Vimal Karani

Dr. Vimal Karani is an Assistant Professor in Nutrigenetics at the University of Reading, UK. His primary research interests focus on the investigation of gene-nutrient interactions on metabolic- and cardiovascular disease- related outcomes using combined approaches from genetic epidemiology, statistical genetics and molecular biology. His long term goal is to use the findings from observational studies to carry out human intervention studies aimed at developing industrial collaborations to facilitate ‘Personalized Nutrition’. Dr. Vimal visited SQU as part of his PhD student’s research program, where he will be involved in conducting a population based study on genes and dietary patterns among Omanis with a view towards preventing obesity in Oman.

Horizon: Could you explain the research project that your PhD student is going to carry out in Oman?

Dr. Vimal: It comes under the relatively new branch of medical science called nutrigenetics which aims to identify genetic susceptibility to chronic diseases and genetic variation in the effects of nutrient intake on the genome.

My student at the University of Reading, who is an Omani, plans to conduct a population based study which will look at the genetic determinants and dietary patterns of the Omani people. By coordinating with 23 health centers in different parts of Oman and students at the SQU, we plan to collect genetic data of 1500 Omani people and look at the prevalence of obesity, overweight susceptibility to cardiovascular disease and type 2 diabetes. The basic idea is to examine the gene-diet interactions. The main objective of the study is to develop public health strategies for implementing personalized nutrition program in Oman. By assessing the genetic data and dietary patterns, dieticians will be in a better position to advice the people if modifying the diet can help overcome various health conditions such as obesity and overweight and their consequences. The study will examine the possibility of modifying the eating habits based on the genetic information collected.

Horizon: What different data collection methods will be used in this study?

Dr. Vimal: The identification of the necessary genotype is carried out by means of a blood analysis. Subsequently, the DNA is analyzed in different ways. The goal of the study is to identify if there are genes that make individuals more susceptible to obesity and obesity-related diseases in Oman. In the long run, nutrigenetics should allow nutritionists and physicians to individualize health and diet recommendations. Consequently, preventive medicine, diagnostics and therapies could be optimized. We hope that in the near future people will be able to receive personalized nutrition recommendations based on their genetic makeup to prevent chronic illnesses down the road such as cardiovascular disease and diabetes, known as polygenic diseases.

Horizon: What is your primary assessment of the dietary pattern among

Omanis?

Dr. Vimal: There should be a balance between the amount of food being consumed by an individual and the amount of energy released by the body through physical activities. During my stay in Oman for three to four days,

I noticed that there is tendency for high consumption of carbohydrates and protein among the Omani people. The amount of physical activity is less as compared to the high intake of carbohydrate and protein rich food. I feel that there is a lack of awareness among the people on the risks associated with unbalanced dietary habits and lack of physical activities.

Horizon: Could you explain the long term usefulness collecting genetic data of Omani population and your nutrigenetics study in Oman?

Dr. Vimal: Nutrigenetics, which is otherwise calledor nutritional genetics, is expected to pave the way towards preventive medicine and improved public health. Nutrigenetic testing in the Omani population will offer insights into an individual’s risk for disease, and provide data that allows dietitians to personalize nutrition interventions. The potential for this field of research is huge, but the full potential may not be realized for a very long time because of the complexity of the gene-lifestyle interactions on obesity. While the potential clinical applications of nutritional genetics are exciting, it is very important to realize that nutrigenetic analysis will not give a yes or no answer. Rather, the testing will give information on who is more or less likely to develop obesity, or who is more or less likely to benefit from a particular nutrition intervention. However, this information will be useful for the Omani population to modify their diet depending on their genetic make-up.

Horizon: Now you are associating with the Food Science and Nutrition Department of Sultan Qaboos University for this study? Are you looking for wider collaboration with any of the national authorities in Oman?

Dr. Vimal: Although the collaboration is with the department of Food Science and Nutrition, the study is basically funded by the Ministry of Higher

Education. Also, the study is supported by the Ministry of health, which is involved in the ethical approval of research activities in Oman. Furthermore, we are intending to perform genome-wide scans for identifying novel genes for obesity in the Omani population, for which a grant application will be submitted to The Oman Research Council (TRC) in 2015/2016. Given that this will be the first large-scale genetic study that is being conducted in 23 health centers and SQU and also the first to implement personalized nutrition program, we would certainly need support from other national authorities in Oman.

