Dissolved Organic Matter Features of Three Adjacent Eastern Mediterranean Urbanized Watersheds

Open Journal of Modern Hydrology 2024年第3期14卷 153-173页

Landscape urbanization broadly affects ecosystems in coastal watersheds, but, until now, the influence of nonpoint source urban inputs on dissolved organic matter (DOM) amount, composition, and source is poorly understood. To understand how DOM composition varied with urbanization, fluorescence excitation-emission matrices (EEMs) were determined for urban and non-urban waters from upstream to downstream sites along three adjacent coastal watersheds that flow into the Mediterranean Sea. Two humic DOM fluorescent components (humic-like and fulvic-like peaks) and two proteinic components (tyrosine-like and tryptophane-like peaks) were identified by EEM fluorescence. The results indicated that urbanization had an important influence on DOM concentration and composition, with urban waters having a high degree of DOM variation due to different land uses surrounding each body of water. Urban waters show a higher DOM fluorescence index (FI), the highest fluorescence intensity of protein-like manifested also by BIX values, and a lower value of the humification index (HIX) than non-urban waters which were dominated by allochthonous inputs. In addition, the EEM was compared in dry and wet season where higher DOM amounts and FI appeared in summer due to autochthonous production coming from algae growth compared to allochthonous input from rainfall dominated in wet season. The concentration of DOC increased from upstream to downstream for the three rivers, especially Beirut River. The increase in DOC values was observed in both dry and wet seasons by 39 and 19 times respectively compared to upstream (0.93 - 0.91 mgC/L).

Traditional Games Body and Movement

Journal of Sports Science 2019年第1期7卷 33-37页

In the contemporary age traditional games could be a way to debate and establish a comparison of knowledge carriers to communicate methodologies of good practices adopted and experiences in the use in the protection, conservation and safeguarding of cultural heritage. Different intellectual approaches(1,2,3)defined traditional games are an expression of a country?s cultural background, beliefs and passions as well as reflect the living conditions at the time of their creation. Traditional games seem to have developed similarly through the ages in various parts of Europe even though these were distant from each other. Traditional children’s games could be goal of project to incorporate elements of traditional children’s (outdoor) games in the design of an intelligent, interactive playground.

Surface Water Processes in Coping with Anthropogenic Impact in a Coastal Eastern Mediterranean Region

Open Journal of Modern Hydrology 2024年第2期14卷 69-86页

Rivers are progressively being exposed to increased anthropogenic pollution stresses that are undermining their designated uses and affecting sensitive coastal areas. In this study, three adjacent eastern Mediterranean coastal rivers, Ibrahim, Kaleb and Beirut, were evaluated. Water quality samples were collected in dry and wet seasons from different sampling sites along the river from the source to the outlet which represent a gradient of increased urbanization. The spatiotemporal variability of the physio-chemical properties, heavy metals (Zn, Pb, Cu, Cr, and Cd) and organic matter (DOC) were statistically analyzed to better understand the contribution of point and nonpoint pollution sources. The three rivers (Beirut, Kaleb and Ibrahim) show a similar behavior in calcium and carbonate alkalinity due to the carbonate mineral weathering effect, so they are of calcium bicarbonate type due to their calcareous geological nature. The speciation of anions was affected by temporal variation. Moreover, it is obvious that the Beirut River has a different behavioral characteristic where the water is a sulfate type water with a preferable metal-OM complexation mainly with lead, zinc and copper, whereas Kaleb and Ibrahim are considered to be of a nitrate phosphate type with a preferable metal inorganic complexation, especially copper, that has a consistent behavior in both types of waters. This difference is attributed to the urbanization effect highly impacting the Beirut River.

很多伴有表皮通透屏障功能降低的皮肤病的发生和发展与氧化应激有关。氧化产物的量与皮肤病的严重程度呈正相关性;表皮通透屏障功能的异常程度与皮肤病的严重程度呈正相关性;抗氧化剂在缓解皮肤病的同时,表皮通透屏障功能也得以改善。而增强表皮通透屏障功能可使这些皮肤病得到缓解。此外,皮肤衰老也与氧化应激有关,老年的皮肤的抗氧化能力和表皮通透屏障功能的恢复能力均降低。外用抗氧化剂具有抗皮肤衰老的作用。由此提示,抗氧化或改善表皮通透屏障功能可能有助于防治与其相关的皮肤病。抗氧化剂可用于延缓皮肤衰老。

Evaluation of the Impact of Driver Behavior on Back of Queues Events in Work Zones Using the SHRP2 Naturalistic Driving Study Data

引用

Journal of Transportation Technologies 2024年第2期14卷 179-194页

作者： Shauna Hallmark Guillermo Basulto-elias Nicole Oneyear Omar Smadi Institute for Transportation 2711 S. Loop Drive Suite 4700 Ames Iowa Iowa Division Federal Highway Administration Ames Iowa

The SHRP2 Naturalistic Driving Study was used to evaluate the impact of various work zone and driver characteristics on back of queue safety critical events (crash, near-crash, or conflicts) The model included 43 SCE and 209 “normal” events which were used as controls. The traces included representing 209 unique drivers. A Mixed-Effects Logistic Regression model was developed with probability of a SCE as the response variable and driver and work zone characteristics as predictor variables. The final model indicated glances over 1 second away from the driving task and following closely increased risk of an SCE by 3.8 times and 2.9 times, respectively. Average speed was negatively correlated to crash risk. This is counterintuitive since in most cases, it is expected that higher speeds are related to back of queue crashes. However, most queues form under congested conditions. As a result, vehicles encountering a back of queue would be more likely to be traveling at lower speeds.

Interactive Linear Algebra with Maple V (Textbooks in Mathematical Sciences)

引用

1998年

作者： elias Deeba Ananda Gunawardena

ISBN: (纸本)9780387982403

Interactive Linear Algebra with Maple V is a complete software package for doing linear algebra. It consists of the printed book, and a CD- ROM (with diskettes available on request). The interactive text includes: * A Graphical User Interface which makes it easy to navigate among the components of the text along with animations that explain linear algebra cocepts geometrically. * A collection of interactive lessons with emphasis on experimentation and conjecturing. * A collection of labs which enforces the learning of the concepts. * A collection of applications which stresses modeling and the utility of linear algebra concepts in various disciplines including Computer Science, Population Dynamics, Natural Sciences, Management Sciences, and Engineering. * A unique library of interactive "high-level" functions written in Maple V that can be used in different modes. * A stand alone Testing System. The authors goal has been to implement a philosophy based on the belief that students who study mathematics must enjoy, understand, assimilate, and apply the skills and concepts they study. Students using this text will learn the concepts of linear algebra and their applications in an interactive environment characterized by experimentation, exploration, and discovery learning. Students will play a fundamental and an active role rather than a passive one throughout the learning process.
