The soil dissipation of the widely used herbicides S-metolachlor(SM)and butachlor(BUT)was evaluated in laboratory microcosms at two environmentally relevant doses(15 and 150μg/g)and for two agricultural soils(crop and paddy).Over 80%of SM and BUT were dissipated within 60 and 30 days,respectively,except in experiments with crop soil at 150μg/*** on compound-specific isotope analysis(CSIA)and observed dissipation,biodegradation was the main process responsible for the observed decrease of SM and BUT in the paddy *** SM,biodegradation dominated over other dissipation processes,with changes of carbon isotope ratios(Δδ13C)of up to 6.5‰after 60 days,and concomitant production of ethane sulfonic acid(ESA)and oxanilic acid(OXA)transformation *** crop soil experiments,biodegradation of SM occurred to a lesser extent than in paddy soil,and sorption was the main driver of apparent BUT *** of the 16 S rRNA gene showed that soil type and duration of herbicide exposure were the main determinants of bacterial community *** contrast,herbicide identity and spiking dose had no significant *** paddy soil experiments,a high(4:1,V/V)ESA to OXA ratio for SM was observed,and phylotypes assigned to anaerobic Clostridiales and sulfur reducers such as Desulfuromonadales and Syntrophobacterales were dominant for both *** soil microcosms,in contrast,were associated with a reverse,low(1:3,V/V)ratio of ESA to OXA for SM,and Alphaproteobacteria,Actinobacteria,and Bacillales dominated regardless of the *** results emphasize the variability in the extent and modes of SM and BUT dissipation in agricultural soils,and in associated changes in bacterial communities.

Between members of a network, interorganizational resilience is favored by effective collaboration and coordination during a crisis. The quality of that collaboration depends on various iterative factors present between these organizations before the occurrence of a *** find that these factors are iterative since collaboration factors follow a mutually reinforcing cycle: collaboration within a crisis management network is conditioned by a general agreement, which is in turn conditioned by the extent to which the institutions coordinate themselves prior to crisis. We evaluated the factors that promote collaboration between public and private organizations that manage the Greater Montréal transportation *** factors are based on adaptive management processes such as mutual agreements, common organizational culture, knowledge and financial resources, levers of power,regulations, and pressure. Crisis management coordination represents the ability to build and assess the effectiveness of common response plans to risks to which they are exposed. We show how these processes vary depending on the links between private and public organizations.

We consider the numerical solution of the free boundary Bernoulli problem by employing level set formulations. Using a perturbation technique, we derive a second order method that leads to a fast iteration solver. The iteration procedure is adapted in order to work in the case of topology changes. Various numerical experiments confirm the efficiency of the derived numerical method.

Most patients with hepatocellular carcinoma （HCC） are not eligible for curative treatment, which is resection or transplantation. Two recent series have emphasized the potential benefits of preoperative arterio-portal embolization prior to surgical resection of such tumours. This preoperative strategy offers a better disease free survival rate and a higher rate of total tumor necrosis. In case of non resectable HCC it is now widely accepted that transarterial chemoembolization （TACE） leads to a better survival when compared to conservative treatment. Thus, the question remains whether combined portal vein embolization （PVE） may enhance the proven efficiency of TACE in patients with unresectable HCC. We herein report the case of a 56-year-old cirrhotic woman with a voluminous HCC unsuitable for surgical resection. Yet, complete turnout necrosis and prolonged survival could be achieved a^er a combined porto-arterial embolization. This case emphasizes the potential synergistic effect of a combined arterio-portal embolization and the hypothetical survival benefit of such a procedure, in selected patients, with HCC not suitable for surgery or local ablative therapy.

Near-infrared spectroscopy(NIRS)has been increasingly utilized in both sport and health sciences to assess various physiological parameters related to exercise performance.1 NIRS methods coupled with the recent development of portable and wearable devices suitable for field-based measurements have revolutionized the study of exercise physiology and the determinants of exercise performance by providing real-time,non-invasive,and spatially localized measurements of tissue oxygenation dynamics.