A Balanced Approach

English has been well accepted in Oman’s social, economic and educational spheres. English, as a global language, has acquired a momentum and vitality of its own and has helped in promoting the Omani culture in many ways. The people of this country has no elevated sense of fear that globalization and the spread of English use might endanger Omani cultural identity. Omani students learn English language as it is a school subject and is needed in higher education. Learning English helps students to get better grades in school and securing good employment after graduation.

A research has found that equipping Omani women with English fosters their sense of identity and affords them a feeling of freedom and confidence. Omani government and policy makers have supported the use of

English in different domains due to the realization that English is an essential tool for the advancement of the country and its integration with the rest of the world. Now English language has become a medium to promote

Oman and its culture by promoting intercultural communication between

Omanis and the rest of the world.

The widespread use of English language has played a key role in transcending Omani locality and moving towards universality while maintaining its unique cultural identity. As Dr. Rahma Ibrahim Al-Mahrooqi and Dr. Victoria Tuzlukova, English language researchers at SQU, rightly point out in their book chapter “Bringing the Global and the Local Together

Through English in Oman”, a process of ‘glocalization’ has taken place in Oman, and English has helped in the process of domesticating what is foreign to the local taste.

Oman is also taking part in a regionalization process by consolidating its relationships with other Gulf countries that are dependent to a great extent on foreign labor, a fact that calls for the use of English since it is the language of international communication. English has helped in promoting the country worldwide. The presence of foreign labor force, promotion of tourism, and higher studies abroad, all call for the use of English language as the second language in Oman after the mother tongue Arabic. However, some experts are concerned about the rise of English as a lingua franca throughout the Arab world and the consequent decline of Arabic. In this context we should tell our students not to excommunicate from our own language and culture.

Technologies for Minimally

Processed Foods

Springer, New York, recently brought out a book titled “Minimally

Processed Foods: Technologies for Safety, Quality and Convenience” co-edited by Prof. Shafiur Rahman from the Department of Food Science & Nutrition, College of Agricultural & Marine Sciences, Sultan

Qaboos University, and Dr. Wasim Siddiqui from Bihar Agricultural

University, India. This is the ninth book of Prof. Shafiur Rahman, who has extensive research and teaching experience in food processing and related fields.

Dr. Wasim Siddiqui Prof. Shafiur Rahman

Commenting on the latest book, Prof. Rahman said: “Earlier foods are usually prepared at home in the kitchen. Industrialization of the society has introduced the diversified concepts of restaurants since people don’t have enough time to prepare their meals for families or social gatherings. This trend was followed by take-away shops that sold fast foods (such as sandwiches and burgers). Over the past

Panorama

decades, consumers want fresh like foods with nutritive values and the preferred sensory attributes such as ethnic flavor, odor, flavor, texture and taste. In order to address these demands, minimally processed foods (i.e. minimum preparation required), such as fresh-cut, ready-to-serve, ready-to-eat, ready-tocook, cook-chill, cook-freeze and part-baked, are being introduced in the market. The main advantages of these meals are that they are easy and quick to prepare, healthy and possess ethnic flavors with varied shelf-life. The convenience of microwaves in the kitchen has resulted in the popularity of these types of products. This new book addresses all aspects of minimally processed foods first time”.

According to Prof. Rahman, the safety and efficacy of minimal food processing depends on the use of novel preservation technologies. “This book first examines what is meant by minimally processed food, including fresh-cut, cook-chill, ready-to-eat meat and part-baked products. It then explores the technologies or methods to produce quality products in terms of safety and nutrition, including edible coating, natural preservatives (antimicrobial, flavor enhancer, anti-browning), advanced packaging (active, antimicrobial, and modified or controlled atmosphere) and selected non-thermal techniques (high pressure, pulsed electric field, ultrasound, light). Preservation of food is crucial to achieve a secure and safe global food supply with the desired sensory quality. In addition, the increasing consumer demand for safe, ready-to-serve, ready-to-eat-cook products with minimal chemical preservatives has raised expectations.

However, foods minimally processed, such as freshcut fruits and vegetables, cook-chill and half-baked foods, are delicate products that require special care in preparation, processing, storage and handling. As a result, new technologies to develop minimally processed foods have aggressively advanced”, he added.

