Business and organizations

TCBY

TCBY, originally standing for "This Can't Be Yogurt," is an American frozen yogurt franchise founded in 1981 by Frank Hickingbotham in Little Rock, Arkansas, and is credited with opening the first frozen yogurt shop in the United States.^[1]^[2] The chain pioneered the soft-serve frozen yogurt concept, initially emphasizing low-fat and non-fat varieties as a healthier alternative to traditional ice cream, which helped popularize the treat during the health-conscious 1980s.^[3]^[4] The franchise expanded rapidly through franchising, reaching a peak of approximately 3,000 locations worldwide in the early 1990s across more than 70 countries.^[5] By the early 2000s, however, competition from self-serve yogurt shops and shifting consumer trends led to a decline, with the company filing for bankruptcy in 2008.^[6] In 2000, TCBY was acquired by Mrs. Fields Famous Brands for $140 million, integrating it into a portfolio that included cookie outlets and leading to co-branded locations.^[7]^[8] Following restructuring in 2011 under creditors including Z Capital Partners, and a full acquisition by Z Capital in 2013, the parent company Famous Brands International was bought by Pearl Street Equity in 2023.^[6]^[9]^[10] As of 2025, TCBY operates approximately 140 locations in the United States and about 25 internationally, focusing on soft-serve frozen yogurt in flavors like vanilla and chocolate, customizable with over 70 toppings such as fruits, candies, and nuts.^[11] The menu continues to highlight low-fat and dairy-free options, including Greek yogurt varieties introduced in 2012, maintaining its reputation for nutritional appeal without compromising taste.^[12]^[4]

Computing

Trusted computing base

The Trusted Computing Base (TCB) is defined as the totality of protection mechanisms within a computer system, including hardware, firmware, and software components, that are responsible for enforcing a security policy.^[13] This encompasses all elements critical to the system's security, such as the kernel, access control mechanisms, and cryptographic modules, which collectively ensure isolation of sensitive processes and data from unauthorized access.^[14] The concept originated in the 1980s as part of the U.S. Department of Defense's efforts to standardize secure computer systems, formalized in the Trusted Computer System Evaluation Criteria (TCSEC), commonly known as the Orange Book, published in 1985.^[14] This document established evaluation classes for trusted systems, emphasizing the TCB's role in multilevel security environments handling classified information, building on earlier research from the 1970s like the Anderson Report on reference monitors.^[14] Key properties of the TCB include verifiability through formal methods and testing to confirm correct enforcement of security policies, tamper-resistance to prevent unauthorized modifications, and isolation from untrusted system components via techniques like process separation and address space protection.^[14] A foundational principle is the reduction of the TCB's size and complexity, achieved by excluding non-security-critical elements and applying system engineering practices, which enhances reliability and minimizes potential vulnerabilities.^[14] In modern systems, the TCB is exemplified by Security-Enhanced Linux (SELinux), where mandatory access controls and policy enforcement limit privileges to protect the kernel and critical services from compromise.^[15] Similarly, Trusted Platform Module (TPM) chips form part of the hardware TCB, enabling secure boot processes that cryptographically verify firmware and bootloader integrity before execution, ensuring only trusted code runs on the system.^[16] Unlike task control blocks, which manage process scheduling in operating systems, the TCB focuses on overarching security architecture.^[14]

