The traditional English teaching focuses on the grammar and sentence structure but ignores the relationship between the sentences and paragraphs thus causing students’ lack of awareness of using cohesive devices. This study aims to illustrate the cohesion and coherence problems in college students’ writing. As one of the four basic language skills, English writing skill is the most indispensable but complicated one for English learners to master. According to College English Curriculum Requirement and under the theoretical framework of Halliday and Hasan’s Cohesion Theory, this study finds out the misuse of reference, substitution, ellipsis, conjunction and lexical cohesion in students’ English writing. By illustrating the examples of the discourse errors in students’ English compositions, this study tries to put forward some suggestions to ameliorate traditional English teaching and improve students’ writing skill.

Water samples of River Gwagwarwa and River Rafin Malam were subjected to liquid-liquid extraction and analyzed for organic pollutants. The organic parameters were determined using the standard methods of America Public health Agency (APHA) and was extracted and analyzed using Gas chromatography-mass spectrometer (GC-MS). Ten different organic compounds were detected at different percentage values at River Gwagwarwa while only seven different compounds were detected in River Rafin Malam. The compounds fall within five classes of organic compounds, which include carboxylic acid, acid chloride, ester, aldehyde and acid anhydride. The distribution pattern of the organic pollutants at the two sampling stations depict the pattern; River Gwagwarwa > River Rafin Malam. The study shows that organochlorine was the predominant organic pollutant present in River Gwagwarwa sample which is a hazardous pollutant while River Rafin Malam has no toxic pollutant which is attributed to lack of activity of the River.

The experiment was carried out at the Regional Agricultural Research Station, Jamalpur under Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur-1701 during the period from December, 2015 to April, 2016 to observe the effect of nitrogen and zinc on the growth and yield of late sown wheat. The experiment comprised four nitrogen levels viz. (i) N0= Control (No nitrogen), (ii) N1=140 kg ha-1, (iii) N2=160 kg ha-1, (iv) N3=180 kg ha-1 and five zinc levels viz. (i) Zn0 = Control (No zinc), (ii) Zn1= 2 kg ha-1, (iii) Zn2 = 4 kg ha-1, (iv) Zn3=6 kg ha-1, and (v) Zn4=8 kg ha-1. The experiment was laid out in a split-plot design with three replications assigning N-levels in the main plots and Zn-levels in the sub-plots. The interaction effect of N and Zn levels showed significant variation regarding grain yield and the highest grain yield (1.96 t ha-1) was found in N2Zn3 combination ascribed to the highest number of tiller (376.33 plant-1), grain (37.07 spike-1) and 1000-grain weight (36.26 g) significantly different from other combinations. Grain yield decreased significantly beyond the levels N2 and Zn3 due to their either individual effect or interaction effect. The lowest level, N0 and Zn0 gave significantly the lowest grain yield due to their either individual effect or interaction effect (0.69, 1.24 and 0.61 t ha-1 respectively).

The research also revealed thet postpartum mothers who experienced the decrease of low concentration (median 166.7 mg/L) 7.0 times more risk to experience the deficiency of cronic energy compared to the mother with postpartum good nutrition status.

Tetracera rosiflora Gilg is a medicinal plant used in the Congolese pharmacopeia for the treatment of various diseases. The aim of this work was to achieve the micrographic analysis of the powder of leaves of T. rosiflora from Pumbu City (Kinshasa) and Lukala areas (Kongo Central), to determine their chemical composition and to evaluate the antioxidant activities of their different extracts. Extracts from leaves of this species were characterized for their chemical fingerprint by Thin Layer Chromatography and their in vitro antioxidant activities were evaluated using ABTS, DPPH assays. Microscopically leaves can be characterised by non-glandular trichomes, sinuous anticlinal epidermal cells, and parenchymal cells with cristal of calcium oxalate, polycytic stomata and spiraled vessels. Thin Layer Chromatography showed that leaves of Tetracera rosiflora contain varied phytochemicals such as anthocyanins, flavonoids, coumarins, iridoids, phenolic acid, tanins and the terpenes. All tested extracts (methanolic and dichloromethane) have exhibited high antiradical activities. The obtained results showed that the interesting bioactivities of T. rosiflora correlated with the chemical composition, which depends on several factors including climatic conditions. T. rosiflora is a phytogenetic resource of the Congolese pharmacopoeia with promising therapeutic potentials for the management of various pathologies associated with oxidative stress.

A population of spiny-tailed lizard (Uromastyx aegyptia) exists in Hengam Island in the Persian Gulf. The field work was carried out over a period of 10 days by the use of a four-member group work in May 2015 through 10 random transects in the whole Island by the use of motorcycle. Once the animal’s cavity was found, some plots with dimensions of 10 by 10 meters were established over the center hole of the spiny-tailed lizard and habitat variables such as the region slope, geographical direction, type of the soil texture, percentage and number of plant cover according to species, distance to the nearest water source, road, and vegetation patches were measured. The habitat factors measured in the control points where there were no signs of the animal’s holes were also measured and compared with the present points. Ultimately, 28 holes of the spiny-tailed lizard in 7colony that had far from each other, were considered in the region. The results showed that the spiny-tailed lizard of the regions with a mean slope of 10% facing towards the north preferred rather semi hard soils (contain gravel and silt) (p<0.05). To protect the population of this species in the region, paying attention to some effective parameters such as the percentage cover of plant species, region slope and Acacia tree are of the most important factors for the use of the habitat of this species.

