Nickel laterite concentration through a non-conventional method with surface sulfidization

Dyna, 2020
Nickel ores are found mainly as sulfides and laterites in oxidized ores, such as iron oxides, which are usually “Ni-bearing”. This investigation determined the physical-chemical conditions necessary to increase the tenor and recovery in lateritic ...

Study on Macroscopic and Mesoscopic Mechanical Behavior of CSG based on Inversion of Mesoscopic Material Parameters

Science and Engineering of Composite Materials, 2020
Cement Sand and Gravel (CSG) is a low-cost, environment-friendly composite material mixed of unscreened aggregate, cement, fly ash and water, and its properties differ from ordinary concrete due to different aggregate characteristics.

Semisimple Rings Graded by Inverse Semigroups

Journal of Algebra, 1998
Let \(S\) be an inverse semigroup, and let \(R=\bigoplus_{s\in S}R_s\) be a faithful \(S\)-graded ring. If all group-graded subrings \(R_G=\bigoplus_{s\in G}R_s\) are semiprimitive (semiprime) for all maximal subgroups \(G\) of \(S\), then \(R\) is semiprimitive (semiprime).

Phase Angle as an Early Functional Biomarker of Cancer‐Related Fatigue in Pediatric Oncology: A Prospective Longitudinal Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric cancer remains a leading cause of morbidity and mortality worldwide, particularly in low‐and middle‐income countries. Cancer treatment may impair nutritional status, alter body composition, and exacerbate cancer‐related fatigue (CRF).

Inverse Grading Emerges From Particle‐Scale Migration Under Seasonal Freeze‐Thaw Forcing: Evidence From Multi‐Year Monitoring and Physical Modeling

Geophysical Research Letters
Inverse grading, where coarse particles overlay finer materials, is common on talus slopes, yet its progressive formation under realistic conditions is rarely quantified.

The Potential of PD-1 and PD-L1 as Prognostic and Predictive Biomarkers in Colorectal Adenocarcinoma Based on TILs Grading

Current Oncology
Aim: Colorectal cancer (CRC) is a prevalent malignancy with a high mortality rate. Tumor-infiltrating lymphocytes (TILs) play a crucial role in the immune response against tumors.

On Hierarchical Composite Endpoints in Pediatric Cancer Supportive Care: Illustrative Examples From Two Multi‐Center Phase‐III Randomized Clinical Trials

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric supportive care clinical trials often involve multiple clinically important outcomes, complicating trial interpretation. Hierarchical composite endpoints (HCEs) provide a framework to integrate key outcomes according to clinical importance.

Neogenin expression is inversely associated with breast cancer grade in ex vivo [PDF]

World Journal of Surgical Oncology, 2014
Neogenin is closely related to the human tumor suppressor gene deleted in colorectal cancer and plays a role in mammary morphogenesis. This study aimed to assess neogenin expression in breast cancer for any clinically significant association.A total of 54 breast cancer patients who underwent modified radical mastectomy were enrolled for ...

Secretory Phospholipase A2 in Patients With Sickle Cell Disease Hospitalized for Vaso‐Occlusive Pain Episodes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Secretory phospholipase A2 (sPLA2) is an inflammatory mediator linked to acute chest syndrome (ACS) in sickle cell disease (SCD), a serious complication that can develop during an acute vaso‐occlusive pain episode (VOE). Plasma sPLA2 levels have been proposed as a potential biomarker for predicting ACS onset.
