Survey of Framer Credit Demands in China with Tianjin as an Example

Giving farmers more rights and interests on land property is the basis of achieving balanced and coordinated economic development between urban and rural areas as well as building a sharing economy during the period of economic transition in China.Based on the survey data of suburban households of Tianjin,in this paper,measurement method was adopted to study factors influencing farmer s willingness on land management right mortgage.The results shows that the willingness of individual farmer on mortgage is not strong,however,their willingness on mortgage is bound to have a significant relationship with farmland right confirmation and land transfer and other factors.Finally,it is concluded that it is necessary to promote land transfer on the basis of land right of confirmation while carrying out farmland mortgage under the premise of large-scale operation in China.

Functional Confirmation Using a Medical X-Ray System of a Semiconductor Survey Meter

In recent years, semiconductor survey meters have been developed and are in increasing demand worldwide. This study determined if it is possible to use the X-ray system installed in each medical facility to calculate the time constant of a semiconductor survey meter and confirm the meter’s function. An additional filter was attached to the medical X-ray system to satisfy the standards of N-60 to N-120, more copper plates were added as needed, and the first and second half-value layers were calculated to enable comparisons of the facility’s X-ray system quality with the N-60 to N-120 quality values. Next, we used a medical X-ray system to measure the leakage dose and calculate the time constant of the survey meter. The functionality of the meter was then checked and compared with the energy characteristics of the meter. The experimental results showed that it was possible to use a medical X-ray system to reproduce the N-60 to N-120 radiation quality values and to calculate the time constant from the measured results, assuming actual leakage dosimetry for that radiation quality. We also found that the calibration factor was equivalent to that of the energy characteristics of the survey meter.

Traditional Use of Medicinal Plants Confirmed by the Baka in Southern and Eastern Cameroon

The limitations of biomedecine to provide effective solutions to certain pandemics has led many people to turn to alternative therapies. These palliative solutions, particularly phytomedecines, are much sought after for disease prevention and treatment. The Baka, a group of forest-dwelling people, hold knowledge on how wild plants can be effective in treating many illnesses. However, the greatest challenge for the identification of traditional medicines depends on the veracity of the information provided during ethnobotanic surveys by user populations. The present study describes forest plants used by the Baka and confirmed by them as being employed for traditional medicine. We carried out ethnobotanical surveys between 2019 and 2021 in 221 households within four districts of the Eastern and Southern Region of Cameroon. We used indices of significant use and performance applied to all mentioned species, alongside searches in the literature. The statistical tools used to distinguish the different groups/districts is Pearson’s X2 test. A total of 378 plant species were identified of 270 genera and 85 families. Ethnobotanical indices allowed to identify the most confirmed and efficient plants for several health problems. A pairwise comparison of these indices showed a significant correlation with a p-value < 2.2e-16 and a dissimilarity distance less than 0.5. Some plants selected are widely cited in other regions and/or countries for the same health problems. The presence of active molecules responsible for their biological activity was also proven, justifying their use in traditional medicine. This paper examines the potential to enhance the value of Cameroon’s pharmacopeia by integrating various ethnobotanical indices. It aims to discover new therapeutic molecules and develop improved traditional products from the diverse plant species documented. The findings indicate opportunities to advance both local and global healthcare solutions.

The update of Zhejiang bird checklist

Complete checklist records are essential to understand regional bird diversity and the status of the distribution of birds. The Zhejiang bird checklist was last presented as the Aves Branch of Zhejiang Fauna in 1990. Since then, many new records had been added, of which most remain unpublished. We have collected and examined all published and unpublished new records from Zhejiang habitats as well as those from the Aves Branch of Zhejiang Fauna. We have confirmed the evidence of the new records, which includes specimens, photographs, videos, sounds and tissue samples. We changed the Latin names of 131 species and subspecies and 41 Chinese names according to the new taxonomy and nomenclature. We provide an updated Zhejiang bird checklist for a total of 483 species and 24 subspecies, including 70 new species records, of which 47 species are reported for the first. Most of the new records are based on recent photographs taken by bird watchers.

Objective:To investigate the long-term safety of a tetravalent dengue vaccine(CYD-TDV)in children in a phase Ⅱ b follow-up study in Thailand.Methods:In the phase Ⅱb study,children aged 4-11 years were randomized(2:1)to receive three injections of CYD-TDV or serve as control at 6-month intervals,with 25 months’ active follow-up(active phase).This study was an additional four-year passive surveillance for hospitalized virologically-confirmed dengue(VCD;hospital phase).Cases of hospitalized VCD,severe hospitalized VCD,vaccine-related serious adverse events,and deaths were reported for the total population,with post-hoc analyses by enrollment age(<9 and≥9 years).Results:Of 3 997 participants receiving≥1 injection,80.1% were recruited to the hospital phase[2 131(CYD-TDV);1 072(control)].Eighty-five hospitalized VCD cases were reported in the CYD-TDV group and 46 in the control group during the four-year hospital phase[relative risk(RR):0.93,95% confidence interval(Cl):0.64-1.36].The RR over six years of follow-up was 0.77(95% CI:0.57-1.05).In those aged≥9 years,the cumulative RRs in the active phase,hospital phase,and entire six years were 0.28(95% CI:0.08-0.81),0.51(95% CI:0.25-1.05),and 0.42(95% CI:0.24-0.75),respectively.In the overall population,there were ten severe hospitalized VCD cases in the CYD-TDV group and five in the control group over six years(RR:1.00,95% CI:0.31-3.75).Conclusions:Over six years of follow-up,in children aged ≥9 years,CYD-TDV administration is associated with a reduced risk of hospitalized VCD.

