Published: March 2019

La interferencia electromagnética afecta el funcionamiento adecuado de los dispositivos electrónicos. Nuevos materiales celulares están mostrando su potencial de blindaje de la interferencia por radiación electromagnética gracias a sus características mecánicas y de absorción de energía que, combinadas con un coeficiente de reflexión de ondas electromagnéticas alto y una buena conductividad eléctrica, las convierte en un material útil para esta aplicación.
El objetivo de este trabajo es el de analizar el comportamiento de una espuma metálica de celda abierta como atenuador de la radiación electromagnética mediante la simulación computacional en ANSYS Electromagnetics. El sistema físico es modelado en un medio compuesto por aire, siendo el material seleccionado aluminio; posteriormente el sistema es sometido a campos electromagnéticos dinámicos producidos por una antena lineal. Los resultados obtenidos muestran que a partir de un campo magnético y eléctrico incidente de 1A/m y 5V/cm, respectivamente, el comportamiento en magnitud de estos campos se reduce conforme estos se internan en la matriz del material, hasta valores de 0.0691A/m para el campo magnético y 0.6573V/cm para el campo eléctrico.

In this paper, we investigate the basic characteristics of "magnetron sputtering plasma" using the target V2O5. The "magnetron sputtering plasma" is produced using "radio frequency (RF)" power supply and Argon gas. The intensity of the light emission from atoms and radicals in the plasma measured by using "optical emission spectrophotometer", and the appeared peaks in all patterns match the standard lines from NIST database and employed are to estimate the plasma parameters, of computes electron temperature and the electrons density. The characteristics of V2O5 sputtering plasma at multiple discharge provisos are studied at the "radio frequency" (RF) power ranging from 75 - 150 Watt and gas pressure (0.03, 0.05 and 0.007) torr. One can observe that the intensity of the emission lines increases with increasing the sputtering power. We find that the electron temperature excess drastically from 0.95 eV to 1.11eV when the emptying gas pressure excess from 0.03 to 0.05 Torr. On other hand excess electron temperature from 0.9 to 1.01 eV with increasing sputtering power from 100 to 125 Watt, while the electron density decrease from 5.9×1014 to 4.5×1014 cm-3 with increasing sputtering power. and electron density decrease with increasing of pressure from 4.25×1014 to 2.80×1014 cm-3, But the electron density maximum values 5.9×1014 at pressure 0.03 Torr.

The proliferation of cellular network enabled users through various positioning tools to track locations, location information is being continuously captured from mobile phones, created a prototype that enables detected location based on using the two invariant models for Global Systems for Mobile (GSM) and Universal Mobile Telecommunications System (UMTS). The smartphone application on an Android platform applies the location sensing run as a background process and the localization method is based on cell phones. The proposed application is associated with remote server and used to track a smartphone without permissions and internet. Mobile stored data location information in the database (SQLite), then transfer it into location API to obtain locations result implemented in Google Maps. Track a smartphone with fixed identifiers mostly SSN (SIM (Subscriber Identity Module) Serial Number) and IMEI (International Mobile Equipment Identity) derived from an identifying string unique to the user's device. The result located place is Moderate correct according to the (GSM) and (UMTS) cellular networks which is used for obtaining location information.
A New Cipher Based on Feistel Structure and Chaotic Maps
Authors: Et al. Al-Bahrani 
Published: March 2019

