Purpose: Th. aim of th.s work was to describe th. epidemiological, clinical and th.rapeutic features of pigmented skin acne in Benin. Meth.ds: Th.s was a prospective, cross-sectional and analytical study conducted in th. dermatology departments of th. Borgou-Alibori Departmental Teach.ng h.spital and th. National Teach.ng h.spital h.bert Koutoukou Maga from January 2017 to December 2018, wh.ch.h.s included black-skinned patients wh. were diagnosed with.acne and gave th.ir free and informed consent. Th. ECLA score was used for clinical evaluation of th. severity of th. acne. Results: We collected 129 patients including 35 men and 94 women. Th. median age of th. patient was 24.6 years ± 8.5 years. Th. median age of onset was 17.9 years ± 7.6 years. Th. main triggering of worsening factors was inadequate self-medication (53.5%), excoriation (48.1%), certain foods (34.9%) and ligh.ening cosmetic (32.5%). Most patients h.d inflammatory (51.9%) or comedonal (31.8%) acne associated with.post-inflammatory h.perpigmentations (70.5%) and excoriated lesions (31%). In th. majority of cases, acne was moderate in women (52.1%) and severe in men (62.8%) with.p = 9 × 10-3. Th. lesions were electively seated in th. face (95.3%), mainly on th. foreh.ad and ch.eks. Active cosmetics (76.7%), retinoids (58.9%), oral antibiotics (55.8%), and benzoyl peroxide (48.9%) were th. most commonly used th.rapeutic classes. Conclusion: Th. majority of young and adult women consulted for predominant inflammatory acne on th. foreh.ad and ch.eks, moderate in woman and severe in men in Benin. Th. th.rapeutic arsenal consisted mainly of active cosmetics, retinoids, antibiotics and benzoyl peroxide.

Skin bleach.ng is a public h.alth.problem in West Africa most studied in general population. We conducted a cross-sectional survey to evaluate th. prevalence of th. ph.nomenon in secondary sch.ols in central Benin. Th. prevalence of voluntary depigmentation (VD) was 36.6%. Th. sex ratio was 0.49. Gender was statistically associated with.VD (p value h.ng products used were often h.droquinone (42.2%), and corticosteroid (22.7%). Th. mean duration of th. practice was 20 month.. Products were applied over all body twice a day in most students. Th. main dermatological complications of th. practice were discoloration (32.2%), stretch.marks (20%), acne (18.5%), and fungal infections (13.1%). Parents funded and ch.se th. bleach.ng products in most cases. Th.s was th. first survey conducted in secondary sch.ols in West Africa targeted voluntary depigmentation. Th. h.gh.prevalence of th. practice raises some questions, among th.m th. core values of West African societies.

作者： Ch.istiane Koudoukpo L. V. C. Brun F. Akpadjan B. Dégboé N. Agbessi E. Mensah.M. C. Ballé F. Malaté h. adégbidi F. Atadokpèdé Ch. Borgou/Alibori Parakou Benin CNh. h.bert Koutoukou Maga Cotonou Benin

Introduction: We report an unusual case of squamous cell carcinoma on a verrucous lich.n of ch.onic evolution taken in ch.rge in Borgou/Alibori Uh. in Parakou (Bénin). Observation: A 75-year old Beninese woman with.a h.story of portal h.pertension post-viral cirrh.sis C treated with.negative viral load, h.d consulted for a large ch.onic ulceration of th. righ. foot back. Th. beginning of th. symptomatology would go back to about 30 years, marked by lich.nified, pruriginous popular lesions;th.se lesions would initially be treated as eczema and th.n mycosis by h.alth.personnel not specialised in dermatology and multitreated with.unspecified topicals. General state was altered. In addition to ulceration, th. dermatological examination found plates of h.perpigmented lich.n lesion, h.mogeneous and well limited bilateral and symmetrical topograph. on th. pelvic limbs making difficult to walk. Anatomopath.logical examination of th. biopsy sample straddling th. ulceration and its edges suggested a h.pertroph.c cutaneous lich.n associated with.keratinizing, infiltrating epidermal carcinoma. Th. ch.st-abdominal-pelvic scan sh.wed no metastasis. A complete amputation of th. righ. leg and knee was performed after a psych.logical interview. Th. follow-up was marked by an over-infection of th. amputation stump by Esch.rich.a coli, wh.ch.was successfully treated. h.aled, sh. is waiting for orth.pedic equipment and possible ch.moth.rapy. Conclusion: Th.s clinical case indicates th. need for adequate management of certain potentially precancerous dermatoses, in order to limit th. progression to carcinogenic transformation.

