Assessment of Physicochemical and Bioactive Properties of Fresh and Dried Sweet Cherry Fruit
Authors: ALTIOK Duygu , OTAĞ Mustafa Remzi 
Published: June 2019

In this study, the changes in the pH, water soluble
dry matter (TSSM), color, total phenolic substance and antioxidant activity of
cherry (Prunus avium) grown in
Giresun by drying in laboratory type oven at three different temperatures (40,
50, 60 ° C) were investigated. The total phenolic content was determined by
Folin-Ciocalteu spectrophotometric method and the results were expressed as
Gallic Acid Equivalent (GAE). The antioxidant activity was determined by ABTS +
radical scavenging activity and the results were expressed as Trolox Equivalent
Antioxidant Capacity (TEAC). It was determined that the total drying time
decreased as the drying temperature increased, and the cherry flesh samples
dried in a shorter time than the whole cherry samples. It was found that the pH
of the whole cherry and cherry flesh samples dried at different drying
temperatures varied in the range of 4.08-4.45. When the color changes of the
cherry samples during drying were examined, it was determined that L * values
were not significantly affected by the increase of drying temperature but a *
value increased and b * values decreased. After drying, the total phenolic
substances in the extracts of flesh and whole cherry were found to be
362.58-347.26 mg GAE / 100g and 372.49-355.17 mg GAE / 100g, respectively.
Antioxidant activity values were determined as 14.70-20.59 µM trolox/g dry
sample and 15.51-27.46 µM trolox/g dry sample respectively in flesh and whole
cherry extracts. Because of the exposure
of the cherry samples to the high temperature and oxygen during drying, the total
phenolic content and consequently the antioxidant activity of the cherry
samples decreased in both whole cherry and cherry flesh samples

Forensic accountants are tasked with providing legal opinions in litigation. Besides that, there is also the role of forensic accountants in the field of law outside the court (non-itigation) for example in helping to formulate alternative settlement cases in disputes, formulation of compensation calculations and efforts to calculate the impact of termination / breach of contract. Investative audit, a form of audit or examination that aims to identify and uncover fraud or crime by using approaches, procedures and techniques commonly used in an investigation or investigation into a crime. Because the purpose of an investigative audit is to identify and disclose fraud or crime, the approaches, procedures and techniques used in investigative audits are relatively different from the approaches, procedures and techniques used in financial audits, performance audits or audits with other specific objectives. In an investigative audit, an auditor initiates an audit with presumptions / indications of possible fraud and crimes that will be identified and revealed through the audit to be carried out. Such conditions, for example, will affect who will be interviewed in advance or what documents must be collected first. In addition, in an investigative audit, if it has authority, the auditor can use procedures and techniques commonly used in the investigation and investigation of crimes, such as surveillance and searches. Fraud is the process of making, adapting, imitating or objects, statistics, or documents, with the intent to cheat. But we can prevent fraud and we can avoid fraud is very detrimental to various parties because it can destroy government and business. Fraud is in the form of corruption in its wider destructive power. Basically the scope of forensic accounting is fraud in the broadest sense.

The removal efficiency of cadmium ion was predicted through 11 neurons hidden layer, with a correlation coefficient of 0.9997 between ANN outputs and the experimental data and through sensitivity analysis, pH was found to be most significant parameter (25.13 %).The kinetic flotation order for cadmium ions almost first order and the removal rate constant (k) increases with decreasing the initial metal concentration.
Carbonized Copolymers Nonwoven Nanofibers Composite: Surface Morphology and Fibers Orientation
Authors: I. Waisi Basma 
Published: June 2019

