Mourinho admits misfiring Manchester United 'need some time'
Socceruncle | Aug. 27, 






The Portuguese has been under scrutiny following a 3-2 defeat to Brighton, but believes he is still making up for a testing pre-season
Manchester United manager Jose Mourinho has stressed his side "need some time" to get up to speed in the new Premier League season.
United were beaten 3-2 by Brighton in their second game of the campaign and they face Tottenham on Monday already six points behind the likes of Liverpool and Chelsea, albeit with a game in hand.
Rumours of discontent behind the scenes at Old Trafford have been swirling and Mourinho's terse press conference last week did little to dispel the notion all is not well.
In terms of United's on-field fortunes, Mourinho has welcomed the Spurs fixture coming eight days after the Brighton contest as he feels his players entered the new campaign without sufficient preparation.
"When you have a good week, when you train really well, things are positive, you expect good individual performances," he told Sky Sports.
"You don't expect mistakes and you expect a good result, not a defeat.
"Normally when you lose you want to play immediately and two days after that was not the case. But I am happy that was not the case because in this moment we need some time.
"We need players to be back, we need players to train more, to have a kind of pre-season after the pre-season that they didn't have after the World Cup."
Mourinho is hoping to see his side raise their game against Spurs, with United holding fond memories of recent meetings with the north London outfit.
The Red Devils edged out Mauricio Pochettino’s team in last season’s FA Cup semi-finals, with three points now being sought on a Premier League stage.
"It is a big game against a good opponent, an opponent that last season, in all the three matches we played, they were difficult matches in spite of [the fact] we won two of them,” said Mourinho.
"It [the FA Cup semi-final] was a good performance, away from home where everybody was expecting us to lose the match. We didn't start well and conceded an early goal and after that we had the quality and the mentality to change the result, to be dominant in the second half and it was a really good performance.
"We know what a good team they are and we know that they come here with their objectives. Big match but no need to work much on the motivational level because we have natural motivation to play against the good teams."

37 corps members escape death in Ogun accident
Global News NG | Aug. 14, 2018




Thirty-seven members of the National Youth Service Corps, (NYSC,) who completed their service on Monday in Ogun State, were involved in an accident shortly after leaving the orientation camp in Sagamu.
The Sector Commander of the Federal Road Safety Commission, (FRSC), Ogun State Command, Clement Oladele, who confirmed this, said 19 of them comprising nine males and ten males were injured.
He said the corps members were heading to Sango en route Ibadan-Lagos Expressway in a white coloured coaster bus, when the accident occurred around the Danco petrol station axis. He said none of them died, but some sustained ”serious injuries”.
Mr Oladele said the accident was caused by speed violation and loss of control by the driver. He also said the injured victims were evacuated to FRSC Accident Emergency Clinic at Sagamu.
The official disclosed that four of the victims with ”more serious injuries” were referred for further checks at Olabisi Onabanjo University Teaching Hospital (OOUTH) Sagamu.
He advised corps members, when commuting, to always caution drivers who drive carelessly especially during the raining season.
He added that if such drivers discard such warnings, commuters should call FRSC toll-free number (122) and officers will take necessary disciplinary action against such erring drivers.
The accident came over a week after some corps members drowned in Taraba while swimming in a river.

Experimental Ebola treatment begins in DR Congo
Global News | Aug. 14, 2018
The Democratic Republic of Congo has started using the experimental mAb114 Ebola treatment on patients in the east of the country, the health ministry said on Tuesday, the first time it has been deployed against an active outbreak.
The outbreak in eastern Congo’s North Kivu province has now spread to neighbouring Ituri province, where a person who was a confirmed case died after returning home from the flare-up’s epicentre in the North Kivu town of Mangina, the ministry said in a statement.
Five new cases have been confirmed, the ministry said, bringing the total number of cases to 57.
The ministry said that 41 people are believed to have died in all from the haemorrhagic fever.
The mAb114 treatment was developed in the US by the National Institutes of Health using the antibodies of the survivor of an Ebola outbreak in the western Congolese city of Kikwit in 1995.
It was 100 per cent effective when tested on monkeys.
The ministry said that several other experimental treatments have arrived in the regional hub of Beni and are awaiting approval from an ethics committee, including Remdesivir, Favipiravir and REGN3450, REGN3471 and REGN3479.

