The azygos venous system of one Weddell seal (Leptonychotes weddelli) has been described. Both left and right azygos trunks were present with segmental anastomoses between them. The right azygos trunk was the larger and opened into the anterior vena cava; the left azygos trunk terminated in the left costocervical vein. At each segmental level the azygos trunks communicated with collecting sinuses into which drained blood from intercostal spaces and the extradural intravertebral vein. These collecting sinuses were themselves connected to each other by longitudinal anastomoses. The relationship of this system to blood flow during diving is briefly discussed.

Abstract This study was a retrospective investigation of computed tomography (CT) images of an Australian adult hospital population. These images were used to evaluate the spatial relationships of the superior vena cava (SVC) to the midsagittal line, the sternal paracoronal plane, and commonly used landmarks of the sternum. Consistent relationships were found between the long axis of the SVC and both the midsagittal line and sternal paracoronal plane. When the sternal paracoronal plane was used as the plane of reference, the angle of Louis was found to approximate the SVC in 99.5% of cases, and the right 2nd intercostal space approximated the SVC in 94% of cases. Constraints on the use of landmarks are discussed with regard to magnetic guidance systems for catheter tracking.

AbstractHans Kelsen is known both as a legal theorist and as an international lawyer. This article shows that his theory of international law is an integral part of the Kelsenian Pure Theory of Law. Two areas of international law are analysed: first, Kelsen's coercive order paradigm and its relationship to the bellum iustum doctrine; second, the Kelsenian notion of the unity of all law vis-à-vis theories of the relationship of international and municipal law. In a second step, the results of Kelsenian general legal theory of the late period – as interpreted and developed by the present author – are reapplied to selected doctrines of international law. Thus is the coercive order paradigm resolved, the unity of law dissolved, and the UN Charter reinterpreted to show that the concretization of norms as positive international law cannot be unmade by a scholarship usurping the right to make law.

The Relationship

We pump-perfused gastrocnemius-plantaris muscle preparations at constant pressure to study the relationship of muscle blood flow (Q) to muscle oxygen consumption (VO2), venous oxygen tension (PVO2), and venous carbon dioxide tension (PVCO2) during steady-state exercise at different rates. Tests were performed under four experimental conditions produced by altering the perfusate blood-gas status with a membrane lung. The consistency of the relationship of Q to other variables was evaluated by statistical analysis of fitted curves. Not one of the above listed variables had the same relationship with Q in all four of the experimental conditions we tested. However, we did find that a consistent relationship existed among Q, PVO2, and PVCO2 in our data. That relationship is well described by the equation (Q-23).[PVO2 - (0.5.PVCO2) - 3] = 105 (when Q is expressed in ml.100 g-1.min-1 and PVO2 and PVCO2 in mmHg). One interpretation of this result is that both PO2 and PCO2 are important variables in the control of blood flow in skeletal muscle the combined influence of which could account for nearly all of the hyperemia response to steady-state muscle exercise.

The Relationship

Veno-arterial differences of pyruvate and lactate across the myocardium in chloralose-anesthetized dogs were very variable; in any one animal they changed continually with time despite constant blood flow and arterial blood concentrations. There was a systematic tendency of v-a lactate to vary with v-a pyruvate, as expressed in the calculated "Δ excess lactate," which remained nearly constant (or, if blood flow changed, bore a constant ratio to (a-v)O2). No change in Δ excess lactate from control values occurred in nonhypoxic experiments despite marked changes in v-a differences, arterial blood composition, and coronary flow. Cardiac Δ excess lactate became positive in most animals breathing 10% O2 in N2; output of excess lactate was also observed in all those in which moderate muscular exercise was induced. This anaerobic metabolism, or change in the relationship between pyruvate and lactate exchanges, was interpreted as an indication that O2 delivery response was not adequate to meet cardiac tissue requirements during such mild stresses when judged by the standards of adequacy of the basal state.

The relationship of local skin temperature and the onset of sweating to the local cutaneous blood flow was studied in the forearm and calf. The purpose of the investigation was to appraise the possible relation of sweat gland activity to the cutaneous vasodilatation which has been attributed to bradykinin or to intracranial temperatures. The onset of sweating was not marked by any apparently related increases in the rate of cutaneous blood flow. On the contrary, the onset of sweating was followed often by a stabilization or even a decrease in the level of cutaneous blood flow. The relations of the latter to the local skin temperature were complex, particularly in the forearm. There appeared to be additional unidentified influences, possibly vasomotor, operating on the skin vessels during transitional phases in the relation of skin temperature to blood flow.

