The study, conducted at the Research Farm of the College of Agriculture, University of Tabriz in 2021, focused on the effects of various nitrogen-fixing bacterial isolates, biofertilizers containing nitrogen and phosphorus, as well as iron and zinc foliar applications on mustard growth under rainfed conditions. The results indicated that biofertilizers, whether used alone or in combination with chemical fertilizers, produced comparable grain and oil outputs compared to chemical fertilizers alone. Additionally, the application of iron and zinc through foliar spraying significantly enhanced both grain and oil production. These findings suggest that integrating nitrogen-fixing bacteria and biofertilizers could reduce reliance on chemical nitrogenous fertilizers, leading to decreased production expenses, improved product quality, and minimized environmental impact. This study highlights the potential for sustainable agricultural practices in dry land farming as a viable alternative to traditional chemical-intensive methods. Substituting chemical nitrogenous fertilizers with nitrogen-fixing bacteria or biofertilizers could result in cost savings in mustard grain and oil production while promoting environmental sustainability. 展开更多

[ Objective] The aim of the research was to provide reference for reasonable application of nitrogen fertilizer for high yield.cultivation of hybrid rape cuhivar Youyan 9 and Youyan 10. [ Method] The net increment changes of individual plant fresh weight and dry matter weight of Youyan 9 and Youyan 10 with different nitrogen application treatments were studied. [ Result] The differences among average fresh weight increments of individual plant and average dry matter weight increment of individual plant with different treatments reached 0. 01 extremely significant level. Fresh weight increment and dry matter weight net increment of individual plant declined gradually with the increase of nitrogen application. In growtheourse ,fresh weight net increment of individual plant increased firstly then decreased and the maximum was in beginning flowering stage, besides that dry matter net increment increased gradually and the maximum was in mature period. The correlations among fresh net increment, dry matter weight net increment and yield net increment were positive or extremely positive. [ Conclusion] Under experimental condition, when nitrogen application was 225 kg/hm^2, hybrid rape Yanyou 9 and Yanyou 10 with low erucic,low glucosinolate could obtain high yield. 展开更多

[Objective] The aim of the research was to find the optimal nitrogen application rate, density and seedling age for no-tillage rape in seedling stage. [Method] With the D-optimal quadratic regression design for three factors, the 310 scheme was designed to study the effects of nitrogen application rate, density and seedling age on dry matter accumulation of no-tillage rape in seedling stage. [Result] With the increase of nitrogen application rate, density and seedling age, the dry matter content appeared like a parabola, increasing firstly and then declining. The change of nitrogen application rate caused greater influence than that of density and seedling age; the interaction effects between nitrogen application rate and density were greater than that between nitrogen application rate and seedling age as well as between density and seedling age. [Conclusion] Considered comprehensively, the dry matter content of no-tillage rape in seedling stage reached the highest level (4 768.2 kg/hm2) when the nitrogen application rate, the density and the seedling age were 195 kg/hm2, 93 000 plants/hm2 and 33 d, respectively. 展开更多

The effects of calcium application rate on dry matter accumulation and yield of peanut were studied under high-yielding field condition. The variety used for the study was Tang A8252( Spanish peanut). The results showed that number of full fruit,dry weight per plant,kernel yield,and pod yield all increased with calcium application increased,and they decreased when calcium application rate was more than150 kg/ha. Both the height of main stem and the length of side shoot decreased with calcium application increased. Therefore,to obtain the optimal agronomic character index and the highest yield benefit,the suggested calcium application rate would be 150 kg/ha for peanut. 展开更多

Dry season water application and conservation were studied for two years in Ado Ekiti to evaluate their effects on the performance of plantain Musa spp.. The treatments were: morning watering (MW), evening watering (EW), morning and evening watering (MEW), morning watering + mulch (MW + ML), evening watering + mulch (EW + ML), morning and evening watering + mulch (MEW + ML), mulch (ML) and Control. Height and girth increase, number of green leaves, yield and yield parameters were the highest in the MEW + ML which were identical to those of Evening watering + mulch and morning + evening watering. The evening or morning watering with mulch was identical but showed better performance than those without mulch. The mulched plants and the control showed the least performance. It is therefore recommended that proper water conservation in plantain plantation will improve banana survival during dry season and subsequently increase yield in the study area. 展开更多

