conclusions the mssrhs could be considered as a more suitable packing material for long-term biofilter operation to remove h2s pollution. results in this study, after 53 days of operating time and 54 g/m3h mass loading, the ph values in the ss and mssrhs packed filters were reduced from 6.8 to 1.8 and from 6.9 to 3.4, respectively. the mssrhs packed filter showed more buffering capacity to resi...

while w(d) = 4=15 and we conclude that, in any event, w(B 3) 1. Case 3. Suppose jB 3 j = 4. B 3 cannot contain an X 1 item, since 1=2 + 3(1=5) > 1. Neither can it contain two X 2 items, since 2(1=3) + 2(1=5) > 1. Similarly, it cannot contain four X 3 items, since each has size greater than 1/4. However, if it contains three items of type X 3 and one of type X 4 , then w(B 3) 3(4=15) + 1=5 = 1. ...

method previously employed by westoo for the determination of alkylmercury compounds was producing very wide picks during g.c. analyses. changing the column temperature, carrier gas flow and pressure did not supersede the problem. therefore change in packing materials was experienced. 5% dc-200 on gas-chrom did not work. a packing material used for chlorinated hydrocarbons w, 80-100 mesh. as th...

self compacting concrete (scc) specimens with limestone (l) and quartz (q) powders were formulated. the influence of the type of the powder on the properties of fresh and hardened concrete was evaluated. dense packing theories were used for mix design of samples. the equation of fuller and thompson for particle size distribution (psd) of aggregates was modified with considering fine particles a...

In computational geometry, packing problems ask whether a set of rigid pieces can be placed inside a target region such that no two pieces overlap. The triangle packing problem is a packing problem that involves triangular pieces, and it is crucial for algorithm design in many areas, including origami design, cutting industries, and warehousing. Previous works in packing algorithms have conject...

We analyze the problem of packing squares in an online fashion: Given a semi-infinite strip of width 1 and an unknown sequence of squares of side length in [0, 1] that arrive from above, one at a time. The objective is to pack these items as they arrive, minimizing the resulting height. Just like in the classical game of Tetris, each square must be moved along a collision-free path to its final...
