菲律宾蛤仔（Ruditapes philippinarum)能量代谢的研究

能量代谢指动物在进行生理活动(如摄食、消化以及动物的活动等)时所消耗能量的总和，一般以动物的呼吸率利排泄率来估计动物的能量代谢。其主要研究内容是闸明生物能量代谢的基木规律以及与环境闪子的关系。菲律宾蛤仔(Ruditapesphil ippmarum)是我国一种重要的养殖贝类，关于其能量代谢的研究却较少，这种状况妨碍了菲律宾蛤仔养殖生态理论的完善和养殖技术的提高。本研究主要对菲律宾蛤仔呼吸率和排泄率的基本规律(能量代谢与体重的关系、能量代谢的昼夜变化)及其与环境因子(饵料浓度、水温、栖息底质环境)的关系进行探讨。研究结果如下：1．不同体重菲律宾蛤仔代谢率小同。实验川菲律宾蛤仔分三种大小：l(干肉重为0．07-0．14g)、ll(干肉重0．27-0．34g)、III(干肉重0．45～0．63g)。温度包括：26℃(八月)、20℃(十月)、1 5℃(十二月)、9℃(一月)。实验共设四个饵料浓度：2．28±0．25，6．454±0．44，10．284±0．82，15．414±1．56mgTPM／L(TPM，总颗粒物)，饵料中POM(颗粒有机物)含量都为4．68±1．64 mg/L。常温下菲律宾蛤仔代谢率随着体重的增大而增大。15℃、20~C、26℃时蛤仔呼吸率与干肉重呈明显的幂函数关系R=aW~b，a值变动范围为0．1076-0．3309；b值变动范围为0．239l～0．8381；蛤仔排泄率与干肉重也呈明显的幂函数关系N=aW~b，a值变动范围为14．213～68．362：b值变动范围为0．3673-1．1 532。9℃(饵料浓度为2．28±0．25mgTPM／L)、20℃(饵料浓度为10．284-0．82mgTPM／L)、26℃(饵料浓度为6．454±0．44mgTPM／L)时不同体重蛤仔氧氮比差异显著，其它情况下不同体重蛤仔氧氮比差异不显著。2．常温下菲律宾蛤仔代谢率受饵料浓度的影响，不同大小蛤仔受饵料浓度的影响程度不同。I组蛤仔呼吸率受饵料浓度的显著影响，II组III组蛤仔呼吸率只在9℃(一月)和26~C(八月)时受饵料浓度的显著影响。26℃时影响最显著，26℃时I组蛤仔在饵料浓度为2．28±0．25，6．45±0．44，l0．28±0．82，15．4l±1．56mgTPM／L时呼吸率分别是O．086，0．146，0．073，0．093(mlO_2／h)；ll组蛤仔在上述浓度饵料中呼吸率分别是0．138，0．214，0．J 26，0．12l(mlO_2／h);III组蛤仔在上述浓度饵料中呼吸率分别是0．129，0．266，0．186，0．192(mlO_2／h)。菲律宾蛤仔呼吸率在饵料浓度为6．45±0．44 mgTPM／L时最高，蛤仔呼吸率在其它饵料浓度时都会降低。菲律宾蛤仔排泄率在饵料浓度为10．28±0．82 mgTPM／L和15．4l士1．56mgTPM／L时显著高于其它浓度组，9℃时这种趋势更明显，9℃时饵料浓度为2．28±0．25，6．454±044，lO．284±0．82，15．41±1．56mgTPM／L中I组蛤仔排泄率分别是4．297，2．874，8．003，6．658(μgNH_3-N／h)；II组蛤仔在上述浓度饵料中排泄率分别是4．011，3．609，10．427，12．732(μgNH_3-N／h)；III组蛤仔在上述浓度饵料中排泄率分别是2．28 l，6．452，10．283，15．417(μgNH_3-N／h)。3．菲律宾蛤仔代谢率受自然温度的显著影Ⅱ向。I组蛤仔在9℃、15℃、20℃、26℃时呼吸率平均为0．057，0．085，0．039，O．099；II组蛤仔在上述四个温度中呼吸率平均为0．08，O．128，0．089，0．149(mlO_2／h)，I组和II组蛤仔在9℃和20~C时呼吸率较低，在26℃时呼吸率最高。III组蛤仔在上述四个温度中呼吸率平均为0．