT-IR spectroscopy, solubility- and swelling-experiments were used to demonstrate the occurrence of the cross-link reaction. Testing the different compounds for their Ca2+ and Mg2+ removal capacity assessed the structure-functionality of the polymers. The corresponding water-insoluble resins were then tested for their Ca2+ and Mg2+ removal capacity-performance being explained in terms of their chemical structure. Ion adsorp

Abstract:
Industrial growth generates waste, where produced water (PW) poses a challenge due to its chemical complexity. Concerns about potential health effects, including a link to Alzheimer's disease, arise with flocculants like aluminum sulfate. Studies indicate that Moringa oleifera seeds have coagulation activity. Thus, this study aimed to compare the oil/water removal efficiency of PW through flocculation between aluminum sulfate and M. oleifera seed-based coagulants in saline and aqueous media. The synthetic matrix was treated with these flocculants, revealing a notable reduction in oil and greas

Abstract:
This study investigates the relationship between surface properties and microstructural characteristics of photocatalytic composites and their impact on air purification efficiency. High-resolution energy-dispersive X-ray spectroscopy (EDS) mapping and mercury intrusion porosimetry (MIP) were employed to analyze photocatalyst distribution and pore structure quantitatively. The findings demonstrated a strong correlation between TiO2 coverage on the photoactive surface and NO removal rates and between pore structure characteristics and NO2 generation rates.

Abstract:
The appendix has historically been considered a rudimentary organ with an unknown function. Currently, its role in the human body has a special place. It has been proved that it is a "piggy bank" for commensal microorganisms and acts as an immunological organ. The impact of appendectomy on ulcerative colitis and Crohn’s disease has been debated for more than 30 years. Removal of the appendix at an early age has been reported to reduce the risk of ulcerative colitis but lead to a progressive course of Crohn’s disease. These observations led to the postulate that there may be an association betw

In this study, we investigated feature-based approaches for improving the link prediction performance for location-based social networks (LBSNs) and analysed their performances. We developed new features based on time, common friend detail and place category information of check-in data in order to make use of information in the data which cannot be utilised by the existing features from the literature. We proposed a feature selection method to determine a feature subset that enhances the prediction performance with the removal of redundant features by clustering them. After clustering feature

It is important to have full medical education before starting this procedure, so as to prevent complications resulted from nasogastric tube insertion. The use of nasogastric tubes may bring with many kinds of complications. The goal of this article is to re-evaluate the application, care and possible dangers of nasogastric tube insertion.

It is a minimally invasive cholecystectomy wherein inside of the abdomen is visualize with the help of camera introduced through 4 small incisions to remove the gallbladder by using long tools. The aim of the present study is to evaluate the correlation between abdominal wall hernia (paraumbilical hernia) and laparoscopic cholecystectomy in the Iraqi patients (n=100). The age of the patients was 25 to 36 years. Before surgery, the red blood cells, white blood cells and serum urea were found to be 105.67±3.00

Abstract:
The study aims to treat artificial wastewater contaminated with copper (II) ions by reverse osmosis using (SEPA CF042 Membrane Test Skid-TFC BW30XFR). Several concentrations of feedstock were prepared. Different operating pressure, temperature, and flow rate were applied. The effect of these operating conditions on both the amount of Cu (II) removal and the permeate flux was monitored. The results of the study revealed that both the permeate flux and Cu (II) removal amount were directly proportional to the operating pressure and feed temperature but inversely proportional to the feed concentra