Determination of 8 Diuretics and Probenecid in Human Urine by Gas Chromatography-Mass Spectrometry: Confirmation Procedure

A fast and sensitive method for determination of 8 diuretics (acetazolamide, bendroflumethiazide, bumetanide, chlorthalidone, furosemide, hydrochlorothiazide, metolazone, triamterene) and masking agent (probenecid) in human urine using gas-chromatography with mass spectrometric detection is described. The extraction of the substances as function of the nature of organic solvent, mixing time and pH of aqueous phase was studied. The tandem mass spectrometry was used to increase selectivity of diuretics determination due to elimination of background interferences. Fragmentation reactions were studied for each compound and their collision energies were optimized to obtain the best selectivity. The results of method’s validation demonstrate its suitability in routine analysis for confirmation purposes.

Pear Blossom Blast Caused by Pseudomonas syringae pv. syringae in China

This study was done to determine the causal organism of the pear blossom and bud blast in China. It was identified by a bacteriological test, electro-microscopic observation, Koch＇s postulate test, Biolog, fatty acid methyl esters （FAMEs）, and a polymerase chain reaction （PCR） test, and compared with the standard reference strains. Six representative strains out of 20 pathogenic bacterial isolates from 16 diseased samples showed characteristics similar to three standard strains of Pseudomonas syringae pv. syringae from Belgium. They were identified as P. syringae pv. syringae with a Biolog similarity of 0.57-0.86 and FAMEs similarity of 0.58-0.81. The bacterium was reisolated from the symptomatic plants and blossoms. Identification as P. syringae pv. syringae was confirmed by using PCR primers and sequence tests, and compared with the above-mentioned results. The data supported the fact that the pear blossom and bud blast in China could be caused by P. syringae pv. syringae.

SONOGRAPHIC PATTERNS AND DIFFERENTIAL DIAGNOSIS OF CYSTIC RENAL CARCINOMAS

OBJECTIVE: To study the sonographic features and patterns of cystic renal carcinomas. METHODS: Thirteen cases of cystic renal carcinoma confirmed by operation and pathology were examined by ultrasonography, and the cystic walls, septa and solid mural nodules were studied. RESULTS: Solid mural nodules of some cases and irregular thickening of the cystic walls and septa were characteristic findings for the ultrasonic diagnosis of cystic renal carcinomas. According to their pathologic mechanisms and sonographic features, cystic renal carcinomas were classified into 3 patterns: unilocular cystic mass, multiloculated cystic mass and cystic-solid mass. CONCLUSIONS: Typical cystic renal carcinomas can be well diagnosed, while atypical cases may be misdiagnosed as benign renal cysts by ultrasonography. Color Doppler ultrasonography and needle aspiration guided by ultrasonography are helpful in the diagnosis of these atypical cases.

To introduce the epidemical, pathological, and clinical characteristics as well as the diagnostic and therapeutical experiences of endomyocardial fibrosis(EMF) in China. [WT5”BX] Data sources.[WT5”BZ]A CMBdisc search was done of the Chinese language literature published from January 1983 through June 1997 about EMF and/or restrictive cardiomyopathy. A manual search was then done for other contributions, including abstracts, between January 1965 and June 1997. [WT5”BX] Results. [WT5”BZ]Eighty seven Chinese cases of EMF were collected in this paper. There were 49 men and 38 women, with a mean age of 28±13 years(range, 8 to 68 years). The distribution of the cases is mainly in the south of China. Combined right and left ventricular disease occurs in 48 percent of cases, with pure right ventricular involvement occurring in 42 percent and pure left ventricular involvement in the remaining 10 percent of patients who are examined postmortem. The diagnosis of EMF was confirmed in 21 cases at autopsy, and in 66 cases by echocardiography, angiocardiography, and/or endomyocardial biopsy which showed the characteristic changes. Clinically, right sided disease is the commonest variety. Endocardiectomy and tricuspid(n=7) or mitral(n=1) valves replacement have been performed in 8 patients. There were 2 operative deaths. Six patients had a satisfactory recovery postoperatively and living well in the follow up duration. [WT5”BX] Conclusion.

The whole process confirmation management and its application in coal mine safe production

After analyzing the reasons for coal mine accidents and the current management methods, effective actions for the implementation of safety management were put forward by carrying out the whole process confirmation management. The ba- sic content and the five implementation steps were described, and the implementation method and the program of every step were introduced. Some rules for the implementation of the whole process confirmation management in coal mine safety pro- duction were explained, such as during the process of preproduction, before descent, descent, after descent, walking in the roadway, post-operation, shift, and hoisting after work. The results show that the guardians and the executors should both con- firm the implementation, which can improve the workers＇ attention and self-awareness to avoid errors in detail and reduce the ＂three violations＂ phenomenon. To ensure the effect of the whole process confirmation management, relevant departments should designate a person-in-charge in the specific work in all stages, make a work plan, and strengthen the internal evaluation.

Classical Quantum Field Theory Based on the Hypothesis of the Absolute Reference System

The quantum field theory based on the hypothesis of the absolute reference system is a classical non-relativistic theory, which is compatible with current quantum theory. This conclusion arises when one compares the theoretical results of quantum electrodynamics using the basic principles of this hypothesis. Wave equation, which replaces this of Schrodinger, is the classical wave equation of a peculiar electromagnetic wave, derived from the study of particle structure.
