This is a question on my homework and I keep getting the wrong answers. Please help me with detailed answers to all four parts.
Consider an annual plant which germinates in the spring, blooms in the summer and produces S seeds in the autumn.
A fraction f of these seeds germinate the next spring, ﬂower and produce more seeds. Of those that do not germinate, a fraction g germinate the second spring, ﬂower and produce more seeds. There are no seeds that survive more than two winters.
(a) Let Pn be the plant population in year n. Write a second order linear diﬀerence equation satisﬁed by Pn. Explain the role of various terms occurring in the equation.
(b) Find the general solution of this equation.
(c) Suppose that in the ﬁrst summer you have 80 plants and no extra seeds. Determine the solution Pn after n years as a function of S, f and g.
(d) Let f = 0.014, g = 0.006. Discuss the limiting behavior of the general solution as a function of S. How large should S be to ensure that the plant population eventually increases in size?

Causes of Parturition in Cattle
1.0 Introduction Parturition in cattle is known to be a complicated physiological process, where the onset is generally accepted to be initiated by the fetus (Thorburn et al., 1977; Thorburn, 1979). In normal circumstances, this complicated process involving several hormonal interactions and should conclude without any human interference, leaving a healthy cow with a vigorous calf. However, in reality a large proportion of calving require assistance to varying degrees that may result in a stillborn calf (Meijering, 1984). Domestication and breeding programmes in the dairy industry select for cows that produce calves that are relatively larger when compared to their dams; a regular occurrence in cattle compared to most other mammals (McClintock, 2004). As dystocia is highly related to the pelvic area (Price and Wiltbank, 1978), being able to measure the pelvic dimensions is beneficial. The process of measuring the internal and external capacity and diameter of the pelvis is known as pelvimetry (Studdert et al., 2011). This is elucidated in studies which reveal that there is value in using external pelvimetry as a predictor for the internal pelvic measurements (Murray et al., 2002), while others show that withers height and heart girth were the best predictors of internal pelvic sizes (Kolkman et al., 2012; Coopman et al., 2003). Hence, it would be easier if the farmer had an alternate method to measure internal pelvic dimensions, such as predicting those dimensions through measurements of external morphometry which could be done directly using measuring tape. Therefore, the ability to accurately determine the possibility of dystocia will allow early and appropriate intervention, which then decreases the morbidity and mortality of the dam and fetus, improving animal welfare and reducing economic losses (Linden et al., 2009). There is a need for information regarding associations between internal pelvic measurements and external morphometry, which may have value in determining dams with larger pelvic opening that increases calving ease (Bellows et al., 1971). Currently, no research has been done to study the association between the intrapelvic measurements and the external morphometric measurements in Friesian cross cattle in Malaysia. Hence, the objective of this study was to determine the relationship between intrapelvic area, morphometric measurements, age, body weight and body condition score in Friesian cross cattle which could be of value in determining dams with larger pelvic openings and thereby reducing the risk of dystocia. It is hypothesized that there is an association between the intrapelvic measurements and external morphometry in Friesian cross cattle. 2.0 Literature Review 2.1 Dystocia Dystocia, defined as delayed or difficult parturition (Mushtaq, 2016), is usually classified into two main causes which are direct factors and indirect factors (Meijering, 1984). The former usually being anatomical and physiological factors such as malpresentation of the calf in the birth canal and uterine torsion in the dam. The latter is related to phenotypic effects that are related to the calf such as calf birth weight, multiple calvings and perinatal mortality, as well as, phenotypic effects associated with the cow such as cow pelvic area, cow body weight at calving, cow body condition score, gestation length and calving assistance. Indirect factors also include non-genetic factors such as cow age, parity of cow, calf sex, nutrition and other disorders, while genetic factors involve cow, bull and calf breeds (Zaborski et al., 2009). The most common cause of dystocia is a physical incompatibility between the size of the foetus and maternal pelvic size, also known as feto-pelvic incompatibility. The pelvic size of the dam is mainly influenced by the stage of maturity of the cow. As a result, a smaller size of the pelvis contributes to the higher incidence of dystocia in heifers (Haskell and Barrier, 2014) and vice versa where dams with larger pelvic openings experience less calving difficulty (Barrier et al., 2013). 