Abstract
During the past few decades, the technologies of the higher-shot densities, larger perforating guns and tubing-conveyed perforation (TCP) combined well testing have been used widely used for well completions. This results in a large increase of impact loads in the tubing during TCP. The safety of the tubing is directly related to the success of perforation combined well test,which is the key link in the oil and gas production. In this study, the influence factors of perforating impact load have firstly been analyzed. Also the dynamic response of tubing during TCP in three dimensions has been studied by numerical simulation. According to the computing results, the vulnerable parts of tubing during TCP have been found, where the axial impact load is the strongest and it is concluded that the axial shock absorber has the optimal installation position to achieve the best shock absorption effect, which is verified by the case. This study proposes a novel method for the safety analysis of the tubing, which has important significance to provide guidance for the design of field perforating operations and to improve security.

Abstract
In hadron therapy, the accelerated ions, interacting with the body of the patient, cause the fragmentation of both projectile and target nuclei. The fragments interact with the human tissues depositing energy both in the entrance channel and in the volume surrounding the tumor. The knowledge of the fragments features is crucial to determine the energy amount deposited in the human body, and - hence - the damage to the organs and to the tissues around the tumor target.
The FOOT (FragmentatiOn Of Target) experiment aims at studying the fragmentation induced by the interaction of a proton beam (150-250 MeV/n) inside the human body. The FOOT detector includes an electronic setup for the identification of Z ≥ 3 fragments integrated with an emulsion spectrometer to measure Z ≤ 3 fragments. Charge identification by nuclear emulsions is based on the development of techniques of controlled fading of the particle tracks inside the nuclear emulsion, that extend the dynamical range of the films developed for the tracking of minimum ionising particles. The controlled fading strongly depends on temperature, relative humidity and treatment duration.
In this study the performances in terms of charge separation of proton, helium and carbon particles, obtained on a batch of new emulsion films produced in Japan are reported.
Recent developments in resonance ionization mass spectrometry for ultra-trace analysis of actinide elements
Authors: Raeder Sebastian , Kneip Nina , Reich Tobias , Studer Dominik , Trautmann Norbert , Wendt Klaus 
Published: June 2019

Abstract
Resonance ionization mass spectrometry is an efficient tool to detect minute amounts of long-lived radio-isotopes in environmental samples. Applying resonant excitation and ionization with pulsed laser radiation within a hot cavity atomizer enables the sensitive detection and precise quantification of long-lived actinide isotopes. Due to the inherently element selective ionization process, this method ensures ultimate suppression of contaminations from other elements and molecules. The characterization of in-source resonance ionization of the actinide elements U, Th, Np, and Am using a compact quadrupole mass spectrometer (QMS) setup are discussed.

Authors: Dogan Ibrahim , Eser Baris , Kayadibi Huseyin 
Published: June 2019

Abstract

Objective
We aimed to investigate the effects of Ramadan fasting on renal functions in patients with stage 3 and 4 chronic kidney disease.

Materials and methods
The study was conducted in Ramadan month which was between June and July. Patients were evaluated before Ramadan, the week immediately following the end of the Ramadan, and 3 and 6 months after Ramadan.

Results
Twenty-four fasting (mean age of 68 ± 13 years) and 55 non-fasting individuals (mean age of 69 ± 9 years) were included in this study. There was no statistically significant difference for creatinine levels in the first week after Ramadan in both groups compared to levels before Ramadan (p = 0.070, p = 0.470, respectively). The groups were compared according to the criteria of deterioration in renal function (reduction of 25% in GFR and 30% increase in serum creatinine levels). There were no statistically significant differences between the two groups according to these two criteria (p = 0.452, p = 0.660, respectively). In univariate and multivariate logistic regression analysis, the presence of diabetes mellitus and proteinuria were found to be independent risk determinants of renal dysfunction.

