Indoor air quality and human health are of continuously growing importance. Indoor air quality may be affected by many factors excluding, but not limited to, more loosely sealed buildings, the use of air purifiers and other pollutant sources (for example, room air fresheners), the use of various chemicals for pesticide management and cleaning, and finally, the use of synthetic building materials and furnishings. In recent years, people have become more aware of potential health and comfort problems that may be associated with poor indoor air quality. It is partly due to the move to more tightly sealed buildings, the implementation of energy conservation programs, and the growing use of laser printers, photocopiers, and other sources of indoor air contamination. Greater general awareness of environmental issues may also play a part. Most IAQ complaints from building occupants are related to a respiratory headache, irritation, odours, or fatigue. These concerns may be associated with chemical vapours, dust generated in the work environment, contaminants associated with fungal growth (mould), materials infiltrating from outside sources (such as pollen or engine exhaust), or other factors such as elevated carbon dioxide levels. This handbook aims to turn the attention to these subjects and to promote methods and technologies to reduce poor indoor air quality and to distribute outdoor air throughout the building, remove contaminants and odours, and control the indoor temperature and humidity. The information in this guide will help to maintain good indoor air quality in a building, prevent indoor air quality problems, and correct issues that may arise. It will also help to understand the indoor air quality requirements. The structure of this text allows for flexibility in course content and design. It may be used equally well either as a textbook for students or a handbook for environmental consultants, mechanical engineers, building occupants, labour unions and suppliers. Furthermore, this text may be useful data for either the undergraduate or the graduate level. The author wishes to acknowledge Nova Science Publishers with special mentions to Nadya S Gotsiridze-Columbus and Carra Feagaiga for their editorial support.

Metals are important environmental pollutants and their toxicity is a problem of increasing significance for ecological, nutritional, and environmental reasons. These pollutants, ultimately derived from a growing number of diverse anthropogenic sources (industrial effluents and wastes, urban runoff, sewage treatment plants, boating activities, agricultural fungicide runoff, domestic garbage dumps, and mining operations), have progressively affected more and more different ecosystems. Even agricultural lands are progressively becoming enriched of metals due to long-term use of phosphatic fertilizers, sewage sludge application, dust from smelters, industrial waste and bad watering practices in agricultural lands. Among these metals, Cu, Fe, Mn, Mo and Zn are pivotal micronutrients, while Ag, As, Cd, Cr, Hg, Pb, Sb and V and are non-essential for plants and have no known function as nutrients and seem to be more or less toxic to all plants and microorganisms. Sodium excess deserves particular attention. Several agricultural lands are indeed becoming familiar with the problem of salinization, due to the use of fresh water which contains a high level of NaCl or due to intensive fertilization, especially in arid and semi-arid environments characterized by poor rainfalls. Overall, the presence of both essential and non-essential metals in the atmosphere, soil and water, in excessive amounts, can cause serious problems to all organisms. Knowledge of plant-metal interactions is important for the safety of the environment, but also for reducing the risks associated with the introduction of trace metals into the food chain. Although intense research has been conducted during the last 30 years, many aspects remain to be clarified concerning the effect of metals in higher plants. Our goal for this book is to critically review existing literature related to the specific effects of different metals in plants, as well as to provide new evidence about plant-metal interactions in order to clarify mechanisms of metal uptake, translocation, and partitioning and the effect of metal toxicity. Consequences related to accumulation of metals in food products have been described. Physiological and biochemical mechanisms adopted by plants to cope with metal excess and possible implications for phytoremediation of metal-contaminated soils are also discussed. Therefore, we believe that this book will provide a comprehensive overview regarding some aspects of metal toxicity in plants and it will be useful for scientist working in this field of research, but it will also be of practical interest to environmentalists, policy-makers, and resource managers working on the topic. We wish to thank all the authors who joined this book project by contributing their valuable work. Lastly, we extend our sincere thanks to Nova Science Publishers for their efficient support.

