Michael Kramer's O - Ring Theory is about sequential production. A firm can produce great quality products but if its marketing is messy, it can make a loss. I apply the idea of the O - Ring to explain what happens in the agriculture sector in Malawi
We have a subsidy program in Malawi which is good but with little going to extension services and R&D, the subsidy is not having much of an impact.
I also explore other factors which affect overall agriculture production
All such factors inputed into the O - Ring Production Function of say maize, have an effect on output
Screening and Production of Protease Enzyme from Marine Microorganism and Its...iosrjce
Marine sediment samples were collected from the Gulf of Mannar, Mandapam coast to screen for
protease producing microbes. Among the five isolates screened only two isolates showed maximum proteolytic
activity with the zone of 21mm and 19mm respectively. Biochemical characterization of the isolates were
performed and identified as strain P2 belonged to Bacillus subtilis and strain P5 belonged to Bacillus
licheniformis. Both the strains have the ability to tolerate 7%Nacl concentration. The amount of protease
produced was expressed in microgram of tyrosine released under standard assay conditions. The total protein
content of crude enzyme extracts of Bacillus subtilis and Bacillus licheniformis were quantified which revealed
21.2mg/ml for strain P2 and 22.4mg/ml of protein content was presented by strain P5. The proteolytic bacteria
gave an optimum performance were both strains exhibited the enzymes stable at PH
7. In the present study
Bacillus subtilis showed a remarkable activity at 40ºC where as Bacillus licheniformis exhibited maximum
activity at 50ºC. Studies pertaining to carbon sources starch and lactose were utilized by Bacillus subtilis and
Bacillus licheniformis and maximum production was achieved. Among the different nitrogen sources tested
yeast extract induced maximum proteolytic activity where as ammonium sulphate was found to be the best
nitrogen sources for protease production. The crude enzyme was efficient to remove hair dye and blood stain by
Bacillus subtilis and Bacillus licheniformis
The drugs which are obtained from marine organisms are know as marine drugs. these marine drugs are used since ancient times. chines and japanes are very famous to use these resources. And interstingly,innumarable products derived from the marine organisms in several 'crude forms' have been widely used across the globe by the traditional practitioners for thousands of years.

Broodstock And Hatchery Management Of Penaeus Monodonsush_p
Shrimp aquaculture is an important and valuable production sector that has been growing rapidly over the past two decades. Success is largely based on the quality of post larvae, particularly their health condition, thus making hatchery production of quality post larvae crucial to the sector’s sustainability. Vietnam is the leading producer of black tiger shrimp in the world with a production of 300,000 tons in 2011, followed by India and Indonesia with a production of 187,900 tons and 126,200 tons respectively.
Major contribution of the tiger shrimp to global shrimp production and the economic losses resulting from disease outbreaks, it is essential that the shrimp-farming sector invest in good management practices for the production of healthy and quality seed. The Indian shrimp hatchery industry has established a detailed guidance and protocols for improving the productivity, health management, biosecurity and sustainability of the sector. Following a brief review of shrimp hatchery development in India, the major requirements for hatchery production are discussed under the headings: infrastructure, facility maintenance, inlet water quality and treatment, wastewater treatment, biosecurity, standard operating procedures (SOPS), the Hazard Analysis Critical Control Point (HACCP) approach, chemical use during the hatchery production process and health assessment. Pre-spawning procedures include the use of wild, domesticated and specific pathogen free/ specific pathogen resistant (SPF/SPR) broodstock, broodstock selection and holding techniques, transport, utilization, health screening, maturation, nutrition and spawning, egg hatching; nauplius selection, egg/ nauplius disinfection and washing and holding, disease testing and transportation of nauplii. Post-spawning procedures include: larval-rearing unit preparation, larval rearing/health management, larval nutrition and feed management, important larval diseases, quality testing/selection of PL for stocking, PL harvest and transportation, nursery rearing and record keeping.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Immunization with a circular piece
of DNA that code for an antigen
Plasmids consist of strong viral
promoter to drive the in vivo
transcription and translation
When injected into an individual,
the plasmid is taken up by the host
cells and its genetic information is
translated into the immunizing
protein.
Multicistronic vectors are
sometimes constructed to express
more than one immunogen, or to
express an immunogen and an
immunostimulatory protein.

83. Production of Yolk antibodyProduction of Yolk antibody
Principle
When chickens are faced with a foreign virus or
bacterium, they produce antibodies to fight the
invader. They pass that immunity on to their
offspring, and antibodies wind up in the eggs.
1. Chickens are more apt than mammals to make
high-avidity antibodies
2. A single chicken can produce an enormous
amount of antibody, upto 3 grams of IgY per
month, which is 10-20 times the amount of a
rabbit
3. chickens produce antibody much quicker-
high-titre antibody is available from eggs as
early as day 25
4. Storing of eggs (antibodies) is very easy
5. It is cheaper to feed and house chickens than
rabbits
6. Effective against drug-resistant bacteria.

Algal BioplasticsAlgal Bioplastics
TTypically, long chain polymers, present in the
algae lipids are used for making bioplastics
Algae is attractive for bioplastics because of
its high growth rate and high protein content.
The plastics market is worth more than $400
billion and has grown at an average of 3.5% per
year over the last two decades.
94. Algal Biogas ProductionAlgal Biogas Production
In a biogas reactor the substrates used are converted in several reaction
steps into biogas, consisting mainly of the components CH4 and CO2
The biogas yield of plants is generally limited by the greater or lesser
proportion of lignocellulose, which is difficult to recycle.
However, the use of microalgae with a low lignocellulose content, for
example Chlorella vulgaris, Phaeodactylum tricornutum and Spirulina
platensis, permits an almost complete utilization of the organic substance.

110. Scope of PlanktonologyScope of Planktonology
The students more practically in the job
rendering areas in planktons including algal
oil production, carotenoid industries, and
aquaculture sections, the students who
complete this Diploma will get job
opportunities in National and Global
employments
The syllabi framed for this course has made
only after consultation with the foresaid
plankton based industries and also the
students will be trained in plankton based
industries to complete their project work.
After analyzing all the renewable oil
resources, the microalgae which has more
than 50% of lipid to its body weight has now
been identified as an alternative to solve the
future fuel scarcity
