Abstract:
he column adsorption study examines irrigation water treatment prior to its application in order to ensure water-crop-consumer heavy metal transfer reduction to the safe level using locust bean husk char (LBHC) as biosorbent. Char structural pattern was investigated with SEM-EDX machine. Contaminated surface water was introduced simultaneously into the bioreactors containing 100 and 200 g of LBHC and collected after 30, 60, 90 120 and 150 min of detention time. Removal efficiency, isotherm and kinetic sorption model were the evaluation tools for the study. Percent of Cr, Cd and As removal at 150 min retention time were 83.33, 100 and 100%, respectively for 100 g biosorbents. A similar trend was observed for Cr and As removal at the same retention time for 200 g of LBHC. Metals sorption conforms to the Freundlich isotherm with correlation coefficient values greater than 0.92. Experimental kinetics had a good fit for pseudo second order (R<sup>2</sup> &gt; 0.94 for most cases). Removal efficiency is a function of contact time, biosorbent dosage and metal concerned. Locust bean husk char has good and effective treatability for some heavy metals in mildly polluted water.

Abstract:
The study aimed at providing information on consumer preference and reasons for consumption of processed locust bean in kano State, Nigeria. Data were collected with the aid of questionnaire. Multistage sampling technique was used in selecting 70 respondents. Descriptive statistics was used to analyze data collected. Locust bean consumption was mainly (88.6%) carried out by men in which majority (35.7%) were 38-47 age group, mostly (94.3%) married with majority (44.3%) having informal Qur’anic form of education. Majority (65%) of the consumers source their locust bean condiment for consumption from the producers and the consumer preference majority (88.6%) prefer the cake than ball form (11.6%) while reason for locust bean consumption was mainly due to (57%) improve food taste. Consumers mean expenditure on processed locust bean was N30.00 and N172 for daily and weekly respectively. Major constraints identified by the consumers in the consumption of processed locust bean include inappropriate packaging (38.6%0, poor hygiene (27.1%), product adulteration (17.7% and pungent smell (16.7%). It was recommended that more sanitary measures have to be taken by the processors to improve hygienic condition of the processing environment and thus acceptability.

Abstract:
This study presents the experimental investigation carried out on the compressive strength and water absorption properties of lateritic blocks stabilized with cement and locust bean pod extract. Tests were carried out in which different sample batches of cement blocks (0.1, 0.2, 0.3, 0.4 and 0.5kg) were moulded and different sample batches of locust bean pod extract blocks (50, 100, 133, 150 and 200g/litre) were moulded and with both cement and locust bean pod moulded too. The compressive strength of the lateritic block samples were tested at 28 days. The results indicated that the cement with locust bean pod extract significantly increase the compressive strength of the lateritic block samples. This compressive strength increases as the amount of cement and locust bean pod extract was increased. This is a validation of the high possibilities of both cement locust bean pod extract being utilized as a binder in the production of blocks for low housing construction in developing areas of Nigeria.

Abstract:
This thesis reports data on blends of carrageenan (0.3%w/w) and locust bean gum (0.3%w/w) in the presence of biopolymers, particularly gelatin of varying concentration. Particular attention is given to their behaviour on autoclaving since this is relevant to one of the most important applications of these materials as gelling agents in canned meat products. It was shown there is such 3% gelatin could be found in the gelling system as a result of from collagen in the meat. Gelatin at this level generally reduced the strength of non-autoclaved carrageenan and LBG gels but enhanced autoclaved gels. Studies of turbidity and rheology suggested that the effect was due to phase separation. Investigation of viscosity after autoclaving produced evidence to support the hypothesis that gelatin protected LBG from thermal degradation. For industrial LBG this was not, however, observed by direct molecular weight measurement, although such effects were seen for pure LBG. Interesting differences between the gel strength response between low and high ionic strength buffers were found. It was concluded that textural performance in real products was sensitive to a range of factors (salt, impurities, presence of gelatin) and would be interpreted by a combination of degradation and phase separation theory. Implications for the industry are discussed.