Ways by which soil looses it fertilization



Ways by which soil looses it fertilization 
* Bush burning : This kills many soil microorganisms such as bacteria and worms which are involved with nutrients production.
* Harvesting : When crops are harvested, the nutrients they contain are lost from the soil.
* Soil erosion : This is the  loss of top soil and as such loss of soil nutrients.
* Continuous cropping : Planting of crops from year to year on the same portion of land which leads to loss of nutrient.
* Leaching : When the soil does not retain water well, percolating water carries nutrients beyond the reach of plant roots.
Different types of erosion
Erosion of land can occur in a variety of different ways which includes
1. Water erosion : The beating action of rain falling on wet soil destroys surface aggregate and also reduce the amount of infiltration of water. Once the infiltration rate is exceeded by rainfall, surface run off takes place down the slope.

The longer and steeper the slope, the greater the erosive power of the run off. As it flows down slope, water takes into suspension first the clay and silt and as it picks up speed, it takes up progressively coarse materials.

2. Wind erosion : Wind erosion starts with a process Known as saltation;  which is a sort of jumping motion of the smallest ,most erodible particles or aggregate of soil.

Particles which becomes airborne in gusts of wind fall gradually back to the ground after covering a distance of three or four meters. The impact of these particles hitting the ground moves other particles of similar and larger size.
The larger particles slide and roll along the surface until stooped by ditches while the finer materials are projected higher into the air to form dust clouds.

3. Glacier erosion : Glacier are giant bodies of ice that pick up huge pieces of rock, some even as big as houses. A combination of the water, ice and picked up sediments creates a powerful eroding machine. As more sediment is picked up, the force of erosion becomes greater.

The erosion can smooth out areas that were once rugged and rocky. Glaciers are such a powerful force that they can carve out valleys or create land forms such as deltas.

4. Soil erosion : Flooding, wind etc, can carry the top soil away and make the soil fertile. When forest are cleared for timber or to make room for agriculture, the rate of soil erosion can increase dramatically because trees are no longer there to hold  the soil in place. Increased erosion can cause streams and rivers to become clogged with silt, which harms or kill aquatic animals.

 Also overgrazing  by herbivores can lead to soil erosion because grasses are very efficient in holding down and stabilizing soil..
        Measures to check soil erosion 
* Reforestation  is the restocking of existing forests and woodlands that have been depleted. The tree roots serve to anchor the soil and prevent  erosion.
* Contour plowing is the farming practice of plowing across a slope following its elevation contour lines. The rows formed slows water run-off during rainstorms to prevent  soil erosion.

* planting  of perennial plants which have deep, extensive root systems can help hold soil in order to prevent erosion.

* Terracing is used in farming to cultivate sloped land. Terraced fields decrease erosion and surface run off and are effective for growing crops requiring much water such as rice.

     Ways to conserve soil fertility 
* proper soil management involving an adequate soil conservation program.
* Adding of green manure
* Inclusion of leguminous plants to provide free nitrogen

Maize cultivation



Maize cultivation
Maize is only known in the  cultivated state and is believed to have originated in Mexico in prehistoric times. It currently has world wide distribution and is grown where summer ate reasonably warm.
Africa, Asia, and America are the most likely countries of origin. Processed corn is consumed as a snack or cereal by man and may also be used as silage to feed livestock.
      Soil types preferred by maize
Some of the major soil types preferred by corn include alfisols, entisols and inceptisols.  The soil PH in maize fields range from 5.8 to 6.5 in the alfisol and 6.2 to 8.1 on vertisols.

These soils are characterized by low organic carbon contents, weak soil profile development, coarse or medium textured upper layers of soil and low microbial load attributable to the low organic carbon.