2.2 Breed Comparisons Several studies have shown that there are significant differences in pelvic dimensions between breeds of beef and dairy cattle (Ramin et al., 1995; Laster 1974; Meijering and Pastma, 1984; McElhenney et al., 1985). There are also differences between herds within breeds, purebreds and crossbreeds, and small breeds and large breeds. The pelvic height and pelvic width increase greatly with advancing age, which shows that the pelvic area is larger in mature cows in comparison to heifers. The mean pelvic heights in beef and dairy heifers can vary from 13.5 cm to 19.3 cm, the pelvic width from 12.6 cm to 18 cm, and the mean pelvic area from 170 cm2 to 290 cm2. 2.3 Impact of Dystocia on Dam The occurrence of dystocia has shown to have an adverse effect on the reproductive performance of dairy cows, where the first oestrus, days open and the calving interval were significantly longer (Gaafar et al., 2010). Fertility is further impaired as a result of dystocia as it causes a reduction in conception rate and an increase in the number of services per conception (Lopez de Maturana et al., 2007). Total milk yield also tends to be lower in cows that have experienced dystocia at calving compared to those that calved normally (Berry et al., 2007). Furthermore, there is a significant increase in the mortality rate of cows experiencing dystocia in comparison to those that calved without assistance and the number is highest in cows that require serious intervention during parturition (Dematawewa and Berger, 1997). 2.4 Impact of Dystocia on Calf Majority of stillbirths were reported to be a direct result of dystocia (Meyer et al., 2000; Lombard et al., 2007). During parturition, there are several dramatic physiological changes that can have adverse effects on the foetal oxygen concentration (Lombard and Garry, 2013). The foetus can experience neonatal asphyxia during the calving process due to hypoxia, decreased blood flow as a result of occlusions of the placenta, or ischaemia. Hypoxia can progress to anoxia, which can be prolonged with instances of dystocia resulting in foetal death (Bluel et al., 2008). The calf can also have hypercapnia, which can cause respiratory acidosis. However, during dystocia the respiratory acidosis will be pronounced and in addition to this, the hypoxia can lead to anaerobic metabolism within the body that results in metabolic acidosis. The acidotic condition of the foetus can negatively affect the central nervous system resulting in lowered vigour, depression and decreased physical activity, which is referred to as ‘weak calf syndrome’ or ‘dummy calf syndrome’ (Ravary-Plumioën, 2009). The dystocic calves were slower to express most of the neonatal behaviours, particularly those that lead up to reaching the udder, and usually lay recumbent (Barrier et al., 2012). This results in the failure of transfer of passive immunity as the calf is unable to absorb an adequate quantity of colostrum (Johnson et al., 2007; Weaver et al., 2000). This has been linked with an increase in calf morbidity and mortality and a reduction in the calf growth rate (Robison et al., 1988; Donovan et al., 1998). 2.5 Economic Impacts In a United Kingdom dairy herd, the total cost of a slightly difficult calving was estimated to be roughly £110, while a more serious difficult calving can range from £350 to £400. This takes into account the labour and veterinary costs, including the cost of caesarean deliveries, the mortality of dams and calves and the culled cows, the losses incurred due to a decreased milk production and poor reproductive performance (McGuirk et al., 2007). In Australian Friesian Holstein herds, the cost of dystocia for a herd can go up to $5100 per year, where 30% of the losses is due to reduced fertility, 20% due to culling or dam death, veterinary costs were about 10% and labour costs were 20%. The cost of dystocia in primiparous cows was about $48.49, while it was $19.15 in mature cows. The overall losses associated with calving difficulties in the Australian dairy industry can be estimated to be in excess of $44 million annually (McClintook, 2004). In a study by Dematewewa
The Women In Love – Essay
