Geological notes and local details for 1:10 000 sheet TG 32 NE (Lessingham) : part of 1:50 000 sheet 148 (North Walsham)
The following report is designed to be used in conjunction with 1 : 10 000 Geological Sheet
TG 32 NE. Uncoloured copies of the map may be purchased fkom the Survey's headquarters
at Keyworth. The district covered by the map is included in 1 : 50 000 Geological Sheet 148
(North Walsham). It formed part of Old Series One-Inch sheet 68 E, and was surveyed at a
scale of 1 : 63 360 by C Reid in 1877-1878. The district was resurveyed at 1 : 10 000 scale
by the present author in 1995, with Dr I R Basham as regional geologist.
The area lies to the north-east of Norwich, and just touches the coast at Cart Gap which lies
between Happisburgh to the north and Eccles on Sea to the east (Figure 1). The market town
of S t a b lies on the southern border of the district, and the villages of Inghm and
Lessingham lie within the eastern part of the district. The remainder of the district is rural,
and includes parts of the parishes of Brumstead and East Ruston. No major rivers drain the
district, but the River Ant passes just to the west; this flows southwards into the area known
as the Norfolk Broads to join the Bure and ultimately drains to the sea at Great Yarmouth.
The un-named steam which flows to the east of Lessingham rises just to the north-east of the
district and continues southwards via the New Cut, Horsey Mere, Meadow Dyke, Heigham
Sound and the River Thme to join the Bure at Thurne
Geological notes and local details for 1:10 000 sheet TG 22 NE (Westwick) : part of 1:50 000 sheets 147 (Aylsham) and 148 (North Walsham)
The following report is designed to be used in conjunction with 1 : 10 000 Geological Sheet
TG 22 NE. Uncoloured copies of the map may be purchased fiom the Survey's offices at
Keyworth. The district covered by the map is included in 1 : 50 000 Geological Sheets 147
(Aylsham) and 148 (North Walsh). It formed part of Old Series One-Inch sheet 68E, and
was surveyed at a scale of 1 : 63 360 by H B Woodward in 1879. An accompanying memoir
was published (Reid, 1882). The district was resurveyed at 1 : 10 000 scale by the present
author in 1996-7, with Dr I R B a s h as regional geologist.
The area lies to the north of Norwich (Figure 1). The market town of North Walsham extends
onto the northern part of the sheet, and Worstead into the south-eastern corner. Apart fiom
this the area is predominantly rural, with the small settlements of Westwick, Swanton Abbott
and Skeyton in the south. In the north of the area the land rises to a plateau, with maximum
altitudes of over 40m OD at Lord Anson's Wood [26 281 and North Walsham [28 291. Small
streams drain this plateau to the west, south and east, including Skeyton Beck in the northwest
and Stakebridge and Westwick becks in the south. All are tributaries of the River Bure,
which flows into the area known as the Norfolk Broads and ultimately drains to the sea at
Great Ymouh. In the east the ground drops away rapidly into the valley of the River Ant,
a major tributary of the Bure.
In general the high plateau formed by the sands of the Corton Formation, which is very well
drained, forms poor agricultural land and is traditionally grazed by sheep, hence the
importance in medieval times of cloth manufxture in the village of Worstead. Nowadays
much of this higher land is given over to commercial woodland and pheasant rearing. The
remainder is wed for arable crops but requires intensive irrigation. However, some areas of
the Corton Formation outcrop, particularly at lower levels, are covered by up to rather more
than a metre of cover silt, and these areas, along with the outcrop of the Crag Group, produce
excellent agricultural land, neither too heavy nor too light. Large crops of wheat, barley, sugar
beet and potatoes are grown, and owing to the water-retentive properties of the cover silt,
little artificial irrigation is required despite the low rainfall in this part of the country. The
alluvium and peat outcrops of the Stakebridge Beck and Westwick Beck are given over to
woodland and permanent pasture, grazed by cattle, sheep and horses.

Management Safety Climate And Violence Prevention Climate: A Mediational Model For Healthcare Employee Outcomes
Workplace violence is defined as aggressive acts against employees ranging from verbal abuse, threats, and bullying, to physical assault (OSHA, 2002; Jackson, Clare, & Mannix, 2002). The two purposes of this study were (1) to differentiate two specific forms of psychological climate related to workplace violence on a work unit: Violence Prevention Climate (VPC) and Management Safety Climate (MSC), and (2) to test a causal model focusing on the relationship between these climates and their effects on relevant outcomes for at-risk employees in the healthcare industry. MSC was expected to partially mediate the effects of VPC on four outcomes: work satisfaction, work-related exhaustion, workplace violence exposure, and the perception that workplace violence is a problem for the individual. Two samples were used to compare the differences between these relationships in two scenarios: within a single hospital system after identifying work units at increased risk for workplace violence, and within a multitude of U.S. healthcare organizations. Using structural equation modeling, results revealed slight variations in the final model structure between the two samples. The majority of hypotheses were supported, and implications for practice and research are discussed
Maximal Denumerant of a Numerical Semigroup With Embedding Dimension Less Than Four
Given a numerical semigroup and , we
consider the factorization where
. Such a factorization is {\em maximal} if is a
maximum over all such factorizations of . We show that the number of maximal
factorizations, varying over the elements in , is always bounded. Thus, we
define \dx(S) to be the maximum number of maximal factorizations of elements
in . We study maximal factorizations in depth when has embedding
dimension less than four, and establish formulas for \dx(S) in this case.Comment: Main results are unchanged, but proofs and exposition have been
improved. Some details have been changed considerably including the titl
In the absence of CD154, administration of interleukin-12 restores Th1 responses but not protective immunity to Schistosoma mansoni
The cytokine interplay during the development of protective immunity to the radiation-attenuated (RA) schistosome vaccine has been extensively characterized over recent years, yet the role of costimulatory molecules in the development of cell-mediated immunity is much less well understood. Here we demonstrate the importance of CD40/CD154 in vaccine-induced immunity, as CD154(-/-) mice exposed to RA schistosomes develop no protection to challenge infection. We showed that vaccinated CD154(-/-) mice have defective Th1-associated immune responses in the skin-draining lymph nodes and the lungs, with reduced or absent levels of interleukin-12p40 (IL-12p40), gamma interferon, and nitric oxide, but elevated levels of lung IL-4 and IL-5. The expression of major histocompatibility complex II (MHC-II) on antigen-presenting cells recovered from the lungs of vaccinated CD154(-/-) mice was also severely compromised. The administration of anti-CD40 monoclonal antibody (MAb) to CD154(-/-) mice did not reconstitute sustained Th1 responses in the lymph nodes or the lungs, nor did the MAb restore anti-parasite immunoglobulin G production or protective immunity. On the other hand, the administration of recombinant IL-12 (rIL-12) to CD154(-/-) mice shortly after vaccination caused elevated and sustained levels of Th1-associated cytokines, rescued MHC-II expression by lung CD11c(+) cells, and restored the appearance of inflammatory effector foci in the lungs. However, the treatment of CD154(-/-) mice with rIL-12 did not restore protection. We conclude that protective immunity to the RA schistosome vaccine is CD154 dependent but is independent of IL-12-orchestrated cellular immune mechanisms in the lungs