Conclusion
Patients with diabetes mellitus and prominent proteinuria may constitute critical patient groups for renal function deterioration during Ramadan fasting.
Amduat-Exemplare von Thutmosis I.: Weitere Fundstücke im Grab KV 38
Authors: Abdel Ghany Khaled 
Published: June 2019

Summary
This article deals with the further exploration in tomb KV 38 in the Valley of Kings. In the course of this exploration in early 2018 I discovered more small mud-plaster fragments of the Amduat book. These different Amduat fragments can be identified as a part of the fourth, sixth, seventh, eighth and tenth hour of the book of Amduat. Therefore, these Amduat fragments prove that possibly the cliff walls of the tomb of king Thutmose I were originally encased and decorated with a complete corpus of the book of Amduat (long version). After an examination of the displayed scenes and their comparison with similar sections of the Amduat from tomb KV 34 it turned out that both specimens show clear differences and that both tombs have manifold artistic variations. Therefore, both specimen are originate from different reigns and were not made by the same king.
Der heliopolitanische Türpfosten mit der 2. Annaleninschrift Sesostris’ I.
Authors: Hernández Roberto Díaz 
Published: June 2019

Summary
A Heliopolitan inscription in a temple door post from Sesostris I’s times was published by Daressy in 1903. It has since then been almost entirely disregarded by Egyptologists despite its relevance on Sesostris I’s policy regarding endowments to Egyptian temples. This paper is the first historical and philological study of such a document and it aims to shed some new light on Sesostris I’s reign. It comprises four parts —dating and purpose of the temple door post (I); general remarks on the text (II); transcription and transliteration (III); explanatory notes (IV).

Summary
Publication of a block statue (JE 36668) with a separate fragmentary base (JE 36669). Both objects came from the Karnak Cachette and are on display in the Cairo Museum. The statue owner, a man named Ḏd-ḥr, held a number of important priestly titles, such as: jt-nṯr, ḥm-nṯr, ḥm-ḏw, and rdwy-nṯr of Amun at Karnak. The statue can be dated, on stylistic grounds, to the post-Persian Period.
De la lecture des graphies synthétiques de noms de couronnement ptolémaïques

Published: June 2019

Summary
In the present study, when a comparison is made between the combination of divine attributes s
ḫ
m and onX represented at the end of the “long complete” cartouches, and those held by the divinities inside “synthetic complete” cartouches of Ptolemy V and Ptolemy XII, the reading sXm-onX-Jmn is acceptable. But, when the same method is applied to the cartouches of Ptolemy IX Soter II, the reading becomes problematic. We are trying, then, to examine the reading of the Coronation name of this king.

Published: June 2019

Abstract
Meiotic recombination shuffles genetic variation and promotes correct segregation of chromosomes. Rates of recombination vary on several scales, both within genomes and between individuals, and this variation is affected by both genetic and environmental factors. Social insects have extremely high rates of recombination, although the evolutionary causes of this are not known. Here, we estimate rates of crossovers and gene conversions in 22 colonies of the honeybee, Apis mellifera, and 9 colonies of the bumblebee, Bombus terrestris, using direct sequencing of 299 haploid drone offspring. We confirm that both species have extremely elevated crossover rates, with higher rates measured in the highly eusocial honeybee than the primitively social bumblebee. There are also significant differences in recombination rate between subspecies of honeybee. There is substantial variation in genome-wide recombination rate between individuals of both A. mellifera and B. terrestris and the distribution of these rates overlap between species. A large proportion of interindividual variation in recombination rate is heritable, which indicates the presence of variation in trans-acting factors that influence recombination genome-wide. We infer that levels of crossover interference are significantly lower in honeybees compared to bumblebees, which may be one mechanism that contributes to higher recombination rates in honeybees. We also find a significant increase in recombination rate with distance from the centromere, mirrored by methylation differences. We detect a strong transmission bias due to GC-biased gene conversion associated with noncrossover gene conversions. Our results shed light on the mechanistic causes of extreme rates of recombination in social insects and the genetic architecture of recombination rate variation.
Supply management and the business activities of Ontario meat processors
Authors: Hansen Sterne Rita , Van Duren Erna 
Published: June 2019

