Introduction to malnutrition among children
Malnutrition refers to when a person's diet does not provide enough nutrients or the right balance of nutrients for optimal health. Causes of Malnutrition To help understand the causes of malnutrition, UNICEF developed a conceptual framework which remains a useful tool to help understand the causes of malnutrition. Acute malnutrition among children is consistently increasing even though overall malnutrition levels in Syria remain below emergency levels...
Insects and Ecosystem Function
In the past two decades, an increasing number of ecologists have started to investigate the importance of biodiversity for ecological processes such as energy flow and nutrient cycling, often referred to as 'ecosystem functioning'. Insects are a dominant component of biodiversity in terrestrial ecosystems and play a key role in mediating the relationship between plants and ecosystem processes. This volume is the first to summarize their effects on ecosystem functioning, focusing mainly, but not exclusively, on herbivorous insects. Renowned authors with extensive experience in the field of plant-insect interactions, contribute to the volume using examples from their own work. In addition to providing concise reviews of the field, this volume discusses in detail the advantages and disadvantages of various techniques of manipulating insect herbivory. Thus, the text provides both a theoretical basis as well as practical advice for future manipulative studies of biodiversity-ecosystem functioning.
Hydrogenosomes and Mitosomes : Mitochondria of Anaerobic Eukaryotes
"Hydrogenosomes and Mitosomes: Mitochondria of Anaerobic Eukaryotes" provides a summary of the current knowledge of these organelles, which occur in unicellular, often parasitic organisms, including human pathogens. The distribution of these organelles is broad, but they were detected primarily in an anoxic habitat or nutrient rich intracellular niche that permits life without the efficient energy generating system of typical mitochondria. Their common characteristic is that they lack the aerobic energy conservation system of typical mitochondria and that they are usually the site of the synthesis of iron-sulfur clusters, regarded as the only indispensable function of eukaryotic mitochondria.These mitochondria-related organelles exhibit a variety of structures and functions. This work describes properties such as protein import, structure, metabolism, adaptation, proteome and their role in drug activation and resistance. Further topics include the evolution and biogenesis of these organelles.
Handbook of nutrition and ophthalmology
The Handbook of Nutrition in Ophthalmology is the first general text on nutrition and eye health created for physicians, nutritionists, and researchers. Dr. Richard D. Semba provides important links between the epidemic of obesity and implications it has for eye disease and blindness. The volume addresses three broad themes throughout. The first is that a healthy diet as a major lifelong habit will likely have an impact on reducing a substantial portion of visual impairment and blindness. The second is that a historical perspective is essential to understanding current challenges in ophthalmology, medicine, and public health. The third theme is that many nutrients play a role in oxidative stress and inflammation, and this theory has emerged as a major underlying hypothesis in the pathogenesis of eye diseases.
Habitats and Biota of the Gulf of Mexico : Before the deepwater horizon oil spill ; Vol.2 : Fish resources, fisheries, sea turtles, avian resources, marine mammals, diseases and mortalities
The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. Nutrients and pollutants from coastal communities and dozens of rivers flow into the Gulf, including material from the Mississippi River watershed, which drains over one third of continental United States. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of the most significant include the Ixtoc I blowout in the Bay of Campeche in 1979 and the Deepwater Horizon Oil Spill in 2010.

Geological Approaches to Coral Reef Ecology
By reconstructing the ecological history of coral reefs, the authors are able to evaluate whether or not recent, dramatic changes to reef ecosystems are novel events or part of a long-term trend or cycle. The contributions examine the interacting causes of change, which include hurricane damage, regional outbreaks of coral-consuming predators, disease epidemics, sea-level rise, nutrient loading, global warming and acidification of the oceans. Crucial predictions about the future of coral reefs lead to practical strategies for the successful restoration and management of reef ecosystems.