09，O．1 59，O．143，O．193(mlO_2／h)，在9℃时llI组蛤仔呼吸率显著低于其它温度组。温度为9℃、15℃、20℃、26℃时l组蛤仔排泄率平均为5．458，13．169，4．946，11．138(μgNH_3-N／h)：II组蛤仔在上述温度中排泄率平均为7．695，23．578，8．319，23．90l(μgNH_3-N／h)；III组蛤仔在上述温度中排泄率平均为11．738，27．443，15．658，35．407(μgNH_3-N／h)，蛤仔排泄率在15℃和26℃时均高于9℃和20℃。4．摄食状态与饥饿状态菲律宾蛤仔代谢率有明显不同。26℃时蛤仔静止状态呼吸率平均为0．336(m102／g干重．h)，摄食状态呼吸率平均为0．656(ml0_2干重．h)，摄食状态呼吸率比静止状态平均升高了0 32(ml0_2／g干重．h)；26℃时蛤仔静止状态排泄率平均为39．471(μgNH_3-N／g干重．h)，摄食状态排泄率平均为88．08(μgNH_3-N／g干重．h)，摄食状态排泄率比静止状态排泄率平均升高了48．6(μgNH_3-N／g干重．h)。摄食状态代谢率平均是静止状态的2～3倍。根据摄食引起的呼吸率和排泄率升高量得出每氧化产生lμgNH_3-N需0_2量平均为7．05μl。5．人工控制温度对菲律宾蛤仔代谢率有明显影响。不同大小蛤仔受温度的影响程度不同。在温度5℃、10℃、l 5℃、20℃、26℃，I组和II组蛤仔呼吸率都随着温度的升高而升高，在10℃～l5℃和20℃～26℃这二个温度变化范围内呼吸率变化最大，在20℃～26℃时I组蛤仔呼吸率变动范围为O．85～1．04(m10_2／g干重．h)、II组蛤仔变动范围为0．57～0．86(ml0_2／g干重．h)。III组蛤仔呼吸率只在5℃～l0℃时明显增高，变动范围为0．09～0．5l(m10_2／g干重．h)，在10℃～26℃范围内变化不大。I组和II组蛤仔排泄率随着温度的升高而升高，变动幅度较大，在5℃～26℃范围内其排泄率变动范围为10．32～81．53(μgNH_3-N／g干重．h)；而 III组蛤仔排泄率只在5℃～15℃时随着温度的升高而升高，其排泄率变动范围为6．75～23．77(μgNH_3-N/g干重．h)，在15℃～26℃范围内几乎不变。III组蛤仔的适温范围比I组和II组蛤仔广。菲律宾蛤仔在5℃和10℃时氧氮比变化明显，变动范围为2．76～11．44，在15～26℃时变化不大。6．菲律宾蛤仔代谢率有明显的日节律性，呈正弦曲线型变化。蛤仔夜问代谢率明显升高。I组蛤仔夜间呼吸率平均为0．867(m10_2／g干重．h)，白天呼吸率平均为O．504(m10_2／g干重．h)；II组蛤仔夜间呼吸率平均为0．438(m10_2／g干重．h)，白天呼吸率平均为0．36l(m102／g干重．h)；III组蛤仔夜间呼吸率平均为0．409(m10_2／g干重．h)，白天呼吸率平均为0．252(m102／g干重．h)。在22：00-23：00菲律宾蛤仔呼吸率最高。7．底质环境对菲律宾蛤仔的代谢率有明显影响。在饥饿状态下菲律宾蛤仔在泥沙底质中呼吸率平均为l 406(m10_2／g干重h)，在无泥沙环境中呼吸率平均为O．963(ml0_2／g干重．h)；摄食状态下菲律宾蛤仔在泥沙底质中呼吸率平均为1．59l(m102／g干重．h)，在无泥沙环境中呼吸率平均为1．115(m10_2／g干重．h)。在饥饿状态下菲律宾蛤仔在泥沙底质中排泄率平均为78．934(μgNH_3-N／g 干重．h)，在无泥沙环境巾排泄率平均为45．043(μgNH_3-N／g干重．h)；摄食状态下菲律宾蛤仔在泥沙底质中排泄率平均为87．12l(μgNH_3-N／g干重．h)，在无泥沙底质中排泄率平均为58．354(μgNH_3-N／g干重．h)。蛤仔在泥沙环境中呼吸率和排泄率都明显升高。