Canadian supply management policies in dairy, poultry and eggs have been hotly debated for over 50 years. During the most recent renegotiation of the North American Free Trade Agreement (NAFTA) in 2017-2018, the U.S. threatened to cancel NAFTA if concessions were not made to Canada’s supply management policies in agriculture. During the renegotiation, many arguments for and against supply management in agriculture were repeated, some were updated, and some newer perspectives relating to sustainability and social responsivity were more enthusiastically discussed. Most arguments critical of supply management have been developed using economic analyses of market and industry-level impacts of supply management. On the other hand, supportive arguments are often qualitative, focus on the survival of smaller farms and generally lack empirical investigation based on application of relevant theory. This paper uses management theory to investigate the impact of supply management of management and business activities on food processing firms. We use a framework that links business activities with the broad regulatory environment to interpret evidence from a study of independent meat processors in Ontario, Canada, particularly those that processed turkey, which is a supply managed sector; and pork, which is not. Results suggest that the broad regulatory environment facing Ontario meat processors is of greater concern to managers of independent processing businesses than the specific regulatory environment of supply management. Results also suggest the value creation activities and strategies used by a business may affect how managers assess opportunities and challenges in this specific regulatory environment.

Hepatoprotective and nephroprotective effects of Trigonella foenum-graecum L. (Fenugreek) seed extract against sodium nitrite toxicity in rats
Authors: ATİLA USLU Gözde , USLU Hamit , ADALI Yasemen 
Published: June 2019

Introduction: Feeding habits and environmental factors may rival genetic susceptibility as etiological factors related to various cancers. Humans are continuously exposed to many synthetic food additives, one of which is sodium nitrite (NaNO2). There is a direct correlation between increases in consumption of nitrite-treated products and incidence of tissue damage, hepatotoxicity, nephrotoxicity and some types of cancer. The objective of this study was to investigate the protective effects of Trigonella foenum-graecum (TFG) on NaNO2-induced hepatotoxicity and nephrotoxicity.
Methods: Forty rats were randomly assigned (10 per group) to control (physiological saline solution), TFG (150 mg/kg/day), NaNO2 (80 mg/kg/day), and NaNO2+TFG (80 mg/kg/day + 150 mg/kg/day) groups. This group was offered TFG seed extract two hours before NaNO2. At the end of three months, the rats were decapitated, and blood, kidney and liver tissues were removed.
Results: Three months of oral administration of NaNO2 increased serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), urea, creatinine, and pro-inflammatory cytokine levels in the liver and kidney tissues [except for liver Interleukin 1 alpha (IL-1a)] of rats. Serum AST, ALT, urea, creatinine, liver IL-6, and kidney tumor necrosis factor-a (TNF-a), IL-6, IL-1a levels significantly decreased in the NaNO2+TFG group compared to the NaNO2 group. Pathological examinations, it was determined show that exogenously administered TFG could alleviate the effects of NaNO2 hepatotoxicity and nephrotoxicity.
Conclusions: Our results suggest that exogenous TFG mitigates NaNO2-administration induced hepatotoxicity and nephrotoxicity. TFG extract exerted antioxidative and anti-inflammatory effects, and played a significant role in preventing hepatic and renal damage induced by chronic NaNO2 administration.
Lack of association between 4 key TNF-alpha promoter polymorphisms and hepatitis C virus infection in a population of Egyptian patients
Authors: Ghoneim Ahmed M. 
Published: June 2019

Introduction: With 170 million chronic hepatitis C virus (HCV) cases worldwide, HCV is considered a major life-threatening pathogen. HCV is a crucial causative of liver cirrhosis and hepatocellular carcinoma. Tumor necrosis factor-alpha (TNF-alpha) is thought to be a mediator in the development of viral hepatitis. Because HCV is epidemic in Egypt, this study aimed to characterize the distribution of TNF-alpha gene promoter polymorphisms and their relation to TNF-alpha expression in HCV patients.
Methods: Four promoter polymorphisms; −1031T/C, −863C/A, −857C/T, and −308G/A, were studied by restriction fragment length polymorphism in a population of Egyptian HCV patients.
Results: Compared to healthy subjects, none of these polymorphisms were associated with HCV infection. The wild-type −1031T, −863A, −857C, and −308G alleles were highly prevalent in the studied population. Sequencing the promoter region spanning the four studied polymorphisms in some subjects did not reveal any difference in the nucleotide variance pattern, compared with the TNF-alpha reference sequence. Relative TNF-alpha mRNA expressions in HCV patients and healthy subjects were statistically indifferent.
Conclusion: Since previous studies confirmed an increase in TNF-alpha level in case of viral infections, this study focuses on mechanisms of post-transcriptional and posttranslational modifications of TNF-alpha gene in HCV patients, which decode the genetic factors linked to HCV infection and severity.
A javasolt, diagnosztikus szemléletű talajosztályozási rendszer szerves szénre vonatkozó osztályozási egységei és definíciói
Authors: Fuchs Márta , Szegi Tamás , Csorba Ádám , Michéli Erika