Carbonized nonwoven nanofibers composite were fabricated using the electrospinning method of a polymeric solution composite followed by heat treatment including stabilization and calcination steps. The spun polymeric solution was a binary polymer mixture/organic solvent. In this study, two types of polymers (Polymethylmethacrylate (PMMA) and Polyethylene glycol (PEG)) were used separately as a copolymer with the base polymer (Polyacrylonitrile (PAN)) to prepare a binary polymer mixture in a mixing ratio of 50:50. The prepared precursor solutions were used to prepare the precursor nanofibers composite (PAN: PMMA) and (PAN: PEG). The fabricated precursors nonwoven fibers composite were stabilized and carbonized to produce carbon nonwoven nanofibers composite. The effect of the combined polymer type on the fiber size, fiber size distribution, and surface morphology of the prepared nonwoven nanofibers was studied. The nonwoven fibers orientation and surface morphology were characterized using field emission scanning electron microscope (FESEM). In addition, ImageJ software has been used to calculate the fiber size and fiber size distribution. Here, the obvious effect of the copolymer type on the surface morphology, fiber size, and fiber orientation has been demonstrated. Using a copolymer with PAN polymer led to increasing the fiber size. The carbonized nanofibers composite prepared using PEG polymer as a copolymer was more ordered fibers in comparison with the fiber orientation of carbon nanofibers based on pure PAN. In contrast of that, using PMMA as a copolymer resulted curly carbonized nonwoven nanofiber composite.

Authors: Saeb Salih Ibrahim , Ali Baker Hussain 
Published: June 2019

The objective of the conventional well testing technique is to evaluate well- reservoir interaction through determining the flow capacity and well potential on a short-term basis by relying on the transient pressure response methodology. The well testing analysis is a major input to the reservoir simulation model to validate the near wellbore characteristics and update the variables that are normally function of time such as skin, permeability and productivity multipliers.
Well test analysis models are normally built on analytical approaches with fundamental physical of homogenous media with line source solution. Many developments in the last decade were made to increase the resolution of transient response derivation to meet the complexity of well and flow media.
Semi-analytical modeling for the pressure transient response in complex well architecture and complex reservoirs were adopted in this research. The semi analytical solution was based on coupling the boundary condition of source function to the well segment. Coupling well-reservoir on sliced based technique was used to re-produce homogenous isotropic media from several source functions of different properties. The approach can model different well geometries penetrated complex reservoirs. A computer package was prepared to model the pressure transient response of horizontal, dual-lateral, multi-lateral wells in complex anisotropic reservoirs, multilayered, compartmentalized, system of various boundary conditions such as: bottom support aquifers, edge supported, gas caps, interference of injection. The validity of the proposed model was successfully checked by using the commercial simulator.

Published: June 2019

Introduction:mining has recently aroused substantial interest inRussia due to the rise in crypto-currency rates. Therefore, new coins are harder to obtain, and mining equipment turns more expensive. Computation capacities are provided by mining farms, and the number of their computation modules reaches 20 units, if operated by natural persons, and 300 – 5,000 units, if operated by major computation centres. One of the factors restraining the development of industrialscale mining, consists in high power consumption rates demonstrated by major computation centres. Therefore, the problem of high-quality power supply to mining farms gains relevance both in terms of the efficient use of electric power sources and in terms of the protection of expensive machines.Methods:the co-authors have analyzed power saving problems that accompany the incorporation of industrial mining farms, substantiated the need to design and develop the unique equipment, connectable to mining farms because the circulation of the reactive component of electric power between the source of alternate current and the accumulator causes losses of energy in the wires of the electric circuit. The overloading of the circuit by the reactive current causes the need to improve the capacity of the energy source, reduces the circuit voltage and makes it fluctuate. The co-authors have performed an overview of air and liquid-based cooling systems applied to mining farms. They also describe the principle of the cooling system involving submersion, which has a strong potential as a constituent component of major mining farms.Findings and discussion:the co-authors have formulated their idea aimed at the improvement of the performance of mining farms. They present a power saving system centered around the reactive capacity compensation, filtration of upper harmonics and compensation of voltage tilts.Conclusion:the co-authors have formulated the objectives of research in the area of power efficiency and capacity improvement at mining farms.
