Abstract This longitudinal investigation evaluated parental cultural socialization practices as a central mechanism by which parents' cultural values influence developmental outcomes in ethnic–racial minority children. Drawing on a sample of 129 Latina mothers and their children (48.1% daughters and 51.9% sons), path analyses evaluated hypothesized ...

通过对黄前库区流域森林主要类型刺槐林和油松林土壤结构状况和渗透性能的比较,研究了不同森林类型地表径流水的移动规律。在自然降雨后,以1m×1m为基本单位推算其可能产生的地表径流量,根据实际径流量推算地表径流水在径流过程中下渗的数量。研究结果表明:刺槐林的森林土壤结构相对较好,地表径流水下渗的速度较快,而流速较慢,因而产生的地表径流量较少;而油松林,特别是阳坡油松林的土壤结构较差,地表径流水下渗的速度较慢,而流速较快,因而产生的地表径流量较大。

Recovering Critical Elements From Wastewater for Battery Materials: A Review
ABSTRACT Driven by global carbon neutrality goals, the transition toward a circular economy and sustainable resource management has become increasingly imperative. Given the indispensable role of battery technologies in modern energy storage systems, strategic elements such as lithium (Li), cobalt (Co), and nickel (Ni)—identified by the European ...

为了研究水源地上游林地产流及其氮磷运移规律,采用人工模拟次降雨试验方法,选择鲁中南山区泰安市黄前水库上游药乡小流域赤松林地作为研究对象,以荒草地为对照,对其地表径流和壤中流及其氮磷流失特征进行研究。结果表明:(1)次降雨条件下赤松林地地表径流量低于荒草地,而荒草地壤中流量低于赤松林地,赤松林地及荒草地土壤入渗量与植被覆盖度呈正相关。随着降雨的进行,赤松林地和荒草地地表径流产流量不断增加且趋于稳定,壤中流产流时间比地表径流晚,径流量较平稳。(2)次降雨条件下地表径流全氮(TN)流失量呈现初期输出浓度较高 ...

ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves

Structural Modulation of Magnetic Softness in Fe‐Based Amorphous Alloys via Pulse Current Training
ABSTRACT Fe‐based amorphous alloys, despite their intrinsically low magnetocrystalline anisotropy, suffer from quasi‐dislocation dipoles and localized stress fields that impede domain‐wall motion and increase coercivity. Here, we introduce pulse current training (PCT) as an energy‐efficient technique to overcome these limitations in a Fe76Si9B10P5 ...

Two decades of changes in the global network of illegal wildlife trade
Abstract Understanding how illegal wildlife trade (IWT) has changed over time is fundamental for biodiversity conservation; however, knowledge of the network remains limited. We used TRAFFIC's IWT dataset, legal trade data from the CITES legal wildlife trade database as a benchmark, and network analysis to identify changes in IWT from 2000 to 2022. The

通过具有壤中流观测功能的径流小区的定位观测,结合人工降雨模拟试验,对常规施肥条件下紫色土坡耕地径流特征、过程及影响因素进行长期监测。结果表明:(1)紫色土坡耕地地表径流过程呈多峰特征,受瞬时雨强的影响明显;而壤中流过程则表现出明显的单峰、产流时间滞后、持续时间长等特点;(2)玉米灌浆成熟-收割期径流量明显高于其它生育期,地表径流、壤中流径流量分别为(65.06±5.94)mm,(86.36±3.27)mm,分别占3年地表径流、壤中流年均径流量的67.92%,79.82%;(3 ...
