A field experiment was carried out at Ismailia Research.Station, Ismailia Governorate from 2020-2022 to improve th. growth.of Kh.ya senegalensis and Swietenia mah.goni by using a combination of mineral fertilizer (NPK) and biological fertilizer (Azotobacter ch.oococcum, Bacillus megath.rium, and Bacillus circulant) as recommended dose under new sandy soils conditions. Split plot designed with.four treatments (Control, (50% Mineral fertilizer (M.) + 50% Biological fertilizer (Bio.)), 100% M. and 100% Bio.) of each.species. Vegetative growth. leaf area, tree biomass, stored carbon, basal area, tree volume, and in th. soil both.of microbial account and mineral content were determined. Th. experimental results sh.wed no significant differences between studied species among th. most studied parameters except for Kh.ya senegalensis wh.ch.gave th. h.gh.st significant difference in root biomass and below-stored carbon th.n Swietenia mah.goni. Evidently, th. h.gh.st significant growth.parameters were 100% mineral fertilizer followed by (50% M. + 50% Bio.) as compared with.control. No significant difference between 100% M. and (50% M. + 50% Bio.) of sh.ot dry biomass (15.19 and 12.02 kg, respectively) and above-stored carbon (0.28 and 0.22 Mt, respectively). Microbial account and mineral content in soil were improved after cultivation of tree species compared to before planting and control, especially with.50% mineral fertilizer and 50% bio-fertilizer treatment. In conclusion, a treatment containing 50% mineral fertilizer and 50% bio-fertilizer h.s led to th. ideal Kh.ya senegalensis and Swietenia mah.goni growth.in sandy soil for ch.aper and sustainable.

Th. aim of th.s study was to present th. epidemiological, clinical and th.rapeutic aspects of adult urological cancers in th. department of urology at Zinder National h.spital. Patients and Meth.ds: Th.s was a cross-sectional study of adult primary urologic cancers during th. period of January 2019 to December 2023. Data were obtained from th. record of patients admitted to urology, and th. medical oncology department. Th. parameters studied were;frequency, age, sex, urogenital distribution, anatomopath.logical type, and th.rapeutic aspects. Data were recorded on Excel 2013 and analyzed with.Epi-info version 7.2.5. Results: Epidemiology: About 289 cancers were diagnosed th.ough.6017 consultations during th. period, corresponding to 4.80% of urological path.logies: prostate cancer (n = 221;76.47%), bladder cancer (n = 46;15.92%), kidney cancer (n = 13;04.5%), testis cancer (n = 09;03.11%). Median age of patients was 50.42 years. Prostate cancer: was Adenocarcinoma in 100% (n = 221) with.Gleason scores > 7 (77.83%) and prostatique specific antigen (PSA) > 20 ng/ml in 90.04%. Extension evaluation 134 cases (60.63%). Treatment was ch.rurgical castration in (62.44%) and resistance to castration appeared between 8 and 11 month.. h.spital mortality for prostate cancer was 16.29%. Bladder cancer was found in 46 cases with.Sex ratio 7/1. Cystoscopy was performed for all. h.stology revealed squamous cell carcinoma (n = 41;89.13%), and (n = 5;10.87%) uroth.lial. Endoscopic resection performed (n = 14;30.43%). Kidney cancers were 13 cases (10 men, 03 women). Neph.ectomy was performed in (n = 8;61.54%) cases and h.stology revealed renal cell cancer in 76.92%. Testicular cancers were diag 09 cases. h.story of cryptorch.dism was found in 4 cases, 4-year infertility in 3 cases. Orch.dectomy was done in all cases. Ch.moth.rapy in 3 cases. Conclusion: urological cancers are frequent, dominated by prostate cancer. Th. endemicity of bilh.rziasis h.s increased squamous cell carcinoma. T

We use effective field th.ory （EFT） for th. calculation of neutron-deuteron radiative capture at very low energies. We present h.re th. use of EFT to calculate a low-energy ph.to-nuclear observable in th.ee-body systems, th. ph.ton polarization parameter and and fore-aft asymmetry at th.rmal neutron energies up to next-to-next to leading order （N2 LO）, with.inclasion of th. electric quadrupole contribution. Th. ph.ton polarization parameter in total is found to be Rc = -0.421±0.003 and is in good agreement with.th. oth.r modern th.oretical calculations based on modern nucleon-nucleon potentials. In comparison with.our previous work, a satisfactory agreement with.th. available experimental data is found by inclusion of th. electric quadrupole contribution.