Abstract:
Aqueous dispersions of xanthan and locust bean gum, in combination, show a synergistic increase in viscosity. At sufficiently high concentrations, firm gels are formed, although neither component forms true gels when alone. The actual molecular processes resulting in this phenomenon are still incompletely understood and Theological studies can provide some clues to the mechanism of the interaction. Rheological properties of the polysaccharide blend were therefore investigated. Moisture, ash and inorganic elements and protein content as well as the intrinsic viscosity of the individual polysaccharides were determined. Dynamic viscoelastic properties of dispersions prepared from the polysaccharide blend were evaluated in four solvent treatments capable of disrupting weak intermolecular bonds. The effect of polysaccharide concentration, temperature, ionic strength, pH, ratio of mixing of the two gums and urea concentration on steady shear rheological properties were evaluated in a fractional factorial experiment. More detailed studies were carried out on the effects of temperature at two levels of concentration and ionic strength. Solvent treatments significantly affected the viscoelastic properties of xanthan-locust bean gum solutions. At 20°C and under the conditions used, dipole interactions appeared to be the primary force responsible for stabilizing the xanthan-1ocust bean gum interacting system. Hydrogen bonding and hydrophobic interactions seemed to play less important roles. Under conditions of low ionic strength and increased temperature, the interactions were lost and polysaccharide solution behavior passed from that of a viscoelastic solid to that of a viscoelastic liquid. At 60°C and at high ionic strengths, hydrophobic interactions may become important in the stabilization of the three dimensional gel network. Temperature effects on steady shear viscosity of xanthan-locust bean gum solutions were dependent on the concentration and ionic strength of the system. In general, steady flow properties were comparable to the reported behavior of xanthan solutions and so reflected the weakness of the interaction (dipole interactions) between the two polysaccharides.

Gums are water-soluble polysaccharides used in many industrial and food applications because of their functions such as thickening, gelling, emulsification, adhesion, and encapsulation. Interactions between gums are conducted to enhance functional properties of finished products and reduce processing costs. In this study, camelina gum, from the oil-seed plant Camelina sativa, is characterized by carbohydrate composition and morphological, thermal, and rheological properties. Interactions with xanthan gum, galactomannans guar gum, and locust bean gum (LBG) are also studied. Camelina gum is composed of arabinose, rhamnose, galactose, glucose, xylose and mannose; according to high-performance anion exchange chromatography analysis. Scanning electron microscopy and transmission electron microscopy images showed camelina gum with fibrillar structure and intermeshed network. Camelina gum solutions exhibited a shear thinning flow behavior in a range of concentrations (0.1% to 2.0% w/w) and shear rate (0.001 sˉ¹ to 3000 sˉ¹). Camelina gum is temperature independent at temperature ranges from 4 °C to 90 °C. The apparent viscosity increased as gum concentration increased. Mechanical properties of camelina gum demonstrated viscoelastic behavior with entangled molecular chains. Interaction of camelina gum with monovalent salt NaCl significantly reduced the viscosity of camelina gum solution at 1% when NaCl concentration increased. Camelina gum is soluble in water up to 60% ethanol content, in which the rheological properties do not significantly differ from camelina gum in water solution only. A synergy with xanthan and galactomannans was determined. All mixtures exhibited shear-thinning flow behavior, solid-like behavior at low frequencies, and liquid-like behavior at high frequencies. For camelina-galactomannans mixtures, synergistic interactions occurred in LBG-camelina mixtures at ratios of 1:1 and 3:1. For xanthan-camelina mixture, maximum synergy was observed at the ratio 1:1. Synergistic effects of gum mixtures suggest dependency on the ratios and chemical structures of the gums. The effect of temperature on apparent viscosity of mixtures is not significant. Results showed that camelina gum can be used for commercial applications.

