Published: March 2022

In the current IS/IT era, service to consumers is an absolute must to be prepared to survive in business competition. Physical and logical attacks with the aim of disrupting information technology services for individuals/agencies/companies or reducing the performance of IS/IT used. The development of IoT in the industrial revolution 4.0, which is all online, is a challenge in itself, from a negative point of view, all of them are able to carry out attacks on ISP servers, often carried out by hackers. DDoS (Distributed Denial of Service) attacks are the most common attacks. The development of software for DDoS attacks is very much on the internet, including UDP Unicorn software to attack very easily and can be done by anyone. Software for real-time monitoring of DDoS attacks, one of which is the Telegram bot. Telegram is a messaging system centered on security and confidentiality, while bots are computer programs that do certain jobs automatically. Telegram bot is free, lightweight and multiplatform. In the case study, this research contains 10 access points to the internet that will be mitigated from DDoS attacks. In this study, it was found that DDoS attacks caused traffic to become very high/congested by fulfilling upload traffic so that legitimate traffic users could not access the internet, connection to the internet was slow, the traffic was also unnatural, making it unable to connect to wireless devices and making Mikrotik login page becomes unable to appear. The purpose of this study is to mitigate DDoS attacks with the help of telegram bots so as to facilitate the notification of DDoS attacks in the event of an attack so that it is fast to deal with and find the perpetrators of the attack. The conclusion of this study is that DDoS attacks using UDP unicorn software resulted in a traffic spike of 53.5 Mbps on the upload traffic side, causing traffic for legitimate/authenticated users to slow down. By using telegram bots to know DDoS attacks occur in real time with a success rate of attack detection up to 100% notifications on telegram bots. Mitigation of DDoS attacks takes steps to track users using the torch feature on the routerboard interface menu, trace internet connection lines using wired or wireless transmission media, and ensure always monitoring the proxy interface from winbox.

Published: March 2022

In this paper, a simple method was proposed to obtain hydroxyapatite (HA) and hydroxyapatite/partially hydrolysed polyacrylamide (HA/AD37) composite materials which where applied to lead retention from aqueous solution by means of the batch method. The characterization of the materials verified that the presence of AD37 created interconnected porosity in the composite HA/AD37 giving it a good swelling properties that conducted to an easy separation of the material from aqueous solutions. Retention experiments carried out by varying the dose of lead and the contact time between adsorbent and adsorbate showed that the maximum adsorption capacity (Qmax) obtained for 2072.2 mg/L as initial concentration of Pb2 + was equal to 984.63 mg/g for HA and 924.50 mg/g for HA/AD37. Furthermore, AD37 used alone cannot retain Pb2 + ions. Indeed, the calculated Qmax of AD37 part of the composite was of 806.57 mg/g. The obtained Qmax values was elevated more than the reported values in many literatures. Based on the correlation coefficient, the kinetic study proved that pseudo-second order model agrees well with the obtained experimental data for Pb2+ retention by both HA and HA/AD37. Also, isotherm study explored that adsorption of lead was best fitted by Langmuir model for HA and Temkin model for HA/AD37. At last, the mechanism of retention was probed by characterizing the adsorbents after contact with lead ions by XRD and SEM. The results showed the transformation of calcium-hydroxyapatite to different structures of lead hydroxyapatite confirming the presence of ion exchange mechanism between Ca2+ and Pb2+.

