The Leg 104 organic geochemistry program consisted of monitoring (a) hydrocarbon gases, (b) organic and inorganic carbon, and (c) parameters resulting from Rock-Eval pyrolysis at three sites on the Vdring Plateau. The results amplify some of those obtained earlier on Deep Sea Drilling Project (DSDP) Leg 38. In a regional sense there is an inverse correlation between amounts of hydrocarbon gas a...

Assignment: Section 1-1: 1.1, 1.4, 1.8, 1.12 Section 1-2: 2.3, 2.6 Section 1-3: 3.1, 3.2, 3.3, 3.6(b), 3.8 Section 1-1 1.1 Prove ∑n j=0 j 2 = 1 6n(n + 1)(2n + 1) for all natural numbers n. Proof. Let P(n) say ∑n j=0 j 2 = 6n(n + 1)(2n + 1). Then P(n) is a predicate in the variable n. (1) P(0) says ∑0 j=0 j 2 = 6 [0(0 + 1)(2 · 0 + 1)]. This is true since both sides evaluate to 0. (2) Let n ∈ N, ...

The β-lactamase inhibitor avibactam (NXL104) displays potent inhibition of both class A and C enzymes. The in vitro antibacterial activity of the combination ceftazidime-avibactam was evaluated against a clinical panel of Pseudomonas aeruginosa isolates. Avibactam offered efficient protection from hydrolysis since 94% of isolates were susceptible to ceftazidime when combined with 4 μg/ml avibac...

The in vitro activity of ceftazidime in combination with NXL104 versus 470 Pseudomonas aeruginosa clinical isolates was evaluated using Clinical and Laboratory Standards Institute (CLSI) broth microdilution methods. Ceftazidime had MIC₉₀s of 8 μg/ml and 32 μg/ml in the presence and absence of NXL104, respectively. Of 25 multidrug-resistant P. aeruginosa isolates, the percentages with a ceftazid...

subfamily Gardennieae, family Rubiaceae. It is widely distributed in tropical and sub-tropical regions, especially in Asia and Africa. Craib reported that R. siamensis CRAIB is synonymous with R. longiflora HOOK f., R. uncata RIDL., Griffithia siamensis MIQ. and Webera siamensis KURZ. It can be found in all parts of Thailand and Burma, especially in humid regions. This plant is known by various...
