Almost two decades today, the topic ofhas extensively been researched in urban sociology, urban planning, and human geography, and numerous Western-Centric studies have linked the redevelopment of the abandoned, contaminated, vacant or derelict sites to sustainable urban regeneration and achieving smart cities and sustainability goals in general. Yet, until this day, the concept has received little academic and practical attention in Middle Eastern contexts.Western contexts on the other hand including Europe, UK and USA continue to offer unique perspectives on approachingin ways that reduce the alarming spatial cluttering and addressdisparities and spatial segregation in addition to achieving economic and environmental goals, and similar to the global scene, brownfield sites make a large portion of the post-industrial city of Amman, the capital of Jordan. However, with the lack of a systematic definition for the urban phenomenon objectives, methods to identifying potential brownfield sites and evaluating theof their redevelopment that takes into consideration context particularities, and with the absence ofapproaches that include the local community in the decision-making regarding these spaces, city planners fail to include the increasingly growing number of brownfield site that proliferate their cities in the urban planning practice.Through the examination of literature discussions on objectives, approaches, classification systems, methodologies, assessment and evaluation tools for the support of design anddecisions for brownfield regeneration in different contexts, and through looking at the numerous potential alternatives for brownfield sites regeneration these contexts highlight, this paper bids tothe importance of developing context specific,tools tailored for the Middle Eastern case.Building on the above, this paper identifies five potential brownfield typologies in the context of Amman; (1) residual planning outcomes; (2) discontinued mines and quarries; (3) unfinished mega-projects; (4) contaminated and hazardous sites, and; (5) miscellaneous abandoned sites and buildings, and ends on the note that looking at the increasing demand to meeting smart growth and sustainability needs, these urban landscapes may function as catalysts for achieving comprehensive sustainable urban regeneration.

Portosystemic collateral formation in cirrhosis plays an important part in events that define the natural history in affected patients. A detailed understanding of collateral anatomy and hemodynamics in cirrhotics is essential to envisage diagnosis, management, and outcomes of portal hypertension. In this review, we provide detailed insights into the historical, anatomical, and hemodynamic aspects to portal hypertension and collateral pathways in cirrhosis with emphasis on the various classification systems.

Objective. To systematically review the international literature for internal nasal septal deviation classification systems and summarize them for clinical and research purposes. Data Sources. Four databases (including PubMed/MEDLINE) were systematically searched through December 16, 2015. Methods. Systematic review, adhering to PRISMA. Results. After removal of duplicates, this study screened 952 articles for relevance. A final comprehensive review of 50 articles identified that 15 of these articles met the eligibility criteria. The classification systems defined in these articles included C-shaped, S-shaped, reverse C-shaped, and reverse S-shaped descriptions of the septal deviation in both the cephalocaudal and anteroposterior dimensions. Additional studies reported use of computed tomography and categorized deviation based on predefined locations. Three studies graded the severity of septal deviations based on the amount of deflection. The systems defined in the literature also included an evaluation of nasal septal spurs and perforations. Conclusion. This systematic review ascertained that the majority of the currently published classification systems for internal nasal septal deviations can be summarized by C-shaped or reverse C-shaped, as well as S-shaped or reverse S-shaped deviations in the anteroposterior and cephalocaudal dimensions. For imaging studies, predefined points have been defined along the septum. Common terminology can facilitate future research.

Crop diseases are the main threat to agricultural products. Fast, accurate, and automatic detection of diseases can help to overcome this problem. Literature suggests, machine learning techniques are capable of achieving these goals in near real-time. This article presents a comprehensive review of machine learning techniques for crop disease detection and classification. Existing plant disease classification systems are explored and commonly used processing steps are investigated. Analysis of machine learning techniques, accuracy factor, and current state-of-the-art in this domain have been reviewed and presented through this manuscript. The survey resulted in the identification of the strengths and limitations of existing techniques and provides a road map for future research works. These would help researchers to understand and pursue machine learning applications in the field of disease detection and classification

Various classification systems have been proposed to describe furcation lesions and Glickman’s classification for many years seems to have been the most widely utilized in the sole clinical diagnosis with no reference to the prognostic value of the lesion itself. This article reviews the previous classification systems and proposes a new method to classify furcation lesions based on the position of the gingival margin and its relationship with the furcation area (clinically exposed/non-exposed furcation area) providing significant aid for a better understanding of furcation involvements and increases the prognostic value of treatments in the long term.

Extant literature recognizes both family business heterogeneity and the need to identify relevant definitional criteria to distinguish family firms, leading to the emergence of typologies, taxonomies and classification schemes. This paper presents a comprehensive review of existing classifications, which we the compare with the core conceptual elements embedded in 258 family business definitions. Our analyses enables an identification of the characteristics of the entities being classified, and then we proceed to reflect on their usefulness and effectiveness for classifying family firms. Based on the integrated analysis, we then propose some recommendations and future research lines in order to develop a workable classification of family firms.