The afisols are prone to high phosphorus fixation. Corn prefers deep, naturally rich, easily tilled soil. The soil should be free from restrictive layers (hard pan) and soils with PH lower than 4.5 should be avoided or corrected by the application of lime.

The most suitable soil type for maize is a soil with good effective depth, favourable physical properties (texture and structure), good drainage, optimal moisture regime and sufficient and balanced  quantities of plant nutrients.
          Method of cultivation
Maize is propagated from seeds. A deep, firm seedbed, free of clods and surface irregularities should be prepared preferably on moderately heavy to heavy soil.  Soil should  be worked and dialed about 3-4 weeks before planting, thus allowing for partial decomposition of organic materials.

Planting depth varies from 5-10cm, depending on the soil type.  Planting should be shallower in heavier soils than in Sandy soils.
Weed control during the first 6-8 weeks after planting is crucial, as weeds compete vigorously with the crop for nutrients and water during  this period.

The presence of weeds during harvest may hinder the process and transmit odors to grain which incurs additional cost for removal.
The visible sign of the maturing maize plant is senescence, dying back of leaves starting from the lower leaves and continuing upwards.

This is the period of grain drying which can progressively be monitored through the kernel milk line. The disappearance of the milk line denotes that the grain has reached physiological maturity. The appearance of the black layer at the tip of the kernel (detachment of kernel from cob)  denotes harvestible maturity.
             Major disease of maize
Some fungal diseases of maize include gray leaf spot (cercospora zeamaydis), anthracnose leaf spot (colletotrichum graminicola), common corn rust (puccinia sorghi).
Solution to diseases
The above fungal diseases can be managed by treating the seed with fungicides, planting when soil conditions are warmer and drier, use of proper planting depth, use of resistant hybrids and crop rotation.

Former Brazil striker Ronaldo hospitalised with pneumonia in Spain
Socceruncle | Aug. 12, 2018

Retired Brazilian striker Ronaldo has been hospitalised with pneumonia on the Spanish holiday island of Ibiza and is recovering well, a local newspaper reported Sunday.
The 41-year-old, widely considered one of the world’s best-ever players, was admitted to the intensive care unit of the Can Misses Hospital on the island on Friday afternoon where he was diagnosed with pneumonia, local daily newspaper Diario de Ibiza reported.
Several hours later Ronaldo asked to be transferred to a private hospital called Clinica Nuestra Senora del Rosario, the newspaper added.
The former Barcelona and Real Madrid player remains in intensive care and but was “evolving favourably”, unnamed hospital sources told the newspaper.
Contacted by AFP, a hospital spokeswoman said she was unable to give any information for privacy reasons.
Ronaldo, who was named FIFA’s world player of the year three times prior to his retirement from football in 2011, is a regular visitor to Ibiza, where he owns a house.
He won his first cap for Brazil as a 17-year-old and went on to score 62 goals in 97 international appearances, including both goals when Brazil beat Germany 2-0 in the 2002 World Cup final.

System development life cycle (SDLC)



System  development life cycle (SDLC)
what is system development life cycle?
The system development life cycle (SDLC) is the traditional system development method that firms use for huge scale IT projects.

 The SDLC is a structured framework that consists of sequential processes by which an information system is developed.
It has the following stages;
* System Investigation /planning
* System Analysis
* System Design
* System Implementation
* System Evaluation
* System Maintenance
Once a development project has the necessary approval from all participants, the systems analysis stage begins.

System analysis is the examination of the business problem that an organization plans to solve with an information system.

The main purpose of the systems analysis stage is to gather information about the existing system in order to determine the requirements for an enhanced system or a new system.

When the system developers have accumulated the user requirements for the new system, they proceed to the system design stage.

The system development life cycle (SDLC) is also a term used in system engineering, information systems and software engineering to explain a process of planning, creating, testing, and deploying an information system.

The systems development life cycle concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both.

SDLC  can be used during the development of an IT project, it describes the different stages involved in the project from  the drawing board, through the completion of the project.