OBJECTIVE: To study the clinical comparison and analysis of decoction of Traditional Chinese Medicine(TCM) combined with ear acupoint application and simple artificial tears in the treatment of dry eye syndrome. METHODS:A total of 62 patients(124 eyes) with dry eye syndrome treated in the Department of Ophthalmology of The 4th People's Hospital of Shenyang from July 2017 to March 2018 were selected and equally divided into 2 groups according to the admission order. The observation group received the combination therapy of TCM decoction and ear acupoint application, while the control group was given the simple artificial tears. The symptom score after 2 weeks, 4 weeks, and 8 weeks as well as the indicators including break-up time(BUT), Schirmer I test(SIT) and fluorescein(FL) were recorded and compared between groups. RESULTS: The symptom scores had no difference before treatment(P > 0.05), and were better in the observation group than those in the control group after treatment(P < 0.05). At 2 weeks, 4 weeks, and 8 weeks after the treatment, the amelioration level of BUT, SIT, and FL indicators in the observation group was better than that of the control group(P < 0.05). CONCLUSION: Compared with the artificial tears treatment method, the TCM decoction combined with ear acupoint application can significantly ameliorate the tear film stability, tear secretion, and reduce ocular surface damage for dry eye patients. 展开更多

[Objective] To understand the effect of nitrogen application on dry matter accumulation and allocation dynamics in broomcorn millet. [Method] The accumulation and distribution of dry matter were studied using cultivars Jin Shu 7 and Huang Mizi at different levels of nitrogen fertilizer at the jointing stage. [Result] The results showed that increasing N application led to the increase of green leaf area and the delay of leaf senescence, which was beneficial to the accumulation of dry matter.Appropriate nitrogen application(90 kg/hm2) could coordinate the translocation rate of dry matter among different plant parts, thereby enhancing the yield of broomcorn millet; among different organs, the contribution rate of stem to kernel was greater than that of leaf to kernel; there was obvious correlation between dry matter and yield. For Jin Shu 7, leaf area and dry weight of spike showed significant negative correlation with yield. [Conclusion] The formation of grain yield of broomcorn millet involved the accumulation and allocation of dry matter, the appropriate amount of nitrogen application(90 kg/hm2) could improve the rates of translocation and contribution of dry matter, thereby promoting the yield of broomcorn millet. 展开更多

Cefuroxime axetil(CA)is an ester prodrug of cefuroxime with an unpleasant taste when administrated orally.This work was to mask the bitter taste of CA and enhance its oral bioavailability.Dry suspensions were prepared by means of wet granulation method and solid dispersion method.Binders,suspending agents and other compositions involved in the formulation were optimized.The differential scanning calorimetry(DSC)analysis indicated that CA was amorphous in the solid dispersion with stearic acid as the carrier,which contributed to an improvement of the dissolution rate.Taste evaluation was performed by three volunteers and taste masking was successfully achieved by the methods mentioned above.A pH 7.0 phosphate buffer was adopted to study the in vitro dissolution performance of the three formulations,i.e.,two self-made dry suspensions and the commercial one.With a better release characteristic and a satisfying taste masking ability,the solid dispersion suspension was selected as the optimal formulation for the further pharmacokinetic study in beagle dogs.The values of Cmax and AUC0e12 for the solid dispersion suspension were about 1.78-fold and 2.17-fold higher than these of reference suspension,respectively.The obtained results demonstrated that the solid dispersion can efficiently mask the bitter taste of CA and significantly enhance its oral bioavailability. 展开更多

