EFFECTS OF ELECTRICAL STIMULATION OF THE NEUROHYPOPHYSIS ON LABOUR IN THE RAT (1975)

Labour was studied in 69 primiparous and multiparous rats by continuous observation and by the recording of intra-uterine activity. The effect of electrical stimulation of the neurohypophysis with stimulation parameters selected to create a pulsatile release of oxytocin was investigated. Stimulation was applied to the neurohypophysis through chronically implanted electrodes every 5 min, in 45 min sessions, from noon on Day 21 of gestation and at 3 h intervals thereafter. Electrical stimulation successfully promoted (or induced) the onset and facilitated the course of labour. Stimulation at 12.00 h on Day 21, or at a subsequent stimulation session 3, 6, 9 or more hours later, promoted an immediate increase in the frequency and amplitude of uterine contractions. Overt signs of abdominal straining followed within 5-30 min and the first pup was delivered shortly thereafter. These 'induced' deliveries were almost identical to those displayed by control rats; labour continued to completion despite the termination of the stimulation session after 45 min. By contrast, one third of the stimulated animals displayed an interrupted pattern of labour in which events virtually ceased for 30-60 min when stimulation was terminated. Stimulation, however, only advanced labour by 1-2 h in relation to control animals; this was not statistically significant. Stimulation accelerated the delivery of the first 5 pups in each litter. In both stimulated and control animals, the birth intervals declined over these first few deliveries to reach the lowest values of 5-6 min throughout the remainder of labour. The most common litter size was 12 pups. The distribution of labour on Day 21 and 22 was bimodal. Seventy per cent of the animals gave birth between 12.00 and 18.00 h on Day 21, a few gave birth during the following night and the remainder formed a second peak on Day 22. All litters of less than 6 pups were born during this later period. The implications of these results in the context of spontaneous labour are discussed. We conclude that endogenous oxytocin (with perhaps other neurohypophysial hormones) released in pulses of 1-3 mu. every 5 min can promote a pattern of labour on Day 21 of gestation that is almost indistinguishable from that which occurs naturally.
ZIF-8 crystal coatings on a polyimide substrate and their catalytic behaviours for the Knoevenagel reaction (2012)

ZIF-8 crystal coatings were prepared by direct growth on different flexible polyimide substrates including a thin membrane and electrospun nanofiber mat. In SEM pictures, the ZIF-8 crystals exhibit a rhombic dodecahedron morphology. Owing to the flexible polyimide substrate, the MOF-polymer film may be moderately bent or easily tailored when not destroyed. The ZIF-8 coatings can be activated at high temperature owing to the excellent thermal resistance and low coefficient of thermal expansion of the polyimide. Furthermore, this material may be used as an efficient heterogeneous catalyst for the Knoevenagel reaction and can be easily recovered. The ZIF-8 coatings and 2-methylimidazole show similar catalytic behaviour as a weak base.

Consultant expertise (1987)

Abstract: Experts typically solve problems in narrow domains (e.g. the diagnosis of congenital heart diseases). Consultants, however, have expertise that is based on an ability to apply expertise across domains. Such expertise is exhibited in most fields. In this paper we report an investigation of consultant expertise in statistical experimental design. Our analysis reveals that consultants are successful because of their ability to 1) formulate the client's problem in abstract terms, 2) refine and modify this formulation through interaction with the client, and 3) incorporate the client's domain knowledge into an effective problem solution.

Anti-lipid peroxidation and protection of ginsenosides against cerebral ischemia-reperfusion injuries in rats. (1990)

The correlation between protective effect of ginsenosides Rb + R0 and brain endogenously-derived prostacyclin synthesis, thromboxane A2 formation and lipid peroxidation were estimated in rats. Ginsenosides Rb + R0 100 mg/kg iv 30 min before 4-vessel occlusion elevated 6-keto-PGF1 alpha level, declined thromboxane B2 and brain edema formation, reduced the rise of lipid peroxides and suppressed the reduction in both creatine phosphokinase (CK) and superoxide dismutase (SOD) activities in brain tissue after 40-min ischemia followed by 1-h reperfusion. Furthermore, these improvements were partially abolished by pretreating with iv indomethacin. It is concluded that ginsenosides possess protective effect on cerebral ischemia-reperfusion injury of rats and ginsenosides Rb + R0 are the active principles. The underlying mechanism of protection is ascribed partially or mainly to the facilitated synthesis and release of prostacyclin, reduced formation of thromboxane A2 and inhibited generation of free radicals and subsequent lipid peroxidation.
Methods to Solve Discrete Logarithm Problem for Ephemeral Keys (2009)