A system development life cycle is composed of a number of clearly described and distinct work phases which are used by system engineers and system developers to plan for design, build, test, and deliver information systems.

     Like for instance like anything that is manufactured on an assembly line, an SDLC aims at producing high-quality systems that meet or exceed customers expectations, based on customer requirements, by delivering systems which move through each clearly defined phase, within the scheduled time frames and cost estimation.

Phylum hemichordata



Phylum hemichordata :

Once grouped as chordates, the Hemichordate are now a distinct phylum.
    They are group of worm like marine animals with apparent and intriguing relationship with the echinoderms and the chordates.
     The acorn worms (hemichordates) are believed to be a link between the vertebrate and invertebrates.
    The hemichordata lacks the notochord which excludes them from the chordates,however,they exhibit the presence  of the pharyngeal gill slits and in some species,a dorsal hollow nerve cord.

Classification  of the phylum hemichordata
The phylum comprises of two classes :
*class enteropneusta
*class pterobranchia

Class enteropneusta : This is a cylindrical, soft bodied and worm like animal with ciliated body surfaces. They are acorn worms.  They are common inhabitants of shallow water, with most species forming mucus lined burrows in Sandy or muddy sediments. The body is long and narrow and is divided into three distinct regions.
 The anterior called the proboscis is followed by a narrow collar regions and then the bulk of the body called the trurik.
The three body regions correspond with typical deuterostome body division:protosome,mesosome and metasome e. g. Balanoglossus, Ptychodera.


Acorn worm(saccoglossu)

Class pterobranchia : They exhibit a dorsal extension of the pharynx,forming an anterior stimichord just like the enteropneusta, which serves to support the surrounding tissues. However, they differ from the enteropneusts by possessing ciliated, anterior tentacles and a U shaped gut. Although, most members of this group have rigid tubes that they secretes e. g. Cephalodiscus.

Phylum echinodermata




Phylum echinodermata:

The echinoderms are mostly marine animals. They include the sea stars, sea lilies, feather stars, star fishes, sea cucumber, sea urchin .some live in oceans and at great depth.

      Echinoderms are the most abundant group of animals that are available on the deep sea floor. Most of  them are slow moving animals and most use the tube feet(podia) for attachment in the bottom of the  sea.

      Although their free living larval stages are bilaterally symmetrical, most adult echinoderms show a basic five -point (pentamerous) radial symmetry. As radially symmetrical animals ,they lack cephalization. Thus adult echinoderms generally do not have anterior and posterior ends. Instead, the body surfaces are designated as being with either oral or aboral.
They have an internal skeleton compose largely of calcium carbonate. Typically, this skeleton bears projecting spines which give the body surfaces a spiny appearance.
       Their most distinctive feature is the WATER VASCULAR SYSTEM which consists of a series of fluid -filled canals. During  locomotion, the water vascular Canal operates like a hydraulic system. Echinoderms lack definite excretory system.

Characteristics of the   echinodermata
* Most echinoderms are typically pentamerous, that is the body is usually with five -radiating areas.
* They have skeleton  made of calcareous materials. The exoskeleton carries spines on them.
* The digestive tract is complete.
*Most echinoderms are dioecious (sex are separate) and fertilization is commonly external.

Classification of the phylum echinodermata

There are quite  a huge number of classes but five (5) classes of existing echinoderms are usually recognized

* Class of Asteroidea
* Class of Ophiuroidea
* Class of Echinoidea
* Class of Holothuroidea
* Class of Crinoidea

Class of asteroidea: They are the star fishes. They possess arms and a basically star-shaped body.

Class of Ophiuroidea :They are the brittle stars and the basket stars. They lack the anus and the tube feet lack suckers.

Class Holothuroidea :They are the sea cucumber. They are soft bodied animals. They have slender bodies which are elongated at both ends.

Class of Crinoidea : The Crinoids are the most primitive. They include the sea lilies  and the feather stars.

