TL;DR: In this paper, the effects of two types of additive for the soil (i.e., lime/cement) on the geotechnical and engineering properties of the soil are studied.
Abstract: One of the possible problems that may be encountered by execution of future projects such as highway, mass construction, and also industrial buildings in Farmahin (in the northwestern of Arak, Iran) is low strength and large deformation of the field soil. Such soils can be treated with the general traditional soil stabilization methods such as lime or cement stabilization methods. In the current study, the effects of two types of additive for the soil (i.e., lime/cement) on the geotechnical and engineering properties of the soil are studied. The results of the study indicate that optimum moisture content, maximum dry unit weight, and plasticity index are affected by the addition of cement or lime. Also cement treatment results in increase of unconfined compressive strength (UCS) of the soils significantly, whereas the test results indicate that there is an optimum of lime content so that the addition of a few percentage of lime results in increase of unconfined compressive strength. Generally, improvement in mechanical behaviors of the soil due to cement treatment was noticeably higher than lime treatment. Also the results of tests show that the change of UCS of the specimens with the initial water content and curing time is significant, so that decreasing of initial water content or increasing of curing time results in increase of USC of the specimens. Also, the current study sought to characterize the relationship between secant modulus (E50) and UCS, curing time, and cement or lime content.

TL;DR: In this paper, the authors compared the interlayer space and thermal stability of the nanofiller at different initial silane concentrations and found that the chemical grafting value for 15mmol silane is greater than that of the 9mmol initial concentration (0.15mmol/g clay).

TL;DR: The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors.
Abstract: The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors. While the organization of the book is similar to previous editions, major emphasis has been placed on disorders that affect multiple organ systems. Important advances in genetics, immunology, and oncology are emphasized. Many chapters of the book have been rewritten and describe major advances in internal medicine. Subjects that received only a paragraph or two of attention in previous editions are now covered in entire chapters. Among the chapters that have been extensively revised are the chapters on infections in the compromised host, on skin rashes in infections, on many of the viral infections, including cytomegalovirus and Epstein-Barr virus, on sexually transmitted diseases, on diabetes mellitus, on disorders of bone and mineral metabolism, and on lymphadenopathy and splenomegaly. The major revisions in these chapters and many

TL;DR: This study reviews several of the most commonly used inductive teaching methods, including inquiry learning, problem-based learning, project-basedLearning, case-based teaching, discovery learning, and just-in-time teaching, and defines each method, highlights commonalities and specific differences, and reviews research on the effectiveness.
Abstract: Traditional engineering instruction is deductive, beginning with theories and progressing to the applications of those theories Alternative teaching approaches are more inductive Topics are introduced by presenting specific observations, case studies or problems, and theories are taught or the students are helped to discover them only after the need to know them has been established This study reviews several of the most commonly used inductive teaching methods, including inquiry learning, problem-based learning, project-based learning, case-based teaching, discovery learning, and just-in-time teaching The paper defines each method, highlights commonalities and specific differences, and reviews research on the effectiveness of the methods While the strength of the evidence varies from one method to another, inductive methods are consistently found to be at least equal to, and in general more effective than, traditional deductive methods for achieving a broad range of learning outcomes

TL;DR: This report provides a well-formulated framework for decision-makers and health service planners to implement strategies for comprehensively managing chronic conditions and describes eight essential elements for improving and creating innovations in the care of chronic conditions.
Abstract: Chronic health conditions have been on the rise across the world. But few health care systems, have proved able to cope with managing this dramatic increase in chronic conditions. This report from the World Health Organization (WHO) provides a comprehensive framework for the prevention framework for the prevention and management of Chronic health conditions around the world. Chronic health conditions were defined in this report as “health problems that persist across time and require some degree of health care management”. This new report addresses how policy makers can take effective and innovative action to tackle these conditions. The report addresses the following issues: Exploring chronic conditions, including how and why they are increasing, what is their economic impact on patients, families, communities, and governments, and how to reduce their prevalence. The deficits in current systems of health to successfully manage chronic conditions because the acute care model dominates health care systems. The acute care model increased health care expenditures without improving populations health status. A new framework for health care systems to improve care for chronic conditions. This framework is comprised of fundamental components within the patient, health care organization and community, and policy levels. These components were described as “building blocks” that can be used to re-design a health care system to manage long-term health problems more effectively. The report describes eight essential elements for improving and creating innovations in the care of chronic conditions. These elements include: Supporting a shift in attitudes, so that decision­ makers, health workers and patients are aware that a shift in resources from the acute, episodic model of care is needed to meet the different of chronic conditions. Building political commitment to the process of preventing and managing chronic conditions. Avoiding fragmentation of services, to ensure that the care for chronic conditions is integrated. To align and analyze policies which affect chronic conditions, such as agricultural regulations, labor laws and health education. To use new, team care models and evidence-based skills for managing chronic conditions, worth more efficient use of health care personnel. To re-oriented Health care for chronic conditions around the patient and family. To support patients within their communities, because communities can fill a crucial gap in health services that are not provided by organized health care. To emphasize prevention, as many of the complications of chronic conditions can be prevented or reduced. This report provides a well-formulated framework for decision-makers and health service planners to implement strategies for comprehensively managing chronic conditions.

TL;DR: G-frames as mentioned in this paper are generalized frames which include ordinary frames, bounded invertible linear operators, as well as many recent generalizations of frames, e.g., bounded quasi-projectors and frames of subspaces.