The book contains 12 chapters and the first chapter determines/describes the scope of the minimally processed foods and available new technologies or methods to produce quality products in terms of safety and nutrition. Chapter 2 presents hurdle concepts in food preservation and processing.

Chapter 3 has devoted to basic principles and methods of packaging required for minimally processed foods. Chapters 4 and 5 are well versed with important operations (i.e., washing, peeling, and cutting) and technologies (traditional and novel) involved in manufacturing of plant-based fresh-cut products.

Chapter 6 concisely describes the trends, convenience, and safety issues of ready meals. Three chapters

7 – 9 are dedicated to processing, quality, and storage issues of these products. Nowadays, the production and processing of meat and fish products without compromising safety and quality is a challenge. The chapters 10 and 11 deal with various conventional and latest minimal processing approaches used in meat and seafood products. Finally, the chapter 12 discusses the important issues of minimal processing in terms of the sustainability and challenges along with remedial measures to preserve the quality and safety of minimally processed foods.

The editors are confident that this book will prove to be a standard reference work for the food industry in developing minimally processed foods. The information can be used to extend the shelf life by retaining safety as well as nutritional and sensory quality. The editors would appreciate receiving new information and comments to assist in the future development of the next edition.

News Round Up

“Cooperation Day” Focuses on Field Training

In order to boost cooperation with various ministries, government bodies and private sector organizations, and streamline training opportunities for students in these organizations, Sultan Qaboos University, today organized

“Cooperation Day” under the patronage of H.H. Sayyidah Dr. Mona bint

Fahad Al Said, SQU Assistant Vice Chancellor for International Cooperation. The event carried the theme “field training, a partnership between the university and government and private sector institutions”. Senior officials from various government and private organizations, and academicians responsible for training and community services at various colleges of the university participated in various panel discussions organized as part of the “Cooperation Day”.

Speaking on the occasion, Dr. Mona Al Said, said that SQU was keen to foster cooperation with the government institutions and the private sector to achieve one of the significant objectives of this university, i.e., training its graduates and preparing them for the labor market. “We thank you for your efforts and cooperation in providing an appropriate training environment for our students and preparing them for the labor market. We look forward, at the same time, that our meeting today will proactively initiate a new beginning of cooperation, adding to your esteemed efforts in supporting our students”, she said.

The Assistant Vice Chancellor called upon the participants to discuss the challenges and difficulties that may accompany the training programs for the students, in addition to the challenges and observations that the officials would like to share from their direct involvement in training our students.

“We also wish to discuss the possibility of providing more training opportunities and adopting an effective strategy for training the university students based on your previous experiences”. Elaborating on teaching and research at SQU, Dr. Mona Al Said SQU is home to more than 18000 students, more than 16000 are in the undergraduate level, divided into 80 Bachelor Programs, and 4 Diploma Programs. “It is also home to more than 1200 students at the postgraduate level, divided into 70 seventy Master Programs and 29 Doctoral Programs. The number of approved research projects at the university reached more than 1800, which are funded with approximately

50 million Omani Rials”, she said.

Speaking on the occasion, Mohammed Ahmed Al Riyami, Senior Manager,

HR-Career Planning at Omantel, said that training of university and college students poses many challenges that are not limited to the educational institutions but also include sectors that train these students. “One of the biggest challenges that the private sector faces is the growing demand of training students in a short period which is during the summer break. This challenge can possibly affect the quality of training provided to these students because of the large number of trainees who seek training opportunities at the same time and in the same place”, he said. The program included three panel discussions led by officials from the private sector and academicians from various colleges at SQU who look after student training.

First PhD Thesis on Harmonic Analysis in Oman

Khadija Al Balushi, a doctoral graduate from the Department of Mathematics and

Statistics at the College of Science, has generated the first PhD thesis on harmonic analysis in Oman. The thesis titled “Integral operators with homogeneous kernels” deals with the boundedness of various types of integral operators with homogeneous kernels. Integral operators with homogeneous kernels are important part of harmonic analysis. There applications spread over many branches of mathematics and related fields such as partial differential equations, complex analysis and potential theory. During the last 15 years, a significant development of the theory of integral operators with homogeneous kernels has occurred. The presence of rough kernels and the type of singularities are among the main features of this theory. conditions. She established the boundedness results for singular integral operators along surfaces of revolutions determined by certain polynomial mappings and flat curves. Also, she discussed the boundedness of maximal functions that are related to singular integral operators which carry oscillatory factors in their kernels.

