Assessment of Productivity Status Using Carlson’s TSI and Fish Diversity of Goronyo Dam, Sokoto State, Nigeria

Goronyo Dam is the largest lentic waterbody in Sokoto, it was constructed to serve as flood control and used for irrigation activities. The study was conducted to evaluate productivity status and fish diversity of Goronyo Dam in 2016. Water samples were collected monthly from the Dam at two sampling sites (Upstream and Downstream). Water samples were collected using sterilized sampling bottles and analyzed in the Laboratory for physicochemical variables and the diversity of fish was evaluated through the use of a structured questionnaire. Depth and transparency were the only variables that did not show any statistically significant difference between the months. Productivity status of the dam was evaluated using Carlson’s Trophic State Index. The downstream has high TSI value of 16.54 compared to upstream with 13.00. A diversity of fishes from the shows that 3 species were more abundant in the dam, these were; Mormyrops species, Alestes species and Clupeid species. Factors contributed to the survival of fish species were an abundance of water and plankton in the dam. While factors affecting the distribution of fish species were pollution and predation

MISYAR MARRIAGE: A Comparative Study on Yusuf Al-Qaradhawi And Suhailah Zainul Abidin Hammad Perspective

This study delves into the perspectives of Yusuf Al-Qaradhawi and Suhailah Zainul Abidin Hammad on the complex topic of Misyar marriage within the framework of Islamic jurisprudence. The objective of this study is to analyze and compare their viewpoints on the legitimacy, societal implications, and ethical dimensions of Misyar marriage within the Islamic context. Utilizing a qualitative approach, this study takes the form of a library research inquiry. Employing a descriptive-comparative approach, researcher scrutinize Misyar marriage law through the lenses of both Yusuf Al�Qaradhawi and Suhailah Zainul Abidin Hammad. The data was gathered from various documents, and the principal data originates from Al-Qaradhawi's book "Zawajul Misyar, Haqiqatuhu Wa Hukumuhu" and Suhailah's "Zawajul Misyar." Key findings reveal that Al-Qaradhawi tends to adopt a more lenient stance, emphasizing its potential to address specific societal needs. In contrast, Suhailah expresses significant reservations, highlighting potential exploitation and its consequences on familial relationships and broader societal dynamics

The Extended Edit Distance Metric

Similarity search is an important problem in information retrieval. This similarity is based on a distance. Symbolic representation of time series has attracted many researchers recently, since it reduces the dimensionality of these high dimensional data objects. We propose a new distance metric that is applied to symbolic data objects and we test it on time series data bases in a classification task. We compare it to other distances that are well known in the literature for symbolic data objects. We also prove, mathematically, that our distance is metric.Comment: Technical repor

Multiqubit quantum phase gate using four-level superconducting quantum interference devices coupled to superconducting resonator

In this paper, we propose a scheme to realize three-qubit quantum phase gate of one qubit simultaneously controlling two target qubits using four-level superconducting quantum interference devices (SQUIDs) coupled to a superconducting resonator. The two lowest levels |0> and |1> of each SQUID are used to represent logical states while the higher energy levels |2> and |3> are utilized for gate realization. Our scheme does not require adiabatic passage, second order detuning, and the adjustment of the level spacing during gate operation which reduce the gate time significantly. The scheme is generalized for an arbitrary n-qubit quantum phase gate. We also apply the scheme to implement three-qubit quantum Fourier transform. key words: quantum phase gate, superconducting quantum interference devices (SQUIDs), superconducting resonator, quantum Fourier transformComment: 14 pages, 7 figure
