Foliar-applied Amcoton® and potassium thiosulfate enhances the growth and productivity of three faba beans varieties by improving photosynthetic efficiency

Amcoton® [a mixture of 0.45% naphthalene acetic acid and 1.25% naphthalene acetamide] and potassium thiosulfate (KTS) play a crucial role in growth and productivity enhancement of faba beans plants. The current study aimed to evaluate the potential impact of Amcoton® and KTS foliar application on growth, yield, and photosynthetic efficiency in three faba beans varieties (i.e. Giza-843, Nubaria-3, and Sakha-4) during 2016-17 and 2017-18 seasons. Results exhibited that Amcoton® and/or KTS significantly increased growth indices (e.g., plant height, number of leaves and branches, leaves area, shoot dry weight), yield component, and chlorophylls contents and photosynthetic efficiency in comparison with untreated control plants. Giza-843 showed significantly higher growth and productivity when compared to Nubaria-3 and Sakha-4. Seed yield significantly positive correlated with leaves area, chlorophyll content, plant height, number of branches, pods and seeds per plant, pod dry weight and biological yield. Results obtained through this study highlighted the potential impact of Amcoton® and/or KTS on enhancing the growth and productivity of faba beans plants by improving leaf chlorophylls contents and photosynthetic efficiency

Performance Evaluation of Different Universal Steganalysis Techniques in JPG Files

Steganalysis is the art of detecting the presence of hidden data in files. In the last few years, there have been a lot of methods provided for steganalysis. Each method gives a good result depending on the hiding method. This paper aims at the evaluation of five universal steganalysis techniques which are “Wavelet based steganalysis”, “Feature Based Steganalysis”, “Moments of characteristic function using wavelet decomposition based steganalysis”, “Empirical Transition Matrix in DCT Domain based steganalysis”, and “Statistical Moment using jpeg2D array and 2D characteristic function”. A large Dataset of Images -1000 images- are subjected to three types of steganographic techniques which are “Outguess”, “F5” and “Model Based” with the embedding rate of 0.05, 0.1, and 0.2. It was followed by extracting the steganalysis feature used by each steganalysis technique for the stego images as well as the cover image. Then half of the images are devoted to train the classifier. The Support vector machine with a linear kernel is used in this study. The trained classifier is then used to test the other half of images, and the reading is reported The “Empirical Transition Matrix in DCT Domain based steganalysis” achieves the highest values among all the properties measured and it becomes the first choice for the universal steganalysis technique

ICI and PAPR enhancement in MIMO-OFDM system using RNS coding

The Inter-Carrier-Interference (ICI) is considered a bottleneck in the utilization of Multiple-Input-Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems, due to the sensitivity of the OFDM towards frequency offsets which lead to loss of orthogonality, interference and performance degradation. In this paper Residue Numbers as a coding scheme is impeded in MIMO-OFDM systems, where the ICI levels is measured and evaluated with respect to conventional ICI mitigation techniques implemented in MIMO-OFDM. The Carrier-to-Interference Ratio (CIR), the system Bit-Error-Rate (BER) and the Complementary Cumulative Distribution Function (CCDF) for MIMO-OFDM system with Residue Number System (RNS) coding are analyzed and evaluated. The results had demonstrated a performance of transmission model with and without RNS

In Situ Surgery: Is It Safe ? (Experience with 60 cases)

Background/Purpose: Neonatal surgical unit (NSU) is the area of a hospital where sick babies having surgical problem go once they are born. Performing in-situ surgery (ISS) in the NSU is relatively a new concept that is gaining popularity in the last decade. Critically ill neonates who are too ill to transfer to the operating room can undergo safe surgery in the NSU environment of a fully-equipped pediatric hospital. Transfer of the critically ill neonates is time consuming, utilizing manpower and requiring suitable portable ventilators and extensive monitoring equipments. Materials & Methods: This is a prospective study conducted on 60 neonates admitted in the surgical neonatal unit of the Cairo University pediatric hospital (Abou-Elrish) and where subjected to surgical procedures in the unit itself. The patients were categorized into 3 groups: The First group was the group at the beginning of the study for which minor procedures were selected. The second group was those neonates that were operated upon on emergency base for which transfer could be hazardous. The last group included those patients on high settings of ventilation and critically ill neonates with extensive monitoring. Results: There was no mortality in the study related to the procedures itself. Group I patients: the time of the surgical procedures was longer than that in the OR and no increase in the infection rate was noticed. Group II in which emergency procedures were carried on showed also increase in operating time but better perioperative circumstances regarding secondary insult to viable structures & less infection rate. Group III: no significant change in outcome in comparison to cases transferred to OR except that the perioperative circumstances were better for the surgeon, anesthesiiologist & nursing teams. Conclusion: NSU is a safe place for performing in-situ surgery (ISS) without increased risk of infection. Successful operative intervention within NSU requires good planning and cooperation between anesthesiologist, surgeons, neonatologist and nursing staff. Maximum benefit is observed in neonates who have definite risk attached to transfer to operating room. Index Word: In-Situ Surgery (ISS) – Neonatal Surgical Unit (NSU)

