Removal of copper and zinc from wastewater using chitosan

Heavy metals are one of the most toxic materials to the environment. Adsorption is the process which is used for the removal of heavy metals from wastewater. Many researches have been conducted to remove heavy metals using different materials. Various adsorbents have been used to remove different type of heavy metal ions from wastewater especially those that are harmful to mankind. Activated carbons, plant or lignocellulosic wastes, clays and biopolymers are the most common adsorbents used. For this research, chitosan was used as a adsorbent to remove copper and zinc from wastewater. Chitosan, a type of biopolymer, is a good adsorbent to remove the heavy metal ions from wastewater. The synthetic wastewater was prepared in the laboratory to conduct the experiments. Batch experiments were conducted to obtain the optimum conditions for copper and zinc. Effect of parameter like pH, adsorbent dose, contact time, temperature and initial metal ion concentration were also determined. The optimum conditions obtained were 360 min contact time, 200 mg adsorbent dose and pH 5 for copper and 180 min contact time, 200 mg adsorbent dose and pH 7 for zinc. Adsorption behavior could be described using the Langmuir, Freundlich and Temkin isotherm model. Adsorption data was well fitted in Langmuir isotherm model for both metals. The maximum adsorption capacity was found to be 89% for copper and 96.97% for zinc. The kinetics of adsorption could describe using pseudo first order and pseudo second order kinetic model. In all cases the kinetics follows the pseudo second order rate equation. The negative values of ∆G0 and ∆H0 indicate that the process was thermodynamically spontaneous and exothermic in nature

Scrub typhus in third trimester of pregnancy: dilemmas in diagnosis and management

Scrub typhus is an acute febrile illness rarely diagnosed in pregnancy. Here we report a case of scrub typhus in the third trimester of pregnancy, its associated complications and its management to ensure a favourable fetomaternal outcome. Mrs X, a 22- year old primigravida, was diagnosed with scrub typhus at 38 weeks of pregnancy after developing high- grade fever for 12 days. An atypical eschar was seen on one foot. Her ultrasonography revealed foetal tachycardia and severe oligohydramnios. She was started on tab azithromycin 500 mg OD but remained febrile even after two days. Fever subsided at dose of 1gm/day. When she was afebrile for 48 hours and adequately hydrated, labour was induced and she delivered vaginally a full-term alive baby of 2.2 kg. Vertical transmission was not observed in the baby. Scrub typhus is an easy-to-treat cause of acute undifferentiated febrile illness in the Indian subcontinent, and should always be a differential diagnosis even in the absence of a pathognomic eschar. Timely treatment ensures a favourable fetomaternal outcome.

Rethinking post-disaster relocation in urban India

"After natural disasters, governments often relocate vulnerable urban communities in the name of humanitarian relief. But urban communities rarely welcome such relocation, since it frequently exacerbates their daily challenges or creates new risks. Indeed, resettlement after a disaster is often another form of eviction. This briefing discusses the situation in Chennai, where state and local authorities have been building resettlement tenements on inland marsh areas using centrally sponsored schemes for affordable housing. These have been used as a ‘quick fix’ after disasters, but without addressing communities’ underlying needs and inequalities. Their siting has also increased flood risk across the urban area, creating new risks. Instead, India should develop participatory and risk-reducing plans and policies for relocation, and also help vulnerable communities address the risks where they currently live. This briefing is part of the project ‘Longterm implications of humanitarian responses: a case of Chennai’. The research was conducted in 2016 by the Indian Institute for Human Settlements (IIHS) and Madras Institute for Development Studies (MIDS).

Quantum Zeno effect: a qutrit controlled by a qubit

For a three-level system monitored by an ancilla, we show that quantum Zeno effect can be employed to control quantum jump for error correction. Further, we show that we can realize cNOT gate, and effect dense coding and teleportation. We believe that this work paves the way to generalize the control of a qudit

Double-toric code

We construct a double-toric surface code by exploiting the planar tessellation using a rhombus-shaped tile. With n data qubits, we are able to encode at least n/3 logical qubits or quantum memories. By a suitable arrangement of the tiles, the code achieves larger distances, leading to significant error-correcting capability. We demonstrate the robustness of the logical qubits thus obtained in the presence of external noise. We believe that the optimality of the code presented here will pave the way for design of efficient scalable architectures

Quantum error correction beyond the toric code: dynamical systems meet encoding

We construct surface codes corresponding to genus greater than one in the context of quantum error correction. The architecture is inspired by the topology of invariant integral surfaces of certain non-integrable classical billiards. Corresponding to the fundamental domains of rhombus and square torus billiard, surface codes of genus two and five are presented here. There is significant improvement in encoding rates and code distance, in addition to immunity against noise

Indian Capital Market - Great Investment Story, A Fundamental Approach

The dissertation aims to evaluate the growth prospects in the Indian stock market. The study is conducted by analyzing the three growth sectors of the Indian economy namely Information Technology, Textile industry and Capital Goods and Equipment industry. The backbone of the research is four companies in each sector whose financial statements of last three years have been closely studied and with a fundamental approach the coming years profits have been forecast. Further, P/E multiple has also been forecast adjusted for any re-rating wherever found necessary. The study clearly establishes a good growth in the share prices of these companies if invested now

Long-term implications of humanitarian responses: the case of Chennai

"Following the Indian Ocean tsunami in 2004, Tamil Nadu lost about 8,000 people and the lives and livelihoods of over 897,000 families were affected. In 2015, Chennai, the capital city of Tamil Nadu, was brought to a standstill by floods which killed 289 people, left 1,000 injured, and damaged property and livelihoods worth US$2.2 billion. These extreme events and others, such as the 2003–04 drought and the 2016 cyclones, mobilised humanitarian action from a range of actors in Chennai. This study examines how humanitarian responses and post-disaster relocations fit into the wider development vision of large and fast-growing metropolises such as Chennai.
