Aquarium Portal Technique for PASTA Lesion Repair
The simultaneous arthroscopic exposure of the subacromial and intra-articular space of the shoulder is challenging in the presence of only partial-thickness rotator cuff tears. We present our experience and method of entering the joint through the opened rotator cuff interval from an anterosuperior portal between the coracoid process and anterior acromion. With moderate (approximately 30°) abdu...
متن کاملThe EcoSystem Aquarium Revisited
One way I judge how an article has been received is by how many letters or phone calls I get about it. Judging by the number of requests for more information on the Ecosystem Aquarium Filtration method, developed by Leng Sy, that I have received since writing articles in both Aquarium Fish Magazine (November 1997) and SeaScope (Fall 1997), I really struck a nerve. There are probably a number of...
متن کاملEvaluation of aquarium antibiotic formulations.
The antibacterial activity of eight products marketed for the therapy and prophylaxis of diseases of ornamental fishes was tested. The products contained erythromycin, neomycin, a nitrofuran, penicillin, sulfa compounds, streptomycin, or tetracycline. When used at the concentration recommended by the manufacturer, the products failed to inhibit the growth of bacterial species known to be potent...

tion of the object wavefunction in amplitude and phase from the measured data. However, before we can make a measurement of a quantum state we have to prepare that state. In the case of the caesium atom this job was done by the first object pulse. Can we prepare any desired state, that is, a target state? This is an issue that arises in many disciplines — ranging from physical chemistry, throug...
متن کاملAquarium Nitrification Revisited: Thaumarchaeota Are the Dominant Ammonia Oxidizers in Freshwater Aquarium Biofilters
Ammonia-oxidizing archaea (AOA) outnumber ammonia-oxidizing bacteria (AOB) in many terrestrial and aquatic environments. Although nitrification is the primary function of aquarium biofilters, very few studies have investigated the microorganisms responsible for this process in aquaria. This study used quantitative real-time PCR (qPCR) to quantify the ammonia monooxygenase (amoA) and 16S rRNA ge...