The Italian Campaign is truly an amazing, and often heartbreaking, story, and it certainly generates sympathy as well as respect for the soldiers who fought there, particularly the sacrificed Texas and Polish soldiers as well as the British "D-Day Dodgers." In addition to the British soldiers, you gain a new and far greater appreciation of the men in the 36th Texas and Polish Divisions because of their commitment, heroism and sacrifice in these battles, much less the many others from multiple nations who fought in Italy in 1943 and 1944. This book is the first title in the NOVA Science Publishers Homeland Security Series presenting a walking tour of World War II battle sites in mainland Italy: 1. A Walking Tour of Italy's WWII Battlefields: From the Salerno Landings to San Pietro Infine 2. A Walking Tour of Italy's WWII Battlefields: Breaking the Gustav and Hitler Lines 3. A Walking Tour of Italy's WWII Battlefields: From the Anzio Landings to Rome. These books were derived from the sights and sounds I experienced while on Marty Gane's South Mountain Expeditions tour called WWII Invasion of Italy: From Sicily to Rome, which she conducted in September 2014. The late Edwin Cole Bearss was the lead South Mountain historian for the tour, and helped select our expert history guide British Lt Col (Retd) Frank de Planta de Wildenberg, a deservedly renown Italian battlefield tour leader. Franks designed the tour route, providing the specific strategic and tactical on-the-ground details we experienced at each stand (tour location) we visited. Ed Bearss provided insightful color commentary and likened situations to his own combat experience as a Marine in the WWII Pacific theater. This book provides the images and narration of Frank and Ed as we were taken from the Allied seaborne landings at Salerno to the fights for the high ground surrounding the beachhead to the devastation wrought at San Pietro Infine, the subject of a well-known period film by John Houston. During the development of the Ed Bearss memoir trilogy books (see Footnote 7 above), I created the preliminary Italian tour history that has been reviewed, vastly improved and supplemented by Frank de Planta, necessarily and deservedly the book's first author. Working with someone like Frank de Planta, as with both Ed Bearss and Barney Nolan in their memoirs, has proven (almost) as enjoyable as touring the Italian battlefields. Creating this book series brought back many emotive sights, sounds, stories and emotions (unfortunately, not the food) I felt while on the tour. We hope it provides some sense of that experience for the reader. Many excellent academic books have been written explaining Italian battlefield events to the detail, and we include these books in Frank's exhaustive bibliography. However, this book brings the tour experience, being there on the ground, as close as possible to reality for the reader by showing you many images from where the armies fought and died to set Italy free and attack the "soft underbelly" of the Third Reich. Its purpose is to have the reader experience the tour as we did, incorporating images from the extensive video I took that September in Italy. It was hard to imagine the violence that happened there over 75 years ago. Our tour guide, Frank de Planta, with color commentary from Ed Bearss, provided an emotive and accurate explanation of the events, the scenes, and the sacrifice. We hope this book provides at least a fraction of the experience many on this tour experienced there.

Athletes: From Performance Analysis to Injury Prevention opens with a study aiming to assess innovative theoretical approaches for studying human opportunities in sports where maximum achievement is caused by modern technology. The authors discuss the macro- and micro-nutrient requirements that must be followed by the athlete, depending on the athlete's total daily energy expenditure, the type of sport, their gender and environmental conditions. Subsequently, the components of a proper bike fit are explored, focusing on the three interfaces a human has with a bike: foot-pedal, pelvis-saddle, and hands-handlebar. Equipment needs, bike anatomy, and the process of performing a bike fit are reviewed. Lastly, the authors propose to identify at-risk women's team sport athletes by identifying psychological perceptions of high vs. low injuries and/or fatigued athletes.

Dinoflagellates are fascinating protists, mostly unicellular, distributed in environments ranging from the polar to tropical seas, hypersaline, coastal, estuarine and oceanic waters. There are about 2,377 dinoflagellate species recognized. They exhibit a great diversity of shape, size, biochemical composition and physiological characteristics. Generally free floating, dinoflagellates are photosynthetic, a few species such as the Symbodinium are symbiotic, living in corals, while a few are parasitic. This volume presents a discussion on dinoflagellate phylogeny based on recent developments in molecular biology. It provides insights into the similarity of pigment composition with other microalgae. A comprehensive coverage of their carbon assimilation rates is presented, which appear to be low compared to other microalgae. Besides photosynthetic assimilation, an interesting aspect of acquiring carbon is through mixotrophy which appears to be wide spread amongst dinoflagellates and a thorough discussion is presented. Key features of this book include recent methods of culturing dinoflagellates, which can serve as analogues of their blooms in understanding their physiology, biochemistry and production of phycotoxins. This book, based on massive data collected over decades of research, provides an informative overview on the spatial and temporal distribution and dispersal of dinoflagellates by ocean currents, ballast water introductions and climate changes. About 70 species of dinoflagellates are implicated in the production of ephemeral harmful algal blooms (HABs), which are on the increase globally. Based on several case studies, a comprehensive coverage of the phycotoxins produced by HAB species (PSP, DSP, ASP, Ciguatera, NSP) is presented. The adverse effects of phycotoxins on human health, and the loss of revenues ($50 million in the USA) due to fish kills are evaluated. Latest advances in the methodology of genomics are presented with a view to highlight their importance and to understand their linkage with phycotoxin production. A discussion of remediation measures to manage HABs is presented, which would be highly useful in aquaculture operations. This book provides a large number of illustrations, microphotographs and color photographs. It is ideal for any audience requiring an in-depth exposure to current issues, ideas and methods used in dinoflagellate studies. The topics discussed serve as a useful reference to researchers, scientists, environmental managers, undergraduate and graduate students.
