There is no definite protocol in management of small bowel obstruction in relation to duration and need of surgery. The aim is to study the role of gastrografin in management of small bowel obstruction.In this study patients who were diagnosed with intestinal obstruction were administered gastrografin. The patients were followed serially using x-ray at 4hrs interval for 24hrs; decision to operate was taken on non-progression of dye in two consecutive x-ray. Among 20 patients of this study 9 patients were operated on basis of gastrografin study. 11 were treated conservatively. 8 patients were of adhesive bowel obstruction. Out of which 1 was operated, 7 were treated conservatively. The sensitivity, specificity, positive and negative predictive value of gastrografin administration in this study was 100%, 89%, 92%, 100% respectively.Gas¬trografin helps in strengthening the clinical decision about the management of intestinal obstruction; it helps in early decision making regarding continuing the conservative or operative management and allows the introduction of oral intake earlier and earlier discharge from the hospital as well as reduction in operative rate.

Many authors have agreed to diagnostic methods that
include clinical findings, radiologic and laboratory outcomes. Early laparoscopic cholecystectomy is the best treatment for Grade
I and Grade II patients of the Tokyo Guideline 2018. For many
decades, the treatment protocol has been controversial for patients
presenting severe cholecystitis (Grade III AC) and those unfits for
surgery because of co morbidities. Recent authors advocated for
early laparoscopic cholecystectomy for Grade III patients. Delayed laparoscopic cholecystectomy is recommended for patients
who missed the golden 72 hours and presenting high risk of intra
operative complications. Cholecystostomy is described by many
scholars as alternative treatment for patients presenting comorbidities. Nowadays, Endoscopic trans papillary or transmural and

Applying Epidemiology
Epidemiology is the study of epidemics. More specifically, it is the study of the occurrence and distribution of health problems. Using any of the epidemiological techniques outlined in the chapters from this week’s reading, address the questions for one of the case studies outlined below.
· Epidemiological Case #1: Gastroenteritis at a University in Texas
· Epidemiological Case #2: Norovirus in Vermont
There are two parts to this assignment:
Part I: Provide a brief statement of the investigative issue. Describe the epidemiological steps you would take by addressing the questions asked within the case study you select.
Part II: Address the questions noted at the end of your selected case study. Your paper should be at least four pages in length, but can exceed this depending on how much detail you provide on the epidemiological steps you take for your case. You should use at least one additional scholarly source in addition to the textbook. Format your paper and all citations according to APA style guidelines as outlined in the Ashford Writing Center.
Carefully review the Grading Rubric for the criteria that will be used to evaluate your assignment.
Here is the Case Study that I chose
Epidemiological Case #1: Gastroenteritis at a University in Texas
PART I
On the morning of March 11, the Texas Department of Health (TDH) in Austin received a telephone call from a student at a university in south-central Texas. The student reported that he and his roommate, a fraternity brother, were suffering from nausea, vomiting, and diarrhea. Both had become ill during the night. The roommate had taken an over-the-counter medication with some relief of his symptoms. Neither the student nor his roommate had seen a physician or gone to the emergency room.
The students believed their illness was due to food they had eaten at a local pizzeria the previous night. They asked if they should attend classes and take a biology mid-term exam that was scheduled that afternoon.
Question 1: What questions (or types of questions) would you ask the student?
Question 2: Do you think this complaint should be investigated further?
TDH staff was skeptical of the student’s report but felt that a minimal amount of exploration was necessary. They began by making a few telephone calls to establish the facts and determine if other persons were similarly affected. The pizzeria, where the student and his roommate had eaten, was closed until 11:00 A.M. There was no answer at the University Student Health Center, so a message was left on its answering machine.
A call to the emergency room at a local hospital (Hospital A) revealed that 23 university students had been seen for acute gastroenteritis in the last 24 hours. In contrast, only three patients had been seen at the emergency room for similar symptoms from March 5-9, none of whom were associated with the university.
At 10:30 A.M., the physician from the University Student Health Center returned.

