Reverse Logistics and Urban Logistics: Making a Link

5684This work is aimed at analyzing potential links between reverse logistics and urban logistics and describing opportunities for collaboration between both areas of research. A description of the current state-of-the-art is provided in order to highlight the main challenges faced by both disciplines. For example, regarding reverse logistics, new recovery options, marketing strategies for recovered products, and legislation issues on the return of products in specific contexts; in regards to urban logistics, long-term planning, stakeholders’ engagement, information management, efficiency, reliability and safety, and new business models are some of such key challenges. Despite the growing interest shown in both logistics areas and their relevance for companies and consumers, reverse logistics and urban logistics are two concepts that are still somewhat unknown and, above all, treated as being relatively separated. However, there exist some aspectswhere the two disciplines converge and thatmay represent opportunities for collaboration, for example, the proper treatment and management of urban waste, and the efficient management of commercial refunds and returns. In addition, other key issues, such as land use, city typology, infrastructures, and stakeholders’ engagement should be further analyzed in order to keep advancing in the description of links between both areas.S

Intraabdominal cystic lymphangioma

Lymphangiomas are benign malformations of lymphatic vessels that are most typically discovered in the pediatric population. The incidence is estimated to be less than 1 in 100,000 individuals [1]. The majority occur in the head and neck. They are less commonly found in the abdominal cavity, varying from <3% to 9.2% [2,3]. Less than 1% of all cases of lymphangiomas occur in the retroperitoneum [4]. Varying clinical presentation can lead to misdiagnosis or delay in treatment. Lymphangioma should be considered when imaging reveals any unexplainable cystic mass. Lymphangioma is usually treated with surgical excision. We present a case report of a 5-year-old boy who presented to our community hospital with progressive increase in abdominal girth and early satiety over several months

Temporal diversity of Taraxacum kok-saghyz plants reveals high rubber yield phenotypes

Cornish K, Kopicky SL, McNulty SK, Amstutz N, Chanon AM, Walker S, Kleinhenz MD, Miller AR, Streeter JG. 2016. Temporal diversity of Taraxacum kok-saghyz plants reveals high rubber yield phenotypes. Biodiversitas 17: 847-856. Taraxacum koksaghyz is a diploid, out-crossing, rubber-producing species under development as an alternative natural rubber crop. About 17,650 seed were obtained from progeny of 20 wild collected plants. New populations of plants were developed in Ohio from a random subsample of these seed, which were then open pollinated. In November 2011, these seed were direct seeded in outdoor shallow raised beds and in high tunnel deep raised beds. Plants were harvested from the outdoor beds from July 2012 to July 2013 to provide temporal phenotypic data as plants developed and overwintered. The high tunnel beds were harvested July 2013, and provided data on 11 individual accessions, and their progeny, and on the effect of winter bed heating. Plants were highly variable. Rubber concentration in root tissue was not directly correlated with root, shoot or plant size. Across all growing conditions and developmental stage, the highest rubber yields per plant were found in plants with large roots combined with a large rosette, and an above average rubber concentration. These parameters appeared to segregate independently, and rubber concentration was heritable. Interbreeding plants selected for large root, large rosette and then high rubber concentration, should rapidly move Taraxacum kok-saghyz towards domestication and commercialization