The synthesis of mesoporous zeolite-anchored atomically dispersed metal catalysts(ADCs)is a considerable challenge in chemistry and materials science.Here we report the synthesis of atomically dispersed cationic nickel-confined mesoporous ZSM-48(ANMZ-48)by in situ hydrothermal reaction employing a designed tri-functional metal complex template,by which the triquaternary ammonium groups in the hydrophilic region direct the formation of ZSM-48 zeolite;the aromatic groups in the hydrophobic tail generate the mesopores through π-π stacking;and the complexes formed by nickel ions coordinated with terpyridyl groups generate atomically dispersed Ni2+confined in zeolite frameworks due to the strong sintering resistance generated by the strong coordination interaction.The ANMZ-48 is consisting of stacking of sheet-like ZSM-48 domains connected by multiply crystal twinning sharing the common(011)plane,generating abundant of imbedded mesopores with the uniform thickness of~2.4 nm and with the width of 10-50 nm.The excellent catalytic activity and stability of ANMZ-48 were also reflected in the dry reforming of methane(DRM)reaction. 展开更多

Particle coatings are used extensively to generate dispersed solids with well-defined properties, e.g., to protect active ingredients, with most coating processes using core particles of a diameter larger than 200 μm. This work contributes to the development of a coating process for fine dispersed particles (diam- eter less than 50 μm) by combining two particle-formulation processes, namely, coating and spray drying. The feasibility of the operation is based on and demonstrated by the innovative application of a two-fluid nozzle. Experiments were conducted by using glass particles as core particles and sodium benzoate as the coating agent. The coating of finely dispersed particles is achieved by the spraying of particles and coating solution as a homogeneous suspension. The aim is to create droplets with only one contained particle at the nozzle outlet. After evaporation of the water in the droplet, a thin solid film is built on the particle surface. The suspension viscosity was measured and compared with empirical equations from the literature. The liquid-film thickness on the particle surface was calculated to predict the building of a uniform coating layer or agglomerates. In this study, the feasibility of pneumatic transport through the nozzle and an investigation of the process were illustrated. The agglomeration fraction and degree of coating of the particle surface were analyzed optically by scanning electron microscopy. In this way, the influence of different processes and suspension parameters on the product quality were determined. 展开更多

Air flow and particle-particle/wall impacts are considered as two primary dispersion mechanisms for dry powder inhalers(DPIs).Hence,an understanding of these mechanisms is critical for the development of DPIs.In this study,a coupled DEM-CFD(discrete element method-computational fluid dynamics)is employed to investigate the influence of air flow on the dispersion performance of the carrier-based DPI formulations.A carrier-based agglomerate is initially formed and then dispersed in a uniformed air flow.It is found that air flow can drag API particles away from the carrier and those in the downstream air flow regions are prone to be dispersed.Furthermore,the influence of the air velocity and work of adhesion are also examined.It is shown that the dispersion number(i.e.,the number of API particles detached from the carrier)increases with increasing air velocity,and decreases with increasing the work of adhesion,indicating that the DPI performance is controlled by the balance of the removal and adhesive forces.It is also shown that the cumulative Weibull distribution function can be used to describe the DPI performance,which is governed by the ratio of the fluid drag force to the pull-off force. 展开更多

The aggregation of inorganic particles with high mass ratio will form a heterogeneous electric field in the solid polymer electrolytes(SPEs),which is difficult to be compatible with lithium anode,leading to inadequate ionic conductivity.Herein,a facile spray drying method is adopted to increase the mass ratio of inorganic particles and solve the aggregation problems of fillers simultaneously.The polyvinylidene fluoride(PVDF)with lithium bis(trifluoromethanesulfonyl)imide(LiTFSI)covers the surface of each Li_(6.4)La_(3)Zr_(1.4)Ta_(0.6)O_(12)(LLZTO)granules during the nebulization process,then forming flat solid electrolytes via layer-by-layer deposition.Characterized by the atomic force microscope,the obtained solid electrolytes achieve a homogenous dispersion of Young’s modulus and surface electric field.As a result,the as-prepared SPEs present high tensile strength of 7.1 MPa,high ionic conductivity of 1.86×10^(−4)S·cm^(−1)at room temperature,and wide electrochemical window up to 5.0 V,demonstrating increased mechanical strength and uniform lithium-ion migration channels for SPEs.Thanks to the as-prepared SPEs,the lithiumsymmetrical cells show a highly stable Li plating/stripping cycling for over 1,000 h at 0.1 mA·cm^(−2).The corresponding Li/LCoO_(2)batteries also present good rate capability and excellent cyclic performance with capacity retention of 80%after 100 cycles at room temperature. 展开更多