The Marcinkiewicz integral operators also appeared in her work. However, she extends a recent result given by AL-Salman in 2012 to the case when the operators are associated to the surfaces determined by functions satisfying certain growth conditions and kernels satisfy Grafakos and Stefanov conditions. In addition, Khadija has considered parametric Marcinkiewicz integral operator on the product spaces. The obtained results extend and improve some earlier results established under Grafakos-Stefanov conditions.

A significant part of this development has been achieved by Prof. Ahmad

Al-Salman, the supervisor of the thesis. Al-Salman is one of the well known experts in this subject. In her thesis, Khadija Al Balushi has made significant contributions. As a consequence of her hard work, she could prove many results. In particular, she proved the boundedness of certain classes of singular integral operators whose kernels satisfying Grafakos-Stefanov

In conclusion, the results obtained in the thesis are original. It is worth noticing here that some of the obtained results have been already cited by other mathematicians. This definitely, shows the importance and significance of the obtained results. In fact, they pave the way for further study in this area. The study carried out by Dr. Khadija Al Balushi is unique in the Sultanate of Oman. It is the first Ph.D thesis in the subject of harmonic analysis in Oman. The many problems discussed in the thesis open the door for future research by other mathematicians in Oman as well as in the mathematical community.

Insight

SQU Invention to Reduce

Enhanced Oil Recovery Costs

In the Sultanate of Oman, there are still large remaining oil reserves that require implementation of the technically more challenging (EOR) applications processes. One EOR method for light oil reservoirs that has proven success in different parts of the world is Carbon Dioxide (Co2) injection. CO2 injection could be very beneficial in reducing residual oil saturation levels, for its higher oil ultimate recovery and for its use in the Carbon Capture and

Storage (CCS) that leads to desirable benefits on the environment. Determining CO2-oil Minimum Miscibility Pressure (MMP) is the key parameter for the design and operations of successful CO2 miscible flood project. The miscibility with the oil at injection pressure of MMP occurs at CO2 supercritical conditions, which is the optimum condition to become an efficient solvent.

Commenting on his achievement, Dr. Khalid Al

Hinai said: “The newly built SQU RBA system has more advantages as compared to the existing industry RBA system. The apparatus satisfies the thermodynamics behavior required for the CO2 miscibility in the oil is satisfied. In addition, the SQU RBA

System is less expensive than those available in the market and the resulting cost saving is tremendous.

The built SQU RBA system is the first gas-oil miscibility apparatus in Oman and it provides accurate measurements of gas-oil MMP. This was achieved with no additional costs or at minimal costs and it can be used in Oman and worldwide”.

As part of a research conducted at the College of Engineering at Sultan Qaboos University, Dr. Khalid

Al Hinai, a researcher, has developed a new Rising

Bubble Apparatus system which can increase the efficiency of enhanced oil recovery from Omani oil fields. His research study outlines the method of predicting CO2-oil MMP for different Omani light oil reservoirs. The method used in this research study involved two parts. The first phase consisted of the experimental work based on the newly built

SQU Rising Bubble Apparatus system experiments to measure CO2-oil MMP for different Omani light oils reservoirs and the second phase of the research study contained the development of a mathematical model based on the resulting MMP values obtained from the experimental work in the first phase. Dr.

Khalid Al Hinai developed and constructed the apparatus successfully in the most cost effective way, at SQU Petroleum Engineering Research Laboratory, with limited resources that required large amount of efforts and engineering thinking.

In this research study, mathematical models to predict the CO2-oil MMP were developed for the

Omani light oil reservoirs. Accurate predictions of

CO2-oil MMP were achieved by using the newly developed Particle Swarm optimization (PSO) and

Artificial Neural Network (ANN) models of CO2-oil

MMP for the Omani oil samples than the literature models predictions. An advantage to the newly developed PSO and ANN models that they are general models and they are capable of being applied for

Oman light oil reservoirs and worldwide oil reservoirs.