The speed-torque relationship of the right knee extensor muscle group was investigated in eight untrained subjects (28 +/- 2 yr old). Torque was measured at a specific knee angle during isokinetic concentric or eccentric actions at nine angular velocities (0.17-3.66 rad/s) and during isometric actions. Activation was by "maximal" voluntary effort or by transcutaneous tetanic electrical stimulation that induced an isometric torque equal to 60% (STIM 1) or 45% (STIM 2) of the voluntary isometric value. Torque increased (P less than 0.05) to 1.4 times isometric as the speed of eccentric actions increased to 1.57 rad/s for STIM 1 and STIM 2. Thereafter, increases in eccentric speed did not further increase torque. Torque did not increase (P greater than 0.05) above isometric for voluntary eccentric actions. As the speed of concentric actions increased from 0.00 to 3.66 rad/s, torque decreased (P less than 0.05) more (P less than 0.05) for both STIM 1 and STIM 2 (two-thirds) than for voluntary activation (one-half). As a result of these responses, torque changed three times as much (P less than 0.05) across speeds of concentric and eccentric actions with artificial (3.4-fold) than voluntary (1.1-fold) activation. The results indicate that with artificial activation the normalized speed-torque relationship of the knee extensors in situ is remarkably similar to that of isolated muscle. The relationship for voluntary activation, in contrast, suggests that the ability of the central nervous system to activate the knee extensors during maximal efforts depends on the speed and type of muscle action performed.

La policía comunitaria es una institución de los pueblos indígenas de Guerrero conocida por su capacidad para enfrentar a la delincuencia y generar alternativas de paz social., através de un sistema de justicia y seguridad autónomo. En los últimos años, sin embargo, el sistema comunitario enfrenta el acoso de actores diversos vinculados al incremento de la violencia y la inseguridad que se vive en el país y especialmente en el estado de Guerrero; dicha situación está impactando a la institucionalidad comunitaria, obligando a su redefinición. En este trabajo destaco aspectos centrales de dicha conflictividad así como las respuestas que han dado los comunitarios para hacer frente a las tareas de justicia y seguridad en el marco de nuevos contextos marcados por el despojo neoliberal y la impunidad de actores estatales y no estatales. En este proceso se actualiza la relación de la policía comunitaria con el Estado revelando el peso de la ambigüedad legal y los juegos del poder así como los usos contra-hegemónicos del derecho para disputar la justicia. ---SEGURANÇA E JUSTIÇA SOB ACOSSO EM TEMPOS DE VIOLÊNCIA NEOLIBERAL: respostas do policiamento comunitário de GuerreroO policiamento comunitário é uma instituição dos Povos Indígenas do Guerrero conhecidos por sua capacidade de lidar com o crime e gerar paz social de forma alternativa, usando um sistema próprio de justiça e segurança. Nos últimos anos, no entanto, o sistema da UE enfrenta assédio de várias autoridades envolvidas no aumento da violência e da insegurança que reina no país e, especialmente, no estado de Guerrero; essa situação está afetando as instituições comunitárias, forçando a sua redefinição. Neste artigo, destaco os principais aspectos do conflito e as respostas que têm a comunidade para lidar com as tarefas da justiça e da segurança no contexto dos novos contextos marcados por pilhagem neoliberal e a impunidade de atores estatais e não estatais. Neste processo, a relação de policiamento comunitário com o estado é atualizada, revelando o peso da ambiguidade e dos jogos de poder legais, além de usos contra-hegemônicos do direito de disputar a justiça.Palavras-chave: violência neoliberal; Guerrero; comunidades indígenas---SECURITY AND JUSTICE UNDER HARASSMENT IN TIMES OF NEOLIBERAL VIOLENCE: responses of the Community Police of GuerreroThe community police is an institution of the Indigenous Peoples of Guerrero known for its ability to deal with crime and generate alternatives for social peace, using a system of justice and self security. In recent years, however, the EU system faces harassment from various people responsible for the increase of violence and insecurity within the country and especially in the state in Guerrero; this situation is impacting instituitions in the community, forcing their redefinition. In this paper I highlight key aspects of the conflict and the community's responses to deal with the tasks of justice and security in new contexts marked by neoliberal plunder and impunity of the state (as well as non state figures). In this process, the relationship of the community police with the state is updated revealing the weight of legal ambiguity and power plays, as well as counter-hegemonic use of the right to dispute justice.key words: neoliberal vilence; Guerrero; indigenous people.