Task control block

The Task Control Block (TCB) is a kernel-level data structure in operating systems, particularly real-time operating systems (RTOS), that stores essential state information for a task or process to enable efficient management and execution. It typically includes fields such as the program counter, stack pointer, CPU registers (including floating-point registers), process identifier, priority level, current state (e.g., ready, running, blocked, or suspended), memory allocation pointers, and resource usage details like I/O status or semaphore ownership.^[17]^[18]^[19] TCBs are commonly employed in RTOS such as VxWorks and other embedded systems to handle multitasking in resource-constrained environments, where tasks require deterministic behavior and quick response times. In these systems, the TCB maintains fields for task priority to support preemptive scheduling, execution status for queue management, and pointers to allocated resources like stacks or message queues, facilitating coordination among concurrent tasks without excessive overhead.^[20]^[21]^[19] A TCB is allocated and initialized by the kernel during task creation, which involves reserving memory for the task's stack and populating the TCB with initial values like the entry point address and default priority. Throughout the task's lifecycle, the TCB is updated during context switches—saving the current task's registers and program counter to its TCB and loading the next task's from its own—ensuring seamless transitions in multitasking scenarios. Upon task termination, the TCB is deallocated, releasing associated resources back to the system.^[22]^[21]^[23] The TCB plays a critical role in enabling multitasking by providing the operating system scheduler with a compact, accessible snapshot of each task's context, allowing rapid save-and-restore operations that minimize latency in real-time applications. This structure supports efficient resource allocation and state tracking, essential for systems where tasks must meet strict timing deadlines. In secure environments, TCBs can integrate briefly with broader trusted computing mechanisms to isolate task contexts, though their primary function remains process management.^[23]^[24]^[25]

Trouble came back

In computing, particularly within IBM's engineering culture, TCB stands for "Trouble Came Back," a term coined to describe intermittent software bugs that seemingly resolve themselves but return unpredictably, defying neglect or hasty fixes.^[26] This slang emerged from maintenance teams dealing with elusive issues in early computing systems, where problems would vanish under observation only to reappear later.^[27] Such TCB bugs are characteristically non-reproducible, making them resistant to conventional debugging methods like code reviews or isolated testing, and they often arise from subtle causes including race conditions in concurrent code or variations in environmental factors such as timing, memory states, or hardware fluctuations.^[26] For instance, a race condition might trigger the failure sporadically depending on thread scheduling, while environmental triggers like temperature changes could affect hardware-related intermittents.^[28] The term gained wider recognition in hacker and developer communities through its inclusion in the Jargon File, a longstanding compendium of technical slang, where it is distinguished from "one-shot" bugs that occur only once and from heisenbugs that alter behavior when probed.^[26] This entry helped embed TCB in broader software folklore, emphasizing the frustration of persistent yet elusive defects.

Music

TCB Band

The TCB Band was established in August 1969 as the rhythm section for Elvis Presley's comeback performances in Las Vegas, organized by lead guitarist James Burton at Presley's request. The initial lineup included Burton on lead guitar, John Wilkinson on rhythm guitar, Larry Muhoberac on keyboards, Jerry Scheff on bass, and Ronnie Tutt on drums. In 1970, Glen D. Hardin replaced Muhoberac on keyboards, forming the core group that remained stable through most of the band's tenure.^[29] The band provided essential instrumentation for Presley's live concerts and studio recordings from 1969 to 1976, supporting his transition to a high-energy stage presence with a tight, professional sound. They accompanied Presley on extensive tours across the United States, performing hundreds of shows that revitalized his career and drew massive audiences. Their contributions extended to key recordings, including sessions for 1970s albums such as Elvis Country (I'm 10,000 Years Old) and live releases capturing the era's performances.^[30]^[31] The TCB Band's legacy endures through their pivotal role in Presley's 1970s resurgence, notably featured in the documentary film Elvis: That's the Way It Is, which documented rehearsals and Las Vegas shows. The group disbanded following Presley's death on August 16, 1977. The band's name derived from Presley's personal motto "Taking Care of Business," symbolized by a lightning bolt necklace he designed in 1970 for himself and close associates, representing efficiency and dedication.^[32]^[31]

TCB (album)

