In advanced traditional Chinese kung fu (martial arts), Neijing (Traditional Chinese: 內勁; pinyin: nèijìng) refers to the conscious control of the practitioner's qi, or "life energy", to gain advantages in combat.[1] Nèijìng is developed by using "Neigong" (Traditional Chinese: 內功; pinyin: nèigōng) (內功), or "internal exercises," as opposed to "wàigōng" (外功), "external exercises."

Much research and investigation has been carried out aimed at lithium recovery from brine. Although the distribution and occurrence status of lithium in brine have important implications for lithium recovery, few reports had correlated to this issue. In this article, a study was carried out to explore the lithium migration behavior during brine evaporation and KCl production process at Qarhan Salt Lake. The occurrence status of lithium both in fresh mined brine and residual brine after evaporation were also speculated by means of lithium concentration evaluation and theoretical calculation based on the Pitzer electrolyte solution theory. Results showed that, for Qarhan brine mined from the Bieletan region, most lithium was enriched in the residual brine during the brine evaporation process. The concentration of lithium in the residual brine could be more than 400 mg/L. More than 99.93% lithium ions in residual brine exist in free ions state and lithium does not precipitate from brine with a density of 1.3649 g/mL. The results also revealed that lithium concentration in wastewater discharged from KCl plants can reach a level of 243.8 mg/L. The investigation results provide a theoretical basis for comprehensive development and utilization of lithium resources in Qarhan Salt Lake. Keywords: lithium migration; occurrence status; Qarhan Salt Lake 1. Introduction As an energy metal of the twenty-first century, lithium had attracted more and more attention in the past few decades. Lithium has been widely applied in high energy batteries, controlled thermonuclear reactions, the manufacturing of ceramic and glass, and other fields [1–7]. Lithium consumption for batteries had increased most significantly due to the development of the electric vehicle industry and the popularity of portable electronic products. Stimulated by the political affairs, economic requirements, and environmental conservation, lithium resources have become the focus of the international mining market and lithium’s position as a strategic resource is becoming more prominent. Salt lake brine, thermal spring, and oilfield water are important geological sources of lithium. The commercial exploitation of the lithium resource of brine began at the Searles Lake in the US in 1936. Since then, more focus has been placed on recovering lithium from salt lake brine because of its low economical cost and low environmental impact [8–10]. As a country possessing huge amount of
Local field potentials (LFPs) were recorded from iPSC-derived motor neurons on days 17–21 in culture in 6-well multielectrode chips (9 electrodes and 1 ground per well) using a MultiChannel Systems MEA-2100 multielectrode array (MEA) amplifier (ALA Scientific) with built-in heating elements set to 37°C. Cells were allowed to acclimate for 5 minutes after chips were placed into the MEA amplifier, and after glutamate addition (10 μM final concentration). For 1 μM Apilimod treatments, chips were incubated for 35 min in a humidified incubator in the presence of the particular drug, then returned to the MEA amplifier and acclimated for 5 min before beginning recordings. For each condition, recordings (5 min baseline, 10 min glutamate and/or drug, 40 kHz sampling rate) were filtered between 1–500 Hz, and average LFP frequency per well was determined using the accompanying MC Rack software.
The Li force is observable when it is employed. Unlike the Li force, Neijing is said to be invisible. The "pivot point" essential to Li combat is not necessary in Neijing. At the point of attack, one must ‘song’ (loosen) himself to generate all Neijing energy one possesses and direct this energy stream through one's contact point with an opponent.[5] The contact point only represents the gateway to conduct Neijing energy at the point of attack.[6]

Journalistic genres in China have acquired distinctive characteristics and have shaped original sub-genres that are unique to the local journalistic tradition. While many studies analyzing their characteristics have been written in Chinese, works on the subject in other languages are still scarce. This contribution aims to fill this void by presenting the two main genres in which written journalistic production can be understood, i.e., “news” and “views”, as well as their sub-genres, and showing how they are interpreted in Chinese media studies. The analysis is based on a corpus of recent academic publications that represent the current Chinese scholarly interpretations of local genres of journalism. In doing so, the paper also offers insights on recent theoretical reflections about the functions of journalistic writing in the People’s Republic of China.
Samples were first fixed in 4% PFA (1x PBS) overnight at 4°C and were subsequently washed three times with 1x PBS. Next, cells were permeabilized with 0.3% Triton X-100 (1x PBS) for 10 min at room temperature, followed by three washes with 1x PBS for 10 min each. After permeabilization, the samples were equilibrated in 1x SSC buffer for 10 min at room temperature and then transferred into 50% formamide (2x SSC) for 10 min at 60°C. The repeat expansion-targeting probe and the negative control probe were ordered from Exiqon 58. During this step, the probe mixture (1µl salmon sperm (10 µg/µl), 0.5 µl E. coli tRNA (20 µg/µl), 0.4 µl probe (25 µM), 25 µl 80% formamide/per sample) was made and placed at 95°C for at least 10 min. The samples were submerged in 200 µl of hybridization buffer (4ml 100% formamide, 0.5 ml 20x SSC, 1 ml BSA fraction V, 0.5ml RVC (20 mM), 1ml NaPO4 (0.1 M), 3 ml nuclease-free water) and 27 µl of the probe mixture was added to each sample and incubated for 1 hour at 60°C. After probe hybridization, the samples were washed twice with 50% formamide (2x SSC) for 20 min each at 65°C and once more with 40% formamide (1x SSC) for 10 min at 60°C. The remaining formamide was removed by briefly washing with 1x SSC three times. A final crosslinking step was performed by first incubating the samples with 1x Tris-Glycine for 5 minutes followed by a 5 min incubation in 4% PFA. Samples were washed three times with 1x PBS, stained with DAPI, and imaged using a Zeiss LSM 800 confocal microscope.

With the four components of a chemical heat pump (two solid-gas reactors, an evaporator and a condenser), a cycle of the double-effect type can be applied to continuous refrigeration. The performance of this process is analysed, allowing the infinite sink temperature and the couples of reactive salts to be used, which depend on the production temperature envisaged, to be selected. The results are ... [Show full abstract]Read more

Immunostaining revealed that C9ORF72+/− and C9ORF72−/− iMNs contained elevated levels of NMDA (NR1) and AMPA (GLUR1) receptors on neurites and dendritic spines compared to control iMNs under basal conditions (Fig. 4a, c, d and Supplementary Fig. 5b and 10a, c-e, g, h, j, k). In addition, control iMNs treated with C9ORF72-specific ASOs displayed increased numbers of NMDA and AMPA receptors in their neurites (Supplementary Fig. 10l, m). C9ORF72 patient iMNs (n=3 patients) also showed elevated NR1 and GLUR1 levels compared to controls (n=3 controls), and forced expression of C9ORF72 isoform B reduced glutamate receptor levels in patient iMNs (n=3 patients) to that of controls (n=3 controls) (Fig. 4a-c and Supplementary Fig. 10a-h). mRNA levels of NR1 (GRIN1) and GLUR1 (GRIA1) were not elevated in flow-purified C9ORF72+/− iMNs, indicating that increased transcription could not explain the increased glutamate receptor levels (Supplementary Fig. 10n).
