Preparation of manganese oxide modified molecular sieve and its application in the treatment of phenol containing wastewater

上海师范大学学报. 自然科学版, 2021
An environmentally safe manganese oxide (MnOx) modified molecular sieve (MnOx@MS) for the effective treatment of phenol containing wastewater was prepared via an in situ oxidation of manganese sulfate(MnSO4)on the surface of 4A molecular sieve with ...

Image analysis of papaya seeds submitted to sarcotesta removal methods

Pesquisa Agropecuária Tropical, 2018
The germination of papaya seeds is slow and uneven, usually due to inhibitors present in the sarcotesta; however, some removal procedures may cause physical damage, negatively interfering in the physiological quality and field performance.

Prime Numbers Sieving - a Systematic Review with Performance Analysis

Algorithms, 2023
The systematic generation of prime numbers has been almost ignored since the 1990s, when most of the IT research resources related to prime numbers migrated to studies on the use of very large primes for cryptography, and little effort was made to further the knowledge regarding techniques like sieving.

Isotope (¹⁴C and ¹³C) analysis of deep peat CO₂ using a passive sampling technique [PDF]

, 2009
We developed and tested a new method to collect CO₂ from the surface to deep layers of a peatland for radiocarbon analysis. The method comprises two components: i) a probe equipped with a hydrophobic filter that allows entry of ...

Time- and Space-Efficient Evaluation of Some Hypergeometric Constants [PDF]

, 2007
The currently best known algorithms for the numerical evaluation of hypergeometric constants such as $\zeta(3)$ to $d$ decimal digits have time complexity $O(M(d) \log^2 d)$ and space complexity of $O(d \log d)$ or $O(d)$.

‘They Need to Hear You Say It’: Healthcare Professionals’ Perspectives on Barriers and Enablers to End‐of‐Life Discussions With Adolescents and Young Adults With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...

Development of a mass model in estimating weight-wise particle size distribution using digital image processing

International Journal of Mining Science and Technology, 2017
Particle size distribution of coarse aggregates through mechanical sieving gives results in terms of cumulative mass percent. But digital image processing generated size distribution of particles, while being fast and accurate, is often expressed in ...