Women in Love is a novel about two young ladies, the Brangwen sisters, Urusula and Gudrun and how they fall in love and lead two completely different relationships with the men they meet, Rupert Birkin and Gerald Crich, with who they gradually fall in love. Birkin, a school inspector, visits Ursula who teaches at the school however Hermione, the woman previously involved with Birkin, intrudes on their conversation and invites Ursula and Gudrun to stay with her in Breadalby. Ursula and Gudrun travel to Breadalby to stay with Hermione where Gerald officially meets the two. He saw them again, while they were at home waiting for the train to pass. This sets an awful impression of Gerald to the sisters as he was torturing a horse, training her to withstand the fear. The Brangwen sisters then see Gerald again, whilst sketching along side Wiley Water. He was with Hermione who caused commotion between Gudrun and Gerald after dropping her sketchbook in the water. In the meantime, Ursula had wandered off towards the hill where she met Birkin “sawing and hammering away.” This was the first sign of a relationship between the two and he eventually sent a note to invite the sisters to tea. Feeling desire for Birkin to speak only to her, she didn’t tell Gudrun about the invite where they discuss the concepts of love and their feelings. The couple met again at Mr. Crich’s annual water-party on the lake. Gerald organises a small boat for Gudrun and Ursula who row to a little stream. After hours on end, the men arrive in worry. The four begin to row back to the estate but Gerald’s sister, Diana, drowns causing grief for the Crich’s. Gudrun then becomes the teacher of Gerald’s youngest sister, Winifred. There relationship was a tight bond and soon she moves into a studio which was built for the two girls. After many thought and consideration, Birkin visits the Brangwens to ask for Ursula’s hand in marriage however Birkin left without an answer. Enraged, he walks to Shortlands where he finds Gerald. Ursula then meets with Hermione who belittles Birkin and encourages Ursula not to marry him. Birkin then buys Ursula three rings which leads her to agreeing to marriage. Mr. Crich sadly then passes away and after the funeral, in devastation Gerald spends the night with Gudrun. Gerald then thinks about marrying Gudrun and he suggests for the four to travel to the Tyrol although Birkin and Ursula left early to Verona. Gerald is infuriated by Gudrun’s verbal abuse and her refusal of his manhood as well as Loerke who Gudrun begins a friendship with. On the slopes, Gerald strangles Gudrun yet let go when Loerke called for him. Gerald continued up the slope but he slipped and fell and “immediately went to sleep.” His body was returned to England to be buried, together with Ursula and Birkin. Gudrun went to Dresden to visit Loerke. The impact of Gerald’s death on Birkin was inevitable, he loved him just as much as he loved Urusla however Ursula could not understand this. Narrative Style This novel is written in third person singular with an omniscient style. “It pleased Ursula, what he said, pleased her very much. She herself knew too well the actuality of humanity, its hideous actually.” The pronouns ‘he’ and ‘she’ are frequently used and characters are continuously addressed by their names. Character Analysis Ursula: is an independent, strong-willed lady who doesn’t enjoy being told what to do. She likes to make her own decisions, no matter what the situation. This is shown through the conversation held between, herself, her father and Birkin when he proposes to her; “‘You both want me to force me into something’ ‘That is an illusion of your own’.” She also needs certainty to make those decisions which is shown through her constant questioning of if Birkin loves her. She is reliable for Birkin as she devotes her everything to him however she seems to misunderstand the importance of a relationship between the men and seems she is jealous that Birkin doesn’t only need her. Gudrun: is a very kind and compassionate woman as she takes the time and effort to sit with Winifred and paint. Her loving character is shown when she feels uneasy about telling Winifred that her dad will die when asked what she thinks. She isn’t a trustworthy person as she leaves Gerald for Loerke in the Alps and feels what Gerald and she had, was over although Gerald didn’t feel this way. Birkin: has an aspect of a true gentleman. This is shown through his love and devotion to Ursula because he states that he doesn’t want to serve him; “I who am at the beck and call of the woman, than she at mine.” His love for Ursula and Gerald also shows that he can maintain love with romance and love with friendship; “eternal union with a man too: another kind of love.” Gerald: is a determined man as he has hope that his sister was still alive when he tries to save her and he never gives up. These experiences made Gerald the strong, determined man he was, as he had suffered of loss of those close to him. However he is not independent as when his father passes away he finds himself at the graveyard then walks to Gudrun’s house seeking comfort and affection. Gerald is also a proud character as he is proud of his estate that his father owns and doesn’t let the past affect his present. Language
