<p>In this study, a novel green cationic hydrogel of cationic polyacrylamide composite have been prepared and investigated. The synthesis of green cationic polyacrylamide composite was evaluated for its solubility in water. The reactions were performed using acrylamide monomer, solvent, catalyst (clay fin called maghnite) and solution of  H<sub>2</sub>SO<sub>4</sub> (0.25 M), with the system under microwave irradiation (160 ºC) for 4 min. Major factors affecting the polymerization reaction were studied with a view to discover appropriate conditions for preparation of the composite. The cationic polyacrylamide obtained is the subject of future studies of modification and transformation. The resulting polymer has been characterized by a variety of characterization techniques, such as: Fourier Transform Infrared Spectra and <sup>1</sup>H NMR spectra.  Copyright © 2016 BCREC GROUP.

THE CLINICIAN has long been aware of the fact that iron deficiency anemia is most prevalent during infancy. Continuing studies of iron metabolism have disclosed many factors which help explain the basic mechanisms of the anemia and the peculiar vulnerability of the infant. The following comments pertain to a review of the subject appearing in this issue of Pediatrics. The concept that the baby is born with "iron stores," in terms of reserve depots, is no longer tenable. Almost the entire quota of iron with which the baby begins life is that contained in his circulating hemoglobin. This initial endowment is influenced by three major factors: 1) the length of gestation; 2) the amount of blood transferred from placenta to infant in the first few minutes after delivery, and 3) prenatal factors affecting intrauterine hematopoiesis, an aspect which may be highly significant since even in normal full-term infants the concentration of hemoglobin in cord blood has been found to vary within a range of 5 gm./100 ml. of blood.

The Way

Much of the knowledge of small mammal ecology in Australia has come from Elliott trapping, however the results of these studies are influenced by the way in which trapping is carried out. We review some of the major factors affecting the results of Elliott trapping: trap spacing, local placement, presence of odours on the trap (from conspecifics, similar species, predators, and humans), and duration of trapping. Most factors clearly influence trapping results and should be routinely considered, and preferably controlled, in future studies which use Elliott traps.

The Subject

The various published biographies and biographical notices of G.I. Gurdjieff (c.1865-1949) are of diverse style, quantity and content. While some have made considerable contributions to the subject, most attempts have reacted for or against Gurdjieff’s status as what might call an ‘Enlightened Master’. Little biographical writing on Gurdjieff has questioned the scope, reliability and prejudices of the sources. Further, possible resources have been neglected. The development in Gurdjieff’s ideas is often overlooked, his life is not sufficiently related to that development, and the lack of comparative research has failed to highlight Gurdjieff’s unique contributions. This article is structured in four parts. The first is an introduction, followed by an overview of existing biographical studies of Gurdjieff. The third part addresses bias in these studies, and this is followed by suggestions for future studies. It is concluded that fieldwork regarding the biography of Gurdjieff has been hampered by imperfect methodology. However, with better use of the source material, some of which has only recently been discovered, and a rigorous use of sources, a more balanced and nuanced picture of Gurdjieff’s life, and the development of his ideas and methods, should emerge.