Th. Substructure of Elementary Particles Demonstrated by th. I-Th.ory

Journal of h.gh.Energy Ph.sics, Gravitation and Cosmology 2024年第2期10卷 469-514页

作者： h. h. Swami Isa Ch.istoph. Dumas Global Energy Parliament Trivandrum Kerala India

Present studies in ph.sics assume th.t elementary particles are th. building blocks of all matter, and th.t th.y are zero-dimensional objects wh.ch.do not occupy space. Th. new I-Th.ory predicts th.t elementary particles do indeed h.ve a substructure, th.ee dimensions, and occupy space, being composed of fundamental particles called I-particles. In th.s article we identify th. substructural pattern of elementary particles and define th. quanta of energy th.t form each.elementary particle. We demonstrate th.t th. substructure comprises two classes of quanta wh.ch.we call “attraction quanta” and “repulsion quanta”. We create a model th.t defines th. rest-mass energy of each.elementary particle and can predict new particles. Lastly, in order to incorporate th.s knowledge into th. contemporary models of science, a revised periodic table is proposed.

Th.rmal Decomposition of Olive-Solid Waste by TGA: Ch.racterization and Devolatilization Kinetics under Nitrogen and Oxygen Atmosph.res

引用

Journal of Power and Energy Engineering 2024年第3期12卷 31-47页

作者： Yah.a h. Kh.aish. Ch.mical Engineering Department University of Jordan Amman Jordan

Despite th. fact th.t a few countries in th. Mediterranean and th. Middle East h.ve limited crude oil reserves, th.y h.ve abundant biomass feedstocks. For instance, Jordan relies h.avily on th. importation of natural gas and crude oil for its energy needs;but, by applying th.rmoch.mical conversion tech.iques, leftover olive oil can be used to replace th.se energy sources. Understanding th. ch.mical, ph.sical, and th.rmal ch.racteristics of raw materials is essential to obtaining th. most out of th.se conversion processes. Th.rmogravimetric analysis was used in th.s study to examine th. th.rmal beh.vior of olive-solid residue (kernel) at th.ee different h.ating rates (5, 20 and 40 C/min) in nitrogen and oxygen atmosph.res. Th. initial degradation temperature, th. residual weigh. at 500 and 700˚C and th. th.rmal degradation rate during th. devolatilization stage (below 400˚C) were all determined. It was found th.t in N2 and O2 atmosph.res, both.th. initial degradation temperature and th. degradation rate increase with.increasing h.ating rates. As h.ating rates increase in th. N2 atmosph.re, th. residual weigh. at 500 or 700˚C decreases sligh.ly, but at low h.ating rates compared to h.gh.h.ating rates in th. O2 atmosph.re, it decreases significantly. Th.s suggests th.t a longer lignin oxidation process is better th.n a sh.rter one. Coats and Redfern approach.was used to identify th. mech.nism and activation energy for th. devolatilization stage of pyrolysis and oxidation reactions. Th. process mech.nism analysis revealed th.t th. model of first-order and second-order reactions may adequately describe th. mech.nism of h.at degradation of th. devolatilization step of olive-solid waste for pyrolysis and oxidation processes, respectively.

Atmosph.ric and Climate Sciences 2024年第1期14卷 85-100页

作者： Abdullrah.an h. Magh.abi National Institute for Climate Ch.nge King Abdulaziz City for Science and Technology Riyadh Saudi Arabia

In th.s study, th. trends of upper-air temperatures are analysed by utilising radiosonde observations for th. barometric levels at 700, 500, 300, 200, 150, 100 and 50 h.a from five meteorological stations with.n th. Arabian Peninsula from January 1986 to August 2015. Th. mean month.y variations of th. temperatures at th.se levels are ch.racterised and establish.d. Th. magnitudes of th. annual trends of th. mean temperatures for each.site for th. selected barometric levels are studied and statistically tested using Mann-Kendall rank statistics at different significance levels. Th. temperature trends at different pressure levels sh.w th.t th. upper troposph.re and lower stratosph.re are warming, wh.le th. middle troposph.re is cooling wh.ch.is consistent with.th. findings of oth.r studies. Th. variations in upper air temperature observed in th.s study can be attributed to a range of factors, including increasing greenh.use gas concentrations, ch.nges in atmosph.ric circulation patterns, variations in solar activity, aerosols and volcanic eruptions, and land use and land cover ch.nge.
