Fluxes, patterns and sources of phosphorus deposition in an urban-rural transition region in Southwest China

For estimating the global P biogeochemical cycle, understanding the patterns of atmospheric phosphorus deposition is critical. Preferred sources of P in agricultural production as well as eutrophication in waters are both important sources of P in aquatic activities, as well as eutrophication in waters; however, the reports on P deposition are less widely distributed, particularly in the anthropogenic influencing region. The fluxes of atmospheric total P deposition varied from 0. 50 to 1. 06 kg P yr-1, according to the study, and the primary form was atmospheric dry P deposition. However, the landscape and country road areas were more affected by land use, which increased with the agro-facility, town, and paddy field areas, but not so much with the woodland and country road areas. These results indicated that ADD was the most common type of ATD, and P deposition could be both affected by climate change and land use types.

Water salinity, nitrogen and phosphorus on photochemical efficiency and growth of west indian cherry

ABSTRACT This research was conducted to determine the relationship between water salinity and doses of nitrogen and phosphorus on chlorophyll a fluorescence and plant development in West Indian Cherry plants in the initial growth stage. Photosystem II's quantum yield and the production of west indian cherry plants declines by more than 2. 2 dS m-1. Increased nitrogen and/or phosphorus supply enhances the energy stability of west Indian cherry plants by minimizing the effects of salt stress on photosystem II's quantum efficiency.

Synthesis, Structural, Viscosimetric, And Rheological Study, of A New Trifunctional Phosphorus Epoxyde Prepolymer , Tri-Glycidyl Ether Tri-Mercaptoethanol Of Phosphore (TGETMEP)

In two stages, the aim of our research is to synthesize a new phosphorus tri-functional epoxy resin tri-mercaptoethanol of phosphorus. We found that with epichlorohydrin, we could have obtained the synthesis of tri-functional resin TMEP condensation. On one hand, the standard TGETMEP resin was distinguished by Fourier's infrared transformation and nuclear magnetic resonance.

Correlation between serum dosage of Calcium, Phosphorus, Alkaline Phosphatase and epifisary closing age in foals of low genetic grouping / Correlação entre as dosagens séricas de Cálcio, Fósforo, fosfatase Alcalina e idade de fechamento epifisário em potros do grupamento genético baixadeiro

In the dry season, Maranhu00e3o's submerged area is characterized by its unique ecosystem, flooded fields in rainy seasons, and an arid climate. In craniocaudal projection, the radiographic process used was 53 kVp and 5 mAs with a film focus distance of 70 cm. Blood samples were collected by puncture of the external jugular vein and stored in Ependorff tubes, frozen until processing. According to the findings, the average age of closure of the growth plate was 26. 7 months for males and 24. 5 for females. As for serum dosages, we discovered that male average values were higher in calcium, while female average values for both phosphorus and alkaline phosphatase were higher in females.

Quantitative trait loci analysis of root traits under phosphorus deficiency at the seedling stage in wheat

In a recombinant inbred line population of Triticum aestivum L. at the seedling stage, we investigated five root characteristics under hydroponic culture conditions, with or without applied P. The diversity array technology markers flanking the QTL were converted to simple sequence repeat markers that could be used in future genetic studies of P deficiency. These QTL lead to an increase in root biomass and response to P-deficiency stress, as these characteristics are essential to improve root traits for breeding or further testing of the gene responsible for P-deficiency tolerance.

Interaction Effect of Phosphorus and Boron on Yield Components, Productivity Parameters and Quality Traits of Lentil (Lens culinaris L.)

In the C. A. R. 's Rabi season, 2021-22, a field trial was held on sandy loam soil with low quality of organic carbon and readily available nitrogen, medium in accessible phosphorous, and high in accessible potassium at Pot house of Department of Soil Science and Agricultural Chemistry of C. A. U. A. C. A&T's Kanpur under the Indo-Gangetic Plain zone of Uttar Pradesh. It may be concluded that the application of 60 kg P2O5 ha-1+ 2. 5 kg Boron ha-1 produced high yield values viz. vid. (Japan) on the basis of the comes about investigation, which was excluded from the present investigation. Maximum protein content and protein yield was also associated with the application of 60 kg P2O5 ha-1. The present study clearly shows the importance of balanced use of Phosphorus and Boron nutrients in Lentil for increasing yield components, yield, and quality of Lentil crop.

Interstitial radiotherapy using phosphorus-32 for giant posterior fossa cystic craniopharyngiomas

OBJECT The treatment of massive posterior fossa cystic craniopharyngiomas remains a significant obstacle in neurosurgery. The authors reviewed the results of treating 20 patients with massive posterior fossa cystic craniopharyngiomas at their hospital with phosphorus-32 interstitial radiotherapy at their hospital. RESULTS The treatment began immediately and reduced intracranial hypertension in all patients. During the follow-up period, 7 new cysts appeared in 5 patients who had undergone additional interstitial radiotherapies with a dose of P-32 that was calculated using the same formula as for the initial therapy. CONCLUSIONS & DESIGN CLINICS can be used to achieve a high tumor control rate, as well as quality of life outcomes with no complications.

Efficacy of phosphorus-32 brachytherapy without external-beam radiation for long-term tumor control in patients with craniopharyngioma

OBJECT (OBJECT) ObJECTIVE phosphorus-32 has been used as brachytherapy for craniopharyngiomas with the intention of delivering local control of enlarging tumor cyst cysts. Brochytherapy may produce local radiation that regulates or shrinks a symptomatic cyst without exposing the patient to EBR risks. The authors reviewed their experiences with craniopharyngioma patients treated with P32 brachytherapy as the primary therapy without EBR in this research. METHODS The authors conducted a retrospective review of pediatric patients treated for craniopharyngioma between 1997 and 2004. All patients who underwent emergency and injection of P32 without an EBR were identified. RESULTS Thirty-eight patients were treated for craniopharyngioma during the study period. Nine patients were found who underwent radiotherapy with P32 brachytherapy, but no one had an initial EBR. Patients with cancer growth required repeat EBR for tumor formation. P32 injections were followed by 1. 67 years u00b1 1. 50 years b. 2. 50 years b. a.
