We investigate several Hamiltonians for a free particle in a one-dimensional box, in the context of supersymmetric quantum mechanics. Specifically, we study this problem with the Neumann boundary condition, the periodic and antiperiodic boundary condition, and some mixed and complex boundary conditions. This is achieved by using an approach recently proposed which expresses the factorization of the partner Hamiltonians in terms of the probability density and current for the ground-state eigenfunction of one of them.

Biowaste compost can influence soil organic matter accumulation directly or indirectly. A 5-year experiment was conducted to assess the influence of biowaste compost on the process of soil aggregation and soil organic carbon （SOC） accumulation in a Mediterranean vegetable cropping system. The study involved four treatments： biowaste compost （COM）, mineral NPK fertilizers （MIN）, biowaste compost with half-dose N fertilizer （COMN）, and unfertilized control （CK）. The SOC stocks were increased in COM, COMN, and MIN by 20.2, 14.9, and 2.4 Mg ha-1 over CK, respectively. The SOC concentration was significantly related to mean weight diameter of aggregates （MWD）（P 〈 0.05, R^2 = 0.798 4） when CK was excluded from regression analysis. Compared to CK, COM and COMN increased the SOC amount in macroaggregates （〉 250 μm） by 2.7 and 0.6 g kg-1 soil, respectively, while MIN showed a loss of 0.4 g kg-1 soil. The SOC amount in free microaggregates （53-250 ttm） increased by 0.9, 1.6, and 1.0 g kg-1 soil for COM, COMN, and MIN, respectively, while those in the free silt plus clay aggregates （~ 53 ~m） did not vary significantly. However, when separating SOC in particle-size fractions, we found that more stable organic carbon associated with mineral fraction 〈 53 μm （MOM-C） increased significantly by 3.4, 2.2, and 0.7 g kg-1 soil for COM, COMN, and MIN, respectively, over CK, while SOC amount in fine particulate organic matter （POM） fraction （53-250 μm） increased only by 0.3 g kg-1 soil for both COM and COMN, with no difference in coarse POM 〉 250 μm. Therefore, we consider that biowaste compost could be effective in improving soil structure and long-term C sequestration as more stable MOM-C.

Nanotechnology plays a key role in the development of innovative scaffolds for bone tissue engineering(BTE)allowing the incorporation of nanomaterials able to improve cell proliferation and *** this study,Mg-HA-Coll type I scaffolds(Mg-HA-based scaffolds)were nanofunctionalized with gold nanorods(Au NRs),palladium nanoparticles(Pd NPs)and maghemite nanoparticles(MAG NPs).Nanofunctionalized Mg-HA-based scaffolds(NF-HA-Ss)were tested for their ability to promote both the proliferation and the differentiation of adipose-derived mesenchymal stem cells(hADSCs).Results clearly highlight that MAG nanofunctionalization substantially improves cell proliferation up to 70% compared with the control(Mg-HA-based scaffold),whereas both Au NRs and Pd NPs nanofunctionalization induce a cell growth inhibition of 94% and 89%,*** evidences were found for the osteoinductive properties showing relevant calcium deposits(25% higher than the control)for MAG nanofunctionalization,while a decreasing of cell differentiation(20% lower than the control)for both Au NRs and Pd NPs *** results are in agreement with previous studies that found cytotoxic effects for both Pd NPs and Au *** excellent improvement of both osteoconductivity and osteoinductivity of the MAG NF-HA-S could be attributed to the high intrinsic magnetic field of superparamagnetic MAG *** findings may pave the way for the development of innovative nanostructured scaffolds for BTE.