The present study investigates the difficulty of solving the mathematical problem, namely DLP (Discrete Logarithm Problem) for ephemeral keys. DLP is the basis for many public key cryptosystems. The ephemeral keys are used in such systems to ensure the security. The DLP defined on a prime field Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</sub> * of random prime is considered in the present study. The most effective method to solve the DLP is the Index Calculus Method. In the present study, an efficient way of computing the DLP for ephemeral key by using a new variant of ICM when the factors of p-1 are known and small is proposed. The ICM has two steps, such as a pre-computation and an individual logarithm computation. The pre-computation step is to compute the logarithms of a subset of a group and the individual logarithm step is to find the DLP using the pre-computed logarithms. Since the ephemeral keys are dynamic and changes for every session, once the logarithms of a subset of a group is known, the DLP for the ephemeral key can be obtained using the individual logarithm step. Therefore, an efficient way of solving the individual logarithm step based on the newly proposed pre-computation method is presented and the performance is analyzed on a comprehensive set of experiments. The ephemeral keys are also solved by using other methods, which are efficient on random primes, such as Pohlig-Hellman, Var-Oorschot method and traditional individual logarithm step. The results are compared with the newly proposed individual logarithm step of ICM. Also, the DLP of ephemeral keys used in a popular password key exchange protocol known as Chang and Chang are computed and reported.
Community organization (1990)

Community Organization in Asia draws on the work of the Asian Committee for People's Organization to set out some lessons about how a community organizer should work. It describes the Asian Committee for People's Organization and its philosophy, and identifies the different steps in the process whereby a community organizer comes to work in low-income settlements with organizations formed by their inhabitants. The paper includes a summary of the Tagisan Statement produced by representatives from over 85 organizing groups in the Philippines in 1985. A final section draws on the author's 20 years working with community organizations to consider their strengths and the difficulties they face.

Basicity of Acetamidine. Experimental and Theoretical Study (1996)

The gas-phase proton affinity of acetamidine has been determined using FT-ICR spectrometry to be 230.1 kcal/mol (962.7 kJ/mol). High-level ab initio calculations were performed to investigate whether acetamidine is planar in its equilibrium conformation. The effect of solvation on both its structure and its basicity was analyzed using the self-consistent reaction field theory. The two stable isomers 1a and 1b are almost degenerate but separated by a significantly high isomerization barrier. Much higher is the tautomerization barrier between acetamidine 1a and 1,1-diaminoethylene (2). The amino rotational barrier is of the same order of magnitude as those of typically Y-conjugated systems such as guanidine. Most unexpected, this barrier is twice as large for protonated acetamide as for protonated guanidine. This is consistent with the fact that the intrinsic basicity of acetamidine is only 3.0 kcal/mol lower than that of guanidine. In solution, the situation is similar, and acetamidine is slightly less basic than guanidine. Similarly, 1,1-diaminoethylene is predicted to be a very strong carbon base in the gas phase with a proton affinity 6 kcal/mol greater than that of guanidine.

Tinnitus: questions to reveal the cause, answers to provide relief. (2004)

T innitus—the perception of sound that does not have an external source—can be constant or intermittent and perceived as ringing, buzzing, hissing, sizzling, roaring, chirping, or other sounds. Acute tinnitus, which can last days or weeks, may be caused by ear infection, medications, head or neck injury, excessive sound exposure, earwax, and changes in blood pressure or metabolism. With appropriate evaluation, such underlying conditions usually can be identified and treated, often with resultant resolution of tinnitus. Chronic tinnitus (persistence for 6 months or more) can also result from these conditions and is more likely to occur in people who have hearing loss. (See Prevalence of tinnitus.) Even though a true “cure” for most cases of chronic tinnitus is not available, patients can obtain relief from the symptom with assistance from clinicians who are familiar with tinnitus management strategies.
DPCA Detection of Moving Targets in Airborne Passive Radar (2012)

A new approach to the passive coherent location (PCL) signal processing technique dedicated for use on mobile radar platforms is presented. The main goal of the research conducted was to present different aspects of an efficient space-time ground moving target indication (GMTI) algorithm for PCL radar mounted to airborne platforms. The algorithm described, based on displacement phase center antenna (DPCA), has been successfully tested with simulated and real-life data collected with an airborne passive radar demonstrator (PaRaDe).
Picosecond switching dynamics of a bistable-wavelength-latch two-segment distributed feedback laser (1990)

The bistable-wavelength-latch operation of a two-segment distributed-feedback laser was observed and characterized. Short electrical trigger pulses were used to demonstrate mode power switching in less than 200 ps with only 450-ps delay between set and reset pulses. Spectrally resolved measurements show transient spectral broadening during the bistable wavelength switching. Fast laser wavelength switching is important for wavelength-division-multiplex photonic switching systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Camilla the go-between: the politics of gender in a Roman household (1559) (1989)

