Abstract: An apparatus for controlling airborne pollution comprises a leeward wall located near a polluted region, and a windward wall located between the leeward wall and the polluted region. The leeward wall and the windward wall are spaced apart so as to define an airflow passageway therebetween. The windward wall extends upwardly to a first wall height. The leeward wall includes an upper portion extending above the first wall height.  The upper portion is adapted to direct airflow downward through the airflow passageway towards at least one opening located below the first wall height for exhausting the airflow from the airflow passageway.

Abstract: A blood pressure monitor may be calibrated by connecting its pressure sensor to a disposable, sealed, single use canister containing gas at a known pressure. The monitor is arranged to compare the known pressure with the signal from the sensor to check or adjust its calibration.  Several canisters containing gas at different known pressures may be used sequentially to calibrate the monitor across a range of pressures. The monitor may include shock and temperature sensing means, and may display a blood pressure reading or transmit it to a remote location together with an indication of the calibration status of the monitor. The system enables simple and reliable recalibration of a blood pressure monitor in the user's home and provides greater confidence in remotely monitored blood pressure readings.

IPC: H05B44/00

Abstract: An integrated drive circuit for multi-segment electroluminescent displays is provided. During a charging phase, the electroluminescent segments are charged by a common charge circuit, and partially discharged using separate discharge circuits associated with individual electroluminescent segments. A controller provides essentially independent control over the respective discharge circuits so, by the end of the charging phase, the EL segments can be charged to correspondingly different final voltages. Then during a discharging phase following the charging phase, the electroluminescent segments are completely discharged, thereby emitting an intensity of light that varies roughly in proportion to the final accumulated voltage. The controller can be pre-programmed with a spatial-temporal light pattern so that, using the disclosed integrated drive circuit, the electroluminescent display can be operated to generate rudimentary animations.

Title: Mustard oil as an antimalarial treatment
Inventor: MACALPINE JESSIE
IPC: A61K36/31
Filed: 2013-05-07
Abstract: Half of the global population is susceptible to malarial infection, with over one million annual deaths occurring as a result of the disease. Plasmodium, the causative agent of malaria, contains a vital plastid-organelle homologous to the chloroplasts of plants, known as the apicoplast. It was determined in previous studies that allyl isothiocyanate (AITC) is able to inhibit plant growth in a variety of species through effects on photosynthetic function. The purpose of this experiment was thus to examine the antimalarial properties of mustard oil, a natural form of AITC used as cooking oil in developing countries.  A one-step fluorescence assay used for antimalarial drug screening was employed throughout the experiment; resulting in the discovery that a 2µg/mL solution of pure mustard oil is able to significantly reduce Plasmodium falciparum infection in human red blood cells. Results of an MTT assay and light microscopy indicate that mustard oil exhibits equivalent mammalian toxicity to the common antimalarial drug Doxycycline. AITC is currently sold as an antibiotic, where clinical studies indicate that oral administration results in 90% absorption and rapid urinary drug recovery.  With no organic solvent necessary, pure mustard oil (purchased from a local grocery) inhibits over 94%  of parasite growth. Thus, the necessary dose of 10mg has potential to be taken orally, a treatment costing one million times less than the next leading antimalarial. Mustard oil production already occurs in malaria-endemic regions;  including Brazil and India, making this cooking oil an inexpensive, accessible and effective alternative to current treatments.

Chaque serveur esclave de niveau supérieur peut gérer des permissions d'accès pour un ou plusieurs serveurs esclaves de niveau inférieur au(x) système(s) utilisateur(s) non intelligent(s). Un serveur maître ou, si l'accès lui est permis, un serveur esclave, crée une fenêtre dans un dispositif d'affichage du système utilisateur non intelligent, et peut permettre un accès à la fenêtre à n'importe quel serveur esclave de niveau inférieur pour envoyer des pixels afin de remplir cette fenêtre. Les pixels peuvent être la sortie graphique d'une application, telle qu'un navigateur ou un tableur, ou les pixels peuvent être de la vidéo (soit en direct soit lue dans un disque dur). Dans d'autres applications des serveurs, le système serveur peut commander une sortie sur des composants du système utilisateur, et recevoir une entrée en provenance de composants et de périphériques du système utilisateur, le tout par des communications sur le réseau. Un accès aux systèmes utilisateurs non intelligents respectifs est dicté par le serveur maître et chaque serveur esclave de niveau supérieur de l'ensemble hiérarchique de serveurs. Des données représentant une entrée de composants et de périphériques sont multiplexées et communiquées sur le réseau par le système utilisateur, et des données représentant une sortie de composants du système utilisateur sont reçues par le système utilisateur sur le réseau et démultiplexées et fournies au composant en vue d'une sortie sur le système utilisateur.