الملخّصيتعلق هذا البحث بموضوع دية القتل الخطأ في الحوادث المرورية في الفقه الإسلامي في العصر الحاضر لكثرة وقوعها وحاجة الناس إلى بيان أحكامها من حيث كيفية تقديرها. وتحرير الخلاف في دية المرأة، ومسألة دية الجنين في حال تعرضه للموت في بطن أمه نتيجة الحادث المروري، أو في حالة تعرضه للإجهاض والموت، وتناول أيضًا دية شخصين إذا ماتا نتيجة اصطدام سيارتين؛ فكيف تقدَّر الدِّية؟ وعالج البحث مسألة العاقلة في الوقت الحاضر التي تساعد الطرفين (الجاني والمجني عليه وذلك بجمع الدية وإعطائها للمجني عليه). وذلك من خلال استخدام المنهج الاستقرائي والمنهج المقارن: حيث يتم من خلاله جمع النصوص المتعلقة بالموضوع، وآراء العلماء المتقدمين، والمعاصرين، والمقارنة بينهما لمعرفة نقاط الاتفاق والاختلاف، لتجلية معالم الموضوع، وتسهيل مناقشتها بصورة دقيقة، ثم بيان الرأي الراجح. وقد توصلت الدراسة إلى أنَّ دية القتل في الحوادث المرورية في العصر الحاضر تساوي بالدينار الذهبي، الذي يساوي 4.250 جرامًا من الذهب، أو بما يساويها من النقد. وأنَّ الراجح هو تساوي دية الرجل مع دية المرأة. وفي حالة عدم وجود العاقلة لابأس من إنشاء شركة تعاونية لمساعدة من وقع منه الحادث.الكلمات المفتاحية: الدِّية، حوادث المرور، دية المرأة، دية الجنين، العاقلة. Abstract         This research addresses the subject of blood money for unintended manslaughter in traffic accidents according to Islamic jurisprudence in the present era due to the frequency of their occurrence and the need for people to understand the legal provisions concerning determining the amount. In this regard, we seek to clarify the disagreements regarding the blood money for women and foetuses that die in the mother’s womb as a result of traffic accidents or abortion. We also address the issue of blood money for two people who die as a result of collision between two cars. We also examine the issue of ʿĀqilah (those who pay the blood money) who helped the two parties (the offender and the victim by collecting blood money and giving it to the victim). To clarify these issues, we use the inductive approach and comparative method wherein we collect the various texts on the subject, and the views of classical and contemporary scholars to engage in a comparison between them in order to identify the points of agreement and disagreement between views. From here, we also hope to identify the major factors pertaining to such issues in order to facilitate a precise and concrete discussion to arrive at the most correct opinion. The study found that blood money for manslaughter in traffic accidents in the present era is equal to a gold dinar, which is equal to 4.250 grams of gold, or its cash equivalent. We advocate that the correct view is that the amount of blood money paid to a man is equal to that of a woman, and that in the absence of an ʿĀqilah it is possible to form a cooperative or mutual fund to render assistance to the victim.Keywords: blood money, traffic accidents, women, foetus, ʿĀqilah.

This study confirmed the general belief of urban planners that mixed land use promotes walking in Seoul, a metropolis in East Asia, by analyzing the effect of mixed land use on the travel mode choice of housewives and unemployed people who make non-commuting trips on weekdays. Using binomial logistic regression of commuting data, it was found that the more mixed a neighborhood environment’s uses are, the more the pedestrians prefer to walk rather than drive. The nonlinear relationship between the land use mix index and the choice to walk was also confirmed. Although mixed land use in neighborhoods increased the probability of residents choosing walking over using cars, when the degree of complexity increased above a certain level, the opposite effect was observed. As the density of commercial areas increased, the probability of selecting walking increased. In addition to locational characteristics, income and housing type were also major factors affecting the choice to walk; i.e., when the residents’ neighborhood environment was controlled for higher income and living in an apartment rather than multi-family or single-family housing, they were more likely to choose driving over walking.

Abstract Background This study aimed to determine the possible prognostic factors correlated with the treatment modalities of tubo-ovarian abscesses (TOAs) and thus to assess whether the need for surgery was predictable at the time of initial admission. Materials and methods Between January 2012 and December 2019, patients who were hospitalized with a TOA in our clinic were retrospectively recruited. The age of the patients, clinical and sonographic presentation, pelvic inflammatory risk factors, antibiotic therapy, applied surgical treatment, laboratory infection parameters, and length of hospital stay were recorded. Results The records of 115 patients hospitalized with a prediagnosis of TOA were reviewed for the current study. After hospitalization, TOA was ruled out in 19 patients, and data regarding 96 patients was included for analysis. Twenty-eight (29.2%) patients underwent surgical treatment due to failed antibiotic therapy. Sixty-eight (70.8%) were successfully treated with parenteral antibiotics. Medical treatment failure and need for surgery were more common in patients with a large abscess (volume, > 40 cm3, or diameter, > 5 cm). The group treated by surgical intervention was statistically older than the patients receiving medical treatment (p < 0.05). Conclusions Although the treatment in TOA may vary according to clinical, sonographic, and laboratory findings; age of patients, the abscess size, and volume were seen as the major factors affecting medical treatment failure. Moreover, TOA treatment should be planned on a more individual basis.

As one-dimensional (1D) nanofiber, carbon nanotubes (CNTs) have been widely used to improve the performance of nanocomposites due to their high strength, small dimensions, and remarkable physical properties. Progress in the field of CNTs presents a potential opportunity to enhance cementitious composites at the nanoscale. In this review, current research activities and key advances on multiwalled carbon nanotubes (MWCNTs) reinforced cementitious composites are summarized, including the effect of MWCNTs on modulus of elasticity, porosity, fracture, and mechanical and microstructure properties of cement-based composites. The issues about the improvement mechanisms, MWCNTs dispersion methods, and the major factors affecting the mechanical properties of composites are discussed. In addition, large-scale production methods of MWCNTs and the effects of CNTs on environment and health are also summarized.
