The endodontic preparation of curved and narrow root canals is challenging.
Aggressive preparation of the root canal with rotary file systems may result in canal
transportation and excess removal of dentine, a major reason for poor prognosis of root
canal treated tooth. The purpose of the present study was to compare the canal
transportation and centering ability of Rotary ProTaper Next (PTN) and HyFlex EDM
file systems using cone beam computed tomography (CBCT) in curved root canals.
Forty extracted human mandibular first molars were mounted on acrylic blocks.
Specimens were divided into two groups: Group PTN (ProTaper Next) and Group HF
(HyFlex EDM). Mesiobuccal canals were instrumented with ProTaper Next and HyFlex
EDM rotary files. Pre-instrumentation and Post-instrumentation scans were performed
using CBCT under similar conditions. Canal transportation, centering ratio and volume
of the dentine removed were evaluated at 3 cross-section levels; 3-mm, 6-mm and 9-
mm from the root apex. The data were statistically analyzed and the level of
significance was set at p ≤ 0.05.Canal transportation was seen minimal with HyFlex
EDM (0.021±0.009) at 3mm from the apex and maximum with ProTaper Next
(0.028±0.021) at 9mm from the apex. Mean centering ratio was lower for HyFlex EDM
to ProTaper Next at all levels. Both Pro Taper Next and HyFlex EDM systems shaped
the canals with adequate centering ability and minimal canal transportation. Hyflex
EDM better maintained canal centricity but the difference was not statistically
significant.

Abstract: Neuroinflammation, mediated by the reactivity of the system of cytokines, accompanies the flow of amyloidosis in Alzheimer’s disease, alongside with disturbances in the work of central departments of the olfaction analyzer. Therefore, it is advisable to determine the reactivity of the cytokine system in the brain sections of elderly rats (neocortex, hippocampus, olfaction bulbs, hypothalamus, caudate nuclei) under the conditions of the bulbar effect of β-amyloid peptide aggregates. The content of tumor necrosis factor α, interleukin-6 and interleukin-10 in the brain sections of the rats having the age of 18 months (n = 24) that are being studied was determined 5 days after the intrabulbar injection of the suspension of β-amyloid peptide 40 (Amyloid β Protein Fragment 1-40, Sigma-Aldrich, USA) in the bidistilate or the solvent itself. It has been shown that the initial level of activity of the cytokine system (intact animals of the control group, n = 8) in the brain sections that are tangent to the olfaction analyzer (neocortex, hippocampus and olfactory bulbs) is probably lower in comparison to other parts (hypothalamus and caudate nucleus) of elderly rats. Intraubulbar injection of β-amyloid peptide 40 aggregates to elderly rats (experimental group, n = 8) increases the activity of the cytokine system in the brain structures distant from the spot of injection (neocortex and hippocampus) responsible for memory mechanisms. It has been determined that the reactivity of the cytokine system in the neocortex, hippocampus and hypothalamus is higher not only in response to the specific toxic effects of the β-amyloid peptide 40 aggregates (experimental group, n = 8), but also due to surgical intervention with the injection of solvent alone (comparison group, n = 8). It has been generalized that the low content of pro- and anti-inflammatory cytokines in phylogenetically younger parts of the brain (neocortex, hippocampus) of intact animals corresponded to increased reactivity of the cytokine system under the influence of exogenous β-amyloid peptide 40.

Exchange rate is an important macroeconomic variable that economic planners,
policymakers as well as governments all over the world monitor very closely. This may
be because volatility in exchange rate is capable of putting an entire nation in an acute
state of disequilibrium. In Nigeria, economists and other stakeholders have continued to
make relevant efforts to restore normalcy/stability to the nation’s exchange rate that has
been subjected to severe rate of volatility in recent years. The Nigerian industrial sector
remains a potentially viable alternative amidst the incessant widespread calls for
diversification of the Nigerian economy. As such, it is not against conventional wisdom to
say that since industrialisation may involve importation (of raw materials), exportation (of
finished goods) or both; one may not be wrong to expect a link with exchange rate.
Therefore, this study investigated the relationship between exchange rate volatility and
industrial sector performance in Nigeria using quarterly time series data spanning from
1980Q1 to 2016Q4. The researchers relied on the use of OLS multiple regression
technique for analysis while exchange rate volatility was generated using Exponential
Generalised Autoregressive Conditional Heteroskedasticity (EGARCH). The result
showed that exchange rate volatility is inversely related to industrial sector performance
(using industrial sector contribution to GDP as a proxy) in Nigeria. Furthermore, trade
openness was observed to have a negative sign (though statistically insignificant) while
exchange rate and interest were also found to be strong and significant positive drivers of
industrial sector performance in Nigeria. Following the findings, the Nigeria government
and other stakeholders are advised to hasten efforts to arrest the perennial fluctuations in
exchange rate in the country in order to stimulate expansion of productivity in industrial
sector.

