Assessment of monthly variation in heavy metal characteristics of Electroplating industrial untreated wastewater at selected sites of Chandigarh

With the contest of urbanization and industrial development, electroplating industries have grown rapidly. The different chemicals, metal salts and discharge of large volume of wastewater with inefficient treatment facilities had created the pollution load on water bodies.  The present study was carried out to investigate the assessment of the monthly variation of pH and heavy metals (Cr, Ni, Zn, Fe) of electroplating untreated industrial wastewater from the selected study sites viz. SS-1: Atul Industries, SS-2: Suresh Fasteners, SS-3: Bajrang Industrial Company, SS-4: Stylex Industries, SS-5: Karan Industries, SS-6: Avon Industries, SS-7: Geetika Enterprises, SS-8: Atop Fasteners, SS-9: Accufit Fasteners and SS-10: Ashoka Furniture Udyog at industrial area phase I and phase II of Chandigarh. The untreated electroplating wastewater samples were collected from ten study sites (SS-1 to SS-10) and were analyzed following the standard methods for the examination of water and wastewater. The results of the present study revealed that the maximum concentration of heavy metals such as Zn (122.20 mg/l)during the month of August 2019 at the SS-8, Ni (156.37 mg/l) during the month of August 2019 at the SS-4, Cr (467.01 mg/l) during the month of October 2019 at the SS-5 and Fe (13.22 mg/l)during the month of December 2019 at the SS-2. The load of metallic ions discharge from the electroplating industries before any treatment from the selected study sites (SS-1 to SS-10) was found in the following order as Cr>Ni>Zn>Fe. Thus the present study would provide baseline data for the development of treatment strategies for wastewater discharge from electroplating industries and also in minimizing the effects of heavy metal contamination of receiving water bodies

Developing Framework for the Implementation of Advanced Manufacturing Technologies in Small and Medium-Sized Enterprises

Intense competition, demanding customers, and shortening product life cycles are prompting small- and medium-sized enterprises to invest in advanced manufacturing technologies (AMTs). Small manufacturers often depend on large manufacturers for orders and so require design as well as manufacturing flexibility on their part. One way of achieving the flexibility is through adoption of AMTs. The decision to invest in AMT is a major decision and thus requires proper consideration to all the aspects of the implementation process before a final commitment is made. Although the technical capabilities of AMTs are well proven, neither practitioner nor academics agree upon a framework for its successful implementation. Using Churchill’s model (Steps 1 and 2) and drawing a link from the available literature, a theoretical framework is developed for the successful implementation of AMTs in small- and medium-sized enterprises. Three implementation phases—namely, planning, preimplementation, and postimplementation—with 14 major issues have been developed; 52 constituent factors have been identified from these issues through literature review and interviews with industry professionals

Synthesis and cytotoxic studies of a new series quinolinoxymethylcoumarins

4-Bromomethylcoumarins (1a-k) were reacted with 8-hydroxyquinolines (2a-b) to yield quinolinoxymethylcoumarins (3a-o). The structure of all the synthesized compounds were confirmed by spectral studies and screened for their anticancer activities against Dalton's Ascitic Lymphoma (DAL) and Ehrlich Ascites Carcinoma (EAC) cell lines. Out of these, the compound (3d) (R = 6-Benzyl, R1=H) was found to be the most potent cytotoxic compound against DAL cell line with IC50 value of 45.86 μg/mL and the compound (3i) (R = 6-i-Pr, R1= CH3) against EAC cell line with IC50 value of 39.26 μg/mL

Prosthetic management of severely resorbed mandibular ridge using neutral zone technique in complete dentures: a case report

Any prosthodontic procedure aims to restore a patient\u27s function, contours, aesthetics, speech, and health to normal. In traditional complete dentures, achieving optimal denture stability is always found to be a challenge. This is often exacerbated in resorbed mandibular ridges. Therefore, this article describes a strategy for enhancing the retention of mandibular complete dentures for individuals with an extremely resorbed ridge. A patient reported to the department of prosthodontics with a chief complaint of loose dentures and wanted to get them replaced. A complete clinical examination was carried out which revealed severely resorbed mandibular ridge. After a complete evaluation, prosthetic rehabilitation with a complete denture using the neutral zone technique was panned. The complete denture was made and delivered to the patient was superior in terms of stability, function and aesthetics. The clinician should understand the advantages of the neutral zone technique and implement it in clinical practice so that a prosthesis that is functionally, physiologically and psychologically acceptable to the patient can be delivered