Brain tumors account for 85% to 90% of CNS tumors. In 20-40% of the patients suffering from brain tumor (BT), seizures are common during the commencement of the disease. The relationship between the onset of seizures and brain tumor is poorly understood. These patients show a complex therapeutic profile making selection of the drugs very tough. The quality of life of the patient is highly compromised due to brain tumor-related epilepsy (BTRE) as it is drug-resistant and poses the challenging risk factor for everlasting disability. Hence, there arise the need of unique and multidisciplinary approach of proper selection of medications with minimum side effects. Glioblastoma Multiforme is a grade IV highly malignant tumor attacking the glia, which provides nourishment and assist in signal transmission. Glioma cells secrete glutamate and choose neurotransmitter receptors for their invasive growth. Glutamate binds to ionotropic receptors, activate calcium release mediating excitatory neurotransmission. The alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors are the major mediators of glutamate-mediated excitatory neurotransmission and are critical for spread of epileptic activity. Glutamate is the main culprit for both the occurrence of seizures and glioma metastases. Hence there lies an opportunity to use the anti-epileptic drugs which targets calcium permeable AMPA receptors for the treatment of glioblastoma as well as BTRE. Topiramate (TPM), a derivative of D-fructose is a novel broad spectrum anti-epileptic drug which shows antagonistic effect on AMPA receptor. When treated with TPM a dose-dependent decrease in live cell number, increase in the number of apoptotic cells, decrease in the calcium influx, reduction in phosphorylation of Akt, Erk1/2 expression were observed. Also phosphorylation of AMPA receptor in presence of EGF was observed. The data suggests that topiramate lead to decrease in proliferation and survival by decreasing calcium influx and inhibiting mitogenic and survival signalling in U87MG cells.

Diversity and conservation status of plant species used for oral and dental management by the inhabitants of Bayelsa State, Nigeria were assessed. Information on the indigenous knowledge of the plant species use was obtained via semi-structured questionnaire guide, and field trip involved key informants. Species used for oral and dental care were identified, and their relative abundant status determined. The study revealed that different kinds of plant with varied growth habits were used for orodental care; however some of the plants are becoming rare due to unprecedented deforestation. Fidelity level (FL), and Respondents Consensus Factor (RCF) revealed the relative importance and level of respondents’ reliance on the plants. The study further showed that leaves, roots and plant inflorescence played significant role in oral treatment either singly or in combination of other plant parts steeped in ogogoro, a local gin. Many of the plants assessed were obtained from the wild, forest being their primary source. Thus, with the increasing level of deforestation in the State and the unsustainable collection pattern, combined with blasé attitude, the consequence of erosion of culture: it becomes pertinent to document information of plant species used for oral and dental management in the State.

Gold is a safe haven asset especially in times of uncertainties and can provide long-term capital gain. The objective of this study is to investigate the causality relationship among the changes of the Malaysia stock price index (KLCI), US stock price index (DOJ), Malaysian currency exchange rate (EXR) and crude oil price (COP) on the gold price (POG) in the Malaysian Market. This study employs vector error correction method with co-integration analysis, Granger causality test, and model evaluation. Based on the findings, COP and the lagged of the gold price (POG) only have a significant short-term relationship, however, the KLCI, DOJ, EXR and COP has also a significant long-term relationship with the gold price. Moreover, POG granger causes KLCI and COP also granger causes POG, both are uni-directional causality. Furthermore, EXR granger causes POG with bi-directional causality. Evidently, EXR and COP changes are importantly affecting the gold price changes. Otherwise, the gold price changes are affecting also the changes of KLCI and EXR in the study. These findings are important for investors who are opportunities for investment in gold in Malaysia.

The study investigated information sourcing situation surrounding crop farmers in Abak agricultural zone of Akwa Ibom State, Nigeria. Specifically, effective and responsive media sources were mapped in terms of availability, preference and Constraints to use among crop farmers in the study area. A multi-stage sampling technique was used in the selection of respondents. Preferred Sources of Information Questionnaire (PSIQ) with reliability index of 0.84 was administered on 90 Crop farmers in the study area. Data were analysed through the use of descriptive statistics. Findings revealed that the dominant age bracket constituted 64.5% of the sampled population. About 81.1% of the respondents were male and 55.6 % were married. 15.5% attended higher institution and 57.7% acquired SSC. Majority (52.22%) had between 3-10 years of farming experience while 66.67 % took crop farming as their primary occupation. 95.6% of the respondents identified mobile phones as their major available source of information while 92.2% identified both television and radio as their available sources of information. Other major available sources of information were internet (91.1%), co-farmers (90%), and extension agent (82.2%). Crop farmers association and posters (50%) each were considered the least available sources of information. Television and mobile phones with a mean value of 1.8 each were the most preferred sources of information utilized by crop farmers in the study area, followed by extension agents (1.6), internet (1.6) and co farmers (1.5). The results across all the constraints portrayed that almost all the identified constraints (16 out of 19) had influence on the utilization of available sources of information by the respondents. Adequate training centers, access to ICTs centers and increased extension agent ratio should be put in place to ameliorate the severity of the constraints faced by the respondents in utilizing the available sources of information in the study area.