Class of Echinoidea :These are the sea urchins and the sand dollar. They are heart-like in shape  and the tube feet end with suckers.

Preservation of animal species




preservation of aninmal species
Preservation of animal species 

Preservation  can be defined  as the use of chemical, physical or other            Processes to prevent  microbial
and physical damages to biological specimens with a view of retaining their  original  form and prolonging their  storage life.

    The procedure  for preservation of animal  specimens varies greatly from  one animal group  to another.
      In most cases, the animal must first be killed or narcotised in a suitable  way so as to leave the tissues  in a state ,which is proper for display.
     The specimen is then fixed in this  condition and finally preserved. This final preservation is normally made either in a solution of ethanol or methanal (formalin).

Techniques  in fixing and preserving animal materials
     Fixation is a chemical process, which stops autolysis  and stabilizes protein components of tissues so that in
subsequent processing the tissue retains as fully possible the form they had in life.
     Preservation allows materials to be stored indefinitely by destroying any microbial action, which could degrade the specimen.
    The choice of fixation will depend upon the animal material to be fixed and the purpose for which it is being fixed.
Narcotisation :This is also known as relaxation and is an interim technique for animals since many are highly contractile and assume  grossly distorted  postures if placed straight into fixative.

The main factors to be considered in 

Speed of penetration : This determines the size of specimen that can be fixed.
Hardening: Some chemical like ethanol  is particularly liable to cause tissues to harden on prolonged exposure to high concentration.
Shrinkage :Certain fixatives such as ethanol and mercuric chloride  cause  tissues to shrink thus distorting the specimen  significantly.

Preservation techniques

Wet preservation : Fhis is used mainly for animals and is usually preceded by narcotisation. The process of fixation is then comparatively straight forward. Most times, it is necessary to arrange the body and appendages of the animals using tape.

* A 5-10%v/v aqueous solution of formalin(=40% v tv aqueous  formaldehyde neutralized with calcium carbonate to prevent any acidity in the solution resulting in the slow dissolution of calcareous  structures.)
*50-70% ethanol : Ethanol is inflammable, highly volatile and tends to cause shrinkage and decolorization in soft bodied animals. Pass  them slowly through a graded series of concentrations to minimize this problem.

Dry preservation
This form of preservation is used mainly for vertebrate taxidermy and for arthropods  and other invertebrate species. The hard exoskeleton of arthropods are easily preserved in dry state since the skeleton  prevents collapse and loss of form upon drying.

Taxidermy : it is a type of dry mounting where the vertebrate is carefully skinned to remove the body and then replace with false body made of polystyrene, foam or cork etc.

Storage : Careful maintenance of specimen after fixation /preservation process is very important. The storage conditions for materials preserved either in wet or dry state.

Labelling : labelling must be comprehensive and contain information on the fixative and preservation processes  as well as ecologically and taxonomic details.

Reasons for animal preservation
* it prolongs the storage life of the  specimens.
*it prevents  the attack of micro–organisms like bacteria  and fungi that causes  spoilage.
* it helps in the preservation of large quantities of specimen needed for laboratory studies.
*extinct animals specimens can be preserved  for future study.

fractional distillation of crude oil




fractional distillation of crude oil 

In the fractional  distillation of crude oil,the crude oil is heated above 400c and pumped
into the fractionating column where the components condense at their respective boiling  points.

         Conversion process
Conversion processes are the technique that are used to  improve  the quality of petrol product  after  initial distillation.

The techniques  used are:
* Hydro treating
* Catalytic  reforming
* Catalytic cracking

   Hydro treating: It is a refining process for removing sulphur  and other undesirable  elements from  petroleum  products.

       Catalytic reforming : catalytic reforming is a chemical process used to  covert linear hydrocarbons to high brand hydrocarbon.

Catalytic cracking :This is the  breakdown of higher molecular weight petroleum fraction into lighter ones with the use of catalyst.
It can yield  petroleum of higher octane number. Example of octane
number is 2,2,4 trimethylpentane