Chaotic systems have been proved to be useful and effective for cryptography. Through this work, a new Feistel cipher depend upon chaos systems and Feistel network structure with dynamic secret key size according to the message size have been proposed. Compared with the classical traditional ciphers like Feistel-based structure ciphers, Data Encryption Standards (DES), is the common example of Feistel-based ciphers, the process of confusion and diffusion, will contains the dynamical permutation choice boxes, dynamical substitution choice boxes, which will be generated once and hence, considered static,
While using chaotic maps, in the suggested system, called Chaotic-based Proposed Feistel Cipher System (CPFCS), we made the confusion and diffusion in dynamical behavior based on Standard and Lorenz maps. The first is used for substitution, and the second one for permutation operations .A proposed cryptographic system uses the same work (the same way) for both enciphering and deciphering. The proposed cipher operates on more than 500 bytes (4000-bit) readable text blocks by six round computing. Within the basic operator of the cipher, i.e., in the function of the round F, a dynamical lookup table 2D standard map system is used to enhance the complexity and diffusion of the unreadable text. Also, a 3D Logistic map used for key sequence generator and chaos based dynamical Initial Permutation (dynamical IP) are used to increase the diffusion and confusion. Three different image sizes and three different text length were implemented in CPFCS. The results of the proposed system and security tests improve the applicability of PFCS in the data protection and security.
Well Integrity Protection Using Corrosion Inhibitor Treatment System for Sour Gas Producers in Bahrain Field
Authors: Shamlooh Mohamed , Abdelrady Sayed , Buasali Mohamed , Farouque Khurram 
Published: March 2019

Abstract

Objectives/Scope
Gas wells of the Bahrain Field in the Kingdom of Bahrain suffer from corrosion and scale issues due to the presence of water, Carbondioxide (CO2), and a high Hydrogen Sulphide (H2S) content in the formation. The current method applied to overcome these issues involves bullheading a corrosion inhibitor batch treatment. However, high costs and low effectiveness are driving a shift from batch treatments to continuous downhole treatment techniques. This paper describes the process of converting to continuous downhole treatments.

Methods, Procedures, Process
The process of continuously injecting a corrosion inhibitor downhole is much more efficient and cost effective than bullheading the well with a corrosion inhibitor. This application reduces the potential of scale buildup and avoids well deliverability reduction problems. Additionally, the injection system may be used to continuously inject multi-blend chemicals downhole and can thereby treat other problems downstream and reduce the need for surface inhibition.
Designing the system with the appropriate chemicals and tubing material is the key to success. The selection of materials and chemicals should take into account the CO2, H2S, temperature, and pH concentration in the candidate well.

Results, Observations, Conclusions
The chemical injection string can be installed into a live well using a capillary unit, without the need to shut-in or choke-back production. This can be carried out as a rigless installation similar to a coiled-tubing operation, but on a much smaller scale. The capillary unit is small and compact, and is mounted onto a truck or a trailer. The unit can be mobilized and de-mobilized for operation rapidly and easily, saving time and cost.
Routine maintenance to the injection system is crucial for a long-term successful application. The qualification of the chemicals should be stringent and must allow for friction loss through such small inner diameters (IDs), however it must also withstand the pressures, temperatures, fluids, and extreme downhole conditions that it will face.
Using the continuous downhole injection system will positively impact well integrity, improve completion lifetime, assure production continuity, reduce downtime and treatment operating costs, and avoid coiled-tubing descaling operational costs.

Novel/Additive Information
Installing a downhole treatment system can also be used for other purposes if needed, such as H2S management, deliquification, scale inhibition, controlling paraffin/asphaltene, and treating downhole pumps.

Abstract
Background

Nutritional status is an important prognostic factor in Amyotrophic Lateral Sclerosis (ALS). We wished to study the safety, tolerability and efficacy of nutritional counseling with or without an mHealth application to maintain or increase body weight in ALS, compared to standard care.

Methods

In this randomized open-label, standard-of-care-controlled, single-center clinical trial, we randomly assigned adults with ALS to one of three nutritional interventions: counseling by their physician or nurse (“standard care”), counseling by a registered dietitian (RD) (“in-person”), or counseling supported by a mHealth app (“mHealth”). Both intervention arms received tailored nutrition recommendations and recorded dietary intake and weight biweekly (mHealth) or monthly (in-person). The primary outcome of weight and secondary and tertiary outcomes of calorie intake, ALSFRS-R, and quality of life (QOL) were recorded at each clinic visit and analyzed in an ITT mixed model analysis.

