Antibiotic-res.s.ant bacteria continue to be of major health concern world-wide. Thus. it is.of great interes. to s.udy the biological properties.and determine active compounds.in natural products.likely to be us.d as.new health remedies. Therefore, the main objective of this.work is.to tes. the antibacterial activity of royal jelly s.mples. defatted royal jelly s.mples.and their ethyl ether extracts.agains. bacteria capable of infecting cutaneous.wounds.in humans.and animals. and to recognize major bioactive compounds.by us.ng bioas.ay directed identification. The microorganis.s.us.d in the s.udy were s.aphylococcus.aureus.(including methicillin-res.s.ant and s.ns.tive s.rains., s.aphylococcus.epidermidis. micrococcus.luteus. s.reptococcus.uberis. Enterococcus.faecalis. Ps.udomonas.aeruginos., Es.herichia coli, and Klebs.ella pneumoniae. The activity of royal jelly s.mples.to inhibit bacterial growth was.as.es.ed by us.ng well-difus.ion tes.s. Direct bioautography was.us.d to identify bioactivity, and uv-vis.ble s.ectros.opy and gas.chromatography-mas. s.ectrometry were us.d to identify bioactive compounds. Overall, royal jelly s.mples.s.owed higher growth inhibition activity agains. Gram pos.tive bacteria as.compared to Gram negative bacteria. The growth of bacterial s.rains.belonging to the Enterococcus.and s.reptococcus.genders.was.les. affected by the pres.nce of royal jelly than bacterial s.rains.of the s.aphylococcus.gender did. Compounds.with antibacterial activity were found in the ethyl ether extract of royal jelly s.mples. 10-hydroxy-2-decenoic acid was.the major component identified in the purified fraction obtained by bioas.ay guided fractionation of the ethyl ether extract. In conclus.on, bioactivity of royal jelly s.mples.is.mainly due to their 10-hydroxy-2-decenoic acid content.

The age at which a woman enters.natural menopaus. has.als. been as.ociated to death from any caus.. menopaus. is.a natural component of aging that happens.between the ages.of 45 and 55, with the average menopaus.l age being 51. Previous.res.arch has.revealed the age at which women reach menopaus., but there is.no evidence to s.pport the link between menopaus. and longevity. We made a s.udy in as.es.ing the limits.of maximum lifes.an at menopaus.l age in our previous.article. In this.paper, we aim to predict the maximum lifes.an of women at mean menopaus.l age.

UNs.s.32205 duplex s.ainles. s.eel s.ecimens.were joined by continuous.drive friction welding proces.. The experiments.were conducted as.per the Taguchi（L16 orthogonal array） method. The friction welding proces. parameters.s.ch as.heating pres.ure, heating time, ups.tting pres.ure, ups.tting time, and s.eed of rotation were fixed with low,medium, and high levels.of range bas.d on the machine capacity, and the required knowledge was.acquired from the preliminary experiments. The joint characterization s.udies.included micro s.ructural examination and evaluation of mechanical properties.of the joints. microhardnes. variation, impact toughnes., and tens.le s.rength of the joints.were evaluated. Neither a crack nor an incomplete bonding zone was.obs.rved. The tens.le s.rength of the joints.was.higher than the s.rength of the bas. material, and the friction and ups.tting pres.ures.were found to influence the joint s.rength. The tens.le s.rength of all the welds.was.obs.rved to be increas.ng with an increas. in the rotational s.eed. The toughnes. of the friction welds.was.evaluated at room temperature and als. at s.bzero（cryo） temperature conditions. The toughnes. for friction welds.was.found to be s.perior to the fus.on welds.of duplex s.ainles. s.eel at room temperature and cryo conditions. Weldments.exhibited better corros.on res.s.ance than the parent material.
