The risk of rad.ation-ind.ced.second.cancer and.the late tissue loss d.e to Off-field.d.ses in rad.otherapy remain a serious concern. Monte Carlo (MC) simulation is currently one of the most accurate method. for calculating these d.ses. MC simulation mod.l based.on the Particle Simulation Tool (TOPAS) has been d.veloped.to simulate the off-field.d.se of an Elekta Synergy linear accelerator (Linac) emitting 6 MV photons. Measurements were taken in a water phantom using an ionization chamber to valid.te this mod.l. The Percentage d.pth d.se (Pd.) at the d.pth of 0.0, 5.0, 10.0 and.15.0 cm from the beam axis for a 10 × 10 cm2 field.size was measured.and.simulated. Off-field.d.se profiles at the d.pth of 1.5 (d.ax), 5.0 and.10.0 cm for field.sizes of 5 × 5, 10 × 10, 15 × 15, and.20 × 20 cm2 respectively were measured.and.simulated. Comparison of measured.and.simulated.off-field.d.se values showed.a good.agreement. The average gamma passing rate of the Pd.s and.profiles curves for off-field.d.ses were 87.5% and.98.11% respectively. The local d.se d.fference based.on the Pd. curve between the measured.and.simulated.was less than 6.0 % for all locations. For all field.size consid.red.in this stud., the average d.fference between profile curves for off-field.d.se measured.and.simulated.was 9.1%. Pd.s and.Profiles curves for off-field.d.se simulation uncertainties were less than 2.0% and.1.0% respectively. TOPAS-MC simulation mod.l d.veloped.is a good.representation of our 6 MV Linac Elekta Synergy for assessing off-field.d.se, which would.be the primary cause of some second.ry cancers.

The capital of Guinea, Conakry, faces a notable d.fficulty d.e to a water shortage, which is worsened.by the rapid.increase in population and.urban d.velopment. The Guinean Water Company (SEG) faces challenges in supplying water to the entire city d.e to its limited.area of approximately 420 km2 and.a population of 2 million. Moreover, the population growth rate is anticipated.to increase d.amatically, exacerbating the d.fficulty of fulfilling future water requirements. As a result, this stud. employs d.ta from the Knoema website and.the Institute of National Statistics of Guinea (INS) to examine the water prod.ction and.d.stribution process by the SEG. The stud. examines the challenges related.to water scarcity in Conakry and.suggests strategies to assist the city in managing the present circumstances and.planning for the future. The primary objective is to get a long-lasting water supply and.uphold.water quality to ad.ance public health.

Artificial fishpond. play a pivotal role in global aquaculture, serving as a source of livelihood.and.nourishment for many communities. Ensuring the sustained.health and.prod.ctivity of Fishes in these environments relies heavily on water quality management. This assessment was d.ne to d.termine the water quality of ten artificial fishpond. in the south-eastern part of Sierra Leone using twelve physicochemical factors (pH, BOd. EC, Td., turbid.ty, COd. Fe2+, Mg2+, Ca2+, NH3, , and.alkalinity) to find.out the Water Quality Ind.x (WQI) and.spatial d.stribution of respective parameters. The assessment of artificial fishpond. using WQI and.Inverse d.stant Weighting (Id.) integration represents a relatively und.rexplored.area within the d.main of environmental water resources. The WQI was d.termined.using the “Weighted.Arithmetic Water Quality Ind.x’’ method. The results of WQI in the stud. area range from 65.05 to 147.26. Several locations have water quality d.emed.unsuitable for consumption, while others range from good.to very poor. It is essential to ad.ress and.improve water quality in locations categorized.as unsuitable for consumption and.very poor to ensure safe and.healthy water sources. It was also clear from the calculation that the smaller the mean concentration value of the pH as compared.to the id.al value (7), the smaller the WQI value and.the better the water quality. To keep the artificial fishpond.water in good.cond.tion, mass d.mestic use should.be controlled. and.d.aining of surround.ng organic matter should.be stopped.in pond.

Previously,chemists working in synthesis were jealous of biologists since the enzymes found.in nature usually exhibited.great catalytic properties(e.g.,high catalytic efficiency,excellent selectivity such as substrate selectivity,regioselectivity and.stereoselectivity).However,biological systems lack many counterparts of reactions wid.ly used.in chemical synthesis.

We have reported.the characteristics of a Z-scan for the poly(azaneylylid.ne-acylene)(d.ZA) polymer, as nonlinear med.um with a large nonlinear phase shift using continuous-wave(CW) laser beam. It has been verified.that the Fresnel d.ffraction mod.l is applicable for analyses of Z-scan measurements with d.ZA polymer at high laser power. It was found.that Z-scan curves with peak-to-valley features appear as the applied.light intensity increases in the case of a large nonlinear phase shift. The Z-scan experiments were carried.out using a CW laser to verify the theoretical calculations in the case of a large nonlinear phase shift mod.l. Our results show good.agreements between the experimental d.ta and.the proposed.theoretical mod.ls.

Anomalous ion heat transport is analyzed.in the T-10 tokamak plasma heated.with electron cyclotron resonance heating(ECRH) in second.harmonic extra-ord.nary mod.. Pred.ctive mod.ling with empirical scaling for Ohmical heat cond.ctivity shows that in ECRH plasmas the calculated.ion temperature could.be overestimated. so an increase of anomalous ion heat transport is required. To stud. this effect two scans are presented. over the EC resonance position and.over the ECRH power. The EC resonance position varies from the high-field.sid. to the low-field.sid. by variation of the toroid.l magnetic field. The scan over the heating power is presented.with on-axis and.mixed.ECRH regimes. d.scharges with high anomalous ion heat transport are obtained.in all consid.red.regimes. In these d.scharges the power balance ion heat cond.ctivity exceed. the neoclassical level by up to 10 times. The high ion heat transport regimes are d.stinguished.by three parameters: the ratio Te/Ti, the normalized.electron d.nsity grad.ent R/■, and.the ion–ion collisionality νii~*. The combination of high Te/Ti, high νii~*, and.R/■=6-10 results in values of normalized.anomalous ion heat fluxes up to 10 times higher than in the low transport scenario.
