Luis T. Hernandez Terrazas. Luis Trinidad Hernandez Terrazas (born c. 1906 in Chihuahua, Mexico; death date unknown) was a Mexican engineer who founded the brand LTH, one of the leading car battery brands in Mexico.

Biography 
Luis T. Hernandez Terrazas was born in Mesa de Cristo Rey, Chihuahua, Mexico in 1906 where he studied electricity by correspondence, initially working on improving the engine starting crank system. He converted his mechanic shop to a place he can work on his ideas, where he invented a battery to maintain its charge for a long time. He noticed the method of cranking an engine was coming to an end, so he devised a black box as an accumulator to store energy. At age 20, he moved to Monterrey, Nuevo Leon, Mexico to bring his idea to the land of automotives where he believed there would be numerous cars in the city.

He established the brand LTH, in 1928, using his initials as it is shown on the front of the battery, for Mexico that was recovering from the revolution. In order to make sure his ideas were successful; he had conducted multiple tests to prove his batteries were effective for the public, where he succeeded. He established his shop a few blocks from the Palacio de Gobierno in Monterrey at the corner of the streets Aramberri and Zaragoza. He sold his company to the American company Johnson Controls. As of today, LTH is one of the leading car battery brands in Mexico and Latin America for over 90 years.

1987 Bakhtar Afghan Airlines Antonov An-26 shootdown. The 1987 Bakhtar Afghan Airlines Antonov An-26 shootdown was a military incident that occurred on June 11, 1987, during the Soviet–Afghan War. A Bakhtar Afghan Airlines Antonov An-26 was shot down by a missile near Khost, Afghanistan, resulting in 53 fatalities out of the 55 people on board. Afghan mujahideen insurgents fired the missile that struck the Bakhtar Afghan Airlines Antonov An-26. These insurgents were using surface-to-air missiles supplied by international supporters, including the United States as part of their efforts to combat Soviet and Afghan government forces during the Soviet–Afghan War.

Background 
Bakhtar Afghan Airlines, the national carrier of Afghanistan, operated domestic flights across the country, often over conflict zones. The Antonov An-26 involved in this incident, registered as YA-BAL, was manufactured in 1985 and was actively used for domestic flights within Afghanistan.

Aircraft details 
The Antonov An-26 is a twin-engined turboprop civilian and military transport aircraft, known for its robustness and versatility. It can carry up to 40 passengers or 5,500 kg of cargo and features a rear ramp door for quick loading and unloading. The aircraft involved, registered as YA-BAL, had the manufacturer's serial number 14105.

Incident 
On June 11, 1987, the Antonov An-26 departed from Kandahar, carrying 55 people, including both passengers and crew members. The flight was part of Bakhtar Afghan Airlines' routine operations. Shortly after takeoff, as the aircraft was flying near Khost, it was targeted and struck by a surface-to-air missile. The missile caused catastrophic damage, leading to the aircraft crashing. The attack resulted in 53 fatalities, with only two survivors. 

The attack was part of the ongoing conflict during the Soviet–Afghan War, where insurgent groups frequently targeted aircraft, mistaking them for military transports. In this case, it was believed that the rebels thought the Antonov An-26 was a military Ilyushin Il-14.

Methoxyacrylates. Methoxyacrylates (more precisely β-methoxyacrylates) are a group of organic compounds primarily used as fungicides. They comprise an acrylic acid ester unit that also includes a methoxy group, making them a type of enol ether.

Structure and effect 
The methoxyacrylate group is derived from strobilurins. Strobilurins feature a diene unit, which renders them only slightly photostable. In their synthetic analogs, this diene unit is typically replaced by other structural elements, usually aromatic rings. Methoxyacrylates inhibit cytochrome c oxidase, thereby blocking electron transport and the respiratory chain in the mitochondrion of fungi. Specifically, the active ingredients bind to the binding site for the oxidation of ubiquinol. The interruption of the respiratory chain prevents the biosynthesis of adenosine triphosphate, leads to energy deficiency and thus to the death of the fungi. The methoxyacrylate unit is critical to this inhibitory effect, which is why the active substance group is named after it.

Representatives and use 

Notable representatives of methoxyacrylates include azoxystrobin and picoxystrobin. Broadly speaking, the term also encompasses compounds lacking a methoxyacrylate unit, such as kresoxim-methyl, which features an oxime ether unit instead. This unit is isosteric with the enol ether unit, allowing the compound to exert a similar effect. Azoxystrobin was the first compound of this group to be approved in 1996, and more than ten compounds are now in commercial use. Additional representatives include pyraclostrobin, trifloxystrobin, fluoxastrobin, enoxastrobin, metominostrobin, coumoxystrobin, dimoxystrobin, fluacrypyrim, and orysastrobin.

Methoxyacrylates are utilized as agricultural fungicides. Their primary advantage is their potent toxicity against a wide range of fungi, coupled with low toxicity in mammals, making them a vital class of active ingredients. Methoxyacrylates hold significant importance in the field of agricultural fungicides, with a substantial market share. In 1999, this group of active ingredients accounted for over 10% of the fungicide market, with sales totaling US$620 million, led by azoxystrobin, which alone generated approximately US$415 million in sales. In 2016, methoxyacrylates continued to dominate the fungicide market, with the top three fungicides by sales value—azoxystrobin, pyraclostrobin, and trifloxystrobin—all belonging to this group.
