Punjab Chief Minister Captain Amarinder Singh on Tuesday said a decision on any electoral alliance in Punjab for the 2019 Lok Sabha elections would be taken by the Congress high command at the appropriate time.He was replying to a media query about the possibility of a poll alliance on the lines of the one forged by Samajwadi Party with Bahujan Samaj Party and Congress in Uttar Pradesh.Talking to journalists on the sidelines of the Entrepreneurship and Innovation convention in Patiala, Capt. Amarinder Singh said any decision in this regard would be taken by the party’s central leadership.In response to another question, he hinted at a new Sports Minister being appointed in the State’s Cabinet expansion, which is expected to take place soon. “The new Sports Policy would be finalised thereafter,” he said.On the issue of alleged illegal mining in Patiala, he promised a thorough probe and action. “I won’t allow illegal mining to continue,” he said, pointing out that he had already issued stringent directives to the police and the concerned administrative departments to crack down against such activities taking place in any part of the State.On the report submitted by the Special Task Force (STF) in the drugs case, Capt. Singh said the matter was sub judice and he could, therefore, not comment on the same.
The Bangladesh Nationalist Party (BNP) chairperson Khaleda Zia. Prothom Alo File PhotoThe High Court on Thursday extended the bail of Bangladesh Nationalist Party (BNP) chairperson Khaleda Zia until 19 July in Zia Orphanage Trust graft case.The HC bench of justice M Enayetur Rahim and justice Md Mostafizur Rahman passed the order following a petition filed by Khaleda’s lawyer, reports UNB.The court also adjourned the hearing on the review petition filed by the BNP chief against a lower court verdict sentencing her to five years’ imprisonment in the graft case.Earlier, in the day, the HC started hearing on the review petition around 11:00am following the order of the Supreme Court.Khaleda’s lawyer Abdur Rezak Khan read out the FIR from the paper book while AJ Mohammad Ali read out the charge sheet before the court.Senior BNP leader Moudud Ahmed said the bail of Khaleda Zia in the case expired today and the lawyers filed a petition before the court seeking extension of the bail.On 5 July, a petition was filed with the High Court seeking extension of its earlier order granting four-month interim bail to Khaleda Zia in the Zia Orphanage Trust graft case.On 12 March, the HC granted four-month bail to Khaleda in the case which was to expire today (12 July).On 8 February, the Dhaka Special Court-5 convicted the former prime minister and BNP chairperson Khaleda Zia and sentenced her to five years’ imprisonment in the Zia Orphanage Trust graft case.She was then sent to the abandoned central jail on Nazimuddin Road in the capital.
E-Liquids are usually comprised of glycerin and propylene glycol along with a flavor additive. Glycerin, when heated, predominantly forms acrolein and formaldehyde, while propylene glycol predominantly forms acetone and acetaldehyde. Certain flavor additives have shown enhanced aldehyde formation, as well.

This method employs a 4-(2-aminooxyethyl)-morpholin-4-ium chloride (AMAH) coating on a silicon base. Aldehydes selectively react with AMAH to form an oxime, which is more stable and easier to study than an aldehyde.Aerosols were generated using a cigarette-smoking robot and were collected in Tedlar bags. The robot allowed for control over puff duration, puff volume, and puff frequency. The aerosols flowed through the microreactors from the bags using an evacuation process and then reacted with AMAH. The AMAH oxime compound was neutralized to form an AMA adduct that was then studied using gas chromatography.Both the first generation and next generation e-cigarettes produced some amount of acetaldehyde, acrolein, and formaldehyde, but acealdehyde and formaldehyde were in higher concentrations than acrolein. All of the aldehydes were present in lower concentrations than what is found in cigarette smoke using Health Canada Intense Puffing Regime. Notably, the next-generation e-cigarettes, which have a tank-type atomizer, produced higher levels of aldehydes and acetone. The authors attribute this to the higher battery output.To understand the puffing topology, Ogunwale et al., used 60-mL syringes to manually vary puff duration and volume to more accurately replicate real-life usage. Puffing duration and the particular flavor contributed to the formation of reactive aldehydes, although these factors played a smaller role than battery output in the amount of aldehydes present. If puffing duration was around 4.0 seconds/puff, more aldehydes were present compared to shorter or longer puffing. The average user puffs for 3.5 to 4.3 seconds.Finally, Ogunwale et al. used 1H NMR to detect and quantify the