The cryptic habits of subterranean termites restricts detailed analysis of their foraging patterns in situ, but the process is evidently dominated by tunnel constructions connecting the nest with woody resources discovered within the territory of each colony. In this study, tunnel formation and orientation were studied experimentally in the termite Reticulitermes grassei （Clement）, using 2-dimensional laboratory foraging arenas con- taining fine sand as the substratum. The building of exploratory tunnels over a 10-day period and the geometry of the resulting network are described. Fractal analysis showed that tunnel geometry had a fractal dimension, regardless of the total length tunnelled whether foragers encountered the food source or not. The bulk density of the sand in the arenas affected the distances tunnelled, with higher density reducing construction, but did not affect tunnel geometry. Tunnels were not discernibly orientated with respect to the positioning of the food source, even in a situation where termites had failed to find the food source at a distance of less than 50 mm, suggesting that volatiles from wood are not attractants.

BACKGROUND This was an observational, descriptive, and retrospective study from 2011 to 2020 from the Department of Informatics of the Brazilian Healthcare System *** To describe the intestinal complications(IC) of patients with ulcerative colitis(UC) who started conventional therapies in Brazil’s public Healthcare *** Patients ≥ 18 years of age who had at least one claim related to UC 10th revision of the International Statistical Classification of Diseases and Related Health Problems(ICD-10) code and at least 2 claims for conventional therapies were included. IC was defined as at least one claim of: UC-related hospitalization, procedures code for rectum or intestinal surgeries, and/or associated disease defined by ICD-10 codes(malignant neoplasia of colon, stenosis, hemorrhage, ulcer and other rectum or anus disease, megacolon, functional diarrhea volvulus, intussusception and erythema nodosum). Descriptive statistics, annual incidence, and incidence rate(IR) [per 100 patient-years(PY)] over the available follow-up period were *** In total, 41229 UC patients were included(median age, 48 years;65% women) and the median(interquartile range) follow-up period was 3.3(1.8-5.3) years. Conventional therapy used during follow-up period included: mesalazine(87%), sulfasalazine(15%), azathioprine(16%) or methotrexate(1%) with a median duration of 1.9(0.8-4.0) years. Overall IR of IC was 3.2 cases per 100 PY. Among the IC claims, 54% were related to associated diseases, 20% to procedures and 26% to hospitalizations. The overall annual incidence of IC was 2.9%, 2.6% and 2.5% in the first, second and third year after the first claim for therapy(index date), respectively. Over the first 3 years, the annual IR of UC-related hospitalizations ranged from 0.8% to 1.1%;associated diseases from 0.9% to 1.2%-in which anus or rectum disease, and malignant neoplasia of colon were the most frequently reported;and procedure events from 0.6% to 0.7%, bein

Bionic Photovoltaic Panels Bio-Inspired by Green Leaves

引用

Journal of Bionic Engineering 2010年第3期7卷 284-293页

作者： MatthiasZhr Dennis Friedrich tania Y.Kloth Gerhard Goldmann Helmut Tributsch Technische Fachhochschule Berlin Helmholtz-Zentrum

In strong solar light, silicon solar panels can heat up by 70℃ and, thereby, loose approximately one third of their efficiencyfor electricity generation. Leaf structures of plants on the other hand, have developed a series of technological adaptations,which allow them to limit their temperature to 40-45℃ in full sunlight, even if water evaporation is suppressed. This is accomplishedby several strategies such as limitation of leaf size, optimization of aerodynamics in wind, limitation of absorbedsolar energy only to the useful fraction of radiation and by efficient thermal emission. Optical and infrared thermographicmeasurements under a solar simulator and in a streaming channel were used to investigate the corresponding properties of leavesand to identify suitable bionic model systems. Experiments started with the serrated structure of ordinary green leaves distributedover typical twig structures and finally identified the Australian palm tree Licuala ramsayi as a more useful bionic model. Itcombines a large area for solar energy harvesting with optimized aerodynamic properties for cooling and is able to restructureitself as a protection against strong winds. The bionic models, which were constructed and built, are analyzed and discussed.

Barriers and facilitators of implementing child injury surveillance system

引用

Chinese Journal of Traumatology 2019年第4期22卷 228-232页

作者： tania Azadi Davoud Khorasani-Zavareh Farahnaz Sadoughi School of Health Management and Information Sciences Iran University of Medical Sciences Tehran Iran Safety Promotion and Injury Prevention Research Center Health in Disaster and Emergency Department School of Health Safety and Environment Shahid Beheshti University of Medical Sciences Tehran Iran Health Management and Economics Research Center School of Health Management and Information Sciences Iran University of Medical Sciences Tehran Iran

Purpose: Child injuries are a global public health problem and injury surveillance systems (ISS) can be beneficial by providing timely data. However, ISS implementation has challenges. Opinions of stakeholders of ISS implementation barriers and facilitators are a good source to understand this phenomenon. The aim of this study is to investigate barriers and facilitators of implementing ISS in Iran. Methods: This is a qualitative study. Data were gathered through interviews with 14 experts in the field of child injury and prevention from Iranian Ministry of Health and Medical Education (MOHME), medical univers让ies, pediatrics hospitals, general hospitals and health houses during January 2017 to September 2017. Data collection and analysis con tinued until data saturation. Data were analyzed using con tent analysis through identifying meaning units. Results: Barriers were classified in three main categories and nine subcategories including management barriers (including performance, coordination and cooperation, supervision and attitude), weakness in data capture and usage (including data collection, data recording and data dissemination) and resource limitation (including human and financial resources). Facilitators identified in three areas of policy making (including empowerment and attitude), management (including organization, function and cooperation and coordination) and data recording and usage (including data collection/distTibution and data recording). Conclusion: The most important barrier is lack of national policy in child injury prevention. The most important facil让ator is improving MOHME function through passing supportive regulations. Effective data usage and dissemination of information to those requiring data for policy making can help reduce child injuries. Coalition of stakeholders helps overcome existing barriers.
