Copper Catalyzed Autoxidation of Sulphur Dioxide and Inhibition by Methanoic Acid
Authors: Sharma Arun Kumar , Prasad Devarkonda Satay Narayan 
Published: September 2019

Background::
Today, acid rain problem is one of the serious global problems to
the environment in which pH of the rain water decreases, causing harmful effect to nature,
buildings, monuments, vegetation and human being as well. Therefore, the objective of the
paper to find out some organic inhibitors present in the atmosphere that inhibited the acid
rain.

Objective::
In this paper, we studied the chemistry of Cu (II)-methanoic acid-S(IV)-O2 in
acetate buffered medium by earlier reported methods in literature. Gravimetric analysis
was carried out to find the end product and confirmed that it was sulphate with 98 % recovery.

Methods::
Experiments were carried out at 303 ≤ T/K ≤ 313, 4.0 ≤ pH ≤ 5.35, 1.0×10−3
mol/dm3 ≤ S(IV) ≤ 10.0×10−3 mol/dm3, 5×10−6 mol/dm3 ≤ [Cu(II)] ≤ 2.5×10−5 mol/dm3,
6×10−6 mol/dm3≤[methanoic acid]≤7×10-4 mol/dm3. The value of apparent activation energy
and inhibition parameter B was calculated in the presence of methanoic acid found as
29.07 kJ mol-1and 3.18 x 103 mol dm-3, respectively. The thermodynamic parameters were
found as frequency factor (1.59 x 10-6s-1), entropy (-358.92 J K-1 mol-1), enthalpy (20.97 k J
mol-1), and Gibbs free energy (172.83k J mol-1), respectively.

Results::
We observed that methanoic acid acts as an inhibitor in copper catalyzed autoxidation
of SO2 in acidic medium. Therefore, on the basis of the observed results a free radical
mechanism has been identified. The results are useful for modeling rain water acidity
and therefore a great use of meteorology and atmospheric chemistry. This study is important
in understanding the mechanism of the oxidation of S(IV) by O2.

Conclusion::
This study suggests that since organic inhibitors are found in the atmosphere,
their concentrations and their influence on the oxidation of aqueous SO2 should be taken
into account. The intervention of methanoic acid in the autoxidation of aqueous SO2 plays
a role in deciding the fate of both methanoic acid and SO2. The influence of inhibitors may
be used to calculate the lifetime of SO2, Methanoic acid has high values of kinh and, therefore,
it would be degraded by sulfate radical anions in atmospheric waters.
Relating Instructional Design Components to the Effectiveness of Internet-Based Mindfulness Interventions: A Critical Interpretive Synthesis
Authors: Lippmann Marie , Laudel Helena , Heinzle Marlene , Narciss Susanne 
Published: September 2019

Background
Internet-based mindfulness interventions are a promising approach to address challenges in the dissemination and implementation of mindfulness interventions, but it is unclear how the instructional design components of such interventions are associated with intervention effectiveness.

Objective
The objective of this study was to identify the instructional design components of the internet-based mindfulness interventions and provide a framework for the classification of those components relative to the intervention effectiveness.

Methods
The critical interpretive synthesis method was applied. In phase 1, a strategic literature review was conducted to generate hypotheses for the relationship between the effectiveness of internet-based mindfulness interventions and the instructional design components of those interventions. In phase 2, the literature review was extended to systematically explore and revise the hypotheses from phase 1.

