These are the lecture notes from week 2 of Ma1d, the Caltech mathematics course on sequences and series. 1. Limits Superior and Inferior So: most of the definitions and theorems we’ve developed so far for sequences are centered around the concept of convergence – we have lots of ways of talking about when things converge, where they converge to, and under what conditions they will be forced to ...

Due to an increasing demand of leaf vegetables, and hence their economic importance in the tropics, it is very common that excessive fertilizer N rates are applied to vegetable gardens and fields to attain high yield. This calls for more information on their nutrient requirements. In this study, we designed experiments to explore the effect of organic N levels on the yield and agronomic N use e...

background: the appropriate colon cleansing is a major determinant of quality of colonoscopy. the aim of this study was to compare the efficacy and tolerability of the morning (am) peg (polyethylene glycol) solution to previous-evening (pm) peg solution for the afternoon colonoscopy. methods: this comparative study compared the am to pm prep for afternoon outpatient colonoscopy. the subjects ra...

Voriconazole and anidulafungin in combination are being investigated for use for the treatment of pulmonary aspergillosis. We determined the pulmonary disposition of these agents. Twenty healthy participants received intravenous voriconazole (at 6 mg/kg of body weight every 12 h [q12h] on day 1 and then at 4 mg/kg q12h) and anidulafungin (200 mg on day 1 and then 100 mg every 24 h) for 3 days. ...

The advantage of additive manufacturing (AM) (e.g. reasonable time and expense in prototyping, and reliable product) has triggered the idea of using this method in manufacturing of marine vessels components. The current article tries to introduce basic concepts of AM method and its application in marine industry; have a glance at additive-manufactured parts microstructure; elaborate the challen...

Phosphinothricin, Methionine Sulfoximine, Glutamine Synthetase, Am m onia Accum ulation, Photosynthetic Rate The effects o f DL-phosphinothricin and L-methionine sulfoxim ine on the enzymes o f nitrogen assimilation were studied. Furthermore we investigated the accumulation o f am m onia and the photosynthetic activity after the treatment o f mustard plants with phosphinothricin. Phosphino­ thr...
