A novel multi-model estimation of phosphorus in coal and its ash using FTIR spectroscopy.

The level of phosphorus must be carefully monitored for proper and effective utilization of coal and coal ash. The phosphorus content needs to be assessed to optimize combustion efficiency and maintenance costs of power plants, ensure quality, and minimize the environmental impact of coal and coal ash. The detection of low levels of phosphorus in coal and coal ash is a significant challenge due to its complex chemical composition and low concentration levels.

Petrographic and Geochemical Controls on Methane Genesis, Pore Fractal Attributes, and Sorption of Lower Gondwana Coal of Jharia Basin, India.

The Barakar coal seams of Jharia Basin have been evaluated for the geochemical and petrographic control of coalbed methane (CBM) reservoir characteristics. The coal core samples are analyzed for the total gas content, gas chromatography, stable isotopes (δC), and geochemical, petrographic and vitrinite reflectance. The significant face (1.

Variation in Pore Structure and Associated Fractal Dimensions of Barakar and Barren Measures Carbon-Rich Gas Shales of Jharia Basin, India.

The carbon-rich Barakar and Barren Measures shale beds of the Jharia basin were evaluated for variation in pore size, pore structure, and fractal dimensions. The shale core samples were obtained from exploratory boreholes drilled at the Jharia basin. The shale samples were analyzed for organo-inorganic composition by FTIR, pore size, and pore structure using BET low-pressure N adsorption and pore geometry through FE-SEM photographs.

Organo-Lithotype Controls on Cleat/Fractures, Matrix-Associated Pores, and Physicomechanical Properties of Coal Seams of Raniganj Coalfield, India.

The organo-lithotype properties of Barakar and Raniganj Formation coal seams have been investigated to assess the process of cleat origin, occurrence, and their influence on strength properties. Coal cleats have wide applications in coalbed methane gas recovery, underground mine strata mechanics, beneficiation, and pulverization. However, there is very limited information available on the cleat occurrence and controlling parameters of Indian coals.

The United Kingdom Diabetic Retinopathy Electronic Medical Record Users Group: Report 3: Baseline Retinopathy and Clinical Features Predict Progression of Diabetic Retinopathy.

Purpose: To determine the time and risk factors for developing proliferative diabetic retinopathy (PDR) and vitreous hemorrhage (VH).

Design: Multicenter, national cohort study.

Methods: Anonymized data of 50 254 patient eyes with diabetes mellitus at 19 UK hospital eye services were extracted at the initial and follow-up visits between 2007 and 2014.

The UK Diabetic Retinopathy Electronic Medical Record (UK DR EMR) Users Group, Report 2: real-world data for the impact of cataract surgery on diabetic macular oedema.

Aim: To assess the rate of 'treatment-requiring diabetic macular oedema (DMO)' in eyes for the two  years before and after cataract surgery.

Methods: Multicentre national diabetic retinopathy (DR) database study with anonymised data extraction across 19 centres from an electronic medical record system.

Inclusion Criteria: eyes undergoing cataract surgery in patients with diabetes with no history of DMO prior to study start.

The United Kingdom Diabetic Retinopathy Electronic Medical Record Users Group, Report 1: baseline characteristics and visual acuity outcomes in eyes treated with intravitreal injections of ranibizumab for diabetic macular oedema.

Aims: To describe baseline characteristics and visual outcome for eyes treated with ranibizumab for diabetic macular oedema (DMO) from a multicentre database.

Methods: Structured clinical data were anonymised and extracted from an electronic medical record from 19 participating UK centres: age at first injection, ETDRS visual acuity (VA), number of injections, ETDRS diabetic retinopathy (DR) and maculopathy grade at baseline and visits. The main outcomes were change in mean VA from baseline, number of injections and clinic visits and characteristics affecting VA change and DR grade.

UK AMD EMR USERS GROUP REPORT V: benefits of initiating ranibizumab therapy for neovascular AMD in eyes with vision better than 6/12.

Background/aims: To study the effectiveness and clinical relevance of eyes treated with good (better than 6/12 or >70 Early Treatment Diabetic Retinopathy Study letters) visual acuity (VA) when initiating treatment with ranibizumab for neovascular age-related macular degeneration (nAMD) in the UK National Health Service. Currently eyes with VA better than (>) 6/12 are not routinely funded for therapy.

Methods: Multicentre national nAMD database study on patients treated 3-5 years prior to the analysis.

The neovascular age-related macular degeneration database: report 2: incidence, management, and visual outcomes of second treated eyes.

Purpose: To study the characteristics of second treated eyes in patients with neovascular age-related macular degeneration (nAMD) treated with ranibizumab in the United Kingdom National Health Service.

Design: Multicenter national nAMD database study.

Participants: Twelve thousand nine hundred fifty-one treatment-naïve eyes of 11,135 patients receiving 92,976 ranibizumab injections.

Irreversible blindness due to multiple tuberculomas in the suprasellar cistern.

A 14-year-old girl developed fever, severe headache, vomiting, and no light perception in both eyes over a 3-day period without a previous complaint of visual or other neurologic difficulties. Neuro-ophthalmologic examination was normal apart from meningismus and blindness. Brain imaging showed ventriculomegaly and multiple enhancing nodules around the optic chiasm.

Isolated abscess of extraocular muscle in two young boys: clinical and imaging features.

Purpose: To report two cases of a cystic isolated extraocular muscle abscess in a young boy.

Method: Case report.

Results: Two cases of young boys with a cystic isolated extraocular muscle abscess are described.

Use of the direct puncture technique in management of capillaro-venous malformations: case report.

BACKGROUND: Preoperative devascularization of the capillaro-venous malformations located in the aero-digestive tract is important for surgeons, to minimize blood loss during surgical excision of malformations. CASE PRESENTATION: Here we present two cases of capillaro-venous malformation in which we could successfully achieve preoperative devascularization, by directly injecting n-butyl cyano acrylate into the capillaro-venous bed. This technique is relatively easy, safe and cheap, and can be carried out immediately before surgery.