Összefoglalás
A szerves szén igen jelentős összetevője a talajoknak. Meghatározza a talajok számos fizikai, kémiai, biológiai és nedvesség gazdálkodási tulajdonságát és sokrétű környezeti funkcióit, többek között termékenységét, vízszűrő-, és szolgáltató képességét, pufferkapacitását, vagy a biológiai sokféleség megőrzésében játszott szerepét. A modern osztályozási rendszerekben a szerves szén mennyiségi és mélységi megjelenése diagnosztikus egységek és magasabb rendszertani egységeknek is gyakran alapja.
Diagnosztikus szemléletű hazai talajosztályozási rendszerünk kidolgozásakor megvizsgáltuk a hazai genetikus osztályozás szervesanyagra vonatkozó kritériumait, részletesen elemeztük a TIM adatbázis adatait és figyelembe vettük a nemzetközi standardokat. Törekedtünk olyan diagnosztikai egységek, altípus és változati tulajdonságok meghatározására, melyek az osztályozás támogatásán túl, önmagukban is fontos információt szolgáltatnak a különböző alkalmazásoknak.
Eredményeink szerint a TIM adatbázis tanulmányozása, a szerzők saját talajleíró tapasztalata, továbbá a szervesszén-tartalomra irányuló adatigény indokolja további mennyiségi intervallumok meghatározását az osztályozás alacsonyabb (altípus és változati tulajdonság) szintjén.
Vizsgálatunk további fontos eredménye, hogy rámutat, a földes részre vonatkoztatott szervesszén-tartalom nem elég a feltalajok diagnosztizálására. A durva rész arány, a telítettségi viszonyok, a szín, a szerkezet további fontos kritériumok a feltalajok, illetve a felszíni diagnosztikai szintek definiálásában. Ugyanakkor a szerves szén mennyiségi-, és mélységi határértékeinek egységes, típustól független meghatározása fontos információt szolgáltat a talajok sok szempontú megítélésben.
Javaslatunkban a szervesszén-tartalomra vonatkozóan nyolc felszíni diagnosztikus talajszint, egy felszín alatti diagnosztikus talajszint, és egy diagnosztikus talajanyag került meghatározásra. Az osztályozás alacsonyabb szintjein további 5 kategória bevezetését javasoltuk a talajokban megjelenő szervesszén-tartalom részletesebb jellemzésének biztosítása érdekében.
A javasolt rendszerben összesen 20 altípus -, és 2 változati tulajdonságban jelenik meg szervesszén-tartalomra, vagy olyan diagnosztikus talajszintre vonatkozó követelmény, amely definíciójában a szervesszén-tartalom (is) szerepel.
Az egyes elemek azonos értelmezése lehetővé teszi a típustól független térbeli kiterjedésének meghatározását.

Abstract: The proportion of elderly patients is getting increased in the developed countries as a consequence of which pharmacotherapy takes a more and more important place in the healthcare system. Important biological alterations are characteristic for the elderly subjects, which have effect on the pharmacokinetics and pharmacodynamics of the pharmaceuticals. Gradually decreased kidney function may demand the modification of the administration of the pharmaceuticals. Certain pharmaceuticals and drug-interactions are potentially dangerous for this population. Therefore several factors have to be taken into account in conjunction with the therapy of elderly patients including co-morbidities, cognitive function and the social state. At the same time, the risk–benefit ratio of the pharmaceuticals is the worst among elderly patients with pharmaceutical therapy including polypragmasy. Thus, it is inevitable for the development of geriatric pharmacotherapy that the physiologic alteration of elderly has to be taken into account not only in the daily practice but also during the development and formulation of a pharmaceutical. The present paper gives an overview of the most important factors influencing the pharmacotherapy of the elderly. Orv Hetil. 2019; 160(23): 896–907.
