To determine appropriate quantities of water and fertilizer required for early growth of hybrid poplar cuttings,we recorded the growth traits of four clones grown under four factors(irrigation and nitrogen,phosphorus,and potassium fertilizers),each with four levels,using an orthogonal experimental design.A logistic model was used to estimate growth in *** growth curves for tree height were sigmoid,and the model R^2 values were greater than 0.9,which indicated that the fit was highly *** results for tree height and basal diameter indicated that all sources of variance showed significant differences(p<0.001).The average tree height and basal diameter for all the four clones under the different treatments ranged from 155.39 to 235.04 cm,and from 13.71 to 17.42 mm,respectively.A highly positive correlation between the extreme k value and tree height was observed,suggesting that the k value was an accurate estimation of tree *** model parameters,the earliest average time point for the onset of the rapid growth period of poplar clones was 131 d,and the highest average increment in tree height during the rapid growth period was 138.78 *** highest average tree height for all clones under each factor was 219,210.51,200,and 201 cm when treated with either 1200 mL of water applied every third day,3 g of nitrogen,0 g of phosphorus,or 0 g of potassium,*** most suitable treatment for the early growth of hybrid poplar cuttings,as suggested by the developed logistic model,was 1200 mL of water applied every third day and three applications of 1 g nitrogen(in the form of CH4N2O).

Background: Diabetes mellitus (DM) challenges health and quality of life of patients, families, and communities. Patients with comorbid depression are more likely to develop macrovascular and microvascular complications. The aim was to assess glycemic control and adherence in diabetic patients with comorbid depression. Further, the study evaluated the relationship between adherence and the physician-patient relationship. Methods: The study was conducted at Al-Agouza Family Medicine Center (AFMC) between February 2018 and March 2020. The included patients were between 35 - 80 years of age;had type 2 diabetes with hemoglobin A1c (HbA1c) ≥ 6.5%, fasting plasma glucose ≥ 126 mg/dl, and scored between 11 - 30 on the Beck Depression Inventory (BDI). Logistic regression, chi-square, and analysis of variance (ANOVA) were used to assess the relationship between depression, adherence, physician-patient relationship, and other variables. Results: The study included 100 eligible patients with a median BDI score of 20 (10 - 30). The median diabetic panel for patients was FBS 188 (126 - 348) mg/dl, PPS 282.50 (162 - 448) mg/dl, and HbA1c 9.5 (6.6 - 14.0)%. Depression and regular follow-up visits were statistically associated with improvement of diabetes symptoms (p = 0.019). There was a significant relationship (p 0.001) between adherence, regular follow-up visits, and knowledge of DM. Further, there was a significant relationship between the physician-patient relationship and DM improvement (p = 0.047). Conclusion: Physician-patient relationship was paramount to improving adherence and positive diabetes care. Our findings suggest a shift to a physician-patient relationship model with mutual agreement on medical decisions is highly recommended.

Compact toroidal magnetized plasmas are an important part of the world’s magnetic fusion and plasma science efforts. These devices can play an integral role in the development of magnetic fusion as a viable commercial energy source, and in our understanding of plasma instabilities, particle and energy transport, and magnetic field transport. In this paper, we are developing a numerical program to study the magnetic dynamo or relaxation of CT’s characterized by arbitrary tight aspect ratio (major to minor radii of tokamak) and arbitrary cross-sections (Multi-pinch and D-Shaped). The lowest ZFE’s has been calculated through the Taylor’s relaxed state (force-free) toroidal plasmas equation. For ZFE’s, we use the toroidal flux vanishing boundary condition along the whole boundary of tokamaks. Several runs of the program for various wave numbers showed that ZFE was very insensitive to the choice of wave numbers. Besides, the CT’s poloidal magnetic field topologies are well represented. It was very interesting to check our methods for the cases when aspect ratio tends to unity (zero tokamak whole). A good fulfillment of the boundary condition is achieved.

The excitation, growing and damping of current instability is an important and vital subject for a lot of studies through its importance in communication for instance and in understanding the nature of space and the interpretation of many phenomena in space and astrophysics. Recent analytical and numerical works are presented to describe and investigate the excitation and growing of kinetic electron-ion two streams instability in anisotropic inhomogeneous dusty space plasmas. We elucidated the thermal effects of plasma species on the characteristics of such instability. It is found that the gradient of space plasma temperature, , is a cause of interesting physical phenomena. Besides, different parameters, such as electron to ion temperature ratio , magnetized plasma and dust grains, are also found to play a crucial role in the growth and depression of such instability.

Recent theoretical work on electron beam heating of magneto-active motional Plasma is presented. Power transfer from beam (plasma heating) and generated electric fields for different physical situations of linear and nonlinear beam-plasma interaction, are studied. Based on previous works [1] [2], we shall study the effects of dusts and plasma motion () on plasma heating. Besides, the case of an inhomogeneity of beam velocity () is also considered. Taking into consideration nonlinear process, dust, plasma motion, and beam velocity inhomogeneity, are found to play a crucial role via power absorbed by the beam and the generated electric field in the system.
