Co-composting of poultry manure and rubber wood sawdust was performed with the ratio of 2：1（V/V） for a period of 60 days. An investigation was carried out to study the extracellular enzymatic activities and structural degradation utilizing Fourier transform infrared spectroscopy（FT-IR）, thermogravimetry and differential thermal analysis（TG/DTA）and scanning electron microscopy（SEM）. The microbial succession was also determined by using denaturing gel gradient electrophoresis（DGGE）. The compost was able to reach its highest temperature of 71°C at day 3 and stabilized between 30 and 40°C for 8 ***, FPase and β-glucosidase acted synergistically in order to degrade the cellulosic substrate. The xylanase activities increased gradually during the composting and reached the peak value of 11.637 U/g on day 35, followed by a sharp decline. Both Li P and Mn P activities reached their peak values on day 35 with 0.431 and 0.132 U/g respectively. The FT-IR spectra revealed an increase in aromaticity and a decrease in aliphatic compounds such as carbohydrates as decomposition proceeded. TGA/DTG data exhibited significant changes in weight loss in compost samples, indicating degradation of organic matter. SEM micrographs showed higher amounts of parenchyma exposed on the surface of rubber wood sawdust at day 60, showing significant degradation. DGGE and 16 S r DNA analyses showed that Burkholderia sp., Pandoraea sp., and Pseudomonas sp. were present throughout the composting process. Ornithinibacillus sp. and Castellaniella ginsengisoli were only found in the initial stage of the composting, while different strains of Burkholderia sp. also occurred in the later stage of composting.

Covid 19 epidemic has caused a lot of concern especially in the obstetric and neonatal populations. The fact that it is a new disease and the fact that there are sparse studies available have doubled our worries. Our study provides some answers. This a retrospective study carried out in Mediclinic Al-Noor hospital in Abu Dhabi. Our study revealed no adverse effects on the neonates and no vertical transmission. Given the physiologic and immune function changes in pregnancy, they might be considered at a higher risk of developing more complications, but it needs a longer duration of the study with larger sample size. Statistical analysis could not be possible in our study due to the smaller sample size, and we plan to continue the study further in the future to obtain a larger pool of data to validate the findings more accurately. The incidence of covid positive mothers might not reflect today’s covid situation because we carried out the study during the lockdown and there might be an increase in the incidence after lockdown.

Objective: To evaluate the susceptibility of Mycobacterium aurum and Mycobacterium smegmatis in vitro to the essential oils obtained from two medicinal plants: Thymus satureioides(T. satureioides) and Mentha pulegium(M. pulegium), and to study their chemical ***: The aerial parts of T. satureioides and M. pulegium(leaves and stems) were hydro-distillated using a Clevenger-type apparatus and essential oils were analyzed and identified by gas chromatography-mass spectrometry. Antimycobacterial screening of essential oils was performed on the basis of the inhibition zone diameter by disc diffusion method against two mycobacterial strains whereas the minimal inhibitory concentration and minimal bactericidal concentration were determined by using the micro-dilution ***: Chemical analysis of their aerial part's essential oils gave as major compounds,borneol(34.26%), carvacrol(31.21%) and thymol(3.71%) for T. satureioides and R(+)-pulegone(75.48%), carvone(6.66%) and dihydrocarvone(4.64%) for M. *** their antimycobacterial effect evaluation, using the micro-dilution method,indicated that minimal inhibitory concentration values of T. satureioides essential oil ranged from 0.062% to 0.015%(v/v) and from 0.125% to 0.031%(v/v) for M. pulegium respectively against Mycobacterium aurum and Mycobacterium ***: It is clearly evident from the results obtained that the Moroccan medicinal plants have great potential to be used as anti-tuberculosis agents. These findings may help scientists to undertake several research projects to discover useful natural product as new anti-tuberculosis drug.
