Low temperature synthesis, magnetic and magnetotransport properties of (La1-xLux)0.67Ca0.33MnO3 (0 < x < 0.12) system

We have been able to synthesize Lu+3 substituted La0.67Ca0.33MnO3 (LCMO) by an auto-combustion method. Synthesis of this compound is not successful by conventional ceramic or other chemical methods. Magnetic and electrical transport properties of the Lu substituted LCMO [(La1-xLux)0.67Ca0.33MnO3 (0 < x < 0.12)] system have been investigated and compared with those of the Y+3, Pr+3, Dy+3 and Tb+3 substituted LCMO systems. All the compounds show a ferromagnetic metal to paramagnetic insulator transition at TC. The tolerance factor reduces from 0.917 for x = 0 to 0.909 for x = 0.12 and for this range all are ferromagnetic metals indicating the dominance of the coupling between spins due to double exchange over the antiferromagnetic superexchange interaction. The transition temperatures and magnetization decrease as the Lu concentration increases. This is satisfactorily accounted for on the basis of transition from ferromagnetic at x = 0 to canted spin order for x > 0. All the samples show higher magnitude of MR compared to that in pure LCMO at 80 kOe field in the temperature range of 5 to 320K. A fairly high value of low field magnetoresistance (LFMR) of about 30% is obtained in all the samples at a field less than 5 kOe.Comment: Total 35 pages of text and figure

Assessment of Battery Energy Storage Systems Using the Intuitionistic Fuzzy Removal Effects of Criteria and the Measurement of Alternatives and Ranking Based on Compromise Solution Method

The energy storage is an important character for sustainable energy structures and the prospective future economy. This paper aims to propose a multi-attribute decision analysis (MADA) approach to prioritize and choose the energy storage system (ESS) alternatives in terms of the different technical, economic, environmental and social aspects of them. In this line, an integrated approach is developed with the combination of intuitionistic fuzzy sets (IFSs), a method using the removal effects of criteria (MEREC), rank sum (RS) and the measurement of the alternatives and ranking based on compromise solution (MARCOS) methods for prioritizing the ESSs. The IF-MEREC-RS was used to find the integrated weight by combining the objective and subjective weights of the different indicators for prioritizing the ESSs. The MARCOS method was implemented to rank the various ESSs over several crucial indicators of sustainability. The practical outcome illustrates that the Li-ion battery (LIB) is the best ESS among all of the options, and this is followed by NaSB and NiMHB. A sensitivity investigation with the diverse weights of the indicators shows the impact of the risk preferences on an alternative prioritization. A comparison is discussed with the outcomes of the different presented, extant approaches to certify the superiority of the presented approach

An exploratory study of dose escalation versus standard focal High Intensity Focused Ultrasound for treating non-metastatic prostate cancer.

Objective To compare cancer control rates of standard compared to dose escalation focal high-intensity focused ultrasound (HIFU) of prostate cancer. Materials and methods A prospectively maintained HIFU (Sonablate® 500) database identified 598 patients were identified who underwent focal HIFU (Sonablate® 500) (March/2007-November/2016). Follow-up occurred with 3-monthly clinic visits and PSA testing in the first year. Thereafter, PSA was measured 6-monthly. mpMRI with biopsy was used for MRI-suspicion of recurrence. Treatments were delivered in a quadrant or hemiablation fashion depending on the gland volume as well as tumour volume and location. Prior to mid-2015, standard focal-HIFU was used (two HIFU blocks); after this date some urologists conducted dose escalation focal-HIFU (3 overlapping HIFU blocks). Propensity matching was used to ensure two matched groups leading to 162 cases for this analysis. Treatment failure was defined by any secondary treatment (systemic therapy, cryotherapy, radiotherapy, prostatectomy, or further HIFU), metastasis from prostate cancer without further treatment, tumour recurrence with Gleason score >/=7 (>/=3+4) on prostate biopsy without further treatment, or prostate cancer-related mortality. Complications and side-effects were also compared. Results Median age was 64.5 years (IQR 60-73.5) in the standard focal-HIFU group and 64.5 years (IQR 60-69) in the dose-escalation group. Median prostate volume was 37ml (IQR 17-103) in standard group and 47.5ml (IQR 19-121) in the dose-escalation group. As tumour volume on mpMRI and Gleason score were major matching criteria these were identical with 0.43ml (IQR 0.05-2.5) and Gleason 3+3=6 in 1/32 (3%), 3+4=7 in 27/32 (84%), and 4+3=7 in 4/32 (13%). Recurrence in treated areas were found in 10/32 (31%) when standard treatment zones were applied, and in 6/32 (19%) of dose-escalation focal-HIFU (p=0.007). Conclusion This exploratory study shows that dose escalation focal-HIFU may achieve higher rates of disease control compared to standard focal-HIFU. Further prospective comparative studies are needed

Synthesis and Kinetic Evaluation of Cyclophostin and Cyclipostins Phosphonate Analogs As Selective and Potent Inhibitors of Microbial Lipases

A new series of customizable diastereomeric <i>cis-</i> and <i>trans</i>-monocyclic enol-phosphonate analogs to Cyclophostin and Cyclipostins were synthesized. Their potencies and mechanisms of inhibition toward six representative lipolytic enzymes belonging to distinct lipase families were examined. With mammalian gastric and pancreatic lipases no inhibition occurred with any of the compounds tested. Conversely, <i>Fusarium solani</i> Cutinase and lipases from <i>Mycobacterium tuberculosis</i> (Rv0183 and LipY) were all fully inactivated. The best inhibitors displayed a <i>cis</i> conformation (H and OMe) and exhibited higher inhibitory activities than the lipase inhibitor Orlistat toward the same enzymes. Our results have revealed that chemical group at the γ-carbon of the phosphonate ring strongly impacts the inhibitory efficiency, leading to a significant improvement in selectivity toward a target lipase over another. The powerful and selective inhibition of microbial (fungal and mycobacterial) lipases suggests that these seven-membered monocyclic enol-phosphonates should provide useful leads for the development of novel and highly selective antimicrobial agents