presence of hemiacetals formed from aldehydes. They found that hemiacetals did not form in any of the first-generation e-cigarettes flavors, and they did not form in three of the next-generation flavors tested. Only one flavor that was tested formed hemiacetals within a battery output that was within the range of normal use. This study provides valuable information on the safety of e-cigarettes. In general, the higher the battery output, the higher the aldehyde levels in the vapor. Certain aldehydes, such as acrolein, acetaldehyde, and formaldehyde, have been shown to contribute to CVD even in low levels. All of the e-cigarettes tested in this study had some amount of these aldehydes present. Hazardous chemicals discovered in flavored e-cigarette vapor More information: Mumiye A. Ogunwale et al. Aldehyde Detection in Electronic Cigarette Aerosols, ACS Omega (2017). DOI: 10.1021/acsomega.6b00489AbstractAcetaldehyde, acrolein, and formaldehyde are the principal toxic aldehydes present in cigarette smoke and contribute to the risk of cardiovascular disease and noncancerous pulmonary disease. The rapid growth of the use of electronic cigarettes (e-cigarettes) has raised concerns over emissions of these harmful aldehydes. This work determines emissions of these aldehydes in both free and bound (aldehyde–hemiacetal) forms and other carbonyls from the use of e-cigarettes. A novel silicon microreactor with a coating phase of 4-(2-aminooxyethyl)-morpholin-4-ium chloride (AMAH) was used to trap carbonyl compounds in the aerosols of e-cigarettes via oximation reactions. AMAH–aldehyde adducts were measured using gas chromatography–mass spectrometry. 1H nuclear magnetic resonance spectroscopy was used to analyze hemiacetals in the aerosols. These aldehydes were detected in the aerosols of all e-cigarettes. Newer-generation e-cigarette devices generated more aldehydes than the first-generation e-cigarettes because of higher battery power output. Formaldehyde–hemiacetal was detected in the aerosols generated from some e-liquids using the newer e-cigarette devices at a battery power output of 11.7 W and above. The emission of these aldehydes from all e-cigarettes, especially higher levels of aldehydes from the newer-generation e-cigarette devices, indicates the risk of using e-cigarettes.

Many people believe that they are healthier than cigarettes, but others say that the effects of e-cigarette vapors are largely unknown. Medical organizations have generally taken a cautious approach and do not specifically recommend e-cigarettes for stopping smoking or as a healthier alternative to smoking. © 2017 Phys.org One area of concern is the amount of aldehydes present in e-cigarette smoke. These aldehydes are present in tobacco cigarettes in larger quantities than in e-cigarettes, but the levels in e-cigarettes are still not known. Additionally, the amount that is considered dangerous for cardio vascular disease (CVD) is a topic of debate. Some studies have shown that even small amounts of certain aldehydes can lead to progression of CVD.Researchers from the University of Louisville’s Tobacco Regulation and Addiction Center conducted quantitative analyses of both older (first generation) and newer-model e-cigarette cartridges using a variety of flavors. They used a new method for trapping reactive carbonyls that are then subsequently stabilized using an oximation reaction. They found that newer devices produced more harmful aldehydes than first generation e-cigarettes. Their work appears in ACS Omega.E-cigarettes cartridges contain battery-powered coils that serve to heat and vaporize e-Liquid. Based on this study, the amount of reactive aldehydes in e-cigarette vapor are largely due to the cartridge’s battery power. The higher the battery power, the higher the aldehyde levels. While e-cigarette aerosols contain aldehydes that are known to contribute to CVD, the exact levels have not been definitively determined largely because of the difficulties associated with trapping and studying reactive aldehydes. New models, or “next-generation,” e-cigarettes have a higher battery power than older ones. Furthermore, older models have a fixed battery output (4.6 W) while the next-generation ones have variable output (9.1 W, 11.7 W, 14.7 W, 16.6 W). The authors wanted to look at this next-generation of e-cigarettes to quantitatively determine aldehyde levels as well as determine if e-Liquid flavor makes a difference in aldehyde formation. In order to do this, they took into account the formation of hemiacetals from aldehydes, something that prior studies did not address.The aldehydes that are of greatest concern are acetaldehyde, acrolein, and formaldehyde. Acrolein, in particular, has been shown to advance CVD, even when a person is exposed to low levels. Formaldehyde has also been associated with CVD in low concentrations. Explore further