10.36348/sjef
According to the development trend of the transportation industry and rapid
economic growth, China has carried out strategic layout and planning routes for the
transportation industry. The National Development and Reform Commission have also
issued a number of documents that promote the construction of a modern transportation
system, and promote transportation projects such as railways, waterways, airports, and
urban transportation. Besides, it continuously invests large amounts of money in
companies in the transportation industry. The mission of companies in the transportation
industry is of great importance. It can be seen that China’s transportation industry is at a
stage of rapid development, and it has received strong support from the government.
Nevertheless, it still has a long way to go. To improve the transportation infrastructure of
the nation, companies in the transportation industry must strive to improve their corporate
performance. This paper empirically investigates the impact of factors such as financial
factors, internal operations, and corporate growth on the corporate performance of listed
companies in the transportation industry, with the aim of helping listed companies in the
transportation industry to develop a sound corporate strategy and conduct standardized
and effective management to improve corporate performance. This paper selects data of
42 listed companies in the transportation industry from 2012 to 2016, and utilizes the
fixed effect model that controls heteroskedasticity to analyze influencing factors of the
corporate performance of listed companies in the transportation industry. Empirical
results show that core ratio, return on personnel, long-term debt ratio, and quality of staff
positively influences the corporate performance of listed companies in the transportation
industry. Factors such as operation cost ratio, managerial cost ratio, size, and delay ratio
have a negative impact on the corporate performance of listed companies in the
transportation industry. Policy implications are proposed accordingly.

10.36348/sijlcj.2018.v01i04.001
The existence in a country of groups of people that radically differ in culture, population and ethnicity may almost always generate fears of domination of minority groups by the majority groups. This paper examines the legal and political steps taken by the Nigerian Government to protect the interests of minority groups within its borders. Efforts have been made to discuss such steps as: state creation; fundamental human rights; federal character; resources derivation, allocation and utilization; and commissions set up to carter for the welfare of the minority groups. A brief discussion of minority questions on international plane is, also, undertaken. In order to achieve the above stated goals, reliance has been placed on the Constitutions of Nigeria 1979 and 1999, statutes, judicial authorities, international legal instruments and practical experiences. This is followed with recommendations and conclusion

The study measured the impact of exchange rate to financial remittance in
Nigeria for the period 1990 to 2016 using the traditional ordinary least square method for
estimation. Also, empirical and theoretical evidence from Nigeria. Africa and the
continent was compared. The analyses of the OLS regression showed evidence that real
effective exchange rate positively and significantly impacted on financial remittance in
Nigeria. Similarly, estimates from the ordinary least square model provide evidence to
show that exchange rate also positively significantly impacted on other macroeconomic
variables such as money supply but negatively to economic growth under the period of
the study. The result points to the fact that the macroeconomic variables and financial
remittance in Nigeria if well managed can engineer the Nigerian economy to greater
growth.

Ileal perforation is a common complication of Typhoid in developing countries other causes includes tuberculosis, trauma, and enteritis. Non-traumatic perforation is a challenge for surgeons because of considerable morbidity and mortality. This study tried to evaluate the etiology and clinical outcomes of surgical management for all the cases of non-traumatic ileal perforation. This prospective cross-sectional study was conducted in the Department of General Surgery, Prathima Institute of Medical Sciences, Naganoor, Karimnagar. Inclusion criteria were all the patients above 15 years undergoing surgery for ileal perforation. Excluded patients were those with appendicular perforations, peritonitis, and traumatic perforations. Based on the inclusion and exclusion criteria of 21 male and 17 female patients were included in the study. A thorough clinical examination of the patient including vital signs, abdominal distension, guarding and tenderness was done and noted. The laboratory investigations included Hemoglobin, BT & CT, and serum creatinine. Chest X rays, ECG, Blood culture and WIDAL tests were done to diagnose patients with typhoid. Results: In the present study out of 22 male patients 17 were diagnosed with typhoid perforation and 5 were a non-specific perforation. In the 17 females, 15 were diagnosed with typhoid perforation and 2 were non-specific perforations. The surgical approach for the management included primary closure in the total of 25 (64.10%) male and female patients followed by Ileostomy in 8 (20.51%), Ileo Transverse Anastomosis in 4 (10.26%) and resection anastomosis in 2 (5.12%) of cases. Conclusion: Within the limitations of the present study it can be concluded that typhoid ileal perforations are common in the group of patients reaching our hospital. The operative treatment for intestinal perforations should be based on several factors including operative findings. Early surgery with skilled surgeons and good postoperative care will result in reduced morbidity and mortality.

