this paper addresses the concept of co 2 laser beam machining (lbm) and development of intelligent knowledge base system (ikbs) for co 2 lbm. feature based design is used for acquiring design specification. for optimization of laser beam machining computer based concurrent engineering environment is used. the ikbs is linked to feature base cad system. the ikbs is also linked to material databas...

Laser beam machining (LBM) is one of the most widely used thermal energy based non-contact type advance machining process. In recent years, researchers have explored a number of ways to improve the LBM process performance by analyzing different factors that affect the quality characteristics of LBM process such as kerf width, kerf taper, surface finish etc. It is revealed from the literature th...

Abattoir blood meal is rich in nitrogen and its potential as a co-composting material for horse stable bedding waste was evaluated at two C/N ratios -32 (LBM, low blood meal) and 16 (HBM, high blood meal) - to improve the nutrient contents of the final compost. The mix was composted for 7 days in a 10 tonne/day in-vessel composter and cured aerobically. After 56 days ofcomposting, the ammoniaca...

Ways of accelerating recovery of the mucous membrane immune system in lethally irradiated mice following syngeneic bone marrow transplantation were studied over a 35-day period by quantification of jejunal intraepithelial lymphocytes (IELs) and lamina propria plasma cells. Recovery after a low bone marrow dose allowing 100% animal survival (LBM) was compared with a high (five times minimal) dos...

OBJECTIVE To compare, in Chinese continuous ambulatory peritoneal dialysis (CAPD) patients, the creatinine kinetics method (LBM-CK) and the anthropometric method (LBM-AM) for determining lean body mass (LBM). DESIGN Single-center cross-sectional study. PATIENTS AND METHODS We studied 151 unselected CAPD patients (78 males, 73 females). We calculated LBM-CK and LBM-AM using standard formulas...

The effect of biosynthetic human growth hormone (BSHGH) on postoperative protein and energy metabolism has been studied in patients who had major gastrointestinal surgery. Seven patients received placebo and seven patients received BSHGH, 0.1 mg/kg/24 h, for the first six postoperative days. Mean total nitrogen excretion was significantly lower with BSHGH (31.5 +/- 2.4 g N) (2287 +/- 160 mmol) ...

LBM should be taken into account (1 ). However, as shown here and previously (3 ), the contribution of LBM to variations in serum creatinine is small. The group of subjects studied were all females, and this may account for the low contribution. However, their LBM covered a wide range (23.0–53.7 kg), and thus it is likely that the findings here would be widely applicable. These results suggest ...

Lattice Boltmzmann Methods (LBM) have been proved to be very effective methods for computational aeroacoustics (CAA), which have been used to capture the dynamics of weak acoustic fluctuations. In this paper, we propose a strategy to reduce the dispersive and disspative errors of the two-dimensional (2D) multi-relaxation-time lattice Boltzmann method (MRT-LBM). By presenting an effective algori...

It ha been proved that the lattice Boltzmann Methods (LBMs) are very efficient for computational fluid dynamics purposes, and for capturing the dynamics of weak acoustic fluctuations. Especially, the multi-relaxation-time lattice Boltzmann method (MRT-LBM) appears as a very robust scheme with high precision. It is well-known that there exist several free relaxation parameters in the MRT-LBM. Al...
