Cape Bojeador Lighthouse
Cape Bojeador Lighthouse, also known as Burgos Lighthouse, is a cultural heritage structure in Burgos, Ilocos Norte, that was established during the Spanish Colonial period in the Philippines. The lighthouse was first lit on March 30, 1892, and is set high on Vigia de Nagpartian Hill overlooking the scenic Cape Bojeador where early galleons used to sail by. After over 100 years, it still functions and serves ships that enter the Philippine archipelago from the north and guide them safely away from the rocky coast of the town.Burgos Ilocos Norte''. Pasyalan Ilocos Norte. Retrieved on April 23, 2010. The light marks the northwesternmost point in Luzon. The northeasternmost being Cape Engaño Lighthouse on Palaui Island, Santa Ana, Cagayan. The octagonal stone tower, the most prominent structure in the vicinity, can be seen from as far away as Pasuquin town in the south and Bangui on the east on a clear day.

Burgos, Ilocos Norte
Burgos, officially the Municipality of Burgos ( ilo, Ili ti Burgos; tl, Bayan ng Burgos), is a 5th class municipality in the province of Ilocos Norte, Philippines. According to the 2020 census, it has a population of 10,759 people. It was formerly known as Nagpartian and was renamed after the martyred priest José Burgos who was born in the Ilocos Region. It is home of the century-old Cape Bojeador Lighthouse. History The town was first known as Nagparitan, the early inhabitants were called Mumburi and known as a wild and fierce people who prevented the Christianized natives from settling in the vicinity. When the Spaniards came to the area, the people staged a revolt, captured the priest and mutilated his body. Because of this incident, the Spaniards change the name of Nagparitan, meaning prohibit, to Nagpartian which means the place of slaughter. On October 15, 1903, Nagpartian was then fused with the municipality of Bangui because of the unstable condition due to low collec ...

Mindoro Strait
The Mindoro Strait ( tgl, Kipot ng Mindoro) is one of the straits connecting the South China Sea with the Sulu Sea in the Philippines. It separates Mindoro Island from Busuanga Island (one of the Calamian Islands of Palawan Province). Located between the two islands is the Apo Reef, the largest coral reef system in the Philippines. The reef divides the strait into the Apo East Pass and the Apo West Pass.U.S. Corps of Engineers (1954)"San Jose (topographical map)" University of Texas in Austin Library. Retrieved on 2014-09-24. The Mindoro Strait is part of an alternate route for ships passing between the Indian and Pacific oceans and a common one for those exceeding the Malaccamax size and therefore being incapable of using the Strait of Malacca. Modern bathymetric soundings have shown that the centers of the Mindoro Strait and the Sibutu Passage are both deep enough that they probably existed during the last ice age, thus contradicting the favored H. Otley Beyer's theory that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouse Museums
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Ilocos Norte
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses In The Philippines
With the Philippine Archipelago comprising over 7,100 islands packed in an area of , the country has the fifth-longest coastline in the world. The Philippine coast has a total length of and is very irregular, with numerous bays, gulfs, and islets. Eleven of the largest islands of the archipelago are the major islands and main centers of population, with ten of its most populous cities located along the coast. Approximately 1,000 of the smaller islands are also populated. With more than of coasting routes and tortuous channels regularly navigated by vessels trading among some 300 separate ports, navigation aids like lighthouses help mariners against misnavigation and guide them to safety and out of danger from grounding on its treacherous reef and shoals. Large international ships rely on lighthouses to guide them safely out from the open sea and into Philippine waters. Once within Philippine waters, lighthouses help them maneuver through its narrow straits and channels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Photovoltaic Module
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation generates no pollution and no greenhouse gas emissions, it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required in PV system man ...

1990 Luzon Earthquake
The 1990 Luzon earthquake struck the island of Luzon in the Philippines at 4:26 p.m. on July 16 ( PDT) or 3:26 p.m. ( PST) with an estimated moment magnitude of 7.7 and a maximum Mercalli intensity of IX (''Violent'') and produced a 125 km-long ground rupture that stretched from Dingalan, Aurora to Kayapa, Nueva Vizcaya. The event was a result of strike-slip movements along the Philippine Fault and the Digdig Fault within the Philippine Fault System. The earthquake's epicenter was near the town of Rizal, Nueva Ecija, northeast of Cabanatuan City. An estimated 1,621 people were killed, most of the fatalities located in Central Luzon and the Cordillera region. Impact The earthquake caused damage within an area of about 20,000 square kilometers, stretching from the mountains of the Cordillera Administrative Region and through the Central Luzon region. The earthquake was strongly felt in Metropolitan Manila, destroying many buildings and leading to panic and sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressure Vessel For Cape Bojeador Light 2005
Pressure (symbol: ''p'' or ''P'') is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled ''gage'' pressure)The preferred spelling varies by country and even by industry. Further, both spellings are often used ''within'' a particular industry or country. Industries in British English-speaking countries typically use the "gauge" spelling. is the pressure relative to the ambient pressure. Various units are used to express pressure. Some of these derive from a unit of force divided by a unit of area; the SI unit of pressure, the pascal (Pa), for example, is one newton per square metre (N/m2); similarly, the pound-force per square inch (psi) is the traditional unit of pressure in the imperial and U.S. customary systems. Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as of this. Manometric units ...

Cupola
In architecture, a cupola () is a relatively small, most often dome-like, tall structure on top of a building. Often used to provide a lookout or to admit light and air, it usually crowns a larger roof or dome. The word derives, via Italian, from lower Latin ''cupula'' (classical Latin ''cupella''), (Latin ''cupa''), indicating a vault resembling an upside-down cup. Background The cupola evolved during the Renaissance from the older oculus. Being weatherproof, the cupola was better suited to the wetter climates of northern Europe. The chhatri, seen in Indian architecture, fits the definition of a cupola when it is used atop a larger structure. Cupolas often serve as a belfry, belvedere, or roof lantern above a main roof. In other cases they may crown a spire, tower, or turret. Barns often have cupolas for ventilation. Cupolas can also appear as small buildings in their own right.
