BACKGROUND This study aimes to evaluate the failure to thrive (FTT) recurrent event over time. METHODS This longitudinal study was conducted during February 2007 to July 2009. The primary outcome was growth failure. The analysis was done using 1283 children who had experienced FTT several times, based on recurrent events analysis. RESULTS Fifty-nine percent of the children had experienced t...

بایوچار، نام ترکیب آلی پایداری است که از تجزیه گرمایی هر نوع زیست توده تحت شرایط محدودیت اکسیژن که پیرولیز گفته می شود تهیه می گردد و در کشاورزی به منظور اصلاح شرایط فیزیکی و شیمیایی خاک استفاده می شود. هدف اصلی در این پژوهش، بررسی اثرات بایوچار برگ خرما بر خصوصیات فیزیکی و رفتار رطوبتی خاکی با بافت لوم شنی بود. پنج نوع بایوچار تحت شرایط دمایی متفاوت (300، 350، 400، 450 و 500 درجه سانتیگراد) و ...

In this article we give a characterization of monoids for which torsion freeness, ((principal) weak, strong) flatness, equalizer flatness or Condition (E) of finitely generated and (mono) cyclic acts and Condition (P) of finitely generated and cyclic acts implies regularity. A characterization of monoids for which all (finitely generated, (mono) cyclic acts are regular will be given too. We als...

حفظ منابع و ذخایر آب خاک با اعمال مدیریت صحیح و به کارگیری روش‌های پیشرفته از اقدامات مناسب در بهره­برداری از منابع محدود آب می‍باشد. در این پژوهش، اثر برخی ضایعات آلی و یک سوپرجاذب رطوبت بر مقدار آب قابل استفاده و تأخیر در نقطه پژمردگی دائم یک خاک، مربوط به دامنه­های شیب­دار رودبار بررسی شد. تیمارها شامل مقادیر 10، 20 و 50 درصد حجمی از ضایعات چای، کمپوست زباله­های شهری و ضایعات زیتون بودند که ...

Tracking data provenance (or lineage) has become increasingly important in many large-scale applications. Till now, a few methods have been proposed to record data provenance. However, most of them mainly focus on deterministic databases except Trio style lineage that aims at probabilistic databases. Processing provenance upon probabilistic database is even challenging because of the exponentia...

Knowledge of the spatial distribution and evolution of embedded charge in thin dielectric materials has important applications in semiconductor, high-power electronic device, high-voltage DC power cable insulation, high-energy and plasma physics apparatus, and spacecraft industries. Knowing how, where, and how much charge accumulates and how it redistributes and dissipates can predict destructi...

This study investigated the infection of Perkinsus beihaiensis (Perkinsozoa) in the oyster Crassostrea rhizophorae, both from a long-line cultivation system and from a nearby intertidal zone of mangrove, both in the state of Bahia, northeastern Brazil. The collections were performed in October and November 2012, and in January 2013. The oysters (n = 300) were measured, examined macroscopically ...

Abstract Introduction People with parkinsonism (PwP) are a highly heterogeneous group and the condition encompasses spectrum of motor nonmotor symptoms which variably emerge manifest across disease course, fluctuate over time negatively impact quality life. Whilst is not directly result ageing, it that mostly affects older people, who may also be living frailty multimorbidity. This study aims t...

Development of intrinsic electric charges at solid/liquid interfaces is still not fully understood and may generate large industrial damages by electrostatic discharges due to flow electrification. The pressure-wave-propagation (PWP) method used study in flowing conditions. Experimental results are shown with aluminum, brass, copper or pressboard contact demineralized water, salted glycerol min...