TCB is a studio album by Australian rock musician James Reyne, released in April 2010 by Liberation Music.^[33] The album consists entirely of cover versions of songs originally popularized by Elvis Presley, serving as a tribute to the rock 'n' roll icon whom Reyne has cited as a major influence. The title TCB stands for "Taking Care of Business," a phrase associated with Presley's inner circle and his backup group, the TCB Band, reflecting the album's thematic nod to Presley's legacy.^[34] Produced by Charles Fisher, known for his work on pop records like those by Savage Garden, the album features a clean, contemporary rock production that updates the originals with a sharper, digital sound while preserving their energetic spirit.^[34] Reyne's interpretations emphasize his matured vocal style, avoiding direct imitation of Presley and instead infusing the tracks with his own rock sensibilities honed from decades in the industry. Highlights from the 14-track album include renditions of "Viva Las Vegas," "Burning Love," and "All Shook Up," which showcase Reyne's gravelly delivery and the band's tight instrumentation.^[35] Upon release, TCB debuted and peaked at number 32 on the ARIA Albums Chart, marking moderate commercial success in Australia and appealing to fans of both Reyne and Presley.^[33] Critics praised the album's respectful yet fresh take on the Presley catalog, noting Reyne's confident handling of the material after 30 years of performing.^[34] The project underscored Reyne's versatility, blending tribute with personal artistry in a concise collection that honors the King's enduring impact on rock music.

Science and technology

1,2,4-Trichlorobenzene

1,2,4-Trichlorobenzene is a chlorinated aromatic compound with the chemical formula C₆H₃Cl₃ and a molecular weight of 181.46 g/mol.^[36] It appears as a colorless liquid at room temperature, with a boiling point of 214 °C and a density of 1.45 g/cm³ at 25 °C.^[37] The compound is sparingly soluble in water but soluble in organic solvents, exhibiting a log K₀w of 4.02, which indicates potential for bioaccumulation in the environment.^[36] This substance is produced through the chlorination of benzene, where benzene is reacted with chlorine gas under controlled conditions to yield a mixture of trichlorobenzene isomers, with 1,2,4-trichlorobenzene being the predominant product.^[38] Global production capacities for 1,2,4-trichlorobenzene are in the range of tens of thousands of tons annually, as exemplified by major producers like Jiangsu Huaijiang Technology with a capacity of 30,000 tons.^[39] Due to its persistence in the environment and toxicity, production has been limited in many regions under regulatory scrutiny. 1,2,4-Trichlorobenzene has been used as a dye carrier, an intermediate in herbicide synthesis, a heat-transfer medium, a dielectric fluid in transformers, a degreaser, and a lubricant.^[40] It was formerly employed as an insecticide for termite control but has been phased out from such applications due to health and environmental concerns.^[36] The compound is toxic upon oral or inhalation exposure, causing liver and adrenal effects in animal studies, and the U.S. Environmental Protection Agency (EPA) has classified it as Group D—not classifiable as to human carcinogenicity—while designating it a hazardous air pollutant under the Clean Air Act.^[41]^[42] In response to these risks, efforts in green chemistry are focused on developing safer alternatives for its solvent and intermediate roles to minimize persistent organic pollutant releases.^[43] As a trisubstituted benzene derivative, 1,2,4-trichlorobenzene differs from more highly chlorinated analogs like tetrachlorobenzene by having one fewer chlorine atom, influencing its reactivity and applications.^[40]