Performance Enhancement of MIMO-OFDM using Redundant Residue Number System

Telecommunication industry requires high capacity networks with high data rates which are achieved through utilization of Multiple-Input-Multiple-Output (MIMO) communication along with Orthogonal Frequency Division Multiplexing (OFDM) system. Still, the communication channel suffers from noise, interference or distortion due to hardware design limitations, and channel environment, and to combat these challenges, and achieve enhanced performance; various error control techniques are implemented to enable the receiver to detect any possible received errors and correct it and thus; for a certain transmitted signal power the system would have lower Bit Error Rate (BER). The provided research focuses on Redundant Residue Number System (RRNS) coding as a Forward Error Correction (FEC) scheme that improves the performance of MIMO-OFDM based wireless communications in comparison with current methods as Low-Density Parity Check (LDPC) coders at the transmitter side or equalizers at receiver side. The Bit Error Rate (BER) performance over the system was measured using MATLAB tool for different simulated channel conditions, including the effect of signal amplitude reduction and multipath delay spreading. Simulation results had shown that RRNS coding scheme provides an enhancement in system performance over conventional error detection and correction coding schemes by utilizing the distinct features of Residue Number System (RNS)

Accidental Death of Construction Worker due to Unintended Nail Gun Discharge: a Case Report

Background: In spite of being rare, intracranial nail gun injury represents one of the fatal penetrating head injuries.Case Report: Here we report a case of intracranial nail gun injury in a 28 years old well-trained construction worker who left the electric nail gun on the edge of the window to pick up one of his tools from the ground. Unfortunately, his leg got entangled in the nail gun cable and thus the nail gun dropped on the ground firing a nail that killed the worker.Conclusion: To the best of our knowledge, this first time death from nail gun injury is reported in the Arab world; although, there are previous reports of survivable nail gun cardiac injuries and cranial injuries from Saudi Arabia. Thus, it is important to raise public awareness about such cases in order to reduce the occurrence of nail gun injuries. Moreover, health and safety inspections mandated and supported by law, might be much more effective in reducing such injuries

A Review of Applicability of Banning (Hajre) in Jurisprudence from the Perspective of Forensic Medicine

The topic of ward is among the important topics in jurisprudence and Forensic Medicine. Banning literally means prohibiting. The term of prohibition means preventing someone from being involved in financial or non-financial affairs and is called being banned. A person is banned from all affairs such as an unlettered person or some of the affairs such as a dying person. Banning has two forms; it sometimes is in the interests of the one banned from and his/her rights and sometimes for the benefit and the right of others. The objective of this brief article is an evaluation of extent banning applicability in Forensic Medicine topics and its relation with concepts and logics of the Islamic law

Multi-level Multi-objective Quadratic Fractional Programming Problem with Fuzzy Parameters: A FGP Approach

The motivation behind this paper is to present multi-level multi-objective quadratic fractional programming (ML-MOQFP) problem with fuzzy parameters in the constraints. ML-MOQFP problem is an important class of non-linear fractional programming problem. These type of problems arise in many fields such as production planning, financial and corporative planning, health care and hospital planning. Firstly, the concept of the -cut and fuzzy partial order relation are applied to transform the set of fuzzy constraints into a common crisp set. Then, the quadratic fractional objective functions in each level are transformed into non-linear objective functions based on a proposed transformation. Secondly, in the proposed model, separate non-linear membership functions for each objective function of the ML-MOQFP problem are defined. Then, the fuzzy goal programming (FGP) approach is utilized to obtain a compromise solution for the ML-MOQFP problem by minimizing the sum of the negative deviational variables. Finally, an illustrative numerical example is given to demonstrate the applicability and performance of the proposed approach

Response of lettuce to Cd-enriched water and irrigation frequencies

This pot experiment was an attempt to investigate a broad response of lettuce to different cadmium (Cd) levels of irrigation water (0, 5, 10 and 20 mg l-1) under different irrigation intervals (1, 2 and 4 days). The results showed that increased level of soil Cd through irrigation eventually decreased the yield of lettuce in all cases; however, in some cases yield was increased with lower doses of Cd application. No injury symptoms were observed other than plant height and yield reduction. Shoot dry weight proved to be the most sensitive parameters to the cadmium, especially under water stress conditions. The results also showed that the concentrations of nutrient elements in lettuce shoot were suppressed by water stress. The presence of cadmium in irrigation water did not significantly affect the absorption of nutrient elements by plants except for Fe. Shoot Cd concentration and its uptake decreased with increasing irrigation frequencies and the reverse trend occurred with increasing Cd levels of irrigation water. However, the values were higher than recommended guideline in all conditions. Also, shoot Cd content showed a significant positive correlation with the final accumulated Cd concentration of soil and was expressed by a plateau model under the dry irrigation regime and linear models at other irrigation intervals. Overall, shoot Cd concentration was predicted by using a simple linear regression model regardless of evapotranspiration and transpiration rate of plant.Key words: Cadmium toxicity; chemical composition; irrigation frequency; lettuce