Food lens = فود لينس
Food lens is an innovative application designed to revolutionize dietary management by leveraging advanced image recognition and nutritional analysis. The primary objective of this senior project is to develop a user-friendly tool that identifies various foods through a camera interface and provides detailed nutritional information. This application not only enhances the user's understanding of their dietary intake but also assists in achieving personalized health and fitness goals. The core functionality of Food Lens involves the integration of a robust image recognition system capable of accurately identifying a wide range of foods. Upon identification, the application retrieves comprehensive nutritional data, including calorie content, macronutrient distribution (proteins, fats, carbohydrates), and essential micronutrients (vitamins and minerals). This data is then seamlessly integrated into the user's dietary profile. Food Lens is designed to track the user's daily caloric intake and compare it against personalized recommendations based on age, gender, weight, height, and activity level. By maintaining a dynamic record of consumed foods, the application provides real-time feedback on the user’s nutritional progress. This feature is particularly beneficial for individuals aiming to manage weight, address dietary restrictions, or improve overall health.
Food - drug interactions
The effect of drug on a person may be different than expected because that drug interacts with another drug the person is taking (drug-drug interaction), food, beverages, dietary supplements the person is consuming (drug-nutrient/food interaction) or another disease the person has (drug-disease interaction). A drug interaction is a situation in which a substance affects the activity of a drug, i.e. the effects are increased or decreased, or they produce a new effect that neither produces on its own. These interactions may occur out of accidental misuse or due to lack of knowledge about the active ingredients involved in the relevant substances. Regarding food-drug interactions physicians and pharmacists recognize that some foods and drugs, when taken simultaneously, can alter the body's ability to utilize a particular food or drug, or cause serious side effects.

Eutrophication of Shallow Lakes with Special Reference to Lake Taihu, China
Eutrophication and algal blooms are worldwide environmental issues in lakes. The eutrophication process and formation mechanisms of algal blooms are particularly complicated in shallow lakes due to the strong lake–land, air–water and water–sediment interactions. This volume features papers presented at the International Symposium on the Eutrophication Process and Control in Large Shallow Lakes – with Special Reference to Lake Taihu, a Shallow Subtropical Chinese Lake, held in Nanjing, China, 22–26 April, 2005. The topics include: physical processes and their effects on shallow lake ecosystems; biogeochemistry of sediments and nutrient cycling in shallow lakes; algal blooms and ecosystem response in shallow lakes; eutrophication control and restoration in shallow lakes; and resource exploitation, environmental protection and sustainable management in shallow lakes.
Eutrophication Management and Ecotoxicology
This book aims to bridge the gap between ecotoxicology and limnology. The intended readers of the book are water managers, policy makers with a scientific background as well as researchers/advisors in the area of water management. The book provides an ecotoxicological perspective on lake management and describes eutrophication of shallow, temperate lakes. It surveys the influence of toxic substances (e.g., agricultural pesticides) on the aquatic ecosystem, especially the relation between algae and daphnids. The message of the book is that nutrients such as phosphorus are not the only important factor in explaining and managing eutrophication: toxic disturbance of to-down control is also an important factor to be considered. The results of extensive studies and experiments (some unpublished) on lake eutrophication are presented in this book.
Eutrophication in the Baltic Sea : Present Situation, Nutrient Transport Processes, Remedial Strategies
This book takes a holistic process-based ecosystem perspective on the eutrophication in the Baltic Sea, with a focus on the factors regulating how the system would respond to changes in nutrient loading. This includes a very special process for the Baltic Sea: land uplift. After being depressed by the glacial ice, the land is now slowly rising adding vast amounts of previously deposited nutrients and clay particles to the system.
Environmental and Microbial Relationships
After the publication of Volume IV in 1997, the introduction of molecular methods into ecology led to significant new findings. Emphasizing these advances, the chapters for the second edition have been completely updated and revised. This volume provides insight into current research on fungal populations and communities. It focuses on fungal responses to the physical environment, interactions with other fungi, microorganisms and invertebrates, the role of fungi in ecosystem processes such as decomposition and nutrient cycling, and aspects of biogeography and conservation. Several chapters deal with various applications in, e.g. biological pest control, natural products discovery, and the degradation of toxic organic compounds. This is an invaluable source of information both for scientists who wish to update their knowledge of current progress and for graduate students interested in obtaining a first overview of this field of research.