Rosuvastatin calcium is hypolipidemic drug and has low oral bioavailability of about 20% due to poor aqueous solubility and hepatic first-pass metabolism. These are major boundaries inefficient delivery of RC by oral route. Several delivery approaches are known to moderate the difficulties of solubility and increase the oral bioavailability of RC. Among numerous approaches, nanotechnology-based delivery of RC has prospective to overcome the challenges associated with the oral administration. This review focuses on various nano-based delivery systems such as nanoparticles, lipid nanoparticles, SEDDS and SNEDDS and tried for improving the aqueous solubility, dissolution and subsequently bioavailability of RC upon oral administration. Of all, solid lipid nanoparticles appear to be promising delivery system, based on current reported results, for delivery of RC, as this system improved the oral bioavailability and possessed prolonged pharmacodynamic effect.

Ethanolic root extract of Solanum torvum Sw (Family: Solanaceae) was evaluated for its antihyperglycemic and antilipidemic activity in streptozotocin induced diabetic rats. The extract was given orally in two different doses (200 and 400 mg/kg) for 28 days. Metformin (2.5 mg/kg) was used as a standard drug for activity comparison. Various parameters studied were blood glucose concentration, serum lipids, glycosylated haemoglobin and liver glycogen. The extract showed significant antihyperglycemic activity in dose dependent manner. Further, the extract was favourably and significantly corrected the alterations in the values of the lipid parameters, organ weights, liver glycogen and glycosylated haemoglobin content in diabetic rats. Therefore, it may be suggested that the ethanolic root extract of Solanum torvum has potential ability to prevent the secondary complications of diabetes mellitus like atherosclerosis.

Water is one of the most natural resources in dry areas, as it controls the presence, distribution and density of plants, animals and humans. Water is scarce or non-existent on the surface of dry lands around the world, it is clearly characterized by the appearance of dry areas on the appearance of the adjacent rain areas, However, in order to utilize dry areas in grazing and in stable agriculture, in trade, in the utilization of mineral resources, and in the establishment of urban centers, water must be found in sufficient quantities that are reliable and have qualitative characteristics that allow for selected economic activity. The western Anbar Plateau (116,000), or 26.5% of Iraq's total area of 438,317 km2 and 84.2% of the Anbar region, is characterized by low water availability. It is therefore necessary to increase efforts and harness energies to discover new water sources which are represented by ground water that compensates for the shortage of surface water quantities, especially as its use (groundwater) began to increase in most countries of the world. Generally water is the source of life for all human creatures on the surface of this planet, In the near future; the conflict will also be over water rather than energy. Here the problem of the research appears which is identified by the following question: - Is there in the western plateau of Anbar, despite the large space occupied by the scarcity of water sources mature development projects rely primarily on the investment of groundwater reservoirs located therein, which contributes to the regular redistribution of the population. The hypothesis of the research was summarized as: - Defining the requirements of economic and social development that contribute to the foundations of human stability in that region by studying the groundwater and its areas of presence in the western plateau of Anbar.

H pylori infection is well known to be the most common human infection worldwide on the basis of the fact that approximately 50% of the worldwide populations are infected and that human beings are the main reservoir. Infection is more prevalent in developing countries, and incidence is decreasing in Western countries. Moreover, it has been proved to be associated to endocrine system regulation of various hormones in the body, prolactin (PRL) is one of the reproductive hormones, which is secreted by the anterior pituitary gland. The biological actions of prolactin hormone are Lactotrophic effects, metabolic effects influence to action of other hormones, osmoregulatory effects, and Influence of prolactin on the immunological system. This study was conducted in Khartoum State at the period from December 2015 to May 2016, and aimed to determine the possible effect of H. pylori infection on serum prolactin levels in Child-bearing females age (15 – 45). Sample size was 50 females infected with H. pylori and 50 uninfected females as control group. Stool Samples were taken from the entire study subject (100) samples to confirm the results of H. pylori Ab ICT in serum. The stool samples were analyzed by using H.pylori stool Ags detections ICT. Serum prolactin level was measured by using Cobas e411chemistry analyzer, the results showed that Prolactin concentration was higher in the patients compared with controls. In this study hyperprolactinemia due to H.pylori infection was reported in 52% of the patients. Statistical analysis showed that there was significant difference in the mean of prolactin concentration between infected and uninfected females group (P= 0.000). Regarding correlation between prolactin concentration and subject’s age, H. pylori infection duration or recurrence of infection, no significant was found to be observed.