Results
A total of 18 studies were identified in phase 1; 14 additional studies were identified in phase 2. Of the 32 internet-based mindfulness interventions, 18 were classified as more effective, 11 as less effective, and only 3 as ineffective. The effectiveness of the interventions increased with the level of support provided by the instructional design components. The main difference between effective and ineffective interventions was the presence of just-in-time information in the form of reminders. More effective interventions included more supportive information (scores: 1.91 in phases 1 and 2) than less effective interventions (scores: 1.00 in phase 1 and 1.80 in phase 2), more part-task practice (scores: 1.18 in phase 1 and 1.60 in phase 2) than less effective interventions (scores: 0.33 in phase 1 and 1.40 in phase 2), and provided more just-in-time information (scores: 1.35 in phase 1 and 1.67 in phase 2) than less effective interventions (scores: 0.83 in phase 1 and 1.60 in phase 2). The average duration of more effective, less effective, and ineffective interventions differed for the studies of phase 1, with more effective interventions taking up more time (7.45 weeks) than less effective (4.58 weeks) or ineffective interventions (3 weeks). However, this difference did not extend to the studies of phase 2, with comparable average durations of effective (5.86 weeks), less effective (5.6 weeks), and ineffective (7 weeks) interventions.

Conclusions
Our results suggest that to be effective, internet-based mindfulness interventions must contain 4 instructional design components: formal learning tasks, supportive information, part-task practice, and just-in-time information. The effectiveness of the interventions increases with the level of support provided by each of these instructional design components.

Background
The quality of life (QoL) of patients with osteosarcoma (OS) may be adversely affected by the disease or its treatment. Therefore, it is important to understand the QoL of patients undergoing treatment for OS to improve the QoL. We report on the first prospective international QoL study that was embedded within a large randomized clinical trial from 4 national study groups.

Objective
This paper aimed to describe the QoL study development, methodology, accrual details, and characteristics of the QoL cohort.

Methods
A total of 2260 patients registered in the EURopean AMerican Osteosarcoma Study-1 (EURAMOS-1), of whom 97.92% (2213/2260) were eligible for the optional QoL assessment and could participate in terms of questionnaire availability. Overall, 61.86% (1369/2213) of patients and/or proxies completed the QoL evaluation at the first assessment time point (E1) after the start of preoperative treatment. The QoL measures used (self- and/or proxy reports) depending on the patient’s age and national study group. Participants and nonparticipants in the ancillary QoL study were compared regarding relevant demographic and disease-related characteristics at registration in the trial.

Results
The participation rate at time point E1 did not differ with regard to age, gender, the occurrence of pathological fracture, or the presence of any metastases at diagnosis. No differences were found regarding the primary tumor site. Only the national study group affiliation had an influence on participation. Participation decreased linearly with trial progress up to 20% at the final time point of QoL assessment.

Conclusions
This study demonstrates the feasibility of international cooperation for the purpose of assessing and understanding the QoL of pediatric and adolescent/young adult patients with cancer. Future outcomes of this QoL substudy will help to adapt interventions to improve QoL.

The objectives of this research were to study the percentage of carcass of broiler and native chicken given arenga waste fermentation by Saccaromyces cerevisiae and to study arenga waste unfermentation in the ration. Sixty of broiler chickens Arbor Acres strain and sixty native chickens were divided into four dietary treatments and three replications (10 birds/replicate). The design of this experiment was completely randomized design factorial 2x2, with factor A was feeding (A1 : arenga waste unfermented, A2 : arenga waste fermented), and factor B was chicken species (B1:native chickens, B2:broilers). The variables observed were: (1) body weight, (2) carcass, (3) percentage of carcass, and (4) Mortality.The purposes of this study were to look at the effectiveness of rations and species of chicken used for the percentage of carcass and mortality. The results showed that there was no interaction (P> 0.05) between the fed arenga waste fermented or unfermented 2.5% in the ration,and the type of chicken on weight, carcass and carcass percentage, but there was an interaction on mortality (P<0.01). The fed had no significant (P>0,05) effect on weight, carcass, and carcass percentage, but percentage, but significant effect (P <0.05) on mortality. Types of chickens had a significant effect (P <0.05) on weight, carcass, percentage of carcass and mortality. The mortality rate with unfermented arenga waste was high enough, especially in broiler chickens, but it can be tolerated on native chicken and broilers with saccaromyces cerviseae fermented arenga waste.
