Sidelobes
Sidelobes are the unwanted electromagnetic waves that leak out from the edges of a beam of radio waves or other waves, such as acoustic or light waves, that are subtly directed at a particular point. Sidelobes are strong enough to reach the intended target at a different frequency from the desired one, yet they fail to achieve the dense damage that the desired beams could.
Siderate
Considerate; be considerate.<br><br>Example: "He was a siderate friend who always made sure to call me on my birthday."
Siderated
I assume you meant "considerate".<br><br>Considerate: having or showing a tendency to think about the needs or feelings of others; taking into account the effects of one's actions on others.
Sideration
Consideration, careful thought and attention given to someone or something before making a decision.
Sidereal
Relating to or measuring the stars in the sky; used to describe a day that begins at midnight and lasts for 24 hours, reckoned by the stars rather than the sun.
Siderian
Siderian refers to the earliest time period in Earth's history, corresponding to the Eoarchean to the Statherian eons, from approximately 4 billion to 2.5 billion years ago. <br><br>It is the first eon within the Precambrian era, characterized by the Earth's surface being largely devoid of oxygen, with the atmosphere composed of methane, ammonia, and other gases, and iron-rich crust. The term "siderian" was coined from the Greek "sideros," meaning iron, due to the high iron content of the rocks of this era.
Siderite
Siderite is a mineral species that is an iron carbonate mineral with the chemical formula FeCO3. It has a trigonal crystal system and is typically found in sedimentary rocks, often in association with other minerals such as calcite and quartz. Siderite is named after the German word for iron, "sideros." It is also known as iron spar. In dermatology, siderite can also refer to a rare but harmless skin condition characterized by small, red lesions that resemble rust spots.
Sideritis
Sideritis, also known as "ironwort", is a type of flowering plant in the mint family. It is native to the Mediterranean region, and is found in a wide range of environments, including rocky areas and mountainous terrain.
Sideroblast
A sideroblast is a mature red blood cell that contains granules of iron, called ferrosomes, which accumulate around the nucleus. This is a normal part of the process of red blood cell production in the bone marrow, but excessive sideroblasts can be a sign of certain disorders, such as sideroblastic anemia or anemia of chronic disease.
Sideroblastic
Sideroblastic refers to a type of anemia characterized by the production of red blood cells that accumulate abnormal amounts of iron within the mitochondria. This results in the appearance of "ring sideroblasts" under a microscope, which is a hallmark of the condition.<br><br>In general, the term "sideroblastic" can also refer to any cellular or tissue defects or processes related to the metabolism of iron, particularly in the context of hematopoiesis (the formation of blood cells).
Sideroblastosis
Sideroblastosis is a rare genetic disorder that affects the production of healthy red blood cells in the bone marrow. It is characterized by the presence of ring sideroblasts in the bone marrow, which are immature red blood cells that contain iron, but are unable to mature and function properly.<br><br>In sideroblastosis, the body is unable to properly utilize iron, which typically plays a crucial role in the production of hemoglobin, the protein in red blood cells that carries oxygen to tissues. As a result, iron builds up in the bone marrow, forming ring sideroblasts.<br><br>There are several types of sideroblastosis, including:<br><br>1. Hereditary X-linked sideroblastosis: This is the most common type, which is inherited in an X-linked recessive pattern. This means that the faulty gene responsible for the condition is located on the X chromosome and is more common in males, who have only one X chromosome.<br>2. Refractory anemia with ring sideroblasts: This is a subtype of myelodysplastic syndrome, a group of disorders characterized by faulty blood cell production in the bone marrow.<br><br>Symptoms of sideroblastosis may include:<br><br> Fatigue<br> Pale skin color<br> Shortness of breath<br> Dizziness or lightheadedness<br> Abdominal pain<br> Joint pain<br> Hair loss<br> Skin pigmentation changes<br><br>Treatment of sideroblastosis may include medications to manage symptoms, as well as transfusions of red blood cells to increase oxygen delivery to tissues. In some cases, stem cell transplantation may be an option to treat the disease.
Sideroblasts
Sideroblasts are a type of cell in the bone marrow that are involved in the production of red blood cells. They are characterized by the presence of iron particles (sideroblasts are a Greek word meaning "iron granules") in their mitochondria, which is a precursor to the hemoglobin in red blood cells. These cells form when the normal process of heme synthesis is disrupted, leading to the accumulation of iron within the mitochondria. Sideroblasts are often seen in conditions such as sideroblastic anemia, flash smoking, and lead poisoning.
Siderocyte
A siderocyte is an abnormal red blood cell (erythrocyte) that contains abnormal amounts of iron, often found in cases of sideroblastic anemia. These cells are characterized by the presence of accumulations of iron in the mitochondria of the cell, forming small, darkly staining granules or aggregates known as siderosomes. This results in an abnormal blue color within the cell, making the siderocytes appear as if they have "sidero" (Greek for "iron") in them. Siderocytes are larger than normal erythrocytes and are often seen in individuals with conditions that affect hemoglobin production, such as lead poisoning, electrolyte imbalances, or various myeloproliferative disorders.
Siderographist
A siderographist is an astrologer who uses a siderograph, a device used to represent the positions of the stars on a plane tangential to the celestial sphere, to determine the positions of the stars and planets in relation to the zodiac and other celestial bodies.
Siderolite
A type of sedimentary rock that is composed of Hře grains of siderite (an iron carbonate mineral).
Sideromancy
Sideromancy is a form of divination that uses the study of the positions of the stars and planets, particularly the movements of the Sun, Moon, planets, and other celestial bodies in the sky, to gain insight or guidance into a particular situation or question.
Sideropenia
Iron-deficiency anemia; a condition due to the failure of the body to absorb sufficient iron, leading to a decrease in the production of hemoglobin.