A concerned mother brings her 2-year-old daughter to the clinic with the complaint of fever,
irritability, and difficulty eating. Based upon what you have learned so far in class, what are
possible diagnoses and how would you differentiate between them?
Solution
In children the symptoms of epiglottitis include fever with chills difficulty swallowing refusing
to eat restlessness and irritability.
This disease can be diagnosed by observing X-rays and the wind pipe laryngoscopy.
The doctors day observed the swollen epiglottis by observing his throat.
Blood test also help observed infection ,other immunologic test also help for identifying the
antibodies to specific bacteria ore viruses.
Epiglottitis maybe misdiagnosed as strep throat. other misdiagnosis include infectious diseases
like diphtheria infectious mononucleosis, peritonsillar abscess.
An important misleading diagnosis is croup which occurs in younger children having viral
prodrome the children with croup has barking cough and rarely appears toxic they also it
experience sore throat, dyspnea and vomitings.
Epiglottis is very rare disease where as crop is very common epiglottis is caused by haemophilus
influenzae type b virus ,croup is caused by parainfluenza, rsv and enteror viruses ,epiglottis is
common in between the children 3 to 7 years where as crop is common between 3 months to 3
years. Fever is less in croup disease whereas fever > 39°c is observed in epiglottitis. Croup Is
benign where as epiglottitis is potentially critical.
Bacterial tracheitis may also mislead epiglottitis diagnosis..

Why is it important that chromosomes can cross over in Meiosis and not in Mitosis?
Solution
Crossing over results in genetic recombination. It is responsible for genetic diversity of the
population. Genetic recombination and natural selection are the driving force behind evolution.
Meiosis is called sex division, it is responsible for gamate formation. Crossing over occurs when
chiasma is formed and this random exchange of information leads to unique gametes formation
and genetic recombination to occur..

Solution
There are many critical roles of engineering in addressing the large-scale pressing challenges
being faced by the societies worldwide. Such large-scale major challenges include access to
affordable health care; tackling the coupled issues of energy, transportation and climate change;
providing more equitable access to information for our populations; clean drinking water; natural
and man-made disaster mitigation, environmental protection and natural resource management,
among legion others. In and of itself, mobilizing the engineering community to become more
efficient in delivering real products and services of benefit to society, especially in the
developing world, is a vitally important international responsibility. Engineering as a human
strive is also facing numerous additional challenges of its own, including attracting and holding
back broader cross-sections of our youth, particularly women; strengthening the educational
enterprise; forging more effective interdisciplinary alliances with the natural and social sciences
and the arts; enhancing our focus on innovation, entrepreneurship and job creation, and;
promoting increased public awareness and support for the engineering enterprise..

What is the role of RFID chips in logistics?
What is the role of RFID chips in logistics?
Solution
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and
track tags attached to objects. The tags contain electronically stored information. Passive tags
collect energy from a nearby RFID reader\'s interrogating radio waves. Active tags have a local
power source such as a battery and may operate at hundreds of meters from the RFID reader.
Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be
embedded in the tracked object. RFID is one method for Automatic Identification and Data
Capture (AIDC).[1]
The emergence of RFID (Radio Frequency Identification) technology has been greatly increased
efficiency in the production process management, material flow management, logistics and
transport, retail and distribution and other fields of the national economy industries, including
electronic information industry. RFID may eventually replace the ubiquitous bar code in the
future and become the main technology in logistics and supply chain management field
RFID in Logistics Management
Logistics management involves the efficient control of some or all of the supply chain functions,
including:
– Product research and development
– Sourcing and purchasing
– Manufacturing
– Production planning
– Sales, marketing, and forecasting
– Inventory management
– Cross-docking and flow-through
– Customer service
– Transportation
– Freight payment
– Information reporting
Using RFID logistics tracking has helped many organizations solve the main challenge at every
node in their supply chains: the lack of visibility of logistics data. RFID technology is a powerful
solution that improves asset visibility, data quality, inventory management, and interoperability
in an end-to-end integrated supply chain. In fact, the U.S. Department of Defense (DoD) issued a
mandate in 2005 that requires all of their suppliers to use RFID in marking any items that are
sold to the DoD. The need for this mandate arose from decades of logistical challenges faced by
the military with regard to the supply chain.
RFID has proven to alleviate various logistical problems associated with the DoD supply chain.
RFID technology, in combination with the Internet, allows the DoD to disseminate accurate,
real-time data to commanders worldwide so that assets can be easily located and used according
to the Department’s highest priorities..

