To start off, there are no problems with water quality. I have experience with fish and the nitrogen cycle and have tested parameters every day and found no problems. This particular betta has been living alone in a 5-gallon cycled tank for almost a year now. This is the first time I have had a sick fish.

My betta is experiencing the following symptoms:

1.) fins have rapidly deteriorated (within a week, his fins are less than half their original size)

2.) color loss (was a vibrant blue, but now turning pale and grayish)

3.) rapid weight loss except in area of pectoral fins, which has maintained its original size

4.) eyes bulging out -- Fish is unable to see well enough to eat food. He will try pouncing on the food but completely miss by a half inch.

5.) lethargy -- he hardly moves at all when before he was a very active fish

I have tried treating with medications: first with kanaplex, then with API fungus cure. He looked a little better after the first dose of kanaplex, but then got worse again. I did not see any change in his condition with the API fungus cure.

Any ideas on what this could be and/or what I can do to treat him?

She claims that when they pulled the carpets back, the smell of cat urine was so bad that they had to rep them. I don't mind paying for the carpet if my cat did indeed per on it, but I also want to make sure that my landlord isn't just taking advantage of me. Is it plausible that my cat would only per when I'm not home and that I would never notice a smell or stain when I returned? Again, I have never seen my cat not use the litterbox, and I have never seen or smelled pee on the carpet.

I'm having an event in a small auditorium (200 person capacity) and would like to play music from my laptop. What kind of speakers should I get that will be loud enough for this type of venue and connect to a laptop?

I calculated the osmotic pressure between the extracellular fluid and cytosol to be:

RTΔc=(0.0821)(310)(0.05) = 1.27atm

where 0.05=the osmolarity difference between the inside and outside of the cell

Is my reasoning correct that this fluid is not isotonic because this osmotic pressure value is not 0?

I understand how a PLL works that compares the frequency of the incoming signal to a reference frequency and then adjusts the incoming signal to match the reference frequency. However, I am confused about how to use a PLL to multiply the frequency of the incoming signal by the frequency of the reference signal. Could someone please explain this?

I have a rectified AC waveform, and I want to convert it to DC. Is it as simple as dividing the AC waveform by 0.707, or am I misunderstanding something?

The day after my interview, I received an email from the department to which I applied. It said: "We accept your job application. HR will contact you as soon as possible". It has been almost a week, and I haven't heard back yet. How long should I wait before I follow up?

Ich danke Ihnen für Ihre Hilfe!

Meine Name ist ___________ _________, und ich bin in meinem siebten Semester im Biomedizintechnik an der Universität von ____________ (in den USA). Ich bin in meiner Universitäts International Praktikum Programm und ich interessiere mich für mögliche Chancen zu ein Technische Praktikum bei Ihnen machen. Ich habe viel Interesse in der Arbeit, der [Name der Firme] mit medizinischen Geräten und physiologische Signalverarbeitung macht. Ich habe ein Praktikum mit physciologische Modellierung (mit MATLAB und Simulink) von der Vokaltrakt gemacht. Diese Ehrfahrung konnte Nutzen sein in Ihre Hals, Nase, und Ohren Abteilung oder in anderen Abteilung, die physciologische Modellierung braucht. Ich habe auch Interesse in neurologischen Signalverarbeitung, weil ich mache jetzt ein Kurs in diese Fach, und Ihre Arbeit in diesem Fach interessiert mich viel.

Ich stehe zur Verfügung, um von Januar bis Juli 2013 zu arbeiten. Ich habe im Anhang weitere Informationen über meine bestimmtes Programm.

Wenn Sie Interesse haben in über meine Qualifikationen sprechen, bitte kontaktieren Sie mich mit email (______________) oder rufen Sie mir unter _______________ an.

silver or black?

a.) yes

b.) no

c.) could go either way

If "a", what would it take for you to stop believing? If "b", what would it take for you to believe? If "c", what would it take for you to have a definitive answer? If there is nothing that would make you change your belief, please say why.

I have a sinusoidal type graph, but I would like to create a new graph that only includes the points that are both negative and increasing from the original graph. Is there a simple function for this?

I can hear electric guitar coming from one of the rooms above mine. However, when I go to that floor, I can't hear anything at all. Does electric guitar music spread downward through the floor/my ceiling more strongly than it spreads through walls?

Approximately how many volts would I have gotten?