Tetrachlorobenzene

Tetrachlorobenzenes are a group of three isomeric chlorinated aromatic hydrocarbons with the molecular formula C₆H₂Cl₄, consisting of 1,2,3,4-tetrachlorobenzene, 1,2,3,5-tetrachlorobenzene, and 1,2,4,5-tetrachlorobenzene. The 1,2,4,5-isomer is the most prevalent in environmental contexts due to its historical production and persistence. These compounds are structurally similar to trichlorobenzene isomers, featuring an additional chlorine substitution on the benzene ring. Historically, tetrachlorobenzenes, particularly the 1,2,4,5-isomer, were used as components in dielectric fluids combined with polychlorinated biphenyls (PCBs) for electrical transformers and capacitors, as well as in dyestuff carriers and chemical synthesis intermediates for pesticides. Production and use have significantly declined since the late 20th century due to health and environmental concerns associated with PCBs and chlorinated aromatics. In Canada, imports are now limited to less than 0.1 kg annually for laboratory purposes.^[44]^[45] The 1,2,4,5-tetrachlorobenzene is a white crystalline solid at room temperature with a high melting point of 138–140 °C, low water solubility (2.16 mg/L at 25 °C), and a log Kₒw of 4.86, indicating strong partitioning into organic phases. It has low volatility (vapor pressure 0.005 mmHg at 25 °C) but can undergo long-range atmospheric transport as a volatile organic compound. These properties contribute to its persistence in sediments and soils under anaerobic conditions, where degradation is slow.^[46]^[47] Tetrachlorobenzenes exhibit bioaccumulative potential, with bioconcentration factors exceeding 10,000 in fish such as rainbow trout, leading to magnification in aquatic food chains. They are highly toxic to aquatic organisms, with acute LC₅₀ values for fish around 0.3–1.2 mg/L and chronic no-observed-effect concentrations below 0.0065 mg/L, causing effects like reduced reproduction and growth in invertebrates. Environmental releases occur primarily from legacy industrial sites, dielectric fluid spills, and as impurities or degradation products of higher-chlorinated benzenes like pentachlorobenzene and hexachlorobenzene. Detection in global sediments, such as the Great Lakes (up to 7,000 ng/g dry weight), air (0.2 ng/m³), and water (up to 146 ng/L) underscores their widespread contamination.^[44]^[46] Remediation of tetrachlorobenzene-contaminated sites focuses on techniques exploiting microbial dechlorination under anaerobic conditions. Bacterial strains, such as Pseudomonas sp. and anaerobic consortia, can reductively dechlorinate 1,2,4,5-tetrachlorobenzene to less chlorinated intermediates like 1,2,4-trichlorobenzene, with degradation rates enhanced by electron donors like lactate or hydrogen. Bioremediation has been demonstrated in sediments and groundwater, achieving up to 90% removal in lab-scale studies, though field applications require monitoring for incomplete dechlorination products. Photodegradation in surface waters also contributes to natural attenuation.^[48] As of 2025, production of tetrachlorobenzenes remains highly restricted globally, with the 1,2,4,5-isomer classified as "toxic" under Canada's Environmental Protection Act (Schedule 1, CEPA 1999) and subject to virtual elimination measures. In the European Union, it is registered under REACH with hazard classifications for acute aquatic toxicity (Category 1) and chronic aquatic toxicity (Category 1), limiting its use in Annex XIV authorizations and prohibiting concentrations above 0.1% in consumer articles under restricted substances lists. Legacy contamination sites, particularly near former electrical equipment facilities, are monitored internationally through frameworks like the Great Lakes Water Quality Agreement, with ongoing efforts to mitigate releases and human exposure via fish consumption advisories.^[45]^[49]^[44]

Thermal circuit breaker

A thermal circuit breaker (TCB) is an electrical safety device designed to protect circuits by automatically interrupting current flow when excessive heat from overloads causes the internal temperature to exceed a safe threshold. This protection mechanism relies primarily on a bimetallic strip, composed of two dissimilar metals bonded together with different coefficients of thermal expansion; when heated by sustained overcurrent, the strip bends, actuating a switch to open the circuit and halt the flow. Some TCB designs incorporate thermal fuses, which melt at a specific temperature to permanently break the connection, providing a non-resettable safeguard.^[50]^[51]^[52] In terms of design, TCBs are compact and mechanically simple, lacking electronic components, which makes them reliable in harsh environments. They are commonly deployed in household appliances like ovens and air conditioners for overload protection, as well as in automotive applications such as starter motors and lighting systems in vehicles. Resettable variants include automatic reset models that restore function after cooling (suitable for intermittent loads like fans), manual reset types for critical equipment requiring operator intervention, and modified reset designs that demand power disconnection before reactivation; in contrast, one-time thermal fuses offer cost-effective but non-reusable protection for low-risk circuits.^[50]^[53] TCBs adhere to established international standards to ensure performance and safety, including UL 489 in the United States for molded-case circuit breakers used in branch-circuit protection and UL 1077 for supplementary protectors within equipment enclosures. Globally, IEC 60898-1 governs low-voltage circuit breakers, specifying requirements for thermal-magnetic operation. Their response time is governed by the gradual heat accumulation from overload currents, resulting in trip curves where moderate overloads (e.g., 135% of rated current) may take minutes to trip, while higher levels accelerate the process to seconds, prioritizing protection against sustained thermal damage over instantaneous faults.^[54]^[55]^[56] As of 2025, TCB technology is advancing through integration with smart grids and Internet of Things (IoT) frameworks, particularly in home automation systems where embedded sensors enable remote monitoring of thermal conditions and predictive alerts for potential overloads. This evolution supports energy-efficient applications, such as IoT-enabled circuit breakers in residential panels that combine traditional thermal protection with wireless diagnostics to optimize grid stability and reduce downtime.^[57]^[58]

