Maize growth,organ development,and yield formation are highly controlled by the manner in which the plant captures,partition,and remobilizes biomass and phosphorus(P).Better understanding of biomass and P accumulation,partition,and remobilization processes will improve modeling of crop resource ***,there is still a lack of detailed data to parameterize the modeling of these processes,particula rly for modern maize cultivars.A two-year(2016 and 2017)field experiment with three P fertilization treatments(0(P0),75(P75),and 300(P300)kg P_(2)O_(5)ha^(-1))was conducted on a Fluvo-aquic soil(Quzhou,Hebei province,China)to collect data and quantify key processes for a representative modern maize cultivar(Zhengdan 958)widely grown in *** proportions of biomass and P partitioned into various maize organs were unaffected by P application *** 958 showed a much lower leaf-senescence rate than older cultivars,resulting in post-silking leaf photosynthesis being sufficient to meet grain biomass *** contrast,50%-85%of leaf P and 15%-50%of stem P accumulated pre-silking were remobilized into grain,in spite of the large proportion of post-silking P *** results are consistent with the theory that plants use resources according to the priority order of re-allocation from senescence followed by assimilation and uptake,with the re-translocation of reserves *** results also enabled us to estimate the threshold P concentrations of Zhengdan 958 for modeling crop P *** critical leaf P concentration for individual leaves was 0.25%-0.30%,with a corresponding specific leaf P(SLP)of 75-100 mg P m^(-2).The structural P concentration for leaf was 0.01%,corresponding to an SLP of 3.8 mg P m^(-2).The maximum P concentrations of leaves and stems were 0.33%and 0.29%.The residual P concentration for stems was 0.006%.

A review of solar type Ⅲ radio bursts

引用

Research in Astronomy and Astrophysics 2014年第7期14卷 773-804页

作者： hamish Andrew Sinclair Reid Heather Ratcliffe SUPA School of Physics & Astronomy University of GlasgowG12 8QQUnited Kingdom Centre for Space Fusion and AstrophysicsDepartment of PhysicsUniversity of WarwickCV47ALUnited Kingdom

Solar type III radio bursts are an important diagnostic tool in the understanding of solar accelerated electron beams. They are a signature of propagating beams of nonthermal electrons in the solar atmosphere and the solar system. Consequently, they provide information on electron acceleration and transport, and the conditions of the background ambient plasma they travel through. We review the observational properties of type III bursts with an emphasis on recent results and how each property can help identify attributes of electron beams and the ambient background plasma. We also review some of the theoretical aspects of type III radio bursts and cover a number of numerical efforts that simulate electron beam transport through the solar corona and the heliosphere.

Food,fibre,bile acids and the pelvic floor: An integrated low risk low cost approach to managing irritable bowel syndrome

World Journal of Gastroenterology 2015年第40期21卷 11379-11386页

作者： hamish Philpott Sanjay Nandurkar John Lubel Peter R Gibson Monash University Eastern HealthThe Alfred Hospital

Patients presenting with abdominal pain and diarrhea are often labelled as suffering from irritable bowel syndrome,and medications may be used often without success. Advances in the understanding of the causes of the symptoms(including pelvic floor weakness and incontinence,bile salt malabsorption and food intolerance) mean that effective,safe and well tolerated treatments are now available.

Dysphagia: Thinking outside the box

引用

World Journal of Gastroenterology 2017年第38期23卷 6942-6951页

Dysphagia is a common symptom that is important to recognise and appropriately manage, given that causes include life threatening oesophageal neoplasia, oropharyngeal dysfunction, the risk of aspiration, as well as chronic disabling gastroesophageal reflux(GORD). The predominant causes of dysphagia varies between cohorts depending on the interplay between genetic predisposition and environmental risk factors, and is changing with time. Currently in white Caucasian societies adopting a western lifestyle, obesity is common and thus associated gastroesophageal reflux disease is increasingly diagnosed. Similarly, food allergies are increasing in the west, and eosinophilic oesophagitis is increasingly found as a cause. Other regions where cigarette smoking is still prevalent, or where access to medical care and antisecretory agents such as proton pump inhibitors are less available, benign oesophageal peptic strictures, Barrett's oesophagus, adeno-as well as squamous cell carcinoma are endemic. The evaluation should consider the severity of symptoms, as well as the pretest probability of a given condition. In young white Caucasian males who are atopic or describe heartburn, eosinophilic esophagitis and gastroesophageal reflux disease will predominate and a proton pump inhibitor could be commenced prior to further investigation. Upper gastrointestinal endoscopy remains a valid first line investigation for patients with suspected oesophageal dysphagia. Barium swallow is particularly useful for oropharyngeal dysphagia, and oesophageal manometry mandatory to diagnose motility disorders.