Economic development of a village will be successful if there is participation
from entrepreneurs who are expected to create jobs. Entrepreneurship is a development
potential that can drive the economy of a village, therefore, it is very necessary to
empower the businesses that are expected to be able to develop the potential of the village
through innovation and creativity. So that this can be achieved, it needs support from
various parties and one of them is a Village-Owned Enterprise (BUMDesa). BUMDesa is
intended to strengthen village income, increase business opportunities, reduce
unemployment and at the same time become the motor of the village economy. The
existence of MSMEs with BUMDesa is supposed to go together, this is because if the
economy wants to advance then the small businesses owned by the community must be
supported by advanced and organized management. In addition there are other factors that
can support the success and sustainability of a business, namely human resources. As a
business manager, it is required to have an entrepreneurial spirit, where the spirit of
entrepreneurship can be formed through the world of education and non-education and
this is the duty of universities to provide supplies and motivate graduates to become
entrepreneurs.

Abstract: Management of heart disease complicating pregnancy in a tertiary care centre is a great challenge to obstetricians and cardiologists. To know the maternal perinatal outcome of heart disease complicating pregnancies so that the quality of treatment in a tertiary care centre can be improved. Cardiac disease in pregnant women most commonly due to RHD, CHD, less commonly due to ischemic heart disease or cardiomyopathy. Though the frequency of RHD has decreased worldwide but still in developing countries like India, RHD is predominant. Admission of heart disease in pregnant women is approximately 30 of 2278 total deliveries from the month of june2018 to august2018 in MGMGH. The purpose of this study is to analyse all heart diseases in pregnancy and to characterize the clinical course, treatment and perinatal outcome in antenatal and postnatal women. Details of all antenatal or women less than 6 weeks postpartum admitted to MGMGH in the month of june to august 2018 were reviewed. Obstetric data included gestational age at the time of delivery, type, indication , location of delivery, congenital , rheumatic heart disease, operated , newly diagnosed were categorised depending on the major system involved. Out of 2278 deliveries from june2018 to august2018 in MGMGH, Trichy, 30 were heart disease complicating pregnancy. Rheumatic heart disease and congenital heart disease were more common. Operated congenital heart disease was also more common. Postnatally most of them required ICU monitoring and management. Incidence of Postpartum cardiomyopathy was very less in this study. Early anticipation of complications and close monitoring in the antenatal and perinatal period decreased maternal morbidity and mortality.

An Exposition of the Companions of Prophet Muhammad (SAW) and Their Yearnings for his Barakah
Usman Jimoh Muhammad
Page no 1169-1175 |
10.21276/sjhss.2018.3.10.4
The paper dwells on the concept of Barakah (blessing) reiterating its origin
and the position of the Prophet as the most blessed of all the creations. The concept of
Barakah as explored in the paper belongs to Allah who allots it to His creatures
according to His will and mercy. The paper focuses mainly on how the companions of
the Prophet acquired the Barakah of the Prophet. Reference is made to authentic
Prophetic traditions on how the companions of the Prophet yearned for the blessing in
his hair and in the fragrance of his sweat. The companions had also contested for leftover water of his ablution in order to gain Barakah. It is in the light of this that that the
paper discusses the emphasis of the Glorious Qur’an and the Sunnah on the relevance
of the barakah of the Prophet in averting the wrath of Allah as well as the effect of the
blessings of the Prophet on food and water. As states in the paper, strict compliance
with the teachings of the Prophet accorded the companions of the Prophet his blessings.
The paper recommends to the Muslims the need to believe that the Prophet is a mercy
to mankind and his blessing could be acquired through invocation of blessing on him
and compliance with his teachings.