Other uses

Taking care of business

"TCB" is an abbreviation for the idiom "taking care of business," which refers to efficiently handling one's responsibilities or duties.^[59] This phrase emerged as common American slang in the mid-20th century, gaining widespread popularity during the 1960s and 1970s as a motivational expression for productivity and getting things done.^[60] Elvis Presley adopted "Taking Care of Business" as his personal motto in 1969 upon returning to live performances, using it to describe his approach to professional commitments.^[31] He symbolized the phrase with a logo featuring the letters "TCB" alongside a lightning bolt, representing "taking care of business in a flash," designed by his then-wife Priscilla Presley.^[61] Presley frequently gifted TCB necklaces and rings emblazoned with this emblem to his close friends, family, and entourage, including the women in his inner circle known as the "Memphis Mafia" and his backing musicians, the TCB Band.^[62]^[63] The phrase spread through music and popular culture, notably in Bachman-Turner Overdrive's 1973 hit song "Takin' Care of Business," which celebrated the routine of commuting to work and fulfilling daily obligations, further embedding the idiom in rock music and everyday language.^[64]^[65] It has since permeated business, motivational speaking, and self-help contexts as a shorthand for decisive action.^[66] As of 2025, "TCB" remains prevalent in corporate jargon to denote focused productivity and task completion, often appearing in professional emails, team mottos, and social media memes promoting work ethic and efficiency.^[66]

Treinta y Tres Airport

Treinta y Tres Airport is a small regional facility located near the city of Treinta y Tres, the capital of Treinta y Tres Department in eastern Uruguay. The airport serves the surrounding area, which is characterized by agricultural and pastoral landscapes, and facilitates regional flights for local connectivity. Positioned approximately 5 kilometers northeast of the city center, it supports access to this sparsely populated interior region of the country.^[67]^[68] The airport features a grass-surfaced runway measuring 1,070 meters (3,510 feet) in length, suitable for light aircraft operations. It primarily handles general aviation activities, including private flights, flight training, and occasional charter services, with no scheduled commercial passenger routes as of 2025. Its ICAO code is SUTR, and it lacks advanced infrastructure such as paved runways or terminal buildings, limiting its capacity to smaller propeller-driven planes. Operations are influenced by the airport's elevation of 62 meters (203 feet) above sea level and its location in a relatively flat, rural terrain.^[69]^[67] Established in the mid-20th century to provide basic air access to the department, the airport has seen limited expansion and commercial utilization over the decades. Its role remains modest due to the proximity of major hubs like Montevideo's Carrasco International Airport, approximately 250 kilometers to the southwest, which handles most national and international traffic. As a result, Treinta y Tres Airport focuses on non-scheduled flights rather than regular airline services.^[68]^[69] The facility plays a key role in supporting the local economy, particularly agriculture—dominated by cattle, sheep rearing, and crops such as wheat, corn, oats, and linseed—and emerging tourism initiatives in the region. General aviation flights aid in transporting agricultural personnel, equipment, and produce, while occasional charters enhance access for visitors exploring natural sites, historical landmarks, and rural experiences in Treinta y Tres Department. This contributes to the area's development without relying on larger transport networks.^[68]
