The effect of rhGM-CSF therapy on the lymphocyte phenotype; on the proliferative responses to the mitogen phytohemagglutinin, Candida albicans, and tetanus toxoid antigens; and on the natural killer (NK) activity of the circulating lymphocytes was studied. Samples were collected before (baseline) and twice during the rhGM-CSF administration. The absolute number of circulating lymphocytes remained relatively constant during the first period, but experienced a significant increase (P less than .001) during the second period. The increase was most prominent in the B cells (P less than .001), but the T cells (P less than .016) also increased. Detailed investigation of lymphocyte subsets showed an increase of the markers CD38 (Leu17), HLA- DR, and the transferrin receptor throughout the treatment course giving evidence of lymphoid cell activa...

There are 25 crude palm oil (CPO) Mills in Aceh located in 8 districts with 551.12 tons/hour total capacity. The mills are concentrated in five districts along the western and eastern coasts, Aceh Utara, Aceh Timur, Aceh Tamiang, Nagan Raya, and Aceh Singkil (including the newly-established municipality of Subullusalam). As the climatic conditions in the Aceh are suitable for palm trees, the oil palm plantation area has expanded every year. The processing of FFB (Fresh fruit bunches) in palm oil mill produced a biomass residue that mainly consist of EFB (Empty fruit bunches), fiber, shells, and POME (Palm oil mill effluent). This study investigates the potential usage of biomass residue from palm oil mills in Aceh province. Results of the study indicated that the fiber and shells are mainly used as fuel for the mill boilers to generate heat and electricity for the whole plant. The EFB is disposed and spread on the plantation, incinerated or dumped in unmanaged sites. The POME is treated in the anaerobic and aerobic ponds, then normally being discharged into waterways or rivers. In some mills, the treated POME was spread to the plantation for fertilizer. Based on investigation on site, it shows that the load factor of the mill is only about 70% of capacity, thus the mills are inefficient since a lot of energy is lost. The use of EFB is very potential to be implemented in Aceh since this province produce of 724,185 ton EFB per year. With the total capacity of 551.12 tons/hour, palm oil mills in Aceh produce about 426.12 tons/hr of POME that also can be converted into energy. If 3.37 million ton FFB are treated in Aceh CPO mills, biogas energy of about 1.51 millions GJ will be produced.

The structural, optical, and chemical properties of the low-dimensional (average diameter, 64.0±10.0 nm) doped Al.ZnO nanoparticles were exemplified using various techniques such as UV/visible, FT-IR, Raman spectroscopy, x-ray powder diffraction (XRD), and Field-emission scanning electron microscopy (FE-SEM) etc. Al.ZnO is an interesting doped nanoparticles for implementation in chemical sensing by reliable I-V method, where hazardous chemical (phenyl hydrazine, PhHyd) is used as a target chemical. The sensor performances are investigated using Al.ZnO nanoparticles embedded onto silver electrodes (AgE, active surface area, 0.0216 cm 2), which shows the sensitivity, stability, and reproducibility of the sensor improved significantly. In analytical investigation, the calibration plot is linear over the large concentration range (10.0 μM to 0.05M), where the sensitivity is 1.1432 ± 0.10 μAcm-2 mM-1 with a detection limit (LOD) of 1.215 ± 0.02 μM based on signal to noise ratio in short response time. Therefore, it is concluded that the morphologies and the optical features can be implemented to large-scale in transition-metal-doped semiconductor nano-materials as well as efficient chemical sensors.

The mechanisms by which the bacterium has reached high levels of infection previously unrecorded in the Laurentian Great Lakes are presently unknown. Research involving reservoirs and mechanisms of R. salmoninarum transmission in fish is lacking because of the ecologic complexity of heterogeneous habitats and the lack of adequate funding. Herein, we report on the isolation of R. salmoninarum from the kidneys of the sea lamprey (Petromyzon marinus). The bacterium was cultured from kidneys of 16% and 4% of lampreys collected from two locations within the Lake Ontario watershed in 2003 and 2004, respectively. The identity of bacterial colonies was verified with the nested polymerase chain reaction and quantitative enzyme-linked immunosorbent assay.

The microstructure and magnetic properties in high temperature hard magnetic alloy have been studied against various milling times in high energy ball milling. The average particle size varies from 1 μm to 50 μm for ball milling times of 30–180 minutes while keeping the constant weight of balls to powder ratio. The Samarium loss increases in the form of its oxide (Sm2O3) and results in an additional phase in microstructure. Due to this additional phase at grain boundaries and triple points, and Sm loss results in the formation of a kink in the second quadrant of demagnetizing curve. This kink shifts from second quadrant of demagnetizing curve to first quadrant with the increase of amount of Sm loss and additional phase in microstructure. The thermomagnetic analysis, X-ray diffraction, microstructure, and chemical composition analysis have identified the additional phase probably the 5:19R (Sm,Zr)(CoFeCu) phase. The best shape of the demagnetizing curve has been obtained after 60 min of ball milling time with good loop squareness and improved magnetic properties at room and high temperature.

Fast diagnosis of power quality disturbances is important so as to assist network operators in performing counter measures and implementing suitable power quality mitigation actions. In this study a novel method for performing power quality diagnosis is presented by using the S-transform and rule based classification techniques. The proposed power quality diagnosis method was evaluated for its functionality in detecting the type of short duration voltage disturbances and identifying the cause of the disturbances which may be due to permanent or non permanent faults. Based on the results, this new method has the potential to be used in the existing real time power quality monitoring system in Malaysia to expedite the diagnosis on the recorded voltage disturbances.

The structures of as-grown Ag 2 O micro-flower (composed of nanosheets) were characterized using powder X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), UV/visible, Fourier transform infra-red (FT-IR), and Raman spectroscopy's etc. The chemical composition of Ag 2 O nanostructures was investigated by energy-dispersive X-ray spectrum (EDS). As-grown Ag 2 O nanosheets were applied for the chemical sensing using simple I-V technique in liquid phase system, where acetone was used as a target analyte. The analytical performances of acetone sensors with Ag 2 O using glassy carbon electrode (GCE) have good sensitivity, lower detection limit, and long-term stability in their electro-chemical responses. The calibration plot was linear (R = 0.9462) over the large dynamic concentration range (0.13 lM to 0.67 M). The sensitivity was calculated to 1.6985 lA cm À2 mM À1 with lower detection limit (0.11 lM) based on a signal/noise ratio (3N / S) in short response time. Finally it was confirmed that the micro-flower morphologies (composed of nanosheets) and the optical features of silver oxide can be extended to a large range in un-doped semiconductor nanomaterials for proficient chemical sensor applications.