Abstract:
The purpose of this research was to determine whether all-purpose flour could be partially replaced with locust bean gum (LBG) and guar gum, and produce an acceptable bread product. A pilot study determined that up to 4% gum replacement for flour was feasible. All bread treatments were evaluated objectively by standing height, texture, color, and cell size. Moisture determinations were obtained for each bread variation. Sensory quality was examined by consumer testing. The amount of heat required to break the hydrogen bonds in amylopectin, indicative of bread staling, was measured by differential scanning calorimetry (DSC) for all bread treatments. Two percent LBG replacement significantly increased standing height. Firmness of bread increased with an increase in gum; the 4% guar bread was significantly firmer. Crumb color was not significantly different for any of the five bread treatments. Crust color, however, was significantly lighter for the control in comparison to the 2 and 4% guar, and 4% LBG breads. Two percent guar produced a more even cell size distribution throughout the bread crumb. For all 5 bread formulations moistures were not significantly different. Sensory evaluation determined a significant difference between the control and 4% LBG. The 4% LBG bread was preferred, although not significantly. Both gums were found to retard bread staling and 2% LBG was the most effective in lengthening the shelf life of the bread product. Objective and sensory evaluation indicated both gums produced acceptable bread products for consumer consumption and possible use in further research.

Abstract:
Rather than being unitary actors, each party is a political system in itself, with three major “faces”: the party in public office; the party central office; and the party on the ground. Over time, the balance of power within parties has shifted, to support the dominance of the party in public office. This evolution has been accompanied by institutional changes, and it has been supported by the growing similarity of the positions of members of the party in public office (responsibilities of governing; exigencies of professional political careers) regardless of the political complexion of their parties or the demands of their members.

Abstract:
This chapter focuses on the phrase structural representation of the most embedded portion of a natural language sentence. It is argued that this corresponds to the core event building domain, and that it has both syntactic and semantic integrity within the sentence. However, the little v label across frameworks and research programs has also been used as the locus for the external argument, as well as for the first cyclic domain for syntactic locality. However, empirical evidence points clearly to a separation of the different functions often ascribed to “little v.” Specifically, it is argued that event structure decomposition head (roughly, Cause) must be clearly separated from, and hierarchically lower than, the head providing the choice of external argument. However, it will be shown from the evidence of the English progressive that this external argument locus is much more abstract and cannot be identified with the traditional category of Voice.

Abstract:
A range of epidemiological studies have clearly established that susceptibility to rheumatoid arthritis (RA) is determined by both genetic and environmental factors. Studies over the last five decades have used a variety of approaches to identify the genetic variants associated with disease. HLA DRB1 was the first RA susceptibility locus to be discovered and has the largest effect size. We describe current understanding of the complexities of HLA association for RA. Linkage and small-scale association studies prior to 2007 provided convincing evidence for only one more RA susceptibility locus, PTPN22. Major breakthroughs in high-throughput genotyping and systematic discovery and mapping of hundreds of thousands of single nucleotide polymorphisms (SNPs) led to large-scale genome-wide association studies used for the first time for RA in 2007. This approach has had a dramatic impact on our knowledge of the susceptibility loci for RA, such that over 60 risk variants have now been robustly identified. We present an overview of these studies and the loci that have been identified. We consider how this knowledge is contributing to a greater understanding of the aetiology and pathology of the disease and in turn how this can influence management of patients presenting with an inflammatory arthritis. We consider some of the unanswered questions and the approaches that will need to be taken to address them.

Abstract:
Rett Syndrome (RTT) is a neurodevelopmental disorder that predominantly affects females but males with RTT have been identified. RTT was first described by an Austrian pediatrician, Andreas Rett. Rett syndrome was mapped to chromosome Xq28 in 1998 and a year later it was determined to be due to mutations in the MeCP2 gene at this locus. Identification of the gene led to the broadening of the clinical phenotype and further characterization into classic and atypical forms of the disease that overlap with Autism spectrum disorders during the period of regression. More than 95% of individuals with classic RTT have mutations in the MeCP2 gene.

Abstract:
Abstract This book chapter describes the advantages and limitations of the ITS Region as a universal barcode for fungal identification. The ITS region offers several practical advantages as a universal fungal barcode region. The region encompasses segments that permit resolution at different taxonomic levels as it includes the highly conserved 5.8S rRNA gene, the moderately rapidly evolving ITS2 region and the rapidly evolving ITS1 region, flanked by the highly conserved SSU and LSU genes which permit design of PCR primers that are almost panfungal. Over the last two decades the sequence-based identification of fungi has certainly come of age. The ITS region is universally accepted as the primary fungal barcoding region owing to the high barcode gap with the locus for many groups of fungi. Since the species-resolution power of ITS is poor for certain groups of fungi, and higher-level taxonomic resolution is greater with proteincoding genes, the TEF1α locus has been proposed as the universal secondary barcode region. In addition, the historical problems surrounding the reliability of fungal DNA sequences in centralized repositories are slowly being resolved by the development of an increasing number of publicly accessible, curated databases.