Results

A total of 88 participants were enrolled of whom 78 were included in this analysis. The three arms were well-balanced except for excess males in the mHealth arm and greater weight lost at baseline in the in-person arm. Participants in the mHealth arm increased their calorie intake at month 3 to an average of 94% (95% CI: 85, 103) of recommended calories, compared to 81% (95% CI: 72, 91, p= 0.06 vs. mHealth) in the standard care arm. After 6 months, calorie intake and change in weight was not different among the three arms. QOL scores in the mHealth arm were stable over three months (0.3 points, 95% CI: -1.7, 2.2) compared to worsening in standard care (-2.1 points, 95% CI: -4.0, -0.2, p = 0.09 vs. mHealth), but all scores declined by six months. ALSFRS-R total scores declined by an average of -2.6 points (95% CI: -5.1, -0.1) over six months in the mHealth arm (p=0.13 vs. standard care) compared to -5.8 points (95% CI: -8.2, -3.4, p=0.74 vs. standard care) in the in-person and -5.2 points (95% CI: -7.6, -2.9) in the standard care arm.

Conclusions

Nutritional counseling is safe but did not increase weight compared to standard care in ALS patients.

Published: March 2019

Purpose: to describe the characteristic clinical signs and to study the causes of the development of an unfavorable prolonged course of bacterial corneal ulcers of central localization, and to improve treatment effectiveness. Material and methods. A total of 289 patients with central bacterial corneal ulcers were examined. Two types courses of bacterial corneal ulcer were distinguished: favorable (acute and subacute) and unfavorable (prolonged subacute and prolonged chronic forms). Blood (122 samples) and scrapings from corneal ulcers (110 samples) were examined in a nested polymerase chain reaction (PCR) to detect deoxyribonucleic acid (DNA) of simple herpes virus (HSV) 1 and 2 types, virus Epstein–Barr (VEB), human herpes virus (HHV)-6, and HHV-7. To detect autoimmune sensitization to the corneal antigens, migration inhibition reaction of leukocytes (MIRL, 215 samples) was used. Results. In patients with unfavorable course of the disease, blood and corneal HHV DNA was detected in 88.7 % of cases, while with a favorable course only 10 % of cases showed the presence of HHV DNA (р < 0.002). In all patients, HHV type 6 was predominating. Autosensitivity to corneal antigens was detected in 8 (10.4 %) out of 77 patients at the end of the first week of the disease, and as the disease progressed, the number of patients with an autoimmune component increased to reach 63.2 % (48 of 76). The inclusion of antiviral and immunosuppressive drugs into the routine treatment plan led to complete epithelialization of the cornea within 5–10 days. Сonclusion. The protracted course of bacterial corneal ulcers was found to be caused by a mixed herpes-bacterial infection, which is corroborated by the effectiveness of the modified treatment tactics.

Testing properties governing the durability of lime-based repair mortars
Authors: Papayianni Ioanna , Hughes John 
Published: March 2019

Lime-based mortars (LM(s)) seem to be preferred in repairing historic structures. The long-term performance of repair LM(s) is closely related to durability issues concerning the old structure substrate, the new repair mortars and interface between the two aforementioned materials, which is also much influenced by the technique of mortars application.
Durability is a multifunctional property affected by a number of parameters, including local environmental conditions. However, experience showed that some of the characteristics of materials play a dominant role in assessing the durability of repair LM(s) and have a direct impact on longevity of the repaired structure.
This paper presents review of research/case studies papers and Master/PhD theses supervised by the members of RILEM TC 277 LHS. Through the review and evaluation of research and common practice concerning durability challenges, we anticipate to find answers to questions arising in assessing durability of repair LM(s), such as:

The most often encountered failures due to mortar durability inadequacy
The mortar properties/characteristics that seem to be influential on durability
The test methods used for testing the durability of LM(s) and comments related to their applicability and performance
The importance of quality control and on site execution practices
