Rapid Detection of Total Petroleum Hydrocarbons in Soil Using Advanced Fluorescence Imaging Techniques.

Chemical methods for measuring soil organic content are often slow and yield inaccurate results due to significant errors. Simple summation of components may not accurately determine total organic content. In contrast, fluorescence imaging techniques offer rapid, in situ monitoring without complex pretreatment and demonstrate rapid and accurate assessment of soil organic content.

Managing government debt.

To construct a stochastic version of [R. J. Barro, , 940-971 (1979)] normative model of tax rates and debt/GDP dynamics, we add risks and markets for trading them along lines suggested by [K.

Correction method of the fluorescence intensity of petroleum hydrocarbons in different soil types based on resonance scattering spectroscopy.

Soil types has an obvious impact influence on the fluorescence intensity of soil petroleum hydrocarbons. To reduce the interference caused by soil types, this paper proposes a calibration method using resonance scattering spectroscopy. To establish the correction method, 100 g/kg crude oil samples from six soil types were prepared.

B4GALNT1 promotes carcinogenesis by regulating epithelial-mesenchymal transition in hepatocellular carcinoma based on pan-cancer analysis.

Background: β-1,4-N-Acetyl galactosaminyltransferase1 (B4GALNT1) has been reported to play important roles in tumor progression and metastasis. Herein, we investigate the oncogenic roles of B4GALNT1 for hepatocellular carcinoma (HCC) based on immune microenvironment.

Methods: The Cancer Genome Atlas database and Genotype-Tissue Expression, cBioportal, ImmuCellAI, TIMER2 and other databases were searched to analyze the expression and clinical applications of B4GALNT1 in liver cancer patients.

Acoustic emission characteristics and damage evolution of basalt by microwave irradiation.

The microwave-assisted rock breaking technology has been proven to be feasible, and has received considerable attention in the field of civil and mining engineering. A copper foil was used to wrap basalt to simulate rock excavation of practical application scenario in this paper. To this end, a multi-mode cavity with an operating frequency of 2.

Network meta-analysis of deaths from various underlying diseases after COVID-19 infection.

Network meta-analysis of deaths from various underlying diseases after COVID-19 infection. This study included more than 10 research centers with the same level of care. In total, 1,676 subjects were included in our study, including 1,122 men and 554 women, patients diagnosed with COVID-19, and combined with underlying diseases; provided data on the number of deaths from related diseases, such as hypertension, diabetes, heart disease, cerebrovascular disease, malignant tumor, chronic kidney disease, chronic liver disease, and respiratory disease.

Comparison of PKRP and TUVP in the treatment of high-risk BPH and analysis of postoperative influencing factors.

Objective: This study aims to compare the efficacy of plasma kinetic loop resection of the prostate (PKRP) and transurethral vaporization of the prostate (TUVP) for the treatment of high-risk benign prostatic hyperplasia (BPH), and analyze the influence of the related factors on the operation of BPH.

Methods: A total of 108 high-risk BPH patients diagnosed in our hospital from March 2018 to September 2021 were selected and randomly divided into an observation group and a control group, with 54 cases in each group. The control group was treated with TUVP, and the observation group was treated with PKRP.

Tobin's and corporate investment with a pandemic shock.

We analyze the impact of COVID-19 on investment by incorporating a stochastic transmission shock into the standard theoretical framework. Our model suggests that the adjustment cost amplifies the negative pandemic shock to investment and decreases firm value. In particular, when the infection rate is low, the reduction in investment is higher for firms with low adjustment costs in that they are more sensitive to the infection rate.

A Report of 61 Cases of Retroperitoneal Laparoscopic Nephron-Sparing Surgery and Factors Affecting Postoperative Renal Function.

Objective: To explore the situation of 61 patients with renal tumors who underwent retroperitoneal laparoscopic nephron-sparing surgery (RLNSS) and the factors affecting postoperative renal function.

Methods: A total of 61 patients with renal tumors who underwent RLNSS in our hospital from January 2018 to January 2021 were included in this study. All patients were treated with RLNSS.

Efficacy of Etimicin Sulfate Combined with Cefotaxime Sodium in the Treatment of Patients with Septic Shock and Effect on Serum Inflammatory Factor Levels and Immune Function.

Objective: To explore the effect of etimicin sulfate combined with cefotaxime sodium and cefotaxime sodium alone in the treatment of patients with septic shock and the effect on serum inflammatory factor levels and immune function.

Methods: Total of 95 patients with septic shock who were treated in our hospital from March 2018 to July 2020 were collected as the subjects of this study. Among them, 44 patients who received cefotaxime sodium treatment and were included in the control group, and 51 patients who received etimicin sulfate combined with cefotaxime sodium treatment were included in the research group.

Earnings growth and the wealth distribution.

As measured by Gini coefficients, fractile inequalities, and tail power laws, wealth is distributed less equally across people than are labor earnings. We study how luck, attitudes that shape saving decisions, and growth rates of labor earnings balance each other in ways that simultaneously shape joint distributions across people of labor earnings, age, and wealth together with an equilibrium rate of return on savings that plays a pivotal role in balancing contending forces. Strong motives for people to save and for firms to demand capital raise an equilibrium interest rate enough to make wealth grow faster than labor earnings.

MicroRNA-30 mediates cell invasion and metastasis in breast cancer.

Despite the great progress in recent years, many aspects of the pathogenesis and progression of breast cancer remain unclear. A better understanding on the molecular mechanisms underlying metastasis and recurrence is crucial to improve the treatment of this lethal disease. MCF-7 cells were xenografted into mice until visible tumors developed, and the cells from tumor tissue and adjacent normal tissue were cultured with 3 passages as mass tumor (MT) cells and invasive tumor (IT) cells, respectively.

[Multi-index determination and optimization of liquirtin separated from polyamide resin].

To optimize the separation process of liquirtin from glycyrrhiz by static, dynamic adsorption and desorption experiments on polyamide resin, with liquirtin, isoliquiritin and glycyrrhizic acid as the study index. The optimum process conditions were that the pH of solution was regulated to be 7.0, the concentration of liquirtin was 1.