Abstract:
Dependency of results of structural analysis on constitutive equations obstructs the application of inelastic analysis methods to design. To overcome this difficulty, a realistic inelastic analysis approach assisted by the stress redistribution locus (SRL) has been proposed for the purpose of design application. The basis of this approach is the existence of an unique SRL in each structure. The final goal of this study is to assure the uniqueness of SRL. To clarify control mechanisms of SRLs in structures, elastic-plastic and elastic-creep behaviors of fundamental structures are analyzed. The first model is a stepped bar model subjected to a tension load. The second one is a stepped beam model subjected to a bending load. It is revealed that the elastic cores control SRLs in structures, therefore that SRLs are independent of constitutive equations. Structures with large elastic cores have steep SRLs because elastic cores constrict strain. When elastic cores are reduced, SRLs gradually change from steep to gentle as the constraint becomes weaker. Under bending load, elastic cores shrink to the neutral axis in the same way. Therefore, many structure mainly subjected to bending load have similar SRLs.

Abstract:
A mathematical model of the locust hind leg extensor muscle is presented. The model accounts for the force response of the muscle due to individual stimuli under isometric conditions. Experimental data was collected by stimulating the muscle directly and force measured at the tibia. Joint dimensions were calculated, enabling tibial force to be converted into muscle force. In developing a model it was assumed that the response to a single isolated stimulus was linear, but no assumptions were made about the model order. Models of various order were fitted using time and frequency domain methods to data obtained from well-separated input pulses. The response could be approximated as an impulse response, with the response to each stimulus best described by a linear third-order system. Responses where input pulses were not well-separated, so that summation of subsequent pulses occurred, were also investigated. As has been observed in mammalian muscle, both facilitation and force depression were evident in locust muscle. The linear third-order model was found to provide an adequate fit to data in which depression and facilitation were evident if the parameters describing the system were allowed to vary between each response.

Abstract:
The local approach to modelling ductile tearing is a useful technique to give insight into fracture mechanics. However, applications of the local approach have been stymied by the high cost of finding the parameters that characterize it because of the number of specimens and expensive post-processing that the testing requires. In this paper, a novel iterative method to extract a failure locus from one Crack Tip Opening Displacement (CTOD) specimen is presented. Material points fail under various different stress states in a CTOD specimen, so many different points on the failure locus can be found through thoughtful post-processing in FEA. A phenomological ductile failure locus is fitted through the stress triaxiality, Lode angle, and plastic strains that cause failure at material points in the CTOD test. Simulating a CTOD test with a different aspect ratio has shown that the failure locus found by this method can be predictive, giving both accurate force versus Crack Mouth Opening Displacement (CMOD) curves and realistic fracture surfaces featuring separate tunnelling and shear lips.

Abstract:
Abstract With increase of machine speed, the influence of elastic components on dynamic characterises has become a very challenging problem. In our paper, we use self-made fiber-optic sensor on-line to detect the elastic locus. The sensor has highly transmitting and collecting light properties so that steady elastic locus has high precision and distinguishabilty. A theoretical analysis has been conducted using our program KEDL. The conclusions reveal more information about the dynamic characteristics of high-speed mechanisms.