Published: March 2022

Phytoaccumulation of metals (Cd, Cr, Cu, Pb, Zn) in roadside grown wheat and maize varieties ( Pavon-76, Siettecerros, Zea mays L. and Zea mays everta L.) and the toxicity and phytoremediation capability of the plants was investigated. Four sampling sites, roadside (SU 1, SU 3) and distant sites (SU 2 and SU 4) were selected by principle to represent the level of pollution near major traffic routes and were the reference sampling points. Whole plant metal levels of the four crops were determined using the multi-elemental technique- Energy Dispersive X-ray Fluorescent (EDXRF) and double beam AAS at A.B.U Zaria. Plant uptake factor (PUF), soil-plant transfer coefficient (TC) and translocation factor (TF) was computed for each metal. Pearson correlation analyses between the risk assessment factors of the metals were evaluated. Results revealed a positive significant (P<0.05) relationship between PUF/TC and PUT/TF for Cr and Zn in Pavon-76, PUF/TC for Cr and Zn in the two species of Zea mays L. and Cu in Siettecerros indicates atmospheric inputs and special ability or strong selective ability of each of the crops to accumulate certain metals. The inverse correlation between PUF/TC, PUF/TF and TC/TF among the metals indicates the proximity of SU 1 to the major highway, influence of traffic density, atmospheric inputs and geological material and a combination of other factors. This study reveals the potentialities of these varieties of Wheat and Maize which are terrestrial higher plants as accumulators of metallic elements and phytoremediators of roadside soil pollution

This study was a clinic-based cross-sectional survey that was incorporated with quantitative and qualitative data collection. Information on sociodemographic characteristics of the caregivers was assessed with the aid of a validated semi-structured questionnaire. Weight, oedema, and Mid up Arm Circumference (MAUC) of the children were measured weekly to monitor the progress of the programme. This study shows that 8(26.67%) of the caregivers were aged 21 – 25 years and 26 - 30 years each, while 7 (23.33%) were 18 - 20 years of age, only 1(3.33%) of the caregiver was above 40 years. The mean age of the respondents was 27 years. Educational status shows that 17(56.67%) of the caregivers attended Secondary school as the highest level of education, 5(16.67%) had no formal education while only 1 attended tertiary institution. Occupation wise, 36.67% (n=11) of the caregivers were Artisan/Skilled Worker, followed by 10(33.33%) who were housewives. The result of the MUAC of the SAM children for 8 weeks shows that the mean value for the first week was 9.73. The boosters of the programme show 76.7% of RUTF, 10% of porridge beans, tofu and turn brown. The cost of transportation and distance as barriers was 60% and 26.7% respectively. The performance indicators show 77.8% cure rate, 8% default rate, 2.7% death rate and no recovery rate was 11.1%. Geographic coverage is 5.8% which when compared with the percentage standard is alarming. Therefore, geographic coverage in this study site was low and this would translate into low program effectiveness

Field trials were conducted during the 2017 wet season at the Dryland Teaching and Research Farm of , Usmanu Danfodiyo University Sokoto (Latitude 13o 7’N, Longitude 50 10’E’) and Dutsinma in Katsina State (longitude 70 29’E, Latitude 12o 27’N ). The aim was to evaluate Pendimethalin, Butachlor and S-Metolachlor for weed control in soya beans. Treatments consisted of Pendimethalin at 0.8, 1.0 and 1.2 kg a.i./ha, Butachlor at 1.5, 1.8 and 2.0 kg a.i./ha and S-Metolachlor at 0.6, 1.3 and 1.9 kg a.i./ha and control where weeding was done manually at 4 and 6 weeks after sowing. The experiment was laid out in a Randomized Complete Block Design and replicated three times. Data were collected on weed parameters. Results obtained indicated that all the herbicide treatments significantly reduced weed infestation during the first four weeks after sowing but the crop experienced competition with weeds thereafter which varied according to the types of herbicides and their rates. Pendimethalin (1.0 and 1.2 kg a.i./ha, S-Metholachlor (1.9 kg a.i./ha) and Butachlor (2.0 kg a.i./ha) exhibited superior performance over other herbicide treatments. However, Pendimethalin at 1.2 kg a.i./ha caused injury to the plants though not prolonged. Hoe weeded plots faced early competition with weeds but were relatively weed-free during the reproductive phase of the crop. Soya bean farmers in Katsina and Sokoto could apply Butachlor 2.0 kg a.i./ha or S-Metolachlor 1.9 kg a.i./ha or Pendimethalin 1.0 kg a.i./ha for good control of weeds during the establishment phase of soya bean.