Terlipressin as an adjunct vasopressor in refractory hypotension after tricyclic antidepressant intoxication

AIM OF STUDY: To report the management of cardiovascular failure refractory to standard catecholamine therapy with terlipressin in a patient with tricyclic antidepressant (TCA) intoxication. CASE REPORT: A 41-year-old woman, with suicidal ingestion of 11.25 g amitriptyline and 1500 mg diclofenac, was admitted to the emergency department. After 30 min in ventricular fibrillation, with ongoing CPR, she regained a potentially perfusing rhythm, but with hypotension refractory to standard catecholamine therapy with adrenaline, 2 microg/kg/min (norepinephrine); adrenaline, 1 microg/kg/min (epinephrine) until 55 min after admission. An injection of 1 mg terlipressin restored mean arterial blood pressure >65 mmHg within 10 min. Ten hours after admission to the intensive care unit, catecholamine support could be withdrawn because of a stable haemodynamic state. Within 7 days, all organ function recovered, and the patient regained full neurological function. CONCLUSIONS: Successful management of cardiovascular failure with terlipressin after TCA intoxication refractory to catecholamines suggests a potential role for terlipressin as an adjunct vasopressor in severely hypotensive patients.

Chairship system and decision making by consensus in international agreements : the case of ASEAN

How are different positions reconciled under decision making by consensus in international agreements? This article aims to answer this question. Consensus rule provides each participant a veto, which risks resulting in non-agreement. Taking ASEAN as a case study of international organizations that have adopted consensus rule as the main decision-making procedure, this article presents the chairship system as an analytical scheme to examine how different positions are or are not reconciled under consensus rule. The system is based on conventional knowledge regarding the chair in international conference, which can be defined as an institution where the role of the chair is taken by one member state in an international organization and plays a role in agenda-setting. The agenda-setting power given to the chair varies across organizations. This article assumes that the chair in ASEAN is given a relatively strong agenda-setting power to enable the chair to reach agreements and bias such agreements in its own favor.

Resolución (86)3 del Consejo de Europa sobre la cooperación cultural europea :adoptada por el Comité de Ministros el 23 de abril de 1986 en su 78ª Sesión.

Se recoge el documento de resolución adoptado por el Comité de Ministros en el que se afirma que: la cooperación cultural es uno de los fundamentos de la acción del Consejo de Europa; constituye un marco particularmente cualificado para la promoción de la identidad europea de la cual la diversidad cultural es un componente importante; reconoce la interacción entre la cultura y la educación; considera que la definición de las orientaciones políticas de la cooperación cultural pertenecen al Comité de Ministros; desea que los trabajos de las Conferencias de ministros europeos responsables de la cultura y de la educación se inscriban más estrechamente en el marco de las actividades del Consejo de Europa; subraya la importancia de reforzar el impacto de la acción cultural del Consejo de Europa en los estados miembros; debe disponer de recursos correspondientes a su importancia; estima que la cooperación cultural constituye uno de los dominios de acción que se prestan mejor a poner en marcha la Resolución (85)5 sobre la cooperación entre el Consejo de Europa y la Comunidad Europea; y recuerda la Resolución (85)6 sobre la identidad cultural europea. Por último, pide a los Delegados examinar las posibilidades de una colaboración en el dominio cultural con las regiones fuera de Europa pero sin olvidar que la prioridad debe ser acordada a la cooperación entre países europeos.

Characteristics of airborne ultrafine and coarse particles during the Australian dust storm of 23 September 2009

Particle number concentrations and size distributions, visibility and particulate mass concentrations and weather parameters were monitored in Brisbane, Australia, on 23 September 2009, during the passage of a dust storm that originated 1400 km away in the dry continental interior. The dust concentration peaked at about mid-day when the hourly average PM2.5 and PM10 values reached 814 and 6460 µg m-3, respectively, with a sharp drop in atmospheric visibility. A linear regression analysis showed a good correlation between the coefficient of light scattering by particles (Bsp) and both PM10 and PM2.5. The particle number in the size range 0.5-20 µm exhibited a lognormal size distribution with modal and geometrical mean diameters of 1.6 and 1.9 µm, respectively. The modal mass was around 10 µm with less than 10% of the mass carried by particles smaller than 2.5 µm. The PM10 fraction accounted for about 68% of the total mass. By mid-day, as the dust began to increase sharply, the ultrafine particle number concentration fell from about 6x103 cm-3 to 3x103 cm-3 and then continued to decrease to less than 1x103 cm-3 by 14h, showing a power-law decrease with Bsp with an R2 value of 0.77 (p<0.01). Ultrafine particle size distributions also showed a significant decrease in number during the dust storm. This is the first scientific study of particle size distributions in an Australian dust storm.

Legal Profession Act 2007 s 319 - Whether costs agreement made after trial valid and enforceable - whether agreement had retrospective operation

The decision in QCOAL Pty Ltd v Cliffs Australia Coal Pty Ltd [2010] QSC 479 involved an examination of a number of issues relating to the assessment of costs under the Legal Profession Act 2007 (Qld). The decision highlights a range of issues which, in slightly different circumstances, may have deprived the successful party of the right to recover costs by reference to the costs agreement.

APQL : a process-model query language

As business process management technology matures, organisations acquire more and more business process models. The management of the resulting collections of process models poses real challenges. One of these challenges concerns model retrieval where support should be provided for the formulation and efficient execution of business process model queries. As queries based on only structural information cannot deal with all querying requirements in practice, there should be support for queries that require knowledge of process model semantics. In this paper we formally define a process model query language that is based on semantic relationships between tasks in process models and is independent of any particular process modelling notation.