The newly developed CO2-oil MMP PSO and ANN mathematical models for the prediction of the CO2oil MMP, provide a fast and less time consuming method for the screening of potential Omani light oil reservoirs for CO2 flooding as an efficient EOR

Tropical Cyclones and Biological

Productivity of the Ocean

A research team led by Dr. Sergey Piontkovski from the Department of Marine Science and Fisheries at SQU, has been involved in studies of the ecology of atmospheric cyclones. Tropical atmospheric cyclones are important elements of the ocean-atmosphere interaction responsible for significant cooling and vertical mixing of the upper layers of the ocean. Every year, about 80 tropical cyclones (with wind speeds above 17 m s-1) form in the world’s ocean and affect physical, chemical, and biological processes in the upper mixed layer. The cyclones with maximal wind speed exceeding 33m s−1 are known as typhoons in the Pacific Ocean and as hurricanes in the

Atlantic and Indian Ocean.

two-fold, whereas the translation speed of cyclones and the chlorophyll ratio (characterizing chlorophyll concentration before and after cyclone passage) varied by tenfold. It was shown that cyclones affecting the phytoplankton community approaching its seasonal production maximum could not stimulate further increase of chlorophyll-a concentration (due to explicitly available nutrients) or this stimulation results in a weak response. Controversially, cyclones affecting the community approaching the “bottom” of seasonal cycle could cause gradual increase of chlorophyll-a concentration.

A negative type of relationship between chlorophyll ratio and translation speed of cyclones was evaluated. In the range of translation speeds from 1 to 10 ms-1, the exponential increase of chlorophyll-a concentration due to cyclone passage was mostly pronounced for slow moving cyclones.

Devastating consequences of the hurricanes and typhoons have reportedly reached billions of dollars in reparation of damages and tens of thousands in deaths. In terms of biological consequences, the cyclone wind field causes local mixing resulting in the injection of nutrients into the upper layer of the ocean and inducing the phytoplankton bloom. In some cases, the magnitude of the cyclone-induced bloom could reach gradual level, in terms of primary production. Overall, the information on how cyclones modify biological productivity of the ocean is yet to be integrated and a fundamental concept is yet to be proposed, on how the wind speed of cyclones, the translation speed, and the magnitude of induced bloom are related. The team was aimed for the analysis of these relationships.

Remote sensing is one of the approaches broadly used in monitoring of tropical cyclones, as well as the phytoplankton blooms, for which the chlorophyll a concentration (green pigment in cells) is widely used as an indicator of phytoplankton biomass and biological productivity in general.

Remotely sensed wind speed, translation speed, atmospheric pressure, atmospheric precipitation rate, and chlorophyll-a concentration were used to verify the hypothesis that the response of the phytoplankton community to propagating atmospheric cyclones should be associated with the phase of the seasonal cycle of phytoplankton biomass and the translation speed of a cyclone.

In the case of cyclone “Gonu” which made landfall on the Omani coast on 5

June 2007, data on phytoplankton coastal sampling were analyzed. Overall, for the 9 cyclones investigated, the maximal sustained wind speed varied

Tropical Cyclones in the Indian Ocean

About 13% of the world’s tropical cyclones were reported in the northern part of the Indian Ocean. Cyclone Gonu, which made a landfall in the coast of Oman on 5 June 2007, was documented as the strongest cyclone ever recorded in the northern part of the Indian Ocean over the past 60 years.

Two days prior to the landfall, Gonu had intensified to a super storm with maximum wind speed of about 260 km/h becoming the first documented category 4 status cyclone in the Arabian Sea, as well as the first cyclone to traverse this basin. In another study, Dr. Sergey Piontkovski and Dr. Adnan

Al Azri, from the Department of Marine Sciences & Fisheries at SQU, had analyzed the response of Phytoplankton Biomass (chlorophyll a) to the passage of Gonu.

The study concludes that the concentration of the chlorophyll a (detected for some “color windows” in the atmospheric cloud mask) along the track of the tropical cyclone, Gonu, exceeded the background concentration in the adjacent regions. The enhanced concentration was observed over the final

(western) part of a track, corresponding to a super cyclone phase. The persistence of the enhanced concentration induced by the passage of Gonu did not exceed 1 month and did not reach the concentration range typical for the Omani coastal upwelling in summer, which is the season of the highest concentration of chlorophyll a due to the southwest monsoon.