Abstract:
Previous studies have indicated that the majority of haemophilia B patients who produce anti-factor IX inhibitors (antibodies) have some kind of deletion of the factor IX gene. We have analysed DNA from nine haemophilia B inhibitor patients using the Southern blotting method and hybridisation with (i) factor IX cDNA and intragenomic probes (ii) probes originating from flanking sequences up to 60kb 5' and 170kb 3' to the factor IX gene that have been isolated by gene walking experiments (D.S.Anson and G.G.Brownlee, unpublished observations).Two patients who are brothers (haemophilia B (Chicago I)) were shown to have a presumably identical complex rearrangement of the factor IX gene involving two separate deletions. The first deletion is approx. 5.0kb and removes exon e. The second deletion is between 9 and 29kb and removes exons g and h but leaves exon f intact. An abnormal TaqI fragment at one end of the deletions junctions acted as a marker for the inheritance of haemophilia B in the patients' family. Furthermore, an abnormal llkb Bglll fragment (detected with an intragenomic probe containing exon f) in DNA from both patients and their mother acted as a marker for the presence of both deletions. Since the patients' grandmother only showed the normal 12kb Bgl II fragment then both deletions appear to have arisen at the same time. We believe that haemophilia B (Chicago 1) is the first observation of a natural gene rearrangement involving two separate deletions within the same gene.Patient haemophilia B (Jersey 1) was revealed to have a deletion of at least 170kb including the entire factor IX gene and > 60kb of 5' flanking sequence. The 3' breakpoint of this deletion was mapped to between 80 and 140kb 3' to the factor IX gene. One further patient, haemophilia B (Boston I) was shown to have a deletion of > 230kb including the factor IX gene, > 60kb of 5' flanking sequence and >140kb of 3' flanking sequence. Five other inhibitor patients had a structurally intact gene as detected by this method.Although all nine haemophilia B inhibitor patients studied did not have a detectable plasma factor IX only in four of them is this absence due to a large deletion of the factor IX gene.

Abstract:
Abstract In this work, the properties of the class of parallel feedforward compensators to stabilize linear closed-loop systems are studied. The characteristic equation and its root locus behavior, including its asymptotes, are investigated to leave out the compensators that will not result in a stable closed-loop system. Even though there have been numerous studies relevant to parallel feedforward compensation that result in the optimal integration of squared errors (ISE), the broader view of all possible compensators has not been of much interest in the literature. Nevertheless, this study is important because, in the presence of noise and disturbance, an optimal ISE control design for the nominal plant may perform poorly while a finite ISE design may have a robust and efficient performance. One of such class compensators is parallel feedforward compensator with derivative effort (PFCD) that for a vast number of processes can have impressive properties such as no branch comebacks to the right half plane (RHP) of the root locus plot (LHP black hole effect). The example in this paper shows how effectively PFCD can contract the root locus branches into the LHP.

Abstract:
Managers are challenged with the impact of problematic plants, including exotic, invasive, and pest plant species. Information on the cover, distribution, and location of these plants is essential for developing risk-based approaches to managing these species. Based on surveys conducted in 2006, 2011, 2015, and 2019, Heartland Network staff and contractors identified a cumulative total of 28 potentially problematic plant taxa in Arkansas Post National Memorial. Of the 23 species found in 2019, we characterized 9 as very low frequency, 7 as low frequency, 5 as medium frequency, and 2 as high frequency. Cover of all species was low with a single species slightly exceeding a 1-acre threshold based on a midpoint estimate. Efforts to control the woody invasive black locust, Chinese privet, and hardy orange appear to have successfully reduced the cover of these plants across the Memorial Unit. Japanese stiltgrass may have been increasing as recently as 2015, but a combination of recent flooding and control efforts may have stemmed the spread of this invasive grass. Efforts to control localized patches of Chinaberry tree also appear to have reduced the cover of this species. Outside of the problematic species currently subject

Abstract:
Situated in a complex region of the world, Puntland State in Somalia is dealing with a range of threats and instabilities such as droughts, floods, locusts, the movement of internally displaced people (IDPs), and armed actors. COVID-19 has added yet another strain on its tremendously fragile infrastructure. The impact of the pandemic has been far reaching, affecting livelihoods and hampering unpaid and underpaid care work and responsibilities. The multitude of crises and rates of inflation have left the majority of families food insecure and without income, halted education and health services, and exacerbated existing vulnerabilities and the incidence of violence. This gender analysis was conducted and funded by the German Federal Foreign Office (GFFO), in partnership with Oxfam in Somalia and KAALO, to better help local government bodies, agencies, NGOs, and INGOs grasp the differentiated impact of the crises on women, men, boys, and girls, and host and IDP communities, during this time of intense loss and instability. The analysis provides an overview of the experiences of the affected communities, and gives recommendations on how to address immediate concerns and plan future programming.
