This study explores the fabrication of Fe-based amorphous/crystalline coating by air plasma spraying and its dependency on the coating parameters(plasma power,primary gas flow rate,powder feed rate,and stand-off distance).X-ray diffraction of the coatings deposited at optimized spray parameters showed the presence of amorphous/crystalline *** deposited at a lower plasma power and highest gas flow rate exhibited better density,hardness,and wear *** coatings demonstrated equally good resistance against the corrosive environment(3.5wt%NaCl solution).Mechanical,wear,and tribological studies indicated that a single process parameter optimization cannot provide good coating performance;instead,all process parameters have a unique role in defining better properties for the coating by con-trolling the in-flight particle temperature and velocity profile,followed by the cooling pattern of molten droplet before impingement on the substrate.

Condition based maintenance(CBM) is one of the solutions to machinery maintenance requirements. Latest approaches to CBM aim at reducing human engagement in the real-time fault detection and decision making. Machine learning techniques like fuzzy-logic-based systems, neural networks, and support vector machines help to reduce human involvement. Most of these techniques provide fault information with 100% confidence. It is undeniably apparent that this area has a vast application scope. To facilitate future exploration, this review is presented describing the centrifugal pump faults, the signals they generate, their CBM based diagnostic schemes, and case studies for blockage and cavitation fault detection in centrifugal pump(CP) by performing the experiment on test rig. The classification accuracy is above 98% for fault detection. This review gives a head-start to new researchers in this field and identifies the un-touched areas pertaining to CP fault diagnosis.

Background: The prognosis of patients with Epidermal Growth Factor Receptor (EGFR) overexpression in inoperable Locally Advanced Squamous Cell Carcinoma of Head and Neck (LASCCHN) remains poor. Nimotuzumab is an Anti EGFR humanized monoclonal antibody approved for treatment of LASCCHN, with concurrent chemoradiation. Objective: To assess the efficacy and safety of nimotuzumab with concurrent chemoradiation in inoperable LASCCHN patients. Methodology: This is a single-centre, single arm, retrospective study evaluating 35 patients with histologically confirmed inoperable LASCCHN (stages III-IV). The patients were administered IV cisplatin 50 mg/m2 and IV nimotuzumab 200 mg for 6 - 7 weeks, along with radiotherapy of 6600 - 7000 cGy over 35 fractions. Patients were evaluated over response evaluation criteria in solid tumors (RECIST) criteria 12 weeks after the last cycle of chemotherapy. They were also followed up for overall survival and relapse free survival. Results: The median duration of follow-up was 20 months. The most common site of cancer was oropharynx (68.6%). One patient was lost to follow up. Objective Response Rate (ORR) was observed in 97% of the patients with 17 patients (48.6%) achieving complete response (CR) and 17 patients (48.6%) achieving partial response (PR). The median overall survival was 22.7 months (95% CI: 21.30, 34.27). The median relapse free survival was 16.7 months (95% CI: 9.80, 24.50). Nimotuzumab was safe and well tolerated with few mild, self-limiting adverse events. Conclusion: Nimotuzumab with chemoradiation is a safe and efficacious option in patients with LASCCHN. Larger studies are needed to verify the same.

1、中国无性系和群体品种的芽叶所含的纤维组织比例要高于肉质的阿萨姆类型的无性系和群体品种。 2、修剪茶树的芽叶,其纤维组织所占的比例最小。随着轻修剪程度减弱,纤维组织也成比例地增加。不进行任何修剪的茶树,其芽叶所含的纤维组织百分比最高。 3、可明显地看出,到茶季末,新梢中的纤维组织所占的百分率没有上升的趋势。然而,影响芽叶生长的气候条件,很可能影响茎纤维组织比例的增加或减少。 4、要降低制茶中废茶的百分率,应避免粗采。对于中国种或中国杂交的无性系和群体品种,采用轻修剪是不利的。
