Four identical 37.5 Liter UASB reactors R1, R2, R3 and R4 were used to study the effect of sulfate concentration on granule formation. Diluted molasses with COD range 1000–1300 mg/l were used as feed and acclimated cow manure was used as seed. Concentration of sulfate ions in the four reactors were 100, 500, 1000 and 1500mg/l. Granules were observed in R2 after 33 days from startup time, while ...

In this paper T , U are non empty topological spaces, t is a point of T , and n is a natural number. Let S be a topological space and let T be a non empty topological space. Note that every function from S into T which is constant is also continuous. The following two propositions are true: (1) L01(0, 1, 0, 1) = id[0, 1]T . (2) For all real numbers r1, r2, r3, r4, r5, r6 such that r1 < r2 and r...

To identify a set of genes involved in the development of radiation-induced tumorigenesis, we used DNA microarrays consisting of 1176 mouse genes and compared expression profiles of radioresistant cells, designated NIH3T3-R1 and NIH3T3-R4. These cells were tumorigenic in a nude mouse grafting system, as compared with the parental NIH3T3 cells. Expression of MDM2, CDK6 and CDC25B was found to in...

The tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) is a potent inducer of apoptosis in many cancer cells. However, a significant proportion of tumours are TRAIL-resistant erecting a major hurdle for a successful TRAIL-based treatment regimen in the future. In this context, it would be a major advantage to be able to identify the tumours that respond to TRAIL. The existence of ...

The current research attempted to evaluate the impact of various thawing techniques (R0: control group, R1: water immersion thawing, R2: low-temperature R3: combined then R4: combination low temperature and R5: oven thawing) on quality, microbiota, organoleptic characteristics chicken meat fillets. findings showed that moisture content varied from 74.43 72.33%; loss peaked in R1 at 4.66%, while...

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF family that interacts with several receptors, including TRAIL-R1, TRAIL-R2, and TRAIL-R4. TRAIL-R1 and TRAIL-R2 can induce apoptosis of cancer cells and activate the transcription factor NF-kappaB. TRAIL-R4 can activate NF-kappaB and protect cells from TRAIL-induced apoptosis. Here we show that TRAIL-R1...

Meloidogyne incognita (Kofoid and White) Chitwood has been separated into four races (R l -R4) based on the ability of different populations to parasitize 'NC95' tobacco and 'Deltapine 16' cotton (7). Since the designation of races within this species, several workers have at tempted to characterize them on the basis of reproduction on a common host. Araujo et al. (1) compared the reproduction ...