A partir des témoignages devant un magistrat de la cour papale, instruisant un cas de proxénétisme, nous pouvons dénouer les fils d'une intrigue amoureuse et domestique. Cette affaire oppose un mari brutal et jaloux à la frêle coalition d'une épouse adultère et de sa servante qui connive avec elle. Une lecture serreé des textes – les évènements domestiques et les termes employés pour les décrire – permet de reconstituer les stratégies des trois antagonistes. De l'interaction des intérêts personnels et des responsabilités de chacun d'eux, de l'éthique sociale et des structures légates naît une tactique de ce ménage, qui, à une moindre échelle, copie les moeurs politiques de la société en général.
Exploration of steering feel (2015)

In this thesis, the concept of steering feel, as experienced by the driver, is explored. First a literature review is conducted to highlight previous work on this topic. From this review, the Norman on-centre test and steering wheel torque are identified as important concepts, and are chosen to form the base of this thesis. Following this, steering system and tyre construction are described, and a single-track mathematical model of a car and its tyres is illustrated. Those models are then implemented in Simulink and are used to simulate the Norman on-centre test and explore the effects of vehicle mass, steering ratio and power-steering servo curves on steering wheel torque. Without power steering, vehicle mass and steering ratio are identified as having the largest effect on the steering torque. With power steering added to the model, it becomes the dominating factor in shaping the steering wheel torque, and it is concluded that future research in this area is likely to focus on power-steering and steer-by-wire effects.
Advanced applications for materials implanted within the human body (1987)

Biomaterials are materials that are used in medical devices that are intended to interact with biological systems. These medical devices include the now common hip replacements and prosthetic heart valves, and the less common neurological prostheses and implantable drug delivery systems. Biomaterials include the traditional stainless steel, titanium, polyethylene, and polymethyl methacrylate and the more biologically sophisticated calcium hydroxyapatite, surface modified polymers, and glass ceramics. In this paper, some of the principles that are involved in the selection and use of these materials in present and future medical devices are discussed.MST/663
Possible Effect of Race on Tricyclic Plasma Levels (1978)

To the Editor.— Ziegler and Biggs (238:2167-2169, 1977) report on the effect of age, sex, smoking, and race on plasma levels of amitriptyline hydrochloride and nortriptyline hydrochloride. It seems to us that they made an error in the logic of their data analysis. The patients were not assigned to a fixed dose. Despite this, the authors wished to examine the effect of the four variables on plasma level. To correct for the different doses, they changed the actual plasma levels so that each patient's plasma level was based on 1 mg/kg oral dose. Presumably, they divided the actual plasma level by the 1 mg/kg dose for each patient. Nowhere do they justify this technique. To be valid one would need to show that plasma levels correlate to a high degree and in a linear fashion to the 1 mg/kg dose. The authors themselves point out that Hammer et al 1

Nerve growth factor receptor molecules in rat brain. (1986)

We have developed a method to immunoprecipitate rat nerve growth factor (NGF) receptor proteins and have applied the method to detect NGF receptor molecules in the rat brain. Crosslinking 125I-labeled NGF to either PC12 cells or cultured rat sympathetic neurons yielded two radiolabeled molecules (90 kDa and 220 kDa) that were immunoprecipitated by monoclonal antibody 192-IgG. Further, 192-IgG precipitated two radiolabeled proteins, with the expected sizes (80 kDa and 210 kDa) of noncrosslinked NGF receptor components, from among numerous surface-iodinated PC12 cell proteins. These results demonstrate the specific immunoprecipitation of NGF receptor molecules by 192-IgG. We applied the 125I-NGF crosslinking and 192-IgG-mediated immunoprecipitation procedures to plasma membrane preparations of the following areas of rat brain: medial septum, cerebellum, brainstem, hippocampus, cerebral cortex, thalamus, and olfactory bulb. NGF receptor molecules of the same molecular masses as the peripheral receptor components were consistently detected in all of these regions and in preparations from whole brains. Removal of the peripheral sympathetic innervation of the brain did not eliminate these NGF receptor proteins, indicating that the receptor is endogenous to central nervous system tissues. We also observed retrograde transport of 125I-labeled 192-IgG from the parietal cortex to the nucleus basalis and from the hippocampus to the nucleus of the diagonal band of Broca and the medial septal nucleus. These findings demonstrate the presence in brain of NGF receptor molecules indistinguishable from those of the peripheral nervous system.