eukaryotic cells is the mitochondria, which generates the chemical energy for the cell. In contrast
the chloroplast is a type of organelle found only in the cells of plants and algae and performs

Community policing is a philosophy that promotes organizational strategies, which support the
systematic use of partnerships and problem-solving techniques, to proactively address the
immediate conditions that give rise to public safety issues such as crime, social disorder, and fear
of crime.
Community policing is a philosophy of full service personalized policing, where the same officer
patrols and works in the same area on a permanent basis, from a decentralized place, working in
a proactive partnership with citizens to identify and solve problems.
Positive effects of Community policing :
Prevent crime
Address /Reduce fear of crime
Elicit the citizen development
Creative problem solving
Create active cooperation with Employee & Resident
Negative effect of community pricing :
The effects to examine is liability lawsuits
Risk taking leads to more litigation\'s and community-oriented policing involves risk taking due
to the modern management that is involved in community oriented policing
Nature & Extent of civil liability
Community pricing is dependent on community .Each community is different.
Primary focus of community policing:
The main focus of community policing is to solve the problems of society.For police
departments its not possible to control each & every thing , so they take some help from society .
The problems where arises these teams are helping to solve the problems.

List and describe three examples of secondary sexual characteristics.pdfarihantcommunication
List and describe three examples of secondary sexual characteristics each for males and females.
Solution
Secondary sex characteristics are features that appear at sexual maturity in animals and during
puberty in humans, Secondary sex characteristics are Traits that distinguish the biological sexes
of a species, but are not directly part of the reproductive system.
Examples of secondary sex characteristics in humans include shorter stature and wider pelvis,
breast development, and more fat in the thighs and buttocks in women and broader shoulders,
greater muscle mass, more facial and other body hair, and “male pattern” baldness in men.
Male secondary sexual characteristics of hair:
The pubic regions is usually the first to develop hair
Facial hair begins at the corner of the mouth and spreads to the midline - followed by the rest of
the face
Body hair develops long before facial hair growth is complete (arm pit, legs, arms, buttocks,
back)
Male secondary sexual characteristics of vocal changes:
Rapid growth of the larynx - larger and stronger
The thyroid cartilage increases in dimension creating the Adam\'s apple
Vocal cords lengthen and thicken.
Male secondary sexual characteristics of the body:
Increase in body size, weight and strength (musculature)
Correlated to increase in testosterone levels
Female secondary sexual characteristics of hair:
The pubic regions is usually the first to develop hair
Body hair develops slightly later (arm pit, legs, arms)
female secondary sexual characteristics of the pelvis:
Broadens and changes from a narrow funnel-like outlet, to a broad oval outlet, flaring at the hip
Fat cells increase in number around the buttocks and thighs
Female secondary sexual characteristics of the breasts:
Tanner Stages
Tanner I
no glandular tissue, typically age 10 and younger
Tanner II
Breast bud forms, with small area of surrounding glandular tissue, 10-11.5
Tanner III
breast begins to become more elevated, and extends beyond the borders of the areola, 11.5-13
Tanner IV
increased breast size and elevation, 13-15
Tanner V
breast reaches final adult size, 15+.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
