Lime Production

The Evadale, TX, USA, mill recently engaged in a major lime kiln and recausticizing upgrade. The centerpiece of the project was to upgrade the existing lime kiln feed system to a new LimeFlash feed system, a trademarked technology from Andritz. The feed system in Evadale is the first installation in North America of this technology, and the second installation in the world. The feed system increased the capacity of the lime mud dryer (LMD) fed kiln from 350 tons/day of lime product to 480 tons/day of kiln product, with less than 3% carbonate. The system mixes hot flue gasses with the lime mud before the gas enters the feed end housing, which allows the kiln to operate at a higher feed end temperature without plugging and lime splitting. In startup and low capacity situations, lime mud is fed directly into the kiln rotating part, which eliminates potential plugging problems. Startup and operational experience, along with selected environmental performance, is reviewed.

Gastric ulcers or the peptic ulcer is the primary disease that affects the gastrointestinal system. A large extent of the population in the world are suffering from the disease, and the age group of people those who suffer from ulcers are 20-55years. Herbs are known to the human beings that are useful in the treatment of diseases, and there are a lot of scientific investigations that prove the pharmacological activity of herbal drugs. Practitioners have been using the herbal material to treat the ulcers successfully, and the same had been reported scientifically. Numerous publications have been made that proves the antiulcer activity of the plants around the world. The tablets were investigated for the antiulcer activity in two doses 200 and 400mg/kg in albino Wistar rats in the artificial ulcer those are induced by the ethanol. The prepared tablets showed a better activity compared to the standard synthetic drug and the marketed ayurvedic formulation. The tablets showed a dose-dependent activity in ulcer prevention and treatment. Many synthetic drugs are available for the ulcer treatment, and the drugs pose the other problems in the body by showing the side effects and some other reactions. This limits the use of synthetic drugs to treat ulcers effectively. Herbs are known to the human beings that are useful in the treatment of diseases, and there are a lot of scientific investigations that prove the pharmacological activity of herbal drugs.

Tobacco use is projected to kill 1 billion people in the 21st century. Tobacco Use Disorder (TUD) is one of the most common substance use disorders in the world. Evidence-based treatment of TUD is effective, but treatment accessibility remains very low. A dearth of specially trained clinicians is a significant barrier to treatment accessibility, even within systems of care that implement brief intervention models. The treatment of TUD is becoming more complex and tailoring treatment to address new and traditional tobacco products is needed. The Council for Tobacco Treatment Training Programs (Council) is the accrediting body for Tobacco Treatment Specialist (TTS) training programs. Between 2016 and 2019, n = 7761 trainees completed Council-accredited TTS training programs. Trainees were primarily from North America (92.6%) and the Eastern Mediterranean (6.1%) and were trained via in-person group workshops in medical and academic settings. From 2016 to 2019, the number of Council-accredited training programs increased from 14 to 22 and annual number of trainees increased by 28.5%. Trainees have diverse professional backgrounds and work in diverse settings but were primarily White (69.1%) and female (78.7%) located in North America. Nearly two-thirds intended to implement tobacco treatment services in their setting; two-thirds had been providing tobacco treatment for 1 year or less; and 20% were sent to training by their employers. These findings suggest that the training programs are contributing to the development of a new workforce of TTSs as well as the development of new programmatic tobacco treatment services in diverse settings. Developing strategies to support attendance from demographically and geographically diverse professionals might increase the proportion of trainees from marginalized groups and regions of the world with significant tobacco-related inequities.

A Study of the air routes of the world brings out almost at once the fact that some of the most difficult route are also the most attractive. For instance, the North Atlantic route which couples North America with Europe is certainly one of the most difficult in the world, but also by the fact that it couples two of the most densely populated, as well as the most wealthy groups of people in the world, one of the most attractive.

AbstractMany glaciers in Svalbard and in other glacierized areas of the world are known to surge. However, the time series of observations required to assess the duration of fast motion is very restricted. Data on active-phase duration in Svalbard come from aerial photographs, satellite imagery, field surveys and airborne reconnaissance. Evidence on surge duration is available for eight Svalbard ice masses varying from 3 to 1250 km2. Worldwide, active-phase duration is recorded for less than 50 glaciers. Few observations are available on high polar ice masses. The duration of the active phase is significantly longer for Svalbard glaciers than for surge-type glaciers in other areas from which data are available. In Svalbard, the active phase may last from 3 to 10 years. By contrast, a surge duration of 1–2 years is more typical of ice masses in northwest North America, Iceland and the Pamirs. Ice velocities during the protracted active phase on Svalbard glaciers are considerably lower than those for many surge-type glaciers in these other regions. Mass is transferred down-glacier more slowly but over a considerably longer period. Svalbard surge-type glaciers do not exhibit the very abrupt termination of the active phase, over periods of a few days, observed for several Alaskan glaciers. The duration of the active phase in Svalbard is not dependent on parameters related to glacier size. The quiescent phase is also relatively long (50–500 years) for Svalbard ice masses. Detailed field monitoring of changing basal conditions through the surge cycle is required from surge-type glaciers in Svalbard in order to explain the significantly longer length of the active phase for glaciers in the archipelago, which may also typify other high polar ice masses. The finding that surge behaviour, in the form of active-phase duration, shows systematic differences between different regions and their environments has important implications for understanding the processes responsible for glacier surges.

AbstractThe phenomenon of mass surveillance has confronted legal systems throughout the world with significant challenges to their fundamental norms and values. These dilemmas have been most extensively studied and discussed in relation to the kind of privacy cultures that exist in Europe and North America. Although mass surveillance creates the same kinds of challenges in Muslim countries, the phenomenon has rarely been discussed from the perspective of Shari’a. This article seeks to demonstrate that this neglect of mass surveillance and other similar phenomena by Shari’a scholars is unjustified. Firstly, the article will address objections that Shari’a does not contain legal norms that are relevant to the modern practice of state surveillance and that, if these exist, they are not binding on rulers and will also seek to show that, whatever terminology is employed, significant aspects of the protection of privacy and personal data that exists in other legal systems is also be found deeply-rooted in Shari’a. Secondly, it will assess the specific requirements that it makes in relation to such intrusion on private spaces and private conduct and how far it can benefit from an exception to the general prohibition on spying. Finally, it is concluded that mass surveillance is unlikely to meet these Shari’a requirements and that only targeted surveillance can generally do so.

HIV infections are prevalent among adolescents and young adults, of whom 44% remain unaware of their diagnosis. HIV screening presents numerous challenges including stigma, fear, and concerns about confidentiality, which may influence young people’s acceptance of HIV screening and linkage to care differently from individuals in other age groups. It is imperative to understand which care delivery models are most effective in facilitating these services for youth. This systematic review analyzes the rates of HIV test acceptance and linkage to care by care delivery model for adolescents and young adults. Studies were classified into emergency department (ED), primary care/inpatient setting, community-based program, or sexually transmitted infection clinic models of care. From 6395 studies initially identified, 59 met criteria for inclusion in the final analyses. Rate of test acceptance and linkage to care were stratified by model of care delivery, gender, race, age ranges (13–17, 18–24 years) as well as site (North America vs rest of the world). A significant difference in acceptance of HIV testing was found between care models, with high rates of test acceptance in the ED setting in North America and primary care/hospital setting in the rest of the world. Similarly, linkage to care differed by model of care, with EDs having high rates of linkages to HIV care in North America. Future studies are needed to test mechanisms for optimizing outcomes for each care delivery model in addressing the unique challenges faced by adolescents and young adults.
