All-Printed Roll-to-Roll Perovskite Photovoltaics Enabled by Solution-Processed Carbon Electrode.

Perovskite photovoltaics have shown great promise in device efficiency but also the promise of scalability through solution-processed manufacture. Efforts to scale perovskites have been taken through printable mesoporous scaffolds and slot die coating of flexible substrates roll-to-roll (R2R). However, to date there has been no demonstration of entirely R2R-coated devices due to the lack of a compatible solution-processable back electrode; instead, high-value evaporated metal contacts are employed as a post process.

Acetonitrile based single step slot-die compatible perovskite ink for flexible photovoltaics.

The demonstration of photovoltaic devices with high power conversion efficiencies using low cost perovskite materials hints at the possibility of dramatically lowering the cost of solar energy. Key to further exploiting the potential of these materials is developing rapid processing techniques that can be used to deliver lower cost high throughput manufacture. This work details the development of low viscosity rapid drying perovskite formulations designed to give high quality solar films when slot-die coated on flexible roll-to-roll compatible substrates.

Perovskite Photovoltaic Modules: Life Cycle Assessment of Pre-industrial Production Process.

Photovoltaic devices based on perovskite materials have a great potential to become an exceptional source of energy while preserving the environment. However, to enter the global market, they require further development to achieve the necessary performance requirements. The environmental performance of a pre-industrial process of production of a large-area carbon stack perovskite module is analyzed in this work through life cycle assessment (LCA).

Hierarchical structures of cactus spines that aid in the directional movement of dew droplets.

Three species of cactus whose spines act as dew harvesters were chosen for this study: Copiapoa cinerea var. haseltoniana, Mammillaria columbiana subsp. yucatanensis and Parodia mammulosa and compared with Ferocactus wislizenii whose spines do not perform as dew harvesters.

Reproductive outcome after laparoscopic treatment of minimal and mild endometriosis using Helica Thermal Coagulator.

Objective: To investigate the reproductive outcome following Helica Thermal Coagulator (Helica TC) in an infertile population with early-stage endometriosis.

Design: A clinical observational trial conducted in a NHS tertiary referral centre for treatment of endometriosis. Forty-four healthy infertile women (mean age 21 years, range 18-34 years) with laparoscopically confirmed diagnosis of minimal (stage I) or mild (stage II) endometriosis were included.

Topical antiseptic agent after large loop excision of the transformation zone: results of a randomised controlled trial.

One hundred patients undergoing large loop excision of the transformation zone (LLETZ) were randomised to receive postoperative local treatment with sultrin (sulphathiazole 3.42%, sulphacetamide 2.86%, sulphabenzamide 3.

The requirements and development of neutron beams for neutron capture therapy of brain cancer.

One of the two overriding conditions for successful BNCT is that there must be a sufficient number of thermal neutrons delivered to each of the boronated cells in the tumour bed (target volume). Despite the poor experience with BNCT in the USA some 40 years ago, the continued apparent success of BNCT in Japan since 1968, lead indirectly to the re-start of clinical trials on BNCT in 1994 at both Brookhaven and MIT. Similar trials will start soon at Petten in Europe.

Synthesis of an endogeneous lectin, galectin-1, by human endothelial cells is up-regulated by endothelial cell activation.

The pattern of expression of an endogenous lectin, galectin-1, was examined in human lymphoid tissue. Galectin-1 was detected in the endothelial cells lining specialized vessels, termed high endothelial venules, in activated lymphoid tissue, but not in a resting lymph node. Cultured endothelial cells (human aortic and umbilical vein endothelial cells (HAECs and HUVECs)) expressed galectin-1.

Squamous cell carcinoma antigen: pretreatment levels as an indicator of advanced or metastatic disease.

Pretreatment values of squamous cell carcinoma antigen (SCC) were obtained in 100 consecutive patients with squamous cell carcinoma of the cervix presenting to the Regional Gynaecological Oncology Centre in Gateshead, UK. Nine patients deemed to have locally advanced disease not suitable for primary surgery had elevated levels. Ninety-one patients were suitable for primary surgery.

Radical vulvectomy and groin node dissection in a patient with chronic neutropenia-maintenance of leucocyte count using granulocyte colony-stimulating factor.

A patient was referred for consideration of radical surgery in the presence of chronic neutropenia. We report the successful maintenance of an adequate neutrophil count during the perioperative period using Granulocyte colony-stimulating factor (GCSF), resulting in successful primary healing of the wounds in the absence of infective complications. The use of GCSF in gynecology is briefly reviewed.

Evaluating the complaint of fatigue in primary care: diagnoses and outcomes.

Purpose: This case series describes associated diagnoses and prognoses of persistent fatigue in a community-based, primary care population.

Patients And Methods: All patients presenting to a private practice internist with a chief complaint of fatigue of more than 1 month's duration were prospectively evaluated with clinically directed examination and diagnostic testing. Patients were excluded if they had a previously diagnosed illness associated with fatigue.

Leading health care into the 21st century.

If there is a consistency in the professional lives of those who manage in the health care field, surely it is characterized by inconsistency. Change. For more nearly two decades now, since the full impact of the Medicare/Medicaid legislation hit, the health care industry has undergone profound, continual, and lasting change.
